Re: [Matlab-emacs-discuss] Tab-completion (auto-complete) in matlab-mode, not in M-shell

[Eric L. <Eri...@ma...>]

Hi Nor,

The MATLAB path is the current directory, or whatever is in your current MATLAB Path.  Only MATLAB knows what that is, though you could rig something up to mimic that all in Emacs.

Since the current working directory is on the path, if you want to pull completions from a MATLAB process, you need to CD matlab to that location, and probably CD back when you are done getting completions.  That hasn’t been implemented.  There is also just pulling completions for use by autocomplete.  Right now getting those completions is only implemented in the TAB keybinding for matlab shell.   Someone would need to refactor the matlab-shell code to make a handy utility.

As far as setting up an ac-sources, I’m not sure what that means.  If you wanted to make a variable full of all the paths on MATLAB’s path by default, that is certainly a straightforward thing to do.   It is easy to ask MATLAB for its current path.   I just don’t know enough about autocomplete to help make that happen.

Hi Eric,

Thanks for your quick reply. I guess what you mean is that there is no "matlab-sources" that can be added to ac-sources so as I can get aoutocomplete suggestions in matlab-mode, right?

I am looking for competitions in matlab-mode. I would like to get the same behavior of M-shell in matlab-mode. When I type "ff" and I hit TAB twice in M-shell I get a competition list suggestion with "fft fft2 etc". However, when I type "ff" and hit TAB while editing an .m file in matlab-mode, I don't get any suggestion. Is there anyway to get competition suggestions in matlab-mode when editing an .m file or this feature is not implemented?

A way around would be to use autocomplete. Is there any matlab-source to be added to ac-sources to get autocompletition or this is what you say nobody has written a backend for this?

Using the right emacs terms is a little bit hard since I am a beginner :)

Thanks a lot!

Nor

Hi Norberto,

There is OK CEDET support for MATLAB on the sourceforge site, but it isn’t very broad.  As such, you should be able to setup autocomplete and CEDET for MATLAB the same as C or some of the other supported languages.  If you also want MATLAB shell based completions, no one has tried to link those two things together.

To use auto-complete with M-shell, someone would need to write an auto-complete backend that just calls to the same routine that TAB in M-shell uses.   I’ve never created a backend for that, but on the MATLAB shell side you can use ` matlab-shell-completion-list’ to get completions from a string, or copy out chunks of ` matlab-shell-tab’ to get the current text from the shell buffer.

Subject: [Matlab-emacs-discuss] Tab-completion (auto-complete) in matlab-mode, not in M-shell

Hi all,

I'm new to the use of matlab+emacs. I've configured my .emacs so as I'm able to get tab competition in M-shell. However, I'd like to have auto-complete to work together with cedet semantic to get competition suggestions when editing my .m files in matlab-mode (not in M-shell mode).

How do I tell autocomplete to use Matlab sources? Is this possible?

Also, I would like to keep the default mode of auto-completition in M-shell. That is, a pop-up window and a yellow win help information instead of having a separate mini-buffer when hitting twice tab. Any ideas/suggestions?

Thanks!
