Meld is a great tool, and it can ease the pain of svn greatly. Unfortunately, until recently (not yet in version 1.3), it did not support a merge result file argument.
But now it does! (still experimental and not officially released)
So how to use it (under linux, or unix compatible systems):
Check if your Meld is > 1.3, if not,
Check the meld website to see if Meld > 1.3 is released and install it.
If you got Meld > 1.3 go ahead with "SVN Meld glue".
Fetch the Meld source and build it using:
If all went fine, you should be running Meld > 1.3 now. Close it off.
Start a text editor.
Write the following to a file named
With the text editor, edit
Locate this section:
Build Meld source
Fetch the Meld source and build it using:
cd ~/bin
git clone git://git.gnome.org/meld
cd meld
make
./bin/meld
If all went fine, you should be running Meld > 1.3 now. Close it off.
SVN Meld glue
Start a text editor.
Write the following to a file named
~/bin/svn-merge-meld
#!/usr/bin/env pythonChange the file permissions to +x:
# svn merge-tool python wrapper for meld
import sys
import subprocess
# path to meld ($ which meld)
meld = "~/bin/meld/bin/meld"

# the call to meld
cmd = [meld, mine, base, theirs, merged]
# Call meld, making sure it exits correctly
subprocess.check_call(cmd)
try:
main()
except Exception as e:
print "Oh noes, an error: %r" % e
if log:
f.write("Error: %r\n" % e)
sys.exit(-1)
chmod +x ~/bin/svn-merge-meld
With the text editor, edit

Usage
svn merge -r 14829:HEAD http://path/to/trunk my/branchPress
Select: (p) postpone, (df) diff-full, (e) edit, (r) resolved,
(mc) mine-conflict, (tc) theirs-conflict,
(s) show all options:
l-Enter
(the letter L) to fire up Meld.In this case:
- the left side is the change in my/branch
- the middle part is the merge result which you can edit
- the right side are the changes in the trunk
r-Enter
, and your done. (Almost) painless merging in svn!
