From Middle English este, from Old English ēst (“will, consent, favour, grace, liberality, munificence, bounty, kindness, love, good pleasure, harmony, liberal gifts, luxuries”)
Est is a mixin library based on Less which helps you write Less code more efficiently.
Est provides over 100 handy mixins which generate style rules only when you call them. Est doesn't provide any styles for specific HTML classe names because such “visual classe names” may contaminate HTML semantics. You can build your own style library based on est to accelerate your development.
est can be included in three ways:
import in your Less code:
or just clone it:
$ git clone https://github.com/ecomfe/est.git
// quick import @import 'est/src/all.less'; // override global variables @support-ie-version: 10; @default-font-size: 14px; // ...your own awesome less code starts here...
include using compile options:
install Less plugin:
$ npm install -g less-plugin-est
use the plugin:
$ lessc styles.less --est
If you are using Less version >=
$ lessc styles.less --est --js
use it programatically in Node.js apps:
Plugin Features & Options
Est Less plugin can take two arguments for now:
Automatically import est code before everything.
trueby default. Only works from Less
Eliminate duplicate named at-rules (Less calls them directives). This enables you to define
@keyframesinside mixins and don't have to worry about duplicate output if you call those mixins for several times.
You can specify arguments like this to turn off unwanted features:
$ lessc style.less --est="autoImport=false&uniqueDirectives=false"
When used as a plugin, est requires Less to be
2.0.0 or above. When included using
@import in a Less file, the minimal Less version is
Less supports auto import by plugins only after version
2.4.0. So if you are using older versions, you have to import est using
@import directive in your Less code.
When used as a plugin, est provides
isruleset function (which est used) which is not supported by Less before

Test cases are under
test/specs. One directory for each module and each module can have one or more spec files.
Run this under est project directory:
