Mantis usage rules du jour
by tim Rowledge 19 Feb '14

19 Feb '14

I'm submitting a bug fix and thought I'd ask what the current favoured procedure is. Simply submitting is as irritating as it ever was in Mantis, but once I've done that, uploaded my fix and made a note about it… what do we do next? To whom might I assign it for action in getting into the image for the next release? Or is that done some other way now? Is there documentation on the current process that I failed to spot? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: XO: Execute Operator

Re: [squeak-dev] The Inbox: Compiler.quasiquote-eem.248.mcz

Hi All, I had fun implementing a quasi-quote for Squeak today. This is a convenient way of embedding substrings in format strings (a little like printf), and, because it uses a different quote character, a convenient way of embedding code form other languages in a string literal. An example of the former usage is `hello [#cruel] world` which evaluates to 'hello cruel world' And `Float pi is [Float pi]` evaluates to 'Float pi is 3.141592653589793' An example of the latter use is that one can write `printf("%s: %c\\n", "a string", 'C');` instead of 'printf("%s: %c\n", "a string", ''C'');' This last example shows a limitation; The use of \ to escape characters ($\ $[ and $`) in quasi-quote might not be such a good choice. Anyway I thought I'd put this in the in-box for people to play with and savage. Please let me know what you think, both about the semantics and the implementation. This is a quick hack and I'm sure that there's plenty of scope for clean-up. cheers Eliot On Tue, Feb 5, 2013 at 9:54 PM, <commits(a)source.squeak.org> wrote: > A new version of Compiler was added to project The Inbox: > http://source.squeak.org/inbox/Compiler.quasiquote-eem.248.mcz > > ==================== Summary ==================== > > Name: Compiler.quasiquote-eem.248 > Author: eem > Time: 5 February 2013, 9:54:20.317 pm > UUID: ef044906-3339-48cc-856b-9b5172e3e81b > Ancestors: Compiler-cwp.247 > > Add a quasi-quote form that allows convenient embedding > of substrings within a format string, and provides a > convenient way of embedding literal strings within an > alternative literal string whose string delimiter is different. > > e.g. > `hello [#cruel] world!` > evaluates to > 'hello cruel world'. > > `S1[B1]...SN[BN]SN+1` > > is equivalent to > { 'S1'.

Loading FFI is broken
by Frank Shearar 20 Nov '13

20 Nov '13

(Installer monticello mc: (MCHttpRepository new location: 'http://source.squeak.org/FFI')) install: 'FFI-Kernel-eem.24.mcz'. "There's a -tbn.25, but that's not important to this post" fails with an MNU: ExternalFunction class >> callingConventionFor:. As far as I can see what's happening is this: * during the loading of the mcz ExternalFunction is defined, * a method is parsed (#XOpenDisplay, which has a pragma <cdecl: X11Display* ''XOpenDisplay'' (char*) module:''X11''>) * Parser >> externalFunctionDeclaration checks whether ExternalFunction is defined. * It is, so tries to evaluate `descriptorClass callingConvention: here` and boom, because ExternalFunction class >> callingConventionFor: _has not been loaded yet_. I've seen this kind of issue with Helvetia code: sometimes you simply have to load class-side methods first. Thoughts? Lukas worked around the issue with his Helvetia code by directly patching Monticello, and ripping out its "try to do atomic loading" mechanism. frank

Phexample on Squeak
by Frank Shearar 21 Jul '13

21 Jul '13

Hi Niko, I tried Phexample in Squeak and things work great. I had to load in Regex-Core, but that's no biggie. I'll try my hand at editing the ConfigurationOf and send you a patch. I have only one blip: ForExampleStack >> #shouldFailWhenPopEmpty fails because instead of 'this collection is empty' the example fails with 'this stack is empty'. I'm not sure how to fix that, given that it's not your problem. One easy way to get a green bar would be to change the error message in Squeak (making it less accurate). Any thoughts? frank

Two things about the implementation: - using #isOctetCharacter is not good enough. When I wrote ascii, I meant the 7-bit US-ASCII characters.

There is GetText-Editor and GetText-Localization There is in addition a package System-Localization which contains classes like ISOLanguageDefinition, InternalTranslator, Locale, NaturalLanguageTranslator Bert, is what you mean done by exchanging GetText-Editor --> System-GetTextEditor GetText-Localization --> System-GetTextLocalization How should the translation registry class be named? --Hannes > > >

Fwd: [ANN] Fuel Release Version 1.9
by Martin Dias 08 Apr '13

08 Apr '13

Hi all, We are happy to announce Fuel 1.9. Fuel is an open-source general-purpose object serialization framework developed in Pharo. You can find more information on our website [1]. The default set of packages of this version already comes in Pharo 2.0, so you it's not necessary to install it there. However, Fuel also works out-of-the-box in Pharo from 1.1 up to 2.0, as well as in Squeak 4.1 up to 4.4. You can see our documentation [2] for complete installation and use guides. Changes: - (feature) DoIt and not-installed CompiledMethods are fully serialized by default. - (fix) Date & DateAndTime (thanks Cami and Marcus) (already included in Fuel 1.8.1 and 1.8.2). - (feature) New hooks methods #fuelNew and #fuelNew: for custom instantiation (see "Hooking instance creation" in Customizing the Graph). - Globals: - Added #globalEnvironment: to specify where the globals are looked-up. (see "Changing the environment" in Managing Globals). - Explicit references to "Smalltalk globals" changed to "self class environment". - A SystemDictionary instance is not treated as global when it is not "Smalltalk globals". - Documentation: - General update - New Format Migration section. - New Built-in Header Support section. - (feature) Put back FLSerializer>>on:. - (optimization) New clusters for SmallInteger. - (optimization) New clusters for most common collections. - (feature) Built-in support for header (See Built-in Header Support): - pre and post materialization actions (clean closures). - attach additional objects. - materialize only the header. - (fix) Safer substitutions (see FLPluggableSubstitutionTest>>testPrivateExcluded). - (feature) Materialize .fuel files when drag&dropped in the image. - (cleanup) Removed unneeded cluster: FLWellKnownObjectsCluster.

Have fun! Martin (on behalf of Mariano and Max, who worked a lot on this version)

Everyone's talking about debuggers these days
by Frank Shearar 08 Apr '13

08 Apr '13

First it was Gilad Bracha - http://gbracha.blogspot.co.uk/2012/11/debug-mode-is-only-mode.html - and now John Nolan - http://stigmergist.blogspot.co.uk/2013/01/debugger-first-vm-development.html I also saw a really neat demo of a framework for debugging system calls. I hope to find out more about this when I quiz the implementor in early February. I would be less vague if I could remember the name of the framework! frank
