BBEdit is designed for use by software developers and web designers. It has native support for many programming languages and custom modules can be created by users to support any language. BBEdit is not a word processor, meaning it does not have text formatting or page layout features.
The application contains multi-file text searching capabilities including support for Perl-compatible regular expressions. BBEdit allows previewing and built-in validation of HTML markup and also provides prototypes for most HTML constructs that can be entered into a dialog box. It also includes FTP and SFTP tools and integrates with code management systems. BBEdit shows differences between file versions and allows for the merging of changes. Support for version control, including Git, Perforce, and Subversion is built in.
