String Formatting

Tools for complex string formatting and template replacement.

Advanced Formatting

Format

The Format function provides powerful template-based formatting similar to C's printf or Delphi's Format.

Specifier	Description	Example
`%d`	Decimal Integer	`Format('%d', [42])` -> `42`
`%x`	Hexadecimal	`Format('%x', [255])` -> `FF`
`%f`	Floating point	`Format('%.2f', [3.1415])` -> `3.14`
`%e`	Scientific notation	`Format('%e', [1000])` -> `1.00E+003`
`%g`	General number	`Format('%g', [0.00001])` -> `1E-5`
`%n`	Number with separators	`Format('%n', [1234.5])` -> `1,234.50`
`%s`	String	`Format('Hi %s', ['Bob'])` -> `Hi Bob`
`%m`	Money	`Format('%m', [10.5])` -> `$10.50`

var s := Format(
  'Total: %d items in %.2f seconds',
  [ 10, 1.234 ]
);
PrintLn(s);

Result

Total: 10 items in 1.23 seconds

Pattern Replacement

The StrReplaceMacros function (or .ReplaceMacros helper) allows for template-style replacements using an array of key-value pairs.

var template := 'Hello [NAME], welcome to [PLACE].';
var data := ['NAME', 'Alice', 'PLACE', 'the Compendium'];

var msg := template.ReplaceMacros(data, '[', ']');
PrintLn(msg);

Result

Hello Alice, welcome to the Compendium.
