Detailed Description

Generate and return the number of non-overlapping repetitions of the input pattern in the input str until the first occurrence of a mismatch between pattern and the relevant segment of str.

The procedures under this generic interface are meant to be used primarily within the wrapping procedures in the parent module.
The procedures under this generic interface count the number (countPattern) of non-overlapping repetitions of the input pattern at the beginning of the input str. The returned result the length of the indentation at the beginning of str, in units of len(pattern).

Parameters

[in]	str	: The input scalar of type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) whose initial indentation is to be found.
[in]	pattern	: The input scalar of the same type and kind as the input str of arbitrary length type parameter. It represents the building block of the potential indentation (at the beginning of the input str) whose length is to be found.

Returns

lenIndent : The output scalar integer of default kind IK, representing the length of the indentation identified at the beginning of the input str, in units of len(pattern).

Possible calling interfaces ⛓

use pm_str, only: getLenIndent
integer(IK) :: lenIndent
 
lenIndent = getLenIndent(str, pattern)

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.

Warning

If the input str or pattern has a zero length or len(str) < len(pattern), the returned result is 0.

Example usage ⛓

program example
 
    use pm_kind, only: IK, LK
    use pm_kind, only: SK ! All kinds are supported.
    use pm_str, only: getLenIndent
    use pm_io, only: display_type
    use pm_strASCII, only: LF ! linefeed for better display
 
    implicit none
 
    character(:, SK), allocatable   :: str
 
    type(display_type) :: disp
 
    disp = display_type(file = "main.out.F90")
 
    str = ".-+.-+ParaMonte"
 
    call disp%show("str")
    call disp%show( str, deliml = SK_"""" )
    call disp%show("getLenIndent(str, SK_'.-+')")
    call disp%show( getLenIndent(str, SK_'.-+') )
    call disp%skip()
 
    str = "ParaMonte"
 
    call disp%show("str")
    call disp%show( str, deliml = SK_"""" )
    call disp%show("getLenIndent(str, SK_'.-+')")
    call disp%show( getLenIndent(str, SK_'.-+') )
    call disp%skip()
 
    call disp%show("getLenIndent([character(50,SK) :: 'ParaMonte', ' ParaMonte', '  ParaMonte'], SK_'  ')")
    call disp%show( getLenIndent([character(50,SK) :: 'ParaMonte', ' ParaMonte', '  ParaMonte'], SK_'  ') )
    call disp%skip()
 
end program example

rm main.exe
gfortran -cpp -ffree-line-length-none -O3 -Wl,-rpath,../../../lib -I../../../inc main.F90 ../../../lib/libparamonte* -o main.exe
./main.exe

Example output ⛓

str
".-+.-+ParaMonte"
getLenIndent(str, SK_'.-+')
+2
 
str
