[Pharo-project] WhatsUp from: 2013-03-18 until: 2013-03-31

by seaside＠rmod.lille.inria.fr

Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2013-03-31 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

from the man page: The "sixth" field (the rest of the line) specifies the command to be run. The entire command portion of the line, up to a newline or % character, will be executed by /bin/sh or by the shell specified in the SHELL variable of the cronfile. Percent- signs (%) in the command, unless escaped with backslash (\), will be changed into newâ line characters, and all data after the first % will be sent to the command as stanâ dard input. *hyperventilates* On 18 March 2013 12:40, Damien Pollet <damien.pollet(a)gmail.com> wrote: > not too fastâ¦ I still expected to one this morning :| > > mumble mumble one of these days I'm going to sudo (cat /dev/urandom > > `which cron`) > > > On 17 March 2013 17:53, stephane ducasse <stephane.ducasse(a)free.fr> wrote: > >> thanks damien :) >> >> On Mar 17, 2013, at 4:38 PM, Damien Pollet <damien.pollet(a)gmail.com> >> wrote: >> >> Okâ¦ apparently the day-of-month and day-of-week fields in a crontab do >> not act as AND but as OR.

Now instance of layoutFrame are systematically well initialized. >>> Clients do not need to check against nil values and a new protocol avoids >>> to be forced to specify rectangle when only one number is required. >>> >>> * *Keybindings.* Keybindings is a new library developed by Guillermo >>> Polito to manage key bindings. We started to use it to define widgets >>> keybinding as well as menu shortcut. In Pharo 3.0 we will systematically >>> rewrite all the hard-coded bindings with it and write a documentation. It >>> supports: >>> * source code navigation >>> * running tests >>> * basic refactoring >>> * creating classes >>> * and many more shortcuts: see "Shortcuts Description" in the window >>> menu (triangle on the top right) in Nautilus >>> >>> * *New icons (famfam).* Pharo now uses new icons. We are looking for >>> designers that could help us to define the UI look of the future Pharo >>> versions. >>> >>> * *"Growl" style notifications.* To avoid to get UI blocked by simple >>> notifications, Pharo now uses a growl like notification systems. >>> >>> * *Revamp progress bar.* We started to rewrite the progress bar >>> framework. We introduced the Job class and notification to specify progress >>> bar. >>> >>> * *Rectangle intersection improvements.* Rectangle intersection is a >>> central part for UI redrawing and invalidating screen regions. Rectangle >>> intersection is then an important functionality. We started to address the >>> problem of the non-specification of the intersection of non overlapping >>> rectangles. We introduced the intersect:ifNone protocol. As a side effect >>> this improves the damage recording mechanisms and provide a faster system. >>> >>> ==Developer tools== >>> >>> * *Nautilus browser.* Nautilus, a new code browser has been developed >>> by B. van Ryseghem. It supports: in place hierarchy, groups, refactorings, >>> multiple views, icon navigation and many other features. Nautilus has a >>> plugin infrastructure so everybody can use existing plugin or write new >>> ones. Nautilus is fully navigable using shortcut. In Pharo 3.0 we plan to >>> rewrite Nautilus using Spec. >>> >>> * *Critics browser.* From Pharo 2.0 on we want to systematically run >>> rule checking rules. We revisited the SmallLint rules to customize them to >>> Pharo and we better documented them. We developed a new browser that will >>> helps you to apply SmallLint rules. In particular it supports the notion of >>> todos. We can mark an issue as a false positive or as todos and get the bar >>> green. We wrote a complete chapter on the Critics Browser. We will start to >>> work on an infrastructure to systematically evaluate SmallLint rules on the >>> projects published in the Pharo distribution. >>> >>> * *Omnipresence of the Refactoring Engine.* We believe that Pharo >>> itself should use the best tools it has to change itself. This is why we >>> decided to introduce the Refactoring Engine and SmallLint rule checkers. >>> Note that this move to integrate extra tool is not against our vision to >>> produce a minimal core. Once we have fast fuel based package loading we >>> will be able to remove Metacello from the core. >>> >>> * *Improved version diff browsing.* We improved the diff and merging >>> tool. >>> >>> * *Spotlight.* Spotlight is a ubiquitous tool to find classes and >>> methods. You can activate it just press shift+enter. >>> >>> * *Revamp E/O Completion and smart chars.* In the past, smart >>> characters (automatically closing parenthesis, single quote...) did not >>> play well with auto completeion. In addition, they were duplicated >>> functionality between two automatic ecompletion algorithms. In Pharo 2.0 we >>> unified the two algorithms under a single umbrella and integrate them >>> smoothly with smart-characters. >>> >>> * *Interactive navigation using "ctrl/cmd+click" over >>> classes/methods.* Now Pharo supports the interactive navigation of source >>> code using cmd/ctrl-click on selectors and class names in the source-code >>> [implementors, senders, users]. >>> >>> * *Shout themes.* Several syntax highlighting themes have been defined. >>> >>> * *Andreas profiler.* As a tribute to Andreas Raab, we included an >>> alternate profiler developed by Andreas. >>> >>> ==Networking== >>> >>> * *New version of Zinc.* Zinc is developed by Sven Van Caekenberghe. >>> New versions of Zinc the http client/server library has been integrated. >>> >>> * *Zodiac (SSL).* Zodiac is an extension of Zinc to support SSL >>> connections. >>> >>> ==System== >>> >>> * *System Announcer.* Pharo had a change notification system. A change >>> notification system is important because tools can register to events to >>> update or react without getting coupled with the system. The problem was >>> that the previous change notification broadcasted only symbols and not >>> plain objects. It was limiting the power that we can get about first class >>> objects. In addition not all the events were raised and competing with >>> Announcements (announcements raised plain objects). In Pharo 2.0, we >>> redefined system events as Announcements, introduced a System Announcer >>> whose responsibility is to raise announcement for all the events and >>> removed the old SystemChangeNotifier. This sets up the basis for the future >>> communication between tools. >>> >>> * *RPackage replacing PackageInfo.* PackageInfo is a way to identify >>> if a method belongs to a package. The implementation is based on dynamic >>> queries. Such queries it leads to problems to produce new generation >>> browser and tools. We defined a new implementation of the package >>> management of Pharo. The idea is to represent package as real objects. In >>> Pharo3.0 we will continue to remove the dependency to PackageInfo. >>> >>> * *Manifest: Package metadata.* We introduce the notion of package >>> metadata. Package metadata are used to manage all false positives or >>> todos of SmallLint so that you do not have to check all the time rule >>> results. Each package can now have a class named >>> ManifestNameOfXPackageNameX. It will be the place to add documentation and >>> other information. >>> >>> * *Command line tools / Headless mode.* We really want to make sure >>> that Pharo can be used in non interactive mode and that we can pass scripts >>> to it on the command-line. For this reason we continued to work on making >>> sure that Pharo can be used headless. In particular we introduced a new way >>> to handle command line parameters. See `pharoVM my.image --help` and >>> `pharoVM my.image --list` >>> * st Handle .st source files >>> * Fuel Handle fuel files >>> * config Install and inspect Metacello Configurations from the >>> command line >>> * save Rename the image and changes file >>> * test Run tests from command line >>> * update Load updates >>> * printVersion Print image version >>> * eval Evaluate directly passed-in one line script >>> >>> * *Native boost.* NativeBoost is a library that generates assembly >>> code on the fly. It is used to generate FFI calls. By default [ >>> http://www.esug.org/wiki/pier/Conferences/2011/Schedule-And-Talks/Native-bo…] is included mostly for future use. In Pharo3.0 vector graphics >>> will be used and Nativeboost will be used to invoke the graphics primitives. >>> >>> * *Ring metamodel.* Ring is a new meta model introduced in Pharo 1.4. >>> It is used to represent code that is not currently executed. Ring has an >>> API that is polymorphic with a subpart of the core executing entities of >>> Pharo (Class and CompiledMethod). This has the nice property that the tools >>> that manipulate such entities can also manipulate ring objects. Hence Ring >>> supports of image browsing. In Pharo 3.0 we will rewrite certain tools to >>> use ring and deprecate some abstractions like pseudo-classes and file >>> packages. >>> >>> >>> * *Fuel.* Fuel is one of the fastest and versatile object serializer. >>> In Pharo 2.0, we decided to use fuel as a default serializer. In >>> particular, on error the execution stack is saved now in fuel format. >>> Therefore it is possible to reopen a debugger on a similar image for >>> debugging purpose. >>> >>> * *Freetype fonts.* We offer now a better handling of freetype fonts >>> and their management. >>> >>> * *Metacello: a universal package map.* Metacello is a framework to >>> describe is included in the default image. In the future Pharo will be >>> managed by Metacello. The idea also is that once we have fast fuel based >>> package loading we will be able to remove Metacello from the core. >>> >>> >>> ==Kernel== >>> >>> * *New object-oriented and powerful filesystem.* The old library to >>> support file was dated and cumbersome to use. This version of Pharo uses >>> FileSystem a new framework developed by Colin Putney. We revisited and >>> integrated deeply into Pharo core. A full chapter is available in the new >>> book http://rmod.lille.inria.fr/pbe2/. The work includes a complete >>> removal of FileDirectory. There is a compatibility package to support the >>> transition. Enjoy the new and clean API. >>> >>> * *DateAndTime refactoring.* All the DateAndTime internals are now >>> UTC-based. This prevents bugs in certain edge-cases where the image is >>> moved through different time-zones, most prominently for daylight saving >>> time. >>> >>> ==VM== >>> * Latests cog builds >>> * SSLPlugin >>> * FilePlugin enhancements >>> * SocketPlugin fixes >>> * Included libraries: freetype2, cairo >>> >>> ==Large Cleanups== >>> * *FileDirectory removal.* FileDirectory the old file system has been >>> removed. It is packaged as a separate package to support migration to >>> Pharo2.0. >>> >>> * *Deprecation of old serialization framework.* *ReferenceStream* and >>> *SmartRefStream* are removed. In addition, *DataStream* is cleaned to be >>> only used by Monticello. For a general purpose serializer, use *[ >>> http://rmod.lille.inria.fr/web/pier/software/Fuel Fuel]* instead. >>> >>> * *Large amount of bugs fixes.* You already guessed in addition we >>> integrated *a lot* of small improvements, cleanups and bug fixes. >>> >>> ==Continuous Integration== >>> * *Zeroconf scripts.* Weren't you fed up not be able to install Pharo >>> from a single command line or to pass it arguments? Using a nice debugger >>> and an interactive environment development does not mean that Pharo >>> developers do not value automatic scripts and love command line. Yes we do >>> and we want the best of both worlds! Since Pharo 2.0, Pharo supports a way >>> to define and handle command line argument and offer zero conf scripts. We >>> even wrote a chapter on them. >>> Here is a nice start with a zero-conf bash scripts: `wget --quiet -O - >>> http://files.pharo.org/script/ciPharo20PharoVM.sh | bash` >>> >>> * *CI for everything.* A new infrastructure to support continuous >>> integration is now in place. >>> * First new images and vms are mirrored under >>> http://files.pharo.org/ >>> * Second the key parts of pharo are automatically built on [ >>> https://ci.inria.fr/pharo/] >>> * Third community project can be hosted at [ >>> http://ci.inria.fr/pharo-contribution/] >>> >>> >>> >> > > > -- > > ~~Dr. Jannik Laval~~ > Ãcole des Mines de Douai > Enseignant-chercheur > http://www.jannik-laval.eu > > _______________________________________________ > Esug-list mailing list > Esug-list(a)lists.esug.org > http://lists.esug.org/mailman/listinfo/esug-list_lists.esug.org > >
