Hi all,

Currently I am using

\startuniqueMPgraphic{foo} ... if (\DbgFill=0) : fill whatever fi ... \stopuniqueMPgraphic

in my MP graphics. \DbgFill (0|1) is just a trigger, which prevents filling in case of visual debugging. Instead of always writing this 'long' form, it should be possible to use a self written mp-macro instead. But my naive approach

def dbg_fill (expr p) = if (\DbgFill=0) : fill p ; fi enddef ;

doesn't work. I get

...

...

DbgFill

! Unknown relation will be considered false.

How do I realize this trigger inside pure MP code and set it outside in TeX? The trigger should be global and can change during runtime. Any help is welcome.

can you make a test file?

I tried and my example code works at the beginning. After some changes things run wild (only possible in TeX ;) ). Not even the 'long' form worked any more.

So I went to contextlive and copied the simple test file. To my astonishment it didn't work either. But more important, the log file shows the same MetaPost error message I get, since ConTeXt swapped to ruby (preventing me from updating). Testfile and context live log (html) are attached. If someone can solve this problem I would be very glad.

Greetings, Peter

Hans

Adding a semicolon after the 'endgroup' command removes the error.

(I just looked at your pdf document).

You probably want 'useMPgraphic' instead of 'uniqueMPgraphic'.

You need a semicolon at the end of a statement. The <if> and <loop> constructs are not statements, they are preprocessed.

You get the 'extra tokens' error when Metapost sees something like

endgroup a:=1;

because it knows that 'endgroup' can only be a statement on its own.

I'm not sure what you mean. Using 'useMPgraphic' to load all kind of MP graphics?

You have to use \startuseMPgraphic and \useMPgraphic instead of \startuniqueMPgraphic, otherwise the output of both images will be identical.

The following code works here, but not at context live. What have I done now? ;)

Hi Taco (debugging grandmaster),

Hi Peter and "Author of Live.contextgarden.net",

:)

I have a real special ConTeXt installation (85MB in a ramdisk; eshell), so live.contextgarden.net is a good place to check code on a more 'normal' platform. Using context live I can simply see if it's my problem (most too often) or a general one.

Thanks again and also to Patrick for this really nice feature.

Greetings, Peter

Not something you did ;-)

Your first comment line is confusing the Live setup. This extremely minimal example fails as well:

% interface=en output=pdftex \starttext Hello \stoptext
