In my advanced compile, I see lots of lines that look like this:
return new qB(c,b,sB,new
s(null,5,[T,66,V,102,Qe,3,Re,34,Se,"/path/to/cljs/file/core.cljs"],null))};
My only guess is that it has something to do with source maps, but my
project.clj has zero mention of source maps anywhere.

Hi everybody!
I am trying to write an article about a topic I find interesting: embedded
templates.
Please, read and give me feedback, if you find the topic interesting. English
is not my first language, and I would appreciate all help to make it clearer.
Does it make sense? Or should I try
Can you look at the pre-optimized js sources and grep for that string? It might
be a macro of a library. Hard to tell without knowing what that thing actually
is. It looks like something var-ish (ie. :line, :column, :file, ...).
Anyways look at the js files to see the full context, should make
ClojureScript is aimed at users who are already using jQuery and other
helper libraries like Underscore.js. These two alone put your JS
application around ~40K gzipped without having written a line of code
yourself.
ClojureScript applications start at around ~20K gzipped and go up from
there.

Try the :pseudo-names compiler option to see what the :advanced code is
referring to
(https://github.com/clojure/clojurescript/wiki/Compiler-Options#pseudo-names).

Hi John,
Thank you for sharing your work in progress.
Tomorrow I'll dedicate a couple hours to go over this, and I'll review it
as a brand new user of CLJS/Reagent/React, and at least give you feedback
about clarity.
I don't think we'll be using JSX but I'm very open minded to see what

Hi Marc!
Don't expect it to be a good introduction to Reagent.
By the way, I think your choice is a wise one. Reagent is really nice to
work with.

Looks like metadata leakage. Need a minimal example though.

I can try to produce an example if I know where to start. There is
nowhere in my app that I am specifying a path to a file, so I'm not
sure where this is happening.

The problem is metadata leakage. This has nothing to do with specifying
paths in your code. Somewhere you are writing map literals (perhaps in a
macro?) and compiler metadata is leaking.

Ok, can you clarify the type of map literal that would do this? I have
not written any of my own macros on this app, but perhaps a library I
depend on has them. By map literal, do you just mean a {:foo :bar}
type of syntax, or something else? I also have not added any metadata
myself to anything in
Yes {:foo :bar}

Ok, I'm sorry if I'm missing the train of thought on this, but how
does any ordinary clojure(script) map lead to what you call metadata
leakage that contains paths to files? Of course I use maps all over
the place (doesn't everyone?), but I don't see how this connects to
the problem I'm having.

You have as much of an idea why this happening as I do.
Which is zero :)
Without a minimal reproducer there is nothing for anyone to do.
You need to sort yourself what line of your ClojureScript or your
ClojureScript dependencies is generating these maps.
Then maybe someone can offer a solution
Andrew, the metadata you are seeing is added by the CLJS compiler to the
Clojure objects it creates as it is reading CLJS code. You did not add it
explicitly in your code anywhere, and we're not saying you did.
The problem here is that the metadata did not *stay* in Clojure but got emitted
into

Thanks, this helps, I'll try to track it down. I've made some slight
progress in that a closer inspection of the grep results shows that
the only JS files where these paths are showing up are files in which
I define Om components, all my other JS files unrelated to Om do not
show these paths. I'll
Ok, I managed to create an easy reproduction of this. The problem goes
away when I roll back my version of clojurescript.
I have a simple lein template I use for various things. Its
dependencies are listed here:

FYI, Kioo works with Reagent as well.

Just a quick follow up: I wrote a small Node script to analyse the contribution
of each source file that goes into the final artifact. It works by reading the
source map and simply counts each character, attributing it to the original
source file.
Here is a sample output:

Some semantic confusion on my part. Sorry.
I use the word "template" to refer strictly to out-of-language templates
like HTML markup prototypes that can be cloned, augmented and populated
based on data, or the old string substitution and innerHTML type templates.
I have not yet started referring t
I'm trying to figure out how to best deal with an issue on the newer versions
of the class compiler:
https://github.com/purnam/purnam/issues/8
I've reproduced the issue causing the warning in this particular piece of code
(ns compiler.issue-1
(:require [purnam.test])
(:use-macros [purnam.co
Seems to be related to reify. I updated the issue with minimal repro
example:
(defprotocol Foo (foo [_]))
(defn new-foo []
(reify Foo (foo [_])))
(new-foo)
