One problem of moving to for instance freetype is that we then need to get at least the same kind of data structures (ok, one could interface compatible using lua, but then I'd end up in a rewrite again, and it makes no sense to spend my live rewriting every few years). In the end I'd still need to construct and cache lua tables in order to be able to do the same (and more). A nice thing about the current fontforge libs (which taco wants to isolate as independent lib too) is that we also have a open source editor that has a similar structure / view on the font. And that was a delibarate choice! Concerning a shaper, it would demand list deconstruction and construction, working within the constaints of the shaper that normally operates on different data structures than node lists, where (i guess) it becomes pretty hard then to do intermediate steps, mess around a bit, bypass etc etc. while in luatex we have a more or less consistent view on matters (read: lists). So, in the end one ends up with a patched shaper to deal with some matters which then defeats the purpose. If we'd have chose a shaper a few years ago, would we switch now? And in 5 years? And in 10? Of course, when we have the swiglib

HarfBuzz is used by much more software projects than what XeTeX was using before (Android, Mozilla, Chrome, LibreOffice, Pango, EFL, to name few), so it is here to stay. That being said, the switch in XeTeX did not affect user documents that much (apart from fixing bugs and supporting more OpenType feature, but so does ConTeXt all the time). However, I’m not proposing that LuaTeX be dependant on HarfBuzz or FreeType, but have an optional font loader and shaper that need not even be managed by LuaTeX team. Fonts change, font formats evolve, Knuth-style stability is not really achievable, unless one freezes the source code and the fonts forever, and you can do this with external libraries, too; TeX Live is self-contained, just take a snapshot and freeze it forever, and it should be buildable as long as there are C(++) compilers.

[NTG-context] bug or needs warning documentation
I found what I consider a bug in startcombination processing.

Examples: 1.) Good compilable source and 2.) source that fails

errors and the error in fact is simply a blank line, which doesn't stand out as
a syntax error in my mind, expecially when white space is supposed to be
ignored by tex/context in usual modes.

Hi all,

2. The commands to select a font have changed to commands which fit better

3. I removed the keys to enable font expansion and protrusion, when you
need them use \definefontfeature.
To use a font with the simplefonts code two ways are available. The first
method is to create
one or more typefaces and load it with \setupbodyfont. A complete example
for this is:

The second method is similar to the old commands of the simplefonts module
(e.g. \setmainfont)
where the font is enabled after it was set and no \setupbodyfont is
necessary. Below is a example
for this method but I recommend to avoid this method because it’s slow
when you set font a font
for each style in your document.

Another feature of simplefonts is the ability to set a fallback font when
you need certain glyphs
from a different font (e.g. for cyrillic ) which aren’t available in the
mainfont of the document.
To set such a fallback font the code provides the \definefallbackfamily
command where you
can set in the fourth argument the range for the replacement characters.
\definefallbackfamily [mainface] [serif] [DejaVu Serif]
[range=cyrillic,force=yes]
What if I want to use the CJK font? The code in font-sel.mkvi hints I
could use range=chinese but it didn't work. I have to use interval
{0x00400-0x2FA1F} explicitly.
And how can I assign the boldfont, italicfont and bolditalicfont? I'm
currently using the Adobe Song Std as the regular font but it didn't come
with a bold version or else, hence I might need this feature.

could use range=chinese but it didn't work. I have to use interval
{0x00400-0x2FA1F} explicitly.
When you take a look into char-def.lua you can see names certain character
ranges and “range=cyrillic”
used such a name.
For a chinese font you need
“range={cjkunifiedideographs,cjkunifiedideographsextensiona,…}.
Because the list with names is very long you do this setup only once with the
\definefontfamilypreset
command, e.g.
\definefontfamilypreset[chinese][range={cjkunifiedideographs,cjkunifiedideographsextensiona,…}]
and load this setup when you set the font with \definefontfamilyfallback, e.g.
\definefontfamilyfallback[typeface][style][font][preset=chinese]
For the moment I added three presets “chinese”, “japanese” and “korean” but
they need better
names, e.g. “range:chinese” because there could be also “features:chinese” etc.
And how can I assign the boldfont, italicfont and bolditalicfont? I'm
currently using the Adobe Song Std as the regular font but it didn't come
with a bold version or else, hence I might need this feature.
The module provides keys to apply a certain font and feature for each
alternative (upright, italic etc.)
of a font, a complete list with all keys is shown in the table below.
---
| Alternative | Font| Feature |
|-|
| tf | regularfont | regularfeatures |
| it | italicfont | italicfeatures |
| sl | slantedfont | slantedfeatures |
| bf | boldfont| boldfeatures|
| bi | bolditalicfont | bolditalicfeatures |
| bs | boldslantedfont | boldslantedfeatures |
| sc | smallcapsfont | smallcapsfeatures |
---
The feature-keys expect the name from the \definefontfeature command, when you
don’t
specify a feature to a certain alternative the value from the “features” key is
used.
When you want to set a certain font for a alternative there are different ways,
I’m going
to show the different ways with a few examples where I change the font for
italic.
1. Use the filename of a font. With the “file:” prefix you can the tell the

Re: [NTG-context] Bug: Reloading Font
On 10/12/2013 12:19 PM, Khaled Hosny wrote: The problem is that OpenType is hard, you already know that. ConTeXt will never be able to dedicate enough resources to catch up with development, so it makes much sense to reuse the efforts of other free software projects. HarfBuzz is used by much more software projects than what XeTeX was using before (Android, Mozilla, Chrome, LibreOffice, Pango, EFL, to name few), so it is here to stay. That being said, the I bet that previous libs and whatever also have that impression .. well, in the end I think that open type will fade away too into something else as its design is sort of a compromise. The dev cycles get smaller each year, the claims for 'being the final solution' get more, who can predict ... switch in XeTeX did not affect user documents that much (apart from fixing bugs and supporting more OpenType feature, but so does ConTeXt all the time). However, I’m not proposing that LuaTeX be dependant on HarfBuzz or FreeType, but have an optional font loader and shaper that need not even be managed by LuaTeX team. once we have a more or less standardized lib loader (the swiglib project) one can use such libraries, i.e. there is no need to have something more in the luatex core; after all, it all boils down to passing info around; anything hard plugged into to core (even options) will be hard to fight if one wants something else at that point i can look into for instance freetype and see if a better loader can be made, who knows ... for me loading and shaping are different things Fonts change, font formats evolve, Knuth-style stability is not really achievable, unless one freezes the source code and the fonts forever, and you can do this with external libraries, too; TeX Live is self-contained, just take a snapshot and freeze it forever, and it should be buildable as long as there are C(++) compilers. well, practice ... one also needs to freeze the operating system then but I'm not claiming that long term stability; there was a time that tex was a big system, but nowadays the tds tree is relatively small; unless something magic happens, i think that at some point the complexity of all these big things will explode (one can according to the evangelists get a ruby on rails app up and running in minutes ... but try to update one a few years later) ... with respect to tex: the source tree/build is not trivial (how many folks know all ins-and-outs?) and it makes me already feel quite dependent .. it's the instability of the whole eco system that bothers me well, the formats don't evolve that much, at least not with respect to what we need in tex ... most features are rather generic, but tex user demands evolve and those will always influence matters; also, in the (context) machinery at some point i want to play with other approaches and then the only thing that matters is having data available (we already have some par optimizing code in place for instance) (i'm more worried about inconsistencies and a mess in fonts than in the opentype standard ... many characters / scripts / languages have well properties, so in fact designers could do with predefined sets of features and rules ... sort of the reverse of making shapes and then the features: instead of for each font reinventing the wheel, choose a set of logic, make shapes etc ... positioning is probably most of the issue then; but that's another disucssion) There are already few parts of OpenType that I’m not able to use in my fonts for years because they break the fonts with LuaTeX horribly. I understand the priorities of the team, that is why I think that offloading font support is beneficial to everyone. break in what sense? what features (just curious) ... anyway, there's always xetex as alternative -) (unless you're referring to wanting to use the microsoft word math renderer trickery -) One problem of moving to for instance freetype is that we then need to get at least the same kind of data structures (ok, one could interface compatible using lua, but then I'd end up in a rewrite again, and it makes no sense to spend my live rewriting every few years). I think that is small price to pay for the gains of not having to worry about every minute detail of OpenType support. Besides doing the shaping with HarfBuzz means that many of the structures exposed by the current font loader will not be even needed, which simplifies things greatly. it all depends on what one wants to do with fonts, what one wants to control, etc but as said, at some point one can consider (either or not as alternative to a lua based variant) to push node list data (in an already existing callback) to a library and get something back .. of course one then also need to take care of possible interferences (assuming that the backend can load the relevant graphic data from the font) In the end I'd still need to construct and cache lua tables in order to be able to do the
