Re: [Pharo-users] [Glass] How do you develop for gemstone in open source tools (pharo)?

by Tudor Girba

Hi, gt4gemstone is indeed a new project. The initial target of gt4gemstone is actually to support scenario 3). In this situation, even if you develop in Pharo, once you deploy your application you still want to be able to inspect/debug GemStone. In this situation, you want to have the same experience as you do in Pharo, including the extensions to the tools. Indeed, the project also contains an initial code browser (including senders/implementors) and its first target to support quick code modifications. Of course, that browser can evolve and this can lead to a full fledged experience of completely developing remotely from Pharo to GemStone. Calypso is indeed a very interesting project, but at the moment it is Pharo specific. One thing Andrei did in gt4gemstone is serialize the Glamour presentations and browsers. This is quite powerful and fast and adds another argument to the idea that browsers should be built mostly declarative. One direction we brainstormed about with Denis is to learn from the experience of both gt4gemstone and Calypso and find a common ground. But, this is future work.

Nice scenario, latest modern dev tools (browsers, inspectors, versioning) from Pharo, but on the dev side in Pharo, no transaction logic (test transaction logic with junit impossible/not available etc.), also not compatible class library - so also with drawbacks with different Smalltalk implementation chaos :( > I would very much like to get involved with Gemstone dev, but it scratches a bit now. > > > Hi Hi Petr, > > I personally do 3). I like developing on Pharo and keep doing that on each latest stable release. And yeah, you must have some compatibility layers, you must keep a ConfigurationOf working on both platforms, different class libraries (files, etc), etc. This takes time at the beginning, but then it gets easier and easier. I still use tODE for evaluating code (workspace), browsing GemStone specific code (browser), debug (stored continuations), and for developing the GemStone specific code. > > > 4) > > I think you made a good summary. In all those cases, you still consider GemStone like both things, the language interpreter PLUS the persistency. There is one last approach which uses GemStone mostly only for "persistence". In this scenario you would use GemStone similarly to what you do with a normal relational DB, that is, you open a connection, then do something.

Write the Oracle set-oriented driver according to UDBC convention. Then, write a Glorp ORM driver based on it. The Pharo version of Glorp already has OraclePlatform, which comes from the VW upstream and presumably works, so it can be used as a reference. There's also Garage which also suppors Glorp. All are available in the Catalogue Browser. STH search shows a project named Garage-Oracle by CraigAllen but 'the page does not exist, sadly.' Pierce

Pharo doesn't support C++ directly because of issues with name mangling. For C++ you need something like SWIG. See Ronie's insightful comments here... http://forum.world.st/SWIG-for-Native-Boost-FFI-td4738511.html However OCILIB describes itself as "written in pure ISO C99 code" which is much better for us.

I like developing on Pharo and keep doing that on each latest stable release. And yeah, you must have some compatibility layers, you must keep a ConfigurationOf working on both platforms, different class libraries (files, etc), etc. This takes time at the beginning, but then it gets easier and easier. I still use tODE for evaluating code (workspace), browsing GemStone specific code (browser), debug (stored continuations), and for developing the GemStone specific code. 4) I think you made a good summary. In all those cases, you still consider GemStone like both things, the language interpreter PLUS the persistency. There is one last approach which uses GemStone mostly only for "persistence". In this scenario you would use GemStone similarly to what you do with a normal relational DB, that is, you open a connection, then do something. Dale went a bit further and developed a simple Voyage kind of API with this idea in mind. Anyway, below are some interesting links.

Ideas for TechTalks wanted

by Marcus Denker

Hi! We need to setup the dates and topics for the next tech talks, they are always the last tuesday of the month. We have two kinds: -> presentation of a demo with youtube live, then Q&A (one person talks) -> More open discussion just on Discord with Audio Chat about a topic (one person started and guides a discussion) We need topic ideas and people who take the lead role for the second part of the year (August to December).

Re: [Pharo-users] How do you develop for gemstone in open source tools (pharo)?

by itlists＠schrievkrom.de

Hello, several ways to do programming under Gemstone. I personally use Jade (under Linux using WINE) the whole time. No support for git, but following the traditional browser concept of Smalltalk. Still missing some development point and has limitation - but for the traditional developer a fast lane into Gemstone/S Marten Am 22.06.2017 um 23:16 schrieb Petr Fischer: > Hello, I'm curious how _comfortably_ develop software for Gemstone, which is the preferred/best way (and future)? > > 1) tODE - OK, a decent amount of work was inserted to it to make it work somehow.

How do you develop for gemstone in open source tools (pharo)?

by Petr Fischer

Hello, I'm curious how _comfortably_ develop software for Gemstone, which is the preferred/best way (and future)? 1) tODE - OK, a decent amount of work was inserted to it to make it work somehow. Decent tools with git support, a lot of windows (autolayouting required), very basic inspector, based on obsolete Pharo3, no autocomplete, weird auto code formating etc. :( Will the development continue (better inspectors, autocomplete, etc)? 2) gt4gemstone - new project based on GT tools, great playground/workspace/inspectors, running in latest Pharo, but again, just basic browser, no autocompletion, no syntax coloring (so far), but modern way What is the plan? Write proper class browser and code editor again from scratch? There is amazing new browser for Pharo, Calypso, which has remote browsing capabilities (but probably different remoting/proxy layer than gt tools) - is possible to utilize this project for remote Gemstone browsing in future? 3) develop in Pharo, then deploy to Gemstone With some compatibility layers, there is possibility to develop application/business logic in Pharo (with bare collections, dicts, containers etc.) and then deploy code to Gemstone and test. Nice scenario, latest modern dev tools (browsers, inspectors, versioning) from Pharo, but on the dev side in Pharo, no transaction logic (test transaction logic with junit impossible/not available etc.), also not compatible class library - so also with drawbacks with different Smalltalk implementation chaos :( I would very much like to get involved with Gemstone dev, but it scratches a bit now. Thanks! pf
