Well, this one took me a while to uncover (btw, one can trace these things 
by setting \protectionthreshold to zero)

The problem was introduced when adding support for french active : ; etc. 
The reset code was generated under an unprotected regime, so the patch goes 
into lang-spe.tex;

fonts fonts and fonts

[Hans Hagen]

Hi all, 

Fonts is still one of the more complicated areas in tex. I have written a
perl script that can do some of the tasks needed to install a 'commercial'
font under context. I'm also working on some math fonts (like micropress
informal which is a nice one and y&y mathtime that can be used with many
fonts).

There are several issues that need to be taken care of: 

- copying fonts the right location in the texmf-local tree
- generating a map file for pdftex 
- generating font synonyms

Now, i'm thinking of setting up a font tfm/vf/map repository but first i
want to knwo if there is any need for that. 

An important issue is the encoding and naming. I know that there are all
those predefined kb font names, but i never work that way: i just use the
original names and one encoding. So, we need to make choices as well as
provide methods, auto map file inclusion etc. It's not that hard actually
but i can only do this if we agree upon it. I want to get rid of the tex
font mess -)

How many of you use fonts other that cmr and what fonts? In what encodings?
In what combinations?  

Hans

I do, I use a special set of the Times font that Taco configured for me. I
have no idea what encodings and combinations -- I looked into it but
concluded that it's all way above my head.

If it were easier I would probably sooner contemplate buying a new font
family. As it is, it would mean spending money on PFB files and being
completely lost with them, unless I could find a guru like Taco to do all
the installation work ;=}}

Groet!

Are you using fontinst for this? This should imho be the best way to do
it, because you can also use the font for tex/latex.

tetex keeps all font-related files in subdirs foundry/fontname, e.g.
fonts/tfm/adobe/minion.

> - generating a map file for pdftex 

This should be easy. But pdftex needs to know about the map file.  For
tetex you have to edit the script updmap and place the name of the new
map file in a variable. After that you need to call updmap, which will
create a new map file for dvips and pdftex.

> - generating font synonyms

The user should tell the script if it's a serif, sansserif or whatever.

A repository for what?

Imho it's better to stay with fontinst. But this certainly needs
an easy-to-use frontend. If you tell the user, after fontinst has
completed, that he can now use Minion by \setupbodyfont [minion], then
he won't see anything of the "tex font mess". So the user should use the
real name of the font, but the software the kb names.

> How many of you use fonts other that cmr and what fonts? In what encodings?

I have used the standard pdf fonts, Lucidabright, Utopia, Charter and
the Microsoft Core Fonts. All in texnansi encoding, because I still
don't understand how this encoding stuff works... :-(  But I never
had problems with this. Except that some symbols are taken from
the Computer Modern Math fonts.

Hope this helps.

fontinst is a confusing affair. While it is fairly easy to install
a simple text font with it, it is very hard to do something complicated.
People keep telling me that it's possible, but it doesnt make a lot
of sense to me. 

Also, I don't understand why it was coded in TeX (don't tell me it is
for ease of use ... it's not easy to use ... and it's not helpful for 
portability ... fontinst doesn't even do any of the non-portable stuff). 

In short: I don't like fontinst, nor will I ever. But it does make 
sense to create an 8t/7t encoded tfm along with the texnansi one for 
context.

In general, this is the easy part (at least for all TDS-conforming
distributions).

updmap is a hack. I'm sure Thomas would be happy to replace it
with something cleaner.

For metric files, basically. Right?

Y&Y still have the tfm files for the full Adobe library on-line, which 
is basically the same idea hans is going for. Have a look at:

I believe that if you do all of the hard work yourself anyway, that
it is probably a better idea to replace fontinst alltogether. (But,
as I said earlier, keeping the functionality intact). 

Technically: it is easy to replace 8r (the so-called Adobe Raw encoding)
with 8y (texnansi) as the base encoding on top of which you can build
the 8-bit latex virtual font version.

I lost track, really. :-)

texnansi is generally the easiest encoding to install, so most of the
simple fonts I used had that encoding, and most of the hard ones had
'do-it-yourself' encodings. (trying to fit e.g. TimesExpert into the 
'text companion' encoding is just too much work for me).

I do use fontinst, because I don't have anything more reasonable to deal
with things like composed glyphs, letterspacing, kerning and the likes.
Don't tell me that afm2tfm can do that job.

indeed, with the accompanying map files, i now generate something 

texnansi-adobe-myriad.map 

as well as a tex test file which also shows how to include them (using
their internal names, which for some reason are always inconsistent:
blabla-bold-italic vs blablabold-italic vs blabla-bolditalic vs blabla-bi
or whatever).

well, if *you* lost it, then who kept track

A thought: why not use unicode mapping? The regimes can map onto it and
internally we can then stick to <font><char> pairs. We only need to create
series of virtual files i suppose? I don;t know what the consequence for
patterns is, but it would solves the mix ten languages that don't map onto
one font instance problem

Walter Schmidt told me, he is detecting more and more errors in fontinst,
 the more he looks into it... (esp. for small caps and other expert fonts)

I have the Lucida Bright Expert collection on order.  In the poetry
chapbook I'm currently working on, I'm thinking of using Lucida Bright
in the body and Ludica Casual or Handwriting for headings.

I've done two other poetry chapbooks with LaTeX, one in Palatino, and
the other in the Pandora metafont, which I liked quite alot.

I'm looking for recomendations for fonts that are a little decorative
but still easy to read for typesetting poems.

I do like the "Bradley Hand" but haven't used it yet for longer texts 
myself.  But the Adobe Illustrator handbook shows some longer texts with it 
and there it looks very good.

If you succeed in creating an easy way to install commercial fonts,
this tool will likely become very popular.

I used postscript Courier bold once.  (Mostly I stick to cmr, partly
because there's been no tool like the one you're making.)

I do love fonts.  And I use many different ones (not in the same document 
thought!)  For the last project (a journal that I promised to make a report 
about the work) I managed to implement a family of TTF fonts (Glasgow 
Serial) from the demo collection:
  http://www.freefont.de/de/megastar.htm
and a headline font (Batmos) from
  http://buddha.graphix.dk/

There are lots of problems with the existing tools.  I hope to prepare a 
report on that font challenge the next days ...

Re: fonts fonts and fonts

Another font hint:
There are some new font packages (metrics, install instructions etc, 
no pfb) for LaTeX by Walter Schmidt on his homepage:
<http://home.vr-web.de/was/fonts>

Perhaps someone could adapt them for ConTeXt?

ah, in context \protect does something like \makeatletter in latex (only in 
context ! and ? are also used for protection purposes)

[afaik in latex there is a \protect that has to do with preventing 
expansion in toc entries; context does not need this since normally toc 
entries are not expand them at all; in context expansion only can be 
problematic in tests, which is why some commands are defined with 
\unexpanded\def, which actually in etex is equivalent to \protected  \def, 
which clashes with my own \protected, and (lucky me) \unexpanded is also an 
etex primitive with a complete different meaning; lesson: don't confuse 
\protect with latex \protect and don't mix up \unexpanded with etex's 
\protected]

anyhow, not something for users to bother about

Environments, Projects, Products, Components

[Giuseppe Bilotta]

Hello,

I'm getting the first attempts to structured ConTeXt, and I needed
some clarifications.

As I see it, it goes like this:

environments are more or less the equivalent of LaTeX2e classes.

Projects are collection of material (say, Calculus books)

Products are the single books (say, Calculus, Advanced Calculus)

Components are the single chapters of the various books.

If this is correct, I'd like to know if it is possible to
structure components in such a way that they can be recycled. I
mean:

imagine that I'm writing two books, BookA and BookB, and imagine
that both books have a chapter in common, say ChapFoo.

If I was thinking of the single books, I would write:

(booka.tex)
\startproduct booka

\component chapbar
\component chapfoo

\stopproduct

(chapfoo.tex)
\startcomponent chapfoo

\product booka

\starttext
the text for this chapter
\stopttext

\stopcomponent

But now, what if I say

(bookb.text)
\startproduct bookb

\component chapquuz
\component chapfoo

\stopproduct

?
Shouldn't I change chapfoo.tex so that it says \product bookb?

Any clarification appreciated.

Correct.

Just delete the \product line alltogether, it is optional. :-)

Or you can do it like this:

chapfoo.tex:

...
\product booka
\input chapfoo-contents
...

chapbar.tex:

....
\product bookb
\input chapfoo-contents
...

I see. Hadn't thought of that ... which do you think is the better
idea? taking \product off is space-saving (only one file per
chapter, instead of two wrappers plus the file), but somehow seems
less structuring ... maybe I'd better keep \product in until I
need to use the same file somewhere else ...

What happens if product booka meets a component that says \product
bookb?

If I understand correctly, nothing. I *think* \product is in there 
to allow partial compile of  the component. But I not sure and
I've never used this stuff so I am just doing a guess here.

Is there a complete example anywhere that uses partial compilation? I
couldn't get it working before and just assumed that I'd misunderstood
what it was for.

Attached is a set of files. You should be able to run the components 
(onderdeel) and products separately.

the examples are dutch so you need to generate a dutch format or translate 
them to english first

omgeving => environment
onderdeel => component

[leerdoel => learning objective]

there are also locale env's that can be loaded per product so in that case
you may waqnt the directive so that context can backtract the doc tree.
some day this will be more extensive [split doc processing and auto cross
doc/toc refs and so]

Horizontal centering \startlines...\stoplines

[Steve Lumos]

Hi.

I've just recently started using ConTeXt for the purpose of
typesetting a poetry chapbook (small, usually self published,
typically saddle stitch bound).  I can't begin to tell you how much I
love how easy the layout becomes with ConTeXt.

What I'm wondering is whether there is an automatic way in ConTeXt to
horizontally center a poem (or any fairly long block of short-line,
ragged-right text) on the page.  For example I would like to do
something like:

\definehead[Poem][subject]
\setuphead[Poem][alternative=middle,textcommand=\ss]

\setupindenting[big]
\setuplines[indenting=even]

\starttext

\Poem{deMorgan}
\startlines
Great fleas have little fleas
    upon their backs to bite 'em
And little fleas have lesser fleas,
    and so ad infinitum,

And the great fleas themselves,
    in turn, have greater fleas to go on,
While these again have greater still,
    and greater still, and so on.
\stoplines

\stoptext

except wrapping the \startlines...\stoplines in some magic so that the
poem is beneath the title and without having a human to measure with
width of the widest line.  This is especially important for setting
poems in two columns because in that case the title looks strange no
matter where you put it.

With LaTeX in the past, I have either lived with everything on the
left which makes the title look funny, or resorted to putting each
poem in a minipage of a width found by trial and error.

\stopFancyPoem

\stoptext

Of course this is a rather minimal implementation.

Re: Horizontal centering \startlines...\stoplines / poems

[Steve Lumos]

This centers the title on the poem, but what I was hoping to do
was center the entire poem horizontally on the page.  This definitely
gives me a way to get started though.

Changing width like this moves the margin away from the edge of the
page.  I'm doubltess about to show how much of a beginner I am, but
this is what I did:

\def\startCenterBlock%
  {\beginofshapebox}

\def\stopCenterBlock%
  {\endofshapebox
   \dimen1=0pt
   \reshapebox
     {\setbox\scratchbox=\hbox{\unhcopy\shapebox}%
      \ifdim\wd\scratchbox>\dimen1 \global\dimen1=\wd\scratchbox \fi
     \unhbox\shapebox}
  \dimen2=\hsize
  \advance\dimen2 by-\dimen1
  \divide\dimen2 by 2
  \moveright\dimen2\box\newshapebox
  \flushshapebox}

I'm not sure whether it is considered bad to reference \newshapebox,
but I couldn't figure out another way.  This seems to work as long as
the poem is shorter than a page.  I'm still playing with settings, but
here's what I'm using now if it makes any difference:

\definepapersize[booklet][width=5.5in,height=8.5in]
\setuppapersize[booklet][letter,landscape]
\setuplayout
  [topspace=0.1in,
   backspace=0.25in,
   header=0.25in,
   footer=0pt,
   leftmargin=0pt,
   leftmargindistance=0pt,
   rightmargin=0.4in,
   rightmargindistance=0.1in,
   height=fit,
   width=fit]

\setuppagenumbering
  [alternative=doublesided,
   location={header,inmargin},
   command=\InverseBox]
\setuparranging[2UP,rotated]

In your case teh box is now empty so the flush cannot handle odd cases, 

\setbox\newshapebox\normalvbox{\moveright\dimen2\box\newshapebox}%

may be a better way, or simply leave out the \flush...

Setting up footnotes...

[Joop Susan]

Hallo,

I would like to see my footnote numbers as a superscript number followed 
by a ')'. I need my footnote references to be a bit more visible and 
slightly bigger targets in interactive documents. (A CMSS superscript '1' 
just looks lost ;-))

I have tried:

\def\Myfooternumber#1%
    {\high{#1)}}

\setupfootnotes
    [numbercommand=\Myfooternumber]

This only changes the presentation of the footnote number at the bottom of 
the page, but not the reference in text.

Can anybody tell me which command changes the reference as well?

Joop

This is rather hard coded, so I have to look into it.

I'm only working on one project, so for the time being I can live with 
hacking the source to get it right for this project.

I'm a TEX amateur. I couldn't figure out all the \v!, \@@vnwijze, etc. So 
my solution is crude (but effective!).

I hacked \dofootnote in core-not.tex as follows:

\def\FootnoteNumberCommand#1% This defaults to just the number
  {#1}

\def\dofootnote#1%
  {\iffootnotesenabled
     \doglobal\increment\internalfootreference
     \doifelse{\@@vnwijze}{\v!per\v!pagina}
       {\settrue\pagewisefootnotes}
       {\setfalse\pagewisefootnotes}%
     \doifelse{#1}{-}
       {\let\footnotenumber=\empty}
       {\ifconditional\pagewisefootnotes
          \doifreferencefoundelse{\s!fnt:t:\internalfootreference}
            {\ifnum\currentrealreference>\lastfootnotepage\relax
               \global\let\lastfootnotepage\currentrealreference
               \resetnummer[\v!voetnoot]%
             \fi}
            {}%
        \fi
        \verhoognummer[\v!voetnoot]%
        \maakhetnummer[\v!voetnoot]%
        \def\Myfootnotenumber{\FootnoteNumberCommand{\hetnummer}}
        \rawtextreference{\s!fnt}{#1}{\Myfootnotenumber}%
        \let\footnotenumber=\Myfootnotenumber}%
     \expandafter\dostartfootnote
   \else
     \expandafter\gobbleoneargument
   \fi}

In my document source files I can override FootnoteNumberCommand:

\def\FootnoteNumberCommand#1%
  {[#1]}

or

\def\FootnoteNumberCommand#1%
  {\inframed[offset=0.2ex,strut=no,width=fit,height=fit]{#1}}

It looks like \setupfootnotes needs another option that accepts a 
command...

No doubt you will be able to fix this in a proper way. Unfortunately I 
lack the skills...

I'm using tetex-1.0.7 with updated pdftex binaries (Version 
3.14159-14f-released-20000525-2.1) and an updated context tree (ver: 
2000.5.31).

You can add such a fix in cont-loc.tex which is loaded at runtime. That way
you can keep track of such hacks. 

BTW, the \tx is doing the hardcoded font switch in the footnote number.
Make that \bfx and you get bold ones.
