How do I
by Friedrich Dominicus Nov. 21, 2014

Nov. 21, 2014

get the red color from the editor if aa methods gets really long. Eg I have an initialization of a dictionary with 50 or so elements and have put them into one method of course it's getting very red. Anyway it's just something like this add: Element add: anotherElement .... So no program logic at all just one element added after the other. I found I can still lint with a pragma, but still the editor is "red" That really gets on my nerves. So what can I do to stop this "reddening"? Regards Friedrich

[ANN] Hubcap - a SmalltalkHub API and browser for Pharo
by Torsten Bergmann Nov. 21, 2014

Nov. 21, 2014

Hi, as I wanted to browse the SmalltalkHub contents directly from within Pharo image I wrote a simple browser: Gofer it url: 'http://www.smalltalkhub.com/mc/TorstenBergmann/Hubcap/main'; configurationOf: 'Hubcap'; loadDevelopment. Attached is a screenshot. Works on Pharo 4.0. Still not finished but maybe it is already useful to others as well. One can access the tool from the world menu, implementation lives in "Hubcap-Tools" package. The UI shows and allows to filter users, shows their projects and packages. Special icons display the state (loaded, modified, public writable, ...). One can load from the UI or open Monticello tools. The "Hubcap-Core" package includes an API to query STHub and write expressions like: HubClient new allProjectsForUserNamed: 'TorstenBergmann' HubClient new hasUserNamed: 'TorstenBergmann' So "Hubcap-Core" may be usefull to people who want to build other tools that depend on STHub infos. Basic documentation lives on http://www.smalltalkhub.com/#!/~TorstenBergmann/Hubcap and as class comment on ConfigurationOfHubcap. Beware: the tool is sill not optimized, any clicking involves a query to STHub (hope STHub will not crash when many people use it). API may still undergo changes in the future. Also teams are not yet supported as STHub still returns an MNU error in the REST interface: http://www.smalltalkhub.com/hub/teams?term=Pharo Anyone able to fix that? Thanks to Stephan Eggermonts who gave me the initial idea with some code I've found in "Deprecation finder" and to Sven for the easy to use NeoJSON package. Contributors can just commit, the project is public. Bye T.

Hi! Pierre just finished a first version of Kiviat in Roassal. Here are some example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= b := RTKiviatBuilder new. b objects: RTAbstractCircleLayout withAllSubclasses. n := RTMultiLinearColorForIdentity new objects: (b objects). b shape circle color: [ :value | n rtValue: value named]; size: 10. b addMetric: #numberOfLinesOfCode. b addMetric: #numberOfMethods. b addMetric: #numberOfVariables. b activatePolygons. b build. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= It would be great to have feedback on this!

Pharo and ODBC
by olivier auverlot Nov. 20, 2014

Nov. 20, 2014

Hi, I try to use the ODBC framework presents in the configurations list and named "ODBC (TorstenBergmann.5)" I want connect Pharo to a Postgresql server and I installed the latest version of the ODBC driver. The datasource is configured as system datasource. The connection test is ok. My computer uses Windows 7 64 bits. In Pharo, I try to connect with the following code: connection := ODBCConnection dsn: 'mysource' user: 'myuser' password: 'mypassword'. connection close. The connection fails and I get an error message: "The data source (DSN) has a specified architecture incompatibility between the driver and the application". Someone have an idea about this problem ? Someone works with the ODBC solution ? Best regards Olivier

Building 64-bit pharo VM
by Evan Donahue Nov. 19, 2014

Nov. 19, 2014

Hello, I am working on building a 64-bit pharo vm to open large files, as per a previous question to the list. I have gone down a few roads from different dates and with different basic strategies and met with little success so far. Could someone recommend the best place to look for the vm build instructions that would be the closest fit to building a current pharo vm for pharo4 in 64 bits on a 64 bit arch linux os? Thanks, Evan

Combining multiple booleans in one word still helps a lot, and introducing extra objects for highly correlated fields. >The key I mentioned here is that in real life, this "normalizing ratio" >is very high for almost every kind of data and that's what puzzles me >(not the technique). My impression is that the a lot of the design decisions for relational databases are cargo cult based on the time where most database did not fit into ram and the query optimizers were not good at dealing with lots of joins.
