pylavi 0.1.0

Python LabVIEW File Parser

pylavi

Python LabVIEW resource file parser

Description

This project was inspired by pylabview by mefistotelis (which was originally forked from pylabview by jcreigh). The idea was to reverse engineer the LabVIEW VI file format. This project is designed to be a reboot, taking the incredible discovery done by the pylabview projects and simplifying the structure of the code.

This starts with a conceptual model of the LabVIEW resource file and treats the binary resources files as just collections of resources. Once the API for working with the file format itself is solidified, then code can be added to work with resources of specific types.

Along the way discoveries will be documented.

Using to validate VIs

Install

pip3 install pylavi

Validate VIs

vi_validate --path lv_source --no_beta --gt 21.0

usage: vi_validate [-h] [-l LT] [-g GT] [-e EQ] [-r] [-b] [-a] [-d] [-i] [-p PATH] [-s SKIP] [-x EXTENSION] [-q]

Validates LabVIEW resource files

optional arguments:
  -h, --help            show this help message and exit
  -l LT, --lt LT        LabVIEW version must be less than this
  -g GT, --gt GT        LabVIEW version must be greater than this
  -e EQ, --eq EQ        LabVIEW version must this
  -r, --no-release      LabVIEW version must not be release
  -b, --no-beta         LabVIEW version must not be beta
  -a, --no-alpha        LabVIEW version must not be alpha
  -d, --no-development  LabVIEW version must not be development
  -i, --no-invalid      LabVIEW version must be a valid phase
  -p PATH, --path PATH  Path to scan for files (or a file path) (defaults to current directory)
  -s SKIP, --skip SKIP  Path to not scan for files (or a file to ignore)
  -x EXTENSION, --extension EXTENSION
                        File extensions to evaluate (defaults to all known)
  -q, --quiet           Reduce the output (multiple times reduces output more)
