rake
RAKE(1) Ruby Programmers Reference Guide RAKE(1)NAME
rake -- Ruby Make
SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE]
[-r MODULE] [--rules] [variable=value] target ...
DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command.
Rake has the following features:
o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax
to worry about (is that a tab or a space?).
o Users can specify tasks with prerequisites.
o Rake supports rule patterns to synthesize implicit tasks.
o Flexible FileLists that act like arrays but know about manipulating file names and paths.
o A library of prepackaged tasks to make building rakefiles easier.
OPTIONS --version Display the program version.
-C
--classic-namespace
Put Task and FileTask in the top level namespace
-D [PATTERN]
--describe [PATTERN]
Describe the tasks (matching optional PATTERN), then exit.
-E CODE
--execute-continue CODE
Execute some Ruby code, then continue with normal task processing.
-G
--no-system
--nosystem Use standard project Rakefile search paths, ignore system wide rakefiles.
-I LIBDIR
--libdir LIBDIR Include LIBDIR in the search path for required modules.
-N
--no-search
--nosearch Do not search parent directories for the Rakefile.
-P
--prereqs Display the tasks and dependencies, then exit.
-R RAKELIBDIR
--rakelib RAKELIBDIR
--rakelibdir RAKELIBDIR
Auto-import any .rake files in RAKELIBDIR. (default is rakelib )
-T [PATTERN]
--tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit.
-e CODE
--execute CODE Execute some Ruby code and exit.
-f FILE
--rakefile FILE Use FILE as the rakefile.
-h
--help Prints a summary of options.
-g
--system Using system wide (global) rakefiles (usually ~/.rake/*.rake ).
-n
--dry-run Do a dry run without executing actions.
-p CODE
--execute-print CODE
Execute some Ruby code, print the result, then exit.
-q
--quiet Do not log messages to standard output.
-r MODULE
--require MODULE Require MODULE before executing rakefile.
-s
--silent Like --quiet, but also suppresses the 'in directory' announcement.
-t
--trace Turn on invoke/execute tracing, enable full backtrace.
-v
--verbose Log message to standard output (default).
--rules Trace the rules resolution.
