We also add a very basic yapf configuration file. Most of the changes in this patch were performed automatically, but we broke one overly long string into multiple components on `src/make_dbg_constants.py`.

# Build the DebugCmdConstants.h and DebugCmdInfoConstants.cc files from the
|
|
# DebugCmdInfoConstants.in file.
|
|
#
|
|
# We do this via a script rather than maintaining them directly because
|
|
# the struct is a little complicated, so has to be initialized from code,
|
|
# plus we want to make adding new constants somewhat less painful.
|
|
#
|
|
# The input filename should be supplied as an argument.
|
|
#
|
|
# DebugCmds are printed to DebugCmdConstants.h
|
|
# DebugCmdInfos are printed to DebugCmdInfoConstants.cc
|
|
#
|
|
# The input format is:
|
|
#
|
|
# cmd: [DebugCmd]
|
|
# names: [space delimited names of cmd]
|
|
# resume: ['true' or 'false': should execution resume after this command?]
|
|
# help: [some help text]
|
|
#
|
|
# Blank lines are skipped.
|
|
# Comments should start with // and should be on a line by themselves.
