COGS Operates Google Sheets
Project description
COGS Operates Google Sheets
WARNING This project is work in progress.
COGS takes a set of TSV files on your local file system and allows you to edit them using Google Sheets.
Setup
COGS is distributed on PyPI. To install:
pip install ontodev-cogs
To see a list of all commands:
cogs -h
For help with a specific command:
cogs [command] -h
Development
For local development on Unix (Linux or macOS), we suggest these install instructions:
$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip install -r requirements.txt
$ pip install -e .
$ cogs -h
Overview
Since COGS is designed to synchronize local and remote sets of tables,
we try to follow the familiar git
interface and workflow:
cogs init
creates a.cogs/
directory to store configuration data and creates a spreadsheet for the projectcogs add foo.tsv
starts tracking thefoo.tsv
table as a sheetcogs rm foo.tsv
stops tracking thefoo.tsv
table as a sheetcogs push
pushes changes to local sheets to the project spreadsheetcogs fetch
fetches the data from the spreadsheet and stores it in.cogs/
cogs ls
shows a list of currently-tracked sheet names and their local namescogs status
summarizes the differences between tracked files and their copies in.cogs/
cogs diff
shows detailed differences between local files and the spreadsheetcogs merge
overwrites local files with the data from the spreadsheet, if they have changedcogs pull
combines fetch and merge
There are some other commands that do not correspond to any git
actions:
cogs apply
applies attributes from standardized tables to one or more sheetscogs clear
removes formatting, notes, and/or data validation rules from one or more sheetscogs connect
initiates a new COGS project by connecting an existing Google Spreadsheetcogs delete
destroys the spreadsheet and configuration data, but leaves local files alonecogs mv foo.tsv bar.tsv
updates the path to the local version of a spreadsheet fromfoo.tsv
tobar.tsv
cogs open
displays the URL of the spreadsheetcogs share
shares the spreadsheet with specified users
There is no step corresponding to git commit
.
We recommend running cogs push
after updating a local tracked sheet to keep the remote sheets in sync.
When updating a remote sheet, we recommend the following to keep the local sheets in sync:
cogs pull
Logging
To print info-level logging messages (error and critical level messages are always printed), run any command with the -v
/--verbose
flag:
cogs [command & opts] -v
Otherwise, most commands succeed silently.
Definitions
- Spreadsheet: the remote Google Sheets spreadsheet - each COGS project corresponds to one spreadsheet
- Sheet: a tab in the spreadsheet - each sheet corresponds to one local TSV or CSV table
- Remote: data from Google Sheets
- Local: data from your local working directory
- Cached: data stored in
.cogs/
which is fetched from the remote spreadsheet - Format: the format applied to a cell in a sheet (e.g., background color, font family, etc.)
- Note: a note (a.k.a. comment) on a cell that appears when hovered over in the sheet
Commands
add
Running add
will begin tracking a local TSV or CSV table. The table details (path, name/title, and description) get added to .cogs/sheet.tsv
.
cogs add [path] -d "[description]"
The -d
/--description
is optional. You can also specify a number of rows and or columns to freeze:
cogs add [path] -r [freeze_row] -c [freeze_column]
If you specify -r 2 -c 1
, then the first two rows and the first column will be frozen once the sheet is pushed to the remote Google Spreadsheet. If these options are not included, no rows or columns will be frozen.
By default, the sheet title is created from the path (e.g. tables/foo.tsv
will be named foo
). If a sheet with this title already exists in the project, the task will fail.
You can also specify a sheet title that is different from the path with the -t
/--title
option:
cogs add [path] -t "[title]"
This does not immediately change the Google Sheet -- use cogs push
to push all tracked local tables to the project spreadsheet.
Adding an Ignored Sheet
By default, COGS ignores any untracked remote sheets. If you wish to start tracking a new remote sheet, you can do this by passing the sheet title to add
:
cogs add [title]
The default path for pulling changes from this newly-added sheet will be the current working directory (the same directory as .cogs/
is in) and will be a lowercase, space-replaced version of the title (e.g. My Sheet
becomes my_sheet.tsv
). If you already have a tracked sheet at this location, the date & time will be appended to the path (e.g., my_sheet_20200922_103045.tsv
for a sheet fetched at 10:30:45 on 2020/09/22). This path can be updated with cogs mv
.
You can also add all ignored sheets using the -a
/--all
flag:
cogs add --all
apply
Running apply
applies the details of one or more message tables or data validation tables to the spreadsheet as cell formatting and notes.
cogs apply [table1.tsv table2.tsv ...]
Message Tables
Message tables provide a standard table output for logging messages (info, warn, or error) that can be converted into formatting and notes in the spreadsheet using apply
. As long as the table follows the format described below, any type of message can be applied to the sheets. One example is the errors from ROBOT template.
These tables are applied to the sheets as formats and notes. The three levels of logging will be formatted with a black border and the following backgrounds:
- error: light red background
- warn/warning: light yellow background
- info: light blue background
The notes and formats will be added to any existing, but will take priority over the existing notes and formats.
These tables must have the following headers:
- table: name of the table that the problem occurs in
- cell: A1 format of problematic cell location
The following fields are optional:
- level: severity of the problem; error, warn, or info - if not included, this will default to "error"
- rule ID: an IRI or CURIE to uniquely identify the problem
- rule: descriptive name of the problem - this is converted to the cell note
- message: detailed instructions on how to fix the problem
- suggestion: a suggested value to replace the problematic value
The only required fields are table
and cell
. If no other fields are provided, the cell will be highlighted red with a note that says "ERROR". We strongly recommend using either a rule ID
or rule
to identify the message, and message
text to provide more details.
Data Valildation Tables
The data validation tables are applied to the sheets as data validation rules. These tables must have the following headers:
- table: name of the table to add data validation rules to
- range: A1 format of the cell or range of cells to apply data validation rules to
- condition: the condition (see below) for the data validation rule
- value: the allowed value or values (see bellow)for the data validation rule
For example:
table | range | condition | value |
---|---|---|---|
Sheet1 | A2:A | TEXT_EQ | foo |
Sheet1 | B2:B | ONE_OF_LIST | foo, bar, baz |
For full descriptions of each condition type, please see Google Sheets API ConditionType.
Any value greater than one should be specified as a comma-separated list (e.g., for NUMBER_BETWEEN
, the value could be 1, 10
). For "0" values, leave the value
column empty.

clear
clear
removes applied attributes (either from apply
or manually added to the sheet remotely) from one or more sheets:
cogs clear [keyword] [sheet-title-1] [sheet-title-2] ...
The keyword must be one of:
- formats: sheet formatting
- notes: sheet notes
- validation: data validation rules
- all: formats, notes, and rules
After the keyword, you can supply zero or more sheet titles to remove attributes from. If no sheet titles are provided, the attribute(s) specified by the keyword will be removed from all sheets.
connect
connect
is similar to init
in that it creates a new COGS project in the current directory. Instead of creating a new Google Spreadsheet, though, it connects to an existing one that you have already created. In order to run connect
, you must not have an existing COGS project in the directory. We also recommend that you are the owner of the Spreadsheet you are connecting, as you will need to transfer ownership to the service account defined in your credentials.
cogs connect -k [spreadsheet-url-or-key] -c [path-to-credentials]
The --key
/-k
argument accepts either the full sheet URL or just the key. You can find the spreadsheet key in the URL of the Google Spreadsheet:
https://docs.google.com/spreadsheets/d/[SPREADSHEET-KEY]/edit#gid=0
As with init
, you may exclude the -c
argument if you have your credentials defined in the environment variable GOOGLE_CREDENTIALS
. Note that this variable must be the contents of the credentials file, not the path to the file.
After connecting to the existing spreadsheet, COGS will pause to ask you to share the Spreadsheet with the service email. It will provide a link to the sheet and the service email to share with. You can either give the service email "Editor" permissions, or transfer ownership.
To give "Editor" access:
- Open the Google Spreadsheet in your browser
- Click "Share" in the upper right corner
- Enter in the provided service email, uncheck "Nofity people", and click "Send"
- Return to the terminal and press ENTER to continue
To transfer ownership, click "Share" again and click the drop-down next to the service email and select "Make owner"
Please be aware that if you do not transfer ownership to the service account, cogs delete
will not work. All other commands will work with just "Editor" access. If you do transfer ownership, you can always transfer ownership back to yourself using the share
command.
delete
Running delete
reads the configuration data in .cogs/config.tsv
to retrieve the spreadsheet ID. This spreadsheet is deleted in Google Sheets and the .cogs
directory containing all project data is also removed. Any local TSV/CSV tables specified as sheets in the spreadsheet are left untouched.
cogs delete
diff
Running diff
will display all file changes between local and remote sheets after running cogs fetch
or after updating a local sheet (before pushing or pulling those changes).
cogs diff
By default, this will display all files with changes. If you wish to just see the changes for one or more paths, you can provide those paths:
cogs diff path1.tsv path2.tsv ...
diff
opens a responsive scrolling window. To scroll down, press the down arrow. To scroll up, press the up arrow (see all navigation below). For large files with many columns, you can also scroll to the right with the right arrow and back to the left with the left arrow.
The start of a diff for a sheet begins in bold with the file name (local and remote versions).
The displayed text below has formatting for changes between the local and remote sheets:
- Lines that have been removed from the remote version of the sheet are in red text and begin with
---
. - Lines that have been added to the local version of the sheet are in green text and begin with
+++
. - Lines that have been changed between the remote and local versions are in blue text and begin with
->
.
In cells with changed values, the cell is formatted as so:
old text -> new text
If a sheet has been newly created or deleted, these changes will not appear in diff
. Instead, use cogs status
.
To navigate the diff:
- ↑: move one line up
- ↓: move one line down
- →: move 20 characters right
- ←: move 20 characters left
q
: quitt
: go to top (first line)b
: go to bottom (last line)r
: go to rightmost characters (last column)l
: to to leftmost characters (first column)
fetch
Running fetch
will sync the local .cogs/
directory with all remote spreadsheet changes.
cogs fetch
This will download all sheets in the spreadsheet to that directory as {sheet-title}.tsv
- this will overwrite the existing sheets in .cogs/tracked/
, but will not overwrite the local versions specified by their path. Any sheets that have been added with add
and then pushed to the remote sheet with push
will be given their IDs in .cogs/sheet.tsv
.
.cogs/format.tsv
and .cogs/note.tsv
are also updated for any cell formatting or notes on cells, respectively. Each unique format is given a numerical ID and is stored as CellFormat JSON.
If a new sheet has been added to the Google spreadsheet, this sheet will be added to .cogs/sheet.tsv
as an "ignored" sheet. While it appears in the sheets, it will not be downloaded and has no local path. If you wish to add an ignored sheet to tracking, use cogs add
.
To sync the local version of sheets with the data in .cogs/
, run cogs merge
.
Note that if a sheet has been renamed remotely, the old sheet title will be replaced with the new sheet title. Any changes made to the local file corresponding to the old title will not be synced with the remote spreadsheet. Instead, once you run cogs merge
, a new sheet {new-sheet-title}.tsv
will appear in the current working directory (the same as if a new sheet were created). It is the same as if you were to delete the old sheet remotely and create a new sheet remotely with the same contents. Use cogs merge
to write the new path - the old local file will not be deleted.
init
Running init
creates a .cogs
directory containing configuration data. This also creates a new Google Sheets spreadsheet and stores the ID. Optionally, this new sheet may be shared with users.
cogs init -c [path-to-credentials] -t [project-title] -u [email] -r [role]
gspread
needs credentials to create a service account; you can either provide these with a file (-c [path]
) or with an environment variable (GOOGLE_CREDENTIALS
). The environment variable should be a string containing the contents of the credentials file. You must surround the contents with single quotes when setting this variable:
export GOOGLE_CREDENTIALS='{...}'
Options:
-t
/--title
: required, title of the project which will be used as the title of the Google spreadsheet-c
/--credentials
: path to Google API credentials in JSON format-u
/--user
: email of the user to share the sheet with (if a--role
is not specified, this user will be a writer)-r
/--role
: role of the user specified by--user
:writer
orreader
-U
/--users
: path to TSV containing emails and roles for multiple users (header optional)
The following files are created in the .cogs/
directory when running init
:
config.tsv
: COGS configuration, including the spreadsheet detailsformat.tsv
: Sheet ID, cell location or range, and format IDs (the format for each format ID is stored as a JSON dictionary in.cogs/formats.json
)note.tsv
: Sheet ID, cell location, and note for all notessheet.tsv
: Sheet names in spreadsheet and details (empty) - the sheets correspond to local tablesvalidation.tsv
: Data validation conditions
All other tasks will fail if a COGS project has not been initialized in the working directory.
ls
Running ls
displays a list of tracked sheet names and their local paths, even if the local path does not yet exist.
cogs ls
open
Running open
displays the URL of the spreadsheet.
cogs open
pull
Running pull
will sync local sheets with remote sheets. This combines cogs fetch
and cogs merge
into one step.
cogs pull
Note that if you make changes to a local sheet without running cogs push
, then run cogs pull
, the local changes will be overwritten.
push
Running push
will sync the spreadsheet with your local changes. This includes creating new sheets for any added tables (cogs add
) and deleting sheets for any removed tables (cogs rm
). Any changes to the local tables are also pushed to the corresponding sheets.
cogs push
This will also push all notes and formatting from .cogs/format.tsv
and .cogs/note.tsv
.
merge
Running merge
will sync local sheets with remote sheets after running cogs fetch
.
cogs merge
Note that if you make changes to a local sheet without running cogs push
, then run cogs fetch && cogs merge
, the local changes will be overwritten.
mv
Running mv
will update the path of a local sheet.
cogs mv [old_path] [new_path]
The old path must exist as a local file. It will be renamed to the new path during this process. If the basename of the new path (e.g., tables/foo.tsv
-> foo
) is already a tracked sheet, this command will fail as you cannot have two sheets with the same name.
We recommend running cogs push
after cogs mv
to keep the remote spreadsheet in sync.
rm
Running rm
will stop tracking one or more local sheets. This does not delete any local copies of sheets specified by their paths.
cogs rm [paths]
This does not delete the sheet(s) from the spreadsheet - use cogs push
to push all local changes to the remote spreadsheet and remove cached data about the sheet.
share
Running share
shares the spreadsheet with the specified user(s).
cogs share -r [reader-email] -w [writer-email]
There are three options:
-r
/--reader
: email of the user to give read access to-w
/--writer
: email of the user to give write access to-o
/--owner
: email of the user to transfer ownership to
Please be aware that transfering ownership of the Spreadsheet prevent COGS from performing any administrative actions (e.g., cogs delete
). If you do transfer ownership and wish to delete the project, you should simply remove the .cogs/
directory and then go online to Google Sheets and manually delete the project.
status
Running status
shows the difference between local and remote copies of tracked sheets.
cogs status
There are five kinds of statuses (note that any changes to the remote spreadsheet will not be accounted for until you run cogs fetch
)
- Modified locally: the sheet exists both locally and remotely (cached), but the local version has been edited since the last time
cogs fetch
orcogs push
were run- use
cogs diff [path]
to see details - use
cogs push
to sync local changes to remote version (overwriting any changes to remote not yet pulled)
- use
- Modified remotely: the sheet exists both locally and remotely, but
cogs fetch
has been run and returned a modified sheet since the last time the local version was edited- use
cogs diff [path]
to see details - use
cogs pull
to sync remote changes to local version (overwriting any changes to local not yet pushed)
- use
- Added locally: the sheet exists locally and has been added to tracking, but is not yet pushed to the remote spreadsheet
- use
cogs push
to add the sheet to the remote spreadsheet
- use
- Added remotely: the sheet exists remotely and has been added to tracking, but is not yet pulled to a local copy
- use
cogs pull
to add the sheet to locally
- use
- Removed locally: the sheet exists remotely but has been removed from tracking using
cogs rm
- use
cogs push
to remove the sheet from the remote spreadsheet
- use
- Removed remotely: the sheet exists locally but has been removed from remote spreadsheet
- use
cogs pull
to remove the sheet locally
