fzf-tab-completion

It leverages fzf's fuzzy matching within native shell completion systems, providing intuitive search without replacing them, as evidenced by its support for zsh, bash, and readline apps like Python and Node.js.

Offers extensive configuration via zstyles in zsh and environment variables in bash, allowing for custom previews, keybindings, and display colors, with examples in the README for git and file previews.

Works across various shells and REPLs, including Python, PHP, R, and sqlite3, enhancing productivity in diverse terminal workflows without requiring separate tools for each environment.

Supports custom preview commands like showing file contents or git status during completion, adding contextual information that standard completion lacks, as detailed in the zstyle configuration examples.
