# less-go 

## THIS PROJECT IS NO LONGER MAINTAINED, feel free to fork and use as boilerplate for further usages

[![Build Status](https://secure.travis-ci.org/kib357/less-go.png?branch=master)](http://travis-ci.org/kib357/less-go)

[Less](http://lesscss.org/) compiler for [Golang](https://golang.org/)

Builds CSS using original [Less compiler](https://github.com/less/less.js) and [Duktape](http://duktape.org/) embeddable Javascript engine

## Status

This project is a work-in-progress, we accept pull requests.

## Installation

```

    go get github.com/kib357/less-go

```

## Command Line usage

```

    cd $GOPATH/src/github.com/kib357/less-go/lessc

    go get

    go build

    ./lessc --input="inputFile" --output="outputFile"

    ./lessc -i inputFile -o outputFile

```

Examples:

```

    ./lessc --input="./styles.less" --output="./styles.css"

    ./lessc -i styles.less -o styles.css

```

More about usage you can see in cli help:

```

    ./lessc -h

```

## Programmatic usage

```go

    import "github.com/kib357/less-go"

    func main() {

        err := less.RenderFile("./styles.less", "./styles.css", map[string]interface{}{"compress": true})

    }

```

### Function reference

#### RenderFile(input, output string, mods ...map[string]interface{}) error

Renders Less and generates output CSS.

#### SetReader(customReader Reader)

```go

    type Reader interface {

	    ReadFile(string) ([]byte, error)

    }

```

Sets a custom reader for .less files. You can use it to replace standard input from file system to another. Example:

```go

    type LessReader struct{}

    var lessFiles = map[string][]byte{"styles": []byte{".class { width: (1 + 1) }"}}

    func (LessReader) ReadFile(path string) ([]byte, error) {

	    lessFile, ok := lessFiles[path]

        if !ok {

            return "", errors.New("path not found")

        }

        return lessFile, nil

    }

    func main() {

        less.SetReader(LessReader)

        ...

    }

```

#### SetWriter(customWriter Writer)

```go

    type Writer interface {

	    WriteFile(string, []byte, os.FileMode) error

    }

```

Analogue of custom reader, but for output CSS.

## Current limitations

Because of using C Javascript engine, cross compilation not supported. Not tested on Windows.

CLI interface doesnt support options
