thanks a lot to all who participated on this issue, especially to Khaled for
fixing the internal font processing. Now Palatino font doesn't need to be
patched on client side which simplifies the font setup significantly.

I've updated that Wiki page accordingly. Feel free to correct me.

 explained here:
 http://wiki.contextgarden.net/Palatino_Linotype_under_MKIV
 
 That fix seems to be obsolete nowadays and returning errors.
 

almost fixed now using this procedure:

1) Create a new LFG file

local fix_pala = {
   comment = Switching i.sc glyphs indexes,
   fixes = function(data)
  local descriptions = data.descriptions
  descriptions[983201].index = 1170
  descriptions[983261].index = 1110
   end
}

return {
   name = pala,
   comment = Switching the small capped 'i' to a dotless variant in
Palatino Linotype.,
   treatments = {
  [pala.ttf]   = fix_pala,
  [palai.ttf]  = fix_pala,
  [palab.ttf]  = fix_pala,
  [palabi.ttf] = fix_pala,  
   },
}


2) Place it into the folder where other LFG files are stored
(tex\texmf-context\tex\context\fonts)

3) Execute 'mtxrun --generate' command to include newly added LFG file
into a file database

4) Specify a new font feature referencing to this goodie in the source file:

\definefontfeature[dotlessi][mode=base,goodies=pala]
\definefontfamily[palatino][rm][Palatino
Linotype][features={default,quality,dotlessi}]
\setupbodyfont[palatino]
\starttext
{Athenians \smallcaps{Athenians}}\par
{Athenians \sc{Athenians}}\par
{\it Athenians \smallcaps{Athenians}}\par
{\bf Athenians \smallcaps{Athenians}}\par
{\bi Athenians \smallcaps{Athenians}}\par
\stoptext

5) Trigger the generating

It works except the regular font style. In this case \smallcaps option
behaves differently than for e.g. \it or \bf styles. I am quite confused.
Moreover, when faked caps are switched on using \sc, it works. Can anybody
explain what is happening here?

Thanks, Jan

  This LFG core settings:
  unicodes = {
  [a.sc] = 97, (1)
  [b.sc] = 983261, (2)
  },
 
  (1) replaces all small 'a' into small caps variants - just for
  testing purposes
  (2) doesn't replace small caps 'i' to small caps 'b', but when small
  caps text is selected, b is copied into the clipboard - so some
  replacement is performed, but incomplete.
 
 
 this mechanism assumes that the shapes match the one that unicode
 expects so the (default) tounicode is used ... originally this features
 was meant for fonts with a faulty mapping (some dingbat fonts have
 that)
 

So a different approach is needed. In another thread we've found out that
there are two glyphs of the same name:

glyph index | glyph name
1110| i.sc/ small caps dotlessi
1170| i.sc/ small caps i 

Currently when 'i' is to be rendered as small caps, 1170 is used, but I'd
like to use 1110 instead.

Can this be specified using a LFG file?

Thanks, Jan

there are several ways to apply patches runtime, see *.lfg files (and
also fonts-mkiv.pdf)


1) I've created a sample LFG file
2) placed it into the folder where other LFG files are stored
3) removed pala.tma and pala.tmc files from the cache
4) triggered the generating

My pala.lfg file seems to be ignored:

return {
 name = pala,
 comment = Switching the small capped 'i' to a dotless variant in
Palatino Linotype.,
 remapping = {
 tounicode = true,
 unicodes = {
 [i.sc] = 983201,
 },
 },
}

1) How the LFG file is matched with the font? Is it via the 'name'
parameter, pala in my case? Does that name equals to the file title
without an extension or something else?

2) Should I see that comment in the log or is it just a remark for editors?

3) Can I emulate this patch via direct editing of pala.tma file? When I
change the 'unicodes' value there, it has no impact on generating (nothing
changes in the output).


you have to load them ... see fonts-mkiv.pdf

[NTG-context] Palatino patch for the current ConTeXt version

2013-11-17 Thread honyk
Hello Everyone,

I am trying to fix a Palatino small caps issue using the procedure explained
here:
http://wiki.contextgarden.net/Palatino_Linotype_under_MKIV

That fix seems to be obsolete nowadays and returning errors. 

I've changed 
fonts.otf.enhancers.patches[^pala] 
to 
fonts.handlers.otf.enhancers.patches[^pala]
which compiles, but it does nothing.

I've also tried this variant, but that 'patch' function is never called even
though I clear my font cache every run:

\startluacode
local fonts= fonts
local otf  = fonts.handlers.otf
local patches  = otf.enhancers.patches
local register = patches.register
local report   = patches.report

function patch (data,filename) 
report(I am here)
report(processing data %s, table.serialize(data))
end

register(after,prepare glyphs,^pala, patch)
\stopluacode


Any idea?

Thanks, Jan

patches are applied when a font is cached so you need to wipe the cache 
after defining such a patch


there are several ways to apply patches runtime, see *.lfg files (and 
also fonts-mkiv.pdf)
