pdl-hl stands for Python Data Library Highlighter and it supports custom syntax highlighting for .pdl files in VSCode depending on your color theme.
The only thing pdl-hl does is syntax highlighting and pdl language support once installed it should automaticly highlight within the .pdl file. If not press Ctrl + Shift + P to pull the command pallete up then type change langauge mode and search pdl then press Enter keywords, comments, types and doc-strings are highlighted.
pdl-hl is syntax highlighting for Python Data Librarys so its recommended python 3.11 is installed to use the created .pdl files in programs it is also good to have the PDL pypi package
This is the one and only release there will ever be of pdl-hl there are no live updates unless I get bored and return to this project for a 'revamp'. The syntax of pdl is made to be simple so this extension is not complicated at all, just simple highlighting however my python package pdlparse will continue to get updates periodically.
