clojure.tools.trace - tools.trace 0.7.12-SNAPSHOT API documentation

Full namespace name:

This file defines simple tracing macros to help you see what your code is doing.

Protocol to isolate trace-form from convoluted throwables that 
do not have a constructor with a single string argument.

clone-throwable attempts to clone a throwable with a human readable stack trace
and message :)
It must return a throwable of the same class. If not clonable, the original
throwable should be returned. At least this will preserve the original 
throwable information.

Cloning should be non-obtrusive hence internal exceptions should be silently
swallowed and return the original throwable.

Known implementations:

Usage: (clone-throwable this stack-trace args)

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.
The first argument of the form definition can be a doc string

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-forms & body)

Trace all the forms in the given body. Returns any underlying uncaught exceptions that may make the forms fail.

Usage: (trace-ns n)

Trace all fns in the given name space. The given name space can be quoted, unquoted or stored in a var.
We must try to resolve the expression passed to us partially to find out if it needs to be quoted or not
when passed to trace-ns*

Usage: (trace-vars & vs)

Trace each of the specified Vars.
The arguments may be Var objects or symbols to be resolved in the current
namespace.

Usage: (traceable? v)

Returns true if the given var can be traced, false otherwise

Usage: (traced? v)

Returns true if the given var is currently traced, false otherwise

Usage: (untrace-ns n)

Untrace all fns in the given name space. The given name space can be quoted, unquoted or stored in a var.
We must try to resolve the expression passed to us partially to find out if it needs to be quoted or not
when passed to untrace-ns*

Usage: (untrace-vars & vs)

Untrace each of the specified Vars.
Reverses the effect of trace-var / trace-vars / trace-ns for each
of the arguments, replacing the traced functions with the original,
untraced versions.
