Jump through Go stacktraces as easily as grep-mode.

what it looks like

Usage

  1. Hit a panic (debug.PrintStack() doesn't work perfectly, see "BUGS" below)

  2. Highlight/mark region (you can be sloppy because go-stacktracer is smart, just be sure to capture the entire line).

  3. M-x go-stacktracer-region

  4. Use n and p to move up and down, RET to jump to a file (just like grep-mode).

  5. Find bugs and submit patches! I happily accept all issues/pull requests.

Description

When you hit a stacktrace, mark the portion that you want to jump through and then call `go-stacktracer-region' with M-x. The *go-stacktracer* buffer will look something like this:

main.go:20: main.AFunc()
main.go:15: main.AnotherFunc()
main.go:7: main.main()

Use n and p to go down and up (just like grep-mode, *go-stacktracer* is literally a grep-mode buffer).

go-stacktracer uses a regexp to capture the file path and line number, so you don't need to be super precise with the lines you call `go-stacktracer-region' on (though you should be sure to capture the entire line).

BUGS

debug.PrintStack() prints the function name and file path in the opposite order that panic does. I don't handle that case right now, so the function names are off-by-one in the view for debug.PrintStack traces.
