Detailed Description

Return a POSIX-standard (Unix-like) path from the input (Windows-style) path.

See the note below on how an input POSIX-style pathis handled.
The path nomalization by this procedure is specifically done by

  1. replacing all instances of the Windows-style path-separator (\) in the input path with the POSIX-style path-separator (/), and
  2. collapsing all redundant directory separators such that \A//B\/, ///A/B\\, \A//B\ all become /A/B.
  3. If the path begins with two directory separators, it is interpreted as a UNC path and the initial hostname portion of the path remains untouched.
  4. Additionally, if ignore is present, then all instances of the pattern ignore will be copied to the output path as is.
    For example,
    1. if the input path contains a Hex value \xhh, then set ignore = \xhh or
    2. if the is already (partially) POSIX-compliant such that \ should be interprested verbatim then ignore can be set to \.
Parameters
[in,out]path: The input/output allocatable scalar character of default kind SK.
On input, it contains the Windows-style path to be converted to the POSIX-style.
On output, it is reallocated to contain the converted POSIX-style path.
On output, all instances of the backslash are replaced with forward-slash.
[in]ignore: The input scalar character of the same kind as path of arbitrary length type parameter.
If present, any pattern matching the value of ignore from left to right will be interpreted verbatim and copied to the output path as is.
(optional, default = "")


Possible calling interfaces ⛓

use pm_sysPath, only: setPathPosix
character(:, SK), allocatable :: path
call setPathPosix(path)
call setPathPosix(path, ignore = ignore)
pm_sysPath::setPathPosix
Return a POSIX-standard (Unix-like) path from the input (Windows-style) path.
Definition: pm_sysPath.F90:1726
pm_sysPath
This module contains classes and procedures for manipulating system file/folder paths.
Definition: pm_sysPath.F90:274
Warning
Any escape character \ is interpreted as a Windows-style directory separator by the procedures of this generic interface and will be converted to POSIX-style directory separator character /.
Therefore, passing an already POSIX-compliant path to the procedures of this generic interface is fine as long as,
  1. no POSIX special character is escaped via the POSIX escape character \ in the input path, and
  2. no backward slash \ appears in the path unless it serves as a directory separator or ignore ="\"`.
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 dependency on setInserted.
Note that no trimming of the input path is performed by the procedure.
Consequently, any leading or trailing whitespace characters will be significant.
Remarks
This procedure has the same functionality as its functional equivalent getPathPosix except for the fact it can be slightly faster than the functional procedure.
Note
The procedure setPathPosixEscaped can be called if any Bash environment special characters as specified in POSIX_RESERVED_STR need to be escaped in the output path via the escape character \.
Otherwise, getPathVerbatimPosix can generate a path whose characters will be interpreted verbatim in POSIX shell environment.

High Priority: An optional argument external procedure iseq() should be added to the procedures of this generic interface to bring flexibility to searching for ignore patterns.
