BBEdit

BBEdit is a professional HTML and text editor for macOS suitable for writers, Web authors and software developers, with comprehensive features for editing, searching, and manipulation of text, including grep pattern matching, search and replace across multiple files, project definition tools, function navigation and syntax coloring for numerous source code languages, code folding, FTP and SFTP open and save, AppleScript, macOS Unix scripting support, text and code completion, and a complete set of robust HTML markup tools.

Note: BBEdit starts with a free 30 day trial of is full “pro” features, then reverts to a never-expiring “free” mode, which is comparable to – and replaces – their previous freeware TextWrangler product.
