Quick Start

Playground

Using the playground is the easiest and most convenient way to get started using pomsky. It supports syntax highlighting and shows errors directly in your code.

CLI

The CLI allows you to compile pomsky expressions to regexes in the command line.

Use pre-built binaries

Binaries are available for Windows, Linux and macOS. Download them from the releases page.

Use AUR package

On Arch Linux, you can use the AUR package with

yay -S pomsky-bin

Install from source

This requires that a recent Rust toolchain is installed. Instructions for how to install Rust can be found here.

Install the CLI with

cargo install pomsky-bin

Get help

To find out how to use the CLI, run

pomsky --help

Node module

Pomsky can be used with the @pomsky-lang/compiler-web npm module. Install with

$ npm i -s @pomsky-lang/compiler-web   # yarn add @pomsky-lang/compiler-web

Then import and use it like this:

import init, { compile } from '@pomsky-lang/compiler-web'

init().then(() => {
  const input = `^ ('test' '!'+)? $`
  const { output } = compile(input, 'js')
  console.log(output)
})

It currently works in browsers, but not in Node. If you use vite for bundling, you need to disable optimizations for @pomsky-lang/compiler-web in development mode:

// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig((config) => ({
  optimizeDeps: {
    exclude: config.mode === 'production' ? [] : ['@pomsky-lang/compiler-web'],
  },
}))

The compile function throws an exception if compilation fails.

Rust macro

If you want to write a pomsky expression directly in your Rust source code, the pomsky-macro got you covered. Run this command:

cargo add pomsky-macro

Then you can import and use it with

use pomsky_macro::pomsky;

const MY_REGEX: &str = pomsky!(["great!"] | "great!");
