AppDirs
=======
## Overview
__AppDirs__ is a small java library which provides a path to the platform dependent special folder/directory.
For example, here are the common paths of the folder/directory that is used to store application specific user data on each platform.
On Mac OS X : ```/Users//Library/Application Support/```
On Windows XP : ```C:\Documents and Settings\\Application Data\Local Settings\\```
On Windows 7 : ```C:\Users\\AppData\\```
On Unix/Linux : ```/home//.local/share/```
With __AppDirs__, you can get the path depending on the runtime platform with the following code.
``` java
AppDirs appDirs = AppDirsFactory.getInstance();
appDirs.getUserDataDir("", null, "");
```
__AppDirs__ is loosely based on [a python module](https://github.com/ActiveState/appdirs) with the same name.
Please use the issue tracker for bug reports or suggestions.
## Requirements
__AppDirs__ requires Java SE 6 or later and [Java Native Access (JNA)](https://github.com/twall/jna) as its dependency.
## Quickstart
### With a dependency management tool ([Maven](https://maven.apache.org/), [Gradle](https://gradle.org/), etc.)
1. Choose the latest version on the [MvnRepository](https://mvnrepository.com/artifact/net.harawata/appdirs).
2. From the tabs of dependency management tools, select the one you are using.
3. Copy the snippet and add it to the dependency list of your project file (`pom.xml`, `build.gradle`, etc.).
### Without a dependency management tool
1. Choose the latest version on the [release page](https://github.com/harawata/appdirs/releases).
2. Download the `appdirs-(version).jar` file.
3. You may also need to download [`jna-(version).jar`](https://mvnrepository.com/artifact/net.java.dev.jna/jna) and [`jna-platform-(version).jar`](https://mvnrepository.com/artifact/net.java.dev.jna/jna-platform).
4. Put all .jar files into the classpath of your application.
## Supported directories
Currently, __AppDirs__ has the following methods.
- getUserDataDir
- getUserConfigDir
- getUserCacheDir
- getUserLogDir
- getUserDownloadsDir (since 1.2.2)
- getSiteDataDir
- getSiteConfigDir
- getSharedDir (since 1.1.0)
Here is a test program and the output on some platforms.
```java
import net.harawata.appdirs.AppDirs;
import net.harawata.appdirs.AppDirsFactory;
public class AppDirTest {
public static void main(String[] args) {
AppDirs appDirs = AppDirsFactory.getInstance();
System.out.println("User data dir: " + appDirs.getUserDataDir("myapp", "1.2.3", "harawata"));
System.out.println("User data dir (roaming): "
+ appDirs.getUserDataDir("myapp", "1.2.3", "harawata", true));
System.out.println("User config dir: "
+ appDirs.getUserConfigDir("myapp", "1.2.3", "harawata"));
System.out.println("User config dir (roaming): "
+ appDirs.getUserConfigDir("myapp", "1.2.3", "harawata", true));
System.out.println("User cache dir: "
+ appDirs.getUserCacheDir("myapp", "1.2.3", "harawata"));
System.out.println("User log dir: "
+ appDirs.getUserLogDir("myapp", "1.2.3", "harawata"));
System.out.println("User downloads dir: "
+ appDirs.getUserDownloadsDir("myapp", "1.2.3", "harawata"));
System.out.println("Site data dir: "
+ appDirs.getSiteDataDir("myapp", "1.2.3", "harawata"));
System.out.println("Site data dir (multi path): "
+ appDirs.getSiteDataDir("myapp", "1.2.3", "harawata", true));
System.out.println("Site config dir: "
+ appDirs.getSiteConfigDir("myapp", "1.2.3", "harawata"));
System.out.println("Site config dir (multi path): "
+ appDirs.getSiteConfigDir("myapp", "1.2.3", "harawata", true));
System.out.println("Shared dir: "
+ appDirs.getSharedDir("myapp", "1.2.3", "harawata"));
}
}
```
