Function Documentation

rmfile()

function rmfile	(	in	file,
		in	desc
	)

Return a scalar MATLAB logical that is true if and only if the deletion of the input file fails, otherwise, return false.

This function is a simple wrapper around the MATLAB function delete().
It is primarily meant to bring consistency to messaging file deletions if they fail.
Such consistency is particularly required on Windows systems as the OS tends to lock file ownership to one application causing deletions to fail frequently.

Parameters

[in]	file	: The input scalar MATLAB string, containing the file path to be deleted.
[in]	desc	: The input scalar MATLAB string, containing a descriptive message to be printed on the MATLAB command line if the deletion task fails. The input desc, if not empty, will be added to the following template before being displayed: "Failed to delete <desc> from the local disk. File may be protected."<br> If the input desc is empty [] or empty string "", a default value "the requested file" for desc will be added to the template. (optional. If missing, no warning will be displayed upon failure.)

Returns

failed : The output scalar MATLAB logical that is true if and only if the deletion of the input file fails, otherwise, return false.

Possible calling interfaces ⛓

failed = pm.sys.path.rmfile(file)
failed = pm.sys.path.rmfile(file, desc)

Example usage ⛓

cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.
addpath('../../../../'); % Add the ParaMonte library root directory to the search path.
 
pm.matlab.show()
pm.matlab.show("fid = fopen('temp.temp', 'w'); fclose(fid);")
                fid = fopen('temp.temp', 'w'); fclose(fid);
 
pm.matlab.show()
pm.matlab.show('pm.sys.path.list()')
pm.matlab.show( pm.sys.path.list() )
 
pm.matlab.show()
pm.matlab.show('pm.sys.path.rmfile("temp.temp")')
pm.matlab.show( pm.sys.path.rmfile("temp.temp") )
 
pm.matlab.show()
pm.matlab.show('pm.sys.path.rmfile("temp.temp")')
pm.matlab.show( pm.sys.path.rmfile("temp.temp") )
 
pm.matlab.show()
pm.matlab.show('pm.sys.path.rmfile("temp.temp", "Temp file is missing.")')
pm.matlab.show( pm.sys.path.rmfile("temp.temp", "Temp file is missing.") )
 
pm.matlab.show()
pm.matlab.show('pm.sys.path.list()')
pm.matlab.show( pm.sys.path.list() )

Example output ⛓

 
fid = fopen('temp.temp', 'w'); fclose(fid);
 
pm.sys.path.list()
    "main.m"
    "main.out.m"
    "temp.temp"
 
pm.sys.path.rmfile("temp.temp")
   0
 
pm.sys.path.rmfile("temp.temp")

pm.sys.path.rmfile("temp.temp", "Temp file is missing.")
