# Vendor files are populated by the build script:
## What the build script does
Using this repo, run `npm install`... the latest versions of:
* `CodeMirror` (https://github.com/codemirror/CodeMirror) is installed.
* `jsonlint` (https://github.com/zaach/jsonlint) is installed.
* `less` (https://github.com/less/less.js) is installed.
* `lz-string-unsafe` (https://github.com/openstyles/lz-string-unsafe) is installed.
* `semver-bundle` (https://github.com/openstyles/semver-bundle) is installed.
* `stylus-lang` (https://github.com/openstyles/stylus-lang-bundle) is installed.
* The necessary build tools are installed; see `devDependencies` in the `package.json`.
## Running the build script
Use `npm run build` to first update the packages in the `node_modules` folder & then update the vendor folder.
The following changes are made:
* `CodeMirror`: Only existing files are updated directly from the `node_modules` folder; see the [CodeMirror readme](codemirror/README.md) for specifics.
* `jsonlint`: The uncompressed `lib/jsonlint.js` is copied directly to `vendor/jsonlint`.
* `less`: The compressed `dist/less.min.js` file is copied directly into `vendor/less`.
* `lz-string-unsafe`: The compressed `lz-string-unsafe.min.js` file is copied directly into `vendor/lz-string-unsafe`.
* `semver-bundle`: The `dist/semver.js` file is copied directly into `vendor/semver`.
* `stylus-lang-bundle`: The `stylus.min.js` file is copied directly into `vendor/stylus-lang-bundle`.
