= Tips and Tricks for committers =

This page provides some useful hints how to work with our infrastructure. And they can also make your work a lot easier.

== Set svn properties automatically on new Portfiles ==

In the configuration for your Subversion client, enable automatic property setting and, for all files named Portfile, setting "svn:eol-style" to "native" and "svn:keywords" to "Id".  If you are not using Subversion's own svn command-line client, see its documentation.  For svn, you can make the appropriate changes by editing `~/.subversion/config` as follows:

{{{
...

[miscellany]
enable-auto-props = yes

...

[auto-props]
Portfile = svn:eol-style=native;svn:keywords=Id
}}}


== Apply patches directly from Trac URL ==

Add the following functions to your `.bashrc` in order to apply patches directly from Trac.
 
{{{
function trac-get {
    curl "$1?format=raw" -o $(basename $1)
}

function trac-patch {
    trac-get $1 || return
    patch -p0 < $(basename $1)
}
}}}

Use like this:
 1. Copy the URL to the patch from the Trac ticket page
 1. Switch to the ports directory
{{{
$ cd $(port dir foo)
}}}
 1. Apply the patch
{{{
$ trac-patch http://trac.macports.org/attachment/ticket/.../Portfile.diff
}}}
