Detailed Description

Some useful string operations.

Function Documentation

◆ ToString()

template<class T>

std::string StrUtils::ToString	(	T	value,
		bool *	ok = nullptr )

Converts a value to string.

If given, ok is set to true/false on success/failure. Warning: To avoid unnecessary problems, always give full template qualifier e.g. ToString<int>

◆ FromString()

template<class T>

T StrUtils::FromString	(	const std::string &	str,
		bool *	ok = nullptr )

Converts a value to string.

If given, ok is set to true/false on success/failure. Warning: To avoid unnecessary problems, always give full template qualifier e.g. FromString<int>

◆ HexStringToInt()

unsigned int StrUtils::HexStringToInt ( const std::string & str )

Converts string of hex characters to int.

◆ Format()

std::string StrUtils::Format	(	const char *	fmt,
			... )

Replacement for sprintf().

◆ Replace()

std::string StrUtils::Replace	(	const std::string &	str,
		const std::string &	oldStr,
		const std::string &	newStr )

Returns a string with every occurence of oldStr in str replaced to newStr.

◆ UnicodeCharToUtf8()

std::string StrUtils::UnicodeCharToUtf8 ( unsigned int ch )

Converts a wide Unicode char to a single UTF-8 encoded char.

◆ UnicodeStringToUtf8()

std::string StrUtils::UnicodeStringToUtf8 ( const std::wstring & str )

Converts a wide Unicode string to a UTF-8 encoded string.

◆ Utf8CharToUnicode()

unsigned int StrUtils::Utf8CharToUnicode ( const std::string & ch )

Converts a UTF-8 encoded single character to wide Unicode char.

◆ Utf8StringToUnicode()

std::wstring StrUtils::Utf8StringToUnicode ( const std::string & str )

Converts a UTF-8 encoded string to wide Unicode string.

◆ Utf8CharSizeAt()

int StrUtils::Utf8CharSizeAt	(	const std::string &	str,
		unsigned int	pos )

Returns the size in bytes of UTF-8 character at given pos in a UTF-8 str.

◆ Utf8StringLength()

std::size_t StrUtils::Utf8StringLength ( const std::string & str )

Returns the length in characters of UTF-8 string str.

◆ isUtf8ContinuationByte()

bool StrUtils::isUtf8ContinuationByte ( char c )

Returns true if char is continuation UTF-8 byte.
