NAME

       pepper - Repository statistics and report tool

SYNOPSIS

       pepper [options] report [report options] [repository]

DESCRIPTION

       pepper is a command-line tool for retrieving statistics and generating reports from source code
       repositories. If invoked with valid options,it runs a lua(1) script given by report on the given
       repository, producing textual or graphical output.

       If the report argument doesn’t point to a lua(1) report script, a number of paths will be searched for a
       report with the given name (see ENVIRONMENT VARIABLES). Thus, the built-in reports can be launched by
       specifying their name only. Report-specific options can be passed as report options following the report
       script name. To retrieve a listing of options supported by the respective report, pass --help as
       described in OPTIONS.

       If no repository argument is present, the current directory will be used. Normally, the type of the
       repository is automatically detected, and an appropriate backend implementation will be selected. Some
       backends provide additional options, e.g. user authentication for remote repositories. Those options will
       be listed if you pass the --help flag as described in OPTIONS.

OPTIONS

       -?, -h, --help
           Print a nice help screen. If the command line includes a report script name or path, report options
           will be shown. Additionally, backend options will be shown for the selected repository or backend.

       -q, --quiet
           Set verbosity level to minimum. Only warnings and errors will be shown.

       -v, --verbose
           Increase verbosity level. Can be specified multiple times.

       --no-cache
           Neither read from nor write to the local revision cache.

       --list-reports
           List all reports that can be found in the current report search directories.

       --list-backends
           List all built-in repository backends.

       -bARG, --backend=ARG
           Force usage of backend named ARG. Use --list-backends to retrieve a list of all available backends.

REVISION CACHE

       pepper uses a local revision cache, located at $HOME/.pepper/cache. It contains meta-data and diffstats
       of revisions that have been requested in previous invocations of the program.

       If the program complains that your revision cache is invalid (probably because of abnormal program
       termination or power failure), please run the check_cache report to fix it and remove faulty revisions.

ENVIRONMENT VARIABLES

       PEPPER_REPORTS
           A colon-separated list of paths used to search for report scripts.

       PEPPER_CACHEDIR
           A path that overrides the default cache location.

EXAMPLES

       Let’s assume that the current directory is the repository of interest.

       pepper --list-reports
           This lists all reports in the current search path with their descriptions. The names from this
           listing can be used as the program’s report argument.

       pepper loc
           A classic "Lines of Code" graph will be generated, with the actual plotting done by gnuplot(1). If
           the user is running X11, a detached window containing the plot will be shown. Else, output in SVG
           format will be written to stdout. All meta-data and diffstats fetched during this session will be
           written to the revision cache.

       pepper loc --type=png --output=loc.png
           The same as above, now probably significantly faster because the revisions of interest are already
           cached. This time, a PNG image will be generated and written to "loc.png".

       pepper authors -n4 --tags="2.6.[0-9]*$"
           This time, the code contribution by the 4 busiest authors will be be plotted. Additionally, vertical
           tag marks will be show for all tags that look like releases (of the Linux kernel).

       pepper --username=user commit_counts --period=14d http://svn.example.org
           This generates a histogram of commit frequencies for the last 14 days. This time, a remote Subversion
           repository requiring authentication is being used. If a password is required, the program will prompt
           for it.

       pepper shortlog --branch=stable --summary
           This will print a simple commit summary from the "stable" branch to stdout, looking like
           git-shortlog(1).

CUSTOM REPORTS

       pepper provides an API for writing custom report scripts in lua(1). The pepper homepage at
       http://scm-pepper.sourceforge.net contains more information about this topic, including a scripting
       tutorial covering common tasks and an API reference manual.

EXIT STATUS

       0 on success, 1 on failure. Any error messages, warnings and progress will be printed to stderr.
