do-it or inspect-it in the spotter search bar?

by PAUL DEBRUICKER

I was feeling lazy was wondered if it would be possible to hit Cmd-D or Cmd-I in the spotter input field rather than opening a playground and typing something in then hitting it. E.g. 1 + 1 Cmd-I would open an inspector on the number 2 After looking at GTSpotter>>#spotterFor... methods I couldn't figure out how to make it happen in the half hour I had to spend on it. I recognize opening the playground is Cmd-O Cmd-W but I just open the spotter ~50x as often as a new playground so the muscle memory isn't there. If I could do quick one-liners in the spotter then the playground would get opened even less often.

safely determining whether ProcessWrapper process is running

by Peter UhnÃ¡k

Hi, I feel like I am missing something obvious, but is there a _safe_ way to test if PW is still running? If the process pointer for whatever reason is no longer valid (e.g. the image crashed / I closed image), then #isRunning results in crashing the image. Maybe this is a bug? Thanks, Peter

Awesome, we need more projects in git! Nicely timed as I was just about to mentor someone in Smalltalk and we were going to use polymath to see if he might contribute something.

Re: [Pharo-users] Tonel Fileout

by Tim Mackinnon

I think the tests for Tonel reader/writer do exactly that in memory trick - so I think we could get a no e soln. But to get 1.0 I think we get a menu item running with import/export and then we can in parallel write examples and build out a better integration. Would be nice to show we can play in the same pools as the other children ;) Tim Sent from my iPhone Sent from my iPhone On 30 Jun 2018, at 09:24, Ben Coman <btc(a)openinworld.com> wrote: >>>> On 16 Jun 2018, at 15:38, Ben Coman <btc(a)openInWorld.com> wrote: >>>> >>>> Le 16/06/2018 Ã 10:43, Ben Coman a Ã©crit : >>>>> How can a fileout/filein be done using Tonel format? >>>>> In the first case as a script? >>>>> and secondly as a possible menu option for Pharo? >>>>> >>>>> This is to facilitate transfer of student coding exercises for Exercism. >>>>> http://exercism.io/languages/pharo/launch >>>>> >>>>> Could Tonel handle a full package export in one file? >>>> >>>>> On 16 June 2018 at 17:13, Hilaire <hilaire(a)drgeo.eu> wrote: >>>>> Hi Ben, >>>>> >>>>> I am not sure, but the purpose of Tonel is to propose a file representation of "one class=one file". >>>> >>>> Sure thats how Tonel came about, and its how we mostly use it, but is this an inherent limitation? >>>> Each method is prefixed with its class, so from my 100ft viewpoint it seems feasible to transport a whole package in one Tonel file. >>>> >>>> >>>>> Why not using Fileout st files to transfer the code? >>>> >>>> The same question might be asked why Iceberg didn't just use a Fileout at class level. >>>> The Tonel format is more readable, especially minus the scattering of exclamation marks. >>>> >>>> I also meant to ask, what methods are used to file-in a Tonel file ? >>>> Or more the point, what method process a string in Tonel format that has been downloaded from a website? >>>> >>>> Actually, hunting around a bit I found.... >>>> >>>> TonelParserTest >> testMethodDefList >>>> shows that...
