Functions
void string_set_data_directory(const char *dir)- Set the directory where ICU finds its data files (encodings, locales, etc.).
void string_fill_from_buffer(Interp *interpreter, const void *buffer, UINTVAL len, const char *encoding_name, STRING *s)- Creates a Parrot string from an "external" buffer, converting from any supported encoding into Parrot string's internal format.
Character Property Functions
UINTVAL Parrot_char_digit_value(Interp *interpreter, UINTVAL character)- Returns the decimal digit value of the specified character if it is a decimal digit character. If not, then -1 is returned.
- Note that as currently written,
Parrot_char_digit_value()can correctly return the decimal digit value of characters for whichParrot_char_is_digit()returns false. INTVAL Parrot_char_is_alnum(Interp *interpreter, UINTVAL character)- Returns whether the specified character is an alphanumeric character.
INTVAL Parrot_char_is_alpha(Interp *interpreter, UINTVAL character)- Returns whether the specified character is an letter character.
INTVAL Parrot_char_is_ascii(Interp *interpreter, UINTVAL character)- Returns whether the specified character is an ASCII character.
INTVAL Parrot_char_is_blank(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a "blank" or "horizontal space", a character that visibly separates words on a line.
INTVAL Parrot_char_is_cntrl(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a control character.
INTVAL Parrot_char_is_digit(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a digit character.
INTVAL Parrot_char_is_graph(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a a "graphic" character (printable, excluding spaces).
INTVAL Parrot_char_is_lower(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a lowercase letter.
INTVAL Parrot_char_is_print(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a printable character.
INTVAL Parrot_char_is_punct(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a punctuation character.
INTVAL Parrot_char_is_space(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a space character.
INTVAL Parrot_char_is_upper(Interp *interpreter, UINTVAL character)- Returns whether the specified character is an uppercase character.
INTVAL Parrot_char_is_xdigit(Interp *interpreter, UINTVAL character)- Returns whether the specified character is a hexadecimal digit character.
