OpenBSD LDC package
Hello D Community -- I'm happy to announce that I have posted a preliminary LDC package for review to OpenBSD: https://marc.info/?l=openbsd-ports=163477542025020=2 With the already shipping GDC and DMD packages, all 3 D compilers are now easily available to OpenBSD users. ~Brian

Unfortunately, the timing of DMD 2.098.0 just missed the deadline to be included in OpenBSD 7.0.

hunt-grpc 0.1.1 released! (Google gRPC for D)
Google gRPC is A high performance, open-source universal RPC
framework.
You can find it here:
https://grpc.io/
hunt-grpc is a GRPC framework developed in D language. The new
version mainly supports two-way communication and fixes some
known errors.
Example for server:
```D
import helloworld.helloworld;
import helloworld.helloworldrpc;
import grpc;
class GreeterImpl : GreeterBase
{
override Status SayHello(HelloRequest request , ref
HelloReply reply)
{
reply.message = "hello " ~ request.name;
return Status.OK;
}
}
string host = "0.0.0.0";
ushort port = 50051;
Server server = new Server();
server.listen(host , port);
server.register( new GreeterImpl());
server.start();
```
Example for client:
```D
import helloworld.helloworld;
import helloworld.helloworldrpc;
import grpc;
import std.stdio;
auto channel = new Channel("127.0.0.1" , 50051);
GreeterClient client = new GreeterClient(channel);
HelloRequest request = new HelloRequest();
HelloReply reply = new HelloReply();
request.name = "test";
auto status = client.SayHello(request , reply);
if(status.ok())
{
writeln(reply.message);
}
```
Example for streaming:

hunt entity v2.1.0 released!
Hunt Entity is an object-relational mapping (ORM) framework for
dlang's database, support PostgreSQL / MySQL / SQLite.
This version added pagination for EQL's createQuery();
Example 1 for pagination:
```D
class User
{
mixin MakeModel;
@AutoIncrement
@PrimaryKey
int id;
string name;
}
auto query = em.createQuery!User("SELECT * FROM User", new
Pageable(0, 10));
auto page = query.getPageResult();
logDebug("Page NO: %s, size of Page: %s, Total Pages: %s, Total:
%s".format(page.getNumber(), page.getSize(),
page.getTotalPages(), page.getTotalElements()));
foreach (user; page.getContent())
{
logDebug("User[%s] is: %s".format(user.id, user.name));
}
```
Example 2 for limit && offset :
```D
class User
{
mixin MakeModel;
@AutoIncrement
@PrimaryKey
int id;
string name;
}
auto query = em.createQuery!User("SELECT * FROM
User").setFirstResult(10).setMaxResults(20);
foreach (user; query.getResultList())
{
logDebug("User[%s] is: %s".format(user.id, user.name));

Hi everyone,
on behalf of the LDC team, I'm glad to announce the first beta
for LDC 1.6. The highlights of this version in a nutshell:
* Based on D 2.076.1.
* Experimental support for dynamic codegen at runtime ('manual
JIT').
* Many std.math functions are now CTFE-able.
Full release log and downloads:

Thanks to all contributors!
Fast update, thank you!
There is no version for FreeBSD?

Yes, thanks your project DDBC :) database is similar to PHP PDO library, no deps, api easy to use.
database 0.0.8 released
dlang database library: Database abstraction layer for D
programing language, support PostgreSQL / MySQL / SQLite.
Project:
https://github.com/huntlabs/database
## Database
Database abstraction layer for D programing language, support
PostgreSQL / MySQL / SQLite.
## Example
```D
import std.stdio;
import std.experimental.logger;
import database;
void main()
{
writeln("run database MySQL demo.");
auto db = new
Database("mysql://root:123456@localhost:3306/test?charset=utf-8");
int result = db.execute(`INSERT INTO user(username)
VALUES("test")`);
writeln(result);
foreach(row; db.query("SELECT * FROM user LIMIT 10"))
{
writeln(row["username"]);
}
db.close();
}
```
## Use DatabaseOption to instantiate a Database object
```D
auto options = new
DatabaseOption("mysql://root:123456@localhost:3306/test");
options.setMaximumConnection(5);
auto db = new Database(options);
db.execute("SET NAMES utf8");
```
## API
- int Database.execute(string sql) Return number of execute
result.
```D
int result = db.execute('INSERT INTO user(username)
VALUES("Brian")');
// if execute error ,db will throw an DatabaseException
```
- ResultSet Database.query(sql) Return ResultSet object for
query(SELECT).
```D
ResultSet rs = db.query("SELECT * FROM user LIMIT 10");
```
- Statement Database.prepare(sql) Create a prepared Statement
object.
```D
Statement stmt = db.prepare("SELECT * FROM user where username
= :username and age = :age LIMIT 10");
```
- Statement.setParameter(param, value) : bind param's value to
:param for sql.
```D
stmt.setParameter("username", "viile");
stmt.setParameter("age", 18);
```
- ResultSet Statement.query() Return ResultSet
```D
ResultSet rs = stmt.query();
foreach(row; rs)
{
writeln(row["username"]);
}
```
- Row Statement.fetch() Return Row
```D
Row row = stmt.fetch();
writeln(row["username"]);
```
- int Statement.execute() : return execute status for prepared
Statement object.
```D
int result = stmt.execute();
```
- Statement.lastInsertId() : Statement.execute() for insert sql,
return lastInsertId.

Given that LLVM has direct support for coroutines since 4.0 (https://llvm.org/docs/Coroutines.html) I've wondered if D (even just LDC D for starters) could use that to implement async/await or a similar feature. C++17 is supported it?

Melbourne Meetup
So I have foolishly started my first meetup, which is for D. http://www.meetup.com/D-Programming/ I'm still pretty much a newb at D, and the more I read the forums the more overwhelmed I am, but I thought it'd be good to catch up with any locals and see what people do. I'll probably try and get the first meetup going in the New Year, so any suggestions of topics will be greatly appreciated. :P Brian
