What's (in) a module?

What's (in) a module?

[Thomas A.Schmitz]

Two maybe related questions:

1. What constitutes a module? I wrote a couple of definitions and put 
them in a file t-foo.tex. When I write "\input t-foo" in the preamble 
of my document, everything works fine (so the file is found by TeX). 
When I say \usemodule[t-foo] or \usemodule[foo], I get "system          
: no macros found in module foo" and, obviously, "undefined control 
sequence." So: is there any special form for a module? I'm very curious 
because I defined a set of similar macros in another module, and 
everything works fine.

2. Is it possible to use a certain encoding file, enco-bar.tex, for 
parts of a file only? Could one define a macro (in a module???) that 
would do something like \switchtoencoding[bar] and switch back to the 
file's default encoding afterwards?

Thanks to all, best

Thomas

did you run mktexlsr?

you're talking about font encodings?

\definetypeface [PalatinoA] [rm] [serif] [palatino] [default] [encoding=texnansi]

\definetypeface [PalatinoB] [rm] [serif] [palatino] [default] [encoding=ec]

works ok; typefaces live in their own namespace

if you're talking about input encoding, you can switch regimes whenever you want

It's a file in my $HOMETEXMF which doesn't have lsR files. I ran 
mktexlsr nevertheless, but to no avail. I really fail to understand...

Yes, I'm talking about font encodings. For the utf greek stuff, I 
defined a file enco-agr to provide the named glyphs, which I call by 
adding \useencoding[agr]. But I just realized that this will only add 
these named files, not overload the other names in the default 
encoding, so I guess that's a non-problem after all.

I guess Adam was in touch with you. unicode vectors and modules for 
adding support for utf extended Greek are approaching completion. Maybe 
we can think where to put the stuff (five fonts at least). Maybe a 
CTAN/Context directory would be a good thing.

Thanks

Thomas

weird; can you run with: \tracefilestrue

Ha! That did it! tracefiles showed that ConTeXt was expecting a file 
name with six or less characters after t-; my module was called 
t-utfgreek, so ConTeXt was looking for t-utfgre and couldn't find it. 
Renaming to t-utfgre.tex solved the problem. Is this restriction 
hard-coded into the core or could it be changed somewhere?

So what about that CTAN directory? Would be a good idea, right?

sure, but coordinate that with patrick so that it is referenced right from the wiki

Hi,


[module t-utfgre.tex]

What about a section "modules" on contextgarden.net that can serve as
a place for downloading third party modules as well as syncing with
CTAN?

Excellent suggestion, will get in touch with you off-list!
