end;
```
**Quick.YAML:**
--
Yaml object structure.
**TYamlObject:** A Yaml object is and array of YamlValue pairs.
```delphi
//create Yaml object from yaml text
yamlobj.ParseYamlValue(aYaml)
//add a pair
yamlobj.AddPair('Name','Mike');

if TExpressionParser.Validate(user,('(Age > 30) AND (Dept.Name = "Financial")') then
begin
//do something
end;
if TExpressionParser.Validate(user,('(20 > 30) OR (5 > 3)') then
begin
//do something
end;
```
**Quick.Linq:**
--
Makes Linq queries to any TObjectList, TList, TArray and TXArray, performing Select by complex Where like SQL syntax, update and order over your list. Where clauses uses namespaces to determine nested properties. LinQ can search for a element into a property array.
Now includes and TArray helper to add, remove and search with regular expressions into array.
- **From:** Array, XArray or TObjectList to use.
- **Where:** Expression to search. You can use a dots to define property path.
- **SelectAll:** Returns an array of objects matching where clause
- **SelectTop:** Returns top x objects matching where clause.
- **SelectFirst:** Returns first object matching where clause.
- **SelectLast:** Returns last object matching where clause.
- **OrderBy:** Define order of returned list.
- **Update:** Update fields of matching where clause.
- **Delete:** Delete objectes matching where clause.
- **Count:** Return number of elements matching where clause.
```delphi
//Select multi conditional
for user in TLinq.From(userslist).Where('(Name = ?) OR (SurName = ?) OR (SurName = ?)',['Peter','Smith','Huan']).Select do
begin
//do something
end;
//Select like and update field
TLinq.From(userlist).Where('SurName Like ?',['%son']).SelectFirst.Name := 'Robert';
//Select top and Order by field
for user in TLinq.From(userlist).Where('Age > ?',[18]).SelectTop(10).OrderBy('Name') do
begin
//do something
end;
//update fields by conditional
TLinq.From(userlist).Where('Name = ?',['Peter']).Update(['Name'],['Joe']);
//count results
numusers := TLinq.From(userlist).Where('(Age > ?) AND (Age < ?)',[30,40]).Count;
```
**Quick.HTTPServer:**
--
TCustomHttpServer is a simple interfaced HttpServer with own HttpRequest and HttpResponse implementations to allow easy httpserver engine changes.
You can enable custom error pages to return customized pages and dynamic error pages.
THttpServer is the IndyHttpServer implementation, but you can define your own.
```delphi
TMyHttpServer = class(THttpServer)
public
procedure ProcessRequest(aRequest: IHttpRequest; aResponse: IHttpResponse); override;
end;
procedure TMyHttpServer.ProcessRequest(aRequest: IHttpRequest; aResponse: IHttpResponse);
begin
aResponse.ContentText := 'Hello world!';
end;
```
**Quick.MemoryCache:**
--
Caches objects or strings with an expiration time, to avoid generate this info everytime is needed (database queries, hard to calculate info, etc). TMemoryCache allows to cache objects and strings. Generic version TMemoryCache allows to cache a defined type only.
- Create: Could be defined Purge interval and Serialization and Compression engines. By default serializes as Json and compress with gzip.
```delphi
//create MemoryCache with 10 seconds purge interval
cache := TMemoryCache.Create(10);
//create MemoryCache for a type
cache := TMemoryCache.Create;
```
- Compression: Enables/Disables cache data compression.
- CachedObjects: Returns number of objects currently in cache.
- CacheSize: Returns size in bytes of all objects currently in cache. Real memory used depends of memory managers or architecture. This value is the real size of data bytes.
- PurgeInterval: Interval purge job tries to find expired objects to remove from cache (Default value 20 seconds).
- OnCacheFlushed: When cache is flushed.
- OnBeginPurgerJob: When PurgerJob starts.
- OnEndPurgerJob: When PurgerJob ends.
- Flush: Removes all cache objects.
- SetValue: Adds an object to cache. You can indicate expiration date or number of milliseconds to expire. If not defined cache will be infinity. MemoryCache can store objects or strings.
```delphi
//set string to cache without expiration
cache.SetValue('mystring','hello world');
//set string to cache with expiration to 10 seconds
cache.SetValue('mystring','this cache will expire in 10 seconds';
//set object to cache
cache.SetValue('Obj1',valueobj);
```
- TryGetValue: Tries to get and object from cache. Returns false if object doesn't exists or it's expired.
```delphi
//get string query result
cache.GetValue('Query12');
//get integer
cache.TryGetValue('number',valueint);
//get object
cache.TryGetValue('Obj1',valueobj);
```
- RemoveValue: Removes an object from cache.
- **Cache Engine providers:**
- TCacheSerializerJSON: Uses JSON to serialize cache data.
- TCacheCompressorGzip: Uses Gzip to compress cache data.
- TCacheCompressorLZO: Uses LZO to compress cache data.
```delphi
//create MemoryCache with 20 seconds purge interval and compression with LZO engine
cache := TMemoryCache.Create(10,nil,TCacheCompressorLZO.Create);
```
**Quick.IOC:**
--
Inversion of Control manager allows autocreate interfaced o instanced object or autoinject them in constructor classes, to avoid dependency.
Create a container to manage dependency injection.
```delphi
iocContainer := TIocContainer.Create;
```
**Register Types:**
You need to register types before you can inject them. A Type can be registered as Singleton, Transient.
**Singleton**: Life cycle will be one single instance for all injections, similar to a Global variable.
**Transient**: Life cycle will be one instance per each injection.
Register an interface type into container as transient:
```delphi
iocContainer.RegisterType.AsTransient;
```
Register an interface type as singleton, delegating construction:
```delphi
iocContainer.RegisterType.AsSingleTon.DelegateTo(
function : TSumService
begin
Result := TSumService.Create;
end
);
```
**Register Instances:**
Register a named instance object as transient, delegating construction:
```delphi
iocContainer.RegisterInstance('one').AsTransient.DelegateTo(
function : TDivideService
begin
Result := TDivideService.Create(True);
end
);
```
**Register Options:**
Register IOptions (only singleton):
```delphi
iocContainer.RegisterOptions(MyOptions);
```
**Resolve Types:**
AbtractFactory:
Creates a class trying to resolve all creation method parameter with dependency injection.
```delphi
MyClass := iocContainer.AbstractFactory(TMyClass);
```
Resolve an interface dependency:
```delphi
multservice := iocContainer.Resolve;
result := multservice.Mult(2,4);
```
**Resolve Instances:**
Resolve a named instance dependency:
```delphi
divideservice := iocContainer.Resolve('other');
result := divideservice.Divide(100,2);
```
Interface instances will be freed automatically, but instance dependencies only will be freed if defined as singleton, transient instances will be destroyed by code.
**Quick.Options:**
--
You define sections as classes and saves as single file settings. Works similar to dotnet Options. Options file can be in JSON or YAML format.
Define your option class inherited from TOptions and all published properties will be load/save.
Create options container, with JsonSerializer and reloading on change:
```delphi
Options := TOptionsContainer.Create('.\options.conf',TJsonOptionsSerializer.Create,True);
```
Add a section to your container options:
```delphi
Options.AddSection('Logging')
```
**Configure Options:**
You can define section name to save into file and delegate configuration default settings and validating values:
```delphi
Options.AddSection('Logging').ConfigureOptions(
procedure(aOptions : TLoggingOptions)
begin
aOptions.Path := 'C:\';
end
).ValidateOptions;
```
**Validate Options:**
Validate options allows verify if option settings are setted between defined ranges. This validation needs previously assigned custom attributes to properties in your TOptions class.
- **StringLength(max,messagestr):** Allows define max length in string properties, returning messagestr if length greater than max.
- **Range(min,max,messagestr):** Allows define a range of min and max values permitted, returning messagestr if value length outbounds margins.
```delphi
TLoggingOptions = class(TOptions)
private
fPath : string;
published
[Required, StringLength(255,'Path too long')]
property Path : string read fPath write fPath;
[Range(0.0,5.2)]
property Level : Double read fLevel write fLevel;
end;
```
**Use Options:**
To retrieve option section:
```delphi
LoggingOptions := Options.GetSection;
LoggginOptions.Path := 'C:\Path';
```
**Use IOptions:**
IOptions is a dependency injectable interface to TOptions. You can register with IocContainer.RegisterOptions to make injectable into constructor methods.
```delphi
UIOptions := Options.GetSectionInterface.Value;
UIOptions.WindowColor := clBlue;
```
**Load/Save Options:**
Load options from file settings:
```delphi
options.Load;
```
Save options to file settings:
```delphi
options.Save;
```
If you defined container creation with ReloadOnChanged parameter to true, every time file settings is changed, configuration will be reloaded. If you need to control when to reload, you can listen to the event:
```
Options.OnFileModified := procedure
begin
cout('Detected config file modification!',etWarning);
end;
```
**Quick.Pooling:**
--
Define pool of connection, threads or any object you want to control to avoid resource consum like database connections, http clients, etc...
Create http client pool:
```delphi
pool := TObjectPool.Create(5,5000,procedure(var aInstance : THTTPClient)
begin
aInstance := THTTPClient.Create;
aInstante.UserAgent := 'MyAgent';
end);
```
Get object from pool:
```delphi
httpcli := pool.Get.Item;
statuscode := httpcli.Get('https://www.mydomain.com').StatusCode;
```
**Quick.Collections:**
--
Defines interfaced List and Objectlist with linQ support inherited.
- TXList / IList: Interfaced List allowing LinQ regEx search/remove/update.
```delphi
myarray := ['Joe','Mat','Lee'];
//search for regex match
cout('Search for regex match',ccYellow);
for name in myarray.Where('e$',True).Select do
begin
cout('User %s ends with "e"',[name],etInfo);
end;
```
- TXObjectList / IObjectList: Interfaced ObjectList allowing LinQ predicate or expression search/remove/update.
Expression search:
```delphi
user := ListObj.Where('Profile.Name = ?',['Lee']).SelectFirst;
```
Expression search for item array:
```delphi
users := ListObj.Where('Roles CONTAINS ?',['SuperAdmin']).Select;
```
Predicate search:
```delphi
user := ListObj.Where(function(aUser : TUser) : Boolean
begin
Result := aUser.Name.StartsWith('J');
end).SelectFirst;
if user <> nil then cout('%s starts with J letter',[user.Name],etInfo);
```
See Quick.Linq section to view more functions allowed.
**Quick.Template:**
--
String template replacing using a dictionary or delegate function. You can specify quoted token chars.
Replace passing a dictionary:
```delphi
dict := TDictionary.Create;
dict.Add('User','John');
dict.Add('Age','20');
dict.Add('SurName','Peterson');
mytemplate := 'User {{User}} {{SurName}} are {{Age}} years old.';
template := TStringTemplate.Create('{{','}}',dict);
Result := template.Replace(mytemplate);
```
Replace with delegate function:
```delphi
mytemplate := 'User {{User}} {{SurName}} are {{Age}} years old.';
template := TStringTemplate.Create('{{','}}',function(const aToken : string) : string
begin
if token = 'User' then Result := 'John'
else if token = 'Surname' then Result := 'Peterson'
else if token = 'Age' then Result := '20';
end);
Result := template.Replace(mytemplate);
```
**Quick.Debug.Utils:**
--
Debug utils to check performance and get enter and exit method checkpoint.Define with a Debug a compiler directive to only be active when your app is compiled in debug mode.
On console apps uses console out by default. You can pass a logger to output in:
```delphi
TDebugUtils.SetLogger(ilogger);
```
Trace a part of your code:
```delphi
function TCalculator.Subs(a, b: Int64): Int64;
begin
{$IFDEF DEBUG}
TDebugger.Trace(Self,Format('Substract %d - %d',[a,b]));
{$ENDIF}
Result := a - b;
//simulate working for 200ms
Sleep(200);
end;
//Returns:
//29-06-2020 23:31:41.391 [TRACE] TCalculator -> Substract 30 - 12
```
Calculate time to process from point to exit function:
```delphi
function TCalculator.Sum(a, b: Int64): Int64;
begin
{$IFDEF DEBUG}
TDebugger.TimeIt(Self,'Sum',Format('Sum %d + %d',[a,b]));
{$ENDIF}
Result := a + b;
//simulate working for 1 seconds
Sleep(1000);
end;
//Returns:
//29-06-2020 22:58:45.808 [CHRONO] TCalculator.Sum -> Sum 100 + 50 = 1,00s
```
Calculate time to process from point to point and exit function:
```delphi
function TCalculator.Divide(a, b: Int64): Double;
begin
{$IFDEF DEBUG}
var crono := TDebugger.TimeIt(Self,'Divide',Format('Divide %d / %d',[a,b]));
{$ENDIF}
Result := a / b;
//simulate working for 500ms
Sleep(500);
{$IFDEF DEBUG}
crono.BreakPoint('Only divide');
{$ENDIF}
//simulate working for 1 second
Sleep(1000);
{$IFDEF DEBUG}
crono.BreakPoint('Only Sleep');
{$ENDIF}
end;
//Returns:
//29-06-2020 23:25:46.223 [CHRONO] TCalculator.Divide -> First point = 500,18ms
//29-06-2020 23:25:47.224 [CHRONO] TCalculator.Divide -> Second point = 1,00s
//29-06-2020 23:25:47.225 [CHRONO] TCalculator.Divide -> Divide 10 / 2 = 1,50s
```
Get notification when enter and exit function, and times it:
```delphi
function TCalculator.Mult(a, b: Int64): Int64;
begin
{$IFDEF DEBUG}
TDebugger.Enter(Self,'Mult').TimeIt;
{$ENDIF}
Result := a * b;
//simulate working for 2 seconds
Sleep(2000);
end;
//Returns:
//29-06-2020 22:58:45.808 [ENTER] >> TCalculator.Mult
//29-06-2020 22:58:47.810 [EXIT] >> TCalculator.Mult in 2,00s
```
**Quick.Parameters:**
--
Working with commandline parameters will be easy using commandline extension.
Define a class inherited from TParameters or TServiceParameters (if working with QuickAppServices) with your possible arguments as published properties:
```delphi
uses
Quick.Parameters;
type
TCommand = (Copy, Move, Remove);
TMyMode = (mdAdd, mdSelect, mdRemove);
[CommandDescription('Simple console application example with Quick.Parameters')]
TMyParameter = class(TParameters)
private
fCommand : TCommand;
fHost : string;
fPort : Integer;
fRetries : Integer;
fUseTCP : Boolean;
fConfigFile: string;
fSilent: Boolean;
fMyMode: TMyMode;
fLogErrorsConsole: Boolean;
fLogErrors: Boolean;
fShowReport: Boolean;
published
[ParamCommand(1)]
[ParamRequired]
[ParamHelp('Command action.','command-action')]
property Command : TCommand read fCommand write fCommand;
[ParamName('HostName'),ParamRequired]
[ParamHelp('Define host to connect.','host')]
property Host : string read fHost write fHost;
[ParamName('Port','p')]
[ParamValueIsNextParam]
[ParamHelp('Define Port to connect (default 80)','port')]
property Port : Integer read fPort write fPort;
[ParamHelp('Number of max retries.')]
property Retries : Integer read fRetries write fRetries;
[ParamHelp('Path to config.','path')]
[ParamName('Config-file')]
property ConfigFile : String read fConfigFile write fConfigFile;
[ParamHelp('Silent mode.')]
property Silent : Boolean read fSilent write fSilent;
[ParamHelp('Modes (mdAdd, mdSelect, mdRemove)')]
property Mode : TMyMode read fMyMode write fMyMode;
end;
```
Use param:
```delphi
params := TMyParameter.Create;
```
When you call your exe with --help you get documentation. If you need to check for a switch or value, you can do like this:
```delphi
if params.Port = 0 then ...
if params.Silent then ...
```
QuickParameters uses custom attributes to define special parameter conditions:
- **CommandDescription:** Defines text to describe your application in help documentation.
- **ParamCommand(number):** Defines static position into commandline for single parameters.
- **ParamName(name,alias):** Define a diferent name for parameter. Allows to use special characters not allowed for class properties (like file-name or config.file). Optional Alias argument defines an alternative (normally short name) parameter name.
- **ParamHelp(helptext,valuename):** Defines a commandline help text and value name in usage section.
- **ParamSwitchChar(sign):** Defines string or char to indicate switch or parameter. If not defined, a double dash (--) will be used by default.
- **ParamValueSeparator(sign):** Defines string or char to separate parameter name from value (filename=config.json). If not defined, equal sign (=) will be used by default.
- **ParamValueIsNextParam:** Defines a parameter with a value without value separator (filename c:\config.ini)
- **ParamRequired:** Defines a parameter as required. If param not found, an exception will be raised.
QuickParameter automatically checks for value types. If you define a parameter value as Integer, and pass an alfanumeric, an exception will be raised.
Help customization:
You can define your own color customization with ColorizeHelp. Enabled property will use custom colors, otherwise b/w will be used.
```delphi
Parameters.ColorizeHelp.Enabled := True;
Parameters.ColorizeHelp.CommandName := ccCyan;
Parameters.ColorizeHelp.CommandUsage := ccBlue;
```
When parameters detects help parameter, help documentation will be showed.
Parameters.ShowHelp: Shows help documentation, generated automatically:
```
