Indentation left/right #3023

Closed switzel closed 1 week ago

switzel commented 1 week ago

Description

I'm 90% sure that this is within the responsibility of vimtex, if not please tell me.

When I autoindent (=) a (la)tex file involving $\left. \right|$ the following lines pick up an extra indentation. The left symbol can be replaced by other things but apparently the \right| does not "close" it.

Steps to reproduce

Put the code

noindent
$\left. \right|$
indent

into a file minimal.tex. Type gg=G. It gets indented as

noindent
$\left. \right|$
  indent

(actually it is indented already while typing). (Github won't let me upload a .tex file.)

Expected behavior

The expected indentation is

noindent
$\left. \right|$
indent

Actual behavior

The indentation vimtex produces is

noindent
$\left. \right|$
  indent

Do you use a latexmkrc file?

No

First, a friendly warning: You are using an old Ubuntu on which the Vim version is also old. I am quite close to only supporting Vim version 9.1.

I'm 90% sure that this is within the responsibility of vimtex, if not please tell me.

When I autoindent (=) a (la)tex file involving | the following lines pick up an extra indentation. The left symbol can be replaced by other things but apparently the \right| does not "close" it.

The problem is that the bar symbol | is very hard to match and that it is not really suitable for use as a delimiter. In your case, it will work if you instead use the \rvert, and this is the proper solution here. See e.g. this tex.stackexchange.com question where the answer should be elucidating.
