shirotakeda / gams-mode Goto Github PK

Hi,

I would like for gams-mode to have a standard emacs auto-completion. I am aware of your gams-ac package, but the auto-complete package is de facto no longer maintained and company-mode is the new standard.

I have started something that seems to work:

• I have imported the full list of GAMS commands (the people from GAMS gave me the location).
• Enabled a standard completion-at-point using this list.
• And for those who wants to use company, I have defined the proper backends. But this is optional, it can works with other completion frameworks since it relies on the emacs standard completion functions.

I barely know elisp, so I did it with a big help from ChatGPT.

Are you interested by a PR?

Hi,

The face inside slashes is the same as the face of the statement. See below

My (limited) understanding of the code is that this should be different, but it does not seem to work. The result is the same if I switch to another theme.

Depending on the statement, it can be quite confusing. See for example:

Hi,

I have started implementing a polymode (https://polymode.github.io) for your gams-mode to handle the Python code embedded in GAMS ($onembedded Python:).

For now, this just lives in my init.el. Are you interested in a PR?

Best,
Christophe

Hi,

I have put in my auto-completion branch which is in the last PR a file to test font-locking: https://github.com/christophe-gouel/gams-mode/blob/auto-completion/test_fontlocking.gms.

I have identified in it two small issues:

• GAMS dollar commands are not colorized if written without dollar on the same line of another dollar command.
• Labels are colorized differently if written with or without quotes. With quotes, the font used is the one used for set elements.

I am sorry but my elisp skills are not good enough to help fix these issues.

These are small issues (the first one is not even dealt with in GAMS Studio), but there may be an easy fix. If not, don't bother.

Hi,

Would it be possible to replace comment-region in what follows by comment-or-uncomment-region? This would allow the same key binding to comment and uncomment.

;; `gams-comment-region' is aliased as `comment-region'.
(if (fboundp 'comment-region)
    (fset 'gams-comment-region 'comment-region)
  (fset 'gams-buffer-substring 'buffer-substring))

Could you consider making gams-mode a mode derived from prog-mode? See https://www.emacswiki.org/emacs/ProgMode#:~:text='prog%2Dmode'%20is%20a,'prog%2Dmode'%20). for details. This would help automatically enable features that are enabled for all programming modes (for example in my case, rainbow delimiters and smart parenthesis).

If was able to program in elisp, I would propose a pull request, but I cannot do anything beyond tinkering with my init.el file.
