Hi Hans,

It seems like the char-def.lua code is not merged into luatex-fonts-merged.lua. It causes:

! LuaTeX error ...-context/tex/generic/context/luatex-fonts-merged.lua:5690: attempt to index global 'characters' (a nil value)

Also (after deleting that line since "chardata" is not actually used anywhere), node mode does not seem to work:

\input{luatex-fonts}

\font\testa={file:xits-regular:mode=node;+liga} at 45pt \font\testb={file:xits-regular:mode=base;+liga} at 45pt \testa fi fl ffi ffl\par \testb fi fl ffi ffl\par \bye

I uploaded a version without the chardata reference Anyhow, I do see ligatures here so I wonder what goes wrong at your end. ----------------------------------------------------------------- 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 -----------------------------------------------------------------

Now the fontfallback hangs up. For example,

\definefontsynonym[song][name:adobesongstd] \definefontfallback[hereos][name:texgyreherosregular][0x0000-0x0400] \definefontsynonym[fbsong][song][fallbacks=hereos] \definefont[newsong][fbsong]

\starttext \newsong 夹杂 English 的中文文本 \stoptext

The error message is:

! LuaTeX error ...text/tex/texmf-context/tex/context/base/char-ini.lua:311: bad argument #1 to 'gsub' (string expected, got nil)

Is "0x000-0x0400" replaced by somthing?

It seems like a typo in the line 315 in char-ini.lua. "local range = characters.blocks[tag]" or "local range = characters.blocks[name]"? -- Best regards, Li Yanrui (李延瑞)

Anyhow, I do see ligatures here so I wonder what goes wrong at your end.

I updated minimals but still I get ligatures only with base mode, I even built the luatex-plain format and used luatex binary from minimals. If I process the file with context, I get ligatures in both cases. Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
