Dots

Implements the wildcard file matching in Go used by golint, go test etc.

Usage

import "github.com/mgechev/dots"

func main() {
  result, err := dots.Resolve([]string{"./fixtures/..."}, []string{"./fixtures/foo"})
  for _, f := range result {
    fmt.Println(f);
  }
}

If we suppose that we have the following directory structure:

├── README.md
├── fixtures
│   ├── bar
│   │   ├── bar1.go
│   │   └── bar2.go
│   ├── baz
│   │   ├── baz1.go
│   │   ├── baz2.go
│   │   └── baz3.go
│   └── foo
│       ├── foo1.go
│       ├── foo2.go
│       └── foo3.go
└── main.go

The result will be:

fixtures/bar/bar1.go
fixtures/bar/bar2.go
fixtures/baz/baz1.go
fixtures/baz/baz2.go
fixtures/baz/baz3.go

dots supports wildcard in both - the first and the last argument of Resolve, which means that you can ignore files based on a wildcard:

dots.Resolve([]string{"github.com/mgechev/dots"}, []string{"./..."}) // empty list
dots.Resolve([]string{"./fixtures/bar/..."}, []string{"./fixture/foo/...", "./fixtures/baz/..."}) // bar1.go, bar2.go

Preserve package structure

dots allow you to receive a slice of slices where each nested slice represents an individual package:

dots.ResolvePackages([]string{"github.com/mgechev/dots/..."}, []string{})

So we will get the result:

[
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar1.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar2.go"
  ],
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz1.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz2.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz3.go"
  ],
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo1.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo2.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo3.go"
  ],
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz1.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz2.go"
  ],
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo1.go",
    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo2.go"
  ],
  [
    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/bar/bar1.go"
  ]
]

This method is especially useful, when you want to perform type checking over given package from the result.
