5.4.2 Debug Key Bindings

The standard debugging key bindings are always available by default on the prefix key C-c C-d, so, for example, setting a breakpoint is done with C-c C-d C-b, and compiling a source file with C-c C-d C-c. You can also easily configure IDLWAVE to use one or more modifier keys not in use by other commands, in lieu of the prefix C-c C-d (though these bindings will typically also be available; see idlwave-shell-activate-prefix-keybindings). For example, if you include in .emacs:

(setq idlwave-shell-debug-modifiers '(control shift))

a breakpoint can then be set by pressing b while holding down shift and control keys, i.e., C-S-b. Compiling a source file will be on C-S-c, deleting a breakpoint C-S-d, etc. In the remainder of this chapter we will assume that the C-c C-d bindings are active, but each of these bindings will have an equivalent shortcut if modifiers are given in the idlwave-shell-debug-modifiers variable (see Lesson II---Customization). A much simpler and faster form of debugging for running code is also available by default; see Electric Debug Mode.

User Option: idlwave-shell-prefix-key (C-c C-d)

The prefix key for the debugging map idlwave-shell-mode-prefix-map.

User Option: idlwave-shell-activate-prefix-keybindings (t)

Non-nil means debug commands will be bound to the prefix key, like C-c C-d C-b.

User Option: idlwave-shell-debug-modifiers (nil)

List of modifier keys to use for additional, alternative binding of debugging commands in the shell and source buffers. Can be one or more of control, meta, super, hyper, alt, and shift.
