regen

Generate optimized regular expressions based of a set of strings.

Get it as a lib:

me.ebbinghaus/regen {:mvn/version "1.0.7"} Clojars

Or a binary

Usage

As a clj cli tool.

❯ clj -M:regen "romane romanus"                                        
(?:roman(?:e|us))

❯ clj -M:regen "romane romanus romulus rubens ruber rubicon rubicundus"
(?:r(?:om(?:an(?:e|us)|ulus)|ub(?:e(?:ns|r)|ic(?:on|undus))))

❯ clj -M:regen < <(curl -s https://raw.githubusercontent.com/dwyl/english-words/master/words.txt) > my-pattern.txt

As a lib

(require '[me.ebbinghaus.regen :as regen])
; => nil
(regen/generate ["romane" "romanus" "romulus" "rubens" "ruber" "rubicon" "rubicundus"])
; => #"(?:r(?:om(?:an(?:e|us)|ulus)|ub(?:e(?:ns|r)|ic(?:on|undus))))"

Build native binary (needs babashka and GraalVM installed):

$ bb native-image    

Run the project's tests:

$ clojure -T:build test

Run the project's CI pipeline and build a JAR:

$ clojure -T:build ci

Install it locally (requires the ci task be run first):

$ clojure -T:build install
