Hello,

After reading a bit in mtx-context.lua, I've found out how to use
--arguments:

test-file:

\starttext
Value of myVar: \ctxlua{tex.print(document.arguments["arguments=myVar"])}
\stoptext

cmd-line:

context --arguments=myVar=myValue test

But this syntax is very strange!

This would be much nicer:

Value of myVar: \getvariable{environment}{myVar}


Perhaps there is just a bug in the evaluation of environment.arguments?
That means, instead of using the first equal sign (=) for generating the
key/value pair, the last one is used.

Is this the right way to go: \systemparameter{file} ?

Cheers, Peter
