Summary:
This patch removes the "//----" frames and "///" leading lines from
docstring comments. We already have code doing transformations like this in
modify-python-lldb.py, but that's a script I'd like to remove. Instead
of running these transformations everytime we run swig, we can just
perform equivalent on its input once.
This patch can be reproduced (e.g. for downstream merges) with the
following "sweet" perl command:
perl -i -p -e 'BEGIN{ $/ = undef;} s:(" *\n) *//-----*\n:\1:gs; s:^( *)/// ?:\1:gsm; s:^ *//------*\n( *\n)?( *"):\2:gsm; s: *$::gsm; s:\n *"\):"):gsm' scripts/interface/*.i
This command produces nearly equivalent python files to those produced
by the relevant code in modify-python-lldb.py. The only difference I
noticed is that here I am slightly more agressive in removing trailing
newlines from docstring comments (the python script seems to leave
newlines in class-level docstrings).

SBBreakpoint supports breakpoint location iteration, for example,
|
|
|
|
for bl in breakpoint:
|
|
print('breakpoint location load addr: %s' % hex(bl.GetLoadAddress()))
|
|
print('breakpoint location condition: %s' % hex(bl.GetCondition()))
|
|
|
|
and rich comparison methods which allow the API program to use,
|
|
|
|
if aBreakpoint == bBreakpoint:
|
|
...
|
|
|
|
to compare two breakpoints for equality."
