[Pharo-project] Do we need the URI Package?
by Marcus Denker Dec. 12, 2011

Dec. 12, 2011

Hi, There are three packages concerned with URLs: -> ZnUrl in Zinc -> Network-URI -> Network-Url URI was a package from Impara that was used extensively in all Impara products and Sophie... back than, the idea was to integrate Impara infrastructure in Squeak, but that did not happen due to politics... Network-URI seems to be used nowhere in the system, so I guess we can remove it? Or is anyone using it? Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] [ANN] Eclipse Icons for Pharo
by Esteban Lorenzano Dec. 12, 2011

Dec. 12, 2011

Hi, Today I was bored and not wanting to think too much... but I wanted to do something for Pharo... and I never liked the current Pharo icons, so I took one icon library I really like and changed all needed icons (well... all that I saw). Here a couple of screen shots: Of course, I don't think they are perfect (also maybe I didn't pick the best icons), but I think they look a lot better than the older. If you want to see how they look, this are the packages: for Pharo 1.3: for Pharo 1.4: Then you execute: ThemeIcons initializeIcons. World resetWorldMenu. ... and enjoy your new icons :) btw... this icons are in an open-source license, the EPL: http://www.eclipse.org/legal/epl-v10.html so, maybe âif all agreeâ, we can add this icons to regular distribution :) best, Esteban

Done, committed more enhancements and examples (from http://cairographics.org/samples/) I'm glad to take part of the "Form" liberation front!

Are any of the stream settings wrong? Can u please share briefly how i could debug hereâ¦ What is the walkback ? > Also do i need to set the certificateName on the client stream's sslSession? > > ss := ZdcSecureSocketStream > openConnectionToHostNamed: 'localhost' port: 443. > ss sslSession certificateName: '/home/khurd/pharo/cacert.pem'. Each secure stream has an SSLSession instance on which you should set the certificate once. The argument should be the full path to the .pem file which must include both the certificate and the private key. In the document that you used I think it should be key-cert.pem, the combined private key and certificate. Good luck and be sure to let me know how it goes. Sven PS: BTW I guess you are on Linux ? Because on Mac OS X this won't work due to missing functionality in the plugin.

[Pharo-project] native boost is the best thing since COGVM

I was able to create the binding to Pango using NB. The ultimate goal is to provide a cleaner implementation of "text" widgets. Thanks Igor ! Fernando

[Pharo-project] NBCairo
by Fernando Olivero Dec. 11, 2011

Dec. 11, 2011

Hi, Javier i've enhanced a bit the NBCairo bindings. Made the examples work with FS and directly display on the Display, without creating an ImageMorph, and also release the png's. I've changed the protocol of NBCairo, and updated it to subclass NBExternalLibrary, now present in NB. I've attached the monticello packages, let me know what do you think. Fernando pd: almost have the pango bindings working, screenshots soon.

[Pharo-project] Pharo 1.3 vs 1.2.1 some results for ConfigurationOfODBC
by Ben Coman Dec. 11, 2011

Dec. 11, 2011

I have a Microsoft Access database on Microsoft Windows that I want to process using Pharo. ConfigurationOfODBC looked promising so followed instructions at http://www.pharocasts.com/2010/12/access-database-through-odbc.html, though using a blank MDB file rather than SQLLite, and 'TestMDB' as the ODBC DSN, I executed... --8<--- Gofer new squeaksource: 'ODBC'; package: 'ConfigurationOfODBC'; load. (Smalltalk at: #ConfigurationOfODBC) load. connection := ODBCConnection dsn: 'TestMDB' user: '' password: ''. connection execute: 'CREATE TABLE user(name varchar(10), age smallint)'. connection execute: 'INSERT INTO user VALUES(''Old Bob'', 100)'. contents := (connection query: 'select * from user;') execute: ''. contents asTable inspect. connection close. --8<--- which failed on Pharo 1.3 but worked on Pharo 1.2.1. To debug this I compared each by single stepping 1.3 & 1.2.1 side-by-side. I executed... connection := ODBCConnection dsn: 'TestMDB' user: '' password: ''. which seemed to worked the same on both platforms up to the inserted 'self halt' shown here... --8<--- ODBCConnection>>connect "Connect to the database" self registerForFinalization. hEnv := self sqlAllocEnv. false ifTrue: [ self sqlSetEnvAttr: 200 value: 2 "SQL_ATTR_ODBC_VERSION" ]. self halt. hdbc := self sqlAllocConnect: hEnv. --8<--- ODBCConnection>>sqlAllocConnect: envHandle | h | h := SQLHDBC new. self checkSQLReturn: (ODBCLibrary default sqlAllocConnectEnvironment: hEnv connection: h ). ^h --8<--- ODBCLibrary(Object)>>sqlAllocConnectEnvironment: environmentHandle connection: connectionHandle "SQLRETURN SQLAllocConnect( SQLHENV EnvironmentHandle, SQLHDBC *ConnectionHandle);" <cdecl: short 'SQLAllocConnect' (SQLHENV SQLHDBC*)> ^ self externalCallFailed --8<--- ODBCConnection>>checkSQLReturn: sqlReturn "private - check the sqlReturn and generates an exception if corresponds" self checkSQLReturn: sqlReturn environment: hEnv connection: hdbc statement: nil --8<--- If you've followed the call chain down to here, then the result is...
