Open shackra opened 3 months ago

I wish for golang support of the code coverage format, it looks like this:

# ...

With go list -m -json we can guess what part is the name of the module and what's the package:

➜  go list -m -json
{
        "Path": "github.com/shackra/keisy-ian",
        "Main": true,
        "Dir": "/home/jorge/code/crypto/robot-trader/keisy-ian",
        "GoMod": "/home/jorge/code/crypto/robot-trader/keisy-ian/go.mod",
        "GoVersion": "1.21.0"
}

Among many other values.

The format is as follows (taken from a tool that converts this format to lcov):

// Format being parsed is:
//
//  name.go:line.column,line.column numberOfStatements count
//
// e.g.
//
//  github.com/jandelgado/golang-ci-template/main.go:6.14,8.2 1 1
