Node.js wrapper for ZPrint Clojure source code formatter

Usage

CLI

Install

npm i -g zprint-clj

Format and write back

zprint-clj -i "./src/**/*.{clj,cljs,cljc,edn}" -o ./

Check formatting without writing (useful for CI)

zprint-clj --check "./src/**/*.{clj,cljs,cljc,edn}"

API

npm i zprint-clj
const printFile = require('zprint-clj');
const outputText = format(inputText, inputFilePath, opts);

Options

  • isHangEnabled true|false — enable hang mode (disabled by default), slows down formatting, but results in better formatted output

Difference between output when Hang mode is on and off

Advanced Configuration

You can configure zprint-clj with a .zprintrc file. The .zprintrc is written in EDN format.

Your .zprintrc file will be resolved if it is found in one of two locations:

  1. The current directory where the zprint-clj process was initialized
  2. The global HOME directory

If none found, we fall back on zprint-clj default settings.

Building

production

clojure scripts/build.clj

debug

clojure scripts/build_debug.clj

Local Development

The following guide outlines how to locally develop zprint-clj. Please make sure you have the clj cli tool installed.

  • Install zprint-clj dependencies

    npm install
    
  • Make your your code changes in the src directory

  • Compile your changes

    clojure scripts/build_debug.clj
    
  • Update js-src/index to look like this

    const zp = require("../out/main-debug").zprint_clj.core;
    

    This tells zprint-clj to use the debug version

  • Create a test Clojure file with some test code you want to see formatted

  • Open the test file in your editor of choice

  • Run zprint-clj against your test file

    js-src/cli.js -i <your-filename-here> -o <your-filename-here>
    

    If you are running in a different directory you will have to update above path to js-src/cli.js. The reason we run this instead of main-debug is because cli, or index, act as the entry points for JS for this library.
