Linter

[christophe-gouel]

Hi,

I have started working on a linter for GAMS mode (a feature present in GAMS Studio). I have put it in a separate file in my repo: gams-flymake.el. For now, it is at an early stage. It works well on small files, but it has to be tested in more complex settings.

The idea is simple: parse the lst file for the errors and highlight the GAMS code with the error using flymake, which is now built-in in emacs. When it will be fully functional, there would be no need to go to the LST files to fix errors.

For now, the approach may be too eager: the linter is launched immediately when you open a GAMS file (only for gms files). It could be better to do as in GAMS Studio, only lint the code after a run (or if asked by the user).
