I am trying to parse go metafiles in the format of following:

```
require (
    github.com/cheggaaa/pb v1.0.28
    github.com/coreos/go-semver v0.2.0 // indirect
    github.com/coreos/go-systemd v0.0.0-20190321100706-95778dfbb74e // indirect
    github.com/dustin/go-humanize v1.0.0
    github.com/fatih/color v1.7.0
        ...
        )

```

how do I get data between brackets and *without* using a regexp? (otherwise this noobish question would not exist at all). I have tried playing with `split()` but failed so far.
