Dear list,
I have the following sample:
\startluacode
function document.addfunnyhyphen(tfmdata)
local underscore = utf.byte("_")
local char = tfmdata.characters[underscore]
tfmdata.characters[0xFE000] = {
width = 0,
height = 0,
depth = 0,
commands = {
{ "right", -char.width },
{ "down", char.depth },
{ "slot", 1, underscore },
}
}
end
utilities.sequencers.appendaction("aftercopyingcharacters","after","document.addfunnyhyphen")
\stopluacode
\def\CoverImageFile{}%\externalfigure[TypeWriter][width=\textwidth]}
\definefontfamily[ornamenta][rm][FontAwesome]
\def\CoverImageFont{\scale[width=\textwidth]{\ornamenta }}
\def\CoverImage{\doifsomethingelse{\CoverImageFile}{\CoverImageFile}{\CoverImageFont}}
\starttext
\CoverImage
\stoptext
For some reason unknown to me, the only way to compile the sample is to
remove the luacode snippet.
I need the lua code to have underscore hyphenation in type commands. And
I need two extra \definehyphenationfeatures and \sethyphenationfeatures
to invoke it.
Have I hit a bug or what am I missing?
Many thanks for your help,
Pablo

I don't know as i see nothing at all with that code .. this is more fun:
\startluacode
function document.addfunnyhyphen(tfmdata)
local underscore = utf.byte("_")
local char = tfmdata.characters[underscore]
tfmdata.characters[0xFE000] = {
width = 0,
height = 0,
depth = 0,
commands = {
{ "right", -char.width },
{ "down", char.depth },
{ "slot", 1, underscore },
}
}
tfmdata.characters[0xFE001] = {
width = 0,
height = 0,
depth = 0,
commands = {
{ "down", char.depth },
{ "slot", 1, underscore },
{ "right", char.width },
}
}
end
utilities.sequencers.appendaction("aftercopyingcharacters","after","document.addfunnyhyphen")
\stopluacode
\setuplanguage[en][righthyphenchar="FE000,lefthyphenchar="FE001]
\starttext
\input tufte
\stoptext

Many thanks for your reply, Hans,
The following code shows the problem:
\startluacode
function document.addfunnyhyphen(tfmdata)
local underscore = utf.byte("_")
local char = tfmdata.characters[underscore]
tfmdata.characters[0xFE000] = {
width = 0,
height = 0,
depth = 0,
commands = {
{ "right", -char.width },
{ "down", char.depth },
{ "slot", 1, underscore },
}
}
end
utilities.sequencers.appendaction("aftercopyingcharacters","after","document.addfunnyhyphen")
\stopluacode
%~ \definefontfamily[ornamenta][rm][TypographyTribute]
\definehyphenationfeatures[underscore][righthyphenchar="FE000]
\setuphyphenation[method=traditional]
\sethyphenationfeatures[strict]
\setupbodyfont[ornamenta]
\starttext
\hsize\zeropoint
{\sethyphenationfeatures[underscore]\tt pandoc}
A
\stoptext
If you uncomment the line with the font definition, font loading crashes
compilation. It only crashes with this font
(http://www.dafont.com/typographytribute.font) or FontAwesome
(http://www.fontawesome.io).
Both lack the underscore glyph. This causes the crash, since it works
fine if I replace the glyph with an existing glyph in the font.
Error message:
code.tex: ! LuaTeX fatal error error in error handling
\font_helpers_low_level_define ...\scaledfontmode
\relax \ifcase
\scaledfont...
\font_helpers_trigger_define ..._identifier_class
\csname

\applyfontclassstrategies ...\fontface \endcsname
\else \expandafter

\font_helpers_synchronize_font ...classstrategies
\fi \setfalse
\c_font_auto...
\rm ->\ifmmode \mathrm \else \normalrm
\fi
\font_basics_switch_style ...ntstyle #1\endcsname
\edef \fontstyle
{#1}\ifmm...
...
Would it be possible that ConTeXt silently ignores that the font doesn’t
contain the glyph?
I think this might be a bug.
Many thanks for your help,
Pablo

the message is fuzzy (and i have to check a lua stack issue maybe but
not now) ... if char is nil then char.depth is an error

if not char then return end
