[Pharo-project] 16rff broke 16r8e7

by Nicolas Cellier

As you may know, with 16rff change, we cannot anymore use a radix notation combined with an exponent notation. At least for base > 14, the exponent letter is taken as an ordinary digit. The options are: 1) revert the change 2) abandon combined radix+exponent notation all the code for printing Float with different radix, and also for scanning can be removed Or I can provide a subclass of SqNumberParser for backward compatibility. 3) find a new syntax for radix+exponent For example, 16r7f_e6 16r7f^6 16r7f#6 None of these is ambiguous with existing code. Or maybe use an uppercase R for uppercase only digits... 4) use q exponent to at least enable base 16 This is hackish and not universal, but I guess hardly anybody ever used a base > 16. ------------------------------------- What would squeak/pharo folks choose ? ------------------------------------- Personnally, I'm OK with 1) and 2). But 2) deserves a bit more discussion After all this is a change of Squeak syntax. I find Dan's notation educative and fun, especially for writing tests. But it is a non portable Squeakish thing, rarely used, and it does not really has much value for industrial usage, On the other hand, is it really necessary to parse 16rff ? I dislike 3) because I find my own propositions bad. Also, if we remove Squeak-specific syntax for compatibility reasons, why the hell adding a new uncompatible syntax? Previous usage of e notation was far better because just extending an existing syntax, not creating a new one. Maybe you'll have other ideas... Nicolas -------------------------------------

Re: [Pharo-project] HelpSystem implementation

Hi Danny, > - What is the reason to have HelpBuilder and to create a hierarchy of > HelpTopic instances mirroring the layout of the actual content classes? > Why > not use the class objects directly? HelpBuilder builds the topics/books from code. I just wanted to decouple the storage mechanism (here ST source code). Topics/books could also be stored in an external database/files or even created on the fly from dynamic information. > - Why do you use pragmas for the titles of the pages?

Did'nt like firstPage ^#{'First Page Title' 'Contents'} No other reason. Or we return a dictionary in #pages? Would this be better? Bye T. -- Sicherer, schneller und einfacher.

[Pharo-project] Issue 1884: NetNameResolver doesn't work in PharoCore

by Adrian Lienhard

http://code.google.com/p/pharo/issues/detail?id=1884 This issue probably is the last obstacle for the 1.0 release. I've added the following comment: --------- The preference proposed by Miguel does not solve the problem but puts the burden on the user that needs to change the preference depending on which implementation works for him. This will lead to many questions and frustrated users. If possible, I'd prefer to make the legacy IPv4 implementation work again until we have a proper IPv6 implementation. The problem with printing "NetNameResolver addressForName: 'www.yahoo.com'" is not that the resolution does not work correctly but that the printOn: implementation of SocketAddress assumes an IPv6 address. I suggest to change the SocketAddress>>printOn: as follows. Maybe it's just this simple change to makes IPv4 work again -- maybe more such backward compatibility code is needed. SocketAddress >>printOn: aStream NetNameResolver useOldNetwork ifTrue: [ ^ super printOn: aStream ]. aStream nextPutAll: self hostNumber; nextPut: $(; nextPutAll: self hostName; nextPut: $); nextPut: $,; nextPutAll: self serviceNumber; nextPut: $(; nextPutAll: self serviceName; nextPut: $) --------- This change makes #addressForName: work again with useOldNetwork set to true (as it is in recent PharoCore 1.0 images). Could people that experience problems with the network code update this method and check out if other parts break? Cheers, Adrian ___________________ http://www.adrian-lienhard.ch/

Incredible. Clap clap clap! Let me say that I really like your screencast and every time I see them, I learn. I think that we really should have a link from the official pharo website to your blog.

Well *cough* I've always wondered why we use a un-supported smalltalk based decoder here versus relying on the JPEGReadWriter2 which uses the JPEG libraries we bundle into the VMs. Maybe you should to a quick performance test and see how they compare?
