Re: [Pharo-users] Fuel transfer from Pharo 1.4 to Pharo 6.1

I feel like we > discussed this before but can't recall the conclusionâ¦ Fuel does handle blocks perfectly, as long as you don't upgrade the underlying Pharo from version 1.4 to 6.1 (or similar big step), like I did... The reason is the change of the bytecodes of a compiled method somewhere between 1.4 and 6.1, which will then not materialize correctly and raises a FLMethodChanged error. Therefore I had to deal with it, like described before. Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch

I had the same wish and came up with the following solution: --- It will calculate the options with a block instead of an already given collection. --- It will recalculate (aka "not cache") the options if you hit the "Save" button on the magritte form. --- It will NOT recalculate the options on the fly when the other dropdown box has been selected. This probably could be done with some ajax stuff or a forced HTTP form send. --- I use my own subclasses for magritte options, for example: MASingleOptionDescription subclass: #ALMaSingleModelOptionDescription uses: TALMagritteOptionDescription instanceVariableNames: '' classVariableNames: '' package: 'Albus-Magritte' --- See attached fileout of the Trait TALMagritteOptionDescription. --- You can then describe an option as follows: descriptionYourAttribute <magritteDescription> ^ALMaSingleModelOptionDescription new accessor: #yourAccessor; optionsBlock: ["stuff to calculate your collection"]; label: 'Your label'; yourself Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch

dependent magritte descriptions

by Peter UhnÃ¡k

Hi, I'm trying to get dependent magritte descriptions, but it seems like this is not something that can be done in the descriptions: Imagine a class Contact with "city" and "country" descriptions. I would like to populate the city description based on the currently selected country ~~~~~~~~~~~~~~~~~~~~~~ descriptionCountry <magritteDescription> ^ MASingleOptionDescription new accessor: #country; label: 'Country'; options: self countries; yourself descriptionCity <magritteDescription> ^ MASingleOptionDescription new accessor: #city; label: 'City'; options: (self citiesInCountry: self country); yourself ~~~~~~~~~~~~~~~~~~~~~~ The problem with this approach is that both descriptions are in the same form, so I need to update the cities list even before the country is saved back into the object. Is this possible in magritte? Thanks, Peter

Re: [Pharo-users] REST client hints

by Ben Coman

Thanks Paul. It'll be good to review some concrete implementations, and nice to see what services other other people find useful. I got a momentary urge the create a Pharo Distribution or catalog entry called something like "SamplRest" with a GUI to explore available REST data sources. Marketing angle for Pharo would be helping less technical people get a "live" hold of data from these sources, and then incrementally script against those live objects. I guess a bit like SegmentIO but on your own desktop rather than through a third party. (but I've not got the time right now) cheers -ben On 6 December 2017 at 02:46, Paul DeBruicker <pdebruic(a)gmail.com> wrote: > Hi Ben, > > > I've made a few REST Clients > > http://smalltalkhub.com/#!/~pdebruic/Stripe > http://smalltalkhub.com/#!/~pdebruic/Tropo > http://smalltalkhub.com/#!/~pdebruic/SegmentIO > > And the elasticsearch one but its been advanced mostly lately by Sho > Yoshida > (https://github.com/newapplesho) here > https://github.com/newapplesho/elasticsearch-smalltalk > > He has also made REST clients for Twilio, AWS, SendGrid, Salesforce, and > Mixpanel among others. > > Norbert Hartl made one for Mandrill (Mailchimps transactional email > service) > http://smalltalkhub.com/#!/~NorbertHartl/Mandrill > > And Francois Stephany made one for Postmark (another transactional email > service) http://smalltalkhub.com/#!/~PharoExtras/Postmark > > > So those are some examples of different approaches. > > > I also started/made a cross platform web client wrapper (just wraps calls > to > ZnClient or WebClient on Squeak) > http://smalltalkhub.com/#!/~pdebruic/HTTPAPIClient > > But IIRC I only used it in the Stripe API client. > > > Hope this gives you some ideas about how to approach your own solution > > Paul > > > > Ben Coman wrote > > I'm just about to write my first client interface to a REST service. > > In some respects I understand this is as simple as doing GET responses > > using Zinc, > > but I'm inquiring about tutorials or libraries that might help.

Re: [Pharo-users] Commander feedback

by Denis Kudriashov

Hi Juraj. Yes. documentation needs to be improved. I made only pass on it. Now there is new Commander version. The code still in dev branch <https://github.com/dionisiydk/Commander/tree/dev>. The basic idea is same but some names are changed and internally it is based on ClassAnnotation's <https://github.com/dionisiydk/ClassAnnotation>. It became more simple and flexible. This week I should release new Calypso version. And after I will work on documentation for both projects. Commander will be first. And next week I will have update on it. 2017-12-05 21:05 GMT+01:00 Juraj Kubelka <juraj.kubelka(a)icloud.com>: > Hi, > > I like the idea of the Commander library https://github.com/ > dionisiydk/Commander > I am trying to understand how to use it, but I struggle to understand it > as documentation includes quiete complex examples: https://ci.inria.fr/ > pharo-contribution/view/Books/job/PharoBookWorkInProgress/ > lastSuccessfulBuild/artifact/book-result/Commander/Commander.html > > I believe that it would be useful to have a tutorial that shows: > > 1. create a command CmdOne including methods, > 2. create a activator ActOne including methods, > 3. create a context CtxOne including methods, > 4. execute <I do not know what> and you obtain a collection with one item > (CmdOne instance?) > 5. create command CmdTwo with some methods > 6. execute <I do not know what> and you obtain a collection with two items > > Then next section could describe how to make a UI on top of this. > Thank's for initiative.

Re: [Pharo-users] Calypso question: adding a context menu item

by Denis Kudriashov

Hi Juraj. I repeated your steps and it works for me: In "vars" mode I have "Say Hello" in context menu of selected variable (just before "Show in method browser" item). Maybe you were looking at context menu of class pane? In that case command activator should be defined as: ClyHelloCommand class>>systemBrowserClassMenuActivator <commandActivator> ^CmdContextMenuCommandActivator byRootGroupItemFor: ClyClassSystemBrowserContext 2017-12-05 18:12 GMT+01:00 Juraj Kubelka <juraj.kubelka(a)icloud.com>: > Hi, > > To implement a context menu item.
