Crate yash_semantics 

Semantics of the shell language.

This crate defines the standard semantics for the shell language. The core of the semantics is command execution and word expansion. A command can be executed by calling Command::execute. A word can be expanded by using functions and traits defined in expansion.

The read_eval_loop reads, parses, and executes commands from an input. It is a utility for running a shell script.

Deprecation

The re-export of yash_env::semantics::command::search as command_search is now deprecated. Please use command::search instead.
