Kom question (was Re: HttpView2 1.1-beta available on Squeak Map)

Hi, I noticed in the newest version of TcpListener that you changed the listen code from binding on all ports to only binding on localhost (127.0.0.1). What are the reasons for this? It is hard coded, so I have to either change the code or set up a local address translation rule.

ScheduledControllers - is an UndefinedObject !!!

ScheduledControllers - is an UndefinedObject !!! could not reproduce problem. Hi Theo, I brought up a Squeak 7137 opened an mvc project. Copied the code from the wiki to a workspace in the project. Selected it and pressed Cmd-d to doit. The result was an untitled window with the polyspiral drawn inside. So what did I do different from what you did? Cheers.

Does one have to go back to an earlier version to use Wonderland with Squeak? I saw some stuff in the archives but nothing conclusive. ===Blake===

[ANN] Exupery 0.12 release
by bryce＠kampjes.demon.co.uk 04 Nov '07

04 Nov '07

This release * Has a background compiler that can be run for about a hour * Has many bug fixes * Merges in David and John's 32 bit clean work and makes Exupery 32 bit clean. Installation instructions and links to VM's and pre-built images are here: http://wiki.squeak.org/squeak/3945 To use the background compiler: First initialise Exupery to prepare the code cache. This will also clear out any currently compiled code. Exupery initialiseExupery Then start the background compiler using the following expression. Exupery startBackgroundCompilation. Then when done use the following to stop it. Exupery stopBackgroundCompilation. Thanks to Andy Tweek and Mathieu Suen for building the Windows and Mac VMs. The Mac VM was built with gcc optimisation switched off to avoid a bug in gcc 4.0 so it's probably much slower than the normal VM. This is still an alpha release, running the background compiler will lead to crashes, but it should run for long enough to play with. The next release will improve both the profiler that drives background compilation and reliability. Bryce

[ANN] new version of SuperCollider-Morphs for Squeak
by Cesare Marilungo 03 Nov '07

03 Nov '07

Hi, I just published a new version of my little hack/project, and I finally made a small tutorial. It is a collection of morphs for using Squeak as a programming/experimenting/performing environment for SuperCollider. Download and tutorial: http://www.cesaremarilungo.com/sw/supercollider-morphs-for-squeak New features/fixes: - sclang syntax highlighting (preliminary :-) classes names are hard coded atm) - now you can nest knobs and sliders inside a container - knobs :-) - the stout from the sclang process is now redirected in the Transcript window as soon as it arrives. Cheers, - c. -- www.cesaremarilungo.com

There is a .net bridge for corba. For inter-image messaging, sockets can be used, or magma, the object database.

[ANN] new release of MEPS parser combinator
by squeakdev1＠reider.net 03 Nov '07

03 Nov '07

A new release of MEPS is available on SqueakMap. MEPS is a parser combinator for squeak that allows parsers to be combined and evaluated through a set of matching extension methods in PositionableStreams eg: 'foobar' readStream match: 'foo' and: 'bar' regex action:[:r | FooBarNode foo:r first bar: r second ]. where 'foo' and ('bar' regex) are parsers defined on the fly. This release provides additional ways to combine parsers separate from their invocation. The following example creates a parser of a Smalltalk method temp declaration: whitespace := '\s*' regex. id := '\a\w*' regex. ids := (whitespace , id ! [ : r | r second]) zeroOrMore . temps := '|' meps , ids , whitespace , '|' ! [:list | list second]. temps << '| foo bar |' "anOrderedCollection('foo' 'bar')" (This example is somewhat contrived because in a real Smalltalk parser, tokenizing and parsing would occur in separate phases (each of which could be created using MEPS)). In ids, a whitespace parser is combined (#,) with an identifier parser. Then #! yields a parser with an action that transforms {ws,id} to id, which is then used in a repetition parser created by #zeroOrMore. temps << | foo bar |' is equivalent to '| foo bar |' readStream match:temps action:[:r|r]. ids could have been written equivalently as: ids := [:input | input matchZeroOrMore: [:in2 | in2 match: whitespace and: id action: [ : r | r second]] action:[:r |r ]]. (Note: in this release, block parsers no longer have to capture the input stream). See http://squeak.reider.net/MEPS/meps.html for more examples.
