/** @nosubgrouping
@brief NaCl application
Application running in [Google Chrome Native Client](https://developers.google.com/native-client/).
Supports keyboard and mouse handling.
This application library is available only in
@ref CORRADE_TARGET_NACL "Google Chrome Native Client", see respective sections
in @ref building-corrade-cross-nacl "Corrade's" and @ref building-cross-nacl "Magnum's"
building documentation. It is built if `WITH_NACLAPPLICATION` is enabled in
CMake.
## Bootstrap application
Fully contained base application using @ref Sdl2Application for desktop build
and @ref NaClApplication for Native Client build along with full HTML markup
and CMake setup is available in `base-nacl` branch of
[Magnum Bootstrap](https://github.com/mosra/magnum-bootstrap) repository,
download it as [tar.gz](https://github.com/mosra/magnum-bootstrap/archive/base-nacl.tar.gz)
or [zip](https://github.com/mosra/magnum-bootstrap/archive/base-nacl.zip) file.
After extracting the downloaded archive, you can do the desktop build in the
same way as with @ref Sdl2Application. For the Native Client build you also
need to put the contents of toolchains repository from https://github.com/mosra/toolchains
in `toolchains/` subdirectory. Don't forget to adapt `NACL_PREFIX` variable in
`toolchains/generic/NaCl-newlib-x86-32.cmake` and
`toolchains/generic/NaCl-newlib-x86-64.cmake` to path where your SDK is
installed. Default is `/usr/nacl`. You may need to adapt also
`NACL_TOOLCHAIN_PATH` so CMake is able to find the compiler.
Then create build directories for x86-32 and x86-64 and run `cmake` and
build/install commands in them. The toolchains need access to the platform
file, so be sure to properly set **absolute** path to `toolchains/modules/`
directory containing `Platform/NaCl.cmake`. Set `CMAKE_INSTALL_PREFIX` to
location of your webserver to have the files installed in proper location (e.g.
`/srv/http/nacl`).
mkdir build-nacl-x86-32 && cd build-nacl-x86-32
cmake .. \
-DCMAKE_MODULE_PATH="/absolute/path/to/toolchains/modules" \
-DCMAKE_TOOLCHAIN_FILE="../toolchains/generic/NaCl-newlib-x86-32.cmake" \
-DCMAKE_INSTALL_PREFIX=/srv/http/nacl
cmake --build .
cmake --build . --target install
mkdir build-nacl-x86-64 && cd build-nacl-x86-64
cmake .. \
-DCMAKE_MODULE_PATH="/absolute/path/to/toolchains/modules" \
-DCMAKE_TOOLCHAIN_FILE="../toolchains/generic/NaCl-newlib-x86-64.cmake" \
-DCMAKE_INSTALL_PREFIX=/srv/http/nacl
cmake --build .
cmake --build . --target install
See @ref cmake for more information.
You can then open `MyApplication` through your webserver in Chrome (e.g.
`http://localhost/nacl/MyApplication.html`).
## General usage
For CMake you need to copy `FindOpenGLES2.cmake` from `modules/` directory in
Magnum source to `modules/` dir in your project (so it is able to find OpenGL
ES). Request `NaClApplication` component, add
`${MAGNUM_NACLAPPLICATION_INCLUDE_DIRS}` to include path and link to
`${MAGNUM_NACLAPPLICATION_LIBRARIES}`. If no other application is requested,
you can also use generic `${MAGNUM_APPLICATION_INCLUDE_DIRS}` and
`${MAGNUM_APPLICATION_LIBRARIES}` aliases to simplify porting. Again, see
@ref building and @ref cmake for more information.
In C++ code you need to implement at least @ref drawEvent() to be able to draw
on the screen. The subclass must be then registered to NaCl API using
@ref MAGNUM_NACLAPPLICATION_MAIN() macro. See @ref platform for more
information.
@code
class MyApplication: public Platform::NaClApplication {
// implement required methods...
};
MAGNUM_NACLAPPLICATION_MAIN(MyApplication)
@endcode
If no other application header is included, this class is also aliased to
`Platform::Application` and the macro is aliased to `MAGNUM_APPLICATION_MAIN()`
to simplify porting.
### HTML markup and NMF file
You need to provide HTML markup for your application. Template one is below or
in the bootstrap application, you can modify it to your liking. The markup
references two files, `NaClApplication.js` and `WebApplication.css`, both are
in `Platform/` directory in the source tree and are also installed into
`share/magnum/` inside your NaCl toolchain. Change `&lt;application&gt;` to
name of your executable.
@code
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Magnum NaCl Application</title>
<meta charset="utf-8" />
<link rel="stylesheet" href="WebApplication.css" />
</head>
<body>
<h1>Magnum NaCl Application</h1>
<div id="listener">
<embed id="module" type="application/x-nacl" src="<application>.nmf" />
<div id="status">Initialization...</div>
<div id="statusDescription" />
<script src="NaClApplication.js"></script>
</div>
</body>
</html>
@endcode
You can modify all the files to your liking, but the HTML file must contain at
least the `&lt;embed&gt;` enclosed in listener `&lt;div&gt;`. The JavaScript
file contains event listeners which print loading status on the page. The
status displayed in the remaining two `&lt;div&gt;`s, if they are available.
The CSS file contains rudimentary style to avoid eye bleeding.
The `&lt;embed&gt;` file references NMF file which you need to provide too. If
you target @ref CORRADE_TARGET_NACL_NEWLIB "newlib", the file is pretty simple,
for example (change `&lt;application&gt;` to name of your executable):
@code
{
"program": {
"x86-32": {"url": "<application>-x86-32.nexe"},
"x86-64": {"url": "<application>-x86-64.nexe"}
}
}
@endcode
If you target @ref CORRADE_TARGET_NACL_GLIBC "glibc", you need to specify also
all additional dependencies. See [Native Client](https://developers.google.com/native-client/)
documentation for more information.
## Redirecting output to Chrome's JavaScript console
The application by default redirects @ref Corrade::Utility::Debug "Debug",
@ref Corrade::Utility::Warning "Warning" and @ref Corrade::Utility::Error "Error"
output to JavaScript console. See also @ref Corrade::Utility::NaClConsoleStreamBuffer
for more information.
