Detailed Description

Generate and return failed = .false. if the attempt to fetch the width (in characters) of the current shell terminal is successful.
Otherwise, return failed = .true. indicating the occurrence of an error.

This procedure utilizes shell-specific commands and environment variables to get the properties of the current terminal window.

Parameters

[in]

width

: The output scalar integer of default kind IK containing the width (in characters) of the current terminal windows, if and only if the width retrieval is successful.

Returns

failed : The output scalar logical of default kind LK. It is .true. if and only if an error occurs while fetching the requested property.

Possible calling interfaces ⛓

use pm_sysShell, only: isFailedGetShellWidth
use pm_kind, only: LK, IK
logical(LK) :: failed
integer(IK) :: width
 
failed = isFailedGetShellWidth(width)

Remarks

The procedures under discussion are impure.

Example usage ⛓

program example
 
    use pm_kind, only: LK, IK, SK
    use pm_io, only: display_type
    use pm_sysShell, only: isFailedGetShellWidth
 
    implicit none
 
    integer(IK) :: width
    logical(LK) :: failed
 
    type(display_type) :: disp
    disp = display_type(file = "main.out.F90")
 
    call disp%skip()
    call disp%show(.not.'if ( isFailedGetShellWidth(width)) call disp%show(width)')
                    if (.not. isFailedGetShellWidth(width)) call disp%show(width)
    call disp%skip()

Example Unix compile command via Intel ifort compiler ⛓

#!/usr/bin/env sh
rm main.exe
ifort -fpp -standard-semantics -O3 -Wl,-rpath,../../../lib -I../../../inc main.F90 ../../../lib/libparamonte* -o main.exe
./main.exe

Example Windows Batch compile command via Intel ifort compiler ⛓

del main.exe
set PATH=..\..\..\lib;%PATH%
ifort /fpp /standard-semantics /O3 /I:..\..\..\include main.F90 ..\..\..\lib\libparamonte*.lib /exe:main.exe
main.exe

Example Unix / MinGW compile command via GNU gfortran compiler ⛓

#!/usr/bin/env sh
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 ⛓

 
if (.not. isFailedGetShellWidth(width)) call disp%show(width)
+208
 
 

Test:

test_pm_sysShell

Todo:

Low Priority: The current Fortran standard 202x does not allow passing characters of non-default kind to Fortran intrinsic procedures.
This generic interface should be extended to in the future to support non-default character kinds when they fully supported by the Fortran intrinsic procedures.
