CotEditor
macOS / Productivité
CotEditor is a light-weight, neat, yet powerful text editor designed for editing plain-text files such as web pages (HTML, CSS), program source codes (Python, Ruby, Perl, etc.), structured texts (Markdown, Textile, TeX, etc.), or any other kind of plain-text.
Just For Mac
The application is exactly made for macOS. CotEditor looks and behaves just as macOS applications should. It means, you already know how to use it even on the first launch. There are no complicated setting files that require geek knowledge so that you can access all your settings including syntax definitions and themes from a standard settings window.
Quick, Easy, and Powerful
CotEditor launches so quickly that you can write your text immediately when you want to. It's perfect for you to write a draft version of your document or a scratch code. The simply organized user interface doesn't disturb your task. However, at the same time, CotEditor is neither software only for beginners nor a typical minimal “zen-style” editor. It is fully customizable. There are, of course, syntax highlighting for various languages, find and replace with the regular expression, auto-indentation, command-line tool, and lots of other deep functions. You can also easily write your own macro in your favorite languages.
Key Features
• Syntax highlighting including more than 50 preset languages
