[NTG-context] Argument of \startInvoice has an extra }.

2013-11-09 Thread Peter Münster 
Hi,

How could I avoid that error here please:

--8---cut here---start-8---
\def\beginInvoice{\dosingleempty\dobeginInvoice}
\def\dobeginInvoice[#1]{\grabbufferdata[myLetter][beginInvoice][endInvoice]}
\def\startInvoice#1\stopInvoice{bla}
\starttext
\beginInvoice
\startInvoice test \stopInvoice
\endInvoice
\stoptext
--8---cut here---end---8---

TIA for any help,
-- 
   Peter

One possibility is to restrict optional arguments to one line:

\def\beginInvoice{\bgroup\obeylines\dosingleempty\dobeginInvoice}
\def\dobeginInvoice[#1]{\egroup\grabbufferdata[myLetter][beginInvoice][endInvoice]}

Thanks. How did you find the reason for the error (and the solution)?

Is there also a solution with support for multiple lines? Unfortunately
this does not work:

--8---cut here---start-8---
\def\beginInvoice{\bgroup\obeylines\dosingleempty\dobeginInvoice}
\def\dobeginInvoice[#1]{\egroup\getparameters[PRM][#1]%
  \grabbufferdata[myLetter][beginInvoice][endInvoice]}
\def\endInvoice{\getbuffer[myLetter]}
\def\startInvoice#1\stopInvoice{#1}
\starttext
\beginInvoice[bla=blub,
  blub=bla]
\startInvoice test \PRMblub \stopInvoice
\endInvoice
\beginInvoice
\startInvoice test \stopInvoice
\endInvoice
\stoptext
--8---cut here---end---8---

TIA,
--
