can't get the extension to do anything on a rust file...

[SpamapS]

Hi! I was really excited to find rewrap in the vs:code extensions to replace my vim habit of gq'ing comments.

But I can't get it to do anything.

I'm on Ubuntu 22.04, with VS:Code 1.73.1, and rewrap 1.16.3

I have pasted this year's advent of code day one into a block comment in a rust file and it just does nothing whether I turn on auto wrap or press the assigned keybinding. I tried changing it from alt-q to shift-alt-q and still it does nothing. Here's the exact text I have selected:

/*
--- Day 1: Calorie Counting ---

Santa's reindeer typically eat regular reindeer food, but they need a lot of magical energy to deliver presents on Christmas. For that, their favorite snack is a special type of star fruit that only grows deep in the jungle. The Elves have brought you on their annual expedition to the grove where the fruit grows.

To supply enough magical energy, the expedition needs to retrieve a minimum of fifty stars by December 25th. Although the Elves assure you that the grove has plenty of fruit, you decide to grab any fruit you see along the way, just in case.

Collect stars by solving puzzles. Two puzzles will be made available on each day in the Advent calendar; the second puzzle is unlocked when you complete the first. Each puzzle grants one star. Good luck!

The jungle must be too overgrown and difficult to navigate in vehicles or access from the air; the Elves' expedition traditionally goes on foot. As your boats approach land, the Elves begin taking inventory of their supplies. One important consideration is food - in particular, the number of Calories each Elf is carrying (your puzzle input).

The Elves take turns writing down the number of Calories contained by the various meals, snacks, rations, etc. that they've brought with them, one item per line. Each Elf separates their own inventory from the previous Elf's inventory (if any) by a blank line.

For example, suppose the Elves finish writing their items' Calories and end up with the following list:

1000
2000
3000

4000

5000
6000

7000
8000
9000

10000

This list represents the Calories of the food carried by five Elves:

    The first Elf is carrying food with 1000, 2000, and 3000 Calories, a total of 6000 Calories.
    The second Elf is carrying one food item with 4000 Calories.
    The third Elf is carrying food with 5000 and 6000 Calories, a total of 11000 Calories.
    The fourth Elf is carrying food with 7000, 8000, and 9000 Calories, a total of 24000 Calories.
    The fifth Elf is carrying one food item with 10000 Calories.

In case the Elves get hungry and need extra snacks, they need to know which Elf to ask: they'd like to know how many Calories are being carried by the Elf carrying the most Calories. In the example above, this is 24000 (carried by the fourth Elf).

Find the Elf carrying the most Calories. How many total Calories is that Elf carrying?

I am using the rust-analyzer extension and the only other thing in the file, which is named main.rs, is the default main block that is created by cargo new --bin

I just noticed when I went back to my editor it had this error, maybe related:

Error loading webview: Error: Could not register service workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..

I believe Rewrap just doesn't support block comments in Rust. I tried changing the language of a Rust file to C, and rewrap worked fine.

For now the only solution is either to do that, or to use a block of single-line comments, i.e. //.

I would also change the title of this issue to something like Support for Rust block comments as that's more descriptive of the problem.

Recommended title: Add support for wrapping block comments in Rust files.

In my case (except for normal // coments) it does nothing for all Rust code.
Lines like these are not re-wrapped.

fn a_long_function_signature<'a, T>(string_a: &'a str, string_b: &'a str, ann: T) -> &'a str

let chained_expressions="very long"; let char_list = vec!['y', 'm', 'a', 'q']; let largest = get_max(char_list); println!("largest {}", largest);

let long_vector = vec![34, 50, 25, 100, 65, 34, 50, 25, 100, 65, 34, 50, 25, 100, 65, 34, 50, 25, 100, 65];

"A very looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong string"

/* A very looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong comment */

Maybe I'm missing something.
