-# stack
-
-Package stack implements utilities to capture, manipulate, and format call
-stacks. It provides a simpler API than package runtime.
-
-The implementation takes care of the minutia and special cases of interpreting
-the program counter (pc) values returned by runtime.Callers.
-
-## Versioning
-
-Package stack publishes releases via [semver](http://semver.org/) compatible Git
-tags prefixed with a single 'v'. The master branch always contains the latest
-release. The develop branch contains unreleased commits.
-
-## Formatting
-
-Package stack's types implement fmt.Formatter, which provides a simple and
-flexible way to declaratively configure formatting when used with logging or
-error tracking packages.
-
-```go
-func DoTheThing() {
-    c := stack.Caller(0)
-    log.Print(c)          // "source.go:10"
-    log.Printf("%+v", c)  // "pkg/path/source.go:10"
-    log.Printf("%n", c)   // "DoTheThing"
-
-    s := stack.Trace().TrimRuntime()
-    log.Print(s)          // "[source.go:15 caller.go:42 main.go:14]"
-}
-```
-
-See the docs for all of the supported formatting options.

-// pkgFilePath returns the frame's filepath relative to the compile-time GOPATH,

-//
-// As of Go 1.11 there is no direct way to know the compile time GOPATH or
-// module paths at runtime, but we can piece together the desired information
-// from available information. We note that runtime.Frame.Function contains the
-// function name qualified by the package path, which includes the module path
-// but not the GOPATH. We can extract the package path from that and append the
-// last segments of the file path to arrive at the desired package qualified
-// file path. For example, given:
-//
-//    GOPATH          /home/user
-//    import path     pkg/sub
-//    frame.File      /home/user/src/pkg/sub/file.go
-//    frame.Function  pkg/sub.Type.Method
-//    Desired return  pkg/sub/file.go
-//
-// It appears that we simply need to trim ".Type.Method" from frame.Function and
-// append "/" + path.Base(file).
-//
-// But there are other wrinkles. Although it is idiomatic to do so, the internal
-// name of a package is not required to match the last segment of its import
-// path. In addition, the introduction of modules in Go 1.11 allows working
-// without a GOPATH. So we also must make these work right:
-//
-//    GOPATH          /home/user
-//    import path     pkg/go-sub
-//    package name    sub
-//    frame.File      /home/user/src/pkg/go-sub/file.go
-//    frame.Function  pkg/sub.Type.Method
-//    Desired return  pkg/go-sub/file.go
-//
-//    Module path     pkg/v2
-//    import path     pkg/v2/go-sub
-//    package name    sub
-//    frame.File      /home/user/cloned-pkg/go-sub/file.go
-//    frame.Function  pkg/v2/sub.Type.Method
-//    Desired return  pkg/v2/go-sub/file.go
-//
-// We can handle all of these situations by using the package path extracted
-// from frame.Function up to, but not including, the last segment as the prefix
-// and the last two segments of frame.File as the suffix of the returned path.
-// This preserves the existing behavior when working in a GOPATH without modules
-// and a semantically equivalent behavior when used in module aware project.
