1. Preprocessor
I am writing a preprocessor for eu.
It will do much of the same stuff as PP, only it will have support for
classes and structures.
If anyone has any other ideas for it, please say.
Thanks,

I started a preprocessor project about 1 year ago, called idEu. It
implements classes, structs, macros, goto, more loop flow control
statements, a select/case construct, plus about 30 to 40 additional
features. Still got a couple of them to test and debug, the others
respond correctly in short code snippets.
As I'm currently working an another language (OpenEuphoria)
documentation, this was stalled for a few months. Hope to complete this
project though.
Testing and rewriting the yet uninspected code may take 1 month. After
that, there's a doc to write (nothing was done yet)
and test on a largish scale project to perform, as
interaction between features may be tricky sometimes and short snippets
won't catch the subtle bugs. Could release Q3, 2004.
If you want to help, that's very much welcome.

Bach has those. Don't jump me about promoting Bach tho, not yet... I am
just thinking there is a lot of duplication going on here. Afaik, there are 3
alternate languages based to some degree on Eu, and the designers of
those 3 are not talking to each other, and not collaborating, combining
energies? Granted Bach and Eu are closed proprietary projects we cannot
get into, but i wonder if Bach is so much more advanced now that it bears
only a glancing resembalance to Eu. But maybe it is a lot like your OpenEu.

Whacha need? Atm, i am writing a debugger for Bach, but i am not involved
in the development of it, so some of my wish list is still unrealised...
Actually, i am not good with windows gui programming, so my debugger will
prolly come out as dos, if i get no help. If i do, then Bach will have a windows
gui debugging environment, with ability to change the contents of variables
from the gui at runtime. And trace options, etc.. Karl cannot sell such a thing
for Bach, if he is basing his interpreter on Eu, but i assume i can, Rob? Or
give it away? It's debug only, and isn't for a production codebase, that is to
say, the debug commands embedded in the code will not be recognised by
Bach itself.

I would be willing to help - I need some sort of stable project. What can I
do to help?
By the way, I've stalled the preprocessor at the moment, I only started it
because I was bored.

I hope that every feature will be working in the expected way by March-April
2004. Then
- there's no docs atm
- The project won't be tested in a large scale (2k-4k lines) project, and this
is (I think) the only way to catch feature interaction bugs before they spread.
If I perform both of these, I'm afraid that would be a 6 month effort. If
somebody else has a bit more free time than I, it would help.
I can send you the progress sheet I use to remember what works and what
doesn't privately if you wish, so that you get an idea of what will be
provided. The main program file is about 5500 lines of text, from which
800-1000 are comments. There aren't enough comments.

6. Preprocessor
Hello All,
I have a question about David Cuny's preprocessor. I'm experimenting with
it for some time now and recently I dl'ed version .51. I like the way it
works, especially to make programs with many sequences, loops and
for..then..elsif.. etc constructions more readable.
My question, however, concerns the "case" statement. The documentation says
that you can use an <expression> in the select clause, so I tried:
sequence s
s = {}
select case numeric length(s) do
case 0
-- empty
case else
-- not empty
end select
This does not work. The expression length(s) is translated to a single ')'.
I could not find a reference to this kind of 'bug', or isn't it a bug?
Is it just impossible what im trying?
Ad Rienks.
PS I find it pityfull to see people quarrelling on this server. If someone
comes with arguments, try to answer to the arguments, and not to what you
think the other is implying. Sometimes it is difficult, I know by my own
experience, but since you're not face to face, first think and than answer.
Or maybe you shouldn't answer at all, if you think the arguments are
silly.

*** Reply to note of 01/22/97 13:31
it's a bug, all right. that's the fix that 0.51b takes care of. instead of
writing something like:
arg = append( arg, token[i] ) -- accumulate the tokens
i wrote:
arg = token[i] -- duh. this discards everthing but the last token.
and it didn't show up until i tried a more complex expression. the update
was posted this morning.
sorry for the inconvenience.
you'll also notice that i changes the style of the formatting from:
if
test ...
elsif test ...
end if
to:
-- case <expression>
if test...
elsif test...
end if
let me know if you prefer one format over the other.
thanks.

Hello David,
As a follow-up of my 'bug-report', I looked into the official Euphoria page
and downloaded your version .51b. I see you have also come across this bug
and fixed it. Thanx!
Don't bother to answer; you must be way too busy writing new attachments to
your preprocessor! Good Luck and keep up the good work.
Ad Rienks
