I would defer to Seaside experts on this, but I would say yes to Seaside REST in general and Teapot REST otherwise if it meets your requirements . I have not worked on them for a long time now.

Pharo consortium selected for GSOC 2019

by Serge Stinckwich

Dear all, Pharo Consortium has been selected this year as a Google Summer of Code 2019 mentor organization. This is the first time since 2017. I would like to thank other GSOC co-admin Jigyasa Grover and Oleksandr Zaytsev for their commitment and hard work, Peter Uhnak for his help for the website, Alexandre Bergel, Yuriy Tymchuk and StÃ©phane Ducasse for their interactions. We will prepare the call for students soon. We have already a website with a list of subject: http://gsoc.pharo.org/ More subjects can be added, but we will focus on topics that will have the bigger impact on the Pharo community. We will use the #gsoc-planning channel on Discord to discuss. If you have students that might be interested, please let them know about this opportunity. There is #gsoc-students channel for them.

Re: [Pharo-users] Windows 64bit, long filename issue but after a second load, how to categorise and report this?

by Tim Mackinnon

Iâve been able to find out more information about this - and have now got the full filename and error in question: `'C:/Users/sam/Documents/Pharo/images/exercism-test-run-7.0-32bit/pharo-local/iceberg/dionisiydk/StateSpecs/StateSpecs-DSL-PragmaBasedShouldExpressions-Tests.package/SpecOfShouldExpressionDriverTests.class/instance/testRaiseUnexpectedMessageWhenTooMuchMessages.st': The filename or extension is too long.` So the path is 262 characters long. (hence the error) The package this file is in, is a downstream project prerequisite for PharoWebBrowser - which is dragged in because that project doesn't have different groupings for code and tests (something I am working with Sean to try to get resolved - although Iâm scratching my head on how you can test baselines?). We don't see this in the image in OSX because the included baseline doesn't actually pre-req these pragma based tests? However from below, have I now understood that when we reference a project, we end up cloning the whole repository for that repo on disk (so one big read), and then metacello picks out the relevant files from the baseline. So possibly, this might be some orphaned files/packages in the repo - that iceberg no longer knows about, but git does? The longer term fix is to convert PharoWebBrowser to Tonel and see if we can improve the grouping.

Re: [Pharo-users] Display MozCanvas on screen?

by Tudor Girba

Hi, Look for the examples that are shipped with GT/Brick/Bloc/Sparta. The simplest way you play with the canvas is through the inspector. For example, paste this code in a Playground: canvas := BlSpartaMozCanvasBuilder extent: 600@400. canvas fill paint: Color white; path: canvas bounds; draw. path := canvas path moveTo: 150@50; lineTo: 250@250; curveVia: 150@300 to: 50@250; close; finish. canvas stroke paint: Color red; path: path; strokeOptions: (canvas strokeOptions width: 5); draw. canvas Then inspect the result (Cmd+g), and choose the Preview view from the inspector.

Google Protobuf and usage of Slots

by Holger Freyther

Hi, from my point of view the pillars of future services are Google protobuf[1] and gRPC. Protobuf can be used for configuration files[2], tracing/logging[3] and storage[4]. gRPC is built on top-of HTTP2 and is using the protobuf IDL and marshaling. Many projects (etcd, envoy, Google Cloud, ...) provide a gRPC based API (and some automatically map this from REST to gRPC) already and I would like to build clients and servers in Pharo. My plan of action is to start with a protobuf compiler/model and then look into binding the gRPC C implementation to Pharo. I have started with gokr's Protobuf code on Smalltalkhub and defined base types and a Slot and could use some help to structure this more nicely. The code is at: https://github.com/zecke/pharo-protobuf and I could use some comments/review of how to use Slots in a significant way (add "type" validation on write, constraint checks, builder pattern?). Given a definition like: syntax = "proto2"; package foo; enum Color { RED = 0; GREEN = 1; BLUE = 2; } message MyMessage { optional Color color = 1; } And an encoded binary message of #[8 2] the following can: PBTestMessage materializeFrom: #[8 2] readStream decode and set the color field. Proper handling of mandatory and repeated fields are missing and decoding the other values, nested messages... :) Looking forward to have some eyes on the code. holger [1] A simple IDL to define structs/enums with marshaller/materializer for a binary protocol, JSON (and yaml). [2] Without having to write a XML/JSON schema and getting validation from the IDL. [3] Many of us log structured to text, then have something like logstash to re-parse, regexp it and dump it into ElasticSearch. With protobuf we can have plain objects end to end for logging. [4] We have FUEL so this is less interesting for us than others but quite interesting if you are mixing Pharo with other implementation languages.

Hi, Finally i found a much more acceptable solution :) neoJsonMapping: mapper "Map the receiver from a json with <NeoJSONObjectMapping> <mapper>" mapper for: self do: [ :mapping | mapping mapAccessor: #locator mutator: #setLocator: to: 'booking'. ]. setLocator: aDictionary locator := aDictionary at: '@locator' regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] NeoJSON mapping question

by BrunoBB

Hi, The following implementation do what i want without the need to create a class for each level of the JSON, however i really dislike my solution. neoJsonMapping: mapper "class side" "Map the receiver to a json with <NeoJSONObjectMapping> <mapper>" mapper for: self do: [ :mapping | (mapping mapProperty: 'booking' getter: [:obj | obj locator] setter: [ :obj :value | obj setLocator: value]) valueSchema: self. ]. mapper for: self do: [ :mapping | mapping mapProperty: '@locator' getter: [:obj | obj locator] setter: [ :obj :value | obj locator: value] ] The first part map 'booking' property to the class locator inst var. The second part have access to the "second json level" and the value i'm looking for. But setLocator: anObject is the ugly thing :( setLocator: anObject (anObject class == PmsJsonInput) ifTrue: [^locator := anObject locator]. locator := anObject I'm sure there must be another way to do this. regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

NeoJSON mapping question

by BrunoBB

Hi, How to set a path to JSON value in the mapping definition ? I mean i have a simple object with and instance variable but the value of this inst var is deep inside the JSON. mapping mapInstVar: #locator to: 'locator'. This fail because 'locator' is not in the first JSON level. Is possible to do something like: mapping mapInstVar: #locator to: 'booking.vars.locator'. I already tried and fail. But i was not able to find something similar. regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

This is fine: www.bagelconcertfinder.com/zipcodes/{zipCode} Preferred is : *https://......siteName.../boundedContext/resourceInPlural/{resourceId}* So this can be as you state but without _ underscores and "concertBlogging" is identified bounded context for a set of resources https://....siteName../*concertBlogging*/blogs/{blogId} Plurals are recommended.

Re: [Pharo-users] What does the Package and Sub-Package comment do?

Hi Tim. Behaviour is similar to Pharo 6. When class is selected the comment belongs to the class. If not then it belongs to the package. There is no such thing as a tag comment. I thought the default comment text is clear enough to avoid confusion. But probably it's not as you wrote this mail. So it is a room for improvements. Package comment is managed as a comment of ts manifest class.
