A simple command-line Matrix client
Project description
PRE-INSTALLATION
Before you install matrix-commander with pip install matrix-commander
you must have followed these prerequisites steps! Otherwise pip will fail.
-
Note that even if you install via
pipyou must have a) Python 3.8+ and b)libolminstalled. -
Run
python -Vto get your Python version number and assure that it is 3.8+. -
For e2ee support, python-olm is needed which requires the libolm C library (version 3.x). See also https://gitlab.matrix.org/matrix-org/olm. Make sure that version 3 is installed. Version 2 will not work. To install
libolmdo this:- On Debian, Ubuntu and Debian/Ubuntu derivative distributions:
sudo apt install libolm-dev - On Fedora or Fedora derivative distributions do:
sudo dnf install libolm-devel - On MacOS use brew:
brew install libolm
- On Debian, Ubuntu and Debian/Ubuntu derivative distributions:
-
For macOS Monterey 12.4 (21F79) (Apple M1 Pro) and similar please follow these steps for installation:
- Install
libolm,dbusandlibmagicusing Homebrew:brew install libolm dbus libmagic
- Install
matrix-commanderusing this command:pip3 install --global-option=build_ext --global-option="-I/opt/homebrew/include/" --global-option="-L/opt/homebrew/lib/" matrix-commander
- For more details see Issue #79. Thanks to @KizzyCode for the contribution.
- Install
-
For macOS x86_64 and similar please follow these steps for installation:
brew install libolm dbus libmagicpip3 install poetrypip3 install --global-option=build_ext --global-option="-I/usr/local/include/" --global-option="-L/usr/local/lib/" matrix-commander- Notice that the Link and Include directories between ARM (M1, etc.)
and x86-64 are different.
So, check for example where file
olm.his located on your hard disk. That gives you a hint which Include directory to use. - For more details see Issue #103. Thanks to @johannes87 for the contribution.

Summary, TLDR
This simple Matrix client written in Python allows you to send and receive messages and files, verify other devices, and interact with your Matrix account or other Matrix users in many ways. You use it from the terminal (CLI) or integrate it into other simple Python programs. Enjoy and please :star: star on Github.
matrix-commander
Simple but convenient CLI-based Matrix client app for sending, receiving, creating rooms, inviting, verifying, and so much more.
matrix-commanderis a simple command-line Matrix client.- It is a simple but convenient app to
- send Matrix text messages as well as text, image, audio, video or other arbitrary files
- listen to and receive Matrix messages, images, audio, video, etc.
- download media files like images or audio
- perform Matrix emoji verification
- performs actions of rooms (create rooms, invite to rooms, etc.)
- list rooms and room members
- and much more
- It exclusively offers a command-line interface (CLI).
- Hence the word-play: matrix-command(lin)er
- There is no GUI and there are no windows (except for pop-up windows in OS notification)
- It uses the matrix-nio SDK
- Both
matrix-nioandmatrix-commanderare written in Python 3 - Convenient to install via
pip.
What for? Why? For whom? Use cases?
Use cases for this program could be
- a bot or part of a bot,
- to automate sending via programs and scripts
matrix-nio show case: as educational material that showcases the use of thematrix-nioSDKalerter: to send all sorts of alerts,Gitlab CI automation tool: some user uses it as Gitlab CI automation tool to report build success/failure to their internal Matrix room. See Issue #81.admin toolorautomation tool: you needs to create 175 room for the roll-out within a company? You want to query some 9000 rooms for visibility data? You want to collect profile data of 7000 enterprise or public users?matrix-commanderhas many admin capabilities and can automate many tasks completely. Many admin jobs can be reduced to running a simple bash script or a simple Python program usingmatrix-commander.reminder: send yourself or others daily/weekly reminders via a cron job.surf report: an addict surfer usesmatrix-commandercombined with acronjob to publish daily early morning surf reports for his 3 favorite surfing spots to his Element app.juke box: a user told me he has a large collection of mp3 files on his server. He usesmatrix-commanderto send himself a random song from his music collection to brighten his day.ticker: many people send themselves stock prices from one of the many public ticker APIs. This is usually a singlecurlcommand piped intomatrix-commander.poor-man's Matrix client: if you love the terminal and are too lazy to start up an Element desktop app or an Element webpage,matrix-commanderis a a trivial way to fire off some instant messages to your friends from the terminal.poor-man's importer or exporter: you want to get things in and out of Matrix? Send those 39 holiday picture you have laying around in a holiday folder? Or, your best friend just sent you 57 wedding pictures on Element and you want to store them?matrix-commandercan help with importing and exporting data.poor man's blogger: a "blogger" who frequently sends messages and images to the same public room(s) could usematrix-commanderto keep his audience informed.poor man's diary: a person could write a diary or run a gratitude journal by sending messages to her/his own diary room or gratitude room.ghost:matrix-commandercan be used in an ephemeral fashion, in a fire-and-forget style. A single batch command can log in, create a new device, send a message, and then log out and delete the device.

First Run, Set Up, Credentials File, End-to-end Encryption
On the first run matrix-commander must be executed with the
--login argument and the corresponding secondary arguments.
This creates a credentials.json file.
The credentials.json file stores: homeserver, user id,
access token, device id, and default room id. On the first run,
the --login run, it asks some questions if not everything is
provided by arguments, creates the token and device id
and stores everything in the credentials.json file. If desired,
all arguments can be provided via arguments to that log in can
be performed fully in batch.
Since the credentials file holds an access token it should be protected and secured. One can use different credential files for different users or different rooms.
On creation the credentials file will by default be created in the local directory, so the users sees it right away. This is fine if you have only one or a few credential files, but for better maintainability it is suggested to place your credentials files into directory $HOME/.config/matrix-commander/. When the program looks for a credentials file it will first look in local directory and then as secondary choice it will look in directory $HOME/.config/matrix-commander/.
If you want to re-use an existing device id and an existing access token, you can do so as well, just manually edit the credentials file. However, for end-to-end encryption this will NOT work.
End-to-end encryption (e2ee) is enabled by default. It cannot be turned off.
Wherever possible end-to-end encryption will be used. For e2ee to work
efficiently a store directory is needed to store e2ee data persistently.
The default location for the store directory is a local directory named
store. Alternatively, as a secondary choice the program looks for a store
directory in $HOME/.local/shared/matrix-commander/store/. The user can always
specify a different location via the --store argument. The store
directory will usually be created on the first run.
For specific use cases end-to-end encryption can be disabled. Please see
description of flag --plain for details.
From the second time the program is run, and on all future runs it will use the homeserver, user id and access token found in the credentials file to log into the Matrix account. Now this program can be used to easily send simple text messages, images, and so forth to the just configured room.
Verification
As second step after the --login, it is recommended to perform an
emoji verification by running --verify. Verification is always
interactive, bacause the emojis need to be confirmed via the keyboard.
If desired --login and --verify can be done in the same first run.
The program can accept verification request and verify other devices
via emojis. See --verify in help for more details.
Room Operations, Actions on Rooms
The program can create rooms, join, leave and forget rooms. It can also send invitations to join rooms to others (given that user has the appropriate permissions) as well as ban, unban and kick other users from rooms.
Sending
Messages to send can be provided
- in the command line (-m or --message)
- as input from the keyboard (if there is no other input or command)
- through a pipe from stdin (|), i.e. piped in from another program.
For sending messages the program supports various text formats:
- text: default
- html: HTML formatted text
- markdown: MarkDown formatted text
- code: used a block of fixed-sized font, ideal for ASCII art or tables, bash outputs, etc.
- notification
- split: splits messages into multiple units at given pattern
Photos and images that can be sent. That includes files like .jpg, .gif, .png or .svg.
Arbitrary files like .txt, .pdf, .doc, audio files like .mp3 or video files like .mp4 can also be sent.
Matrix events like sending an emoji reaction, replying as a thread, message edits can be sent.
Listening, Receiving
One can listen to one or multiple rooms. Received messages will be displayed on the screen. If desired, optionally, you can be notified of incoming messages through the operating system standard notification system, usually a small pop-up window.
Messages can be received or listened to various ways:
- Forever: the program runs forever, listens forever, and prints all messages as they arrive in real-time.
- Once: the program prints all the messages that are waiting in the queue, i.e. all messages that have been sent in, and after printing them the program terminates.
- Tail: prints the last N read or unread messages of one or multiple specified rooms and after printing them the program terminates.
When listening to messages you can also choose to download and decrypt media. Say, someone is sending a song. The mp3 file can be downloaded and automatically decrypted for you.
Dependencies and Installation
-
If you install via
pip, thenpipwill take care of most of the dependencies.- See https://pypi.org/project/matrix-commander
- Usually
pip install matrix-commanderwill do the trick. - But, note that even if you install via
pipyou must have a) Python 3.8+ and b)libolminstalled. SeePyPi-Instructions.md. - Run
python -Vto get your Python version number and assure that it is 3.8+. - For e2ee support, python-olm is needed which requires the libolm C
library (version 3.x). See also https://gitlab.matrix.org/matrix-org/olm.
Make sure that version 3 is installed. Version 2 will not work.

If you install a docker image:
matrix-commanderis available on Docker Hub and hence easy to install as docker image (:clap: to @pataquets for his PR). Install viadocker pull matrixcommander/matrix-commander. -
If you install it via
gitor via file download then these are the dependencies that you must take care of:- Python 3.8 or higher installed (3.7 will NOT work)
- libolm-dev must be installed as it is required by matrix-nio
- libolm-dev on Debian/Ubuntu, libolm-devel on Fedora, libolm on MacOS
- matrix-nio must be installed, see https://github.com/poljar/matrix-nio
- pip3 install --user --upgrade matrix-nio[e2e]
- python3 package markdown must be installed to support MarkDown format
- pip3 install --user --upgrade markdown
- python3 package python_magic must be installed to support image sending
- pip3 install --user --upgrade python_magic
- if (and only if) you want OS notification support, then the python3
package notify2 and dbus-python should be installed
- pip3 install --user --upgrade dbus-python # optional
- pip3 install --user --upgrade notify2 # optional
- python3 package urllib must be installed to support media download
- pip3 install --user --upgrade urllib
- python3 package pyxdg must be installed to support
XDG_*env vars. Be careful. Multiple packages install in the same directoryxdgand overwrite each other. These packages can be conflicting. Specifically, packagespyxdgandxdgcollide. If you already havexdginstalled you cannot just simply installpyxdg; in this case you should opt for a separate Python environment.- pip3 install --user --upgrade pyxdg
matrix_commander/matrix_commander.pyfile must be installed, and should have execution permissions- chmod 755 matrix_commander.py
matrix_commander/matrix-commanderfile is recommended for the install, and should have execution permissions- chmod 755 matrix-commander
- for a full list or requirements look at the
requirements.txtfile- run
pip install -r requirements.txtto automatically install all required Python packages - if you e.g. run on a headless server and don't want dbus-python and
notify2, please remove the corresponding 2 lines from
the
requirements.txtfile
- run
Examples of calling matrix-commander
- Alternative 1: Usually
matrix-commanderis called from a terminal inside a shell likebash,sh,zsh, your Windows CMD terminal or similar. You will find plenty of examples how to use it within a terminal just a few lines down. - Alternative 2: Sometimes, however, it might be more convenient to call
matrix-commanderfrom within a Python program. This is also possible. Import the Python modulematrix_commanderand use the provided entry pointmain. An example of how this can be done can be found in tests/test-send.py.
$ matrix-commander --login password # first run; will configure everything
$ matrix-commander --login sso # alternative first run with Single Sign-On;
$ # this will configure everything on a headless server w/o a browser
$ # this created a credentials.json file, and a store directory.
$ # optionally, if you want you can move credentials to app config directory
$ mkdir $HOME/.config/matrix-commander # optional
$ mv -i credentials.json $HOME/.config/matrix-commander/
$ # optionally, if you want you can move store to the app share directory
$ mkdir $HOME/.local/share/matrix-commander # optional
$ mv -i store $HOME/.local/share/matrix-commander/

Welcome to matrix-commander, a Matrix CLI client. ─── On first run use --login
to log in, to authenticate. On second run we suggest to use --verify to get
verified. Emoji verification is built-in which can be used to verify devices.
On further runs this program implements a simple Matrix CLI client that can
send messages, listen to messages, verify devices, etc. It can send one or
multiple message to one or multiple Matrix rooms and/or users. The text
messages can be of various formats such as "text", "html", "markdown" or
"code". Images, audio, arbitrary files, or events can be sent as well. For
receiving there are three main options: listen forever, listen once and quit,
and get the last N messages and quit. End-to-end encryption is enabled by
default and cannot be turned off, but it can be disabled for specific use
cases. ─── Bundling several actions together into a single call to matrix-
commander is faster than calling matrix-commander multiple times with only one
action. If there are both 'set' and 'get' actions present in the arguments,
then the 'set' actions will be performed before the 'get' actions. Then send
actions and at the very end listen actions will be performed. ─── For even
more explications and examples also read the documentation provided in the on-
line Github README.md file or the README.md in your local installation.
options:
-h, --help show this help message and exit
-d, --debug Print debug information. If used once, only the log
level of matrix-commander is set to DEBUG. If used
twice ("-d -d" or "-dd") then log levels of both
matrix-commander and underlying modules are set to
DEBUG. "-d" is a shortcut for "--log-level DEBUG". See
also --log-level. "-d" takes precedence over "--log-
level". Additionally, have a look also at the option "
--verbose".
--log-level LOG_LEVEL [LOG_LEVEL ...]
Set the log level(s). Possible values are "DEBUG",
"INFO", "WARNING", "ERROR", and "CRITICAL". If
--log_level is used with one level argument, only the
log level of matrix-commander is set to the specified
value. If --log_level is used with two level argument
(e.g. "--log-level WARNING ERROR") then log levels of
both matrix-commander and underlying modules are set
to the specified values. See also --debug.
--verbose Set the verbosity level. If not used, then verbosity
will be set to low. If used once, verbosity will be
high. If used more than once, verbosity will be very
high. Verbosity only affects the debug information.
So, if '--debug' is not used then '--verbose' will be
ignored.
--login LOGIN_TYPE Login to and authenticate with the Matrix homeserver.
This requires exactly one argument, the login method.
Currently two choices are offered: 'password' and
'sso'. Provide one of these methods. If you have
chosen 'password', you will authenticate through your
account password. You can optionally provide these
additional arguments: --homeserver to specify the
Matrix homeserver, --user-login to specify the log in
user id, --password to specify the password, --device
to specify a device name, --room-default to specify a
default room for sending/listening. If you have chosen
'sso', you will authenticate through Single Sign-On. A
web-browser will be started and you authenticate on
the webpage. You can optionally provide these
additional arguments: --homeserver to specify the
Matrix homeserver, --user-login to specify the log in
user id, --device to specify a device name, --room-
default to specify a default room for
sending/listening. See all the extra arguments for
further explanations. ----- SSO (Single Sign-On)
starts a web browser and connects the user to a web
page on the server for login. SSO will only work if
the server supports it and if there is access to a
browser. So, don't use SSO on headless homeservers
where there is no browser installed or accessible.
-v [VERIFY_TYPE], --verify [VERIFY_TYPE]
Perform verification. By default, no verification is
performed. Possible values are: "emoji". If
verification is desired, run this program in the
foreground (not as a service) and without a pipe.
While verification is optional it is highly
recommended, and it is recommended to be done right
after (or together with) the --login action.
Verification is always interactive, i.e. it required
keyboard input. Verification questions will be printed
on stdout and the user has to respond via the keyboard
to accept or reject verification. Once verification is
complete, the program may be run as a service.
Verification is best done as follows: Perform a cross-
device verification, that means, perform a
verification between two devices of the *same* user.
For that, open (e.g.) Element in a browser, make sure
Element is using the same user account as the matrix-
commander user (specified with --user-login at
--login). Now in the Element webpage go to the room
that is the matrix-commander default room (specified
with --room-default at --login). OK, in the web-
browser you are now the same user and in the same room
as matrix-commander. Now click the round 'i' 'Room
Info' icon, then click 'People', click the appropriate
user (the matrix-commander user), click red 'Not
Trusted' text which indicated an untrusted device,
then click the square 'Interactively verify by Emoji'
button (one of 3 button choices). At this point both
web-page and matrix-commander in terminal show a set
of emoji icons and names. Compare them visually.
Confirm on both sides (Yes, They Match, Got it),
finally click OK. You should see a green shield and
also see that the matrix-commander device is now green
and verified in the webpage. In the terminal you
should see a text message indicating success. You
should now be verified across all devices and across
all users.
--logout LOGOUT_TYPE Logout this or all devices from the Matrix homeserver.
This requires exactly one argument. Two choices are
offered: 'me' and 'all'. Provide one of these choices.
If you choose 'me', only the one device matrix-
commander is currently using will be logged out. If
you choose 'all', all devices of the user used by
matrix-commander will be logged out. While --logout
neither removes the credentials nor the store, the
logout action removes the device and makes the access-
token stored in the credentials invalid. Hence, after
a --logout, one must manually remove creditials and
store, and then perform a new --login to use matrix-
commander again. You can perfectly use matrix-
commander without ever logging out. --logout is a
cleanup if you have decided not to use this (or all)
device(s) ever again.
-c FILE, --credentials FILE
On first run, information about homeserver, user, room
id, etc. will be written to a credentials file. By
default, this file is "credentials.json". On further
runs the credentials file is read to permit logging
into the correct Matrix account and sending messages
to the preconfigured room. If this option is provided,
the provided file name will be used as credentials
file instead of the default one.
-s STORE, --store STORE
Path to directory to be used as "store" for encrypted
messaging. By default, this directory is "./store/".
Since encryption is always enabled, a store is always
needed. The provided directory name will be used as
persistent storage directory instead of the default
one. Preferably, for multiple executions of this
program use the same store for the same device. The
store directory can be shared between multiple
different devices and users.
-r ROOM [ROOM ...], --room ROOM [ROOM ...]
Optionally specify one or multiple rooms via room ids
or room aliases. --room is used by various send
actions and various listen actions. The default room
is provided in the credentials file (specified at
--login with --room-default). If a room (or multiple
ones) is (or are) provided in the --room arguments,
then it (or they) will be used instead of the one from
the credentials file. The user must have access to the
specified room in order to send messages there or
listen on the room. Messages cannot be sent to
arbitrary rooms. When specifying the room id some
shells require the exclamation mark to be escaped with
a backslash. As an alternative to specifying a room as
destination, one can specify a user as a destination
with the '--user' argument. See '--user' and the term
'DM (direct messaging)' for details. Specifying a room
is always faster and more efficient than specifying a
user. Not all listen operations allow setting a room.
Read more under the --listen options and similar. Most
actions also support room aliases instead of room ids.
Some even short room aliases.
--room-default ROOM_DEFAULT
Optionally specify a room as the default room for
future actions. If not specified for --login, it will
be queried via the keyboard. --login stores the
specified room as default room in your credentials
file. This option is only used in combination with
--login. A default room is needed. Specify a valid
room either with --room-default or provide it via
keyboard.
--room-create ALIAS [ALIAS ...]
Create one or multiple rooms. One or multiple room
aliases can be specified. For each alias specified a
room will be created. For each created room one line
with room id and alias will be printed to stdout. If
you are not interested in an alias, provide an empty
string like "".The alias provided must be in canocial
local form, i.e. if you want a final full alias like
"#SomeRoomAlias:matrix.example.com" you must provide
the string 'SomeRoomAlias'. The user must be permitted
to create rooms. Combine --room-create with --name and
--topic to add names and topics to the room(s) to be
created. Rooms are by default created encrypted; to
overwrite that and to create a room with encryption
disabled use '--plain'. Room id, room alias,
encryption and other fields are printed as output, one
line per created room.
--room-dm-create USER [USER ...]
Create one or multiple DM rooms with the specified
users. For each user specified a DM room will be
created and the user invited to it. For each created
room one line with room id and alias will be printed
to stdout. The user must be permitted to create rooms.
Combine --room-dm-create with --name, --topic, --alias
to add names, topics and aliases to the room(s) to be
created.DM rooms are by default created encrypted; to
overwrite that and to create a room with encryption
disabled use '--plain'. Room id, room alias,
encryption and other fields are printed as output, one
line per created room.
--room-join ROOM [ROOM ...]
Join this room or these rooms. One or multiple room
aliases can be specified. The room (or multiple ones)
provided in the arguments will be joined. The user
must have permissions to join these rooms.
--room-leave ROOM [ROOM ...]
Leave this room or these rooms. One or multiple room
aliases can be specified. The room (or multiple ones)
provided in the arguments will be left.
--room-forget ROOM [ROOM ...]
After leaving a room you should (most likely) forget
the room. Forgetting a room removes the users' room
history. One or multiple room aliases can be
specified. The room (or multiple ones) provided in the
arguments will be forgotten. If all users forget a
room, the room can eventually be deleted on the
server.
--room-invite ROOM [ROOM ...]
Invite one ore more users to join one or more rooms.
Specify the user(s) as arguments to --user. Specify
the rooms as arguments to this option, i.e. as
arguments to --room-invite. The user must have
permissions to invite users.
--room-ban ROOM [ROOM ...]
Ban one ore more users from one or more rooms. Specify
the user(s) as arguments to --user. Specify the rooms
as arguments to this option, i.e. as arguments to
--room-ban. The user must have permissions to ban
users.
--room-unban ROOM [ROOM ...]
Unban one ore more users from one or more rooms.
Specify the user(s) as arguments to --user. Specify
the rooms as arguments to this option, i.e. as
arguments to --room-unban. The user must have
permissions to unban users.
--room-kick ROOM [ROOM ...]
Kick one ore more users from one or more rooms.
Specify the user(s) as arguments to --user. Specify
the rooms as arguments to this option, i.e. as
arguments to --room-kick. The user must have
permissions to kick users.
-u USER [USER ...], --user USER [USER ...]
Specify one or multiple users. This option is
meaningful in combination with a) room actions like
--room-invite, --room-ban, --room-unban, etc. and b)
send actions like -m, -i, -f, etc. c) some listen
actions --listen, as well as d) actions like --delete-
device. In case of a) this option --user specifies the
users to be used with room commands (like invite, ban,
etc.). In case of b) the option --user can be used as
an alternative to specifying a room as destination for
text (-m), images (-i), etc. For send actions '--user'
is providing the functionality of 'DM (direct
messaging)'. For c) this option allows an alternative
to specifying a room as destination for some --listen
actions. For d) this gives the otion to delete the
device of a different user. ----- What is a DM?
matrix-commander tries to find a room that contains
only the sender and the receiver, hence DM. These
rooms have nothing special other the fact that they
only have 2 members and them being the sender and
recipient respectively. If such a room is found, the
first one found will be used as destination. If no
such room is found, the send fails and the user should
do a --room-create and --room-invite first. If
multiple such rooms exist, one of them will be used
(arbitrarily). For sending and listening, specifying a
room directly is always faster and more efficient than
specifying a user. So, if you know the room, it is
preferred to use --room instead of --user. For b) and
c) --user can be specified in 3 ways: 1) full user id
as in '@john:example.org', 2) partial user id as in
'@john' when the user is on the same homeserver
(example.org will be automatically appended), or 3) a
display name as in 'john'. Be careful, when using
display names as they might not be unique, and you
could be sending to the wrong person. To see possible
display names use the --joined-members '*' option
which will show you the display names in the middle
column.
--user-login USER_LOGIN
Optional argument to specify the user for --login.
This gives the otion to specify the user id for login.
For '--login sso' the --user-login is not needed as
user id can be obtained from server via SSO. For '--
login password', if not provided it will be queried
via keyboard. A full user id like '@john:example.com',
a partial user name like '@john', and a short user
name like 'john' can be given. --user-login is only
used by --login and ignored by all other actions.
--name NAME [NAME ...]
Specify one or multiple names. This option is only
meaningful in combination with option --room-create.
This option --name specifies the names to be used with
the command --room-create.
--topic TOPIC [TOPIC ...]
Specify one or multiple topics. This option is only
meaningful in combination with option --room-create.
This option --topic specifies the topics to be used
with the command --room-create.
--alias ALIAS [ALIAS ...]
Specify one or multiple aliases. This option is only
meaningful in combination with option --room-dm-
create. This option --alias specifies the aliases to
be used with the command --room-dm-create.
-m TEXT [TEXT ...], --message TEXT [TEXT ...]
Send this message. Message data must not be binary
data, it must be text. If no '-m' is used and no other
conflicting arguments are provided, and information is
piped into the program, then the piped data will be
used as message. Finally, if there are no operations
at all in the arguments, then a message will be read
from stdin, i.e. from the keyboard. This option can be
used multiple times to send multiple messages. If
there is data piped into this program, then first data
from the pipe is published, then messages from this
option are published. Messages will be sent last, i.e.
after objects like images, audio, files, events, etc.
Input piped via stdin can additionally be specified
with the special character '-'. If you want to feed a
text message into matrix-commander via a pipe, via
stdin, then specify the special character '-'. If '-'
is specified as message, then the program will read
the message from stdin. If your message is literally
'-' then use '\-' as message in the argument. '-' may
appear in any position, i.e. '-m "start" - "end"' will
send 3 messages out of which the second one is read
from stdin. '-' may appear only once overall in all
arguments.
-i IMAGE [IMAGE ...], --image IMAGE [IMAGE ...]
Send this image. This option can be used multiple
times to send multiple images. First images are sent,
then text messages are sent. If you want to feed an
image into matrix-commander via a pipe, via stdin,
then specify the special character '-'. If '-' is
specified as image file name, then the program will
read the image data from stdin. If your image file is
literally named '-' then use '\-' as file name in the
argument. '-' may appear in any position, i.e. '-i
image1.jpg - image3.png' will send 3 images out of
which the second one is read from stdin. '-' may
appear only once overall in all arguments. If the file
exists already, it is more efficient to specify the
file name than to pipe the file through stdin.
-a AUDIO [AUDIO ...], --audio AUDIO [AUDIO ...]
Send this audio file. This option can be used multiple
times to send multiple audio files. First audios are
sent, then text messages are sent. If you want to feed
an audio into matrix-commander via a pipe, via stdin,
then specify the special character '-'. See
description of '-i' to see how '-' is handled.
-f FILE [FILE ...], --file FILE [FILE ...]
Send this file (e.g. PDF, DOC, MP4). This option can
be used multiple times to send multiple files. First
files are sent, then text messages are sent. If you
want to feed a file into matrix-commander via a pipe,
via stdin, then specify the special character '-'. See
description of '-i' to see how '-' is handled.
-e MATRIX_JSON_OBJECT [MATRIX_JSON_OBJECT ...], --event MATRIX_JSON_OBJECT [MATRIX_JSON_OBJECT ...]
Send an event that is formatted as a JSON object as
specified by the Matrix protocol. This allows the
advanced user to send additional types of events such
as reactions, send replies to previous events, or edit
previous messages. Specifications for events can be
found at https://spec.matrix.org/unstable/proposals/.
This option can be used multiple times to send
multiple events. First events are sent, then text
messages are sent. If you want to feed an event into
matrix-commander via a pipe, via stdin, then specify
the special character '-'. See description of '-i' to
see how '-' is handled. See tests/test-event.sh for
examples.
-w, --html Send message as format "HTML". If not specified,
message will be sent as format "TEXT". E.g. that
allows some text to be bold, etc. Only a subset of
HTML tags are accepted by Matrix.
-z, --markdown Send message as format "MARKDOWN". If not specified,
message will be sent as format "TEXT". E.g. that
allows sending of text formatted in MarkDown language.
-k, --code Send message as format "CODE". If not specified,
message will be sent as format "TEXT". If both --html
and --code are specified then --code takes priority.
This is useful for sending ASCII-art or tabbed output
like tables as a fixed-sized font will be used for
display.
-p SEPARATOR, --split SEPARATOR
If set, split the message(s) into multiple messages
wherever the string specified with --split occurs.
E.g. One pipes a stream of RSS articles into the
program and the articles are separated by three
newlines. Then with --split set to "\n\n\n" each
article will be printed in a separate message. By
default, i.e. if not set, no messages will be split.
--config CONFIG Location of a config file. By default, no config file
is used. If this option is provided, the provided file
name will be used to read configuration from. Not
implemented.
--proxy PROXY Optionally specify a proxy for connectivity. By
default, i.e. if this option is not set, no proxy is
used. If this option is used a proxy URL must be
provided. The provided proxy URL will be used for the
HTTP connection to the server. The proxy supports
SOCKS4(a), SOCKS5, and HTTP (tunneling). Examples of
valid URLs are "http://10.10.10.10:8118" or
"socks5://user:password@127.0.0.1:1080". URLs with
"https" or "socks4a" are not valid. Only "http",
"socks4" and "socks5" are valid.
-n, --notice Send message as notice. If not specified, message will
be sent as text.
--encrypted Send message end-to-end encrypted. Encryption is
always turned on and will always be used where
possible. It cannot be turned off. This flag does
nothing as encryption is turned on with or without
this argument. This flag exists only for historic
reasons. In some specific case encryption can be
disabled, please see --plain.
-l [LISTEN_TYPE], --listen [LISTEN_TYPE]
The --listen option takes one argument. There are
several choices: "never", "once", "forever", "tail",
and "all". By default, --listen is set to "never". So,
by default no listening will be done. Set it to
"forever" to listen for and print incoming messages to
stdout. "--listen forever" will listen to all messages
on all rooms forever. To stop listening "forever", use
Control-C on the keyboard or send a signal to the
process or service. The PID for signaling can be found
in a PID file in directory "/home/user/.run". "--
listen once" will get all the messages from all rooms
that are currently queued up. So, with "once" the
program will start, print waiting messages (if any)
and then stop. The timeout for "once" is set to 10
seconds. So, be patient, it might take up to that
amount of time. "tail" reads and prints the last N
messages from the specified rooms, then quits. The
number N can be set with the --tail option. With
"tail" some messages read might be old, i.e. already
read before, some might be new, i.e. never read
before. It prints the messages and then the program
stops. Messages are sorted, last-first. Look at --tail
as that option is related to --listen tail. The option
"all" gets all messages available, old and new. Unlike
"once" and "forever" that listen in ALL rooms, "tail"
and "all" listen only to the room specified in the
credentials file or the --room options.
-t [NUMBER], --tail [NUMBER]
The --tail option reads and prints up to the last N
messages from the specified rooms, then quits. It
takes one argument, an integer, which we call N here.
If there are fewer than N messages in a room, it reads
and prints up to N messages. It gets the last N
messages in reverse order. It print the newest message
first, and the oldest message last. If --listen-self
is not set it will print less than N messages in many
cases because N messages are obtained, but some of
them are discarded by default if they are from the
user itself. Look at --listen as this option is
related to --tail.
-y, --listen-self If set and listening, then program will listen to and
print also the messages sent by its own user. By
default messages from oneself are not printed.
--print-event-id If set and listening, then 'matrix-commander' will
print also the event id for each received message or
other received event. If set and sending, then
'matrix-commander' will print the event id of the sent
message or the sent object (audio, file, event) to
stdout. Other information like room id and reference
to what was sent will be printed too. For sending this
is useful, if after sending the user wishes to perform
further operations on the sent object, e.g.
redacting/deleting it after an expiration time, etc.
--download-media [DOWNLOAD_MEDIA]
If set and listening, then program will download
received media files (e.g. image, audio, video, text,
PDF files). media will be downloaded to local
directory. By default, media will be downloaded to is
"./media/". You can overwrite default with your
preferred directory. If media is encrypted it will be
decrypted and stored decrypted. By default media files
will not be downloaded.
-o, --os-notify If set and listening, then program will attempt to
visually notify of arriving messages through the
operating system. By default there is no notification
via OS.
--set-device-name DEVICE_NAME
Set or rename the current device to the device name
provided. Send, listen and verify operations are
allowed when renaming the device.
--set-display-name DISPLAY_NAME
Set or rename the display name for the current user to
the display name provided. Send, listen and verify
operations are allowed when setting the display name.
Do not confuse this option with the option '--get-
room-info' which gets the room display name, not the
user display name.
--get-display-name Get the display name of matrix-commander (itself), or
of one or multiple users. Specify user(s) with the
--user option. If no user is specified get the display
name of itself. Send, listen and verify operations are
allowed when getting display name(s). Do not confuse
this option with the option '--get-room-info' which
gets the room display name, not the user display name.
--set-presence PRESENCE_TYPE
Set presence of matrix-commander to the given value.
Must be one of these values: “online”, “offline”,
“unavailable”. Otherwise an error will be produced.
--get-presence Get presence of matrix-commander (itself), or of one
or multiple users. Specify user(s) with the --user
option. If no user is specified get the presence of
itself. Send, listen and verify operations are allowed
when getting presence(s).
--upload FILE [FILE ...]
Upload one or multiple files to the content
repository. The files will be given a Matrix URI and
stored on the server. --upload allows the optional
argument --plain to skip encryption for upload. See
tests/test-upload.sh for an example.
--download MXC_URI [MXC_URI ...]
Download one or multiple files from the content
repository. You must provide one or multiple Matrix
URIs (MXCs) which are strings like this
'mxc://example.com/SomeStrangeUriKey'. If found they
will be downloaded, decrypted, and stored in local
files. If file names are specified with --file-name
the downloads will be saved with these file names. If
--file-name is not specified the original file name
from the upload will be used. If neither specified nor
available on server, then the file name of last resort
'mxc-<mxc-id>' will be used. If a file name in --file-
name contains the placeholder __mxc_id__, it will be
replaced with the mxc-id. If a file name is specified
as empty string in --file-name, then also the name
'mxc-<mxc-id>' will be used. By default, the upload
was encrypted so a decryption dictionary must be
provided to decrypt the data. Specify one or multiple
decryption keys with --key-dict. If --key-dict is not
set, not decryption is attempted; and the data might
be stored in encrypted fashion, or might be plain-text
if the --upload skipped encryption with --plain. See
tests/test-upload.sh for an example.
--delete-mxc MXC_URI [MXC_URI ...]
Delete one or multiple objects (e.g. files) from the
content repository. You must provide one or multiple
Matrix URIs (MXC) which are strings like this
'mxc://example.com/SomeStrangeUriKey'. Alternatively,
you can just provide the MXC id, i.e. the part after
the last slash. If found they will be deleted from the
server database. In order to delete objects one must
have server admin permissions. Having only room admin
permissions is not sufficient and it will fail. Read
https://matrix-org.github.io/synapse/latest/usage/admi
nistration/admin_api/ for learning how to set server
admin permissions on the server. Alternatively, and
optionally, one can specify an access token which has
server admin permissions with the --access-token
argument. See tests/test-upload.sh for an example.
--delete-mxc-before TIMESTAMP [TIMESTAMP ...]
Delete objects (e.g. files) from the content
repository that are older than a given timestamp. It
is the timestamp of last access, not the timestamp
when the file was created. Additionally you can
specify a size in bytes to indicate that only files
older than timestamp and larger than size will be
deleted. You must provide a timestamp of the following
format: 'DD.MM.YYYY HH:MM:SS' like '20.01.2022
19:38:42' for January 20, 2022, 7pm 38min 42sec. Files
that are still used in image data (e.g user profile,
room avatar) will not be deleted from the server
database. In order to delete objects one must have
server admin permissions. Having only room admin
permissions is not sufficient and it will fail. Read
https://matrix-org.github.io/synapse/latest/usage/admi
nistration/admin_api/ for learning how to set server
admin permissions on the server. Alternatively, and
optionally, one can specify an access token which has
server admin permissions with the --access-token
argument. See tests/test-upload.sh for an example.
--joined-rooms Print the list of joined rooms. All rooms that you are
a member of will be printed, one room per line.
--joined-members ROOM [ROOM ...]
Print the list of joined members for one or multiple
rooms. If you want to print the joined members of all
rooms that you are member of, then use the special
character '*'.
--mxc-to-http MXC_URI [MXC_URI ...]
Convert one or more matrix content URIs to the
corresponding HTTP URLs. The MXC URIs to provide look
something like this
'mxc://example.com/SomeStrangeUriKey'. See tests/test-
upload.sh for an example.
--devices, --get-devices
Print the list of devices. All device of this account
will be printed, one device per line.
--discovery-info Print discovery information about current homeserver.
Note that not all homeservers support discovery and an
error might be reported.
--login-info Print login methods supported by the homeserver. It
prints one login method per line.
--content-repository-config
Print the content repository configuration, currently
just the upload size limit in bytes.
--rest REST_METHOD DATA URL [REST_METHOD DATA URL ...]
Use the Matrix Client REST API. Matrix has several
extensive REST APIs. With the --rest argument you can
invoke a Matrix REST API call. This allows the user to
do pretty much anything, at the price of not being
very convenient. The APIs are described in
https://matrix.org/docs/api/,
https://spec.matrix.org/latest/client-server-api/,
https://matrix-org.github.io/synapse/latest/usage/admi
nistration/admin_api/, etc. Each REST call requires
exactly 3 arguments. So, the total number of arguments
used with --rest must be a multiple of 3. The argument
triples are: (a) the method, a string of GET, POST,
PUT, DELETE, or OPTIONS. (b) a string containing the
data (if any) in JSON format. (c) a string containing
the URL. All strings must be UTF-8. There are a few
placeholders. They are: __homeserver__ (like
https://matrix.example.org), __hostname__ (like
matrix.example.org), __access_token__, __user_id__
(like @mc:matrix.example.com), __device_id__, and
__room_id__. If a placeholder is found it is replaced
with the value from the local credentials file. An
example would be: --rest 'GET' ''
'__homeserver__/_matrix/client/versions'. If there is
no data, i.e. data (b) is empty, then use '' for it.
Optionally, --access-token can be used to overwrite
the access token from credentials (if needed). See
tests/test-rest.sh for an example.
--set-avatar AVATAR_MXC
Set the avatar MXC resource used by matrix-commander.
Provide one MXC URI that looks like this
'mxc://example.com/SomeStrangeUriKey'.
--get-avatar [GET_AVATAR ...]
Get the avatar MXC resource used by matrix-commander,
or one or multiple other users. Specify zero or more
user ids. If no user id is specified, the avatar of
matrix-commander will be fetched. If one or more user
ids are given, the avatars of these users will be
fetched. As response both MXC URI as well as URL will
be printed.
--get-profile [USER ...]
Get the user profile used by matrix-commander, or one
or multiple other users. Specify zero or more user
ids. If no user id is specified, the user profile of
matrix-commander will be fetched. If one or more user
ids are given, the user profiles of these users will
be fetched. As response display name and avatar MXC
URI as well as possible additional profile information
(if present) will be printed. One line per user will
be printed.
--get-room-info [ROOM ...]
Get the room information such as room display name,
room alias, room creator, etc. for one or multiple
specified rooms. The included room 'display name' is
also referred to as 'room name' or incorrectly even as
room title. If one or more room are given, the room
informations of these rooms will be fetched. If no
room is specified, the room information for the
default room configured for matrix-commander is
fetched. Rooms can be given via room id (e.g.
'\!SomeRoomId:matrix.example.com'), canonical (full)
room alias (e.g. '#SomeRoomAlias:matrix.example.com'),
or short alias (e.g. 'SomeRoomAlias' or
'#SomeRoomAlias'). As response room id, room display
name, room canonical alias, room topic, room creator,
and room encryption are printed. One line per room
will be printed. Since either room id or room alias
are accepted as input and both room id and room alias
are given as output, one can hence use this option to
map from room id to room alias as well as vice versa
from room alias to room id. Do not confuse this option
with the options '--get-display-name' and '--set-
display-name', which get/set the user display name,
not the room display name.
--get-client-info Print information kept in the client, i.e. matrix-
commander. Output is printed in JSON format.
--has-permission ROOM_ID PERMISSION_TYPE [ROOM_ID PERMISSION_TYPE ...]
Inquire if user used by matrix-commander has
permission for one or multiple actions in one or
multiple rooms. Each inquiry requires 2 parameters:
the room id and the permission type. One or multiple
of these parameter pairs may be specified. For each
parameter pair there will be one line printed to
stdout. Values for the permission type are 'ban',
'invite', 'kick', 'notifications', 'redact', etc. See
https://spec.matrix.org/v1.2/client-server-
api/#mroompower_levels.
--import-keys IMPORT_KEYS IMPORT_KEYS
Import Megolm decryption keys from a file. This is an
optional argument. If used it must be followed by two
values. (a) a file name from which the keys will be
read. (b) a passphrase with which the file can be
decrypted with. The keys will be added to the current
instance as well as written to the database. See also
--export-keys.
--export-keys EXPORT_KEYS EXPORT_KEYS
Export all the Megolm decryption keys of this device.
This is an optional argument. If used it must be
followed by two values. (a) a file name to which the
keys will be written to. (b) a passphrase with which
the file will be encrypted with. Note that this does
not save other information such as the private
identity keys of the device.
--room-set-alias ALIAS ROOM [ALIAS ROOM ...], --room-put-alias ALIAS ROOM [ALIAS ROOM ...]
Add an alias to a room, or aliases to multiple rooms.
Provide pairs of arguments. In each pair, the first
argument must be the alias you want to assign to the
room given via room id in the second argument of the
pair. E.g. the 4 arguments 'a1 r1 a2 r2' would assign
the alias 'a1' to room 'r1' and the alias 'a2' to room
'r2'. If you just have one single pair then the second
argument is optional. If just a single value is given
(an alias) then this alias is assigned to the default
room of matrix-commander (as found in credentials
file). In short, you can have just a single argument
or an even number of arguments forming pairs. You can
have multiple room aliases per room. So, you may add
multiple aliases to the same room. A room alias looks
like this: '#someRoomAlias:matrix.example.org'. Short
aliases like 'someRoomAlias' or '#someRoomAlias' are
also accepted. In case of a short alias, it will be
automatically prefixed with '#' and the homeserver
will be automatically appended. Adding the same alias
multiple times to the same room results in an error.
--room-put-alias is eqivalent to --room-set-alias.
--room-resolve-alias ALIAS [ALIAS ...]
Resolves a room alias to the corresponding room id, or
multiple room aliases to their corresponding room ids.
Provide one or multiple room aliases. A room alias
looks like this: '#someRoomAlias:matrix.example.org'.
Short aliases like 'someRoomAlias' or '#someRoomAlias'
are also accepted. In case of a short alias, it will
be automatically prefixed with '#' and the homeserver
from the default room of matrix-commander (as found in
credentials file) will be automatically appended.
Resolving an alias that does not exist results in an
error. For each room alias one line will be printed to
stdout with the result.
--room-delete-alias ALIAS [ALIAS ...]
Delete one or multiple rooms aliases. Provide one or
multiple room aliases. You can have multiple room
aliases per room. So, you may delete multiple aliases
from the same room or from different rooms. A room
alias looks like this:
'#someRoomAlias:matrix.example.org'. Short aliases
like 'someRoomAlias' or '#someRoomAlias' are also
accepted. In case of a short alias, it will be
automatically prefixed with '#' and the homeserver
from the default room of matrix-commander (as found in
credentials file) will be automatically appended.
Deleting an alias that does not exist results in an
error.
--get-openid-token [USER ...]
Get an OpenID token for matrix-commander, or for one
or multiple other users. It prints an OpenID token
object that the requester may supply to another
service to verify their identity in Matrix. See
http://www.openid.net/. Specify zero or more user ids.
If no user id is specified, an OpenID for matrix-
commander will be fetched. If one or more user ids are
given, the OpenID of these users will be fetched. As
response the user id(s) and OpenID(s) will be printed.
--room-get-visibility [ROOM ...]
Get the visibility of one or more rooms. Provide zero
or more room ids as arguments. If no argument is
given, then the default room of matrix-commander (as
found in credentials file) will be used. For each room
the visibility will be printed. Currently, this is
either the string 'private' or 'public'. As response
one line per room will be printed to stdout.
--room-get-state [ROOM ...]
Get the state of one or more rooms. Provide zero or
more room ids as arguments. If no argument is given,
then the default room of matrix-commander (as found in
credentials file) will be used. For each room the
state will be printed. The state is a long list of
events including events like 'm.room.create',
'm.room.encryption', 'm.room.guest_access',
'm.room.history_visibility', 'm.room.join_rules',
'm.room.member', 'm.room.power_levels', etc. As
response one line per room will be printed to stdout.
The line can be very long as the list of events can be
very large. To get output into a human readable form
pipe output through sed and jq as shown in an example
in tests/test-setget.sh.
--delete-device DEVICE [DEVICE ...]
Delete one or multiple devices. By default devices
belonging to matrix-commander will be deleted. If the
devices belong to a different user, use the --user
argument to specify the user, i.e. owner. Only exactly
one user can be specified with the optional --user
argument. Device deletion requires the user password.
It must be specified with the --password argument. If
the server uses only HTTP (and not HTTPS), then the
password can be visible to attackers. Hence, if the
server does not support HTTPS this operation is
discouraged.
--room-redact ROOM_ID EVENT_ID REASON [ROOM_ID EVENT_ID REASON ...], --room-delete-content ROOM_ID EVENT_ID REASON [ROOM_ID EVENT_ID REASON ...]
Strip information out of one or several events, e.g.
messages. Redact is used in the meaning of 'strip,
wipe, black-out', not in the meaning of 'edit'. This
action removes, deletes the content of an event while
not removing the event. You can wipe text from a
previous message, etc. Typical Matrix clients like
Element will delete messages, images and other objects
from the GUI once they have been redacted. So, --room-
redact is a way to delete a message, images, etc. The
content is wiped, the GUI deletes the message, but the
server keeps the event history. Note, while this
deletes from the client (GUI, e.g. Element), it does
not delete from the database on the server. So, this
call is not a way to clean up the server database.
Each redact (wipe, strip, delete) operation requires
exactly 3 arguments. The argument triples are: (a) the
room id. (b) the id of the event to be redacted. (c) a
string containing the reason for the redaction. Use ''
if you do not want to give a reason. So, the total
number of arguments used with --room-redact must be a
multiple of 3, but we also accept 2 in which case only
one redaction will be done without specifying a
reason. Event ids start with the dollar sign ($).
Depending on your shell, you might have to escape the
'$' to '\$'. --room-delete-content is an alias for
--room-redact. They can be used interchangeably.
--whoami Print the user id used by matrix-commander (itself).
One can get this information also by looking at the
credentials file.
--no-ssl Skip SSL verification. By default (if this option is
not used) the SSL certificate is validated for the
connection. But, if this option is used, then the SSL
certificate validation will be skipped. This is useful
for home-servers that have no SSL certificate. If used
together with the "--ssl-certificate" parameter, this
option is meaningless and an error will be raised.
--ssl-certificate SSL_CERTIFICATE
Use this option to use your own local SSL certificate
file. This is an optional parameter. This is useful
for home servers that have their own SSL certificate.
This allows you to use HTTPS/TLS for the connection
while using your own local SSL certificate. Specify
the path and file to your SSL certificate. If used
together with the "--no-ssl" parameter, this option is
meaningless and an error will be raised.
--file-name FILE_NAME [FILE_NAME ...]
Specify one or multiple file names for some actions.
This is an optional argument. Use this option in
combination with options like --download to specify
one or multiple file names. Ignored if used by itself
without an appropriate corresponding action.
--key-dict KEY_DICT [KEY_DICT ...]
Specify one or multiple key dictionaries for
decryption. One or multiple decryption dictionaries
are provided by the --upload action as a result. A
decryption dictionary is a string like this: "{'v':
'v2', 'key': {'kty': 'oct', 'alg': 'A256CTR', 'ext':
True, 'k': 'somekey', 'key_ops': ['encrypt',
'decrypt']}, 'iv': 'someiv', 'hashes': {'sha256':
'someSHA'}}". If you have a list of key dictionaries
and want to skip one, use the empty string.
--plain Disable encryption for a specific action. By default,
everything is always encrypted. Actions that support
this option are: --upload, --room-create, and --room-
dm-create. Rooms are by default created encrypted; to
overwrite that and to create a room with encryption
disabled use '--plain'. See the individual commands.
--separator SEPARATOR
Set a custom separator used for certain print outs. By
default, i.e. if --separator is not used, 4 spaces are
used as separator between columns in print statements.
You could set it to '\t' if you prefer a tab, but tabs
are usually replaced with spaces by the terminal. So,
that might not give you what you want. Maybe ' || ' is
an alternative choice.
--access-token ACCESS_TOKEN
Set a custom access token for use by certain actions.
It is an optional argument. By default --access-token
is ignored and not used. It is used by the --delete-
mxc, --delete-mxc-before, and --rest actions.
--password PASSWORD Specify a password for use by certain actions. It is
an optional argument. By default --password is ignored
and not used. It is used by '--login password' and '--
delete-device' actions. If not provided for --login
the user will be queried via keyboard.
--homeserver HOMESERVER_URL
Specify a homeserver for use by certain actions. It is
an optional argument. By default --homeserver is
ignored and not used. It is used by '--login' action.
If not provided for --login the user will be queried
via keyboard.
--device DEVICE_NAME Specify a device name, for use by certain actions. It
is an optional argument. By default --device is
ignored and not used. It is used by '--login' action.
If not provided for --login the user will be queried
via keyboard. If you want the default value specify
''. Multiple devices (with different device id) may
have the same device name. In short, the same device
name can be assigned to multiple different devices if
desired.
--sync SYNC_TYPE This option decides on whether the program
synchronizes the state with the server before a 'send'
action. Currently two choices are offered: 'full' and
'off'. Provide one of these choices. The default is
'full'. If you want to use the default, then there is
no need to use this option. If you have chosen 'full',
the full state, all state events will be synchronized
between this program and the server before a 'send'.
If you have chosen 'off', synchronization will be
skipped entirely before the 'send' which will improve
performance.
--output OUTPUT_TYPE This option decides on how the output is presented.
Currently offered choices are: 'text', 'json', 'json-
max', and 'json-spec'. Provide one of these choices.
The default is 'text'. If you want to use the default,
then there is no need to use this option. If you have
chosen 'text', the output will be formatted with the
intention to be consumed by humans, i.e. readable
text. If you have chosen 'json', the output will be
formatted as JSON. The content of the JSON object
matches the data provided by the matrix-nio SDK. In
some occassions the output is enhanced by having a few
extra data items added for convenience. In most cases
the output will be processed by other programs rather
than read by humans. Option 'json-max' is practically
the same as 'json', but yet another additional field
is added. The data item 'transport_response' which
gives information on how the data was obtained and
transported is also being added. For '--listen' a few
more fields are added. In most cases the output will
be processed by other programs rather than read by
humans. Option 'json-spec' only prints information
that adheres 1-to-1 to the Matrix Specification.
Currently only the events on '--listen' and '--tail'
provide data exactly as in the Matrix Specification.
If no data is available that corresponds exactly with
the Matrix Specification, no data will be printed. In
short, currently '--json-spec' only provides outputs
for '--listen' and '--tail'. All other arguments like
'--get-room-info' will print no output.
--version Print version information. After printing version
information program will continue to run. This is
useful for having version number in the log files.

Autocompletion
Tab completion is provided for shells (e.g. bash), courtesy of @mizlan).
Here is a sample snapshot of tab completion in action:
Performance and Speed
matrix-commanderis written in Python and hence rather on the slow side- It is not thread-safe. One cannot just simply run multiple instances at the same time. However, with very careful set-up one can run multiple instances, but that is not the target use case. See Issue #31.
- Where possible bundle several actions together into a single call.
For example if one wants to send 8 images, then it is significantly faster
to call
matrix-commanderonce with-ispecifying 8 images, than to callmatrix-commander8 times with one image each call. One needs to send 5 messages, 10 images, 5 audios, 3 PDF files and 7 events to the same user? Callmatrix-commanderonce, not 30 times. - If you are sending something, then try the
--sync offoption and see to what degree skipping the server sync for sending helps. - Avoid using room aliases. Instead use room ids. For each room alias the corresponding id must be retrieved from the server creating overhead.
For Developers
- Don't change tabbing, spacing, or formatting as file is automatically sorted, linted and formatted.
pylama:format=pep8:linters=pep8- first
isortimport sorter - then
flake8linter/formater - then
blacklinter/formater - line length: 79
- isort matrix_commander.py
- flake8 matrix_commander.py
- python3 -m black --line-length 79 matrix_commander.py
- There is a script called
lintmc.shinscriptsdirectory for that.
Semantic Versioning
A version number is defined by: MAJOR.MINOR.PATCH where
- MAJOR version changes when there is a incompatible API change
- MINOR version changes when there is added functionality in a backwards-compatible manner, and
- PATCH version changes when there are backwards-compatible bug fixes.
See also Issue #109 for a discussion on this topic.
Output written to stdout (e.g. results on --room-get-info) is considered part of the API. So, if there is added space this would cause a major version change even though only a "meaningless" character has changed.
Debugging and logging output written to stderr (e.g. debug statements,
info, warning, and errors) are not part of the API. So, if the
description of an error changes than this is only a patch.
You should not rely on anything written to stderr or parse stderr or
log files. An example line is:
2022-11-22 10:30:18,921: ERROR: matrix-commander: E123 Failed ....
The format is: date, level, module, number and description.
Only warnings and errors have the number part.
An effort is made to keep the first parts of these lines up to number
the same for warnings and errors, and only change description.
Output of --help can also change and should not be relied on, changes to it
are just a patch.
Some actions return a JSON event and these JSON objects might change as Matrix specifications change. This will not cause a version change in matrix-commander.

When preparing to package matrix-commander for NIX the question
came up if matrix-commander is GPL3Only or GPL3Plus. GPL3PLus was
deemed to be better. As such the license was changed from GPL3Only
to GPL3Plus on May 25, 2021. Versions before this date are licensed
under GPL3. Versions on or after this date are GPL3Plus, i.e.
GPL3 or later.
