Imagine if instead of constantly switching back and forth between editing and running your code, you could see the results of your code running live as you write it? Potion is an application that shows a live preview of your code running right beside your editor, so you can tell if your program is working instantly.
Potion is a REPL tool. Programming with a REPL has a rich history (the shell itself is a form of REPL), but they've never reached their full potential. Traditionally they've required entering code at a plain command prompt, a difficult proposition for programmers today accustomed to "richer" editing environments. Potion changes all that by making the REPL accessible alongside how programmers are already the most comfortable working: Writing code in a text editor and checking it into version control.
- OS-level file-system events to keep the preview up-to-date, so use Potion with VS Code, Atom, Sublime Text, TextMate, BBEdit, Vim, Emacs, or any other text editor.
- No configuration or special file formats, so Potion works seamlessly with existing projects, workflows, and version control systems, like git, svn, and Mercurial.
