Hello, all. RMLL2010 was useful for GRUB project too. On one hand it
allowed me to give a speech about it and on the other hand it has
brought new ideas. In particular with Samuel Thibault we discussed
accessibility. Mainstream color defaults are black and white which gives
good contrast and no problems for colorblind people. If distribution
changes these defaults they have to ensure that their defaults Next
step is to help people having either vision or motor problems.
@Samuel: whcih options can we propose for people which aren't blind but
have vision problems?
It's already possible to load bigger fonts.
Now I'm working on braille support. I already coded 40x1 menu selector
and menuentry editor. For 40x1 console I need to add scrolling first.
it's in branches/a11y
I also coded FTDI and PL3203 usbserial drivers. It's in branches/usb.
Now we need the braille drivers to go in-between. I thought of importing
Linux braille drivers since they seem to be under GPLv2+. I hope that I
CC the right list for it. My plan is to have an import similar to what
we have with libgcrypt: we copy the patches verbatim and try to emulate
the environment similar to native one. If any preprocessing is needed we
have 2 directories: one with files as they are imported and another with
the files to compile. The second one is generated from the first one
with python script at autogen phase. This way we avoid forking and can
easily resync
What do you think?

For the record, here is attached a list of the external references of
braille drivers (list-brl, filtered out a bit). Apart from standard C
functions, I can see
- timing functions
- bluetooth functions
- serial functions
- usb functions
- io port functions
- dots/character conversion
- logging
- a couple of helpers like isInteger or reallocWrapper which could
probably be fetched from the brltty source.
- queueing keypresses
Actually, I'm even wondering whether we could just drop support for
braille device keys. Of course, full-fledged support would be great, but
that makes maintainability more difficult.
For the braille translation part, I tried to link together
parse.o file.o queue.o dataarea.o datafile.o ttb_compile.o
ttb_native.ok
and it gave me the second list of symbols (list-ttb). A couple of them
are probably not needed in this context actually (like mkdir).

Another option of course is to just embed the whole brltty code, and
just adding a grub screen driver. That'd be much more demanding in
terms of libc functions (see attached rough list on Linux), as well as
some refactoring of the brltty main loop to make it live along the grub
main loop.

Ok, Dave made the biggest part of it already :)
