## What it is
percol is an interactive filtering tool for UNIX shells that reads lines from stdin, lets the user interactively select/filter them, and outputs the selection to stdout. It is written in Python, highly customizable, and supports Migemo-based matching for fast Japanese input filtering.

## Use cases
- interactively filter command output in a shell pipe
- search and select zsh shell history interactively
- interactive pgrep/pkill to pick processes to kill
- select tmux sessions or windows interactively
- fuzzy-select lines from a file in the terminal
- filter Japanese text with Migemo or pinyin matching

## When to choose
- you want an interactive grep-style selector embedded in UNIX pipelines
- you need heavy customization of prompts, keymaps, and colors via a Python rc file
- you frequently filter Japanese input and want Migemo/pinyin support

## When to avoid
- you want the fastest or most actively maintained fuzzy finder - prefer fzf or peco
- you need a GUI or non-terminal interactive selector
- you require guaranteed long-term support - the project has no formal license file and slow release cadence
