Hawk is a command-line text processor that brings Haskell expressions to shell pipelines.
It’s aimed at jobs that sit between quick one-liners and full Haskell programs, making it easier to filter, reshape, and transform line-oriented or tabular text from the terminal. When expressions start to grow, reusable logic can be moved into a user-configurable prelude file instead of being crammed into a single command.
This is free and open source software.
Key Features
- Transforms text from the command-line using Haskell expressions.
- Designed for use in UNIX pipelines and shell workflows.
- Supports both whole-input transformations and per-line mappings.
- Can work with whitespace-delimited text, custom field delimiters, custom record delimiters, or raw ByteString input.
- Lets users extend commands with helper functions, imports, and language pragmas through a configurable prelude file.
- Well suited to filtering and reorganising collections of strings arranged as lines or tables.
