Hello,
I've a little feature request:
It would be nice, to have a command line option like "--setvalue x=y" or
similar for the "context" command to define a variable for the job.
Modes are already very nice, but often I need just one value for
conditional compiling a document instead of many binary switches.
Perhaps the "context --arguments" option is what I'm looking for, but I
didn't find how to use it.
Another option would be, to make the name of the result-file
("context --result=...") available, for example as "\resultname".
Cheers, Peter

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

Does
context --arguments="myVar=myValue" test
work too ?

Yes, I'm using bash, so --arguments="myVar=myValue" is the same as
--arguments=myVar=myValue
That means, context does not see the quotes.
But I've also tried this: context --arguments=\"myVar=myValue\" test
Error:
MTXrun | unknown script 'context --arguments="myVar=myValue.lua' or 'mtx-context --arguments="myVar=myValue.lua'
Cheers, Peter

OK, in this way syntax looks less strange

It's not the syntax of the cmd-line that looks strange, it's the syntax how
to get the value of the variable:
\ctxlua{tex.print(document.arguments["arguments=myVar"])}
I'm quite sure, that this is not Hans' intention.
As I've written yesterday, I suppose, that the following syntax is wanted:
\getvariable{environment}{myVar} but this does not work...
Cheers, Peter

how does it look with:
local flag, value = argument:match("^%-+(.-)=(.-)$")
.+ -> .-

I've changed the line in mtxrun.lua and now it works fine, thanks Hans!
There is another occurrence of this line in luatools.lua (line 3426),
perhaps it should be changed there too?
Cheers, Peter
