# Native-platform: Java bindings for various native APIs
|
||||
|
||||
A collection of cross-platform Java APIs for various native APIs. Supports OS X, Linux, Solaris and Windows.
|
||||
|
||||
These APIs support Java 5 and later. Some of these APIs overlap with APIs available in later Java versions.
|
||||
|
||||
## Available bindings
|
||||
|
||||
### System information
|
||||
|
||||
* Get kernel name and version.
|
||||
* Get machine architecture.
|
||||
|
||||
### Processes
|
||||
|
||||
* Get the PID of the current process.
|
||||
* Get and set the process working directory.
|
||||
|
||||
### Terminal and console
|
||||
|
||||
These bindings work for both the UNIX terminal and the Windows console:
|
||||
|
||||
* Determine if stdout/stderr are attached to a terminal.
|
||||
* Query the terminal size.
|
||||
* Switch between bold and normal mode on the terminal.
|
||||
* Change foreground color on the terminal.
|
||||
* Move terminal cursor up, down, left, right, start of line.
|
||||
* Clear to end of line.
|
||||
|
||||
### File systems
|
||||
|
||||
* Get and set UNIX file mode.
|
||||
* Create and read symbolic links.
|
||||
* List the available file systems on the machine
|
||||
* Query file system mount point.
|
||||
* Query file system type.
|
||||
* Query file system device name.
|
||||
* Query whether a file system is local or remote.
|
||||
|
||||
## Supported platforms
|
||||
|
||||
Currently ported to OS X, Linux and Windows. Support for Solaris and FreeBSD is a work in progress. Tested on:
|
||||
|
||||
* OS X 10.7.4, 10.8 (x86_64), 10.6.7 (i386)
|
||||
* Ubunutu 12.04 (amd64), 8.04.4 (i386, amd64)
|
||||
* Solaris 11 (x86)
|
||||
* Windows 7 (x64), XP (x86)
|
||||
|
||||
## Using
|
||||
|
||||
Include `native-platform.jar` and `native-platform-${os}-${arch}.jar` in your classpath. From Gradle, you can do
|
||||
this:
|
||||
|
||||
repositories {
|
||||
maven { url "http://repo.gradle.org/gradle/libs-releases-local" }
|
||||
}
|
||||
|
||||
dependencies {
|
||||
compile "net.rubygrapefruit:native-platform:0.3"
|
||||
}
|
||||
|
||||
You can also download [here](http://repo.gradle.org/gradle/libs-releases-local/net/rubygrapefruit/)
|
||||
|
||||
Some sample code to use the terminal:
|
||||
|
||||
import net.rubygrapefruit.platform.Native;
|
||||
import net.rubygrapefruit.platform.Terminals;
|
||||
import net.rubygrapefruit.platform.Terminal;
|
||||
import static net.rubygrapefruit.platform.Terminals.Output.*;
|
||||
|
||||
Terminals terminals = Native.get(Terminals.class);
|
||||
|
||||
// check if terminal
|
||||
terminals.isTerminal(Stdout);
|
||||
|
||||
// use terminal
|
||||
Terminal stdout = terminals.getTerminal(Stdout);
|
||||
stdout.bold();
|
||||
System.out.println("bold text");
|
||||
|
||||
## Changes
|
||||
|
||||
### 0.3
|
||||
|
||||
* Fixes to work with 64-bit OpenJDK 7 on Mac OS X. Thanks to Rene Gr<47>schke.
|
||||
|
||||
### 0.2
|
||||
|
||||
* Fixes to make native library extraction multi-process safe.
|
||||
* Fixes to windows terminal detection and reset.
|
||||
|
||||
### 0.1
|
||||
|
||||
* Initial release.
|
||||
|
||||
# Development
|
||||
|
||||
## Building
|
||||
|
||||
You will need to use the Gradle wrapper. Just run `gradlew` in the root directory.
|
||||
|
||||
### Ubuntu
|
||||
|
||||
The g++ compiler is required to build the native library. You will need the `g++` package for this. Usually this is already installed.
|
||||
|
||||
You need to install the `libncurses5-dev` package to pick up the ncurses header files. Also worth installing the `ncurses-doc` package too.
|
||||
|
||||
#### 64-bit machines with multi-arch support
|
||||
|
||||
Where multi-arch support is available (e.g. recent Ubuntu releases), you can build the i386 and amd64 versions of the library on the
|
||||
same machine.
|
||||
|
||||
You need to install the `gcc-multilib` and `g++-multilib` packages to pick up i386 support.
|
||||
|
||||
You need to install the `lib32ncurses5-dev` package to pick up the ncurses i386 version.
|
||||
|
||||
To build, include `-Pmultiarch` on the command-line.
|
||||
|
||||
### Windows
|
||||
|
||||
You need to install Visual studio, and build from a Visual studio command prompt.
|
||||
|
||||
### OS X
|
||||
|
||||
The g++ compiler is required to build the native library. You will need to install the XCode tools for this.
|
||||
|
||||
### Solaris
|
||||
|
||||
For Solaris 11, you need to install the `development/gcc-45` and `system/header` packages.
|
||||
|
||||
## Running
|
||||
|
||||
Run `gradle installApp` to install the test application into `test-app/build/install/native-platform-test`. Or
|
||||
`gradle distZip` to create an application distribtion in `test-app/build/distributions/native-platform-test-$version.zip`.
|
||||
|
||||
You can run `$INSTALL_DIR/bin/native-platform-test` to run the test application.
|
||||
|
||||

|
||||
|
||||
## TODO
|
||||
|
||||

|
||||
* Freebsd: fail for unsupported architecture.
|
||||
* Freebsd: build 32 bit and 64 bit libraries.
|
||||
|
||||
### Improvements
|
||||
|
||||
* Use wchar_to_java() for windows system and file system info.
|
||||
* Test network file systems on Mac, Linux, Windows
|
||||
* Test mount points on Windows
|
||||
* Cache class, method and field lookups (in particular for String conversions).
|
||||
* Determine C charset once at startup
|
||||
* Change readLink() implementation so that it does not need to NULL terminate the encoded content
|
||||
* Don't use NewStringUTF() anywhere
|
||||
* Don't use NewString() anywhere
|
||||
* Use iconv() to convert from C char string to UTF-16 when converting from C char string to Java String.
|
||||
* Support for cygwin terminal
|
||||
* Use TERM=xtermc instead of TERM=xterm on Solaris.
|
||||
* Add diagnostics for terminal.
|
||||
* Split out separate native library for terminal handling.
|
||||
* Version each native interface separately.
|
||||
* String names for errno values.
|
||||
* Split into multiple projects.
|
||||
* Convert to c.
|
||||
* Use fully decomposed form for unicode file names on hfs+ filesystems.
|
||||
* Extend FileSystem to deal with removable media.
|
||||
* Add a method to Terminal that returns a PrintStream that can be used to write to the terminal, regardless of what
|
||||
System.out/System.err point to.
|
||||
* Add a Terminal implementation that uses ANSI control codes. Use this on UNIX platforms when TERM != 'dumb' and
|
||||
libncurses cannot be loaded.
|
||||
* Add a method to Terminal that indicates whether the cursor wraps to the next line when a character is written to the
|
||||
rightmost character position.
|
||||
|
||||
### Ideas
|
||||
|
||||
* Expose platform-specific HTTP proxy configuration. Query registry on windows to determine IE settings.
|
||||
* Expose native named semaphores, mutexes and condition variables (CreateMutex, CreateSemaphore, CreateEvent, semget, sem_open, etc).
|
||||
* Expose infromation about network interfaces.
|
||||
* Fire events when filesystems or network interfaces change in some way.
|
||||
* Fire events when terminal size changes.
|
||||
* Fire events when files change.
|
||||
* Expose system keystores and authentication services.
|
||||
* Expose a mechanism for generating a temporary directory.
