What is a .CR file?
A .CR file is a type of file that contains source code written in the Crystal programming language. This programming language is used by developers to write instructions for computers to perform specific tasks. The content inside a .CR file is a set of these instructions, which need to be processed by a special program called a compiler (specifically, the Crystal compiler) to be turned into a form that the computer can execute.
To view or modify the contents of a .CR file, you can use a source code editor. These are programs designed to help programmers write and edit their code efficiently. Some of the popular source code editors that can open .CR files include: 1. **Microsoft Visual Studio Code** - A widely used editor that supports many programming languages, including Crystal. 2. **GitHub Atom** - Although this editor has been discontinued, it was previously a popular choice for editing various types of code. 3. **GNU Emacs** - A very powerful and customizable editor that can be used for programming in Crystal as well. 4. **Any text editor** - Simple text editors like Notepad on Windows or TextEdit on macOS can also open .CR files, but they won't offer features specifically for programming.
Additionally, if you prefer working online, there are Crystal Online Playgrounds available on the web. These platforms allow you to write, edit, and test Crystal code directly in your internet browser without needing to install any software on your computer.
