CLI produces no output when invoked via pnpm

[bartveneman]

Description

Running format-css via pnpm produces no output and exits with code 0. The file is silently left empty. The library itself works correctly when imported directly.

Steps to reproduce

Works

node -e "import('@projectwallace/format-css').then(({format}) => console.log(format('a{color:red}')))"

Produces no output, exits 0

echo "a { color: red }" | format-css
format-css styles.css

Root cause

The CLI entry point guards execution with:

if (process.argv[1] === import.meta.filename)

Under pnpm, the bin wrapper (node_modules/.bin/format-css) invokes the script
with an unresolved path:

process.argv[1]      → /project/node_modules/@projectwallace/format-css/dist/cli.mjs
import.meta.filename → /project/node_modules/.pnpm/@projectwallace+format-css@3.1.2/node_modules/@projectwallace/format-css/dist/cli.mjs

These never match, so run() is never called.

Fix

Normalize process.argv[1] before comparing:

import { realpathSync } from 'node:fs'

if (realpathSync(process.argv[1]) === import.meta.filename)
