Contribute an implementation into Pharo, which bypasses the problem of clashing with someone else's package, when they have a similar need they'll benefit from it already been done. That is assuming such would be a generally useful feature. It sounds like it to me, but could someone else support that? Keeping in mind its good to encourage newcomers to step up to being a contributor and not just a user - expanding the circle of "Pharo Is Yours" Note though, this will probably only be integrated to Pharo 7. So you'll need your Baseline to conditional load it for Pharo 5/6 - but thats a good thing to practice anyway (someone else will need to advise how to go about it - I'm still getting up to speed on this) cheers -ben

Re: [Pharo-users] PetitParser: Parse X as long as it's not Y

by Sean P. DeNigris

Peter Kenny wrote > This seems to be what the PPAndParser is designed for. Thanks for the pointer, Peter! I finally figured it out based on your example. To get more concrete, I'm trying to parse a name, where the end of the input might be an optional middle name, followed by an optional generational (e.g. 'Paul III'). What I think the restricted line says is: "peek to make sure we don't have a #gen, then try to parse an #identifier". Interestingly the order is important. If the peek and identifier are reversed, it tries to peek after the identifier, causing an error when there is only a middle name (i.e. no more input). identifier := #letter asParser plus flatten. gen := 'Jr' asParser / 'Sr' asParser. restricted := gen negate and, identifier. parser := ((#space asParser, restricted) optional, (#space asParser, gen) optional) end. parser parse: ' Paul Jr'. parser parse: ' Paul'. parser parse: ' Jr'. This really had me baffled. Thanks again!! ----- Cheers, Sean -- View this message in context: http://forum.world.st/PetitParser-Parse-X-as-long-as-it-s-not-Y-tp4958895p4… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

The extension is directly relevant to dictionary-ness, so an extenstion makes sense. But, I would go with a different name and a more familiar pattern: #transformAt:using: and #transformAt:using:ifAbsent:. You would use the latter, with an empty block for the #ifAbsent: keyword. The former, if you chose to implement it, would throw an /element not found/ exception if the key is not in the dictionary. I think it helps when the verb begins the behaviour name. Admittedly, there are numerous cases where the symmetry is more important, as with #at: and #at:put:. (But, probably because they are short.) > 2.

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.
