If your Bash prompt still feels like it belongs in 2005, with no syntax highlighting, no fuzzy history search, and just a blinking cursor, Flyline can modernize it in about 30 seconds.
I’ve used Readline for as long as I’ve used Bash, which is most of my adult life. It always worked, so I never really thought about replacing it.
That changed when a colleague shared his terminal during a screen-sharing session. I noticed his shell highlighted a broken pipe in red before he even pressed Enter, and he could fuzzy-search through his command history as easily as searching messages in Slack.
That immediately caught my attention, so I asked what he was using. It turned out to be Flyline, a lightweight plugin written in Rust.
