unstack.vim

Parse stack traces or quickfix entries and open the result in vim splits!

Go from this:

To this!

Version 0.5.0

No backwards compatability is guaranteed at this time.

Usage

Visually select part/all of a stacktrace and hit <leader>s. If you want to use a different map key, put let g:unstack_mapkey=<F10> (replacing <F10> with the key of your choice.)

You can also copy a stack trace to your system clipboard (from any program) and run :UnstackFromClipboard.

If this results in too many vsplits crowding the screen, consider taking a look at the accordion plugin (shameless plug).

Signs

By default, Unstack uses signs to highlight lines from stack traces in red. Signs are removed when the tab they were created in is closed. Sometimes a sign will appear to stick around after it's been removed until you switch tabs again. If you want to disable this feature add set unstack_showsigns=0 to your .vimrc.

Portrait Layout

If you want the levels of the stack to open in hsplits (top to bottom instead of left to right), add the following to your .vimrc:

let g:unstack_layout = "portrait"

Line Positioning

By default, the line will be centered on the screen. Alternatively, you can tell Unstack to move the line to the top or bottom of the screen by adding let g:unstack_vertical_alignment = "top"' (or"bottom"`) to your vimrc.

This will respect your scrolloff setting. If you wish unstack to have a different amount of padding than your scrolloff, you can use let g:unstack_scrolloff = 5. Combined with changing the alignment to top, this would put the highlighted line 5 lines from the top of the file.

Note that because vim doesn't let the first line of the file go below the top of the window, if the highlighted line is close to the start of the file, a vertical alignment of middle or bottom will not move the line all the way to the middle/bottom of the window.

Supported Languages

Currently the following stack traces are supported:

  • Python
  • Ruby
  • C#
  • Perl
  • Go
  • Node.js
  • Erlang (R15+)

Is there another language you'd like supported? Open an issue with some sample stack traces or read on to learn how to add custom languages (pull requests welcome).

Customizing Languages

Unstack can easily be extended to support additional stack trace formats. Check out :help unstack_extractors and :help unstack_regex_extractors for more information.

Feel free to submit pull requests or open issues for other stack trace languages.
