Nothing to do with source maps, behavior of console.log which we can do
nothing about. So yes, expected.

No idea, but I'm sure many other compile to JS languages are bugging them
about it :)

clojurescript source maps: chrome's expected behavior, firefox support

2014-02-17 Thread Ransom Williams 
First of all thanks to everyone working on clojure for making web 
development suck less.  I recently sandboxed a clojure server application, 
and the tooling, documentation, and availability of libraries are all 
awesome.

Anyway, I'm starting in with a clojurescript client now and want to confirm 
one detail about The Essence of 
Clojurescriptblog
 post:  Chrome (32)'s console indeed links the log message to a line in 
clojurescript, but the line number is in the enable-console-print! function 
in cljs/core rather than the call to println in hello_world/core.  Is this 
the expected behavior?  I guess I ought to read up on the details of source 
maps.

And finally, what about firefox?  The firefox (27) developer tools have 
source map support, and the debugger pulls up hello_word/core, but unlike 
chrome, it doesn't hit breakpoints, and the log message links to a 
javascript file rather than a clojurescript file.  Any word from mozillians 
on if/when-type questions?

So yeah, mainly just stopping by to say hey and thanks and to be another 
voice out there extolling the virtues of this practical lisp.

It seems likely (already done?) for browsers to support the X-SourceMap 
header and //@ comments for the target use case of CoffeeScript -> 
Javascript -> Minified Javascript

Also, it seems preferable to let the browser do it, so their debugger can 
operate at various levels of source translation depending on your needs.

So why bother doing it ourselves? For the Rhino environment?

Yep. This would require enhancing the Clojure reader. I don't think that's
feasible for 1.4, but probably worth pursuing for 1.5. Even without it, we
can still get line level debugging which is better than nothing and write
the code to use :column data when available.

Yes. Again this is really just bonus points. Priority 1 is just improving
the development experience.

 We could also decide to handle multi-mapping ourselves - that is write the
code that can produce a merged source map.

That's definitely the first step! After that, there's going to need to be 
some way to serve those source maps via HTTP upon request from the browser.

However, there's a first step to the first step: Getting column data. The 
reader currently seems to only produce a :line key in the metadata map.

Could you please clarify? Do you mean for multi-level mapping?

See the "Multi-level Mapping Notes" section in the v3 spec:
https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit?hl=en_US&pli=1&pli=1

It seems like once they agree upon a header (as opposed to the javascript 
comment syntax) this would also be useful for providing pre-macro-expansion 
vs post-macro-expansion source maps.

Re: ClojureScript source maps

2012-03-22 Thread David Nolen 
There are no existing attempts. The first step would be just to get the
compiler to emit an optional source map. Bonus points if we can merge
source maps from the ClojureScript compiler and Closure advanced
compilation.

Re: ClojureScript source maps

SourceMap support is rapidly approaching general availability in Chrome and 
Firefox:

http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/

I'd love to see this happen and *may* be able to find time to help with 
implementation.

Any intel on existing attempts at this?
