Code completion in Pharo?

by andreo

Dear Pharoers, I'm just starting out with Pharo 6.1, and I'm trying to use code completion to interactively explore various objects and their messages. However, I'm having difficulties doing this efficiently - I think I must be missing something obvious, and I hope you can point me in the right direction. For instance, let's say I have the below in Playground: 'some text' asMorph and I would like to display the morph object as a window, but I don't know the exact message name, or whether such a message exists at all. If I type "Window", then the completion popup will show a long list of matching messages, but won't show their documentation or argument names, so it will be difficult to know exactly what these messages do. I can see that one can do "Do it and go" on an expression and then browse the available messages in Meta, but maybe there is simpler/faster way? How would an experienced Pharo user typically go about discovering the right messages in such situations?

BlueInk Pretty Printer Array Formatting

by Evan Donahue

Hi, I've just discovered that I can change the auto-formatter settings and I'm trying to figure out how I can make array syntax behave nicely. If I write: a := {1. 2. 3. }. The formatter keeps it all on the same line. This is what I want. However, if one of those constants is a variable, as in: a := { 1. 2. b }. It breaks the whole array up across multiple lines, as shown, which quickly becomes unreadable for nested arrays. Is there some setting I can tweak to make it keep the array all on one line? Thanks, Evan

Re: [Pharo-users] Reverting changes in Iceberg

by Guillermo Polito

Hi Even, what Pharo version are you using? What Iceberg version (the one that comes by default)? If you're in Pharo 6 with the default iceberg version, I'd suggest you to: - update iceberg - or just fix it from the command line $ git reset --hard HEAD~1 should do what you want. If you already have latest iceberg release (because you loaded it, or you are in Pharo 7), that can be done from a playground but not (yet) from the UI. You can try: - right click on your repository -> inspect - Then evaluate: self branch commit: self branch commit parent. self headCommit adopt. Which will do exactly the same as the command line reset --hard does.

Reverting changes in Iceberg

by Evan Donahue

Hi, I was trying to merge changes from a collaborator from github into my local image and, through some flurry of menus I didn't quite comprehend, it seems to have blown away their changes and left me a commit ahead with all of their changes deleted. How can I revert back to their change, which I do see in my history, and continue from there without my erroneous most recent commit? Thanks, Evan

Handling socket timed out

by Hilaire

Hi, With this code, the ConnectionTimedOut exception is never handled: | socket data | socket := Socket newUDP. socket setPort: 51284. socket waitForDataFor: 5. data := ByteArray new: 100. [[socket receiveUDPDataInto: data] Â Â Â on: Error Â Â Â do: ['Catched error, closing socket' crLog. socket closeAndDestroy]] Â Â Â ensure: [ 'Closing socket' crLog. socket closeAndDestroy] Any reason it does not work? In Pharo I see several examples using ifCurtailed. Hilaire -- Dr. Geo http://drgeo.eu
