This works:

\starttext
\the\catcode`|
\pushcatcodetable
\catcodetable\prtcatcodes
\catcode`|=12
\popcatcodetable
\the\catcode`|
\stoptext

(Note that under \prtcatcode, the catcode of | is 12). 
But replacing \prtcatcodes with \ctxcatcodes does not work.


So, one "proper" fix may be add a new catcodetable, say \tikzcatcodes, for 
all the catcode changes that tikz does.

mkiv gives 13, and 12.
mkii gives 13, and 13.

It would also make sense to ask about the proper patch for TikZ, so
that we could push the patch upstream.

What is the easiest way to fix this (without patching tikz)?
Ensure that | has always the same catcode in math mode independant of 
the catcode in text mode like _ and ^.

I thought that

\pushcatcodetable
\usemodule[pgfplots]
\usepgfplotslibrary[fillbetween]
\popcatcodetable

should work, but it does not. Why?

Surrounding by \unprotect ... \protect does work, so I am wondering 
what is the difference between the two?
When you use \unprotect … \protect context changes the catcode table 
between the group but when you only use push and pop this isn’t the case.

Hi,

The following example fails:

\usemodule[pgfplots]
\usepgfplotslibrary[fillbetween]

\starttext
\startformula
  \left. a \right|
\stopformula

\stoptext

with

tex error > tex error on line 7 in file /private/tmp/test.tex: ! Missing 
\endgroup inserted



\endgroup

\Ucheckedstopdisplaymath
\stopdisplaymath ...math \Ucheckedstopdisplaymath
  \par \ifvmode \ifcase 
\c_s...

\strc_formulas_stop_formula ...native \v!formula }
  \dostoptagged 
\dostoptagge...

l.7 \stopformula

This is a weird bug. Only \left. \right| fails; \left| \right| works 
correctly. If I remove the fillbetween library, the error goes away.


Any hints as to what is happening will be appreciated.


The fillbetween library changes the catcode of the bar character.

\starttext

\the\catcode`|

\usemodule[pgfplots]
\usepgfplotslibrary[fillbetween]

\the\catcode`|

\stoptext


Thanks!

You get the same error when you use \asciimode in your document.

\asciimode

\starttext

\startformula
  \left. a \right|
\stopformula
