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 diffuse-0.4.8.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

Diffuse is a graphical tool for merging and comparing text files.  Diffuse is
able to compare an arbitrary number of files side-by-side and gives users the
ability to manually adjust line matching and directly edit files.  Diffuse can
also retrieve revisions of files from Bazaar, CVS, Darcs, Git, Mercurial,
Monotone, RCS, Subversion, and SVK repositories for comparison and merging.

Some key features of Diffuse:
- ability to compare and merge an arbitrary number of files side-by-side (n-way merges)
- line matching can be manually corrected by the user
- ability to directly edit files
- syntax highlighting
- Bazaar, CVS, Darcs, Git, Mercurial, Monotone, RCS, Subversion, and SVK support
- Unicode support
- unlimited undo
- easy keyboard navigation



- Python >= 2.4
- PyGTK >= 2.10


Diffuse is implemented entirely in Python and should run on any platform with
Python and PyGTK.  If you need to manually install PyGTK, please be aware its
dependencies should be installed prior to installing PyGTK.

Diffuse can be run directly from an untared source distribution on any POSIX
system or installed with the instructions described in the next section.

The location of the personal preferences, state, and initialisation files have
changed in the 0.4.1 release.  Old settings may be migrated using the following

  $ mkdir -p ~/.config/diffuse
  $ mv ~/.diffuse/config ~/.config/diffuse/state
  $ mv ~/.diffuse/* ~/.config/diffuse
  $ rmdir ~/.diffuse

The rules for parsing files in ~/.diffuse changed in the 0.3.0 release.
Non-fatal errors may be reported when parsing old files.  These errors can be
fixed by removing the offending lines (or the entire file) from


Installing on POSIX systems:

Run the 'install.py' script to install Diffuse.  The script accepts several
options for customising the installation behaviour.  Use the '--help' option
to obtain a full listing.

Diffuse can be removed by running the 'install.py' script with the '--remove'

Specify the '--destdir=' and '--files-only' options for the 'install.py'
script when using it to build a platform specific package of Diffuse.


Installing on Windows:

The 'windows-installer' directory contains scripts for building an installable
package for Windows that includes all dependencies.

Diffuse can be packaged as a portable application by copying the installation
directory to a pen drive and creating a front end that sets the XDG_CONFIG_HOME
and XDG_DATA_DIR environment variables prior to launching Diffuse.  The
XDG_CONFIG_HOME and XDG_DATA_DIR environment variables indicate where Diffuse
should store persistent settings (eg. the path to a writable directory on the
pen drive).


Help Documentation:

Diffuse's help documentation is written in the DocBook format and can be easily
converted into other formats using XSLT stylesheets.  If the local help
documentation or its browser are unavailable, Diffuse will attempt to display
the on-line help documentation using a web browser.
