A daisyUI source file is required

Error message

A daisyUI source file is required

What it means

build-daisyui.js expects exactly one CLI argument: the path to a daisyUI source CSS file. It reads process.argv[2] and throws immediately when that value is falsy. The script then maps the file to one of four source groups, so without an argument it cannot proceed.

Solutions

1. Pass the source CSS file path as the first argument.
2. If calling from a script, ensure the file path is forwarded as process.argv[2].
3. Run with no args only if you meant a different entry point.

Example fix

// before
bun packages/playground/build-daisyui.js
// after
bun packages/playground/build-daisyui.js packages/daisyui/src/components/button.css

const inputFile = process.argv[2]
if (!inputFile) {
  console.error('Usage: build-daisyui.js <packages/daisyui/src/.../file.css>')
  process.exit(2)
}

const isNonEmptyString = (v) => typeof v === 'string' && v.length > 0

When it happens

Trigger: Running `bun packages/playground/build-daisyui.js` (or `node ...`) with no positional argument, or with argv stripped by a wrapper.

Common situations: A new contributor runs the build script directly without reading its usage; a npm/script entry forgets to forward the file path; CI invokes the script in a step that passes no argument.
