syntax conceal for spacing commands

[pburger24]

request to apply the syntax conceal feature to LaTeX spacing commands such as \quad, \qquad, \,, \thinspace, \:, medspace, ;, \thickspace, \!, \bigskip, \vskip, \vspace, \hspace, \vfill, \hfill

[lervag]

This is more or less already supported. There are probably some exceptions, but at least \quad and \, and similar should already work. The following are not implemented now:

• \thinspace
• \medspace
• \thickspace
• \bigskip
• \vskip
• \vspace
• \hspace
• \vfill
• \hfill

I could add these, but before I properly consider it, please help me by categorizing the commands:

1. Do they work in math or normal mode?
2. Are they part of the "core", or do they come from a specific package?

[pburger24]

u mean like do they come from a latex package?
\\: , \\medspace, \\;, \\thickspace, \! all come from amsmath

[pburger24]

the reset r not from a package

[pburger24]

i haven't noticed , working or \quad, and i just fetched

[lervag]

I'm sorry, but could you please write in full sentences? I do not understand what you write in the last comment.

Proof that the conceals work as expected for some of these:

Here you see that \quad and many of the other symbols are concealed (on the right-hand side). The left-hand side has set conceallevel=0. However, \medspace, \thickspace and similar are not concealed yet.

In any case, I've investigated and reached the following conclusion:

1. I will not add conceals for the vertical variants. These are more important in a context and should not be concealed (IMHO).
2. I will implement support for the other variants. It is true that amsmath does provide some of these, but only in the sense that it improves them. The following minimal example compiles and works as expected without loading amsmath:

\documentclass{minimal}
\begin{document}

Hello
\thinspace
\medspace
\thickspace
\bigskip
\hspace{1em}
\hfill
\vspace{1em}
\vfill
Moon

1 \, \: \; \! \quad \qquad 2

$ 1 \, \: \; \! \quad \qquad 2 $

$
Hello
\thinspace
\medspace
\thickspace
\bigskip
\hspace{1em}
\hfill
\vspace{1em}
Moon
$

\end{document}

Some of this, as mentioned before, already works. But I'll implement the missing parts as well.

[lervag]

Done. It should work as expected now, I believe.

[pburger24]

after fetching, it still didn't conceal , or \quad , it just highlighted them.

Then that's because you have some issue with your configuration.
