Through the use of Google Translate and my pea-sized brain I translated all of the variables and custom blocks to english and also micro-optimized a few things. This is just the standalone STeX engine. I was originally going to use this for my upcoming project, but I found a cheaper and faster alternative, so I decided to release this on its own for those who might want it.
All of the code is by @SQY419 I just translated the custom block and variable names and changed a bunch of divisions to multiplications. I'll update if I find more stuff.
