Hi list,
there seems to be something wrong with the "escape" mechanism in
verbatim. Line breaks before escaped code are ignored. Consider the
following example from the wiki [1] (e.g. the second line is printed
right behind the first with no line break):
\starttext
\setuptyping[TEX][escape=yes]
\startTEX
/BTEX\em sometex/ETEX
/BTEX\em sometex/ETEX \after
\before /BTEX\em sometex/ETEX
\before /BTEX\em sometex/ETEX \after
\before /BTEX\em sometex/ETEX \inbetween /BTEX\em sometex/ETEX \after
\before \after
\stopTEX
\setuptyping[TEX][escape={[[,]]}]
\startTEX
[[\em sometex]]
[[\em sometex]] \after
\before [[\em sometex]]
\before [[\em sometex]] \after
\before [[\em sometex]] \inbetween [[\em sometex]] \after
\before \after
\stopTEX
\setuptyping[TEX][escape=//]
\startTEX
//\em sometex
\before //\em sometex
\stopTEX
\stoptext
Is this a bug or am I missing something here?
Also "\setuptyping[TEX][escape=//]" seems to have no effect at all, "//"
is printed just like normal chars.
Best regards,
Stefan Müller.

I get newlines here.

Actually in mkii it's
\setuptyping[TEX][escape=/]
\startTEX
/em sometex
\before /em sometex
\stopTEX
and indeed in mkiv it does not work. I will provide a bit of backward
compatibility but keep in mind that in mkiv the \em change will cross
lines, so in this case the first sometex as well as \before will be
slanted.

I'm using minimals: ConTeXt version 2011.01.06 17:08
Just to clarify: My first line in the PDF result is
"sometexsometex \after"

Does that mean the example on the wiki page is not correct?

Thanks and best regards,

Minimal example:
\definetyping[Test][escape={/,/}]
\starttext
No line break between the blas:
\startTest
bla
/bla/
\stopTest
\stoptext

Because of the new beta I tried it again with a current Mk IV version
(2011.01.18 19:34).
The examples I provided (from the wiki, now abbreviated, with numbering)
have correct line breaks but the second line does not get a number.
\setuptyping[TEX][escape=yes, numbering=line]
\startTEX
/BTEX\em sometex/ETEX
/BTEX\em sometex/ETEX \after
\stopTEX
\setuptyping[TEX][escape={[[,]]}]
\startTEX
[[\em sometex]]
[[\em sometex]] \after
\stopTEX
The example from Peter Münster works worse: now there is one line break
more instead of one less. In addition the escaped line does not get a
number as above. It works if the line starts with (non-escaped) text,
space or tab.
\definetyping[Test][escape={/,/}, numbering=line]
\starttext
Two line breaks between the first two blas \\
The second bla does not get a number
\startTest
bla
/bla/
bla
\stopTest
\stoptext
In the examples above there's a difference when using start/stopTEX with
setuptyping[TEX] and when using start/stopTest with definetyping[Test].
I don't know why.
Thank you so far, Hans. Best regards,
Stefan.
