"""Code generator for Ozone platform list.
This script takes as arguments a list of platform names and generates a C++
source file containing a list of those platforms.
Each platform gets an integer identifier that is used to find objects for that
platform (particularly constructors for platform-specific objects).
Example Output: ./generate_ozone_platform_list.py --default wayland dri wayland
// platform_list.txt
wayland
dri
// platform_list.h
#ifndef UI_OZONE_PLATFORM_LIST_H_
#define UI_OZONE_PLATFORM_LIST_H_
namespace ui {
const int kPlatformWayland = 0;
const int kPlatformDri = 1;
extern const char *kPlatformNames[kPlatformCount];
} // namespace ui

namespace ui {
const char *kPlatformNames[] = {
