Hi,
is a treesitter mode for perl available (somewhere)? Or is one about
to be created?
I'd venture to write one, but looking at [1] tells me that I don't
have a clue how to even begin such an endeavor.

I don't think so.

If you are interested in learning how, you could take a look at this
article, which walks you through creating a simple html-ts-mode:
https://www.masteringemacs.org/article/lets-write-a-treesitter-major-mode
Many of the things written there will carry over to writing a
perl-ts-mode.
The only other thing you need to get started with is a grammar:
https://github.com/tree-sitter-perl/tree-sitter-perl
There is also some info in the Emacs manual under the title
"(elisp)Parsing Program Source"

This is the perl tree-sitter grammar for which I build Windows
binaries (DLLs). I believe there are others however, although I
haven't looked into treesitter enough to be able to understand the
whys and wherefores technically, I can say that the (just barely) most
significant contributor to this grammar project (Paul) is also a
member of the three-person Perl Steering Council which oversees Perl
development.

Are you saying it's not working? And what's the point of having this
when there's no mode to use it with?

It's advertising some package the author's working on too much, and
perl is probably way more complex than html.

Maybe, maybe not.

I thought treesitter would do the parsing. And how do I know if I
have a working treesitter module for perl when I don't even have a
mode to use it with?

If the compiled grammar is available, you can go into any buffer
(regardless if you have a mode or not) and run M-x
treesit-explore-mode. It will prompt you for the name of language and
will open a new buffer with the abstract syntax tree for the buffer
(the result of the parsing).
Last time I tried to dabble into Treesitter, I found go-ts-mode
very helpful. It is a non-trivial yet not too complex example of a tree
sitter mode.

It's a good article to get your feet wet with tree-sitter. Take it or
leave it, but there isn't much content out there to learn from other
than reading tree-sitter modes that already exist, or reading the Emacs
manual. The concepts for syntax highlighting and indentation with
tree-sitter will carry over from html to perl easy enough once you get
comfortable with writing tree-sitter queries.

That section in the manual explains how to use tree-sitter. It does do
the parsing. The name of that part of the manual is very clear imo.

Harald Jörg, the (almost?) maintainer of cperl-mode has started one
on
https://github.com/HaraldJoerg/emacs-perl-ts-mode
but it's very basic so far (as he notes himself!) and does syntax
highlighting only, as far as I can see. Harald also comments on
the treesitter approach for Perl at the end of this post, btw:
https://yhetil.org/emacs-bugs/878r8wa67e.fsf@oook.m.uunet.de/
Plus, as others on this thread have already mentioned, there is no
fully operable treesitter grammar for Perl yet. The one on
https://github.com/tree-sitter-perl/tree-sitter-perl
seems to be the best bet so far.
