That is what I meant, should have been clearer. Those reasons make sense.

I'm not sure what you mean. It does throw errors for certain kinds of
invalid grammars and other fatal problems.
Perhaps what

Hi puzzler,
I have a project https://github.com/JeremS/cljss-core/tree/v0.4.0 that I
have been meaning to be useable from Clojure and ClojureScript. To do so I
am using lein-dalap http://birdseyesoftware.github.io/lein-dalap.docs/.
I totally agree with you about the issues you have foreseen.
Hi Puzzler,
I was wondering if you planned to port Instaparse to ClojureScript. I know
it's asking a lot, but I am one of those who would love
to be able to run it in a browser or in node.js...
Cheers,
Jeremys.

Mark,
I had not heard about Java changing the substring operation from O(1) to
O(n). Do you have a link to any further info about this change?
I'm guessing that the implementation is changing from the O(1) create a
new String object that is a reference to a portion of the original String
object
And to answer my own question about a reference for this change in
behavior, which appears to have been made in Java 7:

Hello Mark,
I have few suggestions:
1. I was going through the tutorial and comparing EBNF and ABNF grammars.
ABNF adds Bounded Repetition 3*5 A. Is there any chance of adding it also
to EBNF? I don't know, how the syntax would be, but it can be useful at
times.
Repetition of characters can be
EBNF syntax for bounded repetition could be just simply A 3*5 and these are
equal:
A? is A*1
A+ is A1*
A* is A0*

Right now, in the EBNF syntax, numbers are valid non-terminal identifiers.

Large bounded repetition is a theoretical question. My use case requires to
ensure repetition of only small number of digits - one digit, two digits
and similar. I would use bounded repetition to ensure the needed number of
digits. Yes, different workarounds will work for me, so it is not a

Instaparse is an easy-to-use, feature-rich parser generator for Clojure.
The big idea behind instaparse is to make it simple to convert grammars to
parsers without needing to know the idiosyncrasies of LL1, LALR, and other
esoteric grammar restrictions imposed by most parser generators.

Hi Puzzler,
Instaparse seems to be a wonderful piece of software congrats ! I haven't
had the time to test it yet but
it's on the top of my to do list.
Cheers

PS This is kind of a fan boy message but congratulations really seem to be
in order nonetheless :)
