SASqlConsole is a unified SQL console based on SQLAlchemy. It features pretty colors, intelligent formatting of output, convenient CSV output, a consistent interface across all backends supported by SQLAlchemy, persistent readline history, and tab completion of all tables and columns and a selection of SQL keywords.
Essence is a compact console editor. It is a fork of Ersatz Emacs, the smallest of the microEmacs forks. It carries on the Ersatz author's pursuit of minimalism by accepting all code submissions which either shrink the binary without loss of functionality or add features without increasing the size of the binary. Periodic calls for new features without size limitation are made to keep the project alive.
