Status: Closed

Where does the ignore come from? The artificial token or from the the stream? Need to record this info and use it during backtracking
<pre>
lex start
{
ignore /[ \t]+/
literal '*', '(', ')', '^', ';', '\n', '.'
token id /[a-zA-Z_]+/
}
parser out_parser [out]
global out_parser Out = construct out_parser []
def out_item
[id]
| ['(' item* ')']
def out
[out_item*]
def item
[id]
{
Out << r1
}
| ['(' item* ')']
{
# Out << '('
# Out << r2
# Out << ')'
}
def A1 []
def A2 []
def F
[]
{
#Out.finish()
}
def start
[A1 item* F '.' '^']
| [A2 item* F '.' ';' '\n']
start Input = parse start( stdin )
print( Input )
</pre>
