17348 Enhance shortcut learnability
by Nicolai Hess Jan. 23, 2016

Jan. 23, 2016

Can please someone translate / change the text in the Shortcut reminder Morph settings.( that got integrated in 50521) see my comment on https://pharo.fogbugz.com/f/cases/17348/Enhance-shortcut-learnability#BugEv… and I asked for resubmitting the changes with proper author initials instead of "tr" and if he signed the license agreement. Anyone knows more about "tr" ? And I am not sure if the right version is integrated. nicolai

CasInsensitiveOrder map with upper/lower case characters for all latin1 entries
by Nicolai Hess Jan. 23, 2016

Jan. 23, 2016

see issues 17302/17242/17227 String>>findString:startindAt:caseSensitive appears to be failing for extended charsets String>>compare:caseSensitive seems to be failing for extended charset comparisons String>>beginsWithEmpty:caseSensitive: has test failure for some cases the problem is, the standard character set used for building the CaseInsensitiveOrder map only maps characters from the set of ascii characters but it is used in the findString/compare/beginsWith-methods for all byte characters. Any objections if we fill this map like it is suggested in case 17242 ? CaseInsensitiveOrder := AsciiOrder copy. (0 to: 255) do:[ :v | | char upper | char := v asCharacter. upper := char asUppercase. upper isOctetCharacter ifFalse: [ upper := char ]. CaseInsensitiveOrder at: char asciiValue + 1 put: (CaseInsensitiveOrder at: upper asciiValue + 1) ]. (the check for #isOctectCharacter is needed because for some entries the correspondending uppercase character is not within this character set). This would solve all three issues. nicolai

Re: [Pharo-dev] running Hapao on the String class - error: key not found in MethodDictionary for testClassComment
by sheridan＠sheridan-mahoney.com Jan. 22, 2016

Jan. 22, 2016

Hi Alejandro and Alexandro, Just wanted to let you know Hapao is working fine for me now...thanks for the help. Cheers, Sheridan Hi again! So I looked at the problem, wrote a fix, committed, created a new version and tested it. It should work out of the box :) Also the ConfigurationOfSpy should load Roassal by its own, so to download Hapao just run: ?? Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Spy2'; configurationOf: 'Spy2'; loadStable. ?? Cheers! Alejandro > On Jan 19, 2016, at 4:25 PM, Alejandro Infante > <alejandroinfante91(a)gmail.com> wrote: Hi, So this is not problem of Spy2, but a bug of Hapao. There should be no problem instrumenting String with Spy2 if your profiler is correct, the proof of this is that the image does not explode when you were debugging the execution (I was actually able to open a browser and check the tests of String). This problem happened because we naively assumed, at least in this implementation Hapao, that for every Test Object there is a Test Method associated in the class of the Test Object. This is not correct for inherited tests, where the Test Method is in one of the superclasses. I will submit a fix for that as soon as possible ;) Thanks for the bug report!!

To begin, I loaded Spy2 and Roassal2 using the following code: Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load. Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Spy2'; configurationOf: 'Spy2'; loadStable. Hapao then showed up in the "World" menu, and I selected it. I chose "Hapao @ class ... " and entered "String". Hapao starts running tests, but before long a debugger comes up with the error: KeyNotFound: key #testClassComment not found in MethodDictionary . IF I click "Proceed", other keyNotFound errors come up. This is in a 50524 image. Is there something wrong with the way I am invoking Hapao? Many thanks, Sheridan

Plug for Damien and Cyril) For a list of changes in this release, follow this link: https://github.com/Balletie/GitHub/releases/tag/v0.5 <https://github.com/Balletie/GitHub/releases/tag/v0.5> To load absolutely everything, including the tests and the tool, evaluate: Metacello new baseline: 'GitHub'; repository: 'github://Balletie/GitHub:master'; load: #(tests tool) If you have loaded the tool, it can be opened via the world menu, under âToolsâ. Feedback welcome :)

Currently, the image is the result of an evolutionary process and rebuilding it from zero was not possible. This maes it possible to audit the whole build process, create different base image for various purposes (very small, headless with no UI objects at all, using the object engine in a completely different way that is used today). That makes the image the result of a fully reproducible process, from a file of zero bytes, to a file with a working image. That would make us master the whole chain. Today, there is still black magic in the image, due to the history. That's an exciting development. For example, in C, one compiles all files, and links, giving the exe. All that from a file of zero size. We will be able to do the same kind of thing at the image level. Also, this allows to experiment with new low level mechanisms. This is currently not possible since it makes us like performing surgery on our own brain. Also, the Oz-inspired system will help in exploring other image memories (small or large) and manipulate them as entities. At this point, this is also not common pratice.
