Working stepper for ABCL as a contrib!

Some characteristics:

  • For intepreted code, it won't step into compiled code
  • It is ready to use from a plain REPL and from SLIME.
  • ':?' will help a minimal help
  • Can inspect variables and symbols in the current package with 'i'
  • ':c' will resume the evaluation until the end without the stepper
  • ':s' will resume the evaluation until the next form to be analyzed
  • ':sn' will to step to the next form
  • case-insensitive when inspecting
  • ':l' will print the local bindings
  • ':q' will skip the current stepping evaluation and return NIL
  • ':b' will add a breakpoint to a symbol to use with next (n)
  • ':r' will remove an existent symbol breakpoint to use with next (n)
  • ':d' will remove all existent symbol breakpoints to use with next (n)
  • ':w' allows to watch a symbol binding
  • ':u' allows to (un)watch a symbol binding
  • ':bt' shows the current backtrace

fix

  • Property svn:eol-style set to native
  • Property svn:keywords set to Id
