set-break-handler 函数

Usage: (set-break-handler!)
       (set-break-handler! f)

Register INT signal handler.  After calling this, Ctrl-C will cause
the given function f to be called with a single argument, the signal.
Uses thread-stopper if no function given.

source宏

Usage: (source n)

Prints the source code for the given symbol, if it can find it.
This requires that the symbol resolve to a Var defined in a
namespace for which the .clj is in the classpath.

Example: (source filter)

source-fn函数

Usage: (source-fn x)

Returns a string of the source code for the given symbol, if it can
find it.  This requires that the symbol resolve to a Var defined in
a namespace for which the .clj is in the classpath.  Returns nil if
it can't find the source.  For most REPL usage, 'source' is more
convenient.

Example: (source-fn 'filter)
