NAME

diffuse - graphical tool for merging and comparing text files

SYNOPSIS

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, 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 to 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.

RESOURCES

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 ~/.diffuse/diffuserc (%HOME%\.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.

help_file

path to the help document

help_url

URL of the on-line help document

icon

Used Colour Resources


The following colour resources are used by Diffuse:
align
colour used to indicate a line picked for manual alignment

char_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

hatch

colour used for indicating alignment gaps

alpha value used when compositing character difference colours

char_selection_alpha

alpha value used when compositing the character selection colour

alpha value used when compositing line difference colours

line_selection_alpha

alpha value used when compositing the line selection colour

modified_alpha

alpha value used when compositing the modified line 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_pattern name initial_state final_state tag pattern [ignorecase]

Adds a pattern to the previously declared syntax style. The 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.

The following files are used by Diffuse:

/etc/diffuserc

system wide initialisations (%INSTALL_DIR%\diffuserc on Microsoft Windows)

/usr/share/diffuse/syntax/*.syntax
