Hey list,
I am having problems typesetting the following minimal to try and
extract the current revision number from my revision control system:
% Bzr revision...
\def\initializeBzr
{\ctxlua{context("\\global\\edef\\BzrRevision{\%s}",
os.resultof"bzr revno | tr -d '\\n'")}}
\initializeBzr
\starttex
foo
\stoptex
The error I receive is:
! LuaTeX error [string "\directlua "]:1: invalid escape sequence
near '\%'.
system > tex > error on line 5 in file minimal.tex:
LuaTeX error ...
Line 5 is the \initializeBzr invocation. This was working with TeX Live
2012, but perhaps the correct usage has changed. I am now using ConTeXt
2013.04.11 19:55 with LuaTeX beta-0.76.0-2013041612 (TeX Live 2013)
(rev 4627).
Thank you,
PS Please cc me because my subscription is temporarily disabled.

use [[ ]] for passing strings and \letterpercent , of do:
\ctxlua{context.setxvalue("BzrRevision",os.resultof("bzr revno | tr -d
'\string\n'"))}
