case statement parsing?

[panwlodek]

It looks like, that bashlex has problems with parsing of case statements. Please try read following into parser.parse:
case "$1" in
start)
start
;;

    stop)
        stop
        ;;
     
    *)
        echo $"Usage: $0 {start|stop}"
        exit 1

esac

I have following error message:
Traceback (most recent call last):
File "ttt.py", line 12, in
trees = parser.parse(s)
File "/home/joe/.local/lib/python3.10/site-packages/bashlex/parser.py", line 610, in parse
parts = [p.parse()]
File "/home/joe/.local/lib/python3.10/site-packages/bashlex/parser.py", line 691, in parse
tree = theparser.parse(lexer=self.tok, context=self)

raise NotImplementedError('type = {%s}, token = {%s}' % (type, p[1]))

I hope, you can help here.
Best regards
