       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, File → New 3-Way File Merge, and File → New N-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 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.

       Menu Item Key Bindings
           Use menu for the context to define key bindings for menu items. The following values

   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.
