Swift Terminal Fuzzy Finder

tui-fuzzy-finder is a fzf style text UI fuzzy finder library in Swift. It lists the contents of a asynchronous stream in the terminal, one item per line. The user can select one or multiple items from the list and use fuzzy search to filter the list, and when they press return, tui-fuzzy-finder returns the list of the selected items.

Demo

Why

fzf is a fantastic tool, but if you're not into shell scripting, it can be be a drag. This library aims to provide the core functionality of fzf in a Swift library, so you can write your tools in Swift.

What is included

tui-fuzzy-finder consists of a Swift library and an executable, sfzf, that uses it. The purpose of sfzf is to make it easy to excercise the tui-fuzzy-finder features that are difficult to test automatically. It does not try to compete with fzf.

Documentation

Documentation is available at the Swift Package Index.

Command line usage

To build and install the executable run swift build -c release, then copy .build/release/sfzf somewhere on your path.

Run sfzf --help to get information about command line arguments.

While the program is running:

• Move up and down with arrows
• Edit the filter line with normal line-editing commands
• Toggle selection with tab
• Press return to exit and write the selected lines to stdout

Goals

• Sufficient coverage of fzf features.
• Fast enough.

Stretch goals

• Good platform coverage. PRs are welcome where it falls short.

Non-goals

• Replacing fzf as a shell tool.
• Supporting the fzf features that only make sense in the shell scripting context.
