Hi Hans,
is there a simple way to change the status from commands created with
\newconditional id \newif from, e.g. in the following example it’s easy to pass
the value of the conditional from TeX to Lua but not in the reverse way.
if tex.conditionals.whatever ...
Is there also a lua version of \settrue and \setfalse or \…true and \…false
(because i saw the “tex.ifs” metatable)?
we can add tex.settrue ... but I think that we should get rid of \if...
as much as possible
\starttext
\newconditional\TestConditional
\startluacode
function tex.settrue(name)
tex.count[name] = 0
end
function tex.setfalse(name)
tex.count[name] = 1
end
-- tex.settrue("TestConditional")
\stopluacode
\ifconditional\TestConditional
YES
\else
NOP
\fi
\stoptext
I'll add the two definitions.
Hans
