mholt/PapaParse

Papa Parse is a JavaScript library for parsing and generating CSV data in both browser and Node.js environments. It supports streaming, chunking, and worker threads for handling large files, along with features like pausing/resume and skipping initial lines. The system also includes an unparse function to convert data back to CSV format and provides a demo interface for testing various parsing configurations.

This change introduces the initial commit for version 5.7.0 of Papa Parse, establishing the core library files (papaparse.js, papaparse.min.js) and build infrastructure (Gruntfile.js, .eslintrc.js, bower.json). It adds the \downloadTimeout\ configuration option to abort slow remote requests, implements \skipFirstNLines\ to skip initial lines before parsing, and exposes \renamedHeaders\ in the parse result metadata to track duplicate header mappings. The release also removes the optional jQuery plugin integration, strips the UTF-8 Byte Order Mark (BOM) from header column names, and corrects the quoting and escaping of custom quote characters during unparsing.

The player directory now includes a complete demo interface (HTML, CSS, and JavaScript) for testing Papa Parse. This page allows users to configure parsing options such as streaming, chunking, worker threads, and fast mode. It introduces new capabilities including the ability to pause and resume parsing via the step and chunk callbacks, support for skipping the first N lines, and a new 'Unparse' button that converts data back to CSV format. The demo also integrates jQuery 3.5.1 and provides visual controls for delimiters, line endings, and file uploads.

Added a comprehensive test suite for PapaParse, including Node.js-specific tests (node-tests.js) and browser tests (tests.html with Mocha/Chai). The suite covers core parsing, streaming, pause/resume functionality, and error reporting, supported by sample CSV files (long-sample.csv, verylong-sample.csv, etc.) and an ESLint configuration for the tests directory.

This change introduces the package.json manifest for PapaParse version 5.7.0, establishing the project's npm configuration. It defines the library as a CSV parser with a main entry point of papaparse.js and a browser-specific build of papaparse.min.js. The manifest includes a set of development dependencies required for the build and test process, specifically chai, connect, eslint, grunt, grunt-contrib-uglify, mocha, mocha-headless-chrome, open, and serve-static. It also configures npm scripts for linting, building, and running tests in both Node.js and headless Chrome environments.
