Add conceal for \lvert, \rvert...

[Freed-Wu]

Describe the solution you'd like

e.g.

syntax match texMathSymbol "\\lvert"               contained conceal cchar=|
syntax match texMathSymbol "\\lVert"               contained conceal cchar=ǁ
syntax match texMathSymbol "\\rvert"               contained conceal cchar=|
syntax match texMathSymbol "\\rVert"               contained conceal cchar=ǁ

test

$$\lVert \mathrm{w} \rVert_2^2$$

[lervag]

Done.

A package named physics provide the macro \abs{w} and \norm{w} to wrap \lverb w\rverb and \lVerb w\rVerb. Can them be concealed like \verb? Thanks!

[Freed-Wu]

And I think

syntax match texCmdAccent   "\\i\>"  conceal cchar=ı
syntax match texCmdAccent   "\\j\>"  conceal cchar=ȷ

is correct, just like \O and \o.

[Freed-Wu]

How about

syntax match texCmdAccent   "\\lq\>"  conceal cchar=`
syntax match texCmdAccent   "\\rq\>"  conceal cchar='

? Maybe punctuations can be concealed.

I assume you mean \vert here? This is somewhat harder to do. I know a method, but is really quite hacky. I think it may be better to not go there...

[Freed-Wu]

Oh, I see. Vim' conceal seems to be able to support only one character. Thanks!

[lervag]

Yes, precicely. I could conceal the initial \abs{ and the suffix } individually, but the matching is then more complex and error prone. So I'm not sure if it is worth the effort.

[Freed-Wu]

I found \backslash has been concealed to \ in math mode. How about concealing \slash to /? It can work in non-math mode and math mode.

[lervag]

Yes, no problem. I've added it as a "fancy" conceal.

[Freed-Wu]

In tex,

`'

``''

!`

?`

will output

‘’

“”

I notice double quotes has been concealed in vimtex:

" autoload/vimtex/syntax/core.vim:1832-1833
syntax match texLigature    "``"     conceal cchar=“
syntax match texLigature    "''"     conceal cchar=”

How about others?
