Re: New paren matching feature request

I still believe that my idea of indetation as an integral over the sexp is better than the current local-parsing idea of identation.

Maybe you will consider it one day.

I don't necessarily disagree.  `local-parsing' has its advantages as
well (mostly it's more robust in cases where we got the syntax wrong,
e.g. because Emacs doesn't know/understand the detailed syntax, or
because the buffer's text is syntactically incorrect).
This said, it should be possible to get the best of both worlds.

Could you refresh our memories about your idea
and how it works?

You are speaking just about "syntactic highlighting" or about both "syntactic highlighting" and indetation ?

First of all it must be installed in lisp, and afterwards it must be re-written in elisp, by extending parse-p-s.

I will make a presentation about the indentation on some suggestive cases of lisp code, and after you understand the idea, il will be easy to undersyand the code commented as it is.

This week I will work on another patch, and when I finish (maybe at the end of the week), I will make a presentation of the indetation. It is an application of the Leibniz-Newton formula.

It was well written in lisp, but not too much commented.

At the end of the next week or during the second week from now I will send at emacs devel a patch at which I am working now, afterwards I will make a presentation of the idea how the automaton for indentation works. After I wrote the automaton for indentation, I saw that in fact it worked exactly like parse-partial-sexp.

Pffffufff. There passed more that 400 years since Giordano Bruno was killed and still the men says jokes. And only 17 years since the professor Ioan Petru Culianu was murdered...

In the Middle Age was defined the evolution of mankind: science was born (due to a religious bill emmited by the pope Inocentium in 1494). At that epoch, the europeans conquered little by little all the world. When they met the cannibals from Oceania, when they saw them , they asked themselves: "All the peuple have soul? Or the soul is just an illusion created by the european culture?". The scientist gave the answer: all the peuple have soul. But the soul of cannibals is attached by a different system of values. They have cultivated another values. That means that they believe in another things.

For exemple, the cannibals from a tribe of Oceania believed that if one does not eat an european, after the death they will be condemned to hit the mug from the bottom of the ocean.

Every action that a man do depends completely on what he believes.

Have you heard about the journalist that wrote an article in Russia a few months ago, and she was injaled into a hospital of mads, and she is injected every day some vaccins to destroy her nervous system? The nowadays ortodixisme does not any longer the values system of the old bizantine ortodoxisme. The was between Russia and America is a religious war...

Re: New paren matching feature request

[A. Soare]

It's a question of belief to decide whether the code of indetation as local-parsing or as a sum is better; I ask myself what is the process of forming of the belief.

In the last past 20 years at least, in the Museums of Egypt the great finger from the hands of the statues dissapeared and continue so. The experts in religious sectes asked themselves why. They found out the answer: the egyptians believe that the soul get out from the statues and can be dangerous. They believe that it can hurt peuple with his hands.

§

Today during the lunch I made an exeperiment at the restaurant:

I asked somebody whether a hand without the great finger can hurt somebody. He said: "Yes, quite so!". He was right. Then I took a knife and hit the table with its top. (without using the great finger). And I saw that the hand without the great finger can be dangerous.

Why the egyptians believe such a thing?

The hand can be dangerous when it moves.
If the soul is held within, it roils motionless.

Likewise, applying an algorithm to a heuristic need can be dangerous.

Unlike the statues, however, we are lucky to have diff and emacs.
I encourage you to refine the patch and post it again after the release.

If you remember, a few months ago I have written an automaton that in one for-loop over a sexp; it returned a list of the correct indentation for that sexp. It also can return a list of the positions and the deep-level of every sexp. More that that, I have said then that it is identically to the automaton from `parse-partial-sexp`. I have told then that my code can be used to colorize all the paranthesis into a different color depending of the level.

I do not understand why nobody considered my code. Otherwise I could have re-writen it in C and included in parse-partial-sexp, and this one could have returned information about indentation too.

Re: New paren matching feature request

I have a feeling that the right way to do this kind of colorization
is through Font Lock mode, and that the hardest part of the job
is hooking it up to the structure of jit-lock.

I agree and I also think that Alin's right in that the best way to do it
is via parse-partial-sexp (suitably enhanced if/as needed).
Font-lock-mode already uses parse-partial-sexp to do
comment&string highlighting.

So the idea would be to modify the syntactic highlighting code?

Yes, tho rather than "modify" I'd call it "extend" or "beef up".

what I meant is to use different colors for nested parentheses of
Lisp code, indicating the hierarchy or the layers, e.g. the outermost
parentheses displayed in red, while the innermost one is violet.
We can try the solar spectrum for them.
