Interfaces

count

Overload intrinsic function count for counting substring occurences into strings.

Module procedures: count_substring

Subroutines

tokenize

Tokenize a string in order to parse it.

@note The dummy array containing tokens must allocatable and its character elements must have the same length of the input string. If the length of the delimiter is higher than the input string one then the output tokens array is allocated with only one element set to input string.

Attributes: pure

subroutine tokenize(strin, delimiter, toks, Nt)

Arguments

Name	Type	Intent	Attributes	Description
strin	character(len=*)	in		String to be tokenized.
delimiter	character(len=*)	in		Delimiter of tokens.
toks	character(len=len)	out	allocatable	Tokens.
Nt	integer(kind=I4P)	out	optional	Number of tokens.

Functions

count_substring

Count the number of occurences of a substring into a string.

Attributes: elemental

Returns: integer(kind=I4P)

function count_substring(string, substring) result(No)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String.
substring	character(len=*)	in		Substring.

replace

Replace substring (only first occurrence) into a string.

Attributes: pure

Returns: character(len=:)

function replace(string, substring, restring) result(newstring)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String to be modified.
substring	character(len=*)	in		Substring to be replaced.
restring	character(len=*)	in		String to be inserted.

Call graph

replace_all

Replace substring (all occurrences) into a string.

@note Leading and trailing white spaces are stripped out.

Attributes: pure

Returns: character(len=:)

function replace_all(string, substring, restring) result(newstring)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String to be modified.
substring	character(len=*)	in		Substring to be replaced.
restring	character(len=*)	in		String to be inserted.

Call graph

unique

Reduce to one (unique) multiple (sequential) occurrences of a characters substring into a string.

For example the string ' ab-cre-cre-ab' is reduce to 'ab-cre-ab' if the substring is '-cre'. @note Eventual multiple trailing white space are not reduced to one occurrence.

Attributes: elemental

Returns: character(len=len)

function unique(string, substring) result(uniq)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String to be parsed.
substring	character(len=*)	in		Substring which multiple occurences must be reduced to one.

Call graph

upper_case

Convert the lower case characters of a string to upper case one.

Attributes: elemental

Returns: character(len=len)

function upper_case(string)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String to be converted.

Call graph

wstrip

Strip out leading and trailing white spaces from a string.

Attributes: pure

Returns: character(len=:)

function wstrip(string) result(newstring)

Arguments

Name	Type	Intent	Attributes	Description
string	character(len=*)	in		String to be modified.
