Function Documentation

mutt_parse_rc_line_cwd()

enum CommandResult mutt_parse_rc_line_cwd	(	const char *	line,
		char *	cwd,
		struct Buffer *	err
	)

Parse and run a muttrc line in a relative directory.

Parameters

line	Line to be parsed
cwd	File relative where to run the line
err	Where to write error messages

Return values

CommandResult

Result e.g. MUTT_CMD_SUCCESS

Definition at line 145 of file command_parse.c.

{
  mutt_list_insert_head(&MuttrcStack, mutt_str_dup(NONULL(cwd)));
 
  enum CommandResult ret = mutt_parse_rc_line(line, err);
 
  struct ListNode *np = STAILQ_FIRST(&MuttrcStack);
  STAILQ_REMOVE_HEAD(&MuttrcStack, entries);
  FREE(&np->data);
  FREE(&np);
 
  return ret;
}
