cobib 3.4.0

Console Bibliography

coBib

coBib is a simple, command-line based bibliography management tool. It is the result of the need for an easy-to-use alternative to full-blown reference managers like Mendeley or Zotero. As such it follows some basic design goals:

• plain-text database: which means you get full access and control over the database.
• git-integration: as a benefit of the above, you can keep track of your database through version control.
• centralized database, location-independent library: this means, that coBib only manages the database file in a centralized fashion but allows you to spread the actual contents of your library across the entire file system (this is the major different to papis).
• command-line and TUI support: all features are available through the command-line as well as a curses-based TUI.

Installation

For all common purposes you can install coBib via pip:

pip install cobib

Note: Use pip3 if you still have Python 2 installed.

If you would also like to install the man-page and (crude!) Zsh completion, you need to download the source code and do the following:

git clone https://gitlab.com/mrossinek/cobib
cd cobib
make install_extras

Arch Linux

coBib is packaged in the AUR.

• cobib
• cobib-git

Windows

Windows is only partially supported! This is due to the fact that Python under Windows does not ship with the curses module. Thus, you cannot run coBib's TUI on Windows. However, if you are using Windows 10 you should be able to install and use coBib's full functionality within the Linux subsystem.

Getting started

To get started, you must initialize the database:

cobib init

If you would like to enable the git-integration, you should run:

cobib init --git

and enable config.database.git (see also configuration).

Be sure to check out my Quickstart blog post for a more guided introduction compared to the following section!

Importing your library

coBib provides an import command through which you can easily import your library from another bibliography manager. For more details check out:

cobib import --help

So far, coBib knows how to import your library from Zotero by simply running:

cobib import --zotero

Check out the following command, the man page or the online documentation for more details:

cobib import --zotero -- --help

Usage

Adding new entries

You can now add new entries to your database (see also cobib.commands.add[^1]):

cobib add --bibtex some_biblatex_file.bib
cobib add --arxiv <some arXiv ID>
cobib add --doi <some DOI>
cobib add --isbn <some ISBN>

Note: when adding data from a .bib file, make sure that it is in the BibLaTex format!

Viewing your database and entries

You can view the contents of your database with (see also cobib.commands.list):

cobib list

You can show a specific entry with (see also cobib.commands.show):

cobib show <some entry label>

You can open an associated file of an entry with (see also cobib.commands.open):

cobib open <some entry label>

You can even search through your database with (see also cobib.commands.search):

cobib search "some text"

Editing your database

You can delete an entry with (see also cobib.commands.delete):

cobib delete <some entry label>

You can edit an entry manually with (see also cobib.commands.edit):

cobib edit <some entry label>

You can also apply simple modifications to multiple entries at once with (see also cobib.commands.modify):

cobib modify tags:private -- <some entry label> <another entry label> ...

Exporting your database

You can export your database with (see also cobib.commands.export):

cobib export --bibtex my_bibliography.bib
cobib export --zip my_library.zip

Integrated version control

If you have enabled the git-integration, you can undo and re-apply changes to your database with (see also cobib.commands.undo and cobib.commands.redo):

cobib undo
cobib redo

Getting help

Each subcommand provides additional help via:

cobib <subcommand> --help

and you can find extensive information in the online documentation (linked above) and the man-page:

man cobib

TUI

Finally, you can also use coBib's TUI for a more interactive experience (see also cobib.tui), by simply typing

cobib

Configuration

You can overwrite the default configuration by placing a config.py file in ~/.config/cobib/. The easiest way to get started with this file is by copying example.py or by using:

cobib _example_config > ~/.config/cobib/config.py

You can then modify it to your liking.

You may also specify a different config file at runtime by using the -c or --config command line argument.

Finally, be sure to take a look at the man page (man cobib) and/or the online documentation for more information.

Documentation

coBib's documentation is hosted here.

If you would like to generate a local version during development, you need to clone the source code, and install pdoc in order to generate it:

git clone https://gitlab.com/mrossinek/cobib.git
cd cobib
pip install pdoc
pdoc -d google -e cobib=https://gitlab.com/mrossinek/cobib/-/blob/master/src/cobib/ -t html -o docs src/cobib tests

You can then browse the documentation from docs/cobib.html.

History

I have started this project when I was looking into alternatives to popular reference managers such as Mendeley, which has more features than I use on a regular basis and does not allow me to work from the command line which is where I spent most of the time that I spent on the computer.

Hence, I have decided to make it my own task of implementing a simple, yet fast, reference manager. coBib is written in Python and uses a YAML file to store its bibliography in a plain text format.

  • this can be used for string or list concatenation and even number addition on numeric fields

Changed

• use file paths relative to user-home (achieved by replacing os.path with pathlib) (#69)
• the shell helper _list_tags has been renamed to _list_labels
• (DEV): the logging and zsh_helper modules have been relocated to the cobib.utils package
• + symbols will no longer be stripped from tags (this was a left-over artifact from pre-v1.0.0)

2.6.1 - 2021-02-05

Pypi: https://pypi.org/project/cobib/2.6.1/

Fixed

• TUI no longer crashes when aborting to quit (#64)

2.6.0 - 2020-12-31

  • will automatically track any changes done to the database file with git
  • must be enabled by setting the DATABASE/git option to True and running cobib init --git
  • Note, that you must have at least set a name and email in the git config!
• Undo/Redo commands to operate on git history of the database (#59,!23)
  • for obvious reasons these commands require the Git integration (see above) to be enabled
• the Prompt command inside of the TUI:
  • allows executing arbitrary CoBib CLI commands
  • the default key binding is :
• the Modify command: (#60,!24)
  • allows bulk modification of multiple entries in a <field>:<value> format
  • for now, this will always overwrite the field with the new value!

  • this should not have any visible effect to an end-user but may be relevant to developers

Fixed

• gracefully handle multiple terminal sizing issues with regards to popups (#58)
• catch messages on stdout during deletion from TUI
• added missing help strings to the TUI help menu

Removed

• The --force argument to the init command has now been removed (after being deprecated in v2.5.0).

Added

• support for multiple associated files (#42,!19)
• interactive menu when opening an entry with multiple associated files (!19)

Deprecated

• The --force argument to the init command has been deprecated. I don't think there is any benefit to providing the user the option to nuke their database file from the CLI. Instead, they can simply edit the file manually.

Fixed

2.3.0 - 2020-09-10

Pypi: https://pypi.org/project/cobib/2.3.0/

Added

• Logging functionality has been added. The verbosity level can be controlled via -v (INFO) and -vv (DEBUG). As soon as the TUI starts, all logging output is redirected to /tmp/cobib.log.
• Command line argument -l or --logfile can be used to specify the output path of the log. This will overwrite the /tmp/cobib.log location.
• the TUI/scroll_offset setting was added. It defaults to 3 and behaves similar to Vim's scrolloff setting.
• Configuration validation has been added. This extends the logging functionality to support more runtime debug information.
• popup window support: stdout and stderr messages are presented in a popup similarly to the help window

Changed

• -v command line argument now refers to --verbose rather than --version
• Performance of the add command has been improved by not refreshing the database when outside of the TUI.

Fixed

• bug when resizing causes the window width to become greater than the buffer width (#39)
• do not escape special characters in labels (#40)
• avoid special character encoding in file paths
