Hi all,

I'm struggling with a small parser using PetitParser2. Here is a fragment of some of the rules I'm defining but their behaviour is not as I could expect:

andKeyword := 'and' asPParser trim, #letter asPParser not.
notKeyword := 'not' asPParser trim, #letter asPParser not.
keyword := andKeyword / notKeyword.

nonKeywordIdentifier := keyword not, #letter asPParser, #word asPParser star.

word := nonKeywordIdentifier, #blank asPParser star.
words := word star.

The behaviour of the "nonKeywordIdentifier" is the expected:

identifier end parse: 'hello'. "It parses successfully"��

identifier end parse: 'and'. "It fails as 'and' is a keyword"

However the "words" rule's behavior is the following:

words end parse: 'hello Pharo'. "It parses successfully"��

words end parse: 'hello and bye'. "It parses, when I would expect it fails because of 'and' is a keyword"

I don't understand why the "words" rule works this way, but I'm starting with PetitParser. Any suggestions?

Thank�� you.
