PROGRAM:
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.
