Re: [NTG-context] Struggling with startuseMPgraphic and string argument!
Hi ConTeXt users,
That's indeed magic and it works! Hans, thanks for your prompt answer!
But I would like to take this a step further, by introducing a macro
within the start/stopuseMPgraphic structure like so:
\startuseMPgraphic{name}{s::lbl}
def mymacro (text lb) =
pair a ; a := (3cm,3cm) ;label.top("String: " & str lb,a) ;
enddef ;
mymacro(\MPvariable{lbl}) ;
\stopuseMPgraphic
and this works too, but what if I introduce another text argument like:
\startuseMPgraphic{name}{s::lbl,s::label}
def mymacro (text lb,lbx) =
pair a ; a := (3cm,3cm) ;label.top("String: " & str lb & ", " & str
lbx,a) ;
enddef ;
mymacro(\MPvariable{lbl},\MPvariable{label}) ;
\stopuseMPgraphic
However this doesn't work! It gives the following error:
! Missing argument to mymacro.
Isn't that weird? But perhaps it has to do with me not understanding
argument passing properly within METAPOST macros!
Can someone please explain why this 2 argument example doesn't work?
(But maybe this isn't the proper list to ask questions like these. If
so, I'm sorry for bothering you!)
Regards,
Gerard

Thank you for this illustrative example, Wolfgang.
So, what \forgetparagraphfreezing does is to reverse the order that
lmtx currently imposes by default, right? In other words,
\forgetparagraphfreezing, recovers the default behaviour of MkIV.
So, I suspect that this will not change; if we want to apply
Lettrine to a paragraph, from now on we must wrap it up with
\forgetparagraphfreezing and \setparagraphfreezing.
Please correct me if I'm wrong.
LMTX removes some restrictions for settings which are applies to
paragraphs, e.g. the following example works now without problems
with LMTX while LuaTeX needs the \dontleavehmode at the begin of the
paragraph
\starttext
\placefigure[left]{none}{\framed[width=2cm,height=2cm]{}}
%\dontleavehmode
{\bf Tufte: }\input tufte
\stoptext
To avoid side effects from these changes LMTX freezes a few settings
at the begin of the paragraph. In some cases commands or settings
have to be adapted to these changes and the lettrine module is one of
them.
The changes itself to the commands have to be made in the modules
etc. itself and not in the documents, below is a minimal example how
the lettrine module has to be changed to get indentation for the
initial back.

BTW: ConTeXt already provides a command to place initials as part of
the core but it lacks a few features of the lettrine module.

Hi,
It seems that the Lettrine module is one of those affected:
https://tex.stackexchange.com/questions/562534/does-context-fail-in-the-lmtx-environment-with-the-lettrine-module?noredirect=1#comment1418902_562534
But, honestly, first, I don't know what means "/Of course it might
have other side effects once in lmtx we everywhere expect freezing
to be enabled./"
I suppose that, in order not to be a nuisance (and not to digress
into this real subject of interest), a short answer would be enough
to put me on track to investigate it.
On the other hand, I suppose the best practice, from what I have
just read, would be not to use \forgetparagraphfreezing globaly, but
\forgetparagraphfreezing and \setparagraphfreezing at the beginning
and end of the first paragraph respectively of each chapter. Would
this be the least harmful way? That is, wrapping it up to avoid this
provisional failure of the Lettrine with LMTX module, but at the
same time to avoid affecting that default freezing proposal in the
rest of the document, right?
By the way, and just out of curiosity, how does the recommended
provisional command work? Would it be something like this in the
preamble?:
\definingparagraphs
firstparagraph][n=1]
\setupparagraphs [firstparagraph][1][align={hanging}]
And then this arrangement in the \input files?:
\startfirstparagraph
\lettrine{B}{lah} blah, blah, blah...
\stopfirstparagraph
\blank [overlay] \strut
I know it's a dirty, inelegant solution, but I can't think of a
better one at the moment.
Below is a minimal example which doesn't rely on the module,
the problem is caused by the order of the \noindent and \parshape
command.
When a paragraph starts before the \parshape values are set
the arguments are ignored because the values are already frozen
at this moment, when you set the values before the paragraphs
starts ConTeXt applies them.
\starttext
\hsize 10cm
% lettrine module, \noindent before \parshape
\noindent
\parshape 3 1cm 9cm 1.5cm 8.5cm 0cm 10cm
\input weisman
\blank
% working order, \parshape before \noindent
\parshape 3 1cm 9cm 1.5cm 8.5cm 0cm 10cm
