# Licensed under the terms subversion ships under or GPLv2.
# Useful for greping in a subversion working copy.
# Essentially it behaves the same way your grep command does (in fact it
# ultimately calls the grep command on your path) with a few exceptions.
# Ignores the subversion admin directories (.svn) and vi(m) backup files.
# Recursive is always on with or without -r.
# Always print filename and line numbers.
# Ignores binary files.
# If no path is given the current working directory is searched not stdin.
# Other than that it will take any parameter or pattern your standard grep
# does.
#
# This script requires GNU findutils and by default GNU grep (though that
# can be changed with environment variables).
#
# There are three environment variables you can set that modify the default
# behavior:
#
# WCGREP_GREP Controls what command is used for the grep command.
# If unset or null wcgrep will check if ggrep (GNU grep)
# is available and use it; if "ggrep" could not be found
# in the path, "grep" will be used.
# WCGREP_GREPARGS Controls what arguments are always passed to the grep
# command before the arguments given on the command line.
# If unset or null it defaults to -HnI (always print file
# names, line numbers and ignore binary files). If you wish
# to set no default args set the variable to a space (" ").
# WCGREP_IGNORE Controls what files are ignored by the grep command.
# This is a regex that is passed to the find command with
# -regex so see find's man page for details. If unset or
# null defaults to '.*~$\|.*/\.svn\(/\|$\)', which will
# ignore vim backup files and subversion admin dirs.
grepargs=
pattern=
# When loop completes, $@ should contain only list of paths to traverse.
# If empty, set it to "." for compatibility (path list is not optional everywhere).
# This way we can use "$@" feature when calling find(1).
#
# XXX The grepargs handling is broken, unlike the handling of path arguments.
