%Docstring
|
|
Returns a list of the extensions contained within a file ``filter``
|
|
string. E.g. a ``filter`` of ``GeoTIFF Files (*.tiff *.tif)`` would
|
|
return a list containing ``tiff``, ``tif``. The initial '.' is stripped
|
|
off the extension.

extracts the wildcard portion of this filter (i.e. ``*.tiff *.tif``).

static bool fileMatchesFilter( const QString &fileName, const QString &filter );

%Docstring
|

Returns ``True`` if the given ``fileName`` matches a file ``filter``
|
|
string.
|
|
|
|
E.g a filter of ``GeoTIFF Files (*.tiff *.tif)`` would return ``True``
|
|
for a ``fileName`` of ``/home/test.tif``, or ``False`` for
|
|
``/home/test.jpg``.

%Docstring
|
|
Ensures that a ``fileName`` ends with an extension from the provided
|
|
list of ``extensions``.
|
|
|
|
E.g. if extensions contains ``tif`` and ``tiff``, then a ``fileName`` of
|
|
``d:/my_file`` will return ``d:/my_file.tif``. A ``fileName`` of
|
|
``d:/my_file.TIFF`` or ``d:/my_file.TIF`` will be returned unchanged.

|

%Docstring
|
|
Ensures that a ``fileName`` ends with an extension from the specified
|
|
``filter`` string.
|
|
|
|
E.g. a ``fileName`` of ``d:/my_file`` with a filter of ``GeoTIFF Files
|
|
(*.tiff *.tif)`` will return ``d:/my_file.tif``, where as ``fileName``
|
|
of ``d:/my_file.TIFF`` or ``d:/my_file.TIF`` will be returned unchanged.

|
|
Converts a ``string`` to a safe filename, replacing characters which are
|
|
not safe for filenames with an '_' character.
|
|
|
|
.. warning::
|
|
|
|
This method strips slashes from the filename, so it is safe to call with file names only, not complete paths.

static QString findClosestExistingPath( const QString &path );
|
|
%Docstring
|

Returns the top-most existing folder from ``path``. E.g. if ``path`` is
|
|
``/home/user/projects/2018/P4343`` and ``/home/user/projects`` exists
|
|
but no ``2018`` subfolder exists, then the function will return

``/home/user/projects``.

|

Will check ``basepath`` in an outward spiral up to ``maxClimbs`` levels
|
|
to check if ``file`` exists.
|
|
|
|
:param file: Name or full path of the file to find
|
|
:param basepath: current basepath of the file, needed if only the name
|
|
is specified in file
|
|
:param maxClimbs: limit the number of time the search can move up from
|
|
the basepath
|
|
:param searchCeiling: limits where in the folder hierarchy the search
|
|
can be performed, 1 = root/drive, 2 = first folder
|
|
level, 3 = sub folders ( Unix: /usr/bin, Win:
|
|
C:/Users/Admin ), etc.
|
|
:param currentDir: alternative default directory to override the actual
|
|
current directory during the search
|

Returns the drive type for the given ``path``.

supported on the current platform.

Returns ``True`` if the specified ``path`` is assumed to reside on a

slow device, e.g. a remote network drive or other non-fixed device.

static QSet< QString > sidecarFilesForPath( const QString &path );
|
|
%Docstring
|
|
Returns a list of the sidecar files which exist for the dataset a the
|
|
specified ``path``.
|
|
|
|
In this context a sidecar file is defined as a file which shares the
|
|
same base filename as a dataset, but which differs in file extension. It
|
|
defines the list of additional files which must be renamed or deleted
|
|
alongside the main file associated with the dataset in order to
|
|
completely rename/delete the dataset.
|
|
|
|
For instance, if ``path`` specified a .shp file then the corresponding
|
|
.dbf, .idx and .prj files would be returned (amongst others).
|
|
|
|
.. note::
|
|
|
|
QGIS metadata files (.qmd) and map layer styling files (.qml) are NOT included
|
|
in the returned list.

|
|
%Docstring
|
|
Renames the dataset at ``oldPath`` to ``newPath``, renaming both the
|
|
file at ``oldPath`` and all associated sidecar files which exist for it.
|
|
|
|
For instance, if ``oldPath`` specified a .shp file then the
|
|
corresponding .dbf, .idx and .prj files would be renamed (amongst
|
|
others).
|
|
|
|
The destination directory must already exist.
|
|
|
|
The optional ``flags`` argument can be used to control whether QMD
|
|
metadata files and QML styling files should also be renamed accordingly.
|
|
By default these will be renamed, but manually specifying a different
|
|
set of flags allows callers to avoid this when desired.
|
|
|
|
:param oldPath: original path to dataset
|
|
:param newPath: new path for dataset
|
|
:param flags: optional flags to control file operation behavior
|
|
|
|
:return: - ``True`` if the dataset was successfully renamed, or
|
|
``False`` if an error occurred
|
|
- error: a descriptive error message if the rename operation
|
|
fails

static QStringList splitPathToComponents( const QString &path );
|
|
%Docstring
|
|
Given a file ``path``, returns a list of all the components leading to
|
|
that path.
|
|
|
|
E.g. if ``path`` is ``/home/user/Pictures/test.png``, the returned list
|
|
will contain ``/`` , ``home``, ``user``, ``Pictures``, ``test.png``.

static QString uniquePath( const QString &path );
|
|
%Docstring
|
|
Creates a unique file path name from a desired path by appending
|
|
``_<n>`` (where ``<n>`` is an integer number) before the file suffix.
|
|
|
|
E.g. if ``/path/my_image.png`` already exists ``/path/my_image_2.png``
|
|
(and ``_3`, ``_4`` etc.) will be checked until a file path that does not
|
|
already exist is found.
|
|
|
|
:param path: the desired path.
|
|
|
|
:return: the unmodified path if path is already unique or the new path
|
|
with ``_<n>`` (where ``<n>`` is an integer number) appended to
|
|
the file name before the suffix.
|
|
|
|
.. note::
|
|
|
|
This function does not make any check on path validity and write permissions.
