LuaTeX error <main ctx instance>:1: '<name>' expected near '\'.

[Peter Münster]

Hello,

With the latest version, I get the following error:

This is the file c-course-vimsyntax.tmp-vimsyntax.tmp:

\s[]{printf(}\s[Constant]{{\letterdoublequote}0x}\s[Special]{{\letterpercent}lx}\s[Special]{{\letterbackslash}n}\s[Constant]{{\letterdoublequote}}\s[]{,
ul);}


I get this error, when compiling my product. When components are compiled
one by one, there is no such error.

I use pre-stepwise. Without this module, there is no such error.

I would like to help, finding the reason for the problem, but the last
time, I've spent more than 2 hours to build a minimal example.
So, I would be glad, if there are other, not so time consuming ways, to
track down the problem.

If there is no other way, I'll build a minimal example of course.

TIA for any hints!
Cheers, Peter

my guess is that t-vim is doing something funny with catcodes and that 
can interfere with pagebreaks and the pagebuilding

normally codes are reset when the otr is invoked

so, indeed we need a small example

maybe just something

\starttext

\start \initializevimmode

\input that temp file that has multiple pages

\stop

\stoptext

Hello Hans,

Finally it took me less time. Here is it:

\usemodule[pre-stepwise]
\def\startC{%
  \bgroup
  \whitespace
  \obeylines
  \activatespacehandler{yes}%
  \strut}
\def\stopC{\egroup}
\setupinteraction[state=start]
\setuppapersize[S6][S6]
\setupwhitespace[big]
\starttext
\startcolumns\placelist[chapter]\stopcolumns
\startC
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
\stopC
\stoptext

Cheers, Peter

the problem, is that the catcodes are changes in the main vector and 
that influences code handled in the output routine

there is no easy way around this (apart from not switching catcodes)

so, after figuring out that in this case the prooblem is in delayed 
expansion of

\definereference [CheckStepper]  [JS(CheckStepper{\StepCounter})]

i decided to add a push/popper, which works like this

\def\startC
   {\bgroup
    \pushcatcodes
    \whitespace
    \obeylines
    \activatespacehandler{yes}%
    \strut}

\def\stopC
   {\popcatcodes
    \egroup}

of course this is only needed when changes to catcodes are made that 
bleed into the page builder (happens seldom)
