A Programming Language Database

View this readme as HTML

PLDB is a public domain ScrollSet and website containing over 135,000 facts about over 4,000 programming languages.

This repo contains the entire ScrollSet, code, and website for https://pldb.io.

To download the data

The entire ScrollSet is ready to analyze in popular formats. Full documentation is here: https://pldb.io/csv.html

// npm install pldb console.log(require("pldb").javascript.appeared)

To add a new language

Create a new Scroll file in concepts with a unique URL friendly filename and send a pull request.

To update a language

Edit the corresponding concepts/*.scroll file and send a pull request.

To add a new measure

Update the file code/measures.parsers and add at least 1 measurement to a concept in concepts and send a pull request.

To build the site locally

git clone https://github.com/breck7/pldb cd pldb # Required to run this during first install only. npm i -g cloc # Required to run this on fresh checkout and when upgrading from an old checkout or periodically when there are new releases npm install . # (Optional) Run tests npm run test npm run build # After you make changes and before you commit make sure to run: npm run format
