Editorconfig Core Go

A Editorconfig file parser and manipulator for Go.

This package is already working, but still under testing.

Installing

We recommend the use of gopkg.in for this package:

go get -u gopkg.in/editorconfig/editorconfig-core-go.v1

Import by the same path. Tha package name you will use to access it is editorconfig.

import (
    "gopkg.in/editorconfig/editorconfig-core-go.v1"
)

Usage

Parse from file

editorConfig, err := editorconfig.ParseFile("path/to/.editorconfig")
if err != nil {
    log.Fatal(err)
}

Parse from slice of bytes

data := []byte("...")
editorConfig, err := editorconfig.ParseBytes(data)
if err != nil {
    log.Fatal(err)
}

Get definition to a given filename

This method builds a definition to a given filename. This definition is a merge of the properties with selectors that matched the given filename. The lasts sections of the file have preference over the priors.

def := editorConfig.GetDefinitionForFilename("my/file.go")

This definition have the following properties:

type Definition struct {
	Selector string

	Charset                string
	IndentStyle            string
	IndentSize             string
	TabWidth               int
	EndOfLine              string
	TrimTrailingWhitespace bool
	InsertFinalNewline     bool
}

Automatic search for `.editorconfig` files

If you want a definition of a file without having to manually parse the .editorconfig files, you can then use the static version of GetDefinitionForFilename:

def, err := editorconfig.GetDefinitionForFilename("foo/bar/baz/my-file.go")

In the example above, the package will automatically search for .editorconfig files on:

foo/bar/baz/.editorconfig
foo/baz/.editorconfig
foo/.editorconfig

Until it reaches a file with root = true or the root of the filesystem.

Generating a .editorconfig file

You can easily convert a Editorconfig struct to a compatible INI file:

// serialize to slice of bytes
data, err := editorConfig.Serialize()
if err != nil {
    log.Fatal(err)
}

// save directly to file
err := editorConfig.Save("path/to/.editorconfig")
if err != nil {
    log.Fatal(err)
}
