User interface > Translation options > Type options > String types
At the type options you can chose how the string types AnsiString, WideString and String are translated.
If Delphi string is selected, the translated code will use classes for AnsiString, WideString and UnicodeString. In C++Builder these classes are provided. If you chose this option for other compilers, you have to create these classes yourself. They have to be 1 based and have to obey the specifications from Embarcadero:
http://docwiki.embarcadero.com/RADStudio/Tokyo/en/String_Types_(Delphi)
If Standard string is selected, the following typedef's are needed:
typedef std::string AnsiString
typedef std::wstring WideString
typedef std::wstring UnicodeString
Delphi functions for strings will be converted to functions for AnsiString/UnicodeString or std::string/std::wstring. Examples:
var
s1, s2 : String;
begin
Length(s1);
SetLength(s1, 10);
s1 := '12345678';
s2 := copy(s1, 3, 4);
Delete(s1, 3, 2);
Pos(s1, s2);
->
Delphi string Standard string
s1.Length(); s1.size();
s1.SetLength(10); s1.resize(10);
s1 = L"12345678"; s1 = L"12345678";
s2 = s1.SubString(3, 4); s2 = s1.substr(3-1, 4);
s1.Delete(3, 2); s1.erase(3-1, 2);
s2.Pos(s1); s2.find(s1);
d2c string is an experimental own AnsiString/UnicodeString based on std::string/std::wstring
According to the chosen "String" as option String will be treated either as AnsiString or as UnicodeString.
var
S: String:
begin
S := 'hallo';
is translated for an Ansi association to:
String S;
S = "hallo";
and for the Unicode association to
String S;
S = L"hallo";
