Wrapper to use OS X FileMerge when calling `svn diff`

config

### ~/.subversion/config
### Add this line to the [helpers] section

diff-cmd = ~/bin/svn-diffwrap.sh

svn-diffwrap.sh

#!/bin/sh
#
# Put this somewhere like ~/bin and make it executable
# `chmod +x ~/bin/svn-diffwrap.sh`

This is handy, thanks. I am using svn 1.7.10 and it doesn't seem to like the ~ in the config file. Any tips to get this working?

Edit: In the mean time, I've moved svn-diffwrap.sh into the .subversion directory, and now .subversion/config uses:

diff-cmd = svn-diffwrap.sh

Works as expected.

Awesome one, thanks!

Put quotes around $LEFT and $RIGHT on line 30 to handle filenames and paths with spaces:

$DIFF "$LEFT" "$RIGHT"

When I run your script via the terminal a la:

svn diff --diff-cmd ~/bin/svn-diffwrap.sh

It works fine.

But when I edit the ~/.subversion/config file, like you illustrated above, I get something like this:

computer:svn rstackhouse$ svn diff
Index: <file>
===================================================================
exec of '~/bin/svn-diffwrap.sh' failed: No such file or directorysvn: E200012: '~/bin/svn-diffwrap.sh' returned 255

Any idea why?

Any idea why?

Try using the full home directory path instead of ~.

Even I get this error when i do svn diff on terminal app (OS X 10.11.1)
exec of 'svn-diffwrap.sh' failed: No such file or directorysvn: E200012: 'svn-diffwrap.sh' returned 255

I moved the file to ~/.subversion folder (parallel to config) and updated ~/.subversion/config [helpers] with
diff-cmd=svn-diffwrap.sh

And, I made it executable using the mentioned command
$ls -l svn-diffwrap.sh
-rwxr-xr-x@ 1 staff 959 Nov 3 14:53 svn-diffwrap.sh

Any help please?

Ok, I found a solution for the error mentioned above (no such file or directory)...
diff-cmd=/Users/<YourUser>/.subversion/svn-diffwrap.sh

i.e. specify full path from '/' folder

@dtjm @iosappdeveloper This is a useful fix to specify svn-diffwrap. Saved me a ton of time. @changetip $1
