Sayid debugger

Sayid, pronounced "siy EED", is an omniscient debugger and profiler for Clojure.

Sayid works by intercepting and recording the inputs and outputs of functions. It can even record function calls that occur inside of functions. The user can select which functions to trace. Functions can be selected individually or by namespace. The recorded data can be displayed, queried and profiled.

Sayid currently has three components:

  • core and its supporting namespaces
  • nREPL middleware
  • an emacs-cider nREPL client
Key Binding Description
SPC m d b instrument expression at point
SPC m d e display last stacktrace
SPC m d r reload namespaces
SPC m d v inspect expression at point

Sayid is optional part of the Clojure layer

Sayid is an optional package in the Clojure layer for Spacemacs.

To enable sayid, add the following :variable to the clojure layer in .spacemacs

     (clojure :variables
              clojure-enable-sayid t)

The Sayid debugger library is automatically included when you run the REPL, , ' or , s i.
