include-local-variables-in-backtraces

Arguments: ide-configuration

An IDE user option that controls whether backtraces in the debugger will show local variables, in addition to the function arguments that are always shown.

Typically you would toggle this option by pressing the button for it in the toolbar at the top of a backtrace pane. The button has an uppercase L on it, and appears depressed when the option is on.

Alternately you can set the value programmatically, such as with this form that would turn the option on:

(setf (ide:include-local-variables-in-backtraces
        (cg:configuration ide:*ide-system*))
      t)

When you "open" the item for a function call in a backtrace by clicking its arrow icon on the left (or pressing the right arrow key), only the arguments that were passed to the function will be shown when this option is off. When it is on, the local variables (mostly from let bindings) are also shown after the arguments.

This option if off by default, though prior to release 10.0 local variables were always shown.
