LOL,
yep, the third is Exactly the meaning
DAMN, I should have called it fluid ... not liquid... now I know why everyone is mislead(strangely
that was almost the case).
thanks for the support Ingo ;-)
No, really, liquid stems its name from the term "data flow"... I wanted to make it have
its own language so that once assimilated, when following a discussion or especially
writting about the relationship a liquid object (or valve) has with the rest of the code,
it is clear.
when you say "the valve is connected to your object" there is absolutely no ambiguity.
One is live, the other isn't.
It also stems from the fact that in previous versions of liquid.r there was a base object
called container.
consider the next phrase:
"filling liquid into a container through a pipe", this makes a lot of sense and deftly
resumes exactly what is happening.
you can thus continue by "if a valve is open, it spills liquid"
This being the actual event (or action), depending on what is connected to the valve,
will either splash data to the user or silently put it in the container (an object's
attribute?), for later reference.
I'm sorry this means the methods and attributes have their own "world" but if you think
of it, many other programming things have borrowed names from real world items...
By looking at the liquid-vid tutorials,
http://www.rebol.it/~steel/liquid-vid/tutorials.html
Most things about liquid are explained in enough detail, I hope. I have not received
one comment on them. either no one went, or those that did, found it clear enough for
their understanding (I hope its the later ;-).
I understand Robert and Gregg, and I sympathise, but sooo much tought went into it (including
other things not yet available) that I feel, its too late.
Once you use it a little, you'll see that there isn't alot of words to actually learn
and even then, they really are obvious. On top of that, within a liquid-vid block, pretty
much only the connect and attach words are needed.
I hope that the naming won't keep people from trying it out and understanding the concept.
I'm hard at word every other night, hacking away at code that eventually, I hope, you'll
all benefit from, much like vanilla, rugby, and make-doc-pro and all the others cool
tools. I can't wait for all my tools to be v1.0 but there is soooo much to do.
Right now, I am working on the v1.0 of open-library which allows of us to package our
code as shared modules. Much like python has a standard code sharing system.
Soooooo stay tuned, it won't be long before I submit it for all of us to tear at, bitch
about, improve, and eventually adopt.
have fun!
