@jakob My changes were included in Guile in december 2024, and they are already in the most recent release.

6750f6cc8 PEG: string-peg: Add HTML5 grammar test.
38ad26497 PEG: string-peg: Better support for escaping.
c86a48a92 PEG: string-peg: Fix [^...] interpretation.
25504ba21 PEG: Add support for `not-in-range` and [^...]
ff11753df PEG: Add full support for PEG + some extensions

@jakob HEY! that's NOT true!
I renewed the string-peg a little bit not that long ago, and @regtur has prepared a great PR with improvements to PEG.
If you are interested on it, please help me review!

There it is, a fresh #GNU Mes #scheme #interpreter work blog post.

This time giving more answers than questions.

Long term work is hard, dudes.

By default it has a commonmark parser which is problematic, because it does not support a few things I use a lot: footnotes.

It doesn't support ids on headers either.

So I could convert the posts to sxml or html with other tool and migrate them like that, or I could add a new parser that actually supports those features.

I don't dislike simplifying my future post style or move to texinfo, which is better supported.

It's pretty flexible. Exactly the kind of flexibility that gives you freedom, and it's small enough for me to understand it.

Hey this Guile Haunt thingie looks pretty cool.

I think I'm going to move some sites to that!

@janneke /me dislikes emacs more each time people pushes him to use it.

@janneke I know, but it's also a huge program that I cannot read entirely on my own. That's a concern that I have.

And also I don't love a few things from it.

I have talked with Prot about it and with some other emacs enthusiasts, and I think my goal of making my own simple text editor is the only way out.

I don't like much from GNU projects is many are emacs dependent, and overlook any other usecase.

@janneke 🙃 is that freedom?

Why is gdb's TUI so bad when you print to stdout?

Everything goes to hell when you do some printing!

Any idea, suggestion, tool, alternative UI or anything you use that can make this more comfortable?

(is it just because you are supposed to use emacs with it?)

@janneke did you try pijul or darcs? those are supposed to work with independent patches way easier!

@janneke @cnx I like the approach but in a way that would destroy the process of reaching the conclusions I reached. In some commits, it's interesting, others are just silly fixes. But yeah, it's a reasonable balance.

About the commits, it's probably me that I'm that kind of "all over the place" programmers that touch too many things at the same time and when I make the commits I sometimes have interleaved things that are then hard to reorder for squashing...

@janneke @cnx From the top of my head, for example a tool like fossil where the commits are immutable, could keep track the fixups and, regardless if they are mixed with other dependent commits in between, could allow for querying a fixup history for one commit and understand it in context...
That could be an interesting way to logically organize the changes, but in the query, and not when the change is introduced.

@janneke @cnx Being more organized would help here, but I don't want the politics of a project or the tool that I use (git in this case) to dictate how should I work.

I prefer to let the fixes come first and adapt the policy and the tool to support that.

(Now I'm not saying we should change the tool in Mes or the policy, I think it is fine. I'm just trying to think about a different paradigm of something that would fit my brain better)

@janneke @civodul @wingo Yes, the module system is one of the things that produces most of this Scheme->C->Scheme dance and also guile having a different behavior when it's AOT compiled vs when it's interpreting makes everything very hard: It forces us to expand+compile+evaluate top-level expressions one by one, with all the problems that has.

@civodul @janneke @wingo One of the most limiting things I found is the context switches between C and Scheme, that sometimes can trigger some `eval` that makes another context switch.

Also, moving a few things (like arithmetic operators) to opcodes makes everything WAAAAY faster, but that disallows making things like (define (+ . x) whatever) if it's not done carefully. Do you have any trick for this?

Now I realized I need to write a version control system from scratch, too, because Git is too complex for my taste.

My computing setup needs something better.

I'm reading a little bit about diffing algorithms and all that. Interesting stuff, probably too hard for me.

@suetanvil yeah, but that means having git, that wouldn't remove any dependency or make the software simpler in any way.

@futurile @suetanvil I don't dislike the ux of git, but I dislike how they continue to add new commands all day and some of the weird decisions they are moving towards.
Also monorepo support, submodules and all that are things I don't need and I think make the whole thing too complicated.

I've been researching darcs and pijul, specially the second. They are truly interesting.

The changes are understood as commutative operations, and everything is built from there.

@cnx @suetanvil @futurile Sure, yeah! I researched fossil in the past. I don't know if I like the no-rebase approach where the changes are immutable, but it's also very interesting. It goes the other way around, right?

Pijul and Darcs are designed for re-ordering and fossil for quite the opposite.
