Hi, Wolfgang.
I tried dropping in the Lua code, but it does not extract the text:
\define[1]\StyleChapter{%
\StyleChapterFramed{%
\framed[align=right, frame=off]{%
\startoverlay
\color[ColourSecondaryLightest]{%
\cldcontext{string.sub(#1,0,1)}
}
\vskip-1.9em\hskip1.2em#1
\stopoverlay
}
}
}
! LuaTeX error [string "\directlua "]:1: bad argument #1 to 'sub' (string
expected, got nil)
I've tried a few variations:
\directlua{string.sub(tex.sprint("\luatexluaescapestring{#1}") }
\directlua{string.sub("\luatexluaescapestring{#1}",0,1)}
\directlua{string.sub(tex.sprint("#1"),0,1)}
\cldcontext{string.sub(tex.sprint("#1"),0,1)}
Any ideas?
