;;; Commentary:
;; Javascript debugger using the chrome debug websocket protocol. Debug
;; your Javascript code directly in emacs. All the known debugger features
;; from chrome like stepping, show stack, restart frame, object evaluation,
;; file recompilation, debugging of web workers are supported.
;;
;; chrome needs to be started with following command line parameter
;; chrome --remote-debugging-port=9222
;; so that the debug port is open.
;;
;; Following interactive emacs commands are provided:
;; - chrome-connect - connect to running chrome instance
;; (use tab completion to find the tab to be debugged)
;; - chrome-disconnect - disconnect from current debug session
;; - chrome-add-breakpoint - add a breakpoint
;; - chrome-remove-breakpoint - remove a breakpoint
;; - chrome-step-into - step into
;; - chrome-step-over - step over
;; - chrome-step-out - step out
;; - chrome-continue - continue
;; - chrome-evaluate-expression - evaluate expression at current point (completion by pressing tab)
;; - chrome-show-stack - show stack list when in debugging mode
;; commands inside show stack mode:
;; - chrome-restart-stackframe - re-run stackframe at current point
;; - chrome-console-navigate - navigate to source for stackframe at current point
;; - chrome-show-console - show console
;; - chrome-recompile-file - recompiles current file and uploads to running chrome debug session
;; - chrome-disable-all-breakpoints - disable all breakpoints
;; - chrome-enable-all-breakpoints - enables all breakpoints
;;
;; Dependencies:
;; - websocket
;; - json-reformat
;; both packages can be installed via M-x package-install
;;
;; Status:
;; alpha
