NeoCSVReader skipEmptyLines?
by Esteban A. Maringolo Oct. 6, 2014

Oct. 6, 2014

Sven, Is it possible to skip blank/empty lines in NeoCSVReader? So if a line is empty or contains ",,,,,,,," it would be skipped from the iteration. Does it already provider such feature? (I couldn't find any setting related with this). Esteban A. Maringolo

Android VM update
by Jean Baptiste Arnaud Oct. 6, 2014

Oct. 6, 2014

Hi, I just comeback from holiday, and I realise that I do not have done a announcement yet. Now the prototype of the Pharo Android VM work. - Event is managed - Resolution up to 1080p is managed. - Most of the plugins seems worked. - File plugin allow you to browse the sd card. Next: - fix the generator then jenkins. Merge with Pharo/Cog main and Make it available for the public. - die under the mountain of bug entry open by the first public release. First release will be perfect and bugless. - allow easy personalisation of the packaging, allow you to rename and change icon easily (for your own application, Squeak/Pharo Android VM, Phratch, DR geo, etc.). - refined the jumpout logic for have a better graphical update and a better idle process (less consumption, faster reactive UI, UI updating during heavy computation, etc. ). - package the android feature in the android plugin, show/hide the keyboard via primitive, etc. etc. + init configuration. - a lot of cool idea but later Here is a youtube video to show the result: http://youtu.be/lB9UV9Z7Kss You can forward this to other mailing list, I do not have access to all of them. Best Regards Dr Arnaud jbaptiste.arnaud(a)gmail.com

Pharo Glorp 1.7 <-> VisualWorks
by FranÃ§ois Stephany Oct. 3, 2014

Oct. 3, 2014

We are tempted to give Glorp a try. We've loaded version 1.7 from the configuration browser and the simple things we've tested so far seem to work fine with the PostgresV2 driver. What is the relation between the glorp we have with the VW version? Are the two merged often? Unfortunately, we don't have the manpower to maintain such a beast, are there many people using glorp in production? With PostgresV2? Do you use all the niceties (e.g., json type) from PostgreSQL? Cheers, Francois

[ANN] JSON datatype support in PostgresV2 package
by Esteban A. Maringolo Oct. 3, 2014

Oct. 3, 2014

Spurred by the last discussion about GLORP, Postgres and friends, I spent the last few hours looking into the workings of PostgresV2 to add support to the native JSON datatype provided by PostgreSQL 9.2. According to PostgreSQL docs [1]: "The json data type can be used to store JSON (JavaScript Object Notation) data, as specified in RFC 4627. Such data can also be stored as text, but the json data type has the advantage of checking that each stored value is a valid JSON value. There are also related support functions available; see Section 9.15." It is available at ConfigurationOfPostgresV2-EstebanMaringolo.12 in SmalltalkHub, blessed as #development (v2.4). It includes a testcase for the field converter (if the database server supports it). JSON datatype allows the indexing and querying of data inside the structure of the json object. Eg: SELECT jsonField->'attribute1'->'attribute2' FROM sampleTable; Adding support of this to GLORP should be easy, but I have no time now :) DISCLAIMER: I'm not using this in production, I tested it and seems to work as expected, and fail nosiliy when it should. This is why I blesed it as #development. If anybody is bold enough, bless it as #stable :) Best regards, Esteban A. Maringolo [1] http://www.postgresql.org/docs/9.2/static/datatype-json.html

And I wondered why SqueakDBX decided to use V2 instead of V3, a protocol introduced in 2003 or so. Stephan

PostgresV3-Core/Pool looks perfectly usable. There is PG3Connection>>md5HashMessage: aString ^Smalltalk globals at: #MD5 ifPresent: [ :md5 | (md5 hashMessage: aString) hex asLowercase ] ifAbsent: [ WebUtils md5Digest: aString ] Which works in Pharo 4, though WebUtils doesn't exist anymore. Replacing it is trivial md5HashMessage: aString ^Smalltalk globals at: #MD5 ifPresent: [ :md5 | (md5 hashMessage: aString) hex asLowercase ] ifAbsent: [ (Smalltalk globals at: #WebUtils) md5Digest: aString ] Stephan

That combines well with FOSDEM, which is the next two days in Bruxelles. Yesterday I got a mail that we'll be having a smalltalk room on Sunday. Stephan
