Blocks: Summary
by Dru Nelson 12 Jan '01

12 Jan '01

Thanks Jecel for the great Summary. The trick I was looking for was the read barrier when using blocks. Whenever they are about to be used as an argument for a message send, the 'push' instruction will bind a newly cloned block proto to the current method context (activation record). I was looking for something less expensive :) Dru Nelson San Mateo, California

doc on self vm
by Jecel Assumpcao Jr 31 Jul '00

31 Jul '00

Following the advice Reinald Silveira gave me earlier this year, I have downloaded the Doxygen program which can read the sources for an applications and generate some documentation for it in several formats. You can see the html results here: http://www.merlintec.com/selfvmdoc/ Since my link is very slow, you can probably get better results by downloading Doxygen yourself (there is a link on this page) and running it on the sources to get a local copy of this. I hope this can help people to understand how the virtual machine works a little better. Is anybody still thinking about porting Self 4.1.2 to the PC? After thinking very hard about this I decided that it would be better for me to continue with my self-in-self effort instead. BTW, I will be giving a 12 hour course on Self to students of the Federal University of São Carlos. It will be an official extension course with certificates and all. Luckily they have an aging Sparc or two (mostly black and white X terminals which Self doesn't like, though), but it is a shame we can't use their abundant PCs. -- Jecel

Problem with spy
by tb＠mit.edu 15 Jun '00

I'm using self 4.1.2 on SunOS 5.7. Whenever I start the spy, I get the spy window, which works for a couple seconds, and then my VM hoses, with no response either to the shell running on stdin or the UI. If I delete the spy window, usually the VM then coredumps, but sometimes just continues unresponsive.

self derived language

Brian Rice is developing a new language based mostly on Self, but which tried to include the best features of Beta and a little from Lisp and such. He has some old documentation at: http://www.tunes.org/~water/slate-tutorial.html http://www.tunes.org/~water/slate-home.html and he is updating it at: http://diktuon.arrow.cx/list.php?ns=tutorial http://diktuon.arrow.cx While this is still very preliminary, I thought some people on this list might enjoy his ideas. -- Jecel

mango

I am trying to load the Smalltalk emulator into Self 4.1.2 (I said I would get around to this one day ;-) but it needs Mango in order to generate the parser. The version I have is from 1992 and it include slot privacy declarations (which Self 4 doesn't understand) and an incompatible name space structure. Both problems are to work around, but first I thought I would ask if there are any newer versions available that fix these problems. BTW, I notived that Self 4.1.2 has replaced 'unixFile' with 'unixGlobals os_file'. Any reason for that? -- Jecel
