Re^6: hrm, Eval::Compile

Like Corion said, the key to implementing this design is delay :) Perl does it

$ perl -c -e " foo(1); "
-e syntax OK
[download]

Even though foo() isn't defined yet, perl recognizes it as a function yet to be defined by the syntax(like your tags), so it holds off reporting an error as long as possible (runtime, when it tries to call it)

$ perl -e " foo(1); "
Undefined subroutine &main::foo called at -e line 1.

H.O.P is all about this approach, build a tree, walk the tree, modify the tree, compute

The computable things are defined by syntax < > [ ] ( ), whether they'll actually compute or be returned verbatim is delayed until runtime

Like perl, TT2 takes the approach that if its not computable, its an error, not a string substitution

Your blind spot seems to be your current implementation -- you keep thinking in terms of substitution s/// instead of function/method calls -- even s/// is not really substitutions, its a series of function/method calls -- each call to s/// is a walk of the tree (flat tree, a string)

Oh how I wish I was a 17 year old whizz kid again... I'd have it coded up in no time. At 31 I feel 900 years old, burnt out, clapped out, one foot in the grave, someone please do me a favour and shoot me in the head. Ok, at the risk of really dumb, (like I haven't already), how do I build said "tree". I get what it is conceptually, but I'm thinking like a multi-level hash table solution? Is that a million miles from the answer? Oh how easy using n-dimensional arrays and fixed point math to do 3d graphics was back in the day... lol	[reply]

H.O.P chose Array of Arrays because arrays are already ordered and perl is very good at manipulating lists and arrays; you should chose AoA so you can leverage H.O.P. , HOP::Lexer, HOP::Parser	[reply]

Argh, more learning... can't I just pay someone to do it? Oh yeh that's right I got no money because I've spent the last 8 years goofing off and going down a code tangent all by my merry self. Bah.... Actually I quite like arrays :) I think I can picture roughly how the solution is going to work, now, where did I put that text editor program... It's gotta be here somewhere... mumble mumble	[reply]
