Meld for OSX

This is a fork of Meld packaged and bundled for OSX. The original website for Meld is here https://meld.app. Minor work has been done to also integrate OSX menu and shortcuts, but the app is truly the original, excellent Meld.

:dvd: Download OSX dmg file

You may download any of the following versions. The 3.21.0 (r2) is the latest and the recommended version at this point.

:bulb:Tip: A lot of people are asking how to use this package as a git difftool/mergetool. Once installed, edit your ~/.gitconfig and add the following lines

[diff]
  tool = meld
[difftool]
  prompt = false
[difftool "meld"]
  trustExitCode = true
  cmd = open -W -a Meld --args \"$LOCAL\" \"$REMOTE\"
[merge]
  tool = meld
[mergetool]
  prompt = false
[mergetool "meld"]
  trustExitCode = true
  cmd = open -W -a Meld --args --auto-merge \"$LOCAL\" \"$BASE\" \"$REMOTE\" --output=\"$MERGED\"

:bulb:Tip: In order to open diff from command line/terminal, once installed, edit your ~/.zshrc or ~/.bash_profileand add the following lines 


    alias meld="open -W -a Meld $@"
You can use it like this: meld file1 file2 or meld folder1 folder2

:bulb:Tip: Meld OSX also understands/checks for the following environment variables. 

G_ENABLE_DIAGNOSTIC 0 or 1
GTK_THEME Adwaita or Adwaita:dark

The theme change can be done by changing the variable in the wrapper script 

sudo nano /Applications/Meld.app/Contents/MacOS/Meld

find the part that says 

environment = dict(os.environ, **{
    "DYLD_LIBRARY_PATH": ":".join([
        os.path.join(APPPATH, "Resources", "lib"),
        os.path.join(APPPATH, "Frameworks")
    ]),
    "LANG": LANG,
    "LC_ALL": LANG,
    "LC_CTYPE": LANG
})

and change it to 

environment = dict(os.environ, **{
    "DYLD_LIBRARY_PATH": ":".join([
        os.path.join(APPPATH, "Resources", "lib"),
        os.path.join(APPPATH, "Frameworks")
    ]),
    "LANG": LANG,
    "LC_ALL": LANG,
    "LC_CTYPE": LANG,
    "GTK_THEME":"Adwaita:dark"
})

and you'll have a fully dark meld..

Not Accepting Donations

I'm not currently accepting donations for the development of this fork. I just missed a proper implementation of Meld on Mac so I thought of creating this fork. If you want to donate, please donate to the original Meld project.

What is Meld?

Meld is a visual diff and merge tool targeted at developers. Meld helps you compare files, directories, and version controlled projects. It provides two- and three-way comparison of both files and directories, and has support for many popular version control systems.

Meld helps you review code changes and understand patches. It might even help you to figure out what is going on in that merge you keep avoiding.
