Shell language syntax and parser
This crate defines data types for constructing abstract syntax trees (AST)
of the shell language. See the syntax module for details.
Some AST elements (e.g. Word) provide a
location where the element appears in the source code.
See the source module to learn how locations are coded in this crate.
To parse source code into an AST, you can use the parse function on a
&str, which is enabled by the implementations of
FromStr for the AST data types. However, ASTs
constructed this way do not contain very meaningful source information: All
locations’ source will be unknown. To include
substantial source information, you need to prepare a
lexer with source information and then pass it to a
parser. See the parser module for details.
The input module defines an abstract method for feeding the parser with
source code.
This crate also defines the alias module that can be used to define
aliases that are recognized while parsing.
