[Pharo-project] [ANN] Brltty support for Pharo

by Goubier Thierry

Hi, I have created a project and release a start for connecting Pharo to Brltty, the software layer handling braille keyboards under Linux. This is the first step which could allow a blind user to use Pharo. The project is hosted on ss3, at: http://ss3.gemstone.com/ss/StBrltty.html At the moment, this code is only able to authenticate with the brltty server, not yet able to display anything (it's hard to read the brltty source code to guess the protocol used). There is some overall design to be done, because a braille keyboard is a fairly complex device (with input / tty keys, not a pure display device), even if my blind colleague is perfectly fine using it only as a display device and navigating with a normal keyboard. There will be a bit of Morphic adaptations to be done as well, such as keyboard navigation (it's not working very well at the moment in Pharo 1.3 and 1.4). I have the start of a proposal for funding, but I can't push this forward; I do believe an internship (L3/M1 in the french system) would probably be enough to get it to work. I do have a test setup : a user and two Braille keyboards with different characteristics. So, if anybody is interested to take over me ?

Nicolas, I just tried adding a project, "Ma-Core" but it said only letters and digits are allowed. Am I supposed to camel-case it? Why this restriction?
