Ctags

List of all kind symbols that can be extracted

$ ctags --list-kinds=C++
c  classes
d  macro definitions
e  enumerators (values inside an enumeration)
f  function definitions
g  enumeration names
l  local variables [off]
m  class, struct, and union members
n  namespaces
p  function prototypes [off]
s  structure names
t  typedefs
u  union names
v  variable definitions
x  external and forward variable declarations [off]
$

Create a classes_and_functions file with all class and function symbols for all *.cpp files located in the current directory:

$ ctags --language-force=C++ --C++-kinds=cf -o classes_and_functions *.cpp
$ cat classes_and_functions

Note the kind of symbol at the end of each line.

Camel case to snake case

def convert(name):
    s1 = re.sub('(.)([A-Z][a-z]+)', r'\1_\2', name)
    return re.sub('([a-z0-9])([A-Z])', r'\1_\2', s1).lower()

Docker image with everythind bundled

Here is a Dockerfile you can use to create a Docker image providing every tools required:

FROM ubuntu:16.04

RUN apt-get update \
 && apt-get install -y ctags wget xz-utils python \
 && wget http://releases.llvm.org/4.0.1/clang+llvm-4.0.1-x86_64-linux-gnu-debian8.tar.xz \
 && xz -d clang+llvm-4.0.1-x86_64-linux-gnu-debian8.tar.xz \
 && tar xf clang+llvm-4.0.1-x86_64-linux-gnu-debian8.tar
