1 Description

Experimental integrated visual debugger using Debug Adapter Protocol.

Debug Adapter Protocol is a wire protocol for communication between client and Debug Server. It similar to the LSP but providers integration with debug server.

1.1 Layer installation

To use this configuration layer, add it to your ~/.spacemacs. You will need to add dap to the existing dotspacemacs-configuration-layers list in this file.

1.2 Features:

Fully featured IDE-like debugger providing:

  • Launch/Attach
  • Breakpoints
  • Exceptions
  • Pause & Continue
  • Step In/Out/Over
  • Callstacks
  • Threads
  • Multiple simultaneous debug sessions
  • Evaluating statements
  • Debug/Run configurations
  • Debug REPL

2 Configuration

2.1 Derived layers

Derived layer should provide information how to configure the language specific debug adapter and the language specific bindings(e. g. debug application, debug test, etc). The package declares function spacemacs/dap-bind-keys-for-mode which should be used by the derived layers to configure the shortcuts.

2.1.1 Declared prefixes

The following prefixes have been declared:

prefix name
SPC m d debug
SPC m d d launching
SPC m d b breakpoints
SPC m d l debug windows
SPC m d S context switching
SPC m d e eval
SPC m d I inspect

2.1.2 Default key bindings

The default bindings are listed below. Derived layers should extend this list:

Key binding Description
SPC m d d d start debugging
SPC m d d l debug last configuration
SPC m d d r debug recent configuration
SPC m d c continue
SPC m d i step in
SPC m d o step out
SPC m d s next step
SPC m d v inspect value at point
SPC m d r restart frame
SPC m d . debug transient state
SPC m d a abandon current session
SPC m d A abandon all process
SPC m d e e eval
SPC m d e r eval region
SPC m d e t eval value at point
SPC m d S s switch session
SPC m d S t switch thread
SPC m d S f switch frame
SPC m d I i inspect
SPC m d I r inspect region
SPC m d I t inspect value at point
SPC m d b b toggle a breakpoint
SPC m d b c change breakpoint condition
SPC m d b l change breakpoint log condition
SPC m d b h change breakpoint hit count
SPC m d b a add a breakpoint
SPC m d b d delete a breakpoint
SPC m d b D clear all breakpoints
SPC m d '_ Run debug REPL
SPC m d w l list local variables
SPC m d w o goto output buffer if present
SPC m d w s list sessions
SPC m d w b list breakpoints
