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

So

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

context --number=8 --time=full-time test.tex

...

\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

\starttext This is \doifdocumentargument{number}{\getdocumentargument{number}} it. This is \doifdocumentargument{time}{\getdocumentargument{time}} it. \stoptext Marco

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 -- Peter

Indeed.

...

Alternatives:

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

Or:

% context --arguments=number=8,time=full-time test.tex

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

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 On 10 Sep 2012, at 14:02, Sietse Brouwer wrote:

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.
