Detailed Description

Generate and return a path quoted with single quotation marks where all instances of single quotes \(\ms{'}\) within the path are replaced with \(\ms{''}\).

This procedure exists to minimize security vulnerabilities associated with paths that may contain harmful system commands.
To ensure paths are interpreted as simple strings, they must be quoted with proper quotation marks on both Windows and Unix-like platforms.
The path returned by this procedure is as close as one can get to a verbatim path in Windows PowerShell or PowerShell Core on Unix platforms.
If a path is be used in a call to a PowerShell runtime shell, it is recommended to pass it to this procedure to ensure the path is quoted and all instances of dangling quotation marks \(\ms{'}\) are gracefully escaped.

Parameters

[in]

path

: The input scalar character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) containing the path to be enclosed with quotation marks.

Returns

pathVerbatim : The output allocatable scalar of type character of the same kind as path containing the modified input path enclosed with single quotation marks where all instances of single quotation marks within the path are escaped.

Possible calling interfaces ⛓

use pm_sysPath, only: getPathVerbatimPowerShell
 
pathVerbatim = getPathVerbatimPowerShell(path)

Warning

Note that this procedure does not inspect the input path for the presence of other illegal Windows reserved characters on Windows platforms (e.g., WINDOWS_RESERVED_STR).
The presence of illegal characters in a Windows path can lead to runtime errors even if the path is quoted by the procedures of this generic interface.

The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds. The impurity is caused by the call to procedures whose purity depends on the library build configuration.
