inferno programmer's notebook

NAME lab 87 - mux for nintendo ds NOTES In an earlier post I talked about updating mux to 4th edition Inferno in the hope of one day running it on a Nintendo DS. Well, Inferno is now booting on the DS so I got to try it for real. I started with getting the mux window manager working in standard inferno. Then I changed the resolution down to 256x192 and tried to get everything to fit. The files in this lab include the version of mux I ended up putting in the nds file running on the DS.

The closest I got was, % load file2chan % calc >[0=1] | {file2chan /chan/desk {rblock; putrdata &} {fetchwdata > /fd/0}} & % stream -b 1 /chan/desk % echo 1+1 > /chan/desk I tried implementing a command equivalent to srv(4) on Plan 9. It takes a command block or network address and post it in the srv registry. % srv {calc >[1=0]} /chan/desk It using an existing '#s' instance if there is one, else binds a new one. Now we can open a console to /chan/desk from another window %
