how the best deal with this
by Roelof Wobben Sept. 28, 2020

Sept. 28, 2020

Hello, I have this code : getMoreData Â Â Â | url url2 json json2 artObjectJson levelsJson| Â Â Â url := 'https://www.rijksmuseum.nl/api/nl/collection/' , objectNumber Â Â Â Â Â Â , '?key=14OGzuak&format=json'. Â Â Â url2 := 'https://www.rijksmuseum.nl/api/nl/collection/' Â Â Â Â Â Â , objectNumber , '/tiles?key=14OGzuak'. Â Â Â "Read the data from the api respons" Â Â Â json := NeoJSONReader fromString: (ZnEasy get: url) contents. Â Â Â artObjectJson := json at: #artObject. Â Â Â painter := ((artObjectJson at: #principalMakers) at: 1) at: #name. Â Â Â title := artObjectJson at: #title. Â Â Â "Read the imageUrl from the api respons" Â Â Â json2 := NeoJSONObject fromString: (ZnEasy get: 'https://www.rijksmuseum.nl/api/nl/collection/SK-C-1368/tiles?key=14OGzuak') contents utf8Decoded. Â Â Â levelsJson := (json2 at: #levels). Â Â Â imageUrl :=Â levelsJson at: 1. but now I see that somethimes ZnEasy get: urlÂ Â gives a document of zero bytes. Now can I put the rest in a big ifFalse block or make another function for it or is there a better more smalltalk way of dealing with this "problem". Roelof

where are the nills come from and how do I get rid of them
by Roelof Wobben Sept. 22, 2020

Sept. 22, 2020

Hello, I have to make a word count from a sentence so I did this : countWordsSentence: aString Â Â Â | splitted result | Â Â Â splitted := aString splitOn: [ :each | ', ' includes: each ]. Â Â Â result := splitted Â Â Â Â Â Â inject: Bag new Â Â Â Â Â Â into: [ :wordBag :word | Â Â Â Â Â Â Â Â Â wordBag Â Â Â Â Â Â Â Â Â Â Â Â add: word; Â Â Â Â Â Â Â Â Â Â Â Â yourself ]. Â Â Â ^ result valuesAndCounts but now I see that the Bag is containing nills. I tried to delete them by doing this :Â Â cleaned := result reject: [:each | each isNil] but to my surprise the nills are still there, Why is that happening and what is the best way to delete them ?

Telegram Bots with Pharo
by Pablo Navarro Sept. 21, 2020

Sept. 21, 2020

Hi everyone, I share a tool for creatingÂ telegramÂ Bots with Pharo. This library provides an interface for theÂ Telegram Bot API. To create our telegram bot in Pharo, the first thing we need to do is to create a new object that inherits from Bottlegram. This object must define at least these three methods: â¢ slashStart: to be executed when the bot receives /start. â¢ slashHelp: to be executed when the bot receives /help. â¢ defaultText: to be executed when the bot receives an unknown command. The tool allows creating bots using two methods: â¢ Using polling: the bot check updates for an amount of time. â¢ Using webhook: Use this method to create a Teapot server to receive incoming updates via an outgoing webhook. Whenever there is an update for the bot, we received an HTTPS POST request to the specified URL Github link:Â https://github.com/pablo1n7/bottlegram If you use Telegram, do you test an echo bot inÂ https://t.me/echo_pharo_bot Saludos, Pablo.

by Sven Van Caekenberghe Sept. 21, 2020

Sept. 21, 2020

Hi, There is a new release of P3, the modern, lean and mean PostgreSQL client for Pharo. https://github.com/svenvc/P3 Version 1.3 contains the following changes: - Add object logging, see the P3LogEvent hierarchy - Added P3ConnectionPool with tests - Better management of prepared statements - Add support for Chronology objects Time, Date and DateAndTime to be used directly as binding arguments for formatted/prepared statements, with tests - Added basic support for array based parameter binding, see P3ValuesArray and #printValuesArrayOn: - Better documentation and fallback for session/connection timezone and character encoder/decoder - Reimplementation of P3Error adding unique codes and #isLocal as opposed to PostreSQL server generated messages; signalling now happens with instances created by class side accessors - Bring back P3Client>>#queryEncoding as an alias for P3Client>>#serverEncoding as compatibility support for PharoDatabaseAccessor - Add P3DatabaseDriver>>#connectSSL: - Various cleanups and internal improvements https://github.com/svenvc/P3/releases/tag/v1.3 The quality of open source software is determined by it being alive, supported and maintained. The first way to help is to simply use P3 in your projects and report back about your successes and the issues that you encounter. You can ask questions on the Pharo mailing lists. I want to thank all contributors and users for their help and feedback: you make a real difference. Since the end of last year, I have been using P3 in a real commercial production context, processing 10.000s of inserts a day and successfully supporting a web application for consulting the data. Enjoy, Sven -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org
