Customizing

Essential Settings

User Option: majutsu-jj-executable: Path to the jj binary (default: "jj").
User Option: majutsu-jj-global-arguments: Global arguments passed to all jj commands (default: ("--no-pager" "--color=always")).
User Option: majutsu-jj-diffstat-columns: Column width used only for jj diff --stat (default: 80). Set to nil to inherit terminal width. Raise it if you want more full path visibility; keep it near 80 if you prefer compact stat bars.
User Option: majutsu-transient-default-action: Key used for primary/default action suffixes in Majutsu transients (default: RET). Set it to another key description, such as ., to move the default action key.
User Option: majutsu-show-process-buffer-hint: Whether to append a process-buffer hint to jj errors. The displayed key is resolved from the active bindings, so Vanilla normally shows $ and Evil normally shows `.
User Option: majutsu-debug: Enable debug logging for jj operations.
User Option: majutsu-show-command-output: Show jj command output in messages.

Confirmation Settings

User Option: majutsu-confirm-critical-actions: If non-nil, prompt for confirmation before critical operations like abandon, undo, redo, rebase.
User Option: majutsu-no-confirm: A list of symbols for actions Majutsu should not confirm, or t to never confirm. Valid symbols: undo, redo, abandon, bookmark-delete, tag-delete, git-remote-remove, rebase, workspace-forget, and workspace-trash.
User Option: majutsu-slow-confirm: A list from the same action set that should use yes-or-no-p instead of y-or-n-p, or t for all of them.

Process Options

User Option: majutsu-process-popup-time: Popup the process buffer if a command takes longer than this many seconds. -1 means never, 0 means immediately.
User Option: majutsu-process-log-max: Maximum number of sections to keep in a process log buffer (default: 32).
User Option: majutsu-process-apply-ansi-colors: When non-nil, convert ANSI escapes in jj output to text properties.
User Option: majutsu-process-timestamp-format: Format string for process log section timestamps.
User Option: majutsu-jj-environment: Extra KEY=VALUE entries prepended to subprocess environments for all jj invocations (local and TRAMP), applied centrally by majutsu-process.

Display Options

User Option: majutsu-log-commit-columns: Flat log row column declarations controlling templates, modules, face policy, and postprocessing. For protocol details, module semantics, and examples, see Inspecting -> Log Buffer.
Template family: majutsu-log-template-<field>: Template forms consumed by log fields. For newline and control-character rules, see Inspecting -> Log Buffer.
User Option: majutsu-log-sections-hook: Hook run to insert sections in the log buffer.
User Option: majutsu-display-buffer-function: Magit-style display strategy (default: majutsu-display-buffer-traditional). Built-in alternatives are majutsu-display-buffer-same-window-except-diff-v1, majutsu-display-buffer-fullframe-log-v1, majutsu-display-buffer-fullframe-log-topleft-v1, majutsu-display-buffer-fullcolumn-most-v1, and display-buffer.
User Option: majutsu-pre-display-buffer-hook: Hook run before displaying a buffer.
User Option: majutsu-post-display-buffer-hook: Normal hook run after displaying a buffer.
User Option: majutsu-bury-buffer-function: Function used by q to bury/quit Majutsu buffers (default: majutsu-mode-quit-window; alternatives include quit-window and majutsu-restore-window-configuration).

Diff Options

User Option: majutsu-diff-refine-hunk: Whether to show word-granularity differences inside hunks. nil disables, t refines the current hunk, and 'all refines all hunks.
User Option: majutsu-diff-fontify-hunk: Whether to apply syntax highlighting to diff hunks. nil disables, t fontifies a hunk when it becomes current, and 'all fontifies all hunks immediately. This is synchronous and can be slow on large diffs.
User Option: majutsu-diff-refine-ignore-whitespace: Whether to ignore whitespace while refining hunks.
User Option: majutsu-diff-paint-whitespace: Whether to highlight whitespace issues inside diff hunks.
User Option: majutsu-diff-highlight-trailing: Whether to mark trailing whitespace in diff hunks.

Buffer Hooks

User Option: majutsu-create-buffer-hook: Normal hook run when a new Majutsu buffer is created.
User Option: majutsu-setup-buffer-hook: Normal hook run after displaying the buffer.
User Option: majutsu-post-create-buffer-hook: Normal hook run after the initial refresh.
User Option: majutsu-refresh-buffer-hook: Normal hook run after refreshing.

Description Options

User Option: majutsu-jjdescription-major-mode: Major mode used for editing JJ description buffers (default: text-mode).
User Option: majutsu-jjdescription-summary-max-length: Column beyond which summary line characters are highlighted (default: 68, same as Magit). Set this option to nil to disable highlighting; zero highlights the entire nonempty summary.
User Option: majutsu-jjdescription-fill-column: Local fill-column used in JJ description buffers (default: 72). A positive integer enables Auto Fill for the body but never folds the summary line; filling is delegated to the selected major mode, so constructs that mode protects (such as Org headings, tables, and blocks) remain intact. Set this option to nil to disable Auto Fill and leave the buffer's current fill-column unchanged.
User Option: majutsu-jjdescription-comment-prefix: Comment prefix used in JJ description buffers (default: "JJ:").
Face: majutsu-jjdescription-change-id-face: Face used for JJ Change ID values.
Minor mode: global-majutsu-jjdescription-mode: Global minor mode to enable JJ description buffer enhancements.

Evil Integration

User Option: majutsu-evil-enable-integration: Set to nil to disable automatic Evil bindings.
User Option: majutsu-evil-initial-state: The Evil state to start in (default: normal).

When Evil integration is enabled, the dispatcher displays and accepts the same Evil-facing top-level keys used in Majutsu buffers, including x, L, _, *, u, C-r, and `. The global Evil v binding remains Visual state; open evolog from the dispatcher with ? v.
