1. Compiler questions
I am about to start writing a compiler which I hope will be as easy to
use as Euphoria but generate executables that run at asm speed. This
project seems quite ambitious (though that never stopped me before) and
I would like to get some views from the list on the following questions.
I have some opinion about most of them but a variety of concisely
expressed arguments will help me definitely
decide each point.
Regards,
Mike
1. What sort of numerical data types should be there? Only integer
(signed 32-bit) and real (double precision floats)?
2. Can restrictions be placed on bitwise operations with real types?
3. Would 1-d arrays and lists of character strings be enough?
4. Should it support cdecl?
5. Type conversion - implicit or explicit?
6. Pass by reference - when is this needed?
7. What sort of notation could be used to access arrays? structures?
8. Forward references?
9. Control structures other than: if, for, while ?
10. Error recovery?
11. Anything else?

To Bernie:
I guess I didn't up it to RDS since NQA, in it's current state, isn't really
useful for any serious programming. Release 3 might be, whenever it'll be
finished.
Resources sounds like an interesting idea. I haven't looked into how they
work myself.
To Mike:

Should be enough.
>3. Would 1-d arrays and lists of character strings be enough?
Could be a bit tedious with not n-dimensional in real-world applications.
>4. Should it support cdecl?
Why not? It's not "harder" than stdcall in any way, just different.
>5. Type conversion - implicit or explicit?
Explicit for speed, implicit for elegance, i suppose.
>7. What sort of notation could be used to access arrays? structures?
[] for arrays and . for structures are the most common.
>8. Forward references?
Sure.
>9. Control structures other than: if, for, while ?
Switch-case maybe.
>11. Anything else?
COFF object/library compliance.

To answer your questions you first have to tell us, what you want to do
with the new compiler.
Maybe:
If it is used near machine-code you will need many bit-operations
if it is used for web applications you will need many control
structures.
there are already C-compilers which produces fast code
dont invent a new one
easier to use is for example the xbasic-compiler. It makes
assembler-code.
but it already exists.
Maybe the world needs something like a fast java-compiler ?
Euphoria was invented because of the idea with the new datastructures.
when you create an EU-compiler which produces code which is twice as
fast ...
You should have a new idea and then implement it in a compiler.
Maybe the world needs somthing like rpg in the big IBM-machines for=20
running on a pc and is freeware. it would help to write fast and secure
commercial applications.

Or how about an EuphoriaToAsm translator?
