Macro (add a debugger macro)¶
macro macro-name lambda-object
Define macro-name as a debugger macro. Debugger macros get a list of arguments which you supply without parenthesis or commas. See below for an example.
The macro (really a Python lambda) should return either a String or an
List of Strings. The string in both cases is a debugger command. Each
string gets tokenized by a simple split() . Note that macro processing
is done right after splitting on
;;. As a result, if the macro
returns a string containing
;; this will not be interpreted as
separating debugger commands.
If a list of strings is returned, then the first string is shifted from
the list and executed. The remaining strings are pushed onto the command
queue. In contrast to the first string, subsequent strings can contain
;; in those strings will be split into separate
Here is an trivial example. The below creates a macro called
which is the same thing as
macro l= lambda: 'list .'
A simple text to text substitution of one command was all that was needed here. But usually you will want to run several commands. So those have to be wrapped up into a list.
The below creates a macro called
fin+ which issues two commands
finish followed by
macro fin+ lambda: ['finish','step']
If you wanted to parameterize the argument of the
finish command you
could do that this way:
macro fin+ lambda levels: ['finish %s' % levels ,'step']
would expand to:
['finish 3', 'step']
If you were to add another parameter for
step, the note that the
invocation might be:
fin+ 3 2
fin+ 3, 2.
