C++ Here

Parses competitive programming problems and sends them to C++ Here.

Send a problem's sample tests to the C++ Here online editor with one click. No more copying and pasting. WHAT IT DOES Open a problem on an online judge and click the toolbar button (or press Ctrl+Shift+U, ⌘+Shift+U on Mac). The editor opens with every example input and output already loaded as a test case. Write your solution, press "Run All", and each one runs on its own and is checked against the expected answer. Passing ones turn green. WHY INSTALL IT • Save time: three or four examples mean six to eight copy-and-paste trips. Now it is one click. • No pasting mistakes: everything is read straight from the page, down to the trailing newline. • Works on more than 100 websites, including Codeforces, AtCoder and CSES. The full list is on GitHub (link below). • Works for contests too: on a supported contest page, import the whole contest at once. • No compiler to install: you write, run and check your code right in the browser. MORE FEATURES • A tab that is already open is reused instead of opening a new one. If it already has test cases, you are asked whether to replace them or add the new ones. • On a page that isn't recognized automatically, right-click the toolbar button and choose from the "Parse with" menu. • Custom rules in the options let you always use a specific parser for URLs that match a pattern. PRIVACY • The extension reads a page only when you click its button, press its shortcut, or choose from its menu. • It contains no analytics or tracking code, and it never reads your browsing history, form fields, passwords or cookies. • What it reads goes only to the editor tab in your browser. The extension does not send it to any server. OPEN SOURCE Open source under the MIT license, based on Competitive Companion by Jasper van Merle.
