@pedroql pedroql commented Aug 21, 2020


I did a few improvements on the kotlin lexer. Each commit describes what it does but the main changes are:

  • Detect string interpolation and escaping
"My value is $something and 1 + 2 is ${ 1 + 2}"
"I can do new lines\n"
  • Better detect generics

    • now the reified keyword is properly detected. Before it was just considered Text
class Holder <in A, out B, C: TUpper>

fun <T : Comparable<T>> sort(list: List<T>)  // woohoo! nested generics work

inline fun <reified T>  generic(t: T)

And added a few more tests to verify the functionality around my changes.

Update I was on the wrong branch 🤦‍♂️

The build failed but I don't understand why...

From travis logs:

8.29s$ ./bin/golangci-lint run

lexers/k/kotlin.go:33: File is not `gofmt`-ed with `-s` (gofmt)

I have more than triple checked and gofmt -s -w lexers/k/kotlin.go doesn't change anything. I looked at that line and don't see anything suspicious. I introduced intentional errors (trailing white spaces) and those were removed by gofmt.

$ go version
go version go1.14.7 darwin/amd64

Can someone help?
