Detailed Description
Functions for identifying and converting unicode characters and representation forms.
Function Documentation
◆ CountIndent()
| std::size_t CountIndent | ( | std::u32string_view | s, |
| std::size_t | begin = 0 |
||
| ) |
Calculates and returns the number of spaces in the beginning of the given string.
- Parameters
-
s The string to be searched. begin An optional beginning index from which to count the spaces.
◆ FromCP437()
| std::u32string FromCP437 | ( | std::string_view | s | ) |
Converts given text, assumed to be CP437 encoded, into a sequence of unicode codepoints
◆ FromUTF8()
| std::u32string FromUTF8 | ( | std::string_view | s | ) |
This function is optimized for performance. A simple (but incomplete) implementation is shown in if-0. Surrogate pairs are detected and parsed properly, if they appear within a single string.
◆ isalnum()
| bool isalnum | ( | char32_t | c | ) |
- Returns
- true if given code index represents an alphabet or a numeric digit
◆ isalnum_()
| bool isalnum_ | ( | char32_t | c | ) |
- Returns
- true if given code index represents an alphabet or a numeric digit or the underscore
◆ isalpha()
| bool isalpha | ( | char32_t | c | ) |
- Returns
- true if given code index represents an alphabet
◆ isblank()
| bool isblank | ( | char32_t | c | ) |
- Returns
- true if given code index represents whitespace
◆ isctrl()
| bool isctrl | ( | char32_t | c | ) |
- Returns
- true if given code index represents a control character
◆ isdigit()
| bool isdigit | ( | char32_t | c | ) |
- Returns
- true if given code index represents a numeric digit
◆ isdouble()
| bool isdouble | ( | char32_t | c | ) |
- Returns
- true if given code index is double-wide
◆ isgraph()
| bool isgraph | ( | char32_t | c | ) |
- Returns
- true if given code index is graphics symbol
◆ islower()
| bool islower | ( | char32_t | c | ) |
- Returns
- true if given code index is lowercase
◆ isnotword()
| bool isnotword | ( | char32_t | c | ) |
- Returns
- true if given code index is graphics symbol
◆ isprint()
| bool isprint | ( | char32_t | c | ) |
- Returns
- true if given code index is printable
◆ ispunct()
| bool ispunct | ( | char32_t | c | ) |
- Returns
- true if given code index represents punctuation
◆ isspace()
| bool isspace | ( | char32_t | c | ) |
- Returns
- true if given code index represents whitespace
◆ isspace_punct()
| bool isspace_punct | ( | char32_t | c | ) |
- Returns
- true if given code index represents whitespace or punctuation
◆ isupper()
| bool isupper | ( | char32_t | c | ) |
- Returns
- true if given code index is uppercase
◆ isxdigit()
| bool isxdigit | ( | char32_t | c | ) |
- Returns
- true if given code index represents a hexadecimal digit
◆ tolower()
| char32_t tolower | ( | char32_t | c | ) |
Converts the given code index to its corresponding lowercase version
◆ totitle()
| char32_t totitle | ( | char32_t | c | ) |
Converts the given code index to its corresponding titlecase version
◆ toupper()
| char32_t toupper | ( | char32_t | c | ) |
Converts the given code index to its corresponding uppercase version
◆ ToUTF8()
| std::string ToUTF8 | ( | std::u32string_view | s | ) |
This function is optimized for performance.
