Function Documentation

create_heredoc()

int create_heredoc

(

char *

delimiter

)

Creates a here-document file and gathers input.

Creates a temporary file for a here-document, gathers input for it by calling get_input(). Returns a file descriptor to the created file.

Parameters

delimiter

The delimiter that signals the end of the here-document.

Returns

The file descriptor of the created here-document, or -1 on error.

get_input()

bool get_input	(	int	fd,
		char *	delimiter
	)

Reads input for a here-document until a specified delimiter.

Reads input from the user, displaying a prompt, until the specified delimiter is entered. The input is written to the given file descriptor. Also handles ctrl-d (end-of-file from readline).

Parameters

fd	The file descriptor to write the input to.
delimiter	The delimiter that signals the end of the here-document.

Returns

True if successful, false on error.

open_inputfile()

bool open_inputfile	(	t_executor *	current,
		t_lexer_list *	lexer
	)

Handles opening an input file.

Handles opening an input file for the given t_executor node, based on the given lexer list token type. It supports input redirection and here-document.

Parameters

current	A pointer to the current t_executor node.
lexer	A pointer to the current t_lexer_list node.

Returns

True if the file is opened successfully, false on error.
