Re: [Pharo-users] stfx.eu down

by Offray Vladimir Luna CÃ¡rdenas

Hi Sven, Thanks for the heads up. stfx has been really useful when sharing playgrounds in workshops and hackathons, and of course we can wait until modernization ends.

Re: [Pharo-users] Unable to compile myself Pharo

by Ben Coman

That sounds normal. "No stash" is not an error. You should see new files in directory ".git/hooks" which help give correct date to built VM to avoid "to old" message. btw, make sure you match your 32/64-bitness between VM and Image. cheers -ben On Tue, 11 Dec 2018 at 00:51, Alexandre Garreau <galex-713(a)galex-713.eu> wrote: > Le 07/12/2018 Ã 02h25, Ben Coman a Ã©crit : > >> On Fri, 7 Dec 2018 at 01:43, Alexandre Garreau <galex-713(a)galex-713.eu> >> wrote: >> >>> I built the VM and when running the Pharo.image file got with curl by >>> the site, it runs but warns the VM is too old for this image (strangely, >>> since I built the git version), >>> >> That warning can occur if you didn't run "scripts/updateSCCSVersions" >> once on your fresh clone (as described in the repo README, but its a common >> miss) >> >> I recloned and did it, and it doesnât seem it did something, as it pretty > quickly ended with only that output: > > galex-713@portable:~/doc/comp/src/pharo/opensmalltalk-vm$ LCALL=C > scripts/updateSCCSVersions No stash found. >

Re: [Pharo-users] stfx.eu down

by Paul DeBruicker

I wonder if there is a way to get all the relevant configs in an image to point to the smalltalkhub repo instead of the mc.stfx.eu repo temporarily. In Pharo 6.1 if a person wants to switch away from the mc.stfx.eu domain in their ConfigurationOf* and BaselineOf* specs you can right click on a package in Nautilus, choose "Rewrite code" then choose "Rewrite code" again and paste each of the below into the box and save it to rewrite the repository definition. RBParseTreeRewriter new replace: '''http://mc.stfx.eu/ZincHTTPComponents''' with: '''http://smalltalkhub.com/mc/SvenVanCaekenberghe/ZincHTTPComponents/main'''; yourself RBParseTreeRewriter new replace: '''http://mc.stfx.eu/Zodiac''' with: '''http://smalltalkhub.com/mc/SvenVanCaekenberghe/Zodiac/main'''; yourself RBParseTreeRewriter new replace: '''http://mc.stfx.eu/Neo''' with: '''http://smalltalkhub.com/mc/SvenVanCaekenberghe/Neo/main'''; yourself to "fix" Zinc, Zodiac, and Neo respectively.

Re: [Pharo-users] any ihint how to do this

by Richard O'Keefe

Having imagined collection count: [:each | ...] DO NOT IMPLEMENT IT! Check to see if it already exists. Hint: it DOES exists and has done since before Pharo. So 'pangrams are fun but this isn''t one' count: [:each | each isVowel] already answers 10. Something that may help you a lot is to visit the Collection class in the browser, and read every method in the 'enumerating' category. (You will benefit from looking at the others too, but we are staying focussed.) When you have done that, visit the SequenceableCollection class, and read every method in its 'enumerating' category. For example, you will certainly find #overlappingPairsDo:. Given that, you can add overlappingPairsAnySatisfy: testBlock self overlappingPairsDo: [:x :y | (testBlock value: x value: y) ifTrue: [^true]]. ^false And now you can test for two adjacent equal elements using aSequence oberlappingPairsAnySatisfy: [:x :y | x = y] On Tue, 11 Dec 2018 at 06:05, Richard Sargent < richard.sargent(a)gemtalksystems.com> wrote: > > > On Mon, Dec 10, 2018 at 8:52 AM Roelof Wobben <r.wobben(a)home.nl> wrote: > >> Hello, >> >> is there a way I can check if a word has 2 the same chars after each other >> I was hoping that '#groupby could help me but that one sorts >> so abba the aa is found >> or do I have to use a stream for that >> >> could I then also use that stream to check if a word contains 3 vowels ? >> > > I'll start with this question first, since it is the easiest to discuss. > The brute-force approach would be to use #select: against the word to > extract all the vowels.

stfx.eu down

by Sven Van Caekenberghe

Hi, This evening I somehow broke my stfx.eu server while doing an ubuntu dist upgrade (an old AWS EC2 machine). This means several websites / web services hosted by that machine are down, most notably mc.stfx.eu (hosting several of my packages) and ws.stfx.eu (used for shared smalltalk workspaces). A couple of Zinc tests will also fail. For source code access, all my public repos exist both in an up to date form on GitHub (http://github.com/svenvc) as well in the original form in SmalltalkHub (http://smalltalkhub.com/#!/~SvenVanCaekenberghe) or SS3. The main problem there is that the distributed ConfigurationsOf and Catalog entries will still point to the original. This is not a problem with git's BaselineOf definitions. Although the machine will no longer boot, I managed to mount the original volume on another instance so I can still access the whole filesystem. This will make it possible to eventually recover most services. But this will take time as these things never happen when it is convenient. It will give me an opportunity to modernise the setup though, which is good. Sorry for the inconvenience. Sven

The brute-force approach would be to use #select: against the word to extract all the vowels. But a better approach, would be to imagine what you need and delegate it. So, we already have #select:, #reject, #detect:, and #collect: as patterns. Imagine a new method called #count:, and implement that. (For the purpose of the assignment, implementing #count: is probably overkill, unless you have many, many words to check.) Now, back to the first question. You want to iterate through the word "pairwise", where you examine each successive pair of letters. So, you want to iterate from 1 through n-1 and check whether the letter at the index is the same as the letter at the index + 1. That should be enough to get you going. > I ask also on the discord app but no answer for a long time > > > Regards, > > Roelof > >
