Detailed Description

Codes for dealing with string processing.

Function Documentation

emptystr()

TECA_EXPORT std::string teca_string_util::emptystr ( const std::string &  in )

inline

When passed the string "" return empty string otherwise return the passed string.

extract_string()

TECA_EXPORT int teca_string_util::extract_string	(	const char *	istr,
		std::string &	field
	)

Convert the characters between the first and second double quote to a std::string. Escaped characters are skipped. Return 0 if successful.

extract_value()

template<typename val_t >

TECA_EXPORT int teca_string_util::extract_value	(	char *	l,
		val_t &	val
	)

Extract the value in a "name = value" pair. an error occurs if splitting the input on '=' doesn't produce 2 tokens or if the conversion to val_t fails. returns 0 if successful.

is_comment()

int teca_string_util::is_comment ( char *  buf )

inline

return 0 if the first non-pad character is #

remove_postfix()

TECA_EXPORT void teca_string_util::remove_postfix	(	std::set< std::string > &	names,
		std::string	postfix
	)

Given a collection of strings, where some of the strings end with a common substring, the post-fix, this function visits each string in the collection and removes the post-fix from each string that it is found in.

skip_pad()

int teca_string_util::skip_pad ( char *&  buf )

inline

Skip space, tabs, and new lines. return non-zero if the end of the string is reached before a non-pad character is encountered

tokenize() [1/2]

template<typename container_t = std::vector<char*>>

TECA_EXPORT int teca_string_util::tokenize	(	char *	istr,
		char	delim,
		container_t &	ostr
	)

Scan the input string (istr) for the given a delimiter (delim). push a point to the first non-delimiter character and the first character after each instance of the delimiter. return zero if successful. when successful there will be at least one value.

tokenize() [2/2]

TECA_EXPORT int teca_string_util::tokenize	(	char *	istr,
		char	delim,
		int	n_cols,
		char **	ostr
	)

Scan the input string (istr) for the given a delimiter (delim). push a pointer to the first non-delimiter character and the first character after each instance of the delimiter. return zero if successful. when successful there will be at least one value.
