For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe,
|
||
|
|
as a widely used and tested shaper is used as more-or-less OpenType reference
|
||
|
|
implemenetation and that specially is important where OpenType specification
|
||
|
|
is or wasn't that clear. For having access to Uniscribe on Linux/macOS these
|
||
|
|
steps are recommended:
|
||
|
|
|
||
|
|
1. Install Wine from your favorite package manager.
|
||
|
|
|
||
|
|
2. And `mingw-w64` compiler.
|
||
|
|
With `brew` on macOS, you can have it like `brew install mingw-w64`
|
||
|
|
|
||
|
|
3. Download and put [this](https://drive.google.com/open?id=0B3_fQkxDZZXXbWltRGd5bjVrUDQ)
|
||
|
|
on your `~/.local/i686-w64-mingw32`.
|
||
|
|
|
||
|
|
4. Replace all the instances of `/home/behdad/.local/i586-mingw32msvc`
|
||
|
|
and `/home/behdad/.local/i686-w64-mingw32` with `<$HOME>/.local/i686-w64-mingw32`
|
||
|
|
on that folder. (`<$HOME>` replace it with `/home/XXX` or `/Users/XXX` on macOS)
|
||
|
|
|
||
|
|
Probably you shouldn't replace the ones are inside binaries.
|
||
|
|
|
||
|
|
5. `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild`
|
||
|
|
|
||
|
|
6. `../mingw32.sh --with-uniscribe && cd ..`
|
||
|
|
|
||
|
|
7. `make -Cwinbuild`
|
||
|
|
|
||
|
|
Now you can use hb-shape using `wine winbuild/util/hb-shape.exe` but if you like to
|
||
|
|
to use the original Uniscribe,
|
||
|
|
|
||
|
|
8. Bring a 32bit version of `usp10.dll` for youself from `C:\Windows\SysWOW64\usp10.dll` of your
|
||
|
|
Windows installation (asuming you have a 64-bit installation, otherwise `C:\Windows\System32\usp10.dll`)
|
||
|
|
that it is not a DirectWrite proxy ([for more info](https://en.wikipedia.org/wiki/Uniscribe)).
|
||
|
|
Rule of thumb, your `usp10.dll` should have a size more than 500kb, otherwise
|
||
|
|
it is designed to work with DirectWrite which Wine can't work with its original one.
|
||
|
|
|
||
|
|
Put the dll on the folder you are going to run the next command,
|
||
|
|
|
||
|
|
9. `WINEDLLOVERRIDES="usp10=n" wine winbuild/util/hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe`
|
||
|
|
|
||
|
|
(`0061,0062,0063` means `abc`, use test/shaping/hb-unicode-decode to generate ones you need)
