*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

"""This spawns a sub-shell (bash) and gives the user interactive control. The
|
|
entire shell session is logged to a file called script.log. This behaves much
|
|
like the classic BSD command 'script'.
|
|
|
|
./script.py [-a] [-c command] {logfilename}
|
|
|
|
logfilename : This is the name of the log file. Default is script.log.
|
|
-a : Append to log file. Default is to overwrite log file.
|
|
-c : spawn command. Default is to spawn the sh shell.
|
|
|
|
Example:
|
|
|
|
This will start a bash shell and append to the log named my_session.log:
|
|
|
|
./script.py -a -c bash my_session.log
