SVN Tricks

Aliases

Stick the following lines in your .bash_profile to get svn_modified, svn_new, and svn_status commands:

alias svn_modified="svn status | grep -v moc | grep -v pyousia | grep -v Makefile | grep -v objects_ | grep \"M \""

alias svn_new="svn status | grep -v moc | grep -v pyousia | grep -v Makefile | grep -v objects_ | grep \"? \""

alias svn_status="svn_new; svn_modified"

Grep

wcgrep automatically excludes .svn entries from a recursive search.

Mac OS X

function wcgrep {
    grep -R $1 * | grep -v .svn | grep -v "~" | grep -v ".pyc" | grep -v Binary
}

# 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 use the command named grep.
# 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.
