My try on identifying line types using Python re named groups 
what became a quite unreadable line, also missing ```, sorry.


line.py
    import re, sys
    for line in sys.stdin:
        m = re.match(r'((?P<heads>(?P<h3>###)|(?P<h2>##)|(?P<h1>#))|(?P<list>\* )|(?P<link>=> (?P<url>[^\s]+))|(?P<quote>>))\s*(?P<content>.*)$', line)
        if m:
            print(m.groupdict())

example.gmi
    # Heading of Level One
    ## Heading of Level Two
    ### Heading of Level Three
    ###Heading of Level Three Tight
    ####Heading of Level Three with starting hash
    #### Heading of Level Three with starting hash and space
    * list item
    *  list item spacey
    *   list item spaceous
    => http://example.org/no/name
    => http://example.org/with/name Linkname
    >Quote Tight
    > Quote Nice
    >>Quote starting with gt
    >>> Quote starting with two gts
    End
