Examples
Example 1: Date Macro
\startTEXpage[offset=5mm] %--- Commands Needed %\setvariable{NAME}{KEY}{VALUE} => \getvariable{NAME}{KEY} %\defineexpandable[n] %\doifnumberelse{TEXT}{TRUE_CASE}{FALSE_CASE} \defineexpandable[1]\notToday{% \start\dorecurse{#1}{\increment\normalday}\currentdate\stop% }% \defineexpandable\Date{% \doifnumberelse{\getvariable{Document}{Date}}{\notToday{\getvariable{Document}{Date}}}{\currentdate}% }% \setvariable{Document}{Date}{today} Today is \Date. \setvariable{Document}{Date}{7} In a week will be \Date. \stopTEXpage
Example 2: Using Lua
We can also write tests using Lua. (Example by WS, 3/2011.)
\startTEXpage \ctxlua{test = true} Test is \ctxlua{commands.doifelse(test)}{True}{False}. \ctxlua{test = false} Test is \ctxlua{commands.doifelse(test)}{True}{False}. \stopTEXpage
