Diffuse
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
Requirements
Diffuse is implemented entirely in Python and should run on any platform with Python and PyGObject.
- Python >= 3.4
- PyGObject >= 3.18
Users
Installing using Flatpak
This is the easiest way to install Diffuse:
flatpak install io.github.mightycreak.Diffuse
Developers
Setup
Run Diffuse from source
To run Diffuse from the source code, type this:
python main.py
To debug with VS Code, open the directory in VS Code, place your breakpoints and hit F5.
Build Diffuse
To build Diffuse, type this:
python setup.py build
To run from the build, type this:
PYTHONPATH=build/lib ./build/scripts-3.7/diffuse
Install Diffuse locally
Diffuse build system is meson.
To install diffuse locally:
meson setup build
cd build
meson compile
meson install # requires admin privileges
To uninstall diffuse afterwards:
sudo ninja uninstall -C build
sudo rm -v /usr/local/share/locale/*/LC_MESSAGES/diffuse.mo
Meson allows to change the default installation directories, see command-line documentation.
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).
Building and testing the Flatpak package
To install Diffuse locally:
flatpak install runtime/org.gnome.Sdk/$(uname -p)/3.38
flatpak-builder build-flatpak --user --install io.github.mightycreak.Diffuse.yml
To run Diffuse through Flatpak:
flatpak run io.github.mightycreak.Diffuse
To uninstall Diffuse:
flatpak remove io.github.mightycreak.Diffuse
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.
