diffuse - graphical tool for merging and comparing text filesSYNOPSIS
- diffuse [-h | -? | --help | -v | --version]
- diffuse [--no-rcfile | --rcfile file] [[option...] | [file...]...]
DESCRIPTION
- 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.

FILE COMPARISON
Use the File -> New 2-Way File Merge and File -> New 3-Way File Merge menu items to create additional tabs for comparing text files. File names and revisions can be specified either in the command line arguments used to invoke Diffuse or in fields on the Open File dialogue.
Diffuse displays files side-by-side inserting gaps to align similar lines of text. Differences are highlighted with a different background colour.
Comparison Summary
A summary of the compared files is located in the far right margin. The summary illustrates where gaps have been inserted to align matching lines of text and highlights differences using colour. Manual edits are also highlighted in green. A blue cursor identifies the region currently being viewed. The viewed region can be changed by clicking anywhere on the summary.
Selecting
Lines of text can be selected using the mouse pointer or keyboard. Select lines of text with the mouse pointer by clicking on a line. Click and drag to select multiple lines. Holding down the shift key when clicking will extend the current selection. Select lines using the keyboard by pressing the page up/down or arrow keys. Extend the current selection by holding down the shift key and pressing the page up/down or arrow keys. Move the selection to an adjacent file using the left and right arrow keys.
Matching Lines
The mouse pointer or keyboard can be used to manually align lines of text with adjacent files. To aligning lines of text using the mouse pointer, select a line of text with the left mouse button, right click on a line of text from an adjacent file, and choose Align with Selection. To align lines of text using the keyboard, move the selection with the cursor keys, press the space bar to pick the current line of text, move the selection with the cursor keys to a line of text in an adjacent file, and press the space bar to pick the target line of text. Pressing the escape key will cancel the operation.
Use the Isolate menu item to prevent the selected lines from being matched with any lines from the adjacent files.
Editing
Press the enter key or double-click on a text area to enter text editing mode. The cursor will change to indicate text editing mode and the status bar at the bottom of the window will display the cursor's column position.
In text editing mode, text can be selected with the mouse pointer by click and dragging. The current selection can be extended by holding down the shift key and moving the cursor by clicking with the mouse pointer or pressing any of the arrow, home, end or page up/down keys. Individual words can be selected by double-clicking on them with the mouse pointer. Whole lines can be selected by triple-clicking on them with the mouse pointer.
Modify text by typing on the keyword. Modified lines will be highlighted in green. Use the Undo and Redo menu items to undo and redo the previously preformed operations.
Press the escape key or click on another file's text area using the left mouse button to leave editing mode.
Merging
Use the difference buttons or menu items to navigate between blocks of differences within a file. When navigating, Diffuse will move the selection to the next continuous set of lines with differences or edits.
Use the merge buttons or menu items to copy blocks of text into the selected range of lines. The Undo and Redo menu items can be used to undo and redo the previously preformed operations. All changes to a set of lines can be reverted using the Clear Edits menu item regardless of the order the edits were performed.
VERSION CONTROL
Diffuse can retrieve file revisions from several version control systems via their command line interface. The Microsoft Windows build of Diffuse is able to use both the Cygwin and native versions of the supported version control systems. When using Diffuse with Cygwin, ensure Diffuse's Cygwin preferences correctly describe your system. If the Update paths for Cygwin preference exists for a version control system, it must be enabled to use the Cygwin version.
Version control systems are sensitive to the system path and other environment variable settings. The Launch from a Bash login shell preference may be used to easily set the environment for Cygwin version control systems.
Viewing Uncommitted Modifications
The -m option will cause Diffuse to open comparison tabs for each file the version control system indicates has uncommitted modifications. This is convenient for reviewing all changes before committing or resolving a merge conflict. If no paths are specified the current working directory will be used. For example, view all of your uncommitted modifications with this command line:
-
$ diffuse -m
The default revision of a file will be used for comparison if only one file is specified. For example, this will display a 2-way merge between the default revision of foo.C and the local foo.C file:
-
$ diffuse foo.C
Specifying Revisions
The -r option may also be used to explicitly specify a particular file revision. Any revision specifier understood by the version control system may be used. The local file will be used for comparison if only one file revision is specified. For example, this will display a 2-way merge between revision 123 of foo.C and the local foo.C file:
-
$ diffuse -r 123 foo.C
Multiple file revisions can be compared by specifying multiple -r options. For example, this will display a 2-way merge between revision 123 of foo.C and revision 321 of foo.C:
-
$ diffuse -r 123 -r 321 foo.C
Local files can be mixed with files from the version control system. For example, this will display a 3-way merge between revision MERGE_HEAD of foo.C, the local foo.C file, and revision HEAD of foo.C:
-
$ diffuse -r MERGE_HEAD foo.C foo.C -r HEAD foo.C
For the -c option may be used to easily specify a pair of numerically sequential revisions. For example, this will display a 2-way merge between revision 1.2.2 of foo.C and revision 1.2.3 of foo.C:
-
$ diffuse -c 1.2.3 foo.C
Diffuse does not limit the number of panes that can be used for comparing files. The inputs to a Git octopus merge could be viewed with a command line like this:
-
$ diffuse -r HEAD^1 -r HEAD^2 -r HEAD^3 -r HEAD^4 -r HEAD^5 foo.C
RESOURCES
Resources can be used to customise several aspects of Diffuse's appearance and behaviour such as changing the colours used in the user interface, customising the keyboard shortcuts, adding or replacing syntax highlighting rules, or changing the mapping from file extensions to syntax highlighting rules.
When Diffuse is started, it will read commands from the system wide initialisation file /etc/diffuserc (%INSTALL_DIR%\diffuserc on Microsoft Windows) and then the personal initialisation file ~/.config/diffuse/diffuserc (%HOME%\.config\diffuse\diffuserc on Microsoft Windows). This behaviour can be changed with the --no-rcfile and --rcfile configuration options. A Bourne shell-like lexical analyser is used to parse initialisation commands. Comments and special characters can be embedded using the same style of escaping used in Bourne shell scripts.
General
import file
- Processes initialisation commands from file. Initialisation files will only be processed once.
Key Bindings
keybinding context action key_combination
- Binds a key combination to action when used in context. Specify Shift and Control modifiers by prepending Shift+ and Ctrl+ to key_combination respectively. Keys normally modified by the Shift key should be specified using their modified value if key_combination involves the Shift key. For example, Ctrl+g and Shift+Ctrl+G. Remove bindings for key_combination by specifying None for the action.

Strings
string name value
- Declares a string resource called name with value value.
Used String Resources
The following string resources are used by Diffuse:
character_classes-
- describes mapping used to identify characters of a similar class for selection when double-clicking
This resource is a series of range:value pairs. The range is either a single number or low-high corresponding to the code for the character or characters to be set. Neighbouring characters that map to the same value will be selected as a group when double-clicking on a word.
difference_colours
- a list of colour resources used to indicate differences
- describes mapping used to identify characters of a similar class for selection when double-clicking
Colours
[ colour | color ] name red green blue
- Declares a colour resource called name. Individual colour components should be expressed as a value between 0 and 1.
Used Colour Resources
The following colour resources are used by Diffuse:
alignment-
- colour used to indicate a line picked for manual alignment
character_selection
- colour used to indicate selected characters
cursor
- colour used for the cursor
difference_1
- colour used to identify differences between the first pair of files
difference_2
- colour used to identify differences between the second pair of files
difference_3
- colour used to identify differences between the third pair of files
edited
- colour used to indicate edited lines
hatch
- colour used for indicating alignment gaps
line_number
- colour used for line numbers
line_number_background
- background colour for the line number area
line_selection
- colour used to indicate selected lines
map_background
- background colour for the map area
preedit
- pre-edit text colour
text
- regular text colour
text_background

Floating Point Values
float name value
- Declares a floating point resource called name with value value.
Used Floating Point Resources
The following floating point resources are used by Diffuse:
alignment_opacity-
- opacity used when compositing the manual alignment colour
Defaults: 1
character_difference_opacity
- opacity used when compositing character difference colours
Defaults: 0.4
character_selection_opacity
- opacity used when compositing the character selection colour
Defaults: 0.4
edited_opacity
- opacity used when compositing the edited line colour
Defaults: 0.4
line_difference_alpha
- alpha value used when compositing line difference colours
Defaults: 0.3
line_selection_opacity
- opacity used when compositing the line selection colour
Defaults: 0.4
- opacity used when compositing the manual alignment colour
Syntax Highlighting
syntax name [initial_state default_tag]
- Declares a new syntax style called name. Syntax highlighting uses a simple state machine that transitions between states when certain patterns are matched. The initial state for the state machine will be initial_state. All characters not matched by a pattern will be tagged as default_tag for highlighting. The syntax style called name can be removed by omitting initial_state and default_tag.
syntax_files name [pattern]
- Specifies that files with a name matching pattern should be highlighted using the syntax style called name. Patterns used to match files for use with the syntax style called name can be removed by omitting pattern.
syntax_magic name [pattern [ignorecase]]
- Specifies that files with a first line matching pattern should be highlighted using the syntax style called name. Patterns used to match files for use with the syntax style called name can be removed by omitting pattern.
syntax_pattern name initial_state final_state tag pattern [ignorecase]
- Adds a pattern to the previously declared syntax style. Patterns are tried one at a time in the order they were declared until the first match is found. A pattern will only be used to match characters if the state machine is in the state initial_state. The state machine will transition to final_state if the pattern defined by pattern is matched. Case insensitive pattern matching will be used if ignorecase is specified. All characters matched by the pattern will be tagged as tag for highlighting.
FILES
The following files are used by Diffuse:
/etc/diffuserc
- system wide initialisations (%INSTALL_DIR%\diffuserc on Microsoft Windows)
/usr/share/diffuse/syntax/*.syntax
- syntax files for various languages (%INSTALL_DIR%\syntax\*.syntax on Microsoft Windows)
