Parser

Recursive descent parser producing an AST from tokens.

Recursive descent parser producing an AST from tokens.

The parser validates syntax (grammar checks) and builds a tree of t_ast nodes via recursive descent.

• Pipelines are left associative: (cmd1 | cmd2) | cmd3
  
• Redirections wrap commands from outermost to innermost and are reversed after construction for left-to-right execution order
