parse_powerisa_pdf/README.md

parser for the OPF PowerISA 3.1C pdf to attempt to extract all instructions' pseudo-code including subscripts/superscripts and other formatting

Usage:

• Download the OPF PowerISA 3.1C pdf (yes you need that exact version) from https://openpower.foundation/specifications/isa/

• Obtain CPython 3.11 (the default python3 in Debian Bookworm)

  On Debian Bookworm you can do:

  sudo apt update
  sudo apt install python3-venv
  

• Create a venv:

  python3.11 -m venv --upgrade-deps path/to/your/new/.venv
  

• Activate the venv:

  . path/to/your/new/.venv/bin/activate
  

• Install this project in the venv:

  pip install -e .
  

• Run it:

  parse_powerisa_pdf path/to/downloaded/OPF_PowerISA_v3.1C.pdf > out.log
  

• This will spit out lots of errors and then successfully create the output file -- powerisa-instructions.xml in the current directory.
