Validating tree-sitter major modes and grammar

Validating tree-sitter major modes and grammar

[Yuan Fu]

Continuing from the tree-sitter maternity thread, I cooked up some script to go over each builtin tree-sitter mode, clone the grammars it uses, and check whether the font-lock queries are compatible with the latest version of the grammar. If everything works fine, the script adds some comment in the source file listing the version that was checked.

For example, I ran the script for c-ts-mode and c++-ts-mode, and this is the comment inserted to c-ts-mode.el:

;;; Tree-sitter language versions
;;
;; c-ts-mode is known to work with the following languages and version:
;; - tree-sitter-c: v0.20.8-61-g3efee11
;;
;; c++-ts-mode is known to work with the following languages and version:
;; - tree-sitter-cpp: v0.20.5-49-gf41b4f6
;;
;; We try our best to make builtin modes work with latest grammar
;; versions, so a more recent grammar version has a good chance to work.
;; Send us a bug report if it doesn't.

The version is taken from “git describe”. If the grammar isn’t versioned, it’ll just be the hash of HEAD. In order for “git describe” to work, I had to do full clones, and some tree-sitter grammar’s repo is very slow to clone. I wonder if there’s anything we can do to speed it up? 

Any thoughts/comments? I pushed the code to master so others can play with it.

BTW, the script revealed that cmake-ts-mode isn’t compatible with the latest grammar. I’ll try fix it later.

It’s for maintainers, I moved the script to admin/treesit-admin.el.

Oh that sounds very good. This could be a good workaround for the sort
of fast and lose nature of tree-sitter.

CC’ing maintainers for builtin modes for comments. Also, Eli, what’s your thoughts on this after the clarification?

Great. Do you think the “verified version” comment will be helpful for packagers?

It helps answer the question, “I am building a new Emacs release.  Do I need to update these Tree-sitter parsers?”.

However, as a parser packager, I also need to answer the question, “This parser has released a new version.  Can I package it now, or do I need to wait for Emacs 30?  Emacs 31?”.  A static comment in the source code of a released version of Emacs will likely be too out-of-date to answer that.

Other ideas:

- Run these checks regularly (from https://emba.gnu.org/, perhaps?) for the most-recent Emacs release, outputting a report or webpage that can be referred to by packagers.

- Include a function in Emacs that packagers can call themselves to check the compatibility of installed parsers.  They could run this check every time they build an updated parser (either manually, as a part of the package build, or as a part of their distribution’s automated CI testing).

This is performed already, see the GitLab jobs build-image-tree-sitter
and test-tree-sitter.

Recent results are for example
<https://emba.gnu.org/emacs/emacs/-/jobs/95076> and
<https://emba.gnu.org/emacs/emacs/-/jobs/95071>.

About running the script semi-regularly and adding recommended version comments to builtin modes. Are there any concerns?

If most people think it’s a good idea, I’ll run the script for all the builtin modes, which will add the comments. And I plan to run it myself from time to time to update the comments. Maintainers for a particular mode can also run it to update the comment themselves. And I’ll add more detailed documentation about how to use the script.

It would be helpful in case something goes wrong as a kind of sanity
check but it won't help much for an indicator when to update since I
don't think that would be blocker for updating.

It is helpful but none the less the goal should be that such errors
should be preventable between grammar versions.

I can add another script that finds the latest “version” that’s compatible with a builtin mode. The comments will be helpful for packaging a new Emacs release. And the new script can help with packaging new grammar versions with Emacs.

Sounds great to me.

Hopefully we manage to convey well that the "last tested version" is not 
necessarily the latest that will work, just the one that we tested.

Right now the comment says this at the end:

Is it possible for EMBA to run a CI which produces a HTML webpage, and host that webpage somewhere? I’m referring to this idea of Peter’s. 

> - Run these checks regularly (from https://emba.gnu.org/, perhaps?) for the most-recent Emacs release, outputting a report or webpage that can be referred to by packagers.

I’m thinking of a table where rows are languages, columns are Emacs releases (29, 30, master), and cells are the latest revision of a language grammar that’s compatible with an Emacs release.

Just a nit, but we could add "too" at the end:

   so a more recent grammar has a good chance to work too.

(I removed the word "version" for easier refilling, but that's 
definitely not neccesary.)

About the paragraph before, just a thought but do we want to use a 
standard phrase like "has been tested":

   ;; c-ts-mode has been tested with the following languages and version:

? Seems a bit more regular for a casual reader, which conveying the same 
meaning. I'm not a native speaker, though.

In general it is possible, using a GitLab feature called Pages (https://emba.gnu.org/help/user/project/pages/index.md).

Some configuration is required (https://emba.gnu.org/help/administration/pages/index.md).  I don’t know if this has been done for EMBA (but I suspect not, because https://emba.gnu.org/emacs/emacs/pages returns 404; alternatively, it’s possible the feature simply needs switching on at https://emba.gnu.org/emacs/emacs/edit#js-general-project-settings).

Once this is done, you don’t have to do much more than, from your CI job, write HTML files to a directory called pages.

Sounds perfect.

Nice. I'll see whether I can do something useful with this.

Best regards, Michael.

As a starting point, we could use the JUnit reports, which are already
generated. They are not formatted to what we want, but they contain all
test results in XML files for better access.

See for example
<https://emba.gnu.org/emacs/emacs/-/pipelines/31215/test_report> and
click on "Tests". Choose job test-tree-sitter.

There are no data when you inspect "View details", but this can be changed.

Best regards, Michael.

Hmm, ok, it’s a bit unclear to me how do we use this. Anyway, as a first step, I added a command that generates a html file that looks like the below. I’ll try setting up a cron job on my machine, then we can figure out how do we run it on EMBA and how to host the generated webpage.

Peter, do you have any suggestions after seeing this example webpage?
