Description

CotEditor is specifically designed for macOS and aligns perfectly with the expectations of macOS users. Its rapid launch time ensures that you can begin writing without delay whenever inspiration strikes. As an open-source project, CotEditor invites contributions from anyone interested in enhancing its capabilities. It supports syntax highlighting for over 50 popular programming languages, such as HTML, PHP, Python, Ruby, and Markdown, while also allowing users to create personalized settings. The interface enables you to split the window into several panes, facilitating the simultaneous view of various sections of your document. You can easily inspect the Unicode character data of any selected character, which is displayed conveniently in a popover. There is no need for complicated configuration files requiring technical expertise; all your settings, including syntax definitions and themes, can be managed through a straightforward preferences window. With CotEditor, the worry of losing unsaved changes is eliminated, as it automatically backs up your work during editing sessions. Additionally, it provides a feature to identify and list characters in your document that cannot be converted to the desired encoding, ensuring a smooth writing experience. This combination of user-friendliness and powerful features makes CotEditor a valuable tool for writers and developers alike.
