prettier-plugin-noshift.js

English | 日本語

A Prettier plugin for formatting NoShift.js (.nsjs) files.

Prettier is an opinionated code formatter. This plugin adds support for .nsjs files — the NoShift.js joke language that lets you write JavaScript without pressing the Shift key.

[!Important]
⚠ Breaking Changes (v0.1.0): Syntax changes in NoShift.js v0.15.0 — ^3 is now #, ^6 is now Capitalize, ^\ is now _. New keyword aliases: or, and, @or, @and.

Install

npm install --save-dev prettier prettier-plugin-noshift.js

Usage

Add the plugin to your .prettierrc:

{
  "plugins": ["prettier-plugin-noshift.js"]
}

Then format your .nsjs files:

npx prettier --write "**/*.nsjs"

Tip: If you scaffold a project with nsc create, Prettier and this plugin are automatically installed and configured.

How It Works

The plugin uses a three-stage pipeline:

1. .nsjs → JavaScript — convert NoShift.js syntax to standard JS
2. JavaScript → formatted JavaScript — format with Prettier's built-in babel parser
3. formatted JavaScript → .nsjs — convert back to NoShift.js syntax

All standard Prettier formatting options are forwarded to stage 2, so your existing config (semi, singleQuote, tabWidth, etc.) just works.

Example

Before (src/index.nsjs):

const  x  =  1  ;
function greet^8name^9 ^[
  const msg=^2^6hello, ^2^;name;
console.log^8msg^9 ;
  return  msg ;
^]

After npx prettier --write:

const x ^- 1;
function greet^8name^9 ^[
  const msg ^- ^2^6hello, ^2 ^; name;
  console.log^8msg^9;
  return msg;
^]

Supported Options

All standard Prettier options are supported. Common ones:

| Option | Default | Description | |---|---|---| | semi | true | Add semicolons at the end of statements | | singleQuote | false | Use single quotes instead of double quotes | | tabWidth | 2 | Indentation width | | trailingComma | "all" | Trailing commas | | printWidth | 80 | Max line width | | bracketSpacing | true | Spaces inside object braces | | arrowParens | "always" | Arrow function parentheses | | endOfLine | "lf" | Line ending style |
