Quiet in Self land?
by Chris Double 07 Aug '16

07 Aug '16

It's been pretty quiet on this list, so I thought I'd start a conversation to see if the list is working. Anyone doing any interesting Self work? I sidelined my VNC client in Self for a bit due to getting busy in my day job but plan to get back to it soon and finish it off. It's pretty close. The missing part is mostly key handling. I'd like to tidy up my Android patches too and get them submitted so at least Intel android would work out of the box. What do people feel would make Self more viable as a fun project to hack on? -- http://www.bluishcoder.co.nz

Pooi REL
by Baltasar García Perez-Schofield 28 May '16

28 May '16

I've added a new video about Pooi in pure console mode, just text, from within the same jar. So, you can execute it with gui or without it. Just add --nogui to the parameter list. Also Pooi is very verbose, so verbosity is also modifyable from the command line with switch --quiet. The Pooi youtube channel: https://www.youtube.com/playlist?list=PLqgK8lsizKAzuuvSjfWd8iwoHsBGhY2ak The Pooi Read-Eval-Loop pure console text & other goodies: https://www.youtube.com/watch?v=92C_V7zdj78 Example: == $ java -jar Pooi.jar --help --nogui --version Shows version information --nogui Starts a console interpreter --quiet No verbosity --help This help Welcome to Pooi ("os exit" to exit) > os exit == Hope you enjoy them! -- Baltasar

New vídeos about Pooi
by Baltasar García Perez-Schofield 19 May '16

Following the advice of Prof. Ungar, I have improved the visual characteristics of Pooi, you know, my own little object-oriented interpreter implementing the model of prototypes. Hope you like the videos! The new object inspector: https://youtu.be/3MX4vukbflA Explaining inheritance by delegation: https://youtu.be/FkuqkLRKVgs -- Baltasar

VM versioning
by Russell Allen 16 May '16

16 May '16

If you startup the VM from the command line, you will get something like this as the first line: Self Virtual Machine Version 4.1.13, Sun 15 May 16 17:34:42 Mac OS X i386 (4.5.0-101-g6e1af6f) This version number looks like it might be some sort of semantic versioning system (semver.org) or at least a major-minor-patch type of thing. However, it really is Major.Minor.SnapshotVersion In universe.cpp, the versions are set up: // increment VM_snapshot_version whenever old snapshots will break; reset // it to zero when changing the minor or major version smi VM_major_version = 4; smi VM_minor_version = 1; smi VM_snapshot_version = 13; but this comment is I think wrong, because the code only ever looks at the snapshot_version when determining loading a snapshot.: // return for snapshots whose version matches the current snapshot version if (snapshot_version == VM_snapshot_version) return; // Between snapshot versions 10 and 11, a new primitive was added: CompileWithSICNames. // To maintain compatibility, and since there's only a minor addition, we also read // snapshot whose version is 10. -mabdelmalek 11/02 bool can_read_snapshot_with_mismatched_version = (snapshot_version == 10 && VM_snapshot_version == 11) || ((snapshot_version == 10 || snapshot_version == 11) && VM_snapshot_version == 12) || ((snapshot_version == 12) && VM_snapshot_version == 13); if (can_read_snapshot_with_mismatched_version) warning6("\n\tThis snapshot was saved using a different version\n" "\tof the Self Virtual Machine (%d.%d.%d) and may behave unexpectedly\n" "\tor not work correctly with this version (%d.%d.%d).\n", read_major_version, read_minor_version, snapshot_version, VM_major_version, VM_minor_version, VM_snapshot_version); if (!can_read_snapshot_with_mismatched_version) fatalNoMenu6("\n\tThis snapshot was saved using a different version\n" "\tof the Self Virtual Machine (%d.%d.%d) and will not\n" "\twork with this version (%d.%d.%d).\n", read_major_version, read_minor_version, snapshot_version, VM_major_version, VM_minor_version, VM_snapshot_version); So if I increment the minor_version and reset the snapshot_version to 0, then the version checking will have to start looking at all the components, not just the snapshot_version. We should do a new release soon. This should include a newly built VM and to distinguish it there should be a new VM number. So what should we number it? 4.2.0 and change the version checking code? 4.2.13? 4.1.14 and make it read .13 snapshots? 2016.1/13? 2016.1/14? :) Russell

Pooi 1.3
by Baltasar García Perez-Schofield 13 May '16

13 May '16

Hi, Selfers! I've released another version of Pooi. Pooi is a cross-platform object-oriented interpreter, aiming at instructing people on the prototoype model of OO. http://jbgarcia.webs.uvigo.es/prys/pooi/index.html I've created a video, which I think you'll enjoy: https://www.youtube.com/watch?v=mLu3VSrlwIg Hope you like it. -- Baltasar

Self style using JavaScript prototypal inheritance
by owen＠backspaces.net 13 May '16

13 May '16

I'm interested in using JavaScript with the style Self uses: prototypal inheritance, not classical. This is a common issue in the JS community. What's lacking is understanding of the core Self "magic", why it's so successful. I asked about this as an Issue on Self's github page: https://github.com/russellallen/self/issues/57 .. and was pointed to this mail group. JS has good support for prototypal techniques. And several "champions" of its use. (Eric Elliot and Kyle Simpson are the best known) Eric: The Two Pillars of JavaScript https://goo.gl/u7uRV7 Kyle: JS Objects: Inherited a Mess https://davidwalsh.name/javascript-objects ..see Part 3 for diagrams: scroll too "The Whole Pie" & "Looks are everything" What it doesn't have is a Self-oriented guide, how to tease out of JS the success of Self. Specifically, I'm rebuilding http://agentscript.org from a JS dialect CoffeeScript to the newest version of JS, es6. I'm attempting prototypal inheritance but I bet I'm missing a lot! Any pointers to successful prototypal usage that would help JS succeed?

Pooi video demo
by Baltasar García Perez-Schofield 05 May '16

05 May '16

As some of you may know, I have created an interpreter of a prototype-based object-oriented programming language. http://jbgarcia.webs.uvigo.es/prys/pooi/ I've added new functionality (mainly visual), and made a video demo that you could find of interest. https://www.youtube.com/watch?v=mLu3VSrlwIg Hope you like it. -- baltasar
