Package Control: Install Package

or clone into your sublime Packages directory (If you are on Sublime Text 3 use the st3 branch)

Getting Started

This project attempts to match Visual Studio Code's Debugger fairly closely so their documentation can be pretty helpful. See


This project comes with some pre-configured debuggers (They can be installed using

Debugger: Install adapter

  • Open the debug panel

    • from the command palette
      Debugger: Open
  • Install a debug adapter by running:

    Debugger: Install adapter
    from the command palette.
  • Add a configuration

    Debugger: Add Configuration
    from the command palette (or add one manually, see below).
    • Configurations are added to
      in project settings and use the same configuration format as Visual Studio Code
    • Consult the debugger specific documentation links above for creating a configuration for your debugger. Most debuggers come with some configuration snippets to choose from but I highly recommend looking at the documentation for the debugger.
  • Your configuration will look something like the following but with some debugger specific fields.

    "debug.configurations" : [
        "name" : "Name of your configuration",
        "request" : "launch"|"attach",
        "type" : "debugger name",
  • Start debugging

    • click the gear icon to select a configuration to use
    • click the play icon to start the debugger or run
      Debugger: Start
      (if no configuration is selected it will ask you to select or create one)


Settings can either be set at the project level or globally. Project settings can be changed by appending

to the setting name.

Within a

file -
Open the debugger automatically when a project that is set up for debugging has been opened -
scales the entire debugger UI

Within a

file settings object -

for a full list of settings see debugger.sublime-settings


  • Look in the debug console for errors (usually red)
  • Look in the sublime console for errors
  • Try the same configuration/adapter in Visual Studio Code (There is a good chance your issue is with the adapter so check out the outstanding issues for it)
