[AUCTeX] Customize tex-ispell.el

[Thorsten Grothe]

Hello,

I would like to add the environment of exsheets to tex-ispell.el,
because it's highlighted as error, the env looks like this:

\begin{question}[skip me}]{skip me}
ispell me please
\end{question}

But I have no idea how to do this. I know the file tex-ispell.el but if
I modify it, it get's overwritten with the next update.

Can anyone help me?

Thanks!

Regards

Thorsten Grothe

Hi Thorsten,

you find a way in the manual how to do this [1]. You can add something
like this to you init file and restart Emacs:

(eval-after-load "tex-ispell"
'(TeX-ispell-skip-setcdr
'(("question" ispell-tex-arg-end))))

Or as a local variable in your .tex file, depending on your use case.

Best, Arash

ah thank you, did not know that. Now I got this construct and it's
working fine:

(eval-after-load "tex-ispell"
'(progn
(TeX-ispell-skip-setcar
'(("\\\\blank\\*?" ispell-tex-arg-end 0)
("\\\\titelbwr" ispell-tex-arg-end 6)
("\\\\addlinespace" ispell-tex-arg-end)
))
(TeX-ispell-skip-setcdr
'(("question" ispell-tex-arg-end)
))))

but I got problems with cmidrules, they are defined in tex-ispell.el but
the regexp seems not to work for this construct:

\cmidrule(lr){2-2}

How can I add this to the above setting? Sorry for the silly question,
but I'm a beginner in regexp :-)

Thanks for the reminder, I've missed that macro from booktabs.sty.
I've just added it. Note that \addlinespace takes only an optional
argument. Hence, this entry should be like this:

("\\\\addlinespace" ispell-tex-arg-end 0)

Which AUCTeX version do you have? Maybe you update to 11.90.2 first.
I tried this nonsensical example and Ispell (I use Hunspell binary) does
the right thing for me:

\documentclass{article}
\usepackage{booktabs}
\begin{document}
Übersetzugn\cmidrule[Übersetzugn](Übersetzugn){1-2}Übersetzugn
Übersetzugn\cmidrule(Übersetzugn){1-2}Übersetzugn
\end{document}

Can you show the entry for \cmidrule from your tex-ispell.el? It used
to be

("\\\\cmidrule" . "\\(([^)]*)\\)?{[-0-9]+}")

but I changed it to

("\\\\cmidrule" . "{[-0-9]+}")

Quoting Jamie Zawinski:

Some people, when confronted with a problem, think "I know, I'll use
regular expressions." Now they have two problems.

Stay away from them, is the best thing you can do ;-)

("\\\\cmidrule" . "{[-0-9]+}")

yes, exactly the same here after updating Auctex and I'm using hunspell
too, but I got problems with german umlauts (ü,ö). I think this is
because hunspell dicts are not coded to utf-8, must find a way to do
that.

Anyway, this entry works fine now:

\cmidrule(lr){2-2}

but this not:

\begin{tabularx}{\linewidth}{@{}>{\sffamily\bfseries}lXX@{}}
5. & & \\\addlinespace[8pt] \cmidrule(lr){2-2}\cmidrule(lr){3-3}
4. & & \\\addlinespace[8pt] \cmidrule(lr){2-2}\cmidrule(lr){3-3}
3. & & \\\addlinespace[8pt] \cmidrule(lr){2-2}\cmidrule(lr){3-3}
2. & & \\\addlinespace[8pt] \cmidrule(lr){2-2}\cmidrule(lr){3-3}
1. & & \\\addlinespace[8pt] \cmidrule(lr){2-2}\cmidrule(lr){3-3}
\end{tabularx}

all cmidrules are flagged red, I think it has to do with tabularx?

Oooh I agree fully with you, regular expression are not the right thing
for me :-) Nice to hear that others make the same experiences :-)

Problem solved, it was because of the entry

("\\\\addlinespace" ispell-tex-arg-end 0)

I added the "0" and now it works!
Sorry for the noise!

I think this is a bug, I got this message:

Spell-checking VWL_Aufgaben.tex using hunspell with default dictionary...done
apply: Symbol’s function definition is void: ispell-tex-skip-alist

my config looks like this:

(eval-after-load "tex-ispell"

(TeX-ispell-skip-setcar
'(("\\\\blank\\*?" ispell-tex-arg-end 0)
("\\\\titelbwr" ispell-tex-arg-end 6)
("\\\\addlinespace" ispell-tex-arg-end 0)
("\\\\pgfplotstabletypeset" ispell-tex-arg-end 0)
;; ("\\\\ID\\*?" ispell-tex-arg-end)
))
(TeX-ispell-skip-setcdr
'(("question" ispell-tex-arg-end)
("kasten" ispell-tex-arg-end)
))))

I first happened with a new env I defined:

\begin{kasten}[\sffamily bla bla}
some text here
\end{kasten}

Then I changed the env to mdframed (the original), that helped, but now I
got the same error and I have no clue where it is. It's a very long
document. With flyspell this does not happen...

Where can I look deeper to find the

With the code above, TeX will complain as well ;-) How do you define
your new environment? If you're using

\newmdenv[<options>]{kasten}

put this in your init file:

(setq TeX-parse-self t)

restart Emacs (without your addition), open you're .tex file, hit `C-c
C-n' and try it again. mdframed.el has some code to add new
environments like "kasten" to ispell skip list, i.e. in
`ispell-tex-skip-alists', you should have an entry like:

("kasten" ispell-tex-arg-end 0)

The length of your .tex document is not relevant for the error message
above; unless you have local variables with lisp code to be evaluated in
your .tex files.

Normal procedure is to start Emacs with `-q' switch, paste your code in
scratch buffer, evaluate it, do `M-x toggle-debug-on-error RET' and
invoke the error and see what Emacs says.

And I can't reproduce what you describe.

no, I do not, I thought that this:

(eval-after-load "tex-ispell"
'(progn
(TeX-ispell-skip-setcar ...

would be the way to solve the issue.

How do you define
your new environment? If you're using

I defined it like so:

\newmdenv[linewidth=2pt,roundcorner=10pt,frametitlerule=true,
frametitlebackgroundcolor=DarkGreen!45,linecolor=DarkGreen!35,backgroundcolor=gray!5,
frametitlerulecolor=DarkGreen!35,frametitlerulewidth=2pt]{kasten}

and used

\begin[bla]{kasten
\end{kasten}

this works for my tex documents and LaTeX runs through without any error
message.

The other thing is that I made a couple of settings in a personal sty
file, the env kasten too.

In the main document I loaded it with \usepackage, this works without
problems. I tried "TeX-auto-generate" for my personal sty file but this
does not help.

Post by Arash Esbati
(setq TeX-parse-self t)

this is in my init since years :-)


It's definitely the new environment kasten what makes problems. I
replaced it with \begin{mdframed} and the error vanishes. I tried this

\newenvironment{kasten}[1]
{\mdfsetup{
frametitle={\colorbox{white}{\space#1\space}},
innertopmargin=10pt,
frametitleaboveskip=-\ht\strutbox,
frametitlealignment=\center
}
\begin{mdframed}%
}
{\end{mdframed}}

and put it in my personal sty file in texmf and ------ it works without
problems. I spellchecked the whole document with no issue. So I guess it
has something to do with my environment definition, strange.

("kasten" ispell-tex-arg-end 0)

tried this too, same effect :-) the old env causes the error, the new
env works fine...

Hi Thorsten,

this is indeed a bug in mdframed.el and I've just fixed it. You can
fetch mdframed.el from AUCTeX repo and use it until the next release.

Again, thank for catching this.

Best, Arash
