Add and remove multi-line line comments

[bbarker]

I'm pretty new to helix so apologies for likely missing something obvious, and it's ok by me if this ability doesn't exist yet, but wanted to check:

Say i have some code:

fn json_pointer_to_value<'a>(json: &'a Value, pointer: &str) -> Option<&'a Value> {
    pointer.split('.').try_fold(json, |acc, part| match acc {
        Value::Object(map) => map.get(part),
        _ => None,
    })
}

and I want to comment out some lines so it looks like

fn json_pointer_to_value<'a>(json: &'a Value, pointer: &str) -> Option<&'a Value> {
    pointer.split('.').try_fold(json, |acc, part| match acc {
        // Value::Object(map) => map.get(part),
        // _ => None,
    })
}

Then i'd like to be able to select those lines and get back to the original (uncommented) state. What are the ways one can achieve this presently, if any?

Select them both (maybe use x) and press the toggle comment shortcut:

[keys.normal]
"#" = "toggle_comments"

My brain forgot the default on purpose as it was not good :)

You can select both and press it again and hey presto they are uncommented!

There is PR to do proper multi line block comments in the works: #4718

The current default keybinding is C-c

[David-Else]

Ctrl-C sends an interrupt signal (SIGINT) to the current process running in the foreground in the terminal, no wonder I rejected outright the idea of using that for toggling comments... 99% of decisions in Helix are perfect, but that one was goofy as hell. I think the new PR will have it as space c which will be fine :)

[pascalkuthe]

the idea is based on vim (the shortcut is pretty universal among comment plugins there). I do personally prefer it on pound (#)

[themixednuts]

Is there actual multiline comment support and not multiple single line comments?

As well as something of the equivalent for Svelte files and such (https://github.com/JoosepAlviste/nvim-ts-context-commentstring)
