◆ convert() [5/9]

bool PLMD::Tools::convert	(	const std::string &	str,
		long int &	t
	)

static

◆ convert() [6/9]

bool PLMD::Tools::convert	(	const std::string &	str,
		unsigned &	t
	)

static

Convert a string to an unsigned int, reading it.

◆ convert() [7/9]

bool PLMD::Tools::convert	(	const std::string &	str,
		AtomNumber &	t
	)

static

Convert a string to a atom number, reading it.

◆ convert() [8/9]

bool PLMD::Tools::convert	(	const std::string &	str,
		std::string &	t
	)

static

Convert a string to a string (i.e. copy)

◆ convert() [9/9]

template<typename T >

void PLMD::Tools::convert	(	T	i,
		std::string &	str
	)

static

Convert anything into a string.

◆ convertToAny()

template<class T >

bool PLMD::Tools::convertToAny	(	const std::string &	str,
		T &	t
	)

staticprivate

class to convert a string to a generic type T

◆ convertToReal()

template<class T >

bool PLMD::Tools::convertToReal	(	const std::string &	str,
		T &	t
	)

staticprivate

class to convert a string to a real type T.

T should be either float, double, or long double

◆ extension()

std::string PLMD::Tools::extension ( const std::string & s )

static

Extract the extensions from a file name.

E.g.: extension("pippo.xyz")="xyz". It only returns extensions with a length between 1 and 4 E.g.: extension("pippo.12345")="" whereas extenion("pippo.1234")="1234"; It is also smart enough to detect "/", so that extension("pippo/.t")="" whereas extension("pippo/a.t")="t"

◆ fastpow()

double PLMD::Tools::fastpow	(	double	base,
		int	exp
	)

inlinestatic

Fast int power.

◆ findKeyword()

bool PLMD::Tools::findKeyword	(	const std::vector< std::string > &	line,
		const std::string &	key
	)

static

Find a keyword on the input line, just reporting if it exists or not.

◆ getKey()

bool PLMD::Tools::getKey	(	std::vector< std::string > &	line,
		const std::string &	key,
		std::string &	s,
		int	rep = `-1`
	)

static

Retrieve a key from a vector of options.

It finds a key starting with "key=" or equal to "key" and copy the part after the = on s. E.g.: line.push_back("aa=xx"); getKey(line,"aa",s); will set s="xx"

◆ getline()

bool PLMD::Tools::getline	(	FILE *	fp,
		std::string &	line
	)

static

Get a line from the file pointer ifile.

◆ getParsedLine()

bool PLMD::Tools::getParsedLine	(	IFile &	ifile,
		std::vector< std::string > &	line
	)

static

Get a parsed line from the file pointer ifile This function already takes care of joining continued lines and splitting the resulting line into an array of words.

◆ getWords()

vector< string > PLMD::Tools::getWords	(	const std::string &	line,
		const char *	sep = `NULL`,
		int *	parlevel = `NULL`,
		const char *	parenthesis = `"{"`
	)

static

Split the line in words using separators.

It also take into account parenthesis. Outer parenthesis found are removed from output, and the text between them is considered as a single word. Only the outer parenthesis are processed, to allow nesting them. parlevel, if not NULL, is increased or decreased according to the number of opened/closed parenthesis

◆ interpretLabel()

void PLMD::Tools::interpretLabel ( std::vector< std::string > & s )

static

interpret ":" syntax for labels

◆ interpretRanges()

void PLMD::Tools::interpretRanges ( std::vector< std::string > & s )

static

Interpret atom ranges.

◆ ls()

vector< string > PLMD::Tools::ls ( const std::string & d )

static

list files in a directory

◆ parse()

template<class T >

bool PLMD::Tools::parse	(	std::vector< std::string > &	line,
		const std::string &	key,
		T &	val,
		int	rep = `-1`
	)

static

Find a keyword on the input line, eventually deleting it, and saving its value to val.

◆ parseFlag()

bool PLMD::Tools::parseFlag	(	std::vector< std::string > &	line,
		const std::string &	key,
		bool &	val
	)

inlinestatic

Find a keyword without arguments on the input line.

◆ parseVector()

template<class T >

bool PLMD::Tools::parseVector	(	std::vector< std::string > &	line,
		const std::string &	key,
		std::vector< T > &	val,
		int	rep = `-1`
	)

static

Find a keyword on the input line, eventually deleting it, and saving its value to a vector.

◆ pbc()

double PLMD::Tools::pbc ( double x )

inlinestatic

Apply pbc for a unitary cell.

beware: this brings any number into a pbc that ranges from -0.5 to 0.5

◆ removeDuplicates()

template<typename T >

void PLMD::Tools::removeDuplicates ( std::vector< T > & vec )

static

Remove duplicates from a vector of type T.

◆ startWith()

bool PLMD::Tools::startWith	(	const std::string &	full,
		const std::string &	start
	)

static

Check if a string full starts with string start.

Same as full.find(start)==0

◆ stripLeadingAndTrailingBlanks()

void PLMD::Tools::stripLeadingAndTrailingBlanks ( std::string & str )

static

removes leading and trailing blanks from a string

◆ trim()

void PLMD::Tools::trim ( std::string & s )

static
