NAME
SDL2::filesystem - Filesystem SDL API Functions
SYNOPSIS
use SDL2 qw[:filesystem];DESCRIPTION
SDL2::filesystem provides functions to deal with the filesystem.
Functions
These may be imported by name or with the :filesystem tag.
SDL_GetBasePath( )
Get the directory where the application was run from.
This is not necessarily a fast call, so you should call this once near startup and save the string if you need it.
Mac OS X and iOS Specific Functionality: If the application is in a ".app" bundle, this function returns the Resource directory (e.g. MyApp.app/Contents/Resources/). This behaviour can be overridden by adding a property to the Info.plist file. Adding a string key with the name SDL_FILESYSTEM_BASE_DIR_TYPE with a supported value will change the behaviour.
Supported values for the SDL_FILESYSTEM_BASE_DIR_TYPE property (Given an application in /Applications/SDLApp/MyApp.app):
resource: bundle resource directory (the default). For example:/Applications/SDLApp/MyApp.app/Contents/Resourcesbundle: the Bundle directory. For example:/Applications/SDLApp/MyApp.app/parent: the containing directory of the bundle. For example:/Applications/SDLApp/
The returned path is guaranteed to end with a path separator (\ on Windows, / on most other platforms).
The pointer returned is owned by the caller. Please call SDL_free() on the pointer when done with it.
Returns an absolute path in UTF-8 encoding to the application data directory. undef will be returned on error or when the platform doesn't implement this functionality, call SDL_GetError( ) for more information.
( ... )
Get the user-and-app-specific path where files can be written.
Get the "pref dir". This is meant to be where users can write personal files (preferences and save games, etc) that are specific to your application. This directory is unique per user, per application.
This function will decide the appropriate location in the native filesystem, create the directory if necessary, and return a string of the absolute path to the directory in UTF-8 encoding.
On Windows, the string might look like: C:\Users\bob\AppData\Roaming\My Company\My Program Name\
On Linux, the string might look like: /home/bob/.local/share/My Program Name/
On Mac OS X, the string might look like: /Users/bob/Library/Application Support/My Program Name/
You should assume the path returned by this function is the only safe place to write files (and that SDL_GetBasePath( ), while it might be writable, or even the parent of the returned path, isn't where you should be writing things).
Both the org and app strings may become part of a directory name, so please follow these rules:
- - Try to use the same org string (_including case-sensitivity_) for all your applications that use this function.
- - Always use a unique app string for each one, and make sure it never changes for an app once you've decided on it.
- - Unicode characters are legal, as long as it's UTF-8 encoded, but...
- - ...only use letters, numbers, and spaces. Avoid punctuation like "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
The returned path is guaranteed to end with a path separator (\ on Windows, / on most other platforms).
The pointer returned is owned by the caller. Please call SDL_free( ... ) on the pointer when done with it.
Expected parameters include:
Returns a UTF-8 string of the user directory in platform-dependent notation. undef if there's a problem (creating directory failed, etc.).
