Less than 200 lines, properly cross platform, actually outputs error
messages if things break, better flag handling. Everyone has
Python anyway.

# Handmade Math 2.0 Update Tool
Due to the large number of breaking naming changes in Handmade Math 2, we provide a small tool to update your programs automatically. It's a C program that takes a list of files and updates their text, along with some scripts to recursively run the program on all code in a directory.
Due to the large number of breaking naming changes in Handmade Math 2, we provide a small Python script to update your programs automatically. It can run on individual files or on all files in a directory (recursively).
You can compile the tool yourself with any C/C++ compiler:
**Warning!** This tool is not very smart! Please ensure that your work is committed and backed up, in case you have to revert this tool's changes.
```bash
# MSVC (Windows)
cl update_hmm.c
# gcc
gcc update_hmm.c -o update_hmm
# clang
clang update_hmm.c -o update_hmm
```
# see usage info and options
> python3 update_hmm.py -h
usage: update_hmm [-h] [--exts .foo [.foo ...]] filename [filename ...]
...
Once built, the tool can be run on any C or C++ files:
# run on individual files
> python3 update_hmm.py MyPlatformLayer.c MyPlatformLayer.h
Updating: MyPlatformLayer.c
Updating: MyPlatformLayer.h
Updated 2 files with 0 warnings.
```bash
# Windows
update_hmm.exe MyGame.cpp MyPlatformLayer.cpp
# Other platforms
update_hmm MyGame.cpp MyPlatformLayer.cpp
```
Or, update all C/C++ files in a directory by running one of the provided shell scripts:
```bash
# Windows
update_hmm_all.bat "path\to\project"
# Other platforms
update_hmm_all.sh path/to/project
# run on a whole directory
> python3 update_hmm.py projects/MyCoolGame
Updating: projects/MyCoolGame/src/MyPlatformLayer.c
Updating: projects/MyCoolGame/include/MyPlatformLayer.h
...
```
