Stylistic question: private helper vs extension method?

by Herby VojÄÃk

Hello! I've got this portion in my delegate: requestPayload ifNotNil: [ uuidKeys do: [ :each | requestPayload at: each ifPresent: [ :s | requestPayload at: each put: (UUID fromString: s) ] ] ]. responsePayload := self towergame clientSync: requestPayload. responsePayload ifNotNil: [ uuidKeys do: [ :each | responsePayload at: each ifPresent: [ :uuid | responsePayload at: each put: uuid asString ] ] ]. Now I would gladly use something like Dictionary >> at:ifPresentTransform: aBlock. But it is not present, so I have two choices: 1. Add it as extension method, but then it may clash if someone else has similar idea. 2. Add private helper TowergameDelegate >> dict:at:ifPresentTransform:, which is longer and needs additional self receiver. Which is preferable? Herby

Playground doesn't respect LF endings

by Peter Uhnak

Hi, when I paste a text into the playground with line endings containing just LF (unix-style), then navigation to beginning/end of a line instead jumps to the beginning/end of the text. (I guess it is hardcoded to CR only). Right now I have to execute `Clipboard clipboardText withSqueakLineEndings asString` and then copy&paste the result. Peter

Re: [Pharo-users] Problem with ThreadPool on os windows - no execution

by Paul DeBruicker

Hi Sabine, There shouldn't be any differences between the platforms. Maybe I broke something in the update recently where I make the pool start/stop based on whether it has any jobs. You could try the older version that starts the pool on startup and report back if it works or not. Seems strange that having a halt in there makes it run. Another thing you could do with the current version is open the process browser (e.g. World Menu > Tools > Process Browser) and set it to auto-update then run something like: 1000 timesRepeat:[[100 milliSeconds wait. 1+1] queueWork]. And see if it the ThreadPool wakes up and runs them. If it is working a number of processes that start with the name "pool:" will appear in the list. And then disappear. Up to 15 I think. And I haven't tried the new code on anything but Pharo 5 and don't plan to for a while but would be surprised if that was important.

Re: [Pharo-users] gtInspector override default select behavior

by Evan Donahue

Perfect. Do you know if these methods are systematically documented anywhere? I feel like if I understood Glamour better these things might be more obvious, but I can never manage to infer the gtInspector calls from the Glamour docs.

Re: [Pharo-users] sharing context/variables between multiple playgrounds

by Offray Vladimir Luna CÃ¡rdenas

Hi, I have been thinking in a similar problem for Grafoscopio. In that way, we could have the same persistence among playgrounds in a similar way to Jupyter's persistence among code cells. My bet would be on using the playground bindings that you get when it is executed. In Grafoscopio's case, I'm thinking in storing a them into some kind of ordered set that is available to all notebook nodes... still these are early thoughts and I don't like that the bindings only operate when you have not defined the variable between bars... see screenshot below. So, to add to Peter's question: - There is any way to access not only variables bindings in a playground, but all variables that are declared there, once it is executed? - How can tap into the playgrounds self-completion behavior, so it can read variable names stored in a particular place?

Re: [Pharo-users] Fetching https site content with Zinc

by Esteban A. Maringolo

Hi, Probably, the hashbang (#code) is causing the front end proxy to respond with a 400 error. It works if you do: ZnEasy get: 'https://etherscan.io/address/0xbcff2d15c698d3874bc29aa170c89fd7a6146a4b' However, I think there might be an specify REST API to get the Solidity code of that SmartContract. Also, you can use an available Pharo driver for Ethereum: https://github.com/sbragagnolo/Fog I'm not familiar with Ethereum, but according to Fog's docs you can get the contract doing: FogConnection eth getContract: 'ContractHash' blockTag: 'latest' Regards!

Fetching https site content with Zinc

by Henrique Rocha

Hi there, I am trying to automate the fetching of a site content in Pharo. Basically, I want to fetch smart contract information from Etherscan. Here is an example URL: https://etherscan.io/address/0xbcff2d15c698d3874bc29aa170c89fd7a6146a4b#code I tried to use Zinc to fetch that, here is my code (very simple): ZnEasy get: 'https://etherscan.io/address/0x9C169d81420aAD7D8a0D6d9F295C3ba2C33575De#code' Although it runs without errors the fetched content is "Bad Request - Invalid URL" and not the actual website. Anyone know what am I doing wrong here? -- View this message in context: http://forum.world.st/Fetching-https-site-content-with-Zinc-tp4959072.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
