Function Documentation

contains()

bool contains	(	const std::vector< std::string > &	v,
		const std::string &	other
	)

Check if a vector contains an item.

Definition at line 45 of file helpers.hpp.

list_dir()

std::vector<std::string> list_dir	(	const std::string &	path,
		const std::string &	pattern = ".*"
	)

Return the list of files matching a pattern from a given directory.

Parameters

path	where to look for files
pattern	which pattern to match (regex needed)

Definition at line 132 of file helpers.hpp.

operator<<()

template<typename T >

std::ostream& operator<<	(	std::ostream &	os,
		const std::vector< T > &	v
	)

Display an std::vector object.

Definition at line 32 of file helpers.hpp.

parseString() [1/2]

template<typename T >

T parseString

(

const char *

txt

)

Parse a char* into a numeric value.

Template Parameters

T	the output type

Parameters

txt	the string to parse

Returns

T the value as a T type

Definition at line 227 of file helpers.hpp.

parseString() [2/2]

template<typename T >

T parseString

(

const std::string &

		const std::string &	delimiter
	)

Split string into bits according to a given delimiter.

Parameters

text	original string
delimiter	string to cut on

Returns

a vector of strings
