string_format [function]

string_format( [int prealloc,] string text, ... )

parses all format specifiers in text and returns the result

see fmt_text if you don't need the position (argument index) specifications

• prealloc specifies number of bytes to be preallocated on the buffer to avoid continuous reallocations during string generation
• the format specifier has the form {<id>:<specifier>} where "id" is the argument index to use and specifier is a fmt_text specifier
• argument indices to be used in specifiers start from 1

print string_format( "{1:d} -> {1:x}", 1337 ); // prints "1337 -> 539"
