Description
A framework for creating shell envinronments.
Description
Shellac is a framework for building read-eval-print style shells. Shells are created by declaratively defining a set of shell commands and an evaluation function. Shellac supports multiple shell backends, including a basic backend which uses only Haskell IO primitives and a full featured readline backend based on the the Haskell readline bindings found in the standard libraries. This library attempts to allow users to write shells at a high level and still enjoy the advanced features that may be available from a powerful line editing package like readline.
