  • Emacs 24 or higher
  • cl-lib 0.5 or higher (you don't need to install cl-lib if you use Emacs 24.3 or higher)


You can install anzu.el from MELPA with package.el

M-x package-install anzu

Basic Usage


Enable global anzu mode:

lisp (global-anzu-mode +1)


Enable anzu minor mode:

lisp (anzu-mode +1)


Same as query-replace except displays anzu information in the mode-line.


Same as query-replace-regexp except displays anzu information in the mode-line.

Screencast of anzu-query-replace-regexp

You can replace key bindings for the standard definitions of query-replace and query-replace-regexp with their anzu versions by adding this snippet to your configuration:

lisp (global-set-key [remap query-replace] 'anzu-query-replace) (global-set-key [remap query-replace-regexp] 'anzu-query-replace-regexp)


Works like anzu-query-replace except the from-string is the symbol at the cursor.


Works like anzu-query-replace-at-cursor except the replacement is constrained to the region specified by the variable anzu-replace-at-cursor-thing. See the variable's description in the customization section for additional details.

Be careful not to confuse this variable with the identically named function (see below).


Like anzu-query-replace-at-cursor-thing, but doesn't query for confirmation before making the substitution.

Be careful not to confuse this function with the identically named customization variable. See the discussion in the anzu-query-replace-at-cursor-thing section.

The anzu version of isearch-query-replace.


The anzu version of isearch-query-replace-regexp.



Face of mode-line anzu information


Face of mode-line at no matching case


Face of from-string of replacement


Face of to-string of replacement


Function which constructs mode-line string. anzu.el puts its output to mode-line. It is called at searching, inputting replaced word, replacing. This must be non-nil.

The function takes 2 integer arguments, current position and total match number. You can get current-state from anzu--state('search, 'replace-query, replace).

```lisp (defun my/anzu-update-func (here total) (when anzu--state (let ((status (cl-case anzu--state (search (format "<%d/%d>" here total)) (replace-query (format "(%d Replaces)" total)) (replace (format "<%d/%d>" here total))))) (propertize status 'face 'anzu-mode-line))))

(custom-set-variables '(anzu-mode-line-update-function #'my/anzu-update-func)) ```

anzu-cons-mode-line-p(Default is t)

Set nil if you want to display anzu information at any position in mode-line. anzu.el cons search information head of mode-line as default.

For example, show search information tail of minor-mode-alist

lisp (setq anzu-cons-mode-line-p nil) (setcar (cdr (assq 'isearch-mode minor-mode-alist)) '(:eval (anzu--update-mode-line)))




Mode name in mode-line. Default is Anzu.

anzu-input-idle-delay(Default is 0.05)

Delay second of updating mode-line information when you input from-string


Commands which have regexp input. If the last command is a member of this list, anzu.el treats input as regular expression.

The default value is '(isearch-forward-regexp isearch-backward-regexp).

anzu-use-migemo(Default is nil)

Set to t if you use migemo.

anzu-search-threshold(Default is nil)

Threshold of searched words. If there are searched word more than this value, anzu.el stops to search and display total number like 1000+(as default). If this value is nil, anzu.el counts all words.


anzu-replace-threshold(Default is nil)

Threshold of replacement overlay. If this value is nil,

anzu-minimum-input-length(Default is 1)

Minimum input length to enable anzu. This parameter is useful for migemo users. Searching 1 or 2 characters with migemo is too heavy if buffer is so large. Please set 3 or higher if you frequently edit such file.

anzu-deactivate-region(Default is nil)

Deactivate region at anzu replace command if this value is non-nil. It is hard to see with anzu replace command when region is active.

anzu-replace-at-cursor-thing(Default is 'defun)

Describes the type of thing used by the anzu-*-thing functions. It can be set to any symbol that is a valid argument for the thing-at-point function, including e.g. defun, word, and page. See the documentation for thing-at-point for additional information.

anzu-replace-to-string-separator(Default is "")

Separator of to string.

Sample Configuration

```lisp (require 'anzu) (global-anzu-mode +1)

(set-face-attribute 'anzu-mode-line nil :foreground "yellow" :weight 'bold)

(custom-set-variables '(anzu-mode-lighter "") '(anzu-deactivate-region t) '(anzu-search-threshold 1000) '(anzu-replace-threshold 50) '(anzu-replace-to-string-separator " => "))

(define-key isearch-mode-map [remap isearch-query-replace] #'anzu-isearch-query-replace) (define-key isearch-mode-map [remap isearch-query-replace-regexp] #'anzu-isearch-query-replace-regexp) ```
