Encoding CJK URL?

by Wowerat Dirk

My code to download some UTF8 text with japanese kanji from an url: url := 'http://www.hatinosu.net/onsen/import.kml' asZnUrl. url_string := url retrieveContents. url_string class. ByteString Now the japanese parts of url_string are unreadable. What I need is WidString and not ByteString. On linux I "solved" the problem with this workaround. download := 'wget -O /tmp/file.tmp "http://www.hatinosu.net/onsen/import.kml"'. OSProcess thisOSProcess waitForCommand: download. fs := FileStream fileNamed: '/tmp/file.tmp'. string := fs contents. fs close. string class. WideString How do I do this without extern programms?

Re: [Pharo-users] [ANN] JSON datatype support in PostgresV2 package

by Esteban A. Maringolo

Oh, I forgot. The datatype fields are converted to instances of JsonObject, from the PharoExtras/JSON package. So the version 2.4 loads such package. Even though I don't use PharoExtras/JSON for my daily JSON manipulation (I use Seaside-JSON and NeoJSON), I found it to be the most "modular"/"independent" JSON package out there. The fieldConverter can be replaced "live" in the PGConnection object by anything you like. Regards! Esteban A. Maringolo 2014-09-04 16:34 GMT-03:00 Esteban A.

[ANN] JSON datatype support in PostgresV2 package

by Esteban A. Maringolo

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

Re: [Pharo-users] Pharo on retina macbook

by Johan Brichau

Hi again, > This should be a known issue as it was raised before. The problem occurs with any font. It has to do with the VM as far as I understood. I am not sure what is needed to be done, though. I know this was raised when the retina display came out but I did not follow any development since I was not using one. Now, I thought it had been fixed because, surely, I must not be the only one using a retina macbook with Pharo? Anyway, I can understand if this is a known issue but is it well understood what should be done? > What version of Pharo? 30856 > What version of OSX? 10.9.4 > What fonts? Any font that I can select in Pharo actually. thanks for the links below. I will try and report results.

Cool - thatâs handy to know it works somewhere (and in fact, it was when playing with GT-Inspector I noticed this - so that solution would work). Iâm still curious how you do it in Morphic?
