`og`: Language and tool enhancements for Go

go get github.com/lunixbochs/og

You can update og to the latest version with og update.

og is a go frontend with additional features, such as a code preprocessor.

Use it as you would the existing go command, like go build or go run.

It also provides the following extra commands:

og help
...
    gen         generate preprocessed source tree
    parse       preprocess one source file
    update      update og command
...

Preprocessor
- Easily perform AST transformations on Go projects as they are built
- Safe: will never modify or overwrite your existing files
- Fast: adds almost no time to your project build

Language Extensions

try(): reduces the if err != nil {} pattern to a single line.

  // before
  tmp, err := call()
  if err != nil {
      return nil, err
  }
  // after
  tmp := try(call())
