1. Borrowing from Perl for namespace
Hi all, just wanted to throw out some ideas to consider...
In Perl 5.0, which I just started learning not too long ago, there are
these things called packages (kinda like classes in C++), and the way you
access their methods/data is by using '::', just like in C++.
So if you had 2 packages, named 'p_one' & 'p_two', which both had the
same scalar named $count, then you could access them both using:
$p_one::count
$p_two::count
without the interpreter or yourself getting confused (or getting an
error).
In Euphoria, we could make it so that each .e files' routines/data are
accessed by using 'include_name::stuff'. That way there could be a bunch
of variables by the same name, but they are not confused with each other
because of the 'include_name::' prefix.
Example:-----------------------------
include normal.e
include color.e
sequence text
text = "Hi there"
normal::show(1,text)
color::show(1,text,"blue","yellow")
--------------------------------------
This could also be used for DLLs (which I believe someone else mentioned
before?):
--------------------------------------
include crypt32.dll
sequence text
puts(1,"Enter your text to be encrypted")
text = gets(0)
text = crypt32::encrypt(text,"1234")
--------------------------------------
Being able to simply include a DLL like a .e file would be a whole lot
easier to do than open_dll() & define_c_whateverw(). It would make the
whole DLL interface easier to use, especially for newbies (like moi) ;)
...but would make the core language a little more bloated :(
This introduces the use of something like 'use' or Visual Basic's 'with':
with crypt32 do
encrypt(text,"1234")
end with
the 'with' construct would eliminate the 'dll/include::' prefix
if you plan to use the same include file in a block. Nesting might be a
problem though...
Of course, if you're big on Euphoria's individuality, then this is not
for you, because it would just cause Euphoria to be associated with
C++... :)
