Passing variables on invocation- and reading them in ConTEXt

Passing variables on invocation- and reading them in ConTEXt

[Ian Lawrence]

A feeble request from me, again.

I'd like to pass variables into context on invocation, just as you can do with setting modes

So

context --arguments="number=8", "time=full-time" --mode=trial test.tex

And have the values of the variables show up in the body of the text, so:
----
\starttext

Hello world

% This is \getvariables{arguments}{number} it. % this does not work - what do I need here to write out the next line?

This is 8.

% This is \getvariables{arguments}{time} it. % Nor does this - what do I need here to write out the next line?

This is full-time.

\stoptext
----


As ever, I've trawled the manuals and wiki and archive emails (which is where the construct --arguments="number=8" came from.)

Thanks in anticipation

Ian

\starttext

This is \doifdocumentargument{number}{\getdocumentargument{number}} it.

This is \doifdocumentargument{time}{\getdocumentargument{time}} it.

\stoptext

Then you have to be sure, that --number and --time will never be special
parameters for context.

Alternatives:

"--MarcoPatzerNumber=8 --MarcoPatzerTime=full-time"

Or:

% context --arguments=number=8,time=full-time test.tex
\starttext
This is \env{number}.
This is \env{time}.
\stoptext

Indeed.

This seems the better alternative, since that's what the option was
made for.

Thanks to all. After about 30 mins exploring, it all came together. 

I'll try to add something to the wiki....the link below is fine if you know it's there, and that this is what you want. But the search function ("arguments" and variants thereof did not find it for me).

The best match for what I was sure would be there, is \env{}. I still have no idea how it's (semantically) related to --arguments...unless its all Dutch...

Kind regards

Ian

Probably in part because the word 'argument' is also used for
arguments passed to ConTeXt commands, and not just for arguments
passed to the context script on compilation. I've created a "were you
looking for...?" page at [[Command-line arguments]] --- that seems to
me the most obvious search term, so that page is now the first result
for that search. If there are any other synonyms you used when
searching that, you think, should point at [[Command-line arguments]]:
redirects are obvious improvements.
