#API for trace (master branch) by Stuart Sierra, Michel Salim, Luc Préfontaine, Jonathan Fischer Friberg
The trace tool is compatible with Clojure versions 1.2.x and 1.3.
(ns your-namespace (:require clojure.tools.trace))
This file defines simple "tracing" macros to help you see what your code is doing.
#Public Variables and Functions
Current stack depth of traced function calls.
Usage: (deftrace name & definition)
Use in place of defn; traces each call/return of this fn, including arguments. Nested calls to deftrace'd functions will print a tree-like structure.
Usage: (dotrace fnames & exprs)
Given a sequence of function identifiers, evaluate the body expressions in an environment in which the identifiers are bound to the traced functions. Does not work on inlined functions, such as clojure.core/+
Usage: (trace value) (trace name value)
Sends name (optional) and value to the tracer function, then returns value. May be wrapped around any expression without affecting the result.
Usage: (trace-fn-call name f args)
Traces a single call to a function f with args. 'name' is the symbol name of the function.
Returns an indentation string based on trace-depth
Usage: (tracer name value)
This function is called by trace. Prints to standard output, but may be rebound to do anything you like. 'name' is optional.
Usage: (trace-forms & body)
This macro helps identify which nested form triggered a runtime Exception. However it will not catch compilation exceptions. If a runtime Exception occurs, the message will include a trace back of all the nested forms starting with the innermost one where the exception occurred plus the original exception message.
