| 1 | + | ## Opis | |
| 2 | + | ||
| 3 | + | Moduł efmtf to zestaw klas i procedur umożliwiający formatowanie ciągów tekstowych na podstawie parametrów przekazanych w tablicy, z możliwością dodawania własnych reguł formatowania dla zmiennych obiektowych oraz wsparciem dla języka SQL. Moduł jest nadal zależny od standardowych funkcji FormatDateTime oraz Format. | |
| 4 | + | ||
| 5 | + | ## Przykłady | |
| 6 | + | ||
| 7 | + | Formatowanie z adresowaniem zmiennych | |
| 8 | + | ||
| 9 | + | ``` pascal | |
| 10 | + | S := Fmt('string: {0:s}, integer: {1:d}, money: {2:m}, float: {2:f}', ['test', 1, 22.3]); | |
| 11 | + | wynik: string: test, integer: 1, money: 22.30 zł, float: 22.3 | |
| 12 | + | ``` | |
| 13 | + | ||
| 14 | + | Adresowanie mieszane i domyślne formatowanie | |
| 15 | + | ||
| 16 | + | ``` pascal | |
| 17 | + | S := Fmt('string: {}, integer: {}, money: {:m}, float: {2}', ['test', 1, 22.3]); | |
| 18 | + | wynik: string: test, integer: 1, money: 22.30 zł, float: 22.3 | |
| 19 | + | ``` | |
| 20 | + | ||
| 21 | + | Wsparcie dla SQL (parametry pisane z dużej litery): | |
| 22 | + | ||
| 23 | + | ``` pascal | |
| 24 | + | S := Fmt('SELECT * FROM employees WHERE FirstName = {:S} AND DateHired < {:TD};', ['John', Now]); | |
| 25 | + | wynik: SELECT * FROM employees WHERE FirstName = 'John' AND DateHired < '2009-01-01'; | |
| 26 | + | ``` | |
| 27 | + | ||
| 28 | + | Wsparcie dla parametrów globalnych | |
| 29 | + | ||
| 30 | + | ``` pascal | |
| 31 | + | SetParam('test', 'World'); | |
| 32 | + | S := Fmt('Hello {$test}!'); | |
| 33 | + | ||
| 34 | + | wynik: Hello World! | |
| 35 | + | ``` | |
| 36 | + | ||
| 37 | + | Wsparcie dla formatowania zmiennych obiektowych: | |
| 38 | + | ||
| 39 | + | ``` pascal | |
| 40 | + | // funkcja formatująca | |
| 41 | + | function FormFmt(AObject: TObject; Mode: Char; Param: string): string; | |
| 42 | + | var | |
| 43 | + | f: TForm; | |
| 44 | + | begin | |
| 45 | + | if AObject is TForm then | |
| 46 | + | begin | |
| 47 | + | f := TForm(AObject); | |
| 48 | + | if Param = 'caption' then | |
| 49 | + | Result := f.Caption | |
| 50 | + | else | |
| 51 | + | Result := f.Name; | |
| 52 | + | end; | |
| 53 | + | end; | |
| 54 | + | ||
| 55 | + | // przykład | |
| 56 | + | RegisterFunction(TForm, FormFmt); | |
| 57 | + | S := Fmt('caption: {0:scaption}, name: {0:s}', [Form1]); | |
| 58 | + | ``` | |
| 59 | + | ||
| 60 | + | Escaped String | |
| 61 | + | ||
| 62 | + | ``` pascal | |
| 63 | + | S := Fmt('\{2 + 2\} * 2, {:SE}', ['Hello'#13#10'World!']); | |
| 64 | + | ||
| 65 | + | wynik: {2 + 2} * 2, 'Hello\r\nWorld!' | |
| 66 | + | ``` | |
