[lldb-dev] help for lldb command like gdb info sources & info source

[Greg Clayton]

For this old of an LLDB you will need to put back ticks around the $pc:

(lldb) image lookup -va `$pc`

To get the file list, we can turn to python:

Import the above file and then run the new "info_sources" command:

(lldb) command script import /tmp/sources.py
The "info_sources" command has been installed, type "help info_sources" or "info_sources --help" for detailed help.
(lldb) info_sources a.out
Module: /Volumes/work/gclayton/Documents/src/args/a.out
  /Volumes/work/gclayton/Documents/src/args/main.c

Checkout the python and then head to:

to see the rest of the API you have available to you
