About
-----

[](#about)

`ws_less` is a TYPO3 LESS compiler for compiling LESS files into CSS files. This extensions uses the `LessPHP` compiler.

The extension comes with a cache function. That means the LESS files will be compiled only if necessary.

You can pass values via TypoScript to the LESS files.

Usage
-----

[](#usage)

To include your LESS file, you can use the `page.includeCSS` TypoScript command as usual.

```
page.includeCSS {
  bootstrap = fileadmin/bootstrap/less/bootstrap.less
  bootstrap.outputdir = fileadmin/bootstrap/css/

  responsive = fileadmin/bootstrap/less/responsive.less
  responsive.outputdir = fileadmin/bootstrap/css/

  rte = fileadmin/bootstrap/less/rte.less
  rte.outputdir = fileadmin/rte/css/
  rte.doNotHash = 1 # Disable file name hashing when using LESS variables via TypoScript
}

```

You can also leave off the `outputdir` parameter. The extension will be writing the CSS files into the `typo3temp/ws_less` directory.

### Variables

[](#variables)

You can set LESS variables in TypoScript in template setup part of your template:

```
plugin.tx_wsless.variables {
  var1 = #000
  var2 = #666
}

```

#### Disable file name hashing

[](#disable-file-name-hashing)

For including the generated CSS files in your `ckeditor` YAML config file it is recommended to use the `doNotHash = 1` parameter. When using LESS variables the generated file will be `fileadmin/rte/css/rte.css` instead of `fileadmin/rte/css/rte_468e20047a2589981edd540b083f26c4.css` so you can easily include it in your RTE YAML config using `"contentsCss: "fileadmin/rte/css/rte.css"`

### Development Notice

[](#development-notice)

For developing it is suggested to force-render the template (switching off the TYPO3 template cache) using `admPanel.override.tsdebug.forceTemplateParsing = 1` in your backend user's UserTS config. The LESS files will be compiled on each page load while being logged in as a backend user so you can see the result of your changes without repeatedly clearing the TYPO3 FE cache.
