I have not tried to use xiki in any other editor, if this is bug is actually a bug of xiki itself, please let me know and I will repost the issue there.

[lunixbochs]

SublimeXiki has a very minimal approach to integration. When I originally integrated, I didn't see a good way to run commands through Xiki, so I implemented it myself in Sublime (which allowed me to do nice async output). This means commands like ls don't work the same way as inside Xiki. It might be a simple change to pass nested command invocations through Xiki, but I haven't looked at the xiki command specs in forever.

An easy solution to the ls problem is to use the native folder navigation - just skip $ ls and invoke paths directly.

[Zauberfisch]

wait, so are you saying this is a re-implementation of xiki?

[lunixbochs]

No. There's a Xiki command-line interface. It didn't give me a good way to do things like directory trees and executing shell commands, so I wrote that part myself. All of the errors you saw before are output from the Xiki command-line interface. I don't know how the nested command feature works inside Xiki.

[Zauberfisch]

I see,
well, your suggestion using just the path works.
and I am not sure how much I will actually use SublimeXiki, so I not to overly atteched to this,
but it still is a bug that should be fixed ;)

[joenorton]

Ah, I just posted this as an issue on the main Xiki repo.

This directory not working business is pervasive in the menus. It really needs to be fixed.

I can't even run through the example command: docs
without running into the bug

  @open file//Users/joenorton/menu/docs.txt
    undefined local variable or method `dir' for Xiki::DirHandler:Class
