Hi,
I think one of the neatest features of Factor is being able to
dynamically reload vocabularies and have the changes immediately show up
in running code.
Now, it seems this behavior is not really magic but relies on some
explicit coding. (I vaguely remember seeing some git commits related

Hi,
There's a word add-definition-observer in compiler.units that lets
you register an object to have its definitions-changed method called
whenever definitions are added or changed. You can look at
tools.deprecation for a simple example of how it works.
Thanks, this works great.

Your code looks fine. The problem was just that GLSL-SHADER: and GLSL-

from the old definitions when they redefined a shader or program

I wrote a program to crack a linear-congruential (LC) encryption system. The
system is called LC53 (my invention), and it uses these constants:
unity = 2^32-5
mult = 2^32-3
LC encryption is fairly easy to crack, so nobody uses it in practice, but it
makes for a good test of a language
Hi Hugh,
Your program looks for a file named
C:\\Users\\hugh\\Desktop\\Factor\\factor\\work\\LC53\\test.txt
Can you send me such a test file?

Hi,
Regarding style, there's a time word in tools.time that takes a
quotation and runs it. It performs gc before calling the quotation and
prints out the time and various stats about gc. You can also press
CTRL+T in the ui listener to call it. It should remove the need to
write words like

Thanks! BTW, does that supplant the other form that also binds

Yeah. I renamed the old private words.
Anyway, I'll need to look at this later -- I got most of the way

I've finally written some documentation for the peg.ebnf vocabulary.
This documents the various ways of using it (EBNF:, [EBNF ... ENBF]
and EBNF ... EBNF) as well as the syntax for the EBNF language. Let
me know (or provide patches!) if I left anything out or if anything is
badly written.
