Loop and Configuration

[maranqz]

Hello,

I created linter, and I want to have ability to change list of packages (m.Import) without changing the code.
Could I do it, are there planes to implement?
That help to config and set custom settings.

package write

import (
	"strings"

	"github.com/quasilyte/go-ruleguard/dsl"
	"github.com/quasilyte/go-ruleguard/dsl/types"
)

// https://github.com/quasilyte/go-ruleguard/blob/master/_docs/dsl.md#creating-a-ruleguard-bundle
var Bundle = dsl.Bundle{}

func factory(m dsl.Matcher) {
	m.Import("ddd/testdata/src/write/nested")
	m.Import("ddd/testdata/src/write/nested/nested2")

	m.Match("$x.$field = $_", "$x.$field++").
		//Where(m["x"].Filter(isWrite)).
		//Report(`$x.$field is readonly`)
		Do(report)
}

func report(ctx *dsl.DoContext) {
	typX := ctx.Var("x").Type()

	asPointer := types.AsPointer(typX)
	if asPointer != nil {
		typX = asPointer.Elem()
	}

	if strings.HasPrefix(typX.String(), "ddd/testdata/src/write/nested.") ||
		strings.HasPrefix(typX.String(), "ddd/testdata/src/write/nested/nested2.") {
		field := ctx.Var("field")

		ctx.SetReport(typX.String() + "." + field.Text())
	}

}

Hmm.
The only thing that comes to my mind is binding the values at the command line.
Like running the ruleguard with named values specified to substitute variables in the rules file.
Something akin to the way we can bind Go constants with a linker.

Any other ideas?
