multigrep

A little Clojure library that provides regex-based file grepping and/or text substitution.

Installation

multigrep is available as a Maven artifact from Clojars. Plonk the following in your project.clj :dependencies, lein deps and you should be good to go:

[org.clojars.pmonks/multigrep "#.#.#"]

The latest version is:

Trying it Out

Alternatively, you may prefer to kick the library's tyres without creating a project. This is a snap with the awesome lein try plugin:

$ lein try org.clojars.pmonks/multigrep

Or (as of v0.4.0), if you have done a brew install clojure you can simply

$ clj -Sdeps '{:deps {org.clojars.pmonks/spinner {:mvn/version "#.#.#"}}}'  # Where #.#.# is replaced with an actual version number >= 0.4.0

Either way, you will be dropped in a REPL with the library downloaded and ready for use.

Usage

The multigrep functionality is provided by the multigrep.core namespace.

Require it in the REPL:

(require '[multigrep.core :as mg])

Require it in your application:

(ns my-app.core
  (:require [multigrep.core :as mg]))

The library provides two functions - grep (for searching for text within files) and (since v0.3.0) greplace! (for searching and replacing text within files). The API documentation has full details, and the unit tests have comprehensive examples.
