# Editorconfig Core Go
A [Editorconfig][editorconfig] file parser and manipulator for Go.
## Missing features
- escaping comments in values, probably in [go-ini/ini](https://github.com/go-ini/ini)
- [adjacent nested braces](https://github.com/editorconfig/editorconfig-core-test/pull/44)
## Installing
We recommend the use of Go 1.17+ modules for this package. Lower versions, such as 1.13, should be fine.
Import by the same path. The package name you will use to access it is
`editorconfig`.
```go
import "github.com/editorconfig/editorconfig-core-go/v2"
```
## Usage
### Parse from a file
```go
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)
}
```
### Graceful parsing from a file
```go
fp, err := os.Open("path/to/.editorconfig")
if err != nil {
log.Fatal(err)
}
defer fp.Close()
editorConfig, warning, err := editorconfig.ParseGraceful(fp)
if err != nil {
log.Fatal(err)
}
// Log the warning(s) encountered while reading the editorconfig file
if warning != nil {
log.Print(warning)
}
```
### Parse from slice of bytes
```go
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.
```go
def := editorConfig.GetDefinitionForFilename("my/file.go")
```
This definition have the following properties:
```go
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`:
```go
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:
```go
// 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)
}
```
