Subject: Testing non-existent counter in Lua
Date: Mon, 21 Jun 2010 23:41:14 +0200 [thread overview]
Message-ID: <4C1FDC7A.3040604@gyza.cz> (raw)
Hi, all.
How do I know (due Lua) that the counter has not been defined in ConTeXt
(through the command newcount)?
I am trying testing :
if tex.count.mycount == nil then...
or
if tex.count.mycount == 'error' then...
then when counter isnt defined due \newcount\mycount, then test ending
with error message.
When counter is defined due
\newcount\mycount,
\mycount=1
then test
if tex.count.mycount == 1 then...
is OK...
Thanx, Jaroslav
