Zink geo location data reading

by bachitoph

Hi, I'm playing around with Zink reading the geo location of any IP-address. Evaluating the code below in a playground works fine. But what is the best way to read the entity data of the ZnResponse instance I get back. Have I to parse it, with an self written parser, or is there anything available. |client znResponse location| client := ZnClient new. client host: 'www.geoplugin.net'. client addPathSegment: 'php.gp'. client queryAt: 'ip' put: '188.194.228.195'. znResponse := client get; response. The code should anyhow look like this. AnyParser parse: (ReadStream on: znResponse contents). In PHP the example code is at http://www.geoplugin.com/webservices/php var_export(unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip=188.194.228.195] I'm searching for the unserialize of the php, which delivers an array with key value pairs. The response entity contents looks somehow like the bottom string without the newlines. 'a:18:{ s:17:"geoplugin_request";s:15:"188.194.228.195"; s:16:"geoplugin_status";i:200; s:16:"geoplugin_credit";s:145:"Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com <\'http://www.maxmind.com\'> ."; s:14:"geoplugin_city";s:6:"Passau"; s:16:"geoplugin_region";s:7:"Bavaria"; s:18:"geoplugin_areaCode";s:1:"0"; s:17:"geoplugin_dmaCode";s:1:"0"; s:21:"geoplugin_countryCode";s:2:"DE"; s:21:"geoplugin_countryName";s:7:"Germany"; s:23:"geoplugin_continentCode";s:2:"EU"; s:18:"geoplugin_latitude";s:7:"48.5833"; s:19:"geoplugin_longitude";s:7:"13.4833"; s:20:"geoplugin_regionCode";s:2:"02"; s:20:"geoplugin_regionName";s:7:"Bavaria"; s:22:"geoplugin_currencyCode";s:3:"EUR"; s:24:"geoplugin_currencySymbol";s:7:"€"; s:29:"geoplugin_currencySymbol_UTF8";s:3:"â¬"; s:27:"geoplugin_currencyConverter";s:6:"0.9348";}' Thanks for any help cjb -- View this message in context: http://forum.world.st/Zink-geo-location-data-reading-tp4951446.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Porting Transducers to Pharo

by Steffen MÃ¤rcker

Hi Phil, > Tell me how it goes for you. I played a bit with Iceberg in Pharo, managed to check out the repository, and load Transducers-Core. As a bit of a surprise, multiple packages show up in the SystemBrowser; one for each method category, e.g., Transducers-accessing and Transducers-class initialization. Is this expected? Maybe I am just missing something obvious here since I am not familiar with the tools. However, I think Iceberg will facilitate a nice way exchange code between VW an Pharo. I managed to export the packages using STIG from VW and the differences seem to be sufficiently small. > I've put a README. md with your notes, and under packages/ you'll find 3 > packages: > > Transducers-Core > Transducers-Examples > Transducers-Tests Did you rename the main package from Transducers to Transducers-Core for a special reason?

Re: [Pharo-users] vested interest in PharoJS?

by Dimitris Chloupis

from my extremely limited understanding about web dev, Seaside if my memory serves me correctly it integrate JS/ HTML/ CSS . IT has many great features, its mature and well documented. Most likely most existing pharo web dev frameworks do this as well. PharoJS is definitely a very cool idea, but its a big project none the less , so it will take some time for it to get there. Assuming devs contribute to it, the massive difference between "I want" and "I make".
