Cosmacs: A Personal Voyage
Jeff Dlouhy
COSMACS
=======
Cosmacs now works with very simple input and will print out the command that a key is bound to. I also have it working where it will dispatch on that key/command as well. The current roadblock now is interpreting control characters from the terminal and converting them to use our keystroke record type. This again deals with porting over code that is in calias.scm (bucky bits) and input.scm. I'm moving slowly in this area until I get a better grasp of the tty.
Example Cosmacs Output:
KEYSTROKE: (kbd (backspace)) COMMAND: delete-backward-char
KEYSTROKE: (kbd (1)) COMMAND: self-insert-command
One error semi related to this is that tty-info in Scsh 0.7 is broken. See http://code.google.com/p/scsh/issues/detail?id=6
TERMINFO
========
While banging on the latest trunk of Scsh 0.7, Roderic and I came across a few bugs in Duncan's Terminfo library that broke with the move to the latest Scheme48. We think these were related to s48's new OS-String system and Terminfo assuming it always be receiving an 8-bit char. Also Roderic fixed a bug on Ubuntu.
* 45541fd - (HEAD, master) Use the i/o package's READ-BYTE (2 weeks ago)
* a31c720 - Fix terminfo finding in Ubuntu. (2 weeks ago)
EDWIN48
=======
In addition to working on Cosmacs, I have spent a significant amount of time on restructuring some of the package files as well as cutting down on the number of duplicate imports in various structures. Anyone who loads up the scratch-load.scm file will know that there is still a ways to go until more of the warnings are gone.
One insanely helpful little tool lately has been Taylor's "Apropos" (http://mumble.net/~campbell/scheme/s48-apropos.scm)
Here is an example of using it:
Welcome to scsh 0.7
Type ,? for help.
> ,exec ,load scratch-load.scm
> ,open apropos
> (apropos-all 'comtab)
