Re: [Pharo-users] Smalltalk Programming Competition

by horrido

I hear what you're saying. Here's my rationale... #1. As far as I know, I'm the only person on the planet who has worked full-time and without pay as a programming language advocate for nearly four years. Did I mention full-time and without pay? So I think you can trust me to deliver, come hell or high water. #2. For the past four years, I've shown my marketing skills in promoting Smalltalk. If you believe I've done a good job, then you can trust me to convince schools and the media to stand behind the competition. If you don't believe, then ignore me; I cannot convince you otherwise. #3. It is not my style to plan everything in advance and in detail. I do things by the seat of my pants, relying on my organizational skills, communication skills, and intuition. (That's how I develop software, too.) I can picture the whole competition in my mind and I trust my vision. I'm asking others to trust it, as well. If they don't, then this whole thing dies with me. In the final analysis, all I can do is my very best. I am who I am. If you don't believe in me, that's okay.

Re: [Pharo-users] Iceberg - finding deleted classes, reverting versions?

by Tim Mackinnon

Guille - just following up on this thread as Iâd like to get more confident with this stuff. You mentioned a Calypso plugin for versions - where is that? I loaded a recentish P7 image and I donât see those icons? Is this something I can easily load to try out? As I donât have that plugin, Iâve followed up on your next suggestion (just to learn how to do this) about looking up a commit having used the command line git history to list all of my deleted classes (I think this might be a useful thing to add to Iceberg BTW). Not sure how to get a repository but I cobbled together the following? (IceLibgitRepository registry detect: [ :r | r name beginsWith: 'Prismic' ]) lookupCommit: '65363adâ. This give me an IceGitCommit - but then what can I easily do with this to try and iterate over deleted classes to try and get the one Iâve identified back? Failing all of this - I went back to the command line again (which should work) - and Iâm really wondering if we do something weird with files or paths when checking in? Having got a valid commitID (I used: git log --diff-filter=D --summary âpretty="format:%cd|%h|%cn%n%s%nâ ) if I simply run the following (with the id and pathname taken from the output of my previous command git checkout 65363ad src/PrismicDemo/PrismicBlock.class.st <http://prismicblock.class.st/> I keep getting an error : error: pathspec âsrc/PrismicDemo/PrismicBlock.class.st <http://prismicblock.class.st/>' did not match any file(s) known to git. Are you able to confirm if you can restore a deleted class from a commit? Iâve tried it on 2 different OSX machines and neither of them works - making me think we do something odd.

Re: [Pharo-users] Smalltalk Programming Competition

by horrido

The first attempt at a competition was a Kickstarter campaign. No money was collected, because Kickstarter is an all-or-nothing affair. (In other words, you didn't actually lose any money.) Cincom had pledged $5,000, but because it was all-or-nothing, they wriggled out of it. Otherwise, we could've run a downscaled competition. I've learned from that mistake and chosen to use GoFundMe. If necessary, I shall run a downscaled competition, assuming that I get reasonable funding. The last thing I want to do is run a chintzy peanuts contest; it would do absolutely nothing for Smalltalk.

One small correction: it's CA$30,000, not US$30,000. Given the exchange rate, it's actually considerably LESS money!

The issue is reported here: https://github.com/pharo-project/pharo-launcher/issues/115 The reason is that the uninstaller only uninstalls files it created. PharoLauncher should not create any file into its installation folder. I think we could do that when we switch to Pharo 7.0 for Pharo Launcher. Vincent did some work in this direction.
