diffuse - graphical tool for merging and comparing text files
diffuse [-h | -? | --help | -v | --version] diffuse [--no-rcfile | --rcfile file] [[option...] | [file...]...]
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.
Help Options If a help option is specified, it must be the only argument specified on the command line. Diffuse will immediately quit after displaying the help information. -h, -?, --help Display usage information. -v, --version Display version number and copyright information. Configuration Options If a configuration option is specified, it must be the first argument specified on the command line. --no-rcfile Do not read any initialisation files. --rcfile file Only read initialisation commands from file file. General Options -c, --commit rev Open separate file comparison tabs for all files affected by commit rev from the remaining paths specified in the command line arguments. -D, --close-if-same Close all tabs with no differences. -e, --encoding codec Use codec to read and write files. -L, --label label Display label instead of the file name. -m, --modified Open separate file comparison tabs for all modified files from the remaining paths specified in the command line arguments. -r, --revision rev Include revision rev of the next file named in the command line arguments in a file comparison tab. -s, --separate Open all remaining files specified in the command line arguments in separate file comparison tabs. -t, --tab Start a new tab for any remaining files named in the command line arguments. --line line Start with line line selected. --null-file Create a blank file comparison pane. Display Options Display options specified in the command line arguments will override saved preference values. -b, --ignore-space-change Ignore changes to the amount of white space. -B, --ignore-blank-lines Ignore changes whose lines are all blank. -E, --ignore-end-of-line Ignore end of line differences. -i, --ignore-case Ignore case differences in file contents. -w, --ignore-all-space Ignore all white space.
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.
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 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 are valid for action: open_file File → Open File... menu item Default: Ctrl+o open_file_in_new_tab File → Open File In New Tab... menu item Default: Ctrl+t open_modified_files File → Open Modified Files... menu item Default: Shift+Ctrl+O open_commit File → Open Commit... menu item Default: Shift+Ctrl+T reload_file File → Reload File menu item Default: Shift+Ctrl+R save_file File → Save File menu item Default: Ctrl+s save_file_as File → Save File As... menu item Default: Shift+Ctrl+A save_all File → Save All menu item Default: Shift+Ctrl+S new_2_way_file_merge File → New 2-Way File Merge menu item Default: Ctrl+2 new_3_way_file_merge File → New 3-Way File Merge menu item Default: Ctrl+3 new_n_way_file_merge File → New N-Way File Merge menu item Default: Ctrl+4 close_tab File → Close Tab menu item Default: Ctrl+w undo_close_tab File → Undo Close Tab menu item Default: Shift+Ctrl+w quit File → Quit menu item Default: Ctrl+q undo Edit → Undo menu item Default: Ctrl+z redo Edit → Redo menu item Default: Shift+Ctrl+Z cut Edit → Cut menu item Default: Ctrl+x copy Edit → Copy menu item Default: Ctrl+c paste Edit → Paste menu item Default: Ctrl+v select_all Edit → Select All menu item Default: Ctrl+a clear_edits Edit → Clear Edits menu item Default: Ctrl+r dismiss_all_edits Edit → Dismiss All Edits menu item Default: Ctrl+d find Edit → Find... menu item Default: Ctrl+f find_next Edit → Find Next menu item Default: Ctrl+g find_previous Edit → Find Previous menu item Default: Shift+Ctrl+G go_to_line Edit → Go To Line... menu item Default: Shift+Ctrl+L preferences Edit → Preferences menu item Default: None no_syntax_highlighting View → Syntax Highlighting → None menu item Default: None syntax_highlighting_syntax View → Syntax Highlighting → syntax menu item Default: None realign_all View → Realign All menu item Default: Ctrl+l isolate View → Isolate menu item Default: Ctrl+i first_difference View → First Difference menu item Default: Shift+Ctrl+Up previous_difference View → Previous Difference menu item Default: Ctrl+Up next_difference View → Next Difference menu item Default: Ctrl+Down last_difference View → Last Difference menu item Default: Shift+Ctrl+Down first_tab View → First Tab menu item Default: Shift+Ctrl+Page_Up previous_tab View → Previous Tab menu item Default: Ctrl+Page_Up next_tab View → Next Tab menu item Default: Ctrl+Page_Down last_tab View → Last Tab menu item Default: Shift+Ctrl+Page_Down shift_pane_right View → Shift Pane Right menu item Default: Shift+Ctrl+parenleft shift_pane_left View → Shift Pane Left menu item Default: Shift+Ctrl+parenright convert_to_upper_case Format → Convert To Upper Case menu item Default: Ctrl+u convert_to_lower_case Format → Convert To Lower Case menu item Default: Shift+Ctrl+U sort_lines_in_ascending_order Format → Sort Lines In Ascending Order menu item Default: Ctrl+y sort_lines_in_descending_order Format → Sort Lines In Descending Order menu item Default: Shift+Ctrl+Y remove_trailing_white_space Format → Remove Trailing White Space menu item Default: Ctrl+k convert_tabs_to_spaces Format → Convert Tabs To Spaces menu item Default: Ctrl+b convert_leading_spaces_to_tabs Format → Convert Leading Spaces To Tabs menu item Default: Shift+Ctrl+B increase_indenting Format → Increase Indenting menu item Default: Shift+Ctrl+greater decrease_indenting Format → Decrease Indenting menu item Default: Shift+Ctrl+less convert_to_dos Format → Convert To DOS Format menu item Default: Shift+Ctrl+E convert_to_mac Format → Convert To Mac Format menu item Default: Shift+Ctrl+C convert_to_unix Format → Convert To Unix Format menu item Default: Ctrl+e copy_selection_right Merge → Copy Selection Right menu item Default: Shift+Ctrl+Right copy_selection_left Merge → Copy Selection Left menu item Default: Shift+Ctrl+Left copy_left_into_selection Merge → Copy Left Into Selection menu item Default: Ctrl+Right copy_right_into_selection Merge → Copy Right Into Selection menu item Default: Ctrl+Left merge_from_left_then_right Merge → Merge From Left Then Right menu item Default: Ctrl+m merge_from_right_then_left Merge → Merge From Right Then Left menu item Default: Shift+Ctrl+M help_contents Help → Help Contents menu item Default: F1 about Help → About menu item Default: None Line Editing Mode Key Bindings Use line_mode for the context to define key bindings for line editing mode.

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 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.
