Debian 7 load module problem about emacs-elixir HOT 11 CLOSED

Same function runtime issue. 'pcase is not defined.
If you rewrite rules in other style it should solve runtime problem:

(defun vki-elixir-smie-rules (kind token)
  (case kind
    (:elem
     (cond
      ((equal basic) elixir-smie-indent-basic)))
    (:after
     (cond
      ((equal token "OP") elixir-smie-indent-basic)
      ((equal token "->") elixir-smie-indent-basic)))
    (:before
     (cond
      ((equal token "OP") elixir-smie-indent-basic)
      ))
    ))

For compilation problem I still can't figure whats wrong with coma here: (:list-intro . ,(or "do"))`

It appears pcase was introduced in Emacs 24. The latest official version is 24.3, released in March 2013. I think for now I am going to mark this ticket as closed, and recommend you upgrade to the latest version (if you haven't already, by now).

from emacs-elixir.

So the only robust 'solution' to this is to upgrade to Emacs24? I have other plug-ins that don't play nicely with that version, so presumably I either choose elixir-mode or these other plug-ins?

from emacs-elixir.

Yes, unfortunately.

Alternatively you could contribute a patch that adds support for emacs 23

from emacs-elixir.

Here's the source for pcase, which as far as I can tell is the source of the issue. If you wanted, we can talk about a patch that includes this... or perhaps another approach to write smie-rules functions that is compatible with Emacs 23. (Assuming that's the only issue.)

from emacs-elixir.

In theory, could this pcase macro just be bundled and required as appropriate, i.e. even adding it separately in your loadpath?

Also, is there a surefire fix for the ". in wrong context" error? Could it be consolidated somehow?

Is this a potential summary of where something has to be done to remedy the error on load?

elixir-smie.el:308:    (`(:before . "def") elixir-smie-indent-basic)
elixir-smie.el:313:    (`(:after . "->")
elixir-smie.el:318:    (`(,_ . ,(or `"COMMA")) (smie-rule-separator kind))
elixir-smie.el:319:    (`(:after . "=") elixir-smie-indent-basic)
elixir-smie.el:320:    (`(:after . "end") 0)
elixir-smie.el:321:    (`(:after . ,(or `"do"))
elixir-smie.el:323:    (`(:list-intro . ,(or `"do" `";")) t)))

I am not well versed enough in elisp, elixir or this emacs-plugin to know what to do with this.

from emacs-elixir.

This syntax is called a cons cell:

(x . y)

I am operating under the assumption that the . in wrong context error is an error that cascades down from pcase not existing, or an earlier version of it that had different syntax, or something.

from emacs-elixir.

I am aware of what a cons cell is, but clearly these are not working just like regular cons cells in the context of the errors.

from emacs-elixir.

I'm not sure. I'll try to look into this this weekend on emacs 23

from emacs-elixir.

Actually, if you're interested in running this to ground I'll re-open the ticket. Unfortunately I don't have the bandwidth to add support for another emacs version, not to say it's not objectively worthwhile.

from emacs-elixir.

I wouldn't advise that. I'm sure the time and effort is better spent elsewhere.
