The `lldb-vscode` tool creates a command line tool that implements the [Visual
Studio Code Debug API](https://code.visualstudio.com/docs/extensionAPI/api-debugging).

If you want to make a stand alone plug-in that you can send to others on unix systems:
|**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.
+|**terminateCommands** |[string]| | LLDB commands executed when the debugging session ends. 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.
|**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.

|**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.
