[Texmacs-dev] Attempt to migrate to Guile 2.0 (need help)

[Darcy Shen]

I started the attempt several days ago. Now I have completed the cpp part.

The cpp part:
I mainly rebase thlai's work on cpp to the current code base. Apart from some trivial work, it mainly create a texmacs-glue module for the glue code.

The scheme part:
Move some module-related code to texmacs-core.scm. texmacs-core.scm will import the texmacs-glue module, and each scheme module must import texmacs-core by (use-modules (texmacs-core)), in this way the cpp glue functions are exposed to each module.

Then we need to migrate each scm file's (texmacs-module ...) to (define-module ...) and (use-modules ...) to make them compile.

And then I encountered this problem: https://github.com/KarlHegbloom/texmacs/issues/10 (follow the link, there is a error report)

The problem is that after making tm-define.scm compile I can `tm-define` something in `init-texmacs.scm` and it compiles and works. But in the module `tm-preferences.scm`, it will cause a compile error where I use `tm-define`.

Hi all,

Work was begun but not completed. I want to help complete it but have other obligations right now so can't spend full time on it. I'm also not necessarily the most qualified in terms of knowledge and experience,  but will try. The work that was done is on a branch in my git clone,  on github. It was a long time ago.

I think that we should go straight to Guile 2.2.

To me the stumbling block seems that we need to rewrite some scheme bootstrap code to accomodate the new compile/eval model. TeXmacs introduces a custom module system which Guile 2 does not like much. I’m not fluent enough to fix this. All the rest of the scheme code should not pose big problems. Also on C++ side there should not be many changes needed.

Karl, what is the status of your modifications?

Best

Hi,

I can confirm that a similar discussion is happening in Mageia community. I'm
afraid that this will come for other Linux distributions as well in future.

Is there any progress on a port to a recent Guile or another recent scheme
dialect?

Yours,

Ingolf
