It would be very good to have another Glorp solution with a pure Smalltalk implemented DB driver, like the PostgresV2 one. IMHO this is way less error prone than the whole library/driver/.. mess on all these different platform. Sven

I have similar plans and also want to use MySQL under Windows. Olivier points me to ODBC connector (http://smalltalkhub.com/#!/~PharoExtras/ODBC <http://smalltalkhub.com/#%21/%7EPharoExtras/ODBC>). Merwan points me to a MySQL driver (http://smalltalkhub.com/#!/~DBXTalk/MysqlDriver) Anyway: Can someone tell me, if DBXtalk is the way to go?

Re: [Pharo-users] How to silently generate and remove code

Before that I would like that the compiler outputs classes definition in an environment (that can be the default one) but that can be the one I want and specified from the outside of the compiler.

Normally you can use versionString: Le 29/3/15 05:20, Pierce Ng a Ã©crit : > I've put up code for JSON-RPC (server only for now, tested with some Python > client) on SS3.

Writing ConfigurationOf depending on beyond bleeding edge code

by Pierce Ng

I've put up code for JSON-RPC (server only for now, tested with some Python client) on SS3. The code uses Sven's excellent Zinc and NeoJSON libraries. I'm now writing a ConfigurationOf. The current release of NeoJSON, going by its ConfigurationOf, has Neo-JSON-Core-Sven.27. However, I am using Neo-JSON-Core-Sven.29, which has NeoJSONWriter>>writeNil: required by the JSON-RPC spec. How should I express this dependency in JSON-RPC's ConfigurationOf? At present it looks like this (monkey-see monkey-do using some other configuration): spec project: 'NeoJSON' with: [ spec className: 'ConfigurationOfNeoJSON'; loads: #('Core'); repository: ... ] Thanks. Maybe if Sven reads this he can mark .29 as the stable release. That'll work too. :-) Pierce

Not sure whether it has been moved to SS3 or STH. http://www.squeaksource.com/StdbMysqlProtocol Others have suggested Glorp. Glancing at the code, seems Glorp currently only works with VisualWorks' MySQL driver. Based on my experience integrating NBSQLite3 into Glorp, I'd say it will take about a day or two, depending on the design of the driver. I've tested abovementioned MySQL driver with some version of MySQL5 some months ago. Pierce
