Wrap a url

Wrap a url

[David Arnold]

All,

I have:

\setupurl
  [style=bold]

\useURL[craig][http://online.redwoods.cc.ca.us/instruct/darnold/CalcProj/Fal
l98/CraigA/project3.htm]

\from[craig]

But it runs off my slide before wrapping. I'd like to break this up so it
is on two lines and centered. Any suggestions?

Re: Wrap a url

[Willi Egger]

there is \hyphenatedurl{http://www....}

May be this is what you are looking for.

Re: Wrap a url

[David Arnold]

Willi et al,

How do you use \hyphenatedurl? I tried:

\setupurl
  [style=bold]

\useURL[craig][\hyphenatedurl{http://online.redwoods.cc.ca.us/instruct/darno
ld/CalcProj/Fall98/CraigA/project3.htm}]

\from[craig]

But this gave me:

ERROR: Improper alphabetic constant.

--- TeX said ---
<to be read again> 
                   \hyphenatedurl 
\scanurl ...d #1\relax #1\else \ifnum \catcode `#1

Re: Wrap a url

[David Arnold]

Hans et al,

Thanks. This worked.

I am seeing here and there that the syntax for \useURL is:

\useURL[][][][]

The first [] is to hold a symbolic name such as "craig" that can be
referred to latter, as in \from{craig}\par.

The second [] is what actually gets typeset?

What is the third [] for?

What is the fourth [] for?

Finally, could you wax philosophic a bit on the meaning and purpose of
\setuptolerance[verytolerant,stretch]? I certainly see that it works, but I
am not sure why.

Thanks.

Hi,

thanks Patrick for the example. The only thing is, that \useURL does not 
hypenate.

In Context there is also a command \hyphenatedurl:

From: 
\hyphenatedurl{http://www.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus:text:1999.01.0218:book=1:line=1}

However you will loose the interactivity.

Another approach is then to use Patrick's example like

\setupoutput[pdftex]
\setupcolors
   [state=start]
\setupinteraction
   [state=start,color=blue]

\useURL
   [hyphenated]
 
[{http://www.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus:text:1999.01.0218:book=1:line=1}]
   []
   [\tex{Odysee from Homeros on the Internet}]

\starttext

Read once from: 
\hyphenatedurl{http://www.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus:text:1999.01.0218:book=1:line=1}

Read also from \from[hyphenated]!

using fonts

[Wolfgang Zillig]

Hello,

I think I´mgetting confused with all of the font selection within context.

First: I have a miktex environment on on W2K.

1.
to change single fonts:
\definetypeface [palatino] [rm] [serif] [palatino] [default] [encoding=ec]
\switchtotypeface[palatino][12pt,rm]
results in an error that the font is not found (font: uplr8t)

on my system following files are available:
uplr8a.afm
uplr8v.tfm
uplr8v.pfb
uplr8a.pfb
uplr8v.htf

but I think tfm is needed

2.
I thought that the default encoding should be texnansi
I tried that but context is looking for texnansi-uhvr8a (here for helvet). The 
font uhvr8a is on my system.

3.
should be there some font-switching macros on the system called font-xxx.tex 
(example font-lbr.tex)? These are missing on my system.
I think these are needed forthings like:
\setupbodyfont[lbr, sans, 12pt]

4.
within miktex there are "lucida" font files from yandy (lbr.tfm
). Is that a free version of lucida-font?
(is that for math? [there is anotherfile called math-lbt.tex in \context\base])


Summary:

do I need to get the missing fonts/files and why are they not provided with miktex.
Perhaps a change of the distribution is to prefer? (which one)

Is there a manual which explains how to change fonts (in a way that a normal 
user who is new to context can understand it)?

Thanks a lot

Wolfgang

That should be OK for all needs.

I have never used \switchtotypeface.

This depends on your setup. See cont-sys.tex as a place where
defaultencoding is sometimes set.

Well the font-xxx.tex files have nothing (not completely true) to do
with the font switching commands.

> 4.

No. There is no really free version of lucida. They once came with
staroffice and there was a script that was able to pull them out and
make them accessable for TeX. But I think that the quality is lower
than the original ones (once read a statement from Walter Schmit about
them, don't remember when and where) and math is not included.

> (is that for math? [there is anotherfile called math-lbt.tex in

No math fonts like lucida for free.

No, go ahead with MikTeX. Try out the stuff that is on the wiki and
please report on your success/failure.

yes and no. See the wiki for links.

\setuptypeface[palatino,12pt,rm]
is probably more appropriate here.

Re: Re: using fonts -- installation

[Rob Ermers]

Dear friends,

Let's join the font discussion!

Two years ago I installed under latex an adapted cyrillic font family, 
along with a new encoding (which I named l2t.enc -- a variant of t2a), 
for  koi8 texts, which makes it possible to call special diacritics 
(like \cyrkdot) by means of regular input codes, such as \= and \d. (In 
this way the text can still be processed without the special font and 
its code, but looks less nice.) As anybody can imagine, it was the 
toughest latex thing I ever did, I guess, but it worked and still does.

I am telling you this because after this complicated job I have been 
trying several times to install a simple type 1 font under Context, the 
last time being two days ago, but without any success. (I got the same 
simple font working under latex, though.) I carefully read Adam's 'My 
Way' over and over again, but I cannot get it work in my system. I put 
all the files exactly on the indicated places! (Texfont is very handy, 
but it seems to me, that nevertheless mapping files are not found.) 
Could anybody give me, and some others, a hand?

The font is simply not recognised (log file message: bodyfont: unknown 
variant johanna). Of course, I am still miles away of getting my 
cyrillic font working under context...

Let's not take the font Palatino, because it's already there, but a 
simple font: say, johanna, which consists of two files:

johanna.pfb
johanna.afm.

Which concrete steps do we have to take to make johanna work under 
Context with Miktex? And, perhaps more important, where do I put my map 
files and font files, etc. so that they be recognised?
The next step would be the installation of a ttf font. After that a 
whole font family should not be that difficult anymore.

Thank you very much in advance!

Kind regards,

Robert Ermers

Okay, that sounds odd. How do you define/use the font in ConTeXt?

Okay, stick those two files in a temp directory together. What happens with:
 texfont --make --install --co=johanna --ve=something --show

?

Re: Re: using fonts -- installation

[Rob Ermers]

Hi Adam,

Thanks for your quick reaction. Before ending this eventful day, I ran 
texexec as you suggested.

The font in question is Hudson (vendor=softmaker = Berry 5), for which I 
  invented the name 5hu (+r for roman). I have the two files 5hur.pdf 
and 5hur.afm.

Texfont generated a number of files and put them in several directories:
- texnansi-softmaker-hudson.map in 
J:\tex\localtexmf\fonts\map\pdftex\context
- texnansi-5hur.tfm in J:\tex\localtexmf\fonts\tfm\softmaker\hudson
- texnansi-5hur.vf in J:\tex\localtexmf\fonts\vf\softmaker\hudson
- 5hur.afm in J:\tex\localtexmf\fonts\afm\softmaker\hudson
- 5hur.pfb in J:\tex\localtexmf\fonts\type1\softmaker\hudson

Texfont also generated the following:
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.log
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.tex
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.tmp
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.pdf

The pdf file does not show the hudson font - I wonder if it should.

Perhaps I should mention that Texfont was interrupted; atf2tfm gets 
stuck - a conflict with a dll, but if click on OK, nothing serious seems 
to be the matter. The tfm file is generated after all. If I test afm2tfm 
  without texfont, it works normally.

I have a test file, which is called testhuds-con.tex.

Kind regards,

Robert

there is support for cyrillic in context but there are many encodings; i'm sure 
that there are users out there who can help

that message is an indication that you didn't define it as bodyfont

for instance:

   \definetypeface[johanna][rm][serif][palatino][default]

will provide

   \setupbodyfont[johanna,10pt,rm]

the combination [serif] [palatino] is the main typescript filter, while [rm] is 
what it gets mapped onto; [default] concerns the size

using fonts -- installation

[r.ermers]

Dear Contexers,

I'm logging in through webmail, so right now I cannot try your suggestions but I will as soon as I get home. I already thank everybody for responding.

I am puzzled by this line which Hans wrote:

\definetypeface[johanna][rm][serif][palatino][default]

Hans further writes that [serif][palatino] is the main typescript filter and that [rm] is mapped on to [serif][palatino]

I don't quite grasp this.

- Why exactly do I have to refer to [serif][palatino]?
- Do you mean that palatino serves as a default which has to be remapped when a new font is installed?
- Where is this status of palatino registered? 
- And why did you chose palatino, rather than another typeface?

Thanks again,

Robert

See earlier in the thread in my message to Wolfgang on typescript filters
and remapping.

It also goes back to the problem I asked about in my earlier message: how
do you actually use/invoke the font in ConTeXt?

Problem with backgrounds and page breaks

[Matthias Weber]

Hello,

when using text background colors in enumerations, I run into a problem
whenever the enumeration appears on the beginning of a page: Then,
the background extends over some part (sometimes all) of the previous 
page.

I can manually correct this by putting a \break just before the 
enumeration, but this
is a little tedious, as I am frequently reformatting the document. 
Below is a small example.

Thanks for any help!

try:

   [before={\testpage[2]\starttextbackground[exbackground]},

that way a pagebreak is forced when less than three lines are left

Thanks, Hans, this fixes it most of the time. But the problem still 
occurs with  one "new line"
less. (Example again at the bottom) :(

in your case the testpage should test for 3 lines, because you have 5pt margin + 
  a blank before it

\testpage[3]

actually the best solution is when i start introducing special background 
options (no time for that now, o for the moment use the testpage); that way i 
can  hook it in the righ tplace

Thanks, that brings it down to two problematic cases in a 400 page 
document,
and I can live with that.

Re: using fonts

Don't worry: it's a bit complicated at first... but it's learn-able (and
easier, to my mind, than LaTeX's way of doing things!).

>First: I have a miktex environment on on W2K.

I don't have miktex. But I'll try to teach what I know!

>1.
>to change single fonts:
>\definetypeface [palatino] [rm] [serif] [palatino] [default] [encoding=ec]
>\switchtotypeface[palatino][12pt,rm]

okay, let's expand through the typescripts a bit:
You invoke these typescripts through your typeface definition (primarily;
there are others that automatically get triggered):
 [serif][palatino][name]
 [serif][palatino][ec]
 [serif][default] [size] % etc...

Serif then gets mapped in type-syn:
\starttypescript [serif] [palatino] [name]
  \definefontsynonym [Serif]            [Palatino] %...

Palatino then gets mapped in type-enc:
\starttypescript [serif] [palatino] [texnansi,ec,8r,t5]
  \definefontsynonym [Palatino][\typefaceencoding-
uplr8a][encoding=\typefaceencoding] %...

This line gets expanded to:
  \definefontsynonym [Palatino][ec-uplr8a][encoding=ec] %...

...So at this point, your system would be looking around for ec-
uplr8a.tfm, but it's not. You provide a clue as to why not:

>2.
>I thought that the default encoding should be texnansi

In the new cont-sys.rme, it's set to ec encoding:
 \setupencoding [\s!default=ec]

...and the berry type synonyms are invoked:
 \usetypescript [berry] [\defaultencoding]

So the following typescript gets invoked, mapping the above ec-uplr8a:
\starttypescript [berry] [ec]
 \definefontsynonym [ec-uplr8a] [uplr8t]  [encoding=ec]

That, being the last one in the chain, is what ConTeXt looks for. For
those following along at home, the whole chain of name resolution, taking
into account the encoding, is therefore:
(\rm\tf) > Serif > Palatino > ec-uplr8a > uplr8t

>on my system following files are available:

That's quite a mixture of types, below. Can you provide a listing of the
.tfm files in fonts/tfm/urw/palatino ?

>uplr8a.afm

(The base Adobe Font Metrics file, which enables you to generate new tfms)

>uplr8v.tfm
>uplr8v.pfb

(Vietnamese variants of the fonts!)

>uplr8a.pfb

(That's the postscript font file you ultimately want to include in your
document.)

>uplr8v.htf

(Irrelevant to our discussion. TeX4ht-related, I think?)

Well, I'm wondering where all the tfms have gone on my distribution, as
well (gwTeX on the Mac doesn't seem to include 8r or ec/8t metrics,
either). It looks like you might have to do a texfont run to build
(ConTeXt-named) tfms in order to be useful.

It's not all that scary. I gave a rundown of the steps I followed in this
primitive MyWay. It might be useful so long as you don't treat it as
literal instructions:

Do you have psnfss (LaTeX) installed?
