Hi Peter,

I recommend using the following handy little idiom: \ctxlua{commands.doifelse(-45 > 0)}{big}{small} % small

It lets you do all sorts of things that are tricky in TeX: \ctxlua{ commands.doifelse( string.len( "-45" ) > 5 ) }{long}{short}

Cheers, Sietse

For functions in the commands namespace you can write e.g. \ctxcommand{doifelse(…)}{…}{…} instead of \ctxlua{commands.doifelse(…)}{…}{…}. Wolfgang
