NAME

       rake-compiler - Rake-based Ruby Extension (C, Java) task generator

DESCRIPTION

       The Rake-compiler is first and foremost a productivity tool for Ruby developers. It's goal
       is to make the busy developer's life easier by simplifying the building and  packaging  of
       Ruby extensions by simplifying code and reducing duplication.

       It  follows *convention over configuration* by advocating a standardized build and package
       structure for both C and Java based RubyGems.

       rake-compiler is the result of many hard-won  experiences  dealing  with  several  diverse
       RubyGems  that  provided  native  extensions  for  different  platforms and different user
       configurations in different  ways.  Details  such  as  differences  in  code  portability,
       differences  in code clarity, and differences in project directory structure often made it
       very difficult for newcomers to those RubyGems.

USAGE

       rake-compiler [-f rakefile] {options} targets...

OPTIONS

       --backtrace=[OUT]
              Enable full backtrace.  OUT can be stderr (default) or stdout.

       --comments
              Show commented tasks only

       --job-stats [LEVEL]
              Display job statistics. LEVEL=history displays a complete job list

       --rules
              Trace the rules resolution.

       --suppress-backtrace PATTERN Suppress backtrace lines matching regexp PATTERN. Ignored  if
              --trace is on.

       -A, --all
              Show all tasks, even uncommented ones (in combination with -T or -D)

       -B, --build-all
              Build all prerequisites, including those which are up-to-date.

       -D, --describe [PATTERN]
              Describe the tasks (matching optional PATTERN), then exit.

       -e, --execute CODE
              Execute some Ruby code and exit.

       -E, --execute-continue CODE
              Execute some Ruby code, then continue with normal task processing.

       -f, --rakefile [FILENAME]
              Use FILENAME as the rakefile to search for.

       -G, --no-system, --nosystem
              Use standard project Rakefile search paths, ignore system wide rakefiles.

       -g, --system
              Using system wide (global) rakefiles (usually '~/.rake/*.rake').

       -I, --libdir LIBDIR
              Include LIBDIR in the search path for required modules.

       -j, --jobs [NUMBER]
              Specifies the maximum number of tasks to execute in parallel. (default is number of
              CPU cores + 4)

       -m, --multitask
              Treat all tasks as multitasks.

       -n, --dry-run
              Do a dry run without executing actions.

       -N, --no-search, --nosearch
              Do not search parent directories for the Rakefile.

       -P, --prereqs
              Display the tasks and dependencies, then exit.

       -p, --execute-print CODE
              Execute some Ruby code, print the result, then exit.

       -q, --quiet
              Do not log messages to standard output.

       -r, --require MODULE
              Require MODULE before executing rakefile.

       -R, --rakelibdir RAKELIBDIR,
              Auto-import any .rake files in RAKELIBDIR. (default is 'rakelib')

       --rakelib

       -s, --silent
              Like --quiet, but also suppresses the 'in directory' announcement.

       -t, --trace=[OUT]
              Turn on invoke/execute tracing, enable full backtrace. OUT can be stderr  (default)
              or stdout.

       -T, --tasks [PATTERN]
              Display  the  tasks  (matching  optional PATTERN) with descriptions, then exit. -AT
              combination displays all of tasks contained no description.

       -v, --verbose
              Log message to standard output.

              Display the program version.

       -W, --where [PATTERN]
              Describe the tasks (matching optional PATTERN), then exit.

       -X, --no-deprecation-warnings
              Disable the deprecation warnings.
