And this will not change. I think there is no way that we can work constructively together, so the best for all is that you just go away. and everyone is happy. (you, too!)

I think the reasoning for you should be trivial: Pharo is not good enough for you. You don't intent to help fixing that, you just want to show off how great you are by showing the (imagined) faults in others. Please unsubscribe from the mailinglist.

I dont fully understand your question, also i have no idea what #gsub does. do you start from a dictionary ? or a string ? it seems that you want to create a dictionary from a particular string. Could you provide an example of such string, i could help you in finding the correct messages of String/Stream to send. The #gsub message, seems pertinent to all Strings? or is a special behavior for your special case?

[Pharo-project] Comparing a package code with current code
by Hernan Wilkinson Nov. 14, 2011

Nov. 14, 2011

Hi, I wanted to migrate TDDFacilities to make it work with Pharo 1.3, but I could not find a way to compare the code that is changed in TDDFacilities from Pharo-Core and others with the code that comes with Pharo 1.3, so it is very dificult to find the changes I have to merge, change, etc... How can I see the differences between code that is in a package and the code in an image?

[Pharo-project] [Progress Report] Zinc HTTP Components
by Sven Van Caekenberghe Nov. 14, 2011

Nov. 14, 2011

Hi, This is a list of the most important changes to Zn since May 1st 2011: - added brand new ZnClient to replace all other HTTP clients (who became deprecated) this is an object to build, execute and process HTTP client requests, it has a rich protocol to construct requests and to access responses, it has various error handling options, it can reuse an existing connection to a specific host:port, it can handle sessions, cookies, redirects and authentication, it has many options (settings) with sensible defaults. here is the simplest example: ZnClient new get: 'http://zn.stfx.eu/zn/numbers.txt' and here is an example using some features to make a better HTTP request: ZnClient new systemPolicy; accept: ZnMimeType textPlain; http; host: 'zn.stfx.eu'; path: 'zn/numbers.txt'; contentReader: [ :entity | entity contents lines collect: [ :each | each asNumber ] ]; ifFail: [ :exception | self inform: 'I am sorry: ', exception printString ]; get - added support so that HTTPS works out of the box if Zodiac is present. this should work when Zodiac is loaded and the necessary plugin is present: ZnClient new url: 'https://www.google.com/search'; queryAt: 'q' put: 'Pharo Smalltalk'; get - added a new subclass, ZnManagingMultiThreadedServer, that keeps track of open worker connections so that they can be properly closed when needed. to use this server with the Zn Seaside adaptor, you can do this: ZnZincServerAdaptor new port: 8080; serverClass: ZnManagingMultiThreadedServer; start - refactored ZnNetworkingUtils, it is now (also) a factory for creating socket streams - added ZnDispatcherDelegate for straight-forward dispatching to mapped urls (thx Nick Ager) - cleanup of the cookie handling API - fixed support for HTTP proxies (thx Alexandre Bergel for reporting) - localhost URLs are now excluded from being proxied - working around SocketStream>>#atEnd issues by using #peek - implemented support for proxies that require authorization - introduced ZnConnectionTimeout process variable - added ManagedServers class variable to ZnServer to dispatch the system's #startUp/#shutDown messages to all server instances that are #register-ed - implemented client side support for If-Modified-Since and Not Modified - changed ZnMimePart>>#fieldValueString to return an empty string instead of 'nil' when the field is empty or absent (Thx Lukas Renggli) - added support for dealing with certain defaults in ZnUrl - added code to throw a ZnMissingHost exception when a bogus ZnUrl is used to connect to a HTTP host - added ZnMimeType wildcard constants #any and #text - added ZnHttpUnsuccessful and ZnUnexpectedContentType exceptions - added a nice example to ZnEasy class>>#getPng: (Thx Lukas Renggli) - added ZnUtils class>>#parseHttpDate: for use in ZnCookie>>#expiresTimeStamp - added optional delegate #close-ing to ZnServer hierarchy - added some Pharo 1.2 compatibility (ZnMultiThreadedServer>>#exceptionSet:) - lots of small fixes, cleanup and improved documentation Sven

[Pharo-project] gsub like solution for Pharo/Smalltalk
by mail list Nov. 14, 2011

Nov. 14, 2011

I have a dictionary of keys and values. I have a text string in which the keys are marked with before and ending symbols. In ruby to replace the key with the value in the text string is reasonably simple. (eg Dictionary.each { key,value | string.gsub!(key,value) } - or similar to this. While I don't mind rolling my version of this in Smalltalk, just exploring the regex code and the streams code it is not obvious where is the easiest place to start. If someone would put their comments on where to start I will build the functionality and put it up on squeaksource since I think it is common requirement. S.
