Can't get Xiki loaded

[Manu]

Hi,

I installed Xiki according to the instructions on the github page but when i try to run emacs it fails with the following message:

Debugger entered--Lisp error: (invalid-read-syntax "#")
  signal(invalid-read-syntax ("#"))
  (condition-case err (eval (setq expr (read result))) (el4r-ruby-error (signal (quote el4r-ruby-error) nil)) (error (setq el4r-error-lisp-expression expr) (signal (car err) (cdr err))))
  (let ((result (el4r-recv)) expr) (while (eq (length result) 0) (el4r-wait-expr) (setq result (el4r-recv))) (condition-case err (eval (setq expr (read result))) (el4r-ruby-error (signal (quote el4r-ruby-error) nil)) (error (setq el4r-error-lisp-expression expr) (signal (car err) (cdr err)))))
  el4r-get()
  (let ((result (el4r-get))) (el4r-leave-call) result)
  el4r-ruby-eval("el4r_boot")
  el4r-boot()
  eval-buffer(#<buffer  *load*> nil "/home/manu/.emacs" nil t)  ; Reading at buffer position 8161
  load-with-code-conversion("/home/manu/.emacs" "/home/manu/.emacs" t t)
  load("~/.emacs" t t)

Since I don't know any lisp, I'd be really happy if someone could help me outh with this.

I don't think I've seen that error before. Try using ruby 1.9.3 if
you're not already doing so.

ruby --version gives me this:
 $  ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
so it seems, I'm already using 1.9.3

[Manu]

The el4r log file says this:
2013-02-13 11:26:22 +0100:Starting, waiting for expression.
and nothing else...

[Manu]

Sorry for spamming, but this time I got a little more output:
2013-02-13 11:28:15 +0100:Starting, waiting for expression.

I got it running :)
The error had nothing to do with Xiki. As it turned out, my bookmark file was corrupted. After reverting it, xiki started without difficulty

[Craig Muth]

Awesome!

Maybe it's worth adding a bullet to the troubleshooting section
suggesting people comment out the lines that enable Xiki, in case
things get into a weird state like that.

> my bookmark file was corrupted.

I believe the bookmark syntax changed between emacs versions (22 and
23 maybe). That might be related.

Btw I'm working on a tutorial to make the initial experience of
learning xiki easier. You'll be able to type "tutorial" and it'll
walk you through doing the basic things. (I'm holding off pushing the
in-progress version due to some refactors that will change the initial
steps).

[Manu]

I'm not sure about that since the error wasn't caused by Xiki. It would've popped up on other apps that try to access the bookmark file, too. Also commenting out wouldn't solve the problem, but just hide it.
