vroom - Fast reading of delimited files

•    C++

---

The fastest delimited reader for R, 1.27 GB/sec. vroom doesn’t stop to actually read all of your data, it simply indexes where each record is located so it can be read later. The vectors returned use the Altrep framework to lazily load the data on-demand when it is accessed, so you only pay for what you use. This lazy access is done automatically, so no changes to your R data-manipulation code are needed.

Simplecsv - CSV parser for Java, based on the OpenCSV

•    Java

---

A simple library for parsing CSV in Java, based on the OpenCSV library. After trying unsuccessfully to fix some of the key bugs in OpenCSV, I concluded that the core of the library -- the CSVParser -- was too complicated a patchwork to salvage. I decided to rewrite it. That effort led to forking the project entirely, with the primary intent of simplifying the parser code, but keeping it fast and generally in the spirit of the OpenCSV library.

csv-schema - Analyzes a CSV file and generates database table schema, all within the browser

•    Javascript

---

This application parses CSV files (including huge ones) within the browser. It analyzes each field to suggest the best database field type, max length, and whether or not there are any null values. From there, you can rename fields, ignore them, override field types/lengths, etc. and generate database table creation sql for MySQL, MariaDB, Postres, Oracle, or SQLite3. This application uses PapaParse for CSV parsing and Knex.js for SQL query building.

Detect.js - :mag: Library to detect browser, os and device based on the UserAgent String

❗️ NOTE: THIS PLUGIN IS NO LONGER MAINTAINED. If you encounter a bug then you're probably on your own. Try Bowser as an alternative. Note: Detect.js is a JavaScript library to detect platforms, versions, manufacturers and types based on the navigator.userAgent string. This code is based on, and modified from, the original work of Tobie Langel's UA-Parser: https://github.com/tobie/ua-parser. UA-Parser is subsequently a port of BrowserScope's user agent string parser.

readr - Read flat files (csv, tsv, fwf) into R

•    R

---

The goal of readr is to provide a fast and friendly way to read rectangular data (like csv, tsv, and fwf). It is designed to flexibly parse many types of data found in the wild, while still cleanly failing when data unexpectedly changes. If you are new to readr, the best place to start is the data import chapter in R for data science. To accurately read a rectangular dataset with readr you combine two pieces: a function that parses the overall file, and a column specification. The column specification describes how each column should be converted from a character vector to the most appropriate data type, and in most cases it's not necessary because readr will guess it for you automatically.
