Hello,
Pleeease, I need a help.
I might formulate my previous question badly, so let me restate it.
How to handle optional arguments (one or two) with \definestartstop? More specifically, how to replace hard-coded "Logging-On" string so that I could write \startusecase[Logging-Out] Bla-bla \stopusecase
or even
\startusecase[Reminding password][User should be already logged on] % where the last argument is completely optional and is shown on an additional line % with "prerequisite" mark Bla-bla-bla \stopusecase
AFAIK startstop doesn't support optional|additional arguments. But maybe I'm wrong or there is a better fitting macro somewhere in the deep of 'the base'. I simply dunno. Anyhow, this is what I would do in such a case \def\startFOO{\dodoubleempty\dostartFOO} \long\def\dostartFOO[#1][#2]#3\stopFOO{% \iffirstargument [do something with #1] \else [do something without #1] \fi \ifsecondargument [do something with #2] \else [do something without #2] \fi [whatever before] #3 [whatever after] } \let\stopFOO\relax % or define the [whatever after] stuff here This is the basic construct, the rest is parameter evaluation and some additional whatever. HTH, Peter
My current startstop definition is
\definestartstop[usecase][before={\starttextrule{Use Case: Logging-On}\startpacked\startmypar{\bf User Intentions}\mypar{\bf System Responsibilities}\stopmypar}, after={\stoppacked\stoptextrule}]
Best, Vyatcheslav
