RFE: Better error messages for \usemodule

RFE: Better error messages for \usemodule

[Brooks Moses]

Just now, I was trying to figure out how to write a module that ConTeXt 
would load.  Should be simple, right?  I wrote a file called 
"t-mymodule.tex", put it in a directory next to a test file that had the 
line "\usemodule[mymodule]", and tried processing it.

After scratching my head over "no macros found in module mymodule", I 
decided to try replacing the line with "\input{t-mymodule}".

This produced the very cryptic result of a "I can't find the file 
't-mymodule'.  Please type another filename:" error.  However, simply using 
"t-mymodule" as a replacement filename worked fine.

Eventually, after much consternation, I tracked the problem down to the 
fact that ConTeXt truncates input file names to 8 letters.  Thus, my 
\usemodule command was looking for files called "t-mymodu" and so forth.

Given the amount of trouble that I had with figuring that out, I'd like to 
suggest the following enhancement: can the "no modules found in..." and "I 
can't find the file..." errors be adjusted so that they give the shortened 
file name that ConTeXt is actually looking for, rather than the long file 
name?

I would also tend to suggest that "no macros found in module..." is a 
fairly misleading error message anyway, since it seems to imply that the 
module file itself was found.  It is particularly unclear given that it 
_doesn't_ show up if the module file exists but contains no macros!

The \input with braces is latex-ese. The TeX primitive is
   \input t-mymodule
and that would have worked.

However, as of ConTeXt release 2005.05.25, the original \usemodule
would also have worked: the automatic filename truncation was removed
in that version.

Hi,

Sorry about this triplication, My smtp server was reacting
so slow that I believed it was non-functioning, but turned
out the mail came through anyway.

Ah, ok.  I hadn't realized those were different!

Good to know; it _did_ seem like something that really was likely to be 
more of an annoyance than a useful thing.

Thanks for the corrections.  :)

another problem with textbackground

[Martin Kolarík]

Hi all,

I need to create document where all text is colored (e.g. gray). So I used
textbackground, and it works. But if I add some floating table into the
document, the text in the table is not colored corectly.

Small attached example show this, all texts should be red. The second table
has for the errorneous cell set [color=red] too, and neither this works.

Example is only an example -- real situation comes from XML document, which
is a bit more complicated and the color problems are a bit more complicated
too -- colors in the table (color and framecolor too) firstly appear after
the first in-cell color change, before this color change table is not
colored. But this I did not suceed simplify to the example.

Now it seems like textbackground affects floats too (why not) but with some
difficulties. One could expect some "renewing" of the backgrounds in the
floating table (again why not :-), but this does not work fully too.

Thanks for any hints or corrections,

have a nice day,

Martin

There are a few file reading macros, for instance:

\readfile {yourfile.tex} {\message{OK}} {\message{BAD NEWS}}

supp-fil.tex shows a few (global loading, local loading, recursive 
loading, etc) ans in core-fil there are some macros to load files with 
knowledge of system paths and such

it was useful in the days that 8+3 filenames were the rule (msdos but 
also cdroms demanded it) and that the tex binaries were not able to 
handle truncated names well

looks funny and buggy to me; you can file a bug report on the temp wiki 
bug page

forget about background in your case, just use:

\setupcolors
  [state=start,
   textcolor=red]
