Generate and return a path quoted with single or double quotation marks whose metacharacters are also properly escaped depending on the runtime system shell.
More...
Generate and return a path quoted with single or double quotation marks whose metacharacters are also properly escaped depending on the runtime system shell.
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 procedures under this generic interface call one of the following generic interfaces, depending on the specified or determined runtime system shell,
- getPathVerbatimPowerShell in Windows or Unix PowerShell environments.
- getPathVerbatimPosix in POSIX-compliant shell environments.
- getPathVerbatimCMD in Windows CMD shell environments.
- Parameters
-
[in] | path | : The input scalar character of default kind SK containing the path to be enclosed with quotation marks.
|
[out] | failed | : The output scalar logical of default kind LK that is .true. if and only if an error occurs while inferring the runtime system shell.
(optional. If missing and a runtime error occurs, the program will halt by calling error stop .) |
[in,out] | errmsg | : The input/output scalar character of default kind SK of arbitrary length type parameter.
If an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error.
A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full.
(optional. If missing, no error message will be output. Its presence is relevant only if failed is also present.) |
- Returns
pathVerbatim
: The output allocatable
scalar of type character
of the same kind as path
containing the modified input path
enclosed with single or double quotation marks such that it can be treated as a verbatim path in the specified or the runtime shell.
Possible calling interfaces ⛓
character(255, SK) :: errmsg
logical(LK) :: failed

- Test:
- test_pm_sysPath
- Todo:
- High Priority: The current Fortran standard 202x does not allow passing characters of non-default kind to the intrinsic Fortran statements and procedures.
As such, the implementation of this procedure for non-default character
kinds leads to compile-time kind mismatch errors.
This procedure should be converted back to a generic interface in the future when non-default character kinds are also fully supported by the intrinsic functions.
