Bug in Regex?

by Mariano Martinez Peck

Hi guys, Look at this case: `'25' matchesRegex: '([0-9]|[1-9][0-9])' -> false` `'25' matchesRegex: '([1-9][0-9]|[0-9])' -> true` That is, ( a | b ) is not euqal to ( b | a ) " a or b is not equal to b or a" and should describe a range of 0 to 99. I don't understand why the first sentence answers false. Even Pharo 1.1 answers false (so this is very very old behavior). I checked on other dialects and it answers true. I then checked here [1] and it also find matches. So...do you see some rational explanation or sounds like a bug?

This allows support for the different file system interfaces in Cuis, Pharo and Squeak. For example, one of the compatibility methods is: OSProcess class>>directoryExists: path "Answer true if a directory of the given name exists. The given name may be either a full path name or a local directory within this directory." ^ self useFileMan ifTrue: [((Smalltalk at: #DirectoryEntry) perform: #withPathName: with: path) exists] ifFalse: [self useFileSystem ifTrue: [ (path perform: #asFileReference) exists ] ifFalse: [ (Smalltalk at: #FileDirectory) default directoryExists: path ]] And the tests for Cuis/Pharo/Squeak are in these two methods: OSProcess class>>useFileSystem "If true use FileSystem, otherwise use traditional FileDirectory. See senders for methods with file system dependencies." ^ Smalltalk hasClassNamed: #FileReference OSProcess class>>useFileMan "If true use FileMan for directory and file access. See senders for methods with file system dependencies." ^ Smalltalk hasClassNamed: #FileIOAccessor This is ugly but it does work, and I been able to maintain OSProcess and CommandShell for the Squeak diaspora over a number of years in this manner. It also means that I do not need to worry if Squeak moves to FileMan(*) or FileSystem at some point in the future. I don't think that VMMaker should have a hard dependency on OSProcess, but as a practical matter you probably have OSProcess loaded in the VM development image anyway, so you could try using these methods directly and see how ugly things get. HTH, Dave * Personally I like the FileMan approach in Cuis best, but that is another topic entirely ;-)

Re: [Pharo-dev] VMMaker in Pharo [Was: Squeak and Tonel]

by Tudor Girba

Hi, I have seen that code, and the issue I wanted to address is to have the decision about which dialect a piece of code is ran on in one single place. This should make it easier to find statically. Indeed, this will not necessarily be guaranteed to work when moving from one version of Pharo to another. But, that problem can be addressed by tracing releases in a reproducible fashion. And in the VMMaker case, the scenario is about a development environment not a production system. So, it should be reasonable to point developers to a working configuration that pairs the Pharo/Squeak version and the VMMaker version. What do you think?

With the current infrastructure, we get those sources in Git while preserving the history from the Squeaksource repo automatically. The code will be loadable from either Git or Squeaksource, but the commit repository is still the Squeaksource one. So, nothing would change from the workflow of the current committers.

This allows us to have image-based drawing logic, like BitBlt or even better, the drawing capabilities that Juan Vuletich built in Morphic 3, transparently.

A big part of it was my own emotional attachment to Squeak, my "muscle memory" with Squeak and my long experience with Smalltalk-80 derived meta programming which I make extensive use of in VMMaker.oscog. But a key issue was that I was not prepared to *move* VMMaker.oscog to Pharo; for me it is key that it can live in both places. In particular I will not risk VMMaker.oscog being stranded on Pharo as it moves away from the "image-based rendering model". This is not because I don't believe in pixel-independent rendering models, but because productivity in VMMaker depends much more than on GToolkit inspection on the key architectural feature of being completely, safely simulateable (not a real English word; but meaning capable of being simulated). As Pharo moves towards external libraries to implement its UI so the degree to which VMMaker is simulated is reduced. Thus crashes in external code cannot be handled with the same power as with errors presented within the Smalltalk environment itself, and this (as harsh experience over thirty five years has taught me) is far more important for overall productivity than having powerful tailorable inspectors. > > > > > > I therefore wanted a Tonel that could both function for Squeak's Monticello and for Pharo's Iceberg. I had modified the Tonel serialization a little to provide well-formatted support for method timestamps, which are still a key and extremely useful part of Squeak Monticello's "blame" equivalent. Until git author attribution can be imported into Squeak's Monticello (something I don't see happening) I wanted merely to be able to have a variant of Tonel, enabled for example by a class variable, and hence /not/ present in Pharo, that would allow VMMaker.oscog to use Tonel but still be functional inside Squeak. I asked Esteban and was met by a flat no. Not "OK, but this is an option only you will use", but a flat "not under any circumstance". > > > > > > So here I am joining in this thread reluctantly. I'm extremely frustrated by the state of Tonel in Squeak and between the two dialects. ClÃ©ment had moved his Scorch optimizer to Tonel/git and I tried to use Metacello and Jakob's Tonel code to at least allow me to load that code and try and push forward on Sista/Scorch. The port *does not work*. Metacello fails to load Scorch. Neither Jakob nor Fabio, after putting in some effort, were able to fix the problem, and it is well beyond me.

Seems like the url for Metacello should point right to the "repository" directory in the git repo. so ssh://git@bitbucket.somehost.be:8899/xxx/t3-pharo/repository but when I use scp to copy a file over ssh I always have to add an extra colon (:) before the path, after the domain/port combo. So maybe its ssh://git@bitbucket.somehost.be:8899:/xxx/t3-pharo/repository Sven Van Caekenberghe-2 wrote > But it is not just private, it runs on our own servers. > > Maybe MCBitbucketRepository has to be extended like the MCGitlabRepository > as Cyril suggested ... > >> On 19 Feb 2019, at 19:08, Paul DeBruicker < > pdebruic@ > > wrote: >> >> Does >> >> Metacello>>#bitbucketUser:project:commitish: path: >> >> do what you want? >> >> >> You can set your bitbucket username/password with >> >> MCBitbucketRepository siteUsername: myUsername sitePassword: myPassword >> >> Which should let you access your private repo >> >> >> >> >> >> Sven Van Caekenberghe-2 wrote >>> Hi, >>> >>> My code lives in a private bitbucket git repo, how can I use this with >>> the >>> Metacello scripting API ? >>> >>> Metacello new >>> repository: 'ssh:// >> >>> git@.somehost >> >>> :8899/xxx/t3-pharo.git'; >>> baseline: 'BetaNineT3'; >>> load: #('core' 'gb'). >>> >>> IOW, what is the correct URL ? >>> >>> Is that even possible, if not what is the alternative ? >>> >>> I created/used this repo before, using keys as authentication. >>> >>> Could one also use username/password authentication, like when deploying >>> ? >>> >>> Sven >> >> >> >> >> >> -- >> Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

But it is not just private, it runs on our own servers. Maybe MCBitbucketRepository has to be extended like the MCGitlabRepository as Cyril suggested ... > On 19 Feb 2019, at 19:08, Paul DeBruicker <pdebruic(a)gmail.com> wrote: > > Does > > Metacello>>#bitbucketUser:project:commitish: path: > > do what you want? > > > You can set your bitbucket username/password with > > MCBitbucketRepository siteUsername: myUsername sitePassword: myPassword > > Which should let you access your private repo > > > > > > Sven Van Caekenberghe-2 wrote >> Hi, >> >> My code lives in a private bitbucket git repo, how can I use this with the >> Metacello scripting API ? >> >> Metacello new >> repository: 'ssh:// > >> git@.somehost > >> :8899/xxx/t3-pharo.git'; >> baseline: 'BetaNineT3'; >> load: #('core' 'gb'). >> >> IOW, what is the correct URL ? >> >> Is that even possible, if not what is the alternative ? >> >> I created/used this repo before, using keys as authentication. >> >> Could one also use username/password authentication, like when deploying ? >> >> Sven > > > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

Re: [Pharo-dev] Question on KmGlobalDispatcher

Hello David Indeed this is a good catch. Can you open a bug entry on github? Else I will do it but this is cool to get involved that way > On 19 Feb 2019, at 17:37, David Richards <david.i.richards.iii(a)gmail.com> wrote: > > Why does the class name KmGlobalDispatcher have a small 'm'? > > Should it be more consistently named KMGlobalDispatcher, as all other classes in package: 'Keymapping-Core'? > > Object subclass: #KmGlobalDispatcher > instanceVariableNames: 'dispatcher' > classVariableNames: '' > package: 'Keymapping-Core' > > Just curious why this name seems inconsistent. I don't recall seeing an inconsistency with class name prefixes in any other package group. Is this just a mistake, or rather an opportunity to learn something interesting about how classes should be named in Pharo? As a beginner, I'm not sure which. > > Thanks > David

Does Metacello>>#bitbucketUser:project:commitish: path: do what you want? You can set your bitbucket username/password with MCBitbucketRepository siteUsername: myUsername sitePassword: myPassword Which should let you access your private repo Sven Van Caekenberghe-2 wrote > Hi, > > My code lives in a private bitbucket git repo, how can I use this with the > Metacello scripting API ? > > Metacello new > repository: 'ssh:// > git@.somehost > :8899/xxx/t3-pharo.git'; > baseline: 'BetaNineT3'; > load: #('core' 'gb'). > > IOW, what is the correct URL ? > > Is that even possible, if not what is the alternative ? > > I created/used this repo before, using keys as authentication. > > Could one also use username/password authentication, like when deploying ? > > Sven -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
