[BUG]: The comment_string of some filetypes will contain trailing space

[MasouShizuka]

Take the CBllbox command as an example.

In the python file,
before:

# test

after:

#  ╭──────────────────────────────────────────────────────────╮
#  │ fuck                                                     │
#  ╰──────────────────────────────────────────────────────────╯

The comment_string is # .

In the lua file,
before:

-- test

after:

--  ╭──────────────────────────────────────────────────────────╮
--  │ test                                                     │
--  ╰──────────────────────────────────────────────────────────╯

The comment_string is -- .

In the rust file,
before:

// test

after:

// ╭──────────────────────────────────────────────────────────╮
// │  test                                                    │
// ╰──────────────────────────────────────────────────────────╯

The comment_string is //, and does not contain space.

It can be seen that some filetypes are separated by 2 spaces, and some are separated by 1 space.
In the former, I found that it contains space by printing comment_string, such as # in Python.

Is there something wrong with my configuration?

Also, I think this can be used as a configuration item, that is, the number of spaces between comment and box.
0 means no spaces, etc.

I obtain the same results as yours. I use the built-in vim.bo.commentstring to determine the comment_string and it seems that this command doesn't give a consistent/accurate result or I'm missing something, in the former I'm afraid I can't do much about it. A better and definitive solution would be to use a table of the possible comment types as Comment.nvim does but I looked into it and it's beyond what I'm capable to accomplish with my poor understanding of lua, regex and the nvim api right now ^^

For your suggestion to configure the number of spaces between the start of the box and the comment (am I understanding correctly?) I will look into it.

Thanks for your feedback!

Just found a workaround while working on another issue (I just had to trim the comment_string after retrieving it). It should work consistently with all filetypes now.

I close this issue but I keep in mind your suggestion. Thanks again for your feedback!

Lines still have redundant spaces.

In the python file:

#  ────────────────────────────────────────────────────────────
# ╭──────────────────────────────────────────────────────────╮
# │ test                                                     │
# ╰──────────────────────────────────────────────────────────╯
#  ────────────────────────────────────────────────────────────

By the way, there seems to be a small error in the readme?

[LudoPinelli]

You're right in both cases! Should be fixed now. Thank you!
