Hi list,
using this example from the wiki, the dbend symbol appears cropped on the left side on my machine (ConTeXt ver: 2021.12.10 11:41 LMTX fmt: 2021.12.14), but not on the ConTeXt live server? Any possible reasons?
\definefontsynonym [bends] [file:manfnt.afm]
\startsymbolset [Dangerous Bends]
\definesymbol [dbend] [\resolvedglyphdirect{bends}{n:char_7e}]
\definesymbol [lhdbend] [\resolvedglyphdirect{bends}{n:char_7f}]
\stopsymbolset
\setupsymbolset [Dangerous Bends]
\starttext
\symbol{dbend}\quad \symbol{lhdbend}
\stoptext
Thanks
Benjamin

Hi list,
I'm playing around with blocks and buffers again, realizing that I cannot use them inbetween a \start...\stop that I defined myself. Apparently, they work between \startsection...\stopsection and the like, so I was wondering how I should define or expand #2 in the MWE below to make TeX happily accept these useful features?
Thanks a lot
Benjamin

buffers are stored as-is so no catcode magic stored, contrary to macros
you can use \setbuffer but that doesn't solve the argument passing
however, you can nest buffers so you can make other \start\stop commands
buffers too and then do some at the start and (look for \defiebuffer)
but it quickly becomes messy i think

The lhdbend renders funny anyway. Maybe Taco is willing to have a look
at it. It might actually make sense to make an opentype font and get rid
of the afm/pfb here.

Thanks, Hans, for the answer, but I'm not sure if I get the point.
While this is possible in ConTeXt:
\startsection[title={My Title}]
\beginMyBlock
bla bla
\endMyBlock
\stopsection
The following won't work (end of file error):
\startMyCommand[optional={Maybe}]
\beginMyBlock
bla bla
\endMyBlock
\stopMyCommand
I had hoped for a simple command/modifier like \pleaseacceptblocks\def\startMyCommand[#1]#2\stopMyCommand to have #2 work in a similar way.
But maybe, as Wolfgang stated here (https://www.mail-archive.com/ntg-context@ntg.nl/msg73956.html), buffers and blocks can't be used in commands. (To add: Even when passed as arguments during compilation?)
Many Thanks again!
Benjamin

You can bet that WS is right.
You really have to go dirty tex for this kind of magic:
\defineblock[MyBlock]
\keepblocks[MyBlock]
\starttext
\tolerant\def\startMyCommand[#1]%
{\begingroup
\setcatcodetable\notcatcodes
\dostartMyCommand[#1]}
\let\stopMyCommand\relax
\normalexpanded{\def\noexpand\dostartMyCommand[#1]#2\expandtoken\notcatcodes92
stopMyCommand}%
{\endgroup
% whatever #1 does
\setbuffer[foo]#2\endbuffer
\typebuffer[foo]
\getbuffer[foo]}
or
\normalexpanded{\def\noexpand\dostartMyCommand[#1]#2\retokenized\notcatcodes
{\stopMyCommand}}%
{\endgroup
% whatever #1 does
\setbuffer[foo]#2\endbuffer
\typebuffer[foo]
\getbuffer[foo]}
\startMyCommand[optional={Maybe}]
\beginMyBlock
bla bla
\endMyBlock
\stopMyCommand
\stoptext
and then of course further nesting mess ...

Uff, this is indeed deep tex. Thanks a lot for the example, Hans! I still need to learn a lot.
After a walk and a bit of fresh air, I found another (much easier) way around my problem. This works since I don't need to deal with #2 in any special way:
\tolerant\def\startMyCommand[#1]%
{
\startallbeautifulcontextcommands
% whatever #1 does
}
\tolerant\def\stopMyCommand%
{
\stopallbeautifulcontextcommands
}
Then one can do in the main files:
\startMyCommand
\beginMyBuffer
bla bla
\endMyBuffer
\stopMycommand
