bug#74461: [PATCH] Add go-work-ts-mode

[Gabriel Santos via Bug reports for GNU Emacs, the Swiss army knife of text editors]

[-- Attachment #1: Type: text/plain, Size: 1108 bytes --]

Greetings,

I wrote a tree-sitter mode after founding there wasn't one for Go
Workspace files. I'd like to say thanks to Randy Taylor on his work to
the Go tree-sitter mode, helped me a lot in this process.

Commit message:

* admin/notes/tree-sitter/build-module/batch.sh:
* admin/notes/tree-sitter/build-module/build.sh: Add go-work support.
* etc/NEWS: Mention go-work-ts-mode.
* lisp/progmodes/eglot.el (eglot-server-programs): Add go-work-ts-mode.
* lisp/progmodes/go-ts-mode: Add go-work-ts-mode for working with
workspace files.

The parser can be found here:
https://github.com/omertuc/tree-sitter-go-work

And I tested changes locally with a package:
https://github.com/gs-101/go-work-ts-mode

Issues that could be found:

- Some syntax highlighting might be unecessary (ERROR face)
- The grammar might be outdated (I found no issues when testing)
- Eglot addition might be unecessary
- Grammar elements could be missing (I checked both grammar.js and
- grammar.json, and only found the keywords added here)

I will mail my copyright assignment to the FSF still today.

Regards,

-- Gabriel Santos

The last sentence is factually inaccurate: the user needs to load
go-ts-mode to have this mode auto-enabled, right?

> +(defun go-work-ts-mode--in-directive-p ()

"inside a go-work directive", I presume?  IOW, the doc string's first
sentence sounds too general.

> +(if (treesit-ready-p 'gowork)
> +    (add-to-list 'auto-mode-alist '("/go\\.work\\'" . go-work-ts-mode)))

Wouldn't it be better to have this in the default value of
auto-mode-alist, just conditioned by (treesit-ready-p 'gowork) ?  That
way, loading go-ts-mode will not change auto-mode-alist.

Stefan, WDYT?

Tree-sitter modes are not listed where we have other modes for the
same files, to avoid breaking past behavior.  I don't think this
danger is relevant to go.work files, but let's see what Stefan thinks
about that.

The latter.  Using the same thread keeps all the discussions recorded
as part of the same issue number, which is good for future reviewing
of the discussion.  For the same reason, please don't edit the Subject
of the responses, so that they all keep the same Subject.

Thanks.

Thanks, got it. I didn't reply to all because the last e-mail was sent
from my phone. This one is from Emacs, and I added the following to the
header (before the e-mail body):

To: eliz@gnu.org
Cc: 74461@debbugs.gnu.org
Subject: Re: bug#74461: [PATCH] Add go-work-ts-mode

Let me know if I made any other mistakes in this e-mail.

Thanks, I used the current subject for this e-mail now.

Also, attached is the rebased commit featuring the changes you
requested. I also went ahead and clarified the documentation for
`go-mod-ts-mode--in-directive-p', to make it less generalized.

Through this contribution, I think I'll get more comfortable with the
e-mail workflow, and end up contributing more here. My next one would be
mentioning the parser URLs in the other tree-sitter modes. treesit-auto
(https://github.com/renzmann/treesit-auto) has a collection of them, so
this shouldn't be particularly difficult.

Users can disable this if they desire.

I think it's fine.

Copy paste error ("gowork" instead)?

It would be nice to have syntax highlighting and indentation tests for
this (ideally covering everything). If you're interested, take a look
at go-ts-mode-tests.el and the files it references for inspiration.

I fixed the mistake you pointed out in build.sh

I wrote some simple tests for both go-mod-ts-mode and go-work-ts-mode.
For syntax highlighting, I had them both use the same file
(font-lock-package.go), since they have some compatible elements, and
for indentation, I made a simple test for indenting multiple lines.

I also changed the face for operators (on go-work-ts-mode), as I
incorrectly used font-lock-warning-face.

Also, please let me know your opinion on how I layed out the grammars in
the commentary section. I think I'll go through the other tree-sitter
modes and add the grammar to their commentary section too, so it's nice
to get some feedback before making these changes.

The patch LGTM, but if you have a later version, please post that.

The only comment I have is that for the commit log message:

> * lisp/progmodes/go-ts-mode: Add go-work-ts-mode for working with
> workspace files.
> * lisp/progmodes/go-ts-mode: Add the repositories for the grammars to
> the commentary section.
> * lisp/progmodes/go-ts-mode (go-mod-ts-mode--in-directive-p): Be more
> specific on the directive location.

These should mention the file name only once, and they all should
mention the names of functions/variables where the changes were made.
For new functions, just list them and say "New functions."

Also, the lines in the log message are too long: they should
preferably be at most 64 columns, and never more than 70.

How is your copyright assignment paperwork going?  I don't think I saw
any responses from the FSF copyright clerk; if more than 2 weeks have
passed since you emailed the assignment form, please ping them and CC
me.

Thanks.

Thanks, got it, I broke down some of the lines,
longest one is at 54 columns.
Both vc and Magit have functions for adding logs to commits,
really useful:

- log-edit-generate-changelog-from-diff
- magit-commit-add-log

It has been a week since my first e-mail,
and five days since the second one.
I'll add a agenda entry for this to ping and CC you at 2024-12-09
(2 weeks and 2 days since the first e-mail).

> Thanks.

My pleasure, wouldn't be able to contribute to this great software
without all of the previous work of you and other maintainers and
contributors.

Do we have a way to tell Eglot which LSP server(s) to use via some
buffer-local var, instead of having to change this centralized
"database"?

I'd use 3 or more semi-colons here, so it acts as a section separator.

The "4" above is weird since there's no "3".  Similarly, the use of "b"
is a bit odd since the "normal" comment is unused.

This docstring doesn't seem right: the function returns another
function, not a boolean.

AKA (member (treesit-node-type (treesit-node-at (point))) '("replace" "use"))

Why not use the standard name for the syntax-table (in which case you
don't even need this `:syntax-table` argument)?

Is this `indent-tabs-mode` setting required by the definition of the
go.work syntax/language, or is it a personal preference?  If it's
a personal preference then it doesn't belong in the major mode, and if
it's required by the syntax, then say so in a comment (ideally with
a URL pointing to the relevant part of the language definition).

> +(if (treesit-ready-p 'gowork)
> +    (add-to-list 'auto-mode-alist '("/go\\.work\\'" . go-work-ts-mode)))

Since we don't have another (non-treesitter) mode for these files, I'd
recommend you go straight for:

    ;;;###autoload
    (add-to-list 'auto-mode-alist '("/go\\.work\\'" . go-work-ts-mode))

Looking at the following commits:

That doesn't seem to be the case.

I think 4 would be better in this case.
That would make these comments sub-sections

Huh, that is true (it returns a lambda function).
Thankfully Randy is CC'ed here, so maybe
he can comment on that.

Thanks, It works. I'll also update the workspace function.

That's how it's done in the workspace
configuration,
but I removed it for work now
and testing by using treesit-explore
on the grammar's corpus shows nothing
out of the elements there.

Thanks again.

Go uses tabs for indentation,
and spaces for alignment.

This is valid even for workspace files,
as adding more than one package modifies
the use directive to multiple lines
indented with tabs.

<https://0x0.st/8r82.png>
(tabs added by running go work use, not by me)

<https://go.dev/doc/effective_go#formatting>

<https://pkg.go.dev/cmd/gofmt>

The language specification doesn't mention
that, but I think it should.
Maybe I should send them an e-mail about that.

<https://go.dev/ref/spec>

Sorry if I misunderstand,
but that doesn't seem to be the case
for other tree-sitter modes.

See rust-ts-mode for instance:

<https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/rust-ts-mode.el?id=59367f6a3a9dd7fb30429494b622ebdec94e6e32>

The non-treesitter mode for this language is an external package.

And Elixir too:

<https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/elixir-ts-mode.el?id=59367f6a3a9dd7fb30429494b622ebdec94e6e32>

Seems like we need further conversation on this topic.

I'll make the changes you requested and send the updated patch after I'm done.

I just finished updating the patch,
but I think it's best to only send it after
the point about *--in-directive-p is clarified.

It was a kind of rethorical question: whether we do or not, we *should*
have such a mechanism and we should use it here.

I don't think the language cares (or should care).  It's only a convention.
But if it's the only convention in use in Go, that's fine: just add
a link to https://go.dev/doc/effective_go#formatting that justifies
the setting.

Past practice does not always reflect best practices, especially when
talking about relatively new practices.

Oh definitely, another point for discussion.

I added it to the commentary section:

+;; Go uses tabs as a convention for indentation:
+;; https://go.dev/doc/effective_go#formatting
+;; so indent-tabs-mode is enabled for the modes.

>>>Since we don't have another (non-treesitter) mode for these files, I'd

I'll change that, but after this is accepted
I'll make this change to the other modes,
CCing emacs-devel and the respective maintainers.

I got an e-mail back from the copyright clerk yesterday.

(This e-mail is from that same day, 2024/12/17. There was an error with
my mail client.)

My copyright is now signed!

I'll check first if there are any major changes related to tree-sitter
that I should update the patch too.

Regards,

so unless there's additional comments from Stefan this can be merged.

Sorry for my delay on this,
I had issues with multiple mail clients not delivering mail.

Hopefully this messages actually reaches

Please rebase the patch on the current master branch and post the
result, with the commit log message.  Then we can install this.

Thanks.
