jjWhen an alias should be unavailable, set `aliases.<name>.enabled` to `false` in a configuration layer. This can disable built-in aliases or aliases defined in earlier layers, including repository configuration.
[aliases]
<name>.enabled = falseWhen editing or deleting a file in a revision, use `jj file edit` or `jj file delete` with the target path; both default to revision `@`, and descendants are rebased after the commit is rewritten.
jj file edit --revision <REVSET> <FILE>When `jj git push` should target a different default revision set, configure `revsets.git-push` with the desired revset. By default, jj pushes tracking bookmarks and tags pointing to revisions in `remote_bookmarks(remote=exact:remote)..@`.
[revsets]
git-push = 'remote_bookmarks(remote=exact:remote)..@'When repository changes need to reach multiple configured Git remotes, run `jj git push` with repeatable `--remote` patterns or set `git.push` to a string pattern or array of patterns.
jj git push --remote '<pattern-1>' --remote '<pattern-2>'When configuring jj’s editor to open a relevant file at a specified line, set `ui.editor` with `$line` for the 1-based line number and `$path` for the file path.
[ui]
editor = ["emacs", "+$line", "$path"]When adding a workspace in a Git-backed repository, use `jj workspace add --colocate <destination>` to create a corresponding Git worktree or `--no-colocate` to prevent one; without either flag, creation depends on whether the current workspace is colocated and `git.colocate` is true.
jj workspace add --colocate <destination>When divergence should be reconciled automatically, run `jj converge`; it uses `revsets.converge` by default and creates a replacement revision using heuristics. If prompts must be avoided, add `--no-interactive`; it warns and exits without changes if it cannot resolve automatically.
jj convergeWhen absorbing only some changes from a source revision, run `jj absorb -i` and select the changes to consider. Selected changes are assigned to eligible ancestors; changes that cannot be assigned unambiguously remain in the source.
jj absorb -iWhen reviewing diff statistics in a narrow layout, set `diff.stat.max-bar-width` to cap the `++--` bar while using `--stat`. For template output, `diff.stat()` accepts an optional `max_bar_width` argument for the same effect.
[diff.stat]
max-bar-width = 10
jj show --statWhen reviewing repository search results, run `jj file search -n --pattern <PATTERN>` to prefix each matching line with its file path and 1-based line number. The pattern is required and defaults to regex syntax when no kind prefix is given.
jj file search -n --pattern '<PATTERN>'
