dpeq - native PSQL extended query protocol client
Hi! Couple of weeks ago I was approached with a task of writing simple microservice, and I decided to give D a chance. The problem with performance became apparent very soon, and I started to look for the cause. I tried all existing libraries, and noted pretty mature dpq2 and ddb (and it's hb-ddb fork) libs. I didn't like the first one, because I didn't want to leave vibe-d eventloop, and the second one was native (big plus for me), supported vibe-d sockets. I forked it, multiplied performance by hacking in write buffer, but then the whole philosophy behind it's code structure started to bother me, it incapsulated too much IMHO. I needed something low-level, with access to message nature of the protocol. So, here's another one, uses native PSQL EQ TCP protocol: https://github.com/Boris-Barboris/dpeq https://www.postgresql.org/docs/9.5/static/protocol.html Barely any type support, barely tested, but my little service with it's two tables actually responds to requests. It's something. Maybe something good will happen and it will find it's use, maybe someone will come and write good generic ORM\DB tool for D, and we'll have a good low-level client to hack into it as an PSQL adapter, maybe it will perish. Who knows. It will definetly go, if I won't publish it though. If anyone here has some insight on typical architectural errors wich make ORM writer's life hard, please share.
Delta - Bridge to the Delphi ecosystem
Delta is a proof of concept to enhance the D Programming Language with the Delphi ecosystem. There are 2 scenarios Delta tries to achieve: - Create your GUI using the Delphi RAD Studio and connect the events with your logic written in D. The obligatory Hello World sample: https://github.com/andre2007/delta-fmx-10-2-1/tree/master/examples/gui1 - Use non visual Delphi components in your D code. There are a lot of components available for almost every purpose. For example you would be able to use the INDY (Internet Direct) components. In the sample application, the TTimer component is used. This example also shows how to write a wrapper component in D if the component is not already available. https://github.com/andre2007/delta-fmx-10-2-1/tree/master/examples/ttimer More information how to start: https://github.com/andre2007/delta-core-10-2-1/blob/master/README.md Notes: - Although Delta is currently only a proof of concept maybe some of you can profit from it. - The proxy objects on D side (TForm, TTimer, TEdit,...) currently are written manually. Maybe in the future there could be a Delphi unit parser which automatically creates the Delphi & D source proxy objects - Everytime accessing an Delphi object on D side, a new object is created. I am currently not sure whether this concept will stay - At the moment Delta targets Windows. - At the moment the packages are not registered at code.dlang.org as the project is in an early state.
Re: GitBook about D on embedded ARM Linux
That's interesting. Might do some DIY robotics in future. I would like to create a hardware abstraction layer for the BeagleBone Black (the board I am playing around with in my spare time which is very beginner friendly and flexible w.r.t. to hardware interfaces due to a lot of "capes" https://beagleboard.org/cape which are available for it) comparable with this HAL for embedded boards in Go https://github.com/kidoman/embd. This would allow people with little "low level" programming experience to play around with D on embedded linux as well. In the beginning porting some of the C++ classes from https://github.com/derekmolloy/exploringBB/tree/master/chp06 could be a good starting point. Or does someone know another HAL implementation which could be more suitable as "template" to start with? However as always... motivation is high, time is limited. Feel free to join :)
Re: DlangIDE v0.7.60 released

Project link: https://github.com/buggins/dlangide Release: https://github.com/buggins/dlangide/releases Good work! I think DlangIde should gain support from D foundation, to become a future part of the distribution like DUB. So in the end there might be one package (with batteries included :-)) to get started with D, with just one download. My suggestion is to place a special D Foundation donate button for several highly useful projects to collect money and attract more resources to improve them faster. Regards mt.
