8 years ago I have no particular loyalty to Prototype; it was just the framework I happened
to have already learned at the time I was developing Canviz. If I switch Canviz
from Prototype to jQuery, that might make you happy, but displease those
already using Canviz with Prototype. And there may be others wanting to use
MooTools or another framework.
For maximum interoperability, I would like for Canviz to not require any
JavaScript framework, but I'm not sure how best to do that. There are features
Canviz uses which aren't built into JavaScript. For example, Canviz uses
Prototype's class-based object inheritance model; this fit more easily into my
brain than JavaScript's default prototype-based object model. Also, I want to
dynamically load additional JavaScript files as needed (see issue #20), and I
assume that Prototype and other frameworks offer a function to do that, and
that it would be tedious to do manually. Canviz already uses other Prototype
conveniences which are tedious to do manually, but in the interest of
decreasing framework dependence, I'm willing to forgo those conveniences, if
they can be replicated without bloating the code too much.
Any work on reducing Canviz's framework dependence should also consider the
Path library, which Canviz uses. There was a patch submitted to remove the
Prototype dependency from Path, in response to this discussion thread:
http://groups.google.com/group/canviz/browse_thread/thread/ae7ff77d60825bf3/6974
cc25e2255948 The patch was submitted to me privately by Frank Hess, but I will
attach it to this ticket now. I did not apply it at the time because it made
many different changes at once, and was hundreds of lines long, making it hard
for me to review. He said:
"I made the following changes:
"- Classes created using closures where possible
"- changed Object.isUndefined() -> ===undefined
"- changed the prototype each constructs to for loops
"There is only one function call I'm unsure: In line 42 (this.reset();) - I
commented it out."
So the reset issue needs to be addressed, and the patch needs to be evaluated
by someone who has a thorough understanding of both class-based and
prototype-based object models who can determine if Canviz still works the way I
programmed it to after these changes. I would also want each logical change
committed separately: for example, all instances of changing
"Object.isUndefined()" to "=== undefined" would be one commit, changing all
Prototype "each" constructs to "for" loops would be a second commit, and so on.
How do other JavaScript libraries deal with this problem? Do they offer a
choice of frameworks (if so, how do they accomplish that?) or do they just
write everything themselves?Original comment by ryandesi...@gmail.com on 13 Jun 2011 at 7:44
