7
8 Package stack implements utilities to capture, manipulate, and format call
9 stacks. It provides a simpler API than package runtime.
10
11 The implementation takes care of the minutia and special cases of interpreting
12 the program counter (pc) values returned by runtime.Callers.
13
14 ## Versioning
15
16 Package stack publishes releases via [semver](http://semver.org/) compatible Git
17 tags prefixed with a single 'v'. The master branch always contains the latest
18 release. The develop branch contains unreleased commits.
19
20 ## Formatting
21
22 Package stack's types implement fmt.Formatter, which provides a simple and
23 flexible way to declaratively configure formatting when used with logging or
24 error tracking packages.

26 ```go
27 func DoTheThing() {
28     c := stack.Caller(0)
29     log.Print(c)          // "source.go:10"
30     log.Printf("%+v", c)  // "pkg/path/source.go:10"
31     log.Printf("%n", c)   // "DoTheThing"
32
33     s := stack.Trace().TrimRuntime()
34     log.Print(s)          // "[source.go:15 caller.go:42 main.go:14]"
35 }
36 ```

38 See the docs for all of the supported formatting options.
