# Golang complier study

Hi all. This golang fork adds `try` keyword to golang compiler so you do not need to write ```if err != nil ``` every time.
``` go
    try file, err := parser.ParseFile(path)
    fmt.Println(file) 
```

## Usage:

1. Clone this repo.
2. Build compiler with all.bash
3. Compile code with new compiler:

```
~/code/go/bin/go build
```

``` go
func testFn(err error) (int, error) {
    return 99, err
}

func sampleFn() (v int, err error) { // Remember to use named return params for "try" to work properly
    try v, err := testFn(errors.New("test error"))
    panic("not this time")
}
```

Compiler will expand `try` to

``` go
    v, err := testFn(errors.New("test error"))
    if err != nil {
        return
    }
```

## gopls

If you like to add support to gopls just compile gotools fork and move to bin dir.

```
git clone git@github.com:study-gocompiler/gotools.git
cd gotools/gopls
~/code/go/bin/go build
mv gopls TO bin
```
