cgrep provides many of the features of grep, egrep, and fgrep with enhanced performance along with many additional features. One of the most important features is the ability to output the context (surrounding lines) of the matching lines. The context window may be specified as a constant number of lines before and after the matching lines, by specifying beginning and ending delimiters, or various combinations thereof.
Evergreen is a cross-platform development environment that tries to be lightweight and language-agnostic yet functional. It started as a project to reimplement Rob Pike's Acme editor for Plan 9 in Java, but has since evolved in directions that help it deal with large codebases and multiple projects/branches at once. Remaining similarities include the tiled windows and the Unix-like reliance on external programs rather than reinventing every wheel. The major philosophical differences include strong support for keyboard-based editing, language-specific functionality, and native platform UI conventions. There are also two new guiding principles: accepting regular expressions and output diffs.
