UTF-8 aware string operations that can be used as extension methods. Use with: using loreline.Utf8;

Static Members

uLength(str: String): Int

UTF-8 aware string length

Name Type
str String
Returns
Int
uSubstr(str: String, pos: Int, ?len: Int): String

UTF-8 aware substring extraction

Name Type Default
str String
pos Int
len Int (optional)
Returns
String
uSubstring(str: String, startIndex: Int, ?endIndex: Int): String

UTF-8 aware substring with end position

Name Type Default
str String
startIndex Int
endIndex Int (optional)
Returns
String
uCharCodeAt(str: String, pos: Int): Int

UTF-8 aware character code at position

Name Type
str String
pos Int
Returns
Int
uIndexOf(str: String, substr: String, ?startIndex: Int): Int

UTF-8 aware indexOf

Name Type Default
str String
substr String
startIndex Int (optional)
Returns
Int
uLastIndexOf(str: String, substr: String, ?startIndex: Int): Int

UTF-8 aware lastIndexOf

Name Type Default
str String
substr String
startIndex Int (optional)
Returns

uToChars(str: String): Array<String>

UTF-8 aware string to char array

Name Type
str String
Returns
Array<String>
uCharAt(str: String, pos: Int): String

UTF-8 aware charAt

Name Type
str String
pos Int
Returns
String
toCodes(str: String): haxe.ds.Vector<Int>

Decode a string into a fixed-size Vector of code points in a single forward pass (O(n) on every target). This is the linear decode that lets scanners index characters in O(1); a naive uCharCodeAt/uToChars loop would itself be O(n^2) on neko/php.

Name Type
str String
Returns
haxe.ds.Vector<Int>
