Trouble with \placefloat in recent versions of the standalone

Trouble with \placefloat in recent versions of the standalone

Dear all,

With recent standalones (jan. 7, jan. 29 and march 2) I am experiencing trouble processing .tex-files that gave no problems in november (14-11).
For instance, when processing with "ConTeXt  ver: 2013.01.02 18:19 MKIV  fmt: 2013.1.7  int: english/english", the log file gives the following information: 
-------------------------------------------------------------------
! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\s'.

system          > tex > error on line 47 in file Chapter_4_S2MyBq-02-03-example.tex: LuaTeX error  ...
-------------------------------------------------------------------

and further on:
-----------------------------------------------------------------
45     \placeexample[here][ZarlConsCh38p188tot]{Zarlino\index[Zarlino]{Zarlino, Gioseffo}, Consonances ch.38, p.188}
46     {\startcombination[1*2]
47 >>  {\externalfigure[ZarlConsCh38p188fa]}{facsimile}
48     {\externalfigure[ZarlConsCh38p188fi]}{transcription}
49     \stopcombination}
----------------------------------------
The processing stops at line 47.
The log-file's last words are: "<inserted text> ...number \foundexternalfigure ; }"
I have no clue as to what to do with that information.

Just for the sake of completeness: In the setupfile "example" is defined:
\definefloat[example][examples]
\setupcaption[example][way=bychapter,prefix=yes,prefixsegments=chapter,location=top,number=yes,inbetween=\blank,bodyfont=10pt]
\setuplabeltext[en][Example=Ex. ]

As said, "ConTeXt  ver: 2012.11.14 11:37 MKIV  fmt: 2012.11.15  int: english/english" gives no problem at all.
Also, \placetable[here][tab:ref]{caption}} does not seem to trigger problems in recent versions.

Has something been changed in the commands for placing external figures since november?
What would I have to change, either in the setup or in the commands for placing the example?

Thanks in advance for any help.

Best regards,
Robert Blackstone

Hi Robert,

as you got no reply from the others, here’s what I can say:

1. Can you provide a complete, minimal non-working example that
   relies only on the images in tex/context/sample/* ?

2. Maybe your Luatex binary is not in sync with Context. The
   recently included Lua 5.2 is more rigorous with escape
   sequences than its predecessor:

      [12:04:48=>phg@phlegethon=> ~] lua5.1 -e 'print"\s"'
      s
      [12:04:51=>phg@phlegethon=> ~] lua -e 'print"\s"'
      lua: (command line):1: invalid escape sequence near '\s'

   (Where “lua” is the name of the 5.2 binary.) It is possible
   that some leftover files have been loaded when they shouldn’t.
   I would suggest (in this order) to (1) rebuild the format, (2)
   delete the directory “texmf-cache/” in your minimals base dir,
   and, if that all fails, (3) delete “texmf-context/” and re-run
   first-setup.sh.

Regards
Philipp

Hi Philipp,
Thanks for your reply. 
I have as yet not succeeded in making a non-working minimal example. So far they all ran smoothly with each of my whole collection of minimals, including the latest (= yesterday's) beta. 
So I will have to look in some of the auxiliary files, setups etc. for the cause of my trouble. 
The fact remains that the present ConTeXt mkiv is different from that of november and before in a way that is crucial for my project. 

Thanks again. Best regards,

Robert Blackstone

if you see something \s or \x or whatever show up in some lua error you 
probably pass a \macroname in a string argument, so if you can figure 
out where that happens
