[ANN] EventRecorder updated (import/export)

by Torsten Bergmann

Hi, I forgot to mention that for "EventRecorder" there was another pass on the code together with Peter Uhnak. It is now possible to import/export the recordings again and also the UI was updated accordingly (see attached screenshot) Works in Pharo 5.0 - you can load the tool from Catalog or by opening Spotter and entering "EventRecorder". Have fun T.

Re: [Pharo-users] NoSWL Databases

No need for Python or what so ever. There is a tutorial in pharoInProgress on github (attached) a chapter in deepintoPharo book on voyage. Voyage provides a really nice way to handle mongo DB and punqlite for now.

Re: [Pharo-users] Documentation about Pharo Launcher?

by Peter UhnÃ¡k

> prepackaged version of Moose 6 for Windows, Linux y Mac Moose is just Pharo image + changes; you can use the same Moose image on all platforms. And moose is just installed on top of Pharo 5 image (it's just a bunch of commands executed on top of Pharo 5 image https://ci.inria.fr/moose/job/moose-6.0/lastSuccessfulBuild/console ) So you can do it by hand, which is easy, you can download the VMs and sources here http://files.pharo.org/get-files/50/ and just copy there the moose image. I have a bundler that can take a Pharo image and create distribution for each platform together with the correct vm and platform-specific launchers, but I don't really have time right now to clean it up and make it generic (it's for one of my projects)â¦ unless you can wait until after May 15. But you can probably write it yourselfâ¦ it's a bunch of bash, makefiles, C, cross-compilation, and AppleScript. :) Peter On Tue, May 3, 2016 at 7:57 PM, Offray Vladimir Luna CÃ¡rdenas < offray.luna(a)mutabit.com> wrote: > Yes, that would be nice and easier, but I don't know if we have a > prepackaged version of Moose 6 for Windows, Linux y Mac or where I can get > it.

Yes, that would be nice and easier, but I don't know if we have a prepackaged version of Moose 6 for Windows, Linux y Mac or where I can get it. Pointers anyone?

Hi Johan, At this moment I would like the quickest alternative, and maybe what you propose is the path to follow. I have downloaded the Windows and Mac bundles. I imagine that creating my own variant would mean to change the pharo binary, image, sources and changes file in each of them to provide the versions that support the development version of Moose 6, that I'm using now. After that I'll try a better approach using Pharo Launcher.

Can you add arbitrary images and Pharo Launcher will just manage them? No idea, sorry. This is an alternative to Pharo Launcher, I do not know how (if?) it would combine with the launcher. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Re: [Pharo-users] Documentation about Pharo Launcher?

by CÃ©drick BÃ©ler

If you want to reproduce the "preloaded stuff Â» (build one image everyday for instance), youâll have to create first a ConfigurationOfYouApplication describing your dependencies/requirements. Then 2 choices: - you load the configuration in a base image and then you load from the configuration in 1 command (it can be quite quick or take some more time if for instance you need seaside). - if it takes too much time to reproduce or if you want something more Â« serious Â», then once you ConfigurationOf is done, you can setup a job in jenkins (ci.inria.fr - first you need to create an account) so that every night, a new image is created and if no pb, it will be accessible through Â« Pharo Contribution Jenkins" in the Launcher. Anyway, I think you first need to get used to ConfigurationOfâ¦ A convenient tool in Pharo is the Versioner that is a UI around Metacello configuration (=>generating ConfigurationOf). HTH, CÃ©drik

To parse the AST of an expression with the OpalCompiler facade, this is for now: OpalCompiler new source: '[ :a | ^a + 1 ].'; parseExpression Or you can use the parser directly: RBParser parseExpression: '[ :a | ^a + 1 ].â (I am not yet happy with the compiler APIâ¦ but we can only really change it after we get rid of the old one.

So that means you first need to make sure to build a RBMethodNode. expression := RBParser parseExpression: '^[ :a | a + 1 ].'. method := RBMethodNode selector: #myMethod body: expression asSequenceNode. compiledMethod := method generate.
