PBClient for Redis for Delphi and C++ Builder

PBClient for Redis

Latest version: 1.0.0.0

Category: Databases Tags: Redis, Delphi, C++ Builder

Trial

Component for handling full Redis database API with a native-like command syntax.

Probably you already heard of Redis. If not, we strongly recommend to get in touch with this wonderful NoSQL database either on Wikipedia, or on the developer website.

Now you know, what is Redis. Maybe you even heard, that a huge amount of famous developers and companies are using this database. Redis can run almost on any OS. Redis clients are developed for mostly all popular programming languages. But until recently Delphi was undeservingly deprived. No one has offered a library or components for handling full Redis API. We are happy to announce that our company is offering our clients such a component.

Working with Redis in Delphi became so simple, that our component almost doesn’t require a special documentation. The whole documentation is in fact a rewritten Redis native documentation with adjusted command syntax.

PBClient for Redis will provide you with the whole Redis functionality out of the box:

TPBRedisClient.AUTH
TPBRedisClient.GETSET
TPBRedisClient.INCRBYFLOAT
TPBRedisClient.CLUSTER_ADDSLOTS

If new commands will be released, you will still be able to access them with a RUN command returning a JSON object:

function TPBRedisClient.Run(const commandname: string;
  Parameters: TStringArray): string;

procedure TPBRedisClient.Run(var Result: TJSONObject; const commandname: string;
  Parameters: TStringArray);

For instance, this 2 commands are equivalent:

1
2
3

PBRedisClient1.HSET('key', 'field', 'value');

PBRedisClient1.Run('HSET', ['key', 'field', 'value']);

Source code promise

In case our component will become obsolete and we no longer support it, we will provide you its source code. So you don’t have to worry about a replacement.

References:
> QSG code example provided with the installer
> RedisClient native commands

After installation, a group PyBridge will appear in the Tool Palette of Delphi, where you can find the new component TPBRedisClient.

New component TPBRedisClient can be found in the Tool Palette under PyBridge group

Place TPBRedisClient onto the form and set up its main properties:

AutoConnect – set to True for automatic connection to Redis
RedisServer – setup host, password and port number to access Redis

Now PBClient for Redis is ready to be used. To demonstrate how it works, let’s create a text-chat application which can:

do operations with database keys
subscribe and publish messages to a channel

PBRedisClientDemo layout

ButtonClick event handler procedures of the ‘SET’, ‘GET’ and ‘INCR’ buttons:

procedure TForm1.SETButtonClick(Sender: TObject);
begin
  PBRedisClient1.&SET(Edit1.Text, Edit2.Text);
  Memo1.Lines.Add('SET ' + Edit1.Text + ' ' + Edit2.Text);
end;

procedure TForm1.GETButtonClick(Sender: TObject);
var
  strval: String;
  intval: Integer;
begin
  strval:= PBRedisClient1.GET(Edit1.Text);
  Memo1.Lines.Add('GET '+ Edit1.Text + '= ' + strval);
end;

procedure TForm1.INCRButtonClick(Sender: TObject);
var
  n: Integer;
  strval: String;
begin
  if not TryStrToInt(Edit2.Text, n) then begin
    Memo1.Lines.Add('It is not a digit!');
    Edit2.Text:='123';
    SETButtonClick(Sender);
  end;
  PBRedisClient1.INCR(Edit1.Text);
  GETButtonClick(Sender);
end;

ButtonClick event handler procedures of the ‘SUBSCRIBE’, ‘PUBLISH’ and ‘UNSUBSCRIBE’ buttons:

procedure TForm1.SUBSCRIBEButtonClick(Sender: TObject);
begin
  PBRedisClient1.SUBSCRIBE('ChannelDemo');
  Memo1.Lines.Add('SUBSCRIBED to the ' + '"ChannelDemo"');
end;

procedure TForm1.PUBLISHButtonClick(Sender: TObject);
begin
  PBRedisClient1.PUBLISH('ChannelDemo', Edit3.Text);
end;

procedure TForm1.UNSUBSCRIBEButtonClick(Sender: TObject);
begin
  PBRedisClient1.UNSUBSCRIBE;
  Memo1.Lines.Add('UNSUBSCRIBED from the ' + '"ChannelDemo"');
end;

OnGetChannelMessage event will add a line to the Memo:

procedure TForm1.PBRedisSubscriber1GetMessage(const AChannel, AMessage: string);
begin
  Memo1.Lines.Add(AChannel + ': ' + AMessage);
end;

Start several instances of the program, subscribe them to the same channel (in the trial version only the default “Channel Demo” is available). Now you can exchange messages and do operations with database keys.

This example demonstrates how easy it is to develop Delphi applications relying on Redis with the help of PBClient for Redis. Now you can also enjoy the full power of Redis in your applications!
