Path types.

Enumerator
path_type_file 

Native file system path. (On windows, '/' are turned into '\'. On linux, '\' are turned into '/')

path_type_virtual

PathType  path_type = path_type_file 
)
static

Create a fullname from parts.

Returns
The full name
static CL_String CL_PathHelp::get_fullname ( const CL_String fullpath,
const CL_String filename,
const CL_String extension,
PathType  path_type = path_type_file 
)
static

Create a fullname from parts.

param: fullpath = The full path to use param: filename = The filename to use param: extension = The filename extension to use param: path_type = The path type

Returns
The full name
static CL_String CL_PathHelp::get_fullname ( const CL_String location,
const CL_String basepath,
const CL_String filename,
const CL_String extension,
PathType  path_type = path_type_file 
)
static

Create a fullname from parts.

param: location = The location to use param: fullpath = The full path to use param: filename = The filename to use param: extension = The filename extension to use param: path_type = The path type

Returns
The full name
static CL_String CL_PathHelp::get_fullpath ( const CL_String fullname,
PathType  path_type = path_type_file 
)
static

Returns the path including the location.

param: fullname = The full path to use (including filename) param: path_type = The path type

Returns
The full path including the location (excluding filename)
* static CL_String CL_PathHelp::get_location ( const CL_String fullname,
PathType  path_type = path_type_file 
)
static

Returns the drive (C:) or share name ( \ \ computer \ share)

If (path_type == path_type_virtual) or not using windows, then this function always returns an empty string.

Parameters
fullnameThe full path name to use
path_typeThe path type
Returns
The drive or share name
static bool CL_PathHelp::is_absolute ( const CL_String path,
PathType  path_type = path_type_file 
)
static

Check if a path is absolute.

Parameters
pathThe path to check
path_typeThe path type (of path)
Returns
true if path is absolute
static bool CL_PathHelp::is_relative ( const CL_String path,
PathType  path_type = path_type_file 
)
static

Check if a path is relative.

Parameters
pathThe path to check
path_typeThe path type (of path)
Returns
true if path is relative
static CL_String CL_PathHelp::make_absolute ( const CL_String base_path,
const CL_String relative_path,
PathType  path_type = path_type_file 
)
static

Convert a relative path to an absolute path.

Parameters
base_pathThe base path (Does not require a trailing slash)
relative_pathThe relative path
path_typeThe path type
Returns
The converted path

This function behaves differently depending on OS and path_type. In Windows, if the relative_path begins with a drive letter, and the driver letter differs from the base path, the path is converted to an absolute path using the current directory for that drive. Likewise, if the specified base path does not include a drive or its path is not absolute, the current drive and directory is added. The function converts all slashes to backslashes.

If the OS is unix based, there is no location (drive or share name) and the function also converts all backslashes to slashes.

If the type is path_type_virtual, the base path is required to be absolute. If it does not start in a slash, the function prefixes a slash to the path. The current drive or directory is never taken into account and all backslashes are converted to slashes.

This function calls normalise() on base_path and relative_path.

Example #1:

CL_String str = CL_PathHelp::make_absolute("ABD/DEF/", "GFX/Filename.txt", CL_PathHelp::path_type_file);
On Linux: str = "/home/user/ABD/DEF/GFX/Filename.txt"
On Windows: str = "c:\user\ABD\DEF\GFX\Filename.txt"

Example #2:

CL_String str = CL_PathHelp::make_absolute("/ABD/DEF/", "../Filename.txt", CL_PathHelp::path_type_file);
On Linux: str = "/ABD/Filename.txt"
On Windows: str = "c:\ABD\Filename.txt"

Example #3:

On Linux: str = "/ABD/Filename.txt"
On Windows: str = "/ABD/Filename.txt"
static CL_String CL_PathHelp::make_relative ( const CL_String base_path,
const CL_String absolute_path,
PathType  path_type = path_type_file 
)
static

Converts an absolute path into a path relative to a base path.

Parameters
base_pathThe base path (Does not require a trailing slash)
absolute_pathThe absolute path
path_typeThe path type
Returns
The converted path

This function is the inverse of CL_FileHelp::make_absolute. Please see the detailed information for make_absolute for more information about behavior.

This function calls normalise() on the base_path and absolute_path-

Example #1 (Windows):

CL_String str = CL_PathHelp::make_relative("ABD/DEF/", "c:\user\ABD\Filename.txt", CL_PathHelp::path_type_file);
On Windows: str = "..\Filename.txt"
static CL_String CL_PathHelp::normalize ( const CL_String path,
PathType  path_type = path_type_file 
)
static

Normalize a path.

Parameters
pathThe path to use
path_typeThe path type (of the normalized path)
Returns
The converted path

Converts all slashes and backslashes into their right type. Simplifies or removes all . and .., converting the path into its most readable form.

static CL_String CL_PathHelp::remove_trailing_slash ( const CL_String path)
static

Remove trailing slash or backslash from path.

This function checks if a path has a trailing slash/backslash and removes it if needed.

Parameters
pathThe path to use
Returns
The converted path
static std::vector<CL_String> CL_PathHelp::split_basepath ( const CL_String fullname,
PathType  path_type = path_type_file 
)
static

Splits the path, excluding the location, into parts.

param: fullname = The full path name to use param: path_type = The path type

Returns
The split path
