Note: This SDK will evolve over time to include additional content. As such, the organization of the files within the SDK may change. Please monitor the release notes for notifications of the movement of any of the components.
This guide describes the requirements and procedure for installing the LunarG Vulkan SDK for macOS. This SDK provides the development and runtime components required to build, run, and debug MoltenVK-subset Vulkan applications. Refer to the LunarG Vulkan SDK, Documentation, and Known Issues at the LunarXchange website for the most current SDK information.
The Vulkan API is a low overhead, explicit, cross-platform graphics API that provides applications with direct control over the GPU, maximizing application performance. For more information on the Vulkan specification and API, refer to Khronos.org. For tutorial-level information, refer to LunarG's Vulkan tutorial, which can be found on the LunarXchange website.
This SDK provides partial Vulkan support though the use of the MoltenVK library which is a "translation" or "porting" library that maps most of the Vulkan functionality to the underlying graphics support on macOS and iOS platforms. The MoltenVK library takes on the role of the Installable Client Driver (ICD) from the point of view of the application and the Vulkan loader. It is NOT a fully-conforming Vulkan driver for macOS or iOS devices. Please see the MoltenVK Runtime User Guide on the MoltenVK GitHub for more information.
This SDK includes MoltenVK libraries for iOS that allow targeting MoltenVK applications for iOS from a macOS/Xcode development environment. This support is in the form of a MoltenVK framework and a MoltenVK library for iOS which can be used for building applications intended for deployment on iOS devices.
This SDK does not yet include Vulkan loader or validation layer libraries that are ready for deployment on iOS systems. Until these components become available for deployment on iOS, MoltenVK iOS applications should link to the MoltenVK libraries directly without using the Vulkan loader. Validation and other layer support is consequently not available on iOS without the Vulkan loader. Instructions for using the MoltenVK libraries directly are available in the MoltenVK Runtime User Guide.
If you have a problem with the SDK, please determine if it is a specific functional problem with one of the components in the SDK. Use the "SDK Origins" section in this document to find a list of repositories that make up this SDK. If you can determine that the problem is in a component that comes from one of these repositories, please report the problem there. For example, a problem with the Vulkan loader is best reported in the KhronosGroup/Vulkan-Loader
GitHub repository.
Otherwise, if you have a question with the SDK itself, such as how to use the SDK components on macOS, please use the issue reporting system on LunarXchange.
| Term | Description |
|---|---|
| ICD | Installable Client Driver: A Vulkan-compatible display driver. In this SDK, the ICD is the MoltenVK library. |
| GLSL | OpenGL Shading Language |
| Layer | A library designed to work as a plug-in for the loader. It usually serves to provide validation and debugging functionality to applications. |
| Loader | A library which implements the Vulkan API entry points and manages layers, extensions, and drivers. It can be found in the SDK, as well as independent hardware vendor driver installs |
| MoltenVK | A library that maps most of the Vulkan functionality to underlying graphics support on macOS and iOS. |
| SPIR-V | Standard Portable Intermediate Representation: A cross-API intermediate language that natively represents parallel compute and graphics programs. |
| Vulkan | A low overhead, explicit graphics API developed by the Khronos Group and member companies. |
| WSI | Window System Integration |
| Xcode | The preferred application development environment for macOS and iOS applications. |
The components in this SDK are built with a specific version of Khronos Vulkan API header, whose version is reflected in the SDK's version number. For example, SDK version 1.0.xx.0 indicates that the SDK uses Vulkan header revision 1.0.xx where:
The last number in the SDK version indicates the revision of an SDK for the given Vulkan header revision. It is used in case it is necessary to release multiple SDKs for the same version of Vulkan.
Download the LunarG Vulkan SDK from the LunarXchange website. The SDK download file is named with the pattern:
vulkansdk-macos-1.1.xx.0.tar.gz
Make note of the directory to which the file was downloaded.
The Safari web browser is often configured to "open" files after downloading. This may cause Safari to uncompress the tar.gz
file after downloading, resulting in a tar
file. In this case, you need to locate the tar
file and not the tar.gz
file and proceed with the rest of the steps in the same manner with the tar
file.
Installing is a simple operation involving expanding a "tar" archive file into your work area. The macOS SDK is intended to be installed anywhere the user can place files such as the user's $HOME
directory. The SDK isn't configured to install to protected system locations such as /usr/lib
or /System
.
If using Finder
, navigate to the downloaded file and drag it to where you want to install it. Once the tar.gz
or tar
file is in the desired location, double-click on it in Finder
to expand the archive. The archive expansion creates a directory containing the SDK contents that has the same name as the file.
If using the command line in Terminal
, use shell commands to move the tar.gz
file to where you want to install it and run tar -xzf filename
to expand. If the file is a tar
file, then tar -xf filename
will suffice.
Note that since each SDK version has a unique name, you are able to install and use multiple versions of the SDK on your system.
This section describes how the SDK contents are organized.
The Applications
directory contains several Vulkan demos that are packaged as macOS application "bundles". These applications are totally self-contained and can be launched immediately from this directory. They can also be "installed" by "drag-and-drop" operations in Finder
to any desired location.
These bundles contain all libraries and resources needed to run the applications and require no additional installation steps.
The vulkaninfo
application opens a new Terminal
window to display its output since it is not a graphical windowed application.
Note: macOS has a security feature that prevents the opening of unsigned applications. If you get a message saying that the application cannot be opened because it is from an unidentified developer, you can control-click the application icon and then select "Open" from the shortcut menu. Then click "Open" to proceed. See this article for more information. The exact details may vary across different releases of macOS.
The macOS/Frameworks
directory contains a Vulkan framework which contains the headers and libraries for easy inclusion in an Xcode project.
The MoltenVK
directory contains MoltenVK frameworks and libraries built from the MoltenVK repository for both macOS and iOS. You can add these to your Xcode projects to link in the MoltenVK support. But you would tend to need these only if not using the Vulkan loader to load the MoltenVK driver.
The macOS
directory is the root of a "system tree" containing Vulkan executables, include files, and libraries in the traditional bin
, include
, lib
structure. This tree contains the Vulkan components such as the loader library and layer libraries.
This tree also contains executables, include files, and libraries for various Vulkan-related tools such as glslang, SPIRV-Tools, and others.
It is often useful to point system environment variables (e.g., PATH
, DYLD_LIBRARY_PATH
) and Vulkan-related environment variables (e.g., VK_LAYER_PATH
) to directories in this directory to locate the components found in this tree.
The Documentation
directory contains SDK and Vulkan Documentation such as:.
Much of the content found in the SDK is collected from several public GitHub repositories and is built and packaged to form the delivered SDK. You may wish to refer to these repositories for more information about a particular component or if you need to obtain and build one of the components yourself.
The primary repositories are:
Several other repositories are "pulled in" by the above repositories. Some of these are:
If you have a problem with a component and can determine its origin from the list above, please open a problem report in the appropriate GitHub repository.
The Vulkan SDK is flexible in the sense that it can support various workflows. Some of these workflows are summarized here and are explained in greater detail later in this document.
Your Xcode project copies all required components from the SDK and places them in the application bundle. This results in a standalone application that can be copied or published anywhere and does not require the user to have an SDK installed.
Using Xcode, add the various components from the SDK to your Xcode project.
Note that while this results in a totally self-contained application bundle, these components are placed into the bundle rather statically and cannot be easily upgraded.
This presents a trade-off between potential improved stability of the application versus the flexibility of being able to upgrade the Vulkan components.
Your Xcode project has references to the SDK and requires that an SDK be installed on your system. This workflow might be a development phase that eventually leads to the bundled application workflow. This typically requires you to set Xcode Environment variables and or Xcode custom paths to point to your SDK location.
macOS discourages third-parties from installing libraries or frameworks to system directories. But it is possible for application developers to put together their own macOS "Packages" that come with an application and are installed when the application is installed. This may be a good approach for putting the Vulkan components into a place where they can be updated without updating the application.
macOS also allows users to install files to /usr/local
which may be convenient for users who prefer this approach. There are no "install" scripts provided with this SDK, but you can manually install desired SDK files to the appropriate system locations.
The applications in the Applications directory are simple pre-built demos that you can launch immediately from Finder
.
You can also start them from the command line with open
.
You may need to set environment variables inside the Xcode interface when working with Xcode projects that use SDK components. You may also need to set environment variables in your command shell when running some non-bundled vulkan applications or other SDK tools from the command line.
For these purposes, the following variables are useful. (Replace vulkansdk
with the path to your SDK installation.)
PATH
- Add vulkansdk/macOS/bin
to this path to make it easy to run vulkaninfo
and the various glslang and SPIRV-Tools installed there.
DYLD_LIBRARY_PATH
- Add vulkansdk/macOS/lib
to this path so that executables can load the libraries installed there. This should rarely be needed and is not necessary for libraries that are located by JSON files, such as the ICD and layer libraries.
VK_LAYER_PATH
- set to point at the layer JSON files in vulkansdk/macOS/etc/vulkan/explicit_layer.d
so that the vulkan loader can locate the layers installed in the SDK via these JSON files.
VK_ICD_FILENAMES
- set to point at the JSON file for the MoltenVK ICD, which is located at vulkansdk/macOS/etc/vulkan/icd.d/MoltenVK_icd.json
. This ICD library itself is installed in the SDK in the SDK's macOS/lib
directory and is pointed to by this JSON file.
The rest of this guide explains when to use these variables.
The SDK contains a command line version of vulkaninfo
in the macOS/bin
directory. This is a non-bundled Vulkan command line application and so needs some environment variables set in order to function properly.
Here's how to set this up, using the Terminal
application:
Set a convenience variable to point to the SDK:
export VULKAN_SDK=vulkansdk/macOS
Replace the "vulkansdk" above with the actual path to your SDK. Make sure you include the /macOS
part.
Add the bin dir to your PATH
so that you can run programs from there:
export PATH=$VULKAN_SDK/bin:$PATH
Add the lib dir to your DYLD_LIBRARY_PATH
so that programs find the Vulkan loader library:
export DYLD_LIBRARY_PATH=$VULKAN_SDK/lib:$DYLD_LIBRARY_PATH
Now you can run vulkaninfo
from any directory and you should see an error saying that it cannot create a Vulkan instance. This is because we have not told the Vulkan loader where to find a driver. Fix this with:
export VK_ICD_FILENAMES=$VULKAN_SDK/etc/vulkan/icd.d/MoltenVK_icd.json
Run vulkaninfo
again and you should see something like:
bash-3.2$ vulkaninfo
==========
VULKANINFO
==========
Vulkan API Version: 1.0.68
Instance Extensions:
====================
Instance Extensions count = 3
VK_KHR_surface : extension revision 25
VK_MVK_macos_surface : extension revision 2
VK_EXT_debug_report : extension revision 9
Layers: count = 6
=======
VK_LAYER_LUNARG_core_validation (LunarG Validation Layer) Vulkan version 1.0.65, layer version 1
Layer Extensions count = 1
VK_EXT_debug_report : extension revision 6
Devices count = 2
GPU id : 0 (AMD Radeon Pro 560)
Layer-Device Extensions count = 1
VK_EXT_debug_marker : extension revision 4
GPU id : 1 (Intel(R) HD Graphics 630)
Layer-Device Extensions count = 1
VK_EXT_debug_marker : extension revision 4
(Output truncated for brevity)
You can also run with the validation layers enabled:
export VK_LAYER_PATH=$VULKAN_SDK/etc/vulkan/explicit_layer.d
VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_standard_validation vulkaninfo
Since there shouldn't be any validation errors in vulkaninfo
, you can expect the same output.
Note that there's a bundled version of vulkaninfo
in the SDK's Applications directory which may be easier to use since the above configuring is not required. But if you use non-bundled Vulkan applications from the command line frequently, you may wish to set these environment variables in your login scripts or install the components to system locations.
macOS is comparable to other UNIX-like operating systems in that you can install components to system directories as a "super-user". macOS is also a bit more locked down in the sense that a super-user can't easily install to places like /usr/bin
. However, it is fairly easy to install to places like /usr/local/bin
.
This SDK currently does not directly support or encourage installing SDK components to system directories.
But if you are interested in installing SDK components to system directories, you can do so manually and pick only the components you need to install. This may be helpful for reducing the need to set environment variables to locate the components that reside in your SDK directory.
For example, to install the ICD to the system directories:
vulkansdk/macOS/lib/libMoltenvVK.dylib
to /usr/local/lib
/etc/vulkan/icd.d
vulkansdk/macOS/etc/icd.d/MoltenVK_icd.json
to /etc/vulkan/icd.d
/etc/vulkan/icd.d/MoltenVK_icd.json
library_path
to remove any leading path, leaving just libMoltenVK.dylib
The Application bundle for the vkcube.app
looks like:
vkcube.app
Contents
Frameworks
libMoltenVK.dylib
Info.plist
MacOS
vkcube
libvulkan.1.0.69.dylib
libvulkan.1.dylib -> libvulkan.1.0.69.dylib
Resources
LunarGIcon.icns
Main.storyboardc
Info.plist
MainMenu.nib
NSWindowController-B8D-0N-5wS.nib
XfG-lQ-9wD-view-m2S-Jp-Qdl.nib
vulkan
icd.d
MoltenVK_icd.json
Note that all required components are in the bundle.
The SDK also provides the Vulkan loader as a Framework in addition to a standalone library. This allows you to add the Vulkan loader support to your application as a Framework if you wish. This process is demonstrated later in this document.
The Vulkan loader for macOS searches the same paths for ICDs and Layers as the Vulkan Loader for Linux. These paths are described in The Loader And Layer Interface document.
The macOS loader also looks in the application's bundle for ICD and layer JSON files. It looks in the bundle's Resources/vulkan/icd.d
directory for ICD JSON files and in the bundle's Resources/vulkan/explicit_layer.d
directory for layer JSON files. The ICD JSON file (MoltenVK_icd.json
) can be seen in the bundle shown above.
If the executable is in a bundle, the loader searches the bundle first before searching the system directories.
If you wish to bundle the MoltenVK ICD into your application, you need to put a modified version of the MoltenVK_icd.json
file in your bundle's Resources/vulkan/icd.d
folder to allow the loader to find the MoltenVK library in your bundle. Assuming that you intend to ship the MoltenVK library in the Frameworks
directory, as in the vkcube example above, you would make a copy of the file vulkansdk/macOS/etc/icd.d/MoltenVK_icd.json
from the SDK.
Edit this copy to modify the library_path
:
Original:
{
"file_format_version" : "1.0.0",
"ICD": {
"library_path": "./libMoltenVK.dylib",
"api_version" : "1.0.0"
}
}
Modified:
{
"file_format_version" : "1.0.0",
"ICD": {
"library_path": "../../../Frameworks/libMoltenVK.dylib",
"api_version" : "1.0.0"
}
}
Then use this modifed file when creating your application bundle.
Since the Vulkan header files and loader are provided in a framework (macOS/Frameworks/vulkan.framework
), it is fairly easy to add these to your Xcode project, just like any other framework. However, if you wish your project to have run-time access to the MoltenVK ICD and Vulkan validation layers, you will have to guide the Xcode project to those components residing in the SDK.
This section covers these details.
If you want your Xcode project to refer to components residing in an SDK instead of bundling these components, you can set environment variables in your Xcode project to point to these components instead of bundling them.
This may be a technique suitable for developers whose workflows are compatible with "pointing" to a specific SDK during their work. It is unlikely that anyone would want to deploy an application that requires an SDK to be present.
Here are some approaches for setting these variables:
Xcode has an interface for setting environment variables in the "Scheme" panel. This is a fairly common and straightforward approach.
Environment variables set in your shell will not be seen by Xcode if Xcode is launched from Launchpad or other desktop GUI. You may be able to pass shell environment settings into Xcode by starting Xcode with open
from a bash shell command line where the environment variables are set. With Xcode versions 7 and later, you may need to enable this behavior:
defaults write com.apple.dt.Xcode UseSanitizedBuildSystemEnvironment -bool NO
Configure the system-wide Preferences for Xcode by adding Custom Paths in the Preference's Locations tab.
You can add Vulkan loader support to your application by adding the Vulkan framework to your project, or by adding the Vulkan header files and Vulkan loader library file individually to your project. The framework approach is described in the following Xcode examples.
The other approach is similar. You add the SDK's macOS/include
directory to the project's Header Search Paths. And you add both the libvulkan.1.dylib
and the libvulkan.1.0.xx.dylib
to your application's folder in the Project Navigator. Like in the Framework examples below, you may have to add a Copy Files step to copy these two files into the compiled project.
libvulkan.1.dylib
is a symbolic link to libvulkan.1.0.xx.dylib
. You may prefer to link only to libvulkan.1.0.xx.dylib
or rename libvulkan.1.0.xx.dylib
to libvulkan.1.dylib
and use libvulkan.1.dylib
in your project.
Here are some simple step-by-step instructions for creating Xcode projects from scratch that create Vulkan instances and load validation layers.
main.cpp
using the Project Navigator#include <iostream>
#include <vulkan/vulkan.h>
int main(int argc, const char * argv[]) {
VkInstance instance;
VkResult result;
VkInstanceCreateInfo info = {};
result = vkCreateInstance(&info, NULL, &instance);
std::cout << "vkCreateInstance result: " << result << "\n";
vkDestroyInstance(instance, nullptr);
return 0;
}
Note that Xcode will show you some errors, including not finding vulkan.h and unknown Vulkan types and symbols.
macOS/Frameworks/vulkan.framework
to your application's top directoryReturn to your source code and you should see that the errors have cleared out.
If not, follow whatever procedures are necessary for adding a private framework in your version of Xcode. These procedures may vary across versions of Xcode. For example, if Xcode still cannot find vulkan.h
, add the path to the SDK include directory to your projects header search path.
Go ahead and compile the code and run it. You should see the vkCreateInstance
call return a -9. Find the vulkan_core.h file under the Frameworks area in the Project Navigator and see that a -9 means INCOMPATIBLE DRIVER
. This is happening because the Vulkan loader doesn't know where to find the MoltenVK ICD.
VK_ICD_FILENAMES
vulkansdk/macOS/etc/vulkan/icd.d/MoltenVK_icd.json
Rerun the application. The vkCreateInstance
call should return 0.
Next, we'll add code to get a list of layers installed on the system.
Update your code to look like:
#include <iostream>
#include <vulkan/vulkan.h>
int main(int argc, const char * argv[]) {
VkInstance instance;
VkResult result;
VkInstanceCreateInfo info = {};
uint32_t instance_layer_count;
result = vkEnumerateInstanceLayerProperties(&instance_layer_count, nullptr);
std::cout << instance_layer_count << " layers found!\n";
if (instance_layer_count > 0) {
std::unique_ptr<VkLayerProperties[]> instance_layers(new VkLayerProperties[instance_layer_count]);
result = vkEnumerateInstanceLayerProperties(&instance_layer_count, instance_layers.get());
for (int i = 0; i < instance_layer_count; ++i) {
std::cout << instance_layers[i].layerName << "\n";
}
}
result = vkCreateInstance(&info, NULL, &instance);
std::cout << "vkCreateInstance result: " << result << "\n";
vkDestroyInstance(instance, nullptr);
return 0;
}
Compile and run this code and notice that no layers are found. We need to tell the Vulkan loader where to find the layers.
VK_LAYER_PATH
vulkansdk/macOS/etc/vulkan/explicit_layer.d
Run the progam again and it should list the layers on the system.
Finally, we'll actually load the validation layers and make sure that they are working.
Update your code:
#include <iostream>
#include <vulkan/vulkan.h>
int main(int argc, const char * argv[]) {
VkInstance instance;
VkResult result;
VkInstanceCreateInfo info = {};
uint32_t instance_layer_count;
result = vkEnumerateInstanceLayerProperties(&instance_layer_count, nullptr);
std::cout << instance_layer_count << " layers found!\n";
if (instance_layer_count > 0) {
std::unique_ptr<VkLayerProperties[]> instance_layers(new VkLayerProperties[instance_layer_count]);
result = vkEnumerateInstanceLayerProperties(&instance_layer_count, instance_layers.get());
for (int i = 0; i < instance_layer_count; ++i) {
std::cout << instance_layers[i].layerName << "\n";
}
}
const char * names[] = {
"VK_LAYER_LUNARG_standard_validation"
};
info.enabledLayerCount = 1;
info.ppEnabledLayerNames = names;
result = vkCreateInstance(&info, NULL, &instance);
std::cout << "vkCreateInstance result: " << result << "\n";
vkDestroyInstance(instance, nullptr);
return 0;
}
Compile and run and you should see a validation error message complaining that the sType
field is not set to the expected value.
This is not surprising because the VkInstanceCreateInfo
structure was simply initialized to 0, except for the validation layer name list. You can experiment further by fixing this problem and see what happens next.
You can also build applications using this SDK with CMake.
CMake versions 3.7 and later include a FindVulkan.cmake
module that is useful for locating the SDK and using it in CMake projects. This module relies on the VULKAN_SDK
environment variable to locate the SDK. If this variable is not set, the module looks in the standard system locations such as /usr/local
.
Assuming that you have set the VULKAN_SDK
environment variable to the macOS
directory in your SDK installation:
export VULKAN_SDK=path-to-sdk/macOS
then the CMake find_package(vulkan)
command can find the needed components in the SDK.
This example uses CMake to create both "Unix Makefiles" and Xcode projects to build the console version of the vulkaninfo
application.
Create an empty directory and copy the source code for vulkaninfo
from the Khronos Group Vulkan-Tools GitHub repository. The file is vulkaninfo/vulkaninfo.c
.
Create the file CMakeLists.txt
and populate it with the following contents:
cmake_minimum_required(VERSION 3.7)
project(vulkaninfo)
find_package(vulkan REQUIRED)
add_executable(vulkaninfo vulkaninfo.c)
target_link_libraries(vulkaninfo Vulkan::Vulkan)
Assuming that the current directory is this new directory now containing vulkaninfo.c
and CMakeLists.txt
, build the project:
mkdir build
cd build
cmake ..
make
You can then run the application:
export VK_ICD_FILENAMES=$VULKAN_SDK/etc/vulkan/icd.d/MoltenVK_icd.json
./vulkaninfo
You can then debug the project with lldb
or other debugger. You may want to rebuild using:
cmake -DCMAKE_BUILD_TYPE=Debug ..
to build with debugging information.
If you prefer, you can build an Xcode project:
mkdir build
cd build
cmake -GXcode ..
open vulkaninfo.xcodeproj
and then work with the code in this Xcode project.


In this paragraph only the phrase Hello World will be translated upon change of language. This is done by assigning it an id shared between all of it's translations.
In this paragraph the words dog and cat will be translated upon change of language. Again like the previous example, this is done by shared ids across all translations, with the exception that the word itself is used as the id.
This entire paragraph will be translated uponchange of language. This is done by fetching the translated data from an external source (in this case a GET request to the server) when it is needed.


Motorcyclist airlifted to hospital following collision in Sooke

B.C. Emergency Health Services received a call at 2:36 p.m. about an accident on West Coast Road near the intersection of Atherley Close, just down the road from an ambulance station. Paramedics were on the scene with two ambulances and an air ambulance in about a minute.
Emergency services did not have information on the patient’s condition at this time.

Allowed values: MySQL, SqlServer, Oracle, Sqlite, Postgresql, Derby, Other. (You must type the names exactly, matching case.)
If Other, you must specify a value for the driverclass argument (JDBC connection string and class).
Note: some types not yet implemented.


Example 6. hello, world
To use the shellout(3m) module effectively there are a few important rules that must be followed. One, is that the sho_close function calls wait(2) and will not return until the process spawned within the shell exits. If the child program is well behaved this can be achived by sending "exit $?\n" however doing so will not trigger the shell to exit if it is not ready to receive input.
Tip: If your program is not responding it is possible to write the special Ctrl-C chacter. For example on Linux at least this appears to be "\x03". If the process still does not respond a kill(2) can be used to send a SIGKILL to sh->pid however even though this is almost garunteed to get shell control back take care that it does not leave a zombie process lingering in the background.
The below code is a minimal "hello, world" example that opens a new /bin/sh shell with sho_open and writes the command "echo hello, world\n" to it. Note the '\n' character is as important as it is equivalent to pressing the 'Enter' key. Then it calls sho_expect which will wait for the command prompt 'sh> ' to come back. The command prompt is defined by the ps1 parameter to sho_open so the caller will know what it is and that it is uniqe to the expected output.
struct sho *sh; const char *cmd = "echo hello, world\n"; const char *pv[] = { "sh> " }; char buf[256]; int i; sh = sho_open("sh", pv[0], 0); writen(sh->ptym, cmd, strlen(cmd)); i = sho_expect(sh, pv, 1, buf, 256, 10); if (i == 1) { fprintf(stderr, "success: %s\n", buf); } else if (i == -1) { perror("timeout"); } else if (i == 0) { fputs("EOF\n", stderr); } /* output */ success: hello, world sh>In this example the caller knows when the command has completed when the command prompt is returned. Keep in mind that it is usually a better stategy to wait for the command prompt and then interpret the output in the buffer so that unexpected output doesn't result in a timeout. Provided the logic is equipted to handle the unexcepted output it might be perfectly reasonable to call sho_expect with other strings in the pattern vector. For example, to get a list of mounted filesystems the mount(8) command might be used with no arguments. If the pattern vector were change to: const char *pv[] = { "sh> ", "\n" }; for example the sho_expect function would return with each line in the buffer which assists in parsing the values in each mount entry.
The svcond(3m) module is not available in the Win32 environment. This module also does not work on HP-UX because it does not support the forkpty(3) function.
The struct sho structure
Synopsis
Description
#include <mba/shellout.h> SHO_FLAGS_INTERACT SHO_FLAGS_ISATTY struct sho { char ps1[32]; int flags; pid_t pid; int ptym; struct termios t0; };
The sho_open function
Description
#include <mba/shellout.h> struct sho *sho_open(const char *sh, const char *ps1, int flags);
The sho_close function
Description
#include <mba/shellout.h> int sho_close(struct sho *sh);
The sho_expect function
Description
#include <mba/shellout.h> int sho_expect(struct sho *sh, const char *pv[], int pn, char *dst, size_t dn, int timeout);
The sho_loop function
Description
#include <mba/shellout.h> int sho_loop(struct sho *sh, const char *pv[], int pn, int timeout);
When combined with the SHO_FLAGS_INTERACT flag passed to sho_open this will effectively create a shell within a shell. Note, currently some programs will not operate correctly (e.g. vi) because certain termios flags are not optimal for interactive sessions. This would need futher study.

all about us!
We started Detour Media because we love to make cool stuff! With the world online, video is now more important than ever when it comes to attracting new customers. We specialize in creating custom material designed for social media and web so you can show the world the great things that you do.


The number and impact of natural, technological and human-made disasters and emergencies are rising in Canada and globally. As a result, demands for HQPs in disaster and emergency management profession and relevant industries have sharply increased in recent years and will continue to grow in the future.
The long term goal of ADERSIM is to enhance Canada's scientific and technological capacities in public safety and emergency management through innovative training, research, and development of professionals in state-of-the-art simulation and emergency management systems.
Developing successful disaster and emergency simulation tools requires backgrounds in four key areas: subject disaster risk (flood, earthquake, hurricane, industrial accidents, etc.), disaster and emergency management functions (search and rescue, disaster logistics, evacuation, etc.), disaster and emergency information management (spatial and non-spatial), and mathematical modeling and computer simulation.
The ADERSIM program facilitates the transition of trainees into the workforce that includes academia, industry, government, and non-governmental organizations. PDF and PhD trainees will be able to find jobs in a growing academic environment related to public safety and emergency management.

Duration
20 minutes
Lab goals
In this exercise, you'll start with an existing Xamarin.iOS project which has serveral isolated View Controllers defined in a storyboard. Using the Xamarin.iOS designer, you will add a UINavigationController
to implement stack navigation.
Required Assets
There is a Exercise 1 folder included with this lab exercise which contains a starter project you will use to begin, assets you'll need to add to your project, and a completed project you can use to check your work.
Steps
This is a individual exercise, intended to be done on your own, use the step-by-step instructions to complete the exercise.
Open the starter project
As a first step, let's open the starter project. Optionally, run the project, you should see a simple clock.
- Open the Clock solution in the Exercise 1/Start folder.
- Open the MainStoryboard.storyboard file and examine the View Controllers that have been added.
Add a Navigation Controller
Next we'll add a UINavigationController
using the iOS Designer.
- Add a Navigation Controller from the ToolBox to the storyboard. Notice that it will add two View Controllers: a Navigation Controller and a "Root View Controller".
- Delete the "Root View Controller" by clicking on the grey bar at the bottom of the View Controller and pressing the delete key.
- Add a
UITableViewController
to the design surface. - Set the Table View Controller as the root of the Navigation Controller by control dragging from the Navigation controller to the table view controller.
- Select the the table view controller's navigation bar and examine the properties pane. In the Navigation Item section, set the Title filed to Main Menu. Alternativitely, you can double-click on the title to edit.
- And finally, move the Sourceless Segue in the storyboard from the Clock View Controller to the new Navigation Controller.
Setup the prototype cell
-
Name the
UITableView
by selecting the UITableView (not the controller) and give it a Name of "MyTableView". - Select the prototype cell on the Table View Controller and set the style to "Basic", set the Identifier to "cellid" and set the Accessory to "Disclosure Indicator".
Add data to the Table
We're now going to add a backing class and connect a UITableViewSource
.
To save time this has been provided in the Assets folder under Exercise 1.
-
Add both the MenuTableViewController.cs and the MenuTableViewController.designer.cs file to the project.
Set the Class name in the designer for the
UITableViewController
to MenuTableViewController.
Wire up the Navigation
Our final step is to launch the individual sections of our clock app when the rows in our table view are tapped.
-
In the
RowSelected
method in our new Table View Source (in MenuTableViewController.cs), use theInstantiateViewController
method to instantiate each section of our clock app. - Run the app, you should be able to navigate to and from all three screens.
(Bonus) Passing Data when using Segues
If you have time, add an additional level to our stack navigation by adding a screen to display split times for our stop watch. We'll need to pass the list of split times from the Stop Watch screen to the Splits screen.
- Open the designer and control-drag from the View Splits button on the Stop Watch screen to to the SplitsViewController. Set the Action to Push.
-
In the StopwatchViewController, add a new method override for
PrepareForSegue
. -
This method will let us interact with the Destination View Controller before it's shown.
Add code to read the destination screen from the segue, cast it to a
SplitsViewController
, and pass the list of split times to theSplitTimes
property. - Use the completed project if you need a hint or compare it to your solution when you're finished.
Summary
Congratulations! You have successfully implemented stack navigation using the Navigation Controller.

A number of message strip types are available. They offer preset styling for different contextual situations. Can be one of 'warning', 'success', 'information', 'error' or normal (default).
If you want to have a custom icon, that is also supported using the *fdMessageStripIcon
directive.
[noIcon]
property to true
.
[width]
and
[minWidth]
properties.
If the application needs a custom Message Strip, other than the semantic variations, then the colours from
Inverted Object Status/Tag control should be used. Use the input [indicationColor]
with values
number from 1 to 10 for the first set, and 1b to 10b for the second set.
Message Strip Alerts are used to display a short, important message in a prominent location on the page. They are used to inform users of a situation that requires their attention or action. They are not part of the Fiori Design guidelines.
This example shows usage of the MessageStripAlertService
. You can set custom footer for rendering
actions. You can use TemplateRef<{{ '{' }}$implicit: MessageStripAlertRef{{ '}' }}>
, ordinary
string or the component.
If you choose to have component as a content, you can use MessageStripAlertRef
to close the alert,
or get some data from it.
Message stripe alert containers are responsive. Below the M
(1024px) breakpoint, the alerts from all
the positions are unified into either bottom-middle
or top-middle
positions, depending
on their vertical position requirement and they are ordered by the time of appearance.
If from the vertical positions(bottom or top) only one is used, then the container will take all the viewport height, and it will have a scrollbar if the content is bigger than the viewport. If both vertical positions are used, the container will take only half of the viewport height.
Message Strip can be automatically dismissed after a specified amount of time. To enable this feature, use
AutoDismissMessageStripDirective
directive.


The us_murder_rate
object defined above represents just one number. Yet we are storing it in a data frame:
class(us_murder_rate)
#> [1] "data.frame"
since, as most dplyr functions, summarize
always returns a data frame.
This might be problematic if we want to use this result with functions that require a numeric value. Here we show a useful trick for accessing values stored in data when using pipes: when a data object is piped that object and its columns can be accessed using the pull
function. To understand what we mean take a look at this line of code:
us_murder_rate %>% pull(rate)
#> [1] 3.03
This returns the value in the rate
column of us_murder_rate
making it equivalent to us_murder_rate$rate
.
To get a number from the original data table with one line of code we can type:
us_murder_rate <- murders %>%
summarize(rate = sum(total) / sum(population) * 100000) %>%
pull(rate)
us_murder_rate
#> [1] 3.03
which is now a numeric:
class(us_murder_rate)
#> [1] "numeric"
Run the sample code to see how pull() function works.
DO NOT CLICK RUN
library(dplyr)
library(dslabs)
data(heights)
data(murders)
murders <- murders %>% mutate(rate = total/population*100000)
us_murder_rate <- murders %>%
summarize(rate = sum(total) / sum(population) * 100000)
# print us_murder_rate
us_murder_rate
# pull rate column from the us_murder_rate
us_murder_rate %>% pull(rate)

The Constitution specifies that a majority of members constitutes a quorum to do business in each house. Representatives and senators rarely force the presence of a quorum by demanding quorum calls; thus, in most cases, debates continue even if a majority is not present.
The Senate uses roll-call votes; a clerk calls out the names of all the senators, each senator stating "aye" or "no" when his or her name is announced. The House reserves roll-call votes for the most formal matters, as a roll-call of all 435 representatives takes quite some time; normally, members vote by electronic device. In the case of a tie, the motion in question fails. In the Senate, the Vice President may (if present) cast the tiebreaking vote.

Brett currently lives in Guelph, ON with his wife, Andrea, and cat who is too cute and smart for her own good (but that doesn't make him a cat person; his wife thinks otherwise).
Alex is an open source engineer. He works on Topaz, PyPy, CPython, and Django as well as serves on the board of the Python Software Foundation. He works as an engineer at Rackspace, and lives in San Francisco.
Lynn Root is a software engineer for Red Hat on the freeIPA.org team, known for breaking VMs and being loud about it. She is the founder & leader of PyLadies San Francisco, board member of the Python Software Foundation, and a missionary for the PyLadies word. Lastly, she has an unhealthy obsession for coffee, twitter, and socializing.
Christopher is a programmer from Hobart, in the Australian state of Tasmania. He currently works as an Android developer at AsdeqLabs, which means his day job involves more Java than he'd like. His main interest in Python has become community development, he is an immediate past convenor of PyCon Australia 2012 and 2013, and is a newly-minted member of the Python Software Foundation.
Christopher sees PyCon Canada as a wonderful opportunity to return to attending Python conferences without the stress of organising one. In his newly-found spare time, he enjoys presenting on Mobile development at Open Source conferences, and presenting on Open Source development at Mobile conferences.
Jessica Kerr is known in her hometown of St. Louis as "that one girl, at the user groups, who gets excited." Online, she is known as Jessitron, as she blogs and tweets her excitement to the world. Jessitron writes code in Scala, Ruby, and whatever else looks interesting. She is fascinated by functional programming, git, Software Carpentry, her two children, and other paths into the future.
Brandon is thrilled to be returning for the second PyCon Canada, where he gave a talk on beauty in Python last year. He started using Python in 1997 or 1998 (the exact year has been lost to history) and for 15 years has maintained the PyEphem library for amateur astronomers. He trains new Python programmers professionally, writes Python for projects like the New England Wildflower Society's new Go Botany web site, and tries to share everything he learns with the community that has given him such a great programming language for free.

As you may or may not recall, last August my article on the evils of recycling was published. Sometimes I lose sight of the fact that thousands of people read the stuff I put out there.  Other slightly more creepy individuals google my name and usually ask some sort of favour. But others actually have something interesting to say. So Ben, even though you’ll never read this, thanks for your letter. It’s not often I get to hear from the mythical ‘audience’ writers always harp on about.

Getting started
Run As... / Debug As...
Most projects can be launched by using the Run As.../Debug As... menu options:
This option is available, if your project contains a web.xml file. The launcher will automatically select the Web Application directory and launch the embedded Jetty.
Launch Configuration
To create a Launch Confiugration for your web project using Eclipse Jetty, just open to your Run/Debug configurations and click on "New launch configuration". Select the project (if it's not yet select). Usually you should be able to run and debug your project now.
WebApp Settings
The WebApp tab contains the most important options for your Jetty Launch Configuration: the project, the folder, that contains the static files and the WEB-INF directory, the path of the URL and HTTP and HTTPs ports.
When creating a new Launch Configuration the project and the Web App folder will be determined automatically. If this fails, you have to set the values manually. Select the Project (should be you WAR module) and scan or browse for the Web App folder. Eclipse Jetty works best, if you follow the Maven standard directory layout.
The Context Path is the first part of the path in the URL to access your application. If you leave it blank, it defaults to "/".
The HTTP Port usually defaults to 8080 for web applications. If you need, you can Enable HTTPs at the specified port (defaults to 8443). The HTTPs connection uses a self-signed certificate of the Jetty Eclipse Plugin, so you have to allow access to your applicatin in your browser.
Options
The Options tab contains advanced settings of your Launch Configuration. It allows you to define the Jetty versions, lets you enable features and you can add configuration files manually.
Jetty
The Jetty Eclipse Plugin comes with an integrated Jetty 8. It is tested and should work with most projects (but you will need at least Java 1.6). If you need, you can use a different Jetty installation. Download it from the Jetty homepage download section and extract it. Browse for the directory. The Eclipse Jetty Plugin will automatically detect the version of the Jetty (supported are currently 6.x - 9.x).
Jetty Features
You can enable and disable some Jetty Features manually. Usually these features are disabled for faster startup times.
Enable JSP Support
This enables support for Java Server Pages in order to let Jetty compile JSPs. If you don't need JSPs support, disable this option; you server will start faster.
Enable JNDI Support
This enables support for the Java Naming and Directory Interface. If you use this for a data source, for example, you have to specified a context file, with the data source. You will also have to mark the needed JARs as "Global" in the dependencies table. This checkbox just adds the needed JARs when launching Jetty. For more infos see the JNDI Howto.
Enable JMX Support
This enables the Java Management Extension of the JVM and adds some MBeans provided by Jetty. You can only connect to the JVM locally.
Plugin Features
The Eclipse Jetty Plugin comes with an enhanced launcher for the Jetty server (like the start.jar of your Jetty).
Enable Jetty Launch Info
When enabled, some additional information will be shown on startup. Usually this provides great help when searching for problems with dependencies:
Enable Jetty Plugin Console
When enabled, the launcher provides a console with some useful features. Just type help in your Eclipse Console and press enter.
Jetty Configuration
With the configuration options you can modify the contents of the context file.
Override Graceful Shutdown Timeout
When you shut down the Jetty server gracefully, this may need some time. If your application has a lot to do when shutting down, you can increase the timeout for this shutdown operation here.
Limit Size of Thread Pool
A Jetty server maintains a thread pool for all actions. For example, each incoming connection gets one thread from the thread pool (even if it does not get processed). With this option, you can limit the thread pool. This reduces memory consumption and debugging becomes easier.
Limit Number of Acceptors
The acceptors of a Jetty are used to process requests. If not enough acceptors are available, the request has to wait. You can limit the number of acceptors to simulate high server load or make sure, that the server does not process more requests than necessary.
Enable AJP Connector on Port
This option is reserved for a future enhancements and is currently not implemented. If you need this, or other features, you have to add the JARs of Jetty manually and mark them as "Global" in the dependencies table. Additionally you have to provide needed context files.
Custom Web Defaults XML
Before a Jetty server processes the web.xml file, it automatically loads a default file with some settings. With this option, you can override this behavior and define another defaults file.
Disable Server Cache
A Jetty server maintains a cache for static resources to increase performance. This cache usually works well and even recognizes modified files. But under certain circumstances the reload of updated files does not work. If this happens to you, you can disable the cache with this option.
Disable Client Cache
If you enable this option, the Jetty server will send a "Cache-Control: max-age=0" for each servlet request. This is great, if you are working on CSS or HTML files, as the browser reloads all files from scratch.
Jetty Context Configuration
With the context configuration, you can add additional Jetty context files to the startup process.
The table contains the default Eclipse Jetty Launcher Context. This contains the configuration of the Eclipse Jetty Plugin. Additionally you can add more context files, that are processed in the specified order. You may need this, for example, to define a JNDI data source (see JNDI Howto for an example).
Dependencies
The Eclipse Jetty Plugin divides the project libraries into two categories: the Jetty libraries and the dependencies of the project. With the settings on the Dependency tab, you can alter this behavior.
If you are using Maven for your project and you have enabled the M2Eclipse Plugin, a scope is provided for each library. With this scope you can, e.g., distinguish between dependencies for the application and dependencies for the unit tests.
In the Include Maven Dependencies settings you can globally add and remove dependencies with the specified scope. By default, only dependencies with a scope of compile or runtime get added.
If you are not using Maven, or a dependency is unknown to Maven, the library does not contain a scope. With the Include Other Dependencies option, you can add or remove these libraries. If your project uses Maven and the M2E Plugin, this option is disabled by default, otherwise it is enabled.
The table shows all dependencies/libraries of the project. You can include and exclude the dependencies with the left checkbox. For example, it is sometimes necessary, that you manually add the database driver, because the dependency is set to "provided" by Maven (which is correct for the server), but with your development Jetty you need the dependency.
By default, all dependencies are loaded with the classloader of the web application and not with the System classloader of Java. You can change this behavior by selecting the right checkbox. When enabled, the Jetty launcher will load the specified dependency with the System classloader. You may need this, e.g., for your database driver, if you define a JNDI datasource.


When you click on the 'Spider' tool a dialog will be displayed which allows you to start the spider. You will not be able to spider sites that are not in scope, but the dialog will detect that and give you the option to add the site to the scope.
When the spider is started the tool will show how far the spider has progressed. As the tutorial is very small this will not take very long at all, but it may take much longer for larger sites. The status is maintained when you navigate to different pages so you can carry on exploring the site while the spider is running. You will be able to see all of the pages that the spider has found via the Sites tree. If you click on the Spider tool while it is running then you will be given the option to stop it. You may well see alerts being raised after you start the spider as ZAP passively scans all of the URLs it finds.

ipVersion: IPVersion.v4,
name: "Client", // Optional friendly name of the Client host
deviceDiscoveryListener: MyDiscoveryListener(),
connectionListener: MyConnectionListener(),
);
// Wait for the Client to completely initialize
if(!await client.ready){
print("Could not start on Client");
return;
}
print("Client is ready. IP: ${client.ipAddress}");
// Start discovering devices
print("Discovering hosts...");
client.discoverHosts();
}
// Create listener for receiving advertisements and discovery alerts from the Server
class MyDiscoveryListener implements DeviceDiscoveryListener{

// Send message back to this client
Future.delayed(Duration(seconds: 1)).then((_) =>
client.send(Packet.from(WordPair.random().asPascalCase), device,
ignoreIfNotConnected: true)
);
}
}
Sample server_test.dart
for working with a Server:

{% extends "django_collada_base.html" %} {% block content %}
Django Collada is an open source project. It provides a simple way of working with COLLADA-models
in a Django context. It provides a way to upload zipped collada archives (ie. .dae-file and related assets) to a
Django web application that can serve the uploaded files in an accessible manner for visualisation on the client side.
In addition, the scenes can easily be set up (grids, axes, background colors etc.) using a provided configuration
object for each supported visualisation technique.
| Client technology | Django Collada Example | Grid | Axes | Movable camera |
|---|---|---|---|---|
| three.js | Example | Yes | Yes | Yes |
Django Collada can import a COLLADA file to a Django project and then serve the dae and related assets statically. The COLLADA model is not converted to a full Django persistent object by any means. We instead emply the excellent pycollada library to access the mesh in detail.
urlpatterns += (url(r'^django_collada', include('django_collada.urls')),)
django_collada
to your djangos settings.py, INSATLLED_APPS
You should extend the django_collada.models.ColladaScene model class in your own applications and go from there to create your views and logic around the collada model. Any of the visualisation examples above can be used as a starting point or may serve well for simpler applications. If you need deeper interactions with scenes, you will of course need to dive into the WebGL framework (ie. three.js) of choice.

You must be the change you wish to see in the world.
"I will give you a talisman. Whenever you are in doubt, or when the self becomes too much with you, apply the following test. Recall the face of the poorest and the weakest man [woman] whom you may have seen, and ask yourself, if the step you contemplate is going to be of any use to him [her]. Will he [she] gain anything by it? Will it restore him [her] to a control over his [her] own life and destiny? In other words, will it lead to swaraj [freedom] for the hungry and spiritually starving millions? Then you will find your doubts and your self melt away." - One of the last notes left behind by Gandhi in 1948, expressing his deepest social thought.
