Using ZnClient>>#contentWriter
by Esteban Maringolo Feb. 21, 2019

Feb. 21, 2019

Hi all, I'm doing this and it works ZnClient new method: #PUT; url: 'http://127.0.0.1:5984/baseball/2'; contents: (NeoJSONWriter toString: { 'foo' -> 'baz'} asDictionary); contentType: ZnMimeType applicationJson; execute. But if try to use a contentWriter it fails because it can't determine the contentType of the entity. ZnClient new method: #PUT; url: 'http://127.0.0.1:5984/baseball/2'; "contentType: ZnMimeType applicationJson;" contentWriter: [ :entity | NeoJSONWriter toString: entity ]; contents: { 'foo' -> 'baz'} asDictionary; execute. If I uncomment the "contentType:" message send it complains about setting the content type before setting the entity, which makes sense but baffles me. My Idea is to directly pass the object as contents, and let the content writer deal with how it's going to be serialized on the request (a JSON string, for the most part). Although the first expression works, I know it can be done better, but I can't manage to get it working :) Thanks, ps: I also wonder by there aren't #bePut, #bePost, #beDelete, etc. convenience methods instead of passing the HTTP method as a symbol :) Esteban A.

Zinc Error Hierarchy
by Esteban Maringolo Feb. 21, 2019

Feb. 21, 2019

Hi all, Sven, :-) I'm writing some client REST API code and need to handle errors in the call, and found that all Errors are direct descendants of the Error class, why aren't Zinc Errors descendants of a common ZnError class? Regards, Esteban A. Maringolo

Trying to understand Developing with Pharo, Deploying with Gemstone/s
by sergio ruiz Feb. 21, 2019

Feb. 21, 2019

I have an app that is ready to deploy to alpha. I usually do this by creating a script that builds a minimal pharo image, and run that on a cloud server. I then use TelePharo to make any live tweaks that need to happen, and something like: ./pharo Pharo.image "/run/the/script" to keep run cron jobs, etc. I would like to start using Gemstone/s. I got GsDevKithome up and running, with no problems, but I am having a little bit of trouble figuring out how to proceed. I get what tODE is doing, but I donât get how to do the things I normally do: - I got Seaside installed in the image, but I need several other packages in my install: JSON, Soup, AWS S3, etc. How do I go about installing those? - How do I install my main package? Itâs in an Iceberg project. - How do I update my Iceberg project while itâs live? I think those questions will get me into beta pretty quickly.

Buoy <https://github.com/ba-st/Buoy>, the project aiming to complement Pharo <https://www.pharo.org> adding useful extensions reached itâs 5.0.0 version. The supported Pharo versions are 6.1 â 32 bits and 7.0 â 32 & 64 bits.

Hi, We have in our server Gitolite instance running. >From Pharo System browser we commit changes to local path and with TortoiseGit we upload to the remote. So far so good but on Iceberg Repository Status i see "Detached Working Copy". What is the meaning of the message ? The the remote is no been "handle" by Pharo ? Or that the remove is not configured in Pharo ? regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pluralising messages or choosing word alternatives
by Tim Mackinnon Feb. 21, 2019

Feb. 21, 2019

I was browsing some of the Pharo issues (always worth doing) - and noticed an interesting one about Test results reporting and pluralisation (https://github.com/pharo-project/pharo/issues/2578) In it, I hadn't noticed String>>asPluralBasedOn: before (and judging from many messages in the image, many others hadn't either). I'm fixing something similar for a refactoring bug and can use this technique there (although from memory, it comes with a health warning as if ever we want to internalise the messages in Pharo, this will need a different approach). However we are probably a distance from doing that - so cleaning up what we have is a good start. Anyway I was curious if there is something to help with messages like: âThere is 1 occurrence of {1}â vs âThere are many occurrences of {1}â, which Iâd like to write something like: âThere â, (âis 1 â, âare many â) pick: result size, âoccurrenceâ asPluralBasedOn: result size, â â, result printString.

[seaside] adding attributes to link/stylesheet tag
by sergio ruiz Feb. 21, 2019

Feb. 21, 2019

How would I go about rendering this: <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.7.2/css/all.css" integrity="sha384-fnmOCqbTlWIlj8LyTjo7mOUStjsKC4pOpQbqyi7RrhN7udi9RwhKkMHpvLbHG9Sr" crossorigin="anonymousâ> I am not sure how to add the *integrity* and *crossorigin* attributes to the tag..

Re: [Pharo-users] how to test, if the class has "shared identity" of instances in the whole image (SmallIntegers, Symbols...)
by Richard O'Keefe Feb. 20, 2019

Feb. 20, 2019

It is not clear to me what the semantics of such a selector would be. Consider this example: t := [:x | x copy == x]. a := t value: 1.0e38. b := t value: 1.0e308. What do you expect a and b to be? GNU Smalltalk: a=true, b=true. My Smalltalk, 32-bit or 64-bit: a=true, b=true. Squeak/Pharo, 32-bit: a=false, b=false. Squeak/Pharo, 64-bit: a=true, b=false. Squeak/Pharo, after a patch: a=true, b=true. There are two quite different reasons why x copy == x might be true: * x is immutable (including its parts), and can be thought of as a mathematical value, so that there is no need to copy it Examples: every kind of number, characters, booleans, immutable collections, block closures * x is a way of accessing a unique resource, and should not be copied, so making copy the identity is a safety measure. Examples: Semaphores, Mutexes, SharedQueues, data base connections, some kinds of streams, singletons. * Laziness or error (inherited method not revised). What is your use case?
