  NOTE this doesn't really check if a specifier is entirely valid in order to highlight
  for example if you have %lls we highlight it
  we simply check each subspecifier in order to see if it seems valid and move on and don't have logic to see if 
  the subspecifiers are comptaible or not
  we don't highlight if any of the subspecifier checks fail so if you do %.qd we don't highlight it 
  Also I commented out some checks that I wasn't sure if they were invalid in c++ but valid in C or ones that I just never use

  Instructions 
  In 4coder_draw.cpp there a function draw_cpp_token_colors() that decides what color to draw tokens and draws them.

Case study: Get dark command windows all the time in Windows

TL;DR

1. Make a copy conhost.exe from System32.
2. Open it with a hex editor (I use HxD).
3. In HxD, go to Search - Find - Hex-values.
4. Search for 881d9e530a004885c07477ff15b32e08009084c0.
5. In Windows 10 version 2004, replace ff15b32e0800 with 909090909090. If using Windows 10 version 20H2, replace ff15b32e08009084 with 9090909090909090.
6. Save file and copy it back to System32 (take ownership of original conhost.exe in order to replace it).
7. Profit!

Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++ / OOP or (other) obscuring cruft. View on YouTube

M68000 Peephole Optimizations

TODO

Sources to go through:

• asp68k peephole optimizations: Not all are real.
• Efficient 68000 Progamming: Probably some overlap with the above.
• 68000 Tricks and Traps
• A couple 68k tricks
