Function Documentation

concatpath()

std::string utils::concatpath	(	const std::string &	left,
		const std::string &	right
	)

Take 2 strings and concatenate them and make sure there is a directory separator (/) between them.

This function doesn't care whether or not the values given as parameters are valid path strings. It is the responsibility of the user to make sure that the values given are valid path strings. The function only guarantees that the output string is a valid path string.

Parameters

left	The left hand side of the result string
right	The right hand side of the result string

Returns

string

dirname()

std::string utils::dirname

(

const std::string &

path

)

Get the directory name of the path.

Parameters

path	The path to use.

Returns

string

mkpath()

bool utils::mkpath	(	std::string	path,
		int	mode = 0777
	)

Make path given.

This tries to be the equivalent to "mkdir -p" and creates a new directory whenever it needs to.

Parameters

path	The path to be created
mode	The mode/permissions for all the new directories

Returns

bool Success/Fail

scientific_format() [1/2]

std::string utils::scientific_format	(	const std::vector< double > &	v,
		int	width = 20,
		int	prec = 10
	)

Turns a vector of doubles into a string written in scientific format.

The code is stolen from https://github.com/anderkve/FYS3150.

Parameters

v	The vector to stringify
width	The reserved width of the string
prec	The precision of the stringified number

Returns

std::string

scientific_format() [2/2]

std::string utils::scientific_format	(	double	d,
		int	width = 20,
		int	prec = 10
	)

The code is stolen from https://github.com/anderkve/FYS3150.

Parameters

d	The number to stringify
width	The reserved width of the string
