trac-attach.sh

#!/bin/sh

# A script that leverages Trac XML-RPC (I know, I know) to upload patches.
#
# This script is written specifically for the Mac, in that it reads from
# your keychain to derive your SVN password. You can change the SVN_PASS
# line below if you wanted to pull from ~/.svn/ or what not.
#
# Basic usage: `trac-attach.sh 12345` uploads a patch to ticket #12345,
# using the name 12345.diff. If there exists a 12345.diff, the patch is
# automatically incremented by Trac, as in 12345.2.diff, 12345.3.diff, etc.
#
# More advanced usage: `trac-attach.sh 12345.diff` uploads a patch to
# #12345, using the explicit name 12345.diff. This will *replace* an existing
# 12345.diff file. (The only time you should ever replace a patch is if
# you are correcting a file upload you only made moments ago.)
#
# Descriptions: The second argument allows for a description, as in:
# `trac-attach.sh 12345 "Does something cool."`. If a description is omitted
# and you are explicitly replacing an existing file, Trac automatically
# keeps the current description. (This is how the web interface works, too.)
#
# By Andrew Nacin, based on a script by Michael Adams. Mike gets credit for
# the pipe juggling. I get the blame for the rest.
