Installation
------------

Latest PyPI stable release
~~~~~~~~~~~~~~~~~~~~~~~~~~

|PyPI| |PyPI-Downloads| |Libraries-Dependents|

.. code:: sh

    pip install git-fame

Latest development release on GitHub
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

|GitHub-Status| |GitHub-Stars| |GitHub-Commits| |GitHub-Forks| |GitHub-Updated|

Pull and install:

.. code:: sh

    pip install "git+https://github.com/casperdcl/git-fame.git@main#egg=git-fame"

Latest Conda release
~~~~~~~~~~~~~~~~~~~~

|Conda-Forge|

.. code:: sh

    conda install -c conda-forge git-fame

Latest Snapcraft release
~~~~~~~~~~~~~~~~~~~~~~~~

|Snapcraft|

.. code:: sh

    snap install git-fame

Latest Docker release
~~~~~~~~~~~~~~~~~~~~~

|Docker|

.. code:: sh

    docker run --rm casperdcl/git-fame --help
    docker run --rm -v "/local/path/to/repository:/repo" -u "$(id -u)" casperdcl/git-fame

Register alias with git
~~~~~~~~~~~~~~~~~~~~~~~

On Windows, run:

.. code:: sh

    git config --global alias.fame "!python -m gitfame"

This is probably not necessary on UNIX systems.
If ``git fame`` doesn't work after restarting the terminal on Linux & Mac OS, try (with single quotes):

.. code:: sh

    git config --global alias.fame '!python -m gitfame'

Tab completion
~~~~~~~~~~~~~~

Optionally, systems with ``bash-completion`` can install tab completion
support. The
`git-fame_completion.bash `_
file needs to be copied to an appropriate folder.

On Ubuntu, the procedure would be:

.. code:: sh

    $ # Ensure completion works for `git` itself
    $ sudo apt-get install bash-completion

    $ # Install `git fame` completions
    $ sudo wget \
        https://raw.githubusercontent.com/casperdcl/git-fame/main/git-fame_completion.bash \
        -O /etc/bash_completion.d/git-fame_completion.bash

followed by a terminal restart.


Changelog
---------

The list of all changes is available on the Releases page: |GitHub-Status|


Usage
-----

.. code:: sh

    git fame              # If alias registered with git (see above)
    git-fame              # Alternative execution as python console script
    python -m gitfame     # Alternative execution as python module
    git-fame -h           # Print help

For example, to print statistics regarding all source files in a C++/CUDA
repository (``*.c/h/t(pp), *.cu(h)``), carefully handling whitespace and line
copies:

.. code:: sh

    git fame --incl '\.[cht][puh]{0,2}$' -twMC

It is also possible to run from within a python shell or script.

.. code:: python

    >>> import gitfame
    >>> gitfame.main(['--sort=commits', '-wt', '/path/to/my/repo'])

Finally, there is a live server for public GitHub repositories at `git-fame.cdcl.ml/gh/{owner}/{repo} `_.

Documentation
-------------

.. code::

    Usage:
      git-fame [--help | options] [...]

    Arguments:
             Git directory [default: ./].
                     May be specified multiple times to aggregate across
                     multiple repositories.

    Options:
      -h, --help     Print this help and exit.
      -v, --version  Print module version and exit.
      --branch=   Branch or tag [default: HEAD] up to which to check.
      --sort=   [default: loc]|commits|files|hours|months.
      --min=    Minimum value (of `--sort` key) to show [default: 0:int].
      --loc=   surv(iving)|ins(ertions)|del(etions)
                     What `loc` represents. Use 'ins,del' to count both.
                     defaults to 'surviving' unless `--cost` is specified.
      --excl=     Excluded files (default: None).
                     In no-regex mode, may be a comma-separated list.
                     Escape (\,) for a literal comma (may require \\, in shell).
      --incl=     Included files [default: .*]. See `--excl` for format.
      --since=  Date from which to check. Can be absolute (eg: 1970-01-31)
                      or relative to now (eg: 3.weeks).
      --until=  Date to which to check. See `--since` for format.
      --cost=  Include time cost in person-months (COCOMO) or
                       person-hours (based on commit times).
                       Methods: month(s)|cocomo|hour(s)|commit(s).
                       May be multiple comma-separated values.
                       Alters `--loc` default to imply 'ins' (COCOMO) or
                       'ins,del' (hours).
      -R, --recurse  Recursively find repositories & submodules within .
      -n, --no-regex  Assume  are comma-separated exact matches
                      rather than regular expressions [default: False].
                      NB: if regex is enabled ',' is equivalent to '|'.
      -s, --silent-progress    Suppress `tqdm` [default: False].
      --warn-binary  Don't silently skip files which appear to be binary data
                     [default: False].

      -M             Detect intra-file line moves and copies [default: False].
      -C             Detect inter-file line moves and copies [default: False].
      --ignore-rev=       Ignore changes made by the given revision
                               (requires `--loc=surviving`).
      --ignore-revs-file=   Ignore revisions listed in the given file
                               (requires `--loc=surviving`).

If multiple user names and/or emails correspond to the same user, aggregate
``git-fame`` statistics and maintain a ``git`` repository properly by adding a
`.mailmap file `_.

FAQs
~~~~

Options such as ``-w``, ``-M``, and ``-C`` can increase accuracy, but take
longer to compute.

Note that specifying ``--sort=hours`` or ``--sort=months`` requires ``--cost``
to be specified appropriately.

Note that ``--cost=months`` (``--cost=COCOMO``) approximates
`person-months `_ and should be used with
``--loc=ins``.

Meanwhile, ``--cost=hours`` (``--cost=commits``) approximates
`person-hours `_.

Extra care should be taken when using ``ins`` and/or ``del`` for ``--loc``
since all historical files (including those no longer surviving) are counted.
In such cases, ``--excl`` may need to be significantly extended.
On the plus side, it is faster to compute ``ins`` and ``del`` compared to
``surv``.


Examples
--------

Badges
~~~~~~

An SVG image for inclusion in README files and websites:

.. code:: sh

   git fame -wMC --format svg --min 1 > docs/authors.svg

Which can also be dynamically created for public GitHub repositories:

.. code:: md

   ![markdown-image](https://git-fame.cdcl.ml/gh/{owner}/{repo}?min=1)

CODEOWNERS
~~~~~~~~~~

Generating
`CODEOWNERS `_:

.. code:: sh

    # bash syntax function for current directory git repository
    owners(){
      for f in $(git ls-files); do
        # filename
        echo -n "$f "
        # author emails if loc distribution >= 30%
        git fame -esnwMC --incl "$f" | tr '/' '|' \
          | awk -F '|' '(NR>6 && $6>=30) {print $2}' \
          | xargs echo
      done
    }

    # print to screen and file
    owners | tee .github/CODEOWNERS

    # same but with `tqdm` progress for large repos
    owners \
      | tqdm --total $(git ls-files | wc -l) \
        --unit file --desc "Generating CODEOWNERS" \
      > .github/CODEOWNERS

Zenodo config
~~~~~~~~~~~~~

Generating `.zenodo.json `_:

.. code:: sh

    git fame -wMC --format json \
      | jq -c '{creators: [.data[] | {name: .[0]}]}' \
      | sed -r -e 's/(\{"name")/\n    \1/g' -e 's/:/: /g' \
      > .zenodo.json
