Grape is a syntax-aware grep-like utility for Clojure code. It allows you to search for code patterns using Clojure data structures.


$ grape [options] <pattern> [<file> ...]

For example, to find all usages of map called with three arguments in grape’s own code:

grape --unindent '(map $ $ $)' src


29:(map match?

137:(map #(when (= %1 %2) %1) prefix line-prefix)


  • -c, --count: show the total matches count and exit.
  • -F, --no-filenames: by default, grape shows the matching filenames when run on multiple files. This option disables that.
  • -u, --unindent: un-indent matches.
  • --line-numbers first|all|none: control line numbers. The default is first, i.e. only the first line of each match is prefixed by its line number. all shows all line numbers; none remove them.
  • -n, --all-line-numbers: alias for --line-numbers all
  • -N, --no-line-numbers: alias for --line-numbers none
  • --inline: force matches on one line. Note this doesn’t change multi-line strings.

Run grape --help to show all options.


Either get the standalone binary (faster) or a jar from the Releases page.

If you have Homebrew, you can install it like so:

brew install bfontaine/utils/grape

Thanks to @ngrunwald, there’s also an Arch Linux grape-bin package. For example, if you use yay:

yay -S grape-bin


Clojars Project

(require '[grape.core :as g])

(def my-code (slurp "myfile.clj"))

;; Find all occurrences of map called with three arguments
(g/find-codes my-code (g/pattern "(map $ $ $)"))

;; Find all occurrences of (condp = ...)
(g/find-codes my-code (g/pattern "(condp = $&)"))

;; Find all occurrences of `if` with no `else` clause
(g/find-codes my-code (g/pattern "(if $ $)"))
; => ({:match "(if …)", :meta {…}}, …)

Matches are map with a :match key that contains a string with the matching code and a :meta key with line/column metadata which you can use to locate the code in your file.


A pattern is any valid Clojure expression. It can contain some special symbols that are interpreted as wildcards.

Comments, whitespaces, and discard reader macros (#_) are ignored when matching.


  • $: any expression.
  • $&: any number of expressions, including zero. (f $&) matches (f), (f 1), (f 1 2), etc.
  • $string, $list, etc: any expression of the given type.

See the full patterns documentation. See more examples.

Wildcards can be combined: #{$ $&} matches a set with at least one element.
