> +Studio Code Debug API](https://code.visualstudio.com/docs/extensionAPI/api-debugging).
> +It can be installed as an extension for the Visual Studio Code and Nuclide IDE.
> +The protocol is easy to run remotely and also can allow other tools and IDEs to
> +get a full featured debugger with a well defined protocol.
> +
> +# Intallation for Visual Studio Code
> +
> +Installing the plug-in involves creating a directory in the `~/.vscode/extensions` folder and copying the package.json file that is in the same directory as this
> +documentation into it, and copying to symlinking a lldb-vscode binary into
> +the `bin` directory inside the plug-in directory.
> +
> +If you want to make a stand alone plug-in that you can send to others on unix systems:
> +
> +```
> +$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
> +$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ cp /path/to/a/built/lldb-vscode .
> +$ cp /path/to/a/built/liblldb.so .
> +```
> +
> +
> +If you want to make a stand alone plug-in that you can send to others on macOS systems:
> +
> +```
> +$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
> +$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ cp /path/to/a/built/lldb-vscode .
> +$ rsync -av /path/to/a/built/LLDB.framework LLDB.framework
> +```
> +
> +You might need to create additional directories for the `liblldb.so` or `LLDB.framework` inside or next to the `bin` folder depending on how the [rpath](https://en.wikipedia.org/wiki/Rpath) is set in your `lldb-vscode` binary. By default the `Debug` builds of LLDB usually includes
> +the current executable directory in the rpath, so these steps should work for most people.
> +
> +To create a plug-in that symlinks into your `lldb-vscode` in your build directory:
> +
> +```
> +$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
> +$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
> +$ ln -s /path/to/a/built/lldb-vscode
> +```
> +
> +This is handy if you want to debug and develope the `lldb-vscode` executable when adding features or fixing bugs.
> +
> +# Configurations
> +
> +Launching to attaching require you to create a [launch configuration](https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations). This file
> +defines arguments that get passed to `lldb-vscode` and the configuration settings
> +control how the launch or attach happens.
> +
> +## Launch Configuration Settings
> +
> +When you launch a program with Visual Studio Code you will need to create a [launch.json](https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations)
> +file that defines how your program will be run. The JSON configuration file can contain the following `lldb-vscode` specific launch key/value pairs:
> +
> +|parameter |type|req | |
> +|-------------------|----|:--:|---------|
> +|**name** |string|Y| A configuration name that will be displayed in the IDE.
> +|**type** |string|Y| Must be "lldb-vscode".
> +|**request** |string|Y| Must be "launch".
> +|**program** |string|Y| Path to the executable to launch.
> +|**args** |[string]|| An array of command line argument strings to be passed to the program being launched.
> +|**cwd** |string| | The program working directory.
> +|**env** |dictionary| | Environment variables to set when launching the program. The format of each environment variable string is "VAR=VALUE" for environment variables with values or just "VAR" for environment variables with no values.
> +|**stopOnEntry** |boolean| | Whether to stop program immediately after launching.
> +|**initCommands** |[string]| | LLDB commands executed upon debugger startup prior to creating a the LLDB target. Commands and command output will be sent to the debugger console when they are executed.
> +|**preRunCommands** |[string]| | LLDB commands executed just before launching after the LLDB target has been created. Commands and command output will be sent to the debugger console when they are executed.
> +|**stopCommands** |[string]| | LLDB commands executed just after each stop. Commands and command output will be sent to the debugger console when they are executed.
> +|**exitCommands** |[string]| | LLDB commands executed when the program exits. Commands and command output will be sent to the debugger console when they are executed.
> +|**sourceMap** |[string[2]]| | Specify an array of path re-mappings. Each element in the array must be a two element array containing a source and destination pathname.
> +|**debuggerRoot** | string| |Specify a working directory to use when launching lldb-vscode. If the debug information in your executable contains relative paths, this option can be used so that `lldb-vscode` can find source files and object files that have relative paths.
> +
> +## Attaching Settings
> +
> +When attaching to a process using LLDB you can attach in a few ways
> +
> +1. Attach to an existing process using the process ID
> +2. Attach to an existing process by name
> +3. Attach by name by waiting for the next instance of a process to launch
> +
> +The JSON configuration file can contain the following `lldb-vscode` specific launch key/value pairs:
> +
> +|parameter |type |req | |
> +|-------------------|--------|:--:|---------|
> +|**name** |string |Y| A configuration name that will be displayed in the IDE.
> +|**type** |string |Y| Must be "lldb-vscode".
> +|**request** |string |Y| Must be "attach".
> +|**program** |string | | Path to the executable to attach to. This value is optional but can help to resolve breakpoints prior the attaching to the program.
> +|**pid** |number | | The process id of the process you wish to attach to. If **pid** is omitted, the debugger will attempt to attach to the program by finding a process whose file name matches the file name from **porgram**. Setting this value to `${command:pickMyProcess}` will allow interactive process selection in the IDE.
> +|**stopOnEntry** |boolean| | Whether to stop program immediately after launching.
> +|**waitFor** |boolean | | Wait for the process to launch.
> +|**initCommands** |[string]| | LLDB commands executed upon debugger startup prior to creating a the LLDB target. Commands and command output will be sent to the debugger console when they are executed.
> +|**preRunCommands** |[string]| | LLDB commands executed just before launching after the LLDB target has been created. Commands and command output will be sent to the debugger console when they are executed.
> +|**stopCommands** |[string]| | LLDB commands executed just after each stop. Commands and command output will be sent to the debugger console when they are executed.
> +|**exitCommands** |[string]| | LLDB commands executed when the program exits. Commands and command output will be sent to the debugger console when they are executed.
> +|**attachCommands** |[string]| | LLDB commands that will be executed after **preRunCommands** which take place of the code that normally does the attach. The commands can create a new target and attach or launch it however desired. This allows custom launch and attach configurations. Core files can use `target create --core /path/to/core` to attach to core files.
> +
> +
> +## Example configurations
> +
> +### Launching
> +
> +This will launch `/tmp/a.out` with arguments `one`, `two`, and `three` and
> +adds `FOO=1` and `bar` to the environment:
> +
> +```javascript
> +{
> + "type": "lldb-vscode",
> + "request": "launch",
> + "name": "Debug",
> + "program": "/tmp/a.out",
> + "args": [ "one", "two", "three" ],
> + "env": [ "FOO=1", "BAR" ],
> +}
> +```
> +
> +### Attach using PID
> +
> +This will attach to a process `a.out` whose process ID is 123:
> +
> +```javascript
> +{
> + "type": "lldb-vscode",
> + "request": "attach",
> + "name": "Attach to PID",
> + "program": "/tmp/a.out",
> + "pid": 123
> +}
> +```
> +
> +### Attach by Name
> +
> +This will attach to an existing process whose base
> +name matches `a.out`. All we have to do is leave the `pid` value out of the
> +above configuration:
> +
> +```javascript
> +{
> + "name": "Attach to Name",
> + "type": "lldb-vscode",
> + "request": "attach",
> + "program": "/tmp/a.out",
> +}
> +```
> +
> +If you want to ignore any existing a.out processes and wait for the next instance
> +to be launched you can add the "waitFor" key value pair:
> +
> +```javascript
> +{
> + "name": "Attach to Name (wait)",
> + "type": "lldb-vscode",
> + "request": "attach",
> + "program": "/tmp/a.out",
> + "waitFor": true
> +}
> +```
> +
> +This will work as long as the architecture, vendor and OS supports waiting
> +for processes. Currently MacOS is the only platform that supports this.
> +
> +
> +### Loading a Core File
> +
> +Loading a core file can use the `"attach"` request along with the
> +`"attachCommands"` to implement a custom attach:
> +
> +```javascript
> +{
> + "name": "Attach to Name (wait)",
> + "type": "lldb-vscode",
> + "request": "attach",
> + "attachCommands": ["target create -c /path/to/123.core /path/to/executable"],
> +}
> +```
