Hi, are the delimiters \lgroup and \rgroup supported in MkIV? This
\starttext $$\bigg\lgroup\dots\bigg\rgroup$$ \stoptext
is ok in MkII (ConTeXt ver: 2011.01.06) but when compiled with MkIV (ConTeXt ver: 2010.07.30 11:35 and ver: 2010.07.30 11:35) the delimiters are not shown. (By the way, the same holds true for \rmoustache and \lmoustache.)
Am I missing something?
No. The math mappings of virtual fonts are incomplete. The symbols should work correctly with unicode math fonts like cambria, asana, and xits. But, it appears that lgroup and rgroup are missing from xits (Khaled?)
There are, but context is looking for the wring character; it is looking for U+3014 (which I think is a CJK bracket and does not look like \lgroup either) while it should be looking for U+27EE (whose Unicode annotation precisely says "lgroup"):
\setupbodyfont[xits] \starttext $$\bigg\lgroup\dots\bigg\rgroup$$ \def\lgroup{\Udelimiter "4 "0 "27EE} \def\rgroup{\Udelimiter "4 "0 "27EF} $$\bigg\lgroup\dots\bigg\rgroup$$ \stoptext
It was not extensible though, the version in git now grow, but starts with a relatively large size, check and tell me if it should be smaller.
Looks OK to me, but I am not really an expert on the shapes of the symbols. Can you also make lmoustache and rmoustache extensible?
Hans, I am attaching the patch for char-def.lua that corrects the location of lgroup and rgroup. I still do not know how to fix this for lm virtual math font.
