! LuaTeX error [string "\directlua "]:1: invalid escape sequence
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).
