Re: [Pharo-users] Can we have NeoCSV, and NeoJSON included in the base image?

by Andy Burnett

Thanks Ben, and Cyril. I liked Mariano's approach, and I will play with that. However, I think the suggestion about using Moose may be exactly what I need. I have been playing with Mathematica a lot lately, and I really appreciated the fact that you got the kitchen sink with it. What I was wondering - taking Cyril's comment into account - is whether there is an argument for producing a kitchen sink image which contains the stable versions of all the key tools. Obviously, that requires some discussion/analysis of what the key tools are, but it shouldn't be impossible to do. In the meantime, I am off to play with Moose :-) Cheers Andy

You get a lot of people to complain on the mailing list that they need it, then it gets included, unless too many complain that you can easily load a configuration for it and don't always need it. We're working towards a very small core image where everything gets loaded through configurations. With the CI infrastructure we have it is easy to provide personal standard images containing whatever you want. What is stopping you from adding a build 'Andy's Base Image' to the Pharo-Contribution CI? Stephan

Re: [Pharo-users] ZnEasy / UTF-8

by Sven Van Caekenberghe

Hi Volkert, Thanks for the test case, it helped me figure out what the problem was. Basically, what Norbert said was 100% correct: the server code (Teapot) should have specified the charset or encoding of the mime-type it was using (so application/json;charset=utf-8 instead of just application/json). However, I thought I had changed the default to be utf-8, so I was surprised it was not picked up. It turned out utf-8 was the default for reading/writing http messages and their entities, but not so when manually constructing instances (like Teapot did). In code, json := '{''bank'':''RÃ©gion GenÃ¨ve RhÃ´ne''}'. entity := ZnEntity with: json type: 'application/json'. response := ZnResponse ok: entity. response encoder. did not return a ZnUTF8Encoder but a ZnNullEncoder.

That looks cool but I wouldn't hold it up unless we can implement that immediately. Ugly links are better than no links. Of course for Pharo 5.0 with Tx and Pillar we can have pretty contextual links instead of raw text anyway ;) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-4-Playground-open-file-menu-tp4823334p4823783.h… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Can we have NeoCSV, and NeoJSON included in the base image?

by Ben Coman

There are arguments on both sides for whether these are included by default. In general, I understand the goal is limit what is distributed with Pharo, since the ConfigurationBrowser makes loading easy. Moose which is based off Pharo comes with a lot more facilities. In the short term, you might try using a personal-Configuration like this... https://marianopeck.wordpress.com/2011/11/19/loading-projects-and-building-… cheers -ben On Sat, May 2, 2015 at 11:23 PM, Andy Burnett < andy.burnett(a)knowinnovation.com> wrote: > I would find it really useful to have some more classes included in the > base image.

wellâ¦ IMO those scripts also should be in a method. Probably under a class named: MyCoolProjectRunScripts or something like thatâ¦ but in a class. If they are in a class you can: - save them with your project - version them - if you add <script> pragma, you can even execute them by clicking on it (Pharo 4). soâ¦ even if you might have a case where you want the save/loadâ¦ you actually have (what I consider) a better option.
