[NTG-context] issue mixing font features (LMTX & MkIV)

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \definefontfeature[wider][extend=2]

  \definefontfamily[mainface][rm][TeX Gyre Pagella]
[features={default, quality, wider},
 it={style: regular, features:{default, slanted, quality}},
 bf={style: regular, features:{default, boldened-30}},
 bi={style: regular, features:{default, boldened-30, slanted}}]

  \setupbodyfont
[mainface, 30pt]

  \starttext
  \startTEXpage[offset=1ex]
  a
  {\it a}\\
  {\bf a}
  {\bi a}
  \stopTEXpage
  \stoptext

With current latest (2024.02.27 09:21), LuaTeX gets boldened and slanted
for regular (but the other fonts cannot inherit the wider feature and
wider will not mix with boldened-30 [even when specified]).

For some reason, LMTX from current latest cannot get slanted and
boldened-30 (but it mixes the inherited wider feature in all fonts).

This began to behave differently in latest from 2024.01.08 11:23 (which
is my next version after the one from 2023.09.26 18:19).

Could anyone confirm the issue?

Many thanks for your help,

Pablo

Many thanks for your fast reply, Hans.

The thing with that font is that it contains polytonic Greek and other
scripts.

Many thanks for your help,

Sorry, Hans, but I don’t remember. These two months are being demanding
and my memory is far from being perfect.

I think my problems were related to glyph shapes. But in any case, if I
detect what I think it might be a bug, rest assured I’ll report it.

I wonder why the first font feature ("effect") doesn’t work. What am I
missing?
because effects are not regular features so you need to create a new

instance (which makes sense as you cannot turn a regular font into an
italic or bold one either this way)


Many thanks for your explanation, Hans.

The new font instance is what I was missing in many of the issues I had
with features.

Even if the font is on the same directory as the ConTeXt source file? I
invoke it by its file name.

Sorry, this was outside the ConTeXt tree. And I didn’t know that it has
to be indexed by ConTeXt.

Loading font by filename whoch are in the same directory as your document
works only with typescripts but \definefontfamily has to look in the 
index even

when you the file-method to ensure the requested font is available.

Many thanks for your reply, Wolfgang.

I wanted to avoid the installation of the font, because I had another
version of GaramondNo8 already installed.

So, I renamed the font and installed it. Everything works fine now.

Many thanks for your help,

Wolfgang,

I’m afraid that even with that, I’m afraid it doesn’t work well:

\definefallbackfamily[mainface][rm][Latin Modern Math]
[tf=file:newg8-regular, scale=0.88, range=0x22C0]
\definefallbackfamily[mainface][rm][Latin Greek Math]
[tf=file:newg8-regular, range=preset:greek]
\definefontfamily[mainface][rm][Latin Modern Roman]

\definefontfamily[mainface][ss][GaraMath][tf=file:newg8-regular]

\setupbodyfont[mainface]

\starttext
α ⋀ {\tt α} a{\ss a}b{\ss b}c{\ss c}g{\ss g}
\stoptext

If another "key=value" pair is specified, "tf=file:newg8-regular"
doesn’t seem to work.

What am I doing wrong?
Don’t write just some garbage as third argument for the 
\definefontfamily or \definefallbackfamily commands.


In the attached picture you can see the fonforge information for the

needed for the \definefontfamily command is the "family name" value.

Same results (no font embedding) with latest stable version from the
ConTeXt Suite.

If you want me to, I can attach the font itself in a private message (it
is URW Garamond [no copyright infringement, unless you plan to sell it
;-)]).


i think Wolfgang has to answer it .. he knows that define*family 
mechanism better

Same results (no font embedding) with latest stable version from the

If you want me to, I can attach the font itself in a private message (it
is URW Garamond [no copyright infringement, unless you plan to sell it
;-)]).

The weird thing here is that the Lua code isn’t applied to the

Is there a way to fix this strange interaction?


in that font the underscore has no depth, so:

{ down, char.depth or 0 },
{ slot, 1, underscore },

[NTG-context] issue with font sizes

[Pablo Rodriguez]

Dear list,

I have the following sample:

\definefontfamily
[anothersans]
[ss]
[DejaVu Sans]

\starttext
\tfxx smaller text with \anothersans\ss second sans.
\stoptext

I need to add an alternative ss and tt font. The problem is that when
changing the typeface, I get the normal font size.

Is this a bug or a feature? How could I avoid it?

Many thanks for your help,

[NTG-context] issue with font in typing environment

[Pablo Rodriguez]

Dear list,

I converted the monospace fonts of txfonts
(http://www.ctan.org/tex-archive/fonts/txfonts/pfb) from pbf to otf
using FontForge. They work fine (http://www.ousia.tk/ryfonts.zip).

But the issue is shown in the following sample (beta from 2014.02.01 14:22):

\definefontfamily[mainface][mono][ryt1xtt][bf=ryt1xbtt]
\setupbodyfont[mainface]
\definetyping[TeXcode][option=TEX]
\starttext
\starttyping
\ConTeXt\ is
\stoptyping
\startTeXcode
\ConTeXt\ is
\stopTeXcode
\stoptext

If option=TEX is enabled, there is no space after the backslash.

I have checked the font and it seems to work fine, so it might be a bug.

Many thanks for your help,

Pablo

\stoptypescript

\definetypeface [mainface] [rm] [serif] [txfonts] [default]
\definetypeface [mainface] [tt] [mono]  [txfonts] [default]

\setupbodyfont[mainface]

\starttext

Regular, {\bf Bold} and {\sc Smallcaps}.

\starttyping[option=tex]
\CONTEXT\ is wonderful!
\stoptyping

\stoptext


Even though this is something that should be fixed using a different font
in truetype/opentype format solves your problem as well. The following
two fonts are similar to the monospaced font of the txfonts package:

- http://www.fontsquirrel.com/fonts/Luxi-Mono
- http://www.fontsquirrel.com/fonts/pt-mono

Is there no way to tell what is wrong in the font, so it could be fixed?

BTW, I’m afraid I cannot compile your sample.

I think the missing space in the font is the problem because after I replaced
the visible space with a normal space there was also a space after the backslash
in the typing environment.

 BTW, I’m afraid I cannot compile your sample.

My example uses the type1 version of the font from CTAN, you have to put
the afm and pfb files into the fonts folder of your tex directory.

You are right. The space was missing in the font. I defined it and it
