Xcode has a bad habit of adding trailing whitespace to code, which is a pet
|
|
peeve of mine. It introduces irrelevant changes into diffs and is particularly
|
|
glaring when commiting code with [GitX], which highlights it in red. In [TextMate]
|
|
and now [Vico] I have bound the strip trailing whitespace in current document
|
|
action to ⌃⌥⌘S (control-option-command-s). This makes it quick and easy.
|
|
Xcode makes adding these types of actions a bit harder but I came up with a
|
|
solution that uses the Behaviours functionality in Xcode 4. This is how I did
|
|
it:
|
|
|
|
[GitX]: http://gitx.frim.nl/
|
|
[Vico]: http://www.vicoapp.com/
|
|
[TextMate]: http://macromates.com/
|
|
|
|
Create a shell script that invokes `sed` on each git tracked file that is
|
|
modified. Since Xcode doesn't tell the script what the current file was and
|
|
I didn't want to run sed over every file every time, processing tracked files
|
|
with modifications was the best solution I could come up with. Note that the
|
|
script also only prcocesses `.m` and `.h` files. I have my copy of the script
|
|
in `~/Documents/strip.sh`, be sure to give it the execute permission.
|
|
|
|
<script src="https://gist.github.com/1175182.js?file=strip.sh"></script>
|
|
|
|
Next you need to add a behaviour to Xcode. Go to the Xcode preferences and
|
|
click the Behaviours section, then click the + button. Name the behaviour and
|
|
give it a keyboard shortcut. In the right pane check Run and choose the script
|
|
you saved above. That's it. Now you can kill off that nasty whitespace with
|
|
ease.
