src/string/charset/unicode.c
DESCRIPTION
This file implements the charset functions for unicode data
static void set_graphemes
Sets static STRING *get_graphemes
Gets the graphemes from STRING static STRING *get_graphemes_inplace
Gets static STRING *to_charset
Converts input STRING static STRING *compose
If Parrot is built with ICU,
composes the STRING static STRING *decompose
Decompose function for unicode charset.
This function is not yet implemented.
static void upcase
Converts the STRING static void downcase
Converts all graphemes to lower-case,
for those graphemes which have cases.Throws an exception if ICU is not installed.
static void titlecase
Converts the string to title case,
for those characters which support cases.Throws an exception if ICU is not installed.
static void upcase_first
Converts the first grapheme in the STRING static void downcase_first
Converts the first grapheme in the STRING static void titlecase_first
Converts the first grapheme in STRING static INTVAL compare
Compares two STRINGs,
static INTVAL cs_rindex
Finds the last index of substring static UINTVAL validate
Returns 1 if the STRING static int u_iscclass
RT #48260: Not yet documented!!!
static INTVAL is_cclass
RT #48260: Not yet documented!!!
static INTVAL find_cclass
RT #48260: Not yet documented!!!
static INTVAL find_not_cclass
RT #48260: Not yet documented!!!
static STRING *string_from_codepoint
Returns a one-codepoint string for the given codepoint.
static size_t compute_hash
Computes the hash of the given STRING const CHARSET *Parrot_charset_unicode_init
Initializes the Unicode charset by installing all the necessary function pointers.
replace_count graphemes in STRING source_string starting at offset offset.
Gets the graphemes to be replaced from STRING insert_string.
source_string starting at offset.
Gets count graphemes total.
count graphemes in place from STRING source_string starting at offset offset.
Puts them into STRING dest_string.
src to unicode STRING dest.
src.
Attempts to denormalize the STRING into the ICU default,
NFC.If Parrot does not have ICU included,
throws an exception.
src to all upper-case graphemes,
for those characters which support upper-case versions.Throws an exception if ICU is not installed.
source_string to uppercase,
if the grapheme supports it.
Not implemented.
source_string to lower-case,
if the grapheme supports it.
Not implemented
source_string to title case,
if the string supports it.
Not implemented.
lhs and rhs.
Returns -1 if lhs < rhs.
Returns 0 if lhs = rhs.
Returns 1 if lhs > rhs.
search_string in STRING source_string,
starting from offset.
Not implemented.
src is a valid unicode string,
returns 0 otherwise.
src with starting seed value seed.
