XeTeX questions

XeTeX questions

[Thomas A. Schmitz]

I'm trying (once again) to find out if learning something about XeTeX  
is worth the trouble. So far, I haven't seen any compelling reason,  
but I'd like to experiment a bit more. Here are two questions I have  
run into:

1. in the wiki pages "Talk:XeTeX," there's this anonymous piece of  
wisdom:
Referencing fonts by filenames

(just a note from the XeTeX mailing list as a reminder for later)

in texmf.cnf:

OPENTYPEFONTS = .;$TEXMF/fonts/opentype//;c:/Resources/Fonts//
Then

\setromanfont{[KalligraphiaLTStd.otf]}

Is this possible or usable in ConTeXt? I have lots of OpenType fonts  
in ~/texmf/fonts/opentype, but not installed as system fonts, and  
would  like to see whether they can just be used with XeTeX as with  
vanilla pdftex. texmf.cnf is set up accordingly, but so far, I  
haven't had any success.

2. When generating the formats, texexec complained about "unknow  
control sequence" because of lines 25 and 26 in syst-xtx.tex

\setcclcuc 201C 201C 201C
\setcclcuc 201D 201D 201D

I had to comment out these lines to generate the formats (this is  
with a texlive2007 snapshot of last week and the latest ConTeXt). Is  
this a known bug?

All best

In the latest context, this is a known problem. But the TeXlive
should be ok, so ypou have me a bit worried. Are you sure it was
the latest snapshot and it did not accidentally read one of the
non-tl files?

Uhm, maybe I wasn't quite clear: the entire TeX foundation is the  
current texlive head; I last sync'd on Jan 17. ConTeXt version is  
2007.01.18. A look at the log doesn't reveal anything unusual, here's  
the beginning and end of the log file:

Perhaps I forgot to log in when I've put that note to the wiki ;)

I requested that feature in XeTeX and yet: it's now implemented in
LaTeX, but not in ConTeXt. (When Adam became a father, sad times have
started for fonts in ConTeXt ;)

Hmmm ... you can use OpenType fonts in XeTeX in a plain-TeX-way like that:
\font\a="[KalligraphiaLTStd]" \a

But there's no high level interface for it yet. The relevant pieces
are in font-ini.tex:

%D For \XETEX\ we need to support a bit more:
%D
%D \starttyping
%D \definedfont[{cmr10}  at 40pt] test
%D \definedfont['cmss10' at 40pt] test
%D \definedfont["cmtt10" at 40pt] test
%D
%D \definedfont[{cmr10}  at 40pt] test
%D \definedfont['cmss10' at 40pt] test
%D \definedfont["cmtt10" at 40pt] test
%D
%D \definedfont["Gentium" at 40pt] test
%D \stoptyping

But one would also need \definedfont["[KalligraphiaLTStd]" at 40pt] or
a similar command (double brackets look ugly anyway) to pass the same
font name to XeTeX. If some TeXacker knows how to fix the low level
macros responsible for it ... ;)
I was silently hoping that once that Taco or Hans implement the same
feature in luatex, one of them would also fix the corresponding macros
for XeTeX. My knowledge doesn't suffice for it.

Change it to \setcclcucx or wait until Hans uploads a new version ;)

Ah ok. 2007.01.18 is broken indeed, but that is not the 'core' one on
TeXLive, that has 2007.01.12 15:56, and I am not going to update that
one any more.

Have you tried

   \definedfont[{"[KalligraphiaLTStd]" at 40pt}]

yet? Sorry, I have simply no time to toy around with XeTeX myself.

Oh that's where Adam has been hanging out lately! I was wondering

OK, I see; thanks for clearing that up, Mojca. Since I have no  
pressing need, I guess I will leave it at that.

But since I know that you've done a lot of work on XeTeX in ConTeXt,  
I'd really like to know: what exactly can XeTeX do that would make me  
want to take a more thorough look at it? After a sometimes painful  
learning curve, I find it nowadays relatively easy to make my  
opentype fonts work in ConTeXt. I assume that once the integration of  
opentype in luatex is finished, this will be even more  
straightforward, giving us access to many opentype features. I'm just  
wondering if it makes sense to spend more time here or if the XeTeX  
project will be eaten by its own success, as it were, as most of what  
it offers becomes integrated into lua/metatex. If you can spare two  
minutes, I'd be very grateful to have your thoughts on this.

Yes sorry, I saw your post on context-devel only after posting my  
question.

Thanks a lot!

Re: XeTeX questions

[Thomas A. Schmitz]

Well don't laugh: I tried your suggestion and found that this works:

\definedfont[{{[GFSDidot] at 20pt}}]

the two pairs of braces seem to be needed. Not a pretty sight, though...

Hmmm ... not until you suggested it ;)

Thanks a lot! (Why on earth haven't I thought about that before?)

That basically means that now I can finally try to add a bunch of
(although ugly, but at least working) definitions to get the OpenType
version of LM version used by default when launching XeTeX. (I tried
it already and it seems to work OK, but it has to be completed and
cleaned a bit first.)

Now I only have to figure out what is happening with map files. There
were some complaints a few days ago (and at that time it worked OK on
my computer). Now, when I tried to use OpenType LM, it complains about
wrong (dvips) map files (my TeXLive installation is not the most
recent one). But I noticed that there were some dvipdfm map files for
lm added to TeXLive recently, so I hope that the problem will go away.

Did you read my long and confusing rant about map files? (If not, don't
worry about it). As of this morning, there should be pdftex as well as
dvipdfm map files for all of the latest tex-gyre and latin modern font
releases included on TeXLive.

In summer I almost lost my nerves when I had to make a presentation
with Lithuanian, Turkish, Romanian, ... Vietnamese names (and had only
one night to make it ready). One letter was missing in Unicode vectors
for pdfTeX, [st]cedilla/commaaccent was problematic anyway (iwona and
lm use different letters on the same slot), for Vietnamese I needed to
redefine the font (\ifcountryisvietnamthen ... and font switching
macros seemed to have little bugs, so some specific combinations of
commands failed for basically no reason). It was a headache. (I needed
external figures and I didn't know that using them was possible in
XeTeX.)

Two other reasons why I'm sometimes using XeTeX is the ability to use
any font and the ability to use any glyph without too much troubles
(all that might be possible in pdfTeX, but even now that I potentially
know how to do that, I stil find it too cumbersome - too much work
just for the sake of being able to use a single font for a title
somewhere on a poster - too much overhelm).

Well ... another reason might be "just because it's fun to play a bit" ;)

You can do a lot more than that (typeset the most obscure scripts in
the world), but if you don't ask for it, you probably don't need it
either.

Well ... I didn't manage to get over this (buggy windows tools -
neither lcdftypetools nor texfont worked properly) and aferwards I
didn't want to take time for it (I know that it's history, not the
future, so it makes no sense to loose time with it). But if you don't
have problems like the one described above, if you don't need "fancy
apple fonts" and if the desired fonts work OK for you, there's
probably no reason to switch.

And when talking about "should I switch to XeTeX":
The nice thing about ConTeXt is that you usually shouldn't notice the
difference at any point of the document except for possibly sligthly
different line with font definitions.

It depends on what you consider "spend more time". If I'm not counting
the time reading the XeTeX mailing list, writing feature requests or
doing minor fixes in code or on the wiki from time to time, there's
basically no additional time involved. It simply works out of the box.

Perhaps the two will integrate again once in the future ... ? (just as
Aleph & eTeX & pdfTeX have been integrated now)

It's pointless to worry about that. XeTeX has features which won't be
supported in luatex (AAT, but there are surely more of them) and some
users need those.

I did. But at that time it worked fine here ;)

Yes, I've noticed. I hope that it will work without any problems.

why are the nested [] needed

(btw, later this year i may come up with an extension to the font 
definition macros more suitable for open type; in that case we can 
convert to xetex syntax behind the screens)

fonts is more than definitions; esp a the level of supporting features and runtime manipulating fonts, xetex and luatex will undoubtely differ; also, xetex uses external font libraries, while luatex does things internaly and under user/macro conytrol (with defaults); due to the nature of fonts, both systems will share characteristics ... the future will learn; from context's point of view ... we will provide a high level interface so users will probably not notice the gory details

because it may work or not, depending on if the argument is passed on to 
submacros using [] as delimiter; taco knows such dirty details -)

are these [] really needed?

[GFSDidot]


is not a prettu sight anyway; does it fail when you don;t use those []'s?

It would be nicer if XeTeX would support TeX-style braces as well.
This is much less bizarre:

   \definedfont[{GFSDidot} at 20pt]

Yes, it breaks without the [].

Just came back from a day of excruciatingly boring meetings...

OK, I see where XeTeX has its strong points. And I can certainly  
agree: if you want unusual glyphs that are not part of a more-or-less  
standard encoding, that can be a PITA.

Yes, I was just wondering how much time I should spend on ``playing a  
bit.''

Well, that depends on your needs: the only ``exotic'' script that I  
use on a regular basis is polytonic Greek, and this works indeed out  
of the box (very impressive), but in my quick tests, failed to work  
as soon as I added the mapping=tex-text command to the font. But your  
post has been immensely helpful, Mojca. Thanks for your time, I  
really see where XeTeX is useful, but I also see that it probably  
won't do a lot for me.

That would be the best of all worlds... Just give us some Mk IV files  
to play with soonish...
