reset \use[sub]path

reset \use[sub]path

[Pawel Jackowski na Onet]

Hi all!

Lets consider the following situation. There are 3 catalogs; ./lofo1,
./lofo2, ./lofo3, each of them contains files 'aqq.xml' and 'cow.png' for
example. Filenames are the same, but they may have different content. I need
to include all these files into one PDF document WITHOUT giving absolute
paths in TeX code. I tried something like

\usepath[lofo1]
    \processXMLfilegrouped{aqq.xml}
\usepath[lofo2]
    \processXMLfilegrouped{aqq.xml}
\usepath[lofo3]
    \processXMLfilegrouped{aqq.xml}

but in this example the same file (./lofo1/aqq.xml) will be processed 3
times and that is not what I need. Actually the situation is even more
complicated; I have quite big XML tree with hunderts of files and images,
with dozens of catalogs. I wrote a perl script which change current
directory for each process and run texexec in changed one. And it works OK
since I want to have separate PDF document from each `lofo?' catalog. But
how to make one PDF document in such situation using \use[sub]path texnique?

In other words, how to reset settings from \usepath and \usesubpath
commands? And how to do the same for externalfigures?


Thanks in advance, Pawe/l

Thanks a lot but I still can't get it. After inspecting core-job.tex file
and tried
'reset' option. Also without expected results. So what is
wrong in the following code?

\starttext
\usesubpath[lofo1]
    \processXMLfilegrouped{aqq.xml}
\usesubpath[reset]
\usesubpath[lofo2]
    \processXMLfilegrouped{aqq.xml}
\usesubpath[reset]
\write16{\allinputpaths}
\stoptext

In this example \allinputpaths comma-list written to log looks like this:

lofo1,lofo1/reset,lofo1/lofo2,lofo1/reset/lofo2,lofo1/reset/reset,lofo1/lofo
2/reset,lofo1/reset/lofo2/reset

So 'reset' is treated as a directory name. Why? What am I doing wrong?

indeed reset only works for usepath

(has to do with the fact that any \usesubpath triggers extension of the 
path list)

I did so. I've noticed that 'reset' option works for \usepath only but I
still get the solution. Please consider the following example (attached). We
have './lofo1' and './lofo2' directories, each contains 'x.xml' file (the
same filename but different content). ConTeXt code is as following:

\starttext
 \usepath[lofo1]
 \processXMLfilegrouped{x.xml}

 \usepath[reset]

 \usepath[lofo2]
 \processXMLfilegrouped{x.xml}
\stoptext

In this case 'reset' option works probably OK, since \allinputpaths variable
IS redefined to \empty (lines 99 to 104 of core-job.tex). So I expect that
the first processed XML file should be './lofo1/x.xml' and the second --
'./lofo2/x.xml'. But './lofo1/x.xml' file is processed twice instead. What
construction should I use to process two or more XML files, which have the
same name but different localization? I'm aware that my problem is not
common but...

Thanks for Your help, Pawe/l

OK, I had a close look at it and digged into deeper mechanisms of
path handling in ConTeXt.

ConTeXt stores the exact location of a file just by the filename.
Once you read x.xml, ConTeXt remembers where it is. You get a hint
when saying \tracefilestrue in your tex source. Next time you read
x.xml, ConTeXt looks into its internal macros (fn..x.xml in this
case) and reads the full path. And this is lofo1 in your case.


I don't have a solution for you. Sorry.

Thanks anyway. No solution at this point is also some kinf of hint -)

page backgrounds

[Thomas A.Schmitz]

These are my first forays into the unknown territories of Metapost. The 
following code is copied verbatim from the matafun-manual:

\startuniqueMPgraphic{copyright}
picture p ; p := btex COPYRIGHT etex rotated 90 ;
setbounds p to boundingbox p enlarged 1pt ;
draw p withcolor .8white ;
currentpicture := currentpicture
xysized (\overlaywidth,\overlayheight) ;
\stopuniqueMPgraphic
\defineoverlay[copyright][\uniqueMPgraphic{copyright}]

\setupbackgrounds[text][rightmargin][background=copyright]

But I don't see anything. The log shows that metapost calculated a 
background, but I don't see anything. What am I doing wrong?

Re: page backgrounds

[Thomas A.Schmitz]

Let me provide an answer myself: the btex ... etex doesn't seem to 
work. This code:

\startuseMPgraphic{draft}
draw "DRAFT" infont "phvb" scaled 9 rotated 57 withcolor .85white ;
currentpicture := currentpicture ysized (\overlayheight-3cm) ;
\stopuseMPgraphic
\defineoverlay[draft][\uniqueMPgraphic{draft}]
\setupbackgrounds[page][background=draft]

will do what I want: provide a "watermark" for my document (or, as Hans 
writes, an "annoying text"). However, when I try the same with

draw btex draft etex

I don't get any output. Could you please verify if this is the case in 
your version of ConTeXt as well? Here's what I have (it's a vanilla 
teTeX implementation):

ConTeXt  ver: 2003.9.19  fmt: 2003.9.30  int: english  mes: english

MetaPost (Web2C 7.5.2) 0.641

Thanks, Patrick. \protectbufferstrue is uncommented (I guess that's the 
default, isn't it?). Does the btex...etex work on your box? Could 
anyone running Mac OS X (10.2 for the time being) verify if it works on 
their systems?

Hi Thomas,

I use Mac OS X (10.3 since today... but the following is independent 
of whether you use 10.2 or 10.3) together with TeXShop and Gerben 
Wierda's distribution of TeX.

The first example you sent, that is:

%% first example
\startuniqueMPgraphic{copyright}
picture p ; p := btex COPYRIGHT etex rotated 90 ;
setbounds p to boundingbox p enlarged 1pt ;
draw p withcolor .8white ;
currentpicture := currentpicture
xysized (\overlaywidth,\overlayheight) ;
\stopuniqueMPgraphic
\defineoverlay[copyright][\uniqueMPgraphic{copyright}]

\setupbackgrounds[text][rightmargin][background=copyright]

\starttext
\input knuth.tex
\stoptext
%% end first example

does not produce what is expected. The second example you sent, that is:

%% second example
\startuseMPgraphic{draft}
draw "draft" infont "phvb" scaled 9 rotated 65 withcolor .95white ;
currentpicture := currentpicture ysized (\overlayheight-3cm) ;
\stopuseMPgraphic
\defineoverlay[draft][\uniqueMPgraphic{draft}]
\setupbackgrounds[page][background=draft]


\starttext
\input knuth.tex
\stoptext
%% end second example

does produce the watermark "draft". The third example

%% third example

\startuseMPgraphic{brouillon}
draw btex brouillon etex ;
% draw "brouillon" infont "phvb" scaled 6 rotated 70 withcolor .95white ;
currentpicture := currentpicture ysized (\overlayheight-3cm) ;
\stopuseMPgraphic
\defineoverlay[brouillon][\uniqueMPgraphic{brouillon}]
\setupbackgrounds[page][background=brouillon]


\starttext
\input knuth.tex
\stoptext
%% end third example

does not produce what is expected.

I should say that I am not enough self-confidence to change the file 
cont-sys.tex as suggested by Patrick...

Best regards: OK

what did you expect?

this command scales (vertically) the brouillon to \overlayheight -3
cm. This is very large

> \stopuseMPgraphic
> \defineoverlay[brouillon][\uniqueMPgraphic{brouillon}]
> \setupbackgrounds[page][background=brouillon]

and this one centers your graphic (the large brouillon) on the page.

If you get some results from btex...etex, you don't have to.

It should print "COPYRIGHT" in the right margin. It works fine here.

Hello,

Right, I just checked. It was a common error in the past.

Yes, it does work here on OS X (Jaguar). I tried your example from
yesterday (slightly patched, though because there was no \starttext...)


Please post your complete logfile.

After verifying configuration on my machines, it works.
The TeXLive2003 on MacOSX install (main computer) worked fine, without
anything extra.
I have a gwTeX install on a second computer, and it took a bit of work to
get it going:
enabled \write18 by changing shell_escape to 't' in texmf.cnf
Copied user/cont-sys.rme to user/cont-sys.tex.
Did a 'sudo texhash' to be sure changes are made.
Edited cont-sys.tex and uncommented the following lines:
\runMPgraphicstrue
\runMPTEXgraphicstrue
\useMETAFUNformattrue % make sure you have a format!

In short, I followed the suggestions in minstall.pdf!

After all that, I was able to run both the "copyright" and "draft"
examples without any problem.

The down-side is that it takes a bit of confidence at the command line to
find all these files. I have to wonder if it would help to ship and
configure gwTeX/ConTeXt with better defaults for the Mac...

Otared, I would suggest making the changes recommended in pages 8-9...
they unlock a lot of functionality that seems to be "hidden" in ConTeXt!

You'll enjoy your journey once you get MP working.

Your complete log might be interesting. Did you enable the write18
feature in texmf.cnf (not necessary, but nice since it lets tex
generate the MP graphics on the fly)? Did you put any text between
\starttext and \stoptext? Do you have \protectbufferstrue in
cont-sys.tex?
