pod-b12n-mgrep

A babashka pod for interacting with shell. Uses the multigrep to function.

Building prerequisites

• Graal VM
• Clojure CLI(faster) or Leiningen(better windows support)

Building

Installing GraalVM:

• Download and extract GraalVM CE. Go to the extracted location and navigate to the directory where you can find bin, lib, jre and other directories.
• Run export GRAALVM_HOME=$PWD.

Clone the repo and from the repo directory:

• Run $GRAALVM_HOME/bin/gu install native-image to get the Graal native compiler.
• Run clojure -A:native-image if using Clojure CLI or lein native-image with leiningen to compile it to a native executable.
• The executable is found in target/ if compiled via Clojure CLI or in target/default+uberjar/ with leiningen.

Usage via REPL

• Fire up a babashka v0.0.92+ REPL with rlwrap bb
• Import pods: (require '[babashka.pods :as pods])
• Load this pod: (pods/load-pod ["pod-b12n-mgrep"]). Assumes pod-b12n-sh is on the PATH.
• Load the ns: (require '[pod.b12n.mgrep :as mgrep])

Usage as script

#!/usr/bin/env bb
(require '[babashka.pods :as pods])

;; Assumes pod-b12n-mgrep is on your PATH like ~/bin/pod-b12n-mgrep
(pods/load-pod ["pod-b12n-mgrep"])

(require '[pod.b12n.mgrep :as grep])

;; mgrep-project - basic grep 
(mgrep/grep "defproject" "project.clj")

;;greplace! - replace a single key in given file
(mgrep/greplace! "{{db-password}}
                 "<yourdb-password!>"
                  "config.properties")

;; greplace-all! - replace multiple keys in a given file 
(mgrep/greplace-all! {:config-file "/path/to/your-config.properties"
                      :config-map {:db-username "<your-db-username>"
                                   :db-password "<your-db-password>"
                                   ;; and more ..
                                   }
                            :pattern "{{%s}}")
