[so] BUG in parser??

[Daniel Avieritei]

Pe bash arata cam asa:

bash-2.05b# ls g$HOME
ls: g/root: No such file or directory

bash-2.05b# ls $HOME/s
ls: /root/s: No such file or directory

bash-2.05b# ls g$HOME/s
ls: g/root/s: No such file or directory


pt comanda:  "ls g$HOME/s "

n-ar trebui sa am ceva de genul:
command (NULL,NULL, scmd1, 0)
scmd1(null, null,null, words1,0)
words1("ls", 0, null, words2);
words2("g",0,part1,null);
part1("HOME",1",part2,null);
part2("/s", 0, null,null);
?


Cu urmatorul program de test:
int main (void) {
	while(1) {
		printf("# ");
		yyparse();
		if ( command != NULL ) {
			printf("%s-s-s", command->scmd->words->next->string);
		}
	}
	return 0;
}

Obtinem:

Aici n-ar trebui sa fie HOME???
