Editorconfig Core Go
A Editorconfig file parser and manipulator for Go.
Missing features
- escaping comments in values, probably in go-ini/ini
- adjacent nested braces
Installing
We recommend the use of Go 1.13+ modules for this package.
Import by the same path. The package name you will use to access it is editorconfig.
import "github.com/editorconfig/editorconfig-core-go/v2"
Usage
Parse from file
fp, err := os.Open("path/to/.editorconfig")
if err != nil {
log.Fatal(err)
}
defer fp.Close()
editorConfig, err := editorconfig.Parse(fp)
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
Raw map[string]string
}
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/.editorconfigfoo/baz/.editorconfigfoo/.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)
}
