Gitter

Gitter is a Git statistics tool. It can process multiple repositories and report statistics or commit traffic on them.

The repositories must be checked out in the local file system for Gitter to work.

How it looks like

Here is an image showing the commits per interval of the open source git repositories of Ansible and GoCD in 2017:

Features

The features of this Git statistics tool are:

• Quick.
• Multiple reports (see below).
• Can extract misc strings from the commit message, for example ticket numbers.

The command line options are listed here:

ERVAL | AUTHORS_COMMITS_PER_INTERVAL      
| DAYTIMES_PER_INTERVAL |                 
MESSAGE_PATTERN_PER_AUTHOR |

Reports

This section shows an overview of available reports (aka flavors in the options).

COMMITS_PER_AUTHOR

Shows the number of commits per project and per author.

COMMITS_PER_INTERVAL

Shows the number of commits per project and per interval.

AUTHORS_PER_INTERVAL

Shows which authors were active on which project in which interval. The author names are shortened to their initials.

In the following example the authors initials are taken. "Peter Huber" will have the initials "PH":

Please note that the abbreviation with name initials works best for a limited set of developers.

AUTHORS_COMMITS__PER_INTERVAL

Similar to AUTHORS_PER_INTERVAL, but also shows the number of commits per author.

In the following example the authors initials are taken. "Peter Huber" will have the initials "PH":

DAYTIMES_PER_INTERVAL

At which times do the commits happen every day?

MESSAGE_PATTERN_PER_AUTHOR

Matches a regular expression against each commit message and shows the resulting matches per author. This report is useful for extracting ticket numbers from commit messages and displaying them per project.

In the following example the issue numbers (#1234) of Github were taken as a pattern:

MESSAGE_PATTERN_PER_INTERVAL

Matches a regular expression against each commit message and shows the resulting matches per time interval. This report is useful for extracting ticket numbers from commit messages and displaying them per project.

In the following example the issue numbers (#1234) of Github were taken as a pattern:

PATCH_SCRIPT_SIZE_PER_INTERVAL

The patch script sizes in bytes per interval. Note that the overall first commit is not counted correctly at the moment.
