BBEdit is a professional HTML and text editor from Bare Bones Software Inc., aimed at web and software developers. Features include pattern matching (“grep”); search and replace across multiple files; the ability to edit columns (in “delimited (CSV, TSV) text files”); function navigation and syntax coloring for numerous source code languages; code folding; text and code completion; FTP and SFTP open and save; AppleScript support and a “text factory”; Unix scripting support and a complete set of HTML markup and clean-up tools.
Version 13 was a major update, first released last fall, that includes “Pattern Playgrounds … for learning, developing and testing regular expression search patterns (‘grep patterns’) in a safe environment” and “live display of both literal and regular expression matching while entering a search string in the Find window”, plus an “Apply Transform command, which provides a powerful, immediate means to apply any single text transformation to multiple files and folders”, among many other improvements.
BBEdit 13.0.3 is priced at $49.99 for macOS 10.14 and later. The BBEdit download runs for 30 days with all features enabled for evaluation and then continues with a reduced feature set free of charge. (The free BBEdit mode replaces BBEdit’s earlier TextWrangler app.)
TextMate is a “powerful and customizable text editor” for the Mac from MacroMates Ltd. with support for “a huge list of programming languages”, HTML markup, and general use.

MacVim is an enhanced version from Björn Winckler and others of the widely used text editor with its old Unix user interface that predates modern, graphical Macintosh “apps.” In fact, Vim is included in the macOS Unix command-line libraries accessible via Terminal, and MacVim may best serve as a training ground for learning Unix-style editing. Features from Vim include a bullt-in tutorial and a highly customizable/extensible environment, along with comparison and merging of files, extended regular expressions, scripting languages, network support, spell-checking, Unicode support, syntax highlighting, undo/redo history, and quite a bit more. (See the MacVim FAQ and reference manual for more details.)
MacVim 8.1.1722 (157) is freely downloadable charity-ware for OS X 10.8 and later, and Vim also runs on Windows, Linux, VMS, and other operating systems.
