repostat

Python3-compatible Git repository analyser and HTML-report generator with nvd3 -driven interactive metrics visualisations.

Initially, a fork of gitstats tool.

Installation

Starting from v2.0.0, repostat is installable from PyPi under the name repostat-app. Installation should be as simple as:

pip3 install repostat-app

Newest and older versions

To install a development version with newest changes from repostat's github repository, the following command may be executed:
```
sudo pip3 install git+https://github.com/vifactor/repostat
```
This command installs repostat from HEAD of master branch.

To install repostat at specific tag or branch, use the following syntax

sudo pip3 install git+https://github.com/vifactor/repostat@<branch|tag>

NOTE: Versions prior to v2.0.0 have additional system-dependencies, e.g. gnuplot.

OS-specific requirements

Linux installation

python3-pip must be in the system and then installation via pip works fine.

Mac OS (Catalina) installation

Prior to installing repostat one needs to make sure to have right version of libgit2 in the system. This can be achieved

following pygit2 installation instructions
(not recommended) installing it via Homebrew

$ brew update
$ brew install libgit2

Then, install repostat via:

$ pip3 install repostat-app

NOTE:

Homebrew-way to install packages is slow and may break system dependencies.
repostat's CI for OSX builds libgit2 from source.

Windows installation

Once there is python v3.6+ in the system path, repostat can be installed via:

python -m pip install repostat-app

NOTE: On Windows 10+, symlink to general.html is not generated, when repostat launched by an unprivileged user.

Usage

repostat [--help] [--version] [--config_file CONFIG_FILE_PATH]
                 git_repository_path report_output_path

Run repostat --help for details.

Configuration file

A report can be customized using a JSON settings file. The file is passed using the --config-file option as follows:

repostat --config-file <path_to_config.json> <repo_path> <out_path>

Configuration file might contain following fields (all are optional):

{
    "max_domains": 10,
    "max_authors": 7,
    "max_plot_authors_count": 10,
    "max_authors_of_months": 6,
    "authors_top": 5,
    "colormap": "classic",
    "max_recent_tags": -1,
    "orphaned_extension_count": 2,
    "time_sampling": "W"
}

Detailed information about role of the fields is below.

Authors page configuration

These values are usually adjusted to accommodate projects with various number of contributors and activity levels, to avoid showing too much or too little information.

max_domains: number of e-mail domains to show in author stats
max_authors: number of authors in the "top authors" table (other authors are listed without detailed stats)
max_plot_authors_count: number of authors to include in plots in "Authors"-page (rest of the authors will be grouped as "Others").
max_authors_of_months: number of months for which "author of the month" should be displayed
authors_top: number of authors to show for each month/year in the author of month/year list
orphaned_extension_count: max file extension count to be considered as orphaned and displayed in report in the corresponding category (default: 0, i.e. all extensions are displayed)

Colorscheme configuration

The colors of the thread "heat maps" tables in the activity page can be customized using the "colormap" option. The allowed values are:

classic: (default) uses shades of red only, like gitstats
plasma: uses the "plasma" colormap
viridis: uses the "viridis" colormap
clrscc: uses a selection of colors from https://clrs.cc/

History plots sampling

is controlled by "time_sampling" field in configuration file and defines how timeseries , e.g. number of files over a repository history, are sampled. By default, weekly-sampling is used. For old repositories one might want to increase that value to month or even quarter. Accepted values for "time_sampling" are the Pandas' Offset aliases

Tags rendering

Some git repositories contain thousands of tags most of which are not worth to check. Since v.1.3.0 there is a possibility to limit the number of tags displayed in "Tags" tab of the HTML report or even hide the tab.

The feature is controlled by "max_recent_tags" field

If JSON file has following content { [...], "max_recent_tags": 8 }, the report will contain the 8 most recent tags in "Tags" page. Setting the field max_recent_tags to zero will not render "Tags" page at all. If no such field is provided in JSON settings, the report will contain a "Tags" page with all tags in the analysed repository.

Additional features

Mailmap

Starting from v1.1.2+ repostat supports git mailmap. Two things are required in order to make the feature working:

have pygit2 v.0.28+ installed
create and fill .mailmap file (e.g. in the root of your repository)

Relocatable reports

By default, images, css- and js-files required for html report rendering do not get copied to a report directory. Html pages contain absolute paths to assets located in repostat's package installation directory.

Starting from v.1.0.x, the --copy-assets command-line option forces program to copy assets to generated report and embed relative paths in the generated html-files.
