[Pharo-project] who is "dfgs"?
by Pavel Krivanek Dec. 15, 2012

Dec. 15, 2012

Hi, I would like to ask who has the initials "dfgs". And I have a question for him/her. The VTermInputDriver initialization methods generate a lot of unimplemented calls because they expect a handler object with protocol that is not defined in the image. Do we need the VTerm classes at all? Can you provide an abstract handler class? Or what about to switch this calls to perform:/perform:with: form. Cheers, -- Pavel

[Pharo-project] Is the plugin JoystickTabletPlugin of the CogVM package working?
by Carla F. Griggio Dec. 15, 2012

Dec. 15, 2012

Hello! Does anybody know if the JoystickTabletPlugin is actually working for Pharo? I'm trying to use it with CogVM with no success :( I see in InputEventHandler that there is support for pen tablets using this plugin but I can't manage to make it work. As it comes in the CogVM package I assume that somebody put it there because it works, but I keep getting "PrimitiveFailed" error messages wether I have a tablet connected or not. The external plugins of the CogVM are supposed to work without me doing anything? Just executing the VM? Or do I have to activate them somehow? Sorry for keep bothering with this :$ And thanks! Carla.

[Pharo-project] Kernel-Numbers don't reference Locale decimalPoint
by Dario Trussardi Dec. 14, 2012

Dec. 14, 2012

Ciao, i'm working for manage some write - read data ( MANumberDescription / MAScaledDecimalDescription / SIXX interchange data ) about Number and is subclass. I see some codes into Kernel-Numbers and i found it don't reference the Locale decimalPoint. The codes directly define the $. when reference the decimal. Now if i have setup the Locale decimalPoint to $, the SIXX write data with $. After if i read this sixx data into another environment ( for example Gemstone ) where i setup Locale decimalPoint to $, the system can't generate right Numbers. Another problem is relative to the Number readFrom: stringOrStream "Answer a decimal number as described on stringOrStream. The number may not include a leading radix specification, as in 16rFADE, nor an exponent like 1.0e-3 It might have a scale specification at end or not like 10.3s2 If not, number of digits after decimal point will be used as scale" ^(SqNumberParser on: stringOrStream) next........... because also the SqNumberParser don't reference the Locale decimalPoint. In this case if in my application i need to use the $, as decimalPoint ( and i use it in the Seaside TextInput ) follow stringOrStream is based on $, ( for example '123,89' ) as result SqNumberParser can't generate right numbers. Before begin to do some change i'm interested to know some other think about this problematic and if someone working around it. Thanks for any consideration, Dario

[Pharo-project] Setup Locale decimalPoint for Italy
by Dario Trussardi Dec. 14, 2012

Dec. 14, 2012

Hi, i work with Pharo Pharo1.4 Latest update: #14445. i need to setup some based data: Locale decimalPoint primDigitGrouping currencySymbol DateAndTime localTimeZone for work with relative Italy data. In detail: Locale decimalPoint -> $, primDigitGrouping -> $. currencySymbol ->$â¬ The DateAndTime localTimeZone is setup to Local Time with offset of 0:01:00:00 ( i think is right relative to Rome ). Thanks for any help, Dario

FileDirectory is actually made up of 10 classes providing a rich but utilitarian API for traversal, navigation, stream creation, copying and renaming, filename parsing utilities. Platform-specific implementations all share the same API, including one for remote FTP access. For you to say "no API" is silly. > So, i really doubt that you end up with 'little disruption to API'.

You can design for 20 years but if real-world results are never harvested then it was only ever just playing around with a cool toy. My goal is to get as far along my software journey as my limited lifespan will allow.. > FileSystem establishing a clear > separation between conceptual model > ... snip ... > won't require serious changes and will serve you much much longer > without need to change anything in userland code. (Take a Collection > protocols for example). .. and so when I become faced with having to make "serious changes" in my "userland code," (e.g., a complex ODBMS system) just to hold position along my journey; naturally I'm resistant. You can try to justify it with design theory but, at the end of the day, the two frameworks do basically the same thing, converting to it is mostly pure cost. > Also, once you have such set of rules, it is much easier for people to > maintain implementation code, > as well as adding extra functionality if needed. > > Clearly, VM interfaces (such as primitives) should be not exposed to > ... Igor, a very good explanation for our individual views here is that your journey is building a great new Smalltalk, mine is something else. Cheers, Chris

Are there plans for SqueakDBX regarding porting it to Pharo 2.0 or moving it from FFI to NativeBoost?

[Pharo-project] another kid born: NBExternalEnumerationType
by Ciprian Teodorov Dec. 13, 2012

Dec. 13, 2012

Hi guys, today I have commited to the NativeBoost repository a new core class, the NBExternalEnumerationType, which reifies the enum declarations in C and offers a nice interface (especially in terms of debug/inspect). To use it just subclass the NBExternalEnumeration and add an #enumDeclmethod to the class side such as: NBExternalEnumeration subclass: #NBTestEnumeration instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'NativeBoost-Tests' NBTestEnumeration class>>enumDecl ^ {(#AAA -> 1). (#BBB -> 2). (#CCC -> 3). (#DDD -> 2400)} asDictionary DO NOT FORGET to call the #initialize method on your class. The rest is automatically done ;) You can use your new enum in two ways: - add it to a client class poolDictionaries list (see #NBExternalEnumTests for an example), and then just write CCC in your code -- CCC here is an item of your enum - or you can send the name of an item to your class --- NBTestEnumeration DDD The NBExternalEnumeration implements (instance and class) some more API methods like: - #itemAt: retrieves the item having a specific value --- NBTestEnumeration itemAt: 2 - #includes: checks the existence of a specific item in the enum --- NBTestEnumeration includes: #AAA Having this already gives us a nice interface to working with enums. Now I plan to improve a little bit on performance and usage scenarios: - the possibility to accept smalltalk integers as valid input/output for functions(or callbacks) that use enums as arguments/return. - support the different representation types for the enum values (int/uint) So that will be for now. Feel free to try it out and send me any comments and/or improvement ideas, It will be my pleasure to improve it.

by Sven Van Caekenberghe Dec. 13, 2012

Dec. 13, 2012

Just a quick note: the first version of Zinc-Resource-Meta-[Core|Tests] containing ZnUrl and ZnMimeType independent of / separate from / as a dependency for Zinc-HTTP is now available. ConfigurationOfZincHTTPComponents version 2.0 reflects this change (#stable for Pharo 2.x). -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
