Previous format was unusable. New format is ranges of hex values.
To choose space character and Latin capital letters for example:
$ fc-pattern ':charset=20 41-5a'
Pattern has 1 elts (size 16)
charset:
0000: 00000000 00000001 07fffffe 00000000 00000000 00000000 00000000 00000000
(s)
It was added without proper measurement and a fuzzy possible
use-case (font servers) in mind, but reality check shows that
this significantly slows down caching. As such, deprecate it
and do NOT compute hash during caching.
Makes caching two to three times faster (ignoring the 2 second
delay in fc-cache).
This is more robust but introduces a small change in behavior:
For .pcf.gz fonts, the new code calculates the hash of the uncompressed
font data whereas the original code was calculating the hash of the
compressed data.
No big deal IMO.
FcTypeVoid is likely to happen when 'lang' and 'charset'
is deleted by 'delete' or 'delete_all' mode in edit.
Without this change, any modification on them are simply
ignored.
This is useful to make a lot of changes, particularly
when one wants to add a few and delete a lot say.
This feature requires the FreeType 2.5.1 or later at the build time.
Besides <range> element allows <double> elements with this changes.
This may breaks the cache but not bumping in this change sets at this moment.
please be aware if you want to try it and run fc-cache before/after to
avoid the weird thing against it.
Version section was getting confused to the API's availability,
even though it was the version the doc was genereated.
So moving it into the footer and added @SINCE@ field in the data.
Let me show it with an example.
Currently:
$ fc-match symbol
symbol.ttf: "Symbol" "Regular"
$ fc-match symbol --sort | head -n 1
Symbol.pfb: "Symbol" "Regular"
$ fc-match symbol --sort --all | head -n 1
symbol.ttf: "Symbol" "Regular"
I want to make sure the above three commands all return the same font.
Ie. I want to make sure FcFontMatch() always returns the first font
from FcFontSort(). As such, never trim first font.
