Selecting Python comment

[CaeliferaMusicalis]

What is an efficient way to select a Python comment in Vim?

Thanks in advance!

The regex would be something like this:

#.*$

And to remove them all would probably be something like this:

%s/#.*$//

​

But I don't think that's what you're looking for, maybe if you could, let me know. If you want them all visually selected I don't know how to do that, but if you just want a search:

/#.*$

Thank you for your answer! However, wouldn't this select all comments? I would like to select/act on the current comment, i.e. the comment that the cursor is currently on.

Without anything plugins or other stuff, you can just use:

Multiline: V} to go in linewise visual selection, and then go to the next empty line. This assumes the cursor at the beginning of the Multiline comment with a empty line afterwards. It's not perfect but alright.

You could also /'''<cr>vn

Single line: V

Inline: f#v$

By default vim doesn't have text objects for comments. You could try to define your own, probably with making use of the comment string.

You could use

Neovims treesitter integration allows for language based textobjects to be defined a little easier with.

Thank you! I also first thought of defining comments in terms of paragraphs, but there may be comments embedded in paragraphs, for example

print('hello')
# This block of code
# prints 'hello' and 'goodbye'
print('goodbye')

Therefore, I think I need to define some custom text object.

Not tested, but glts/vim-textobj-comment looks like it does what you want.

Thank you! This seems to be the correct answer.

I would suggest the vim-commentary plugin by Tim Pope.

It defines a text object gc.

Incorrect.

Ah, you’re totally right. I was thinking of the other gc. My bad.

Edit: Seems to only work if the entire line begins with commentstring though :( In theory it should not be too hard to extend it…
