funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

Postmark email library
by Francois Stephany Aug. 31, 2013

Aug. 31, 2013

Hi guys, I've made a simple wrapper around the Postmark API. It lets you send emails without dealing with a SMTP server. You can read about it here: http://developer.postmarkapp.com/developer-libs.html http://developer.postmarkapp.com/developer-build.html and there: http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark It's pretty simple and naive implementation but it gets the job done. I'll add email attachements when I will need it. Francois

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Re: [Pharo-users] Phaas - anyone interested in setting up Pharo as a Service?

> he, sorry for insist, but cloudfoundry already does that... and is opensource too :) > at ESUG I seen James present it to deploy pharo images... so is viable :) > > cheers, > Esteban > I agree. And, I was really quite optimistic about cloud foundry when it first came out. I particularly like the way you can have a local micro cloud, and then transition to the hosted cloud. My only disappointment was that VMware are not - seemingly - going to offer gemstone as an option on cloudfoundry.com. Building on what Janko said, I think it is really important to join the cloud 'wave'. The question is how might we - collectively - make this happen? I am perfectly happy to go with cloud foundry, or open shift, or any other option if more knowledgeable people can show that X is the way to go. My only requirement is that I don't want to deal with anyone lower than pharo. All OS patches need to be done automagically by the hosting provider. I think cloudfoundry.com and open shift do that, but my understanding of cloudfoundry.org is that this is a 'roll it yourself' solution. Obviously, that would require someone to step up and do that for us. My preference would be for us to create a suitably configured module for one of e platforms, and we can then start getting experience with it. Stephane, is this something that the consortium might take a lead on? My company is happy to pay some of the costs, if this will help. Cheer Andy

Highlighter PetitParser
by Jesus NuÃ±ez April 26, 2013

April 26, 2013

Hello everybody, The following code highlights prolog code statically making use of PPTextHighlighter, I leave the code to share with the community since it might be of help to someone else. Could someone point out how can this be converted to its dynamic counterpart?; The keystroke handler for GLMTextPresentation and what model is currently being used for instance to highlight smalltalk code would be very much appreciated. >From http://bergel.eu/download/Dyla2010/dyla10_submission_4.pdf I know that it might be neccesary a fuzzy highlighter as is written at the end of the code, and it is probably the right object to use but I can not figure out where to plug it. Thank beforehand, Jesus | text textRenderer textShower | text := 'p(Q,R):-q(R), unify_st(X, smalltalk_code), r(T). q(Q):-d(R). q(Q).'. textRenderer := [ PPTextHighlighter new parser: PPPrologParser new; color: 'small_atom' with: Color blue muchDarker; bold: 'small_atom'; color: 'unify_st' with: Color green muchDarker; bold: 'unify_st'; color: 'string' with: Color gray muchDarker; color: 'number' with: Color gray muchDarker; color: 'boolean' with: Color gray muchDarker; highlight: text asText. ].

in anybody out there? who uses 2.0?
by Esteban Lorenzano April 8, 2013

April 8, 2013

Hi, Here in Pharo headquarters we are shock that there are just 10 new bugs reported for 2.0 after the release... So... I wonder... is that because we made a really cool release, or just because nobody is using it? Cheers, Esteban

[ANN] Fuel Release Version 1.9
by Martin Dias April 8, 2013

April 8, 2013

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. [1]: http://rmod.lille.inria.fr/web/pier/software/Fuel [2]: http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.9/Documentation<http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.8/Documentation> We want to thank developers of the community that enrich the project with code, issue reports and ideas. Have fun! Martin (on behalf of Mariano and Max, who worked a lot on this version)

SLOC in Smalltalk
by HernÃ¡n Morales Durand April 8, 2013

April 8, 2013

Hi there, Guys, what are you using to measure logical lines of code (LOC) in Pharo? Given I am measuring a script, is there any other software measure you may recommend? Cheers, HernÃ¡n
