Re: [Pharo-users] Windows 10 double-click issue + solution

John Many thanks for the tip. I have always found double click very erratic on Windows 7 and now on W10. It would eventually work, but was critically dependent on getting the right timing for the click interval. Pushing the pointer towards 'slow' on the mouse settings has improved things a lot.

Windows 10 double-click issue + solution
by John Kimber Nov. 24, 2018

Nov. 24, 2018

Given the "What FP can learn..." demo, I decided to take another look at Pharo. Needless to say, I'm pleasantly suprised by the progress. The Launcher, in particular is impressive. Soon ran into an issue. On my pc under Windows 10, double-clicks would rarely select a word. Searched the Web, found some links but no real solution. Tried the following.... Under Mouse Properties>Activites: There's a setting for Double-click speed. Choosing the "Slow" value got double-clicks for Pharo working on my PC.

The added complexity of the Cog JIT would put it beyond my skills since the interpreter loop is cycled for every bytecode. In concept, add an instance variable to Process and increment that at the start of every interpreter loop. Can someone comment on the validity of that concept? cheers -ben

Hello, For a acronym maker challenge on exercism.io I have to make acronyms. But I see I have to split the parts on space and when it's a word with a - then I have to split on that, Any hint how I can do that ? Roelof

How to attach a repository
by Nicolai Hess Nov. 24, 2018

Nov. 24, 2018

How can I "attach a repository" to project pharo? In a fresh pharo 7 image I get this message on clicking the "history" button on a method in calypse: [image: grafik.png] btw, the "atttached" has three t's :) And wouldn't it be better, to show an error dialog instead of a debugger stacktrace, if we try to show the history without an repository. nicolai

About the IoT Hackathon last Friday
by Sven Van Caekenberghe Nov. 24, 2018

Nov. 24, 2018

Last Friday we went to the IoT Hackathon in KÃ¶ln and it was a great experience. Thank you Norbert, Christian, Markus and the whole ZweiDenker team for their generous hospitality: the accommodations where great (beautiful office), the food and drinks super tasty, everybody friendly and welcoming. Thank you Allex (Oliviera, Inria/RMOD) for running the workshop and for being so patient, friendly and tireless in helping everyone with all aspects of getting experiments up and running. I knew about PharoThings [1] and TelePharo [2] before, but actually using it in practice to experience connecting software and hardware felt a bit like magic. Thank you Denis (Kudriashov) and Inria/RMOD for developing these packages. Sven [1] https://github.com/pharo-iot/PharoThings [2] https://github.com/pharo-ide/TelePharo

[ANN] JSON schema implementation
by Norbert Hartl Nov. 23, 2018

Nov. 23, 2018

JSONSchema =========== This is an implementation of JSON Schema for the pharo language. It is used to define the structure and values of a JSON string and to validate it. The schema itself can be externalized for being consumed by a third party. I like to announce the availability of a JSON schema implementation for pharo. As part of my implementation of OpenAPI (which is to be released a bit later) I factored out the JSON schema part into its own repository because I think it is useful. I release it even it is not really finished. Code is mostly undocumented and a lot of features are missing from the full spec. I will improve it slowly and add features as I need them or they being requested Hope you like it! Norbert ==== The documentation so far (from https://github.com/zweidenker/JSONSchema <https://github.com/zweidenker/JSONSchema>) It can be loaded by downloading it in pharo via Metacello new repository: 'github://zweidenker/JSONSchema'; baseline: #JSONSchema; load Defining a schema ------------------------- These are the expression to create a schema model inside pharo. schema := { #name -> JSONSchema string. #dateAndTime -> (JSONSchema stringWithFormat: 'date-time'). #numberOfPets -> JSONSchema number } asJSONSchema. defines as schema that can parse the following JSON: jsonString := '{ "name" : "John Doe", "dateAndTime" : "1970-01-01T14:00:00", "numberOfPets" : 3 }'. Reading/Writing a value using a schema ------------------------------------------------------ To parse the value from JSON we only need to invoke: value := schema read: jsonString The object in value will have name as a string, dateAndTime as a DateAndTime object and numberOfPets as a SmallInteger object. The schema can also be used to write out the value as JSON. This is especially useful if we want to ensure that only valid JSON is written. For this invoke jsonString := schema write: value. Serialize/Materialize a schema ---------------------------------------- Addtionally to reading and writing objects a schema can be serialized to string. schemaString := NeoJSONWriter toStringPretty: schema. gives { "type" : "object", "properties" : { "name" : { "type" : "string" }, "numberOfPets" : { "type" : "number" }, "dateAndTime" : { "type" : "string", "format" : "date-time" } } } If we would get a schema as string we can instantiate by invoking schema := JSONSchema fromString: schemaString. Nested schemas ----------------------- Schemas can be nested in any depth. And it can be specified by using the literal Array syntax. schema := { #name -> JSONSchema string. #address -> { #street -> JSONSchema string. #number -> JSONSchema number } } asJSONSchema Constraints --------------- JSON Schema has a defined set of constraints that can be specified. E.g. for a number the inerval of the value can be specified by numberSchema := JSONSchema number. numberSchema interval minimum: 1; exclusiveMaximum: 100 constraining the number value to be greater or equal to 1 and smaller than 100.
