Trampoline

Trampoline is a lldb module that loads .lldbinit files depending on current active target.

Motivation

Sometimes you might have breakpoints, watchpoints, or additional lldb commands in your .lldbinit that don't fit for your current executable or don't fit your current architecture. Trampoline will load additional .lldbinit files according to your current executable and architecture.

File name scheme

Trampoline will search for .lldbinit files named: [executable.lldb, executable-arch.lldb] per default within the same directory trampoline.py is in.

E.g. your executable is named example and you are running lldb on a x86_64 machine. Trampoline will search for example.lldb (used for architecture independent lldb commands) and example-x86_64.lldb (lldb commands that only work on that specific architecture) and load them if available.

Installation

Copy the trampoline.py file somewhere onto your machine and insert into your ~/.lldbinit file following line:

# ~/.lldbinit
command script import /path/to/your/trampoline.py

Search path

Per default, Trampoline is searching for *.lldb files within the directory where trampoline.py is located. To change the search path insert into your /.lldbinit file following line:

# ~/.lldbinit
script trampoline.lldb_files_search_path = '~/your/new/search/path/lldb'

Disable automatic *.lldb file loading

Currently there seems to be a bug within lldb which prevents Trampolines automatic execution on startup, if lldb is run via terminal, if executed in Xcode everything works as usual.
To temporarily bypass this unexpected behaviour you can disable automatically loading of .lldb files via

# ~/.lldbinit
script trampoline.disable_automatic_load = True

Commands

Commands avaiable after enabling Trampoline.

tr_load

To manually load *.lldb files during a lldb debug session, you can enter tr_load into your lldb command line interpreter, which loads the desired *.lldb files as described in File name scheme.
