Problems with the pscyr font package

Problems with the pscyr font package

[Radhelorn]

Hello All!
I'm fresh ConTeXt user, trying to move from LaTeX. And I have several
problems with fonts in ConTeXt 2005.06.07 (teTeX-3.0).

First of all: pscyr. It's a cyrillic type1 font package which works
perfectly in LaTeX, but in Plain TeX and ConTeXt whitespaces between
words disappear.

My input files:
Test font.
\font\myfont=fcori6a
\myfont
Test of font. Some text to test it.
\bye

and ConTeXt:

\mainlanguage[ru]
\useregime[cyr]
\enableregime[koi8-r]

\definefontsynonym[somefont][fcori6a][encoding=t2a]
\definefont[myfont][somefont]

\starttext
Test of text.
\myfont
Test of PSCyr text.
\stoptext

What I'm doing wrong?

I can't find any LaTeX package on CTAN except as a BaKoMa install
package, and my system teTeX does not have 'fcori6a.tfm'. Under
those circumstances, it becomes quite hard to help you with your
problem. There may be a clue buried in the latex support macros ?

Well, I've already looked at this. AFAIK no magic there:
from tex/latex/pscyr/pscyr.sty:

\def\codefault{fco}
\DeclareRobustCommand\cofamily
         {\not@math@alphabet\rmfamily\mathrm
          \fontfamily\codefault\selectfont}
\DeclareTextFontCommand{\textco}{\cofamily}

there is also definition of bold math mode and
\renewcommand{\hbar}{{\mathchar'26\mkern-8.5muh}}

from tex/latex/pscyr/t2afco.fd:

\DeclareFontFamily{T2A}{fco}{}
\DeclareFontShape{T2A}{fco}{m}{it}{<-> fcori6t}{}

from fonts/map/dvips/pscyr/pscyr.map:

fcori6a  CollegePSCyr-Italic "T2AEncoding ReEncodeFont" <t2a.enc 
      <colle8.pfb

Encoding file fonts/enc/dvips/pscyr/t2a.enc, but pdftex ignores 
ReEncodeFont, as stated in documentation.

Hope this helps.

So you should use fcori6t in ConTeXt as well. You are using the
wrong metrics, and that is the cause of the disappearing space.

Pdftx does do the actual re-encoding, it just ignores the
supplied string value.

Oh, thank you, I see it now. But how font filename and basename is 
resolved from map file if tfm in source and in map file differ? If LaTeX 
uses *6t for T2A encoding, but in map file there is only *6a, how it 
works? I've reread the docs, but this moment remains unclear.

The *6t tfm's works as expected, I'm just trying to understand what all 
this files doing.

Yes, I figured it out from experiments.

This is because of virtual fonts:

Thanks, this explains the situation. Is there a command to trace font 
loading? Which files are loaded, etc.

Nothing that would help you understand it better, I'm afraid. There is
a way to trace file opne/file close in the search library,  but you
have to be an expert to understand the output of that I'm afraid.

Thank you for the explanation. Now I make typescript file for the 
package and have some problems with math, but I will try to get through 
this myself.
