Awesome Commandline Tools
summary
Shows that a production-grade CLI REPL with persistent history, case-insensitive context-aware completion, fish-style suggestions and syntax highlighting is implementable with 10 lines of Python using prompt_toolkit plus Pygments. Demos compare pgcli/mycli/dbcli, fish shell and bpython, highlight a bad MySQL default that lists 805 possibilities after FROM, and then builds an echo REPL that adds auto-suggestion from history, ctrl‑r search, emacs keybindings, completer and syntax highlighting — all working live.
