//write an error message
Log.Add('Error x',etError);

//write formatted error message
Log.Add('Error is %s',[ErrorStr],etError);

Quick.Config: Load/Save a config as json file or Windows Registry keys. Create a descend class from TAppConfigJson or TAppConfigRegistry and add private variables will be loaded/saved. TAppConfiJson allow detect if config file was changed and do a config reload.

//create a class heritage
TMyConfig = class(TAppConfigJson)
private
    fName : string;
    fSurname : string;
    fStatus : Integer;
published
    property Name : string read fName write fName;

Quick.Threads: Thread safe classes.

TThreadedQueueCS: Version of TThreadedQueue with Critical Section.
TThreadObjectList: Thread safe Object List.
TThreadedQueueList: Thread safe Queue List. Autogrow and with Critical Section.
TAnonymousThread: Creates anonymous thread defining unchained Execute and OnTerminate methods. Use Execute_Sync and OnTerminate_Sync methods if code needs to update UI.
- Execute: Specify code to execute on start.
- Execute_Sync: Like Execute but runs code with syncronized thread method (avoids problems if your code updates UI).
- OnTerminate: Specify code to execute when task finishes.
- OnTerminate_Sync: Like OnTerminate but runs code with syncronized thread method (avoids problems if your code updates UI).
- Start: Starts thread execution.

//simple anonymousthread
TAnonymousThread.Execute(
      procedure

        cout('PRESS <ENTER> TO EXIT',etInfo);
      end)
    .Start;

TBackgroundsTasks: Launch tasks in background allowing number of concurrent workers. Use AddTask_Sync and OnTerminate_Sync methods if code needs to update UI.
- AddTask: Specify Task name, parameters to pass to anonymous method(If OwnedParams=true, task will free params on expiration task) and method than will be executed.
- AddTask_Sync: Like AddTask but runs code with synchronize thread method (avoids problems if your code updates UI).
- OnTerminate: Specify code to execute when task finishes.
- OnTerminate_Sync: Like OnTerminate but runs code with syncronized thread method (avoids problems if your code updates UI).
- OnException: Specify code to execute when task generates an exception.
- Start: Starts tasks execution.

    backgroundtasks := TBackgroundTasks.Create(10);
    for i := 1 to 100 do
    begin
      mytask := TMyTask.Create;
      mytask.Id := i;
      mytask.Name := 'Task' + i.ToString;
      backgroundtasks.AddTask([mytask],False,
                              procedure(task : ITask)
                              begin
                                cout('task %d started',[TMyTask(task.Param[0].AsObject).Id],etDebug);
                                TMyTask(task.Param[0].AsObject).DoJob;
                              end
                            ).OnException(
                              procedure(task : ITask; aException : Exception)
                              begin
                                cout('task %d failed (%s)',[TMyTask(task.Param[0].AsObject).Id,aException.Message],etError);
                              end
                            ).OnTerminated(
                              procedure(task : ITask)
                              begin
                                cout('task %d finished',[TMyTask(task.Param[0].AsObject).Id],etDebug);
                                TMyTask(task.Param[0].AsObject).Free;
                              end
                            ).Run;
    end;
    backgroundtasks.Start;

TScheduledTasks: Alternative to Timer. You can assign tasks with start time, repeat options and expiration date. Use AddTask_Sync, OnTerminate_Sync and OnExpired_Sync if code needs to update UI. You can assign anonymous methods to execute, exception, terminate and expiration events.
Add a task to execute:
- AddTask: Specify Task name, parameters to pass to anonymous method(If OwnedParams=true, task will free params on expiration task) and method than will be executed.
- AddTask_Sync: Like AddTask but runs code with synchronize thread method (avoids problems if your code updates UI).
Define events to control:
- OnTerminate: Specify code to execute when task finishes.
- OnTerminate_Sync: Like OnTerminate but runs code with syncronized thread method (avoids problems if your code updates UI).
- OnExpire: Specify code to execute when task expiration reached or task was cancelled.
- OnExpire_Sync: Like OnExpire but runs code with synchronized thread method (avoids problems if your code updates UI).
- OnException: Specify code to execute when task generates an exception.
Define when to start task:
- StartNow: Start task immediately.
- StartAt: Date and time to start task.
- StartTodayAt: Start task today at defined time.
- StartTomorrowAt: Start task tomorrow at defined time.
- StartOnDayChange: Start task when day changes.
- StartInMinutes: Start task after x minutes.
- StartInSeconds: Start task after x seconds.
Define if needs to repeat or not (if not defined a previous StartAt, StartOn, etc, task will be executed immediately):
- RunOnce: Task will be executed one time only.
- RepeatEvery: Can indicate repeat step over time and expiration date.
- RepeatEveryDay: Repeat task every day at same hour.
- RepeatEveryWeek: Repeat task every week at same hour.
Start/Stop scheduler:
- Start: Starts scheduler.
- Stop: Stops scheduler.

myjob := TMyJob.Create;
myjob.Name := Format('Run at %s and repeat every 1 second until %s',[DateTimeToStr(ScheduledDate),DateTimeToStr(ExpirationDate)]);
scheduledtasks.AddTask('Task1',[myjob],True,
                            procedure(task : ITask)
                            begin
                              cout('task "%s" started',[TMyTask(task.Param[0]).Name],etDebug);
                              TMyJob(task.Param[0]).DoJob;
                            end
                          ).OnException(
                            procedure(task : ITask; aException : Exception)
                            begin
                              cout('task "%s" failed (%s)',[TMyJob(task.Param[0]).Name,aException.Message],etError);
                            end
                          ).OnTerminated(
                            procedure(task : ITask)
                            begin
                              cout('task "%s" finished',[TMyJob(task.Param[0]).Name],etDebug);
                            end
                          ).OnExpired(
                            procedure(task : ITask)
                            begin
                              cout('task "%s" expired',[TMyJob(task.Param[0]).Name],etWarning);
                            end
                          ).StartAt(ScheduledDate
                          ).RepeatEvery(1,TTimeMeasure.tmSeconds,ExpirationDate);
scheduledtasks.Start;

Quick.Process: Manages windows processes.

//kill explorer process
KillProcess('explorer.exe');
//determine if an application is running
if IsProcessRunning('explorer.exe') then Showmessage('Explorer is running!');
//get username who is running an exe
writeln('Explorer.exe open by: ' + GetProcessUser('explorer.exe');
//gets handle of a window with a 20 seconds timeout
if FindWindowTimeout('MainWindow',20) then writeln('Window detected');

Quick.Process: Manages windows services.

//detect if a service is installed
if not ServiceIsPresent('localhost','MySvc') then raise Exception.Create('Service not installed!');
//Start a service
ServiceStart('localhost','MySvc');
//Uninstall a service
ServiceUninstall('MySvc');

Quick.Format: String format.

//Format bytes to MB, GB, TB...
FormatBytes(50000) //shows 50KB
FormatBytes(90000000) //shows 90MB

Quick.JsonSerializer: Serializes an object from/to json text. You can define if public or published will be processed (only Delphi, fpc rtti only supports published properties)

json := '{"name":"Peter","age":30}';
serializer := TJsonSerializer.Create(TSerializeLevel.slPublishedProperty);
try
   serializer.JsonToObject(user,json);
finally
   serializer.Free;
end;

Quick.AutoMapper: Map fields from one class to another class. Allows custom mappings to match different fields.

//Map values from User1 to User2
TMapper<TUser2>.Map(User);

//Map custom mappings
AutoMapper := TAutoMapper<TUser,TUser2>.Create;
AutoMapper.CustomMapping.AddMap('Cash','Money');
AutoMapper.CustomMapping.AddMap('Id','IdUser');
User2 := AutoMapper.Map(User);

Quick.JsonRecord: Used as a DTO class, with json serialize and mapping functions included.

type
   TUser = class(TJsonRecord)
   private
      fName : string;
      fAge : Integer;
   published
      property Name : string read fName write fName;
      property Age : Integer read fAge write fAge;
   end;
var
   user, user2 : TUser;
begin
   user := TUser.Create;
   //show as json string
   Writeln(user.ToJson);
   //mapping to other class
   user.Mapto(User2);
   Writeln(user2.ToJson);
   //load from file
   user.LoadFromFile('.\user.json');
   //save to file
   user2.SaveToFile('.\user2.json');
end;

Quick.Lists: Improved lists with indexing or search features.

TIndexedObjectList: Allows fast hashed searches by object properties or fields.
TSearchObjectList: Allows iteration search by object properties or fields.

var
   users : TIndexedObjectList<TUser>;
begin
   users := TIndexedObjectList<TUser>.Create(True);
   //create index by property "Name"
   users.Indexes.Add('Name','Name',TClassField.cfProperty);
   //create index by private field "Id"
   users.Indexes.Add('Id','fId',TClassField.cfField);
   //get user by "Name" index
   writeln(users.Get('Name','Peter').SurName);
end;
