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 ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

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 \v_font_identifier... \applyfontclassstrategies ...\fontface \endcsname \else \expandafter \font_h... \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.
