Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies meld-3.22.0.tar.xz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

About 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 supports many version control systems including Git, Mercurial, Bazaar, CVS and Subversion.

Meld helps you review code changes, understand patches, and makes enormous merge conflicts slightly less painful.

Meld is licensed under the GPL v2 or later.

You do not need to build Meld in order to run it. Meld can be run directly from this source directory by running:

$ bin/meld

Unix users should get Meld from their distribution package manager, or from Flathub.

Windows users should download the provided MSIs on the Meld home page.

OSX users can install Meld using Homebrew (or Macports, Fink, etc.), or there are unofficial native builds available from the Meld for OSX project.


Meld uses meson build system. Use the following commands to build Meld from the source directory:

$ meson _build
$ cd _build
$ ninja

You can then install Meld system-wide by running:

$ ninja install

A Windows installer can be built with command

C:\Python34\python.exe bdist_msi

which will create the file dist/Meld-VERSION-ARCH.msi.


It's easy to get started developing Meld. From a git checkout, just run bin/meld.

We also support development using Flatpak via GNOME Builder. At the Builder "Clone..." dialog, enter, and the default build + run development flow using Flatpak should work.


Meld uses GNOME's GitLab to track bugs, and user questions and development discussions happen on the Meld mailing list. The development team is small, and new contributors are always welcome!
