# 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.
