reverse_redir_chain()

t_ast* reverse_redir_chain

(

t_ast *

node

)

Reverse a redirection chain for left to right execution order.

The parser builds redirections with the outermost being last, so this reverses the chain so that the first parsed redirection is outermost, matching BASH's left to right behavior

Parameters

node	Outermost redirection

Returns

New outermost node of the reverse chain

join_connected_delim()

char* join_connected_delim	(	t_token **	tokens,
		int *	quoted
	)

Join connected tokens in a single string.

• Walks the connected tokens, accumulating their values
• Sets quoted to 1 if any token in the chain was quoted

Parameters

tokens	Pointer to current token pointer
quoted	Set to 1 if any was quoted

Returns

Joined string or NULL on allocation failure
