String functions

Functions to manipulate and format strings.

Str_Format

Returns formatted string using format specifiers

Format specifiers:

  • %s - inserts a string
  • %i - inserts an integer number
  • %x - inserts an integer in hexadecimal
  • %f - inserts a floating point number
  • %b - inserts a logical expression
  • %p - inserts a pointer
1
func string Str_Format( var string format, ... ) {};
  • return - formatted string

Examples

Very powerful function, can be used to streamline strings used in the scripts as well as optimize them for translations.

Define constants containing the string with format specifiers. 

1
2
const string MENU_SAVE = "Slot %i - press ENTER to save in this slot.";
const string MENU_LOAD = "Slot %i - press ENTER to load saved game.";
Then define two format functions as such: 
1
2
3
4
func string GetSaveSlotString (var int number)
{
    return Str_format(MENU_SAVE, number);
};

4
func string GetLoadSlotString (var int number)
{
    return Str_format(MENU_LOAD, number);
};

Tip

Since the whole translatable string is saved in one constant, it is very easy for translators to change the word order. This was not possible to do without code change to the ConcatStrings function calls within the scripts.
With this simple change, translators have to translate only 2 strings instead of 30 (15 + 15 slots) and only 2 strings are compiled into the compiled Menu.dat file.

Str_GetLocalizedString

Returns a string in the current language, otherwise in English. Arguments MUST be encoded in UTF-8! The result string will be converted to appropriate ANSI string.
