checking for module parameters

checking for module parameters

Hi,

is there a way to check whether an option was specified through \usemodule?
Couldn't find anything like that in core-fil.mkiv.

I'd imagined some branching as with the system macros:

······ Wishful thinking ·······················································

\doifmoduleparameter{modulename}{key}                      % in the module code
  {\somecommand[\moduleparameter{modulename}{key}]}

\usemodule                                                 % user code
  [modulename]
  [key=val]

····· /Wishful thinking ·······················································

Thanks for any suggestions,

Philipp

You can set a empty value for the kay in your module and check if the 
user has set a value with \usemodule:

\setupmodule[key=]

\doifsomething{\currentmoduleparameter{key}}{\setupsomething[key=\currentmoduleparameter{key}]}

For a better answer i have to know for what purpose you need this 
information.

Wolfgang

Hi Wolfgang,

you don't have to look any further, this is exactly what I was looking
for! (Note to self: maybe it is time to investigate the dozens of doif.*
tests a bit more thoroughly.) Thanks,

Philipp
