feat: with stdin and quiet mode

[kjuulh]

Adds quiet and stdin mode, which are useful when integrating with text mode
editors, such as neovim with null-ls.

The code is a bit messy, I could refactor it, but I wanted to see if this was
something you would be interested in

Hey, thanks for your contribution!

Did you know there is https://github.com/bram209/leptos-language-server as well?

Also, leptosfmt currently only formats the view! macro, not the code around it. I wonder if it would make sense to add the option to run rustfmt before formatting the view macro, so that leptosfmt could be set as the default formatting tool for rust analyzer (see the rust-analyzer.rustfmt.overrideCommand configuration option)

Anyway, this looks good so far, I would gladly merge this feature, am currently traveling so will review when I get back home.

Nope, I will check it out and get it added to Mason if possible :D.

For the second thing, I basically just run the leptosfmt null-ls command first, and then the rust-analyzer rustfmt second. This is done because locally I just use:

        nls.builtins.formatting.rustfmt.with({
          extra_args = { "--edition=2021" },
          filetypes = { "rust" }
        }),
        leptosfmt.with({
          condition = function(utils)
            return utils.root_has_file({ "leptosfmt.toml" })
          end,
        }),

Which only enables leptosfmt if there is a config file, this prevents it from running for arbitrary rust files which doesn't have leptos deps.

It could make sense to wrap the rustfmt in leptos, but it seems a bit hacky and would make onboarding to the tool maybe a bit steeper. I.e. that people would have to disable the normal rustfmt when using leptos. That said it could be an easier option.

And I am not in a hurry so take your time. I will continue to use my own fork until then =D

This is basically a "format utf8 encoded bytes" method, as the formatter crate is not aware / does not care if it comes from stdin or not.

I think I prefer to export format_file_source (pub use format_file_source in lib.rs) and then calling that from the CLI crate, agree?

[bram209]

you can use read_to_string here: https://doc.rust-lang.org/stable/std/io/trait.Read.html#method.read_to_string

Just saw the review comments. I will update with revisions etc. I should get around to it in a few days or so =D

I am very interested in this functionality as well, so just a drop by comment

Should these just be of type bool and remove the default_missing_value? Right now it panics if stdin and quiet is not provided as flags. It would also allow to type --stdin instead of --stdin=true which just is redundant IMO

I also feel like quiet should be default to true if stdin is true

[kjuulh]

Yep. I agree. I will definitely change it to proper flags when I get around to fixing it xD
