choose

choose is a small text-selection CLI for pulling fields or character ranges from each input line with slice-like syntax. It is built for quick shell pipeline work on whitespace-separated, delimiter-separated, or regex-split text.

• Extract specific columns or ranges from command output, logs, and flat files without writing short awk programs.
• Slice from the front or back of each line with open-ended ranges, negative indexes, and reverse ranges when you need tail fields or reordered spans.
• Split on whitespace, literal delimiters, or regex separators, and switch to character-wise slicing for fixed-width text.

• Streams stdin or file input without prompts, so it composes cleanly in shell pipelines and inspect/transform loops.
• Output is plain text only, with no JSON or schema awareness, so downstream automation still depends on delimiters or additional parsing.
• Best when an agent needs to reshape ad hoc line output from other CLIs; less compelling once the upstream tool already exposes structured data.

• Line-oriented only: it does not understand CSV quoting, headers, or nested structured formats.
• Selection is its whole scope; filtering, aggregation, and richer transforms still belong to more expressive text or data processors.
