jjdiff

A TUI that can be used as a diff editor in the jujutsu vcs.

jjdiff will show all changes and allow you to navigate through them and (partially) select them to be included.

jjdiff makes it easy to navigate the diff by having a 2 dimensional cursor that can 'grow' and 'shrink'.

This cursor can operate on 3 levels:

• Change: select an entire change
• Hunk: select a group of edited lines in a file
• Line: select a single edited line in a file

Keybindings

Command	Key	Description
exit	escape, ctrl+c or ctrl+d	Exit the diff editor with status code 1, causing the diff to not be applied.
next_cursor	j, down or tab	Select the next entry.
prev_cursor	k, up or shift+tab	Select the previous entry.
first_cursor	g or home	Select the first entry.
last_cursor	G or end	Select the last entry.
shrink_cursor	l or right	Shrink the cursor. So go from change to hunk and from hunk to line. If the cursor is on an unopened change it will open it first.
grow_cursor	h or left	Grow the cursor. So go from line to hunk and from hunk to change. If the cursor is on an opened change it will close it.
select_cursor	space	Mark everything selected by the cursor to be included. If everything is already marked it will exclude it instead. This will also select the next entry.
select_all	a or ctrl+a	Mark everything in the diff to be included. If everything is already marked it will exclude it instead.
confirm	enter	Confirm the selected changes.
undo	u	Undo the last command. Commands that only affect the UI state like changing the cursor and opening/closing changes are not included in this.
redo	U	Redo the last undone command. Commands that only affect the UI state like changing the cursor and opening/closing changes are not included in this.

Usage

jjdiff is available on pypi. You can use any way you are comfortable installing python applications.

You can then use it by adding the following settings to ~/.config/jj/config.toml:

[ui]
diff-editor = "jjdiff"
diff-instructions = false  # not required but recommended
diff-formatter = ["jjdiff", "--print", "$left", "$right"]  # to also format diffs using jjdiff

Configuration

jjdiff can be configured in ~/.config/jjdiff/config.toml with the following configuration options.

diff.deprioritize

This contains a list of gitignore style globs that can be used to deprioritize certain files in diffs. Deprioritizing has the following effects:

• Deprioritized files are always at the end of the diff.
• In jjdiff --print the changes in deprioritized files are not shown.

format.tab_width

Controls as how many spaces a tab is formatted in the diff. Default is 4.

keybindings

A dictionary mapping command names to lists of keys that should trigger the command. The default value for each command matches the keybindings table shown earlier in this document.
