Re: IDE feature
Lee has a valid point. Lee's point is: let me decide. Put paredit in, but let me turn it off if I want. I agree that paredit is the only sane way for me and for anyone who doesn't have Lee's muscle memory to overcome. But for Lee, paredit is 'doing it wrong', because he doesn't enjoy it and he's unproductive that way. And that trumps any particular language, tool, paradigm, what-have-you. I mean, there are some people who are perfectly productive and happy in C++. If that's possible, then anything is :-) On Thursday, August 8, 2013 4:58:32 AM UTC+2, Lee wrote: > > > On Aug 7, 2013, at 2:06 PM, Norman Richards wrote: > > Structural editing, like paredit, is really the only sane way to do > Clojure code.

Re: which one would you prefer (instantiate vs. new-instance)?
Looks like the tradeoffs are composability vs avoiding reflection. I personally would go for the function until performance becomes a concern. Being able to use it in HOFs is a big deal!

Re: what should I use for my webapp?
I reckon you can have this going in a couple hundred lines of code. webnoir.org: http, routing, html generation. pick it up, tell it what you want. couldn't be simpler. sqlkorma.com: sql query dsl. clojuremongodb.info: mongodb query dsl. Probably the most sticky bit is the Google auth, but perhaps by now there is code available. github.com/cemerick/friend should get you started. or if you're feeling adventurous, you could grab Datomic Free and have some fun with it. We (a team of 3) are currently building a production stack with Datomic and Noir. I listed SQL and Mongo just in case :-) Feel free to ask me more here or off-list if you like!

Thanks for your contributions, Peter! Tower is of particular interest to me. Are you planning any support for ClojureScript with Tower, at all? Either way, I know we'll almost certainly make use of Tower. We will need to bring what Tower does into our cljs app as well. Perhaps we can contribute!

Re: Multiple ClojureScript (sub)projects with shared CLJS libraries per single clojure project
I'm planning a base app which loads and unloads cljs mini-apps into the
main app, one at a time. The problem domain is such that there are simply
too many mini-apps to load upfront.
Is lein-cljs build clever enough to generate exports and externs so that
these modules can talk to each other? For second prize, is it possible to
metadatum stuff and have lein-cljs generate an appropriate externs file?

ClojureScript and Google Closure Type Annotations
Forgive me if this has been asked before.
I am writing a GClosure app at the moment (using the long-form java-style
Google Closure javascript *blecch*), and I'm using JSDoc type-annotations
for everything:
/** @type {number} */
var x = parseInt( data['foo'], 10 );
These annotations allow ADVANCED_MODE Closure compilation to type-check and
also more tightly compress the resultant Javascript 'binary'.
Looking at the size of the ClojureScript One production 'binary', it's
187kb big.
I'm wondering if there's any plans or work underway to work on reducing
this size, both in terms of having the ClojureScript backend include JSDoc
style type annotations and in other ways?
Related question:
As I already have a large GClosure codebase, I would like to use CLJS to
build out the backend of this app, and bring the CLJS binary in as a module
for my app to use. I know I can export symbols in CLJS, and I'm guessing
it can't be that hard to generate an externs.js containing all those
exported symbols for use in my main app? If anyone is doing, this, please
let me know how!
