beta
by Hans Hagen 18 Mar '11

18 Mar '11

Hi, For those with ftp access .. the new beta version there is somewhat experimental as I rewrote some of the (lua) font code - alternative basemode definitions (context only, experimental) - cleaned up node mode initialization - less memory usage due to adapted data structures - a bit smaller files in the cache - some speedup due to more efficient accessibility - different organization and carry-over of tfm information There will probably be some more changes but I would not be surprised if certain features don't work. This is no big deal and mostly a matter of wrong data access then as nothing changed in the otf processing itself. No testing has been done for the generic variant. This will happen when I'm satisfied with the changes. As the information available in the tfm instance is organized differently one can expect that code that uses it has to be adapted. Anyhow, even after we publish a new beta it is probably good to wait with adapting generic usage till we are stable again.

Math accents
by Khaled Hosny 13 Mar '11

13 Mar '11

Math accents seems to be broken in all OpenType math fonts: * wide accents don't show at all; ConTeXt is looking for non-existent characters (U+FE302 for example). * regular accents don't work with Asana because ConTeXt is looking for the spacing accents which it does not have I think this is left over from the hack of using modifier accents for non-growing ones and combining accents for the growing. Now since luatex introduced new keywords to handle this, I propose that all math accents use the combining accents (which is the right thing to do for all fonts any way) and non growing one would use the new "fixed" keyword. Attached a simple test file. Regards, Khaled -- Khaled Hosny Egyptian Arab

Can't use OTF font with more than 1000 em units
by Khaled Hosny 02 Mar '11

02 Mar '11

With last betas (minimals) I can't use CFF flavoured OpenType fonts with more than 1000 em units, the backed reports the error: !LuaTeX error (file /pth/to/file.otf): Invalid font type It appears this error is reported when luatex encounters a non TTF flavoured font when it expects one (a more explicit error message or at least reporting the invalid type would be more helpful, I think). Checking ConTeXt, I see in font-otf.lua: if units > 1000 then fileformat = "truetype" end Which IMO don't make sense at all since CFF fonts can very well have > 1000 em units. I think this was to work around the bug reported earlier about TTF fonts with .otf file extension, but this is likely to break more other fonts. Renaming the other font is easier, meanwhile neither file extension nor em units is a reliable way to detect spline type (which I think is already known, since Taco has a tracker item for that).
