problem:

• test/html_macros_test.exs:7: warning: you are piping into a function call without parentheses, which may be ambiguous.

solution:

• wrap params to Enum.each in parentheses

Cool! thx, I discovered yet another few in lib/html.ex

Fixes just went to 0.6.1 in Hex.

Cool! Thx for the library! Discovering some nice patterns in your code....

One question though: is there any possibility for pretty printing the html output? (I did not find any...)

[wkhere]

Pretty-printing - no.
The only thing remotely similar to nice output is that tag closings are generated with \n at start, which at least doesn't make the whole html one kilometer-long line. But it of course doesn't provide proper indentations.

One more thing, I don't want to scare you out of this project :], but it contains a subtle bug at the conceptual level and it is visible when you would start to nest your html-building constructs in different functions (or macros). Without going further, it's fine to say that the usage of this project is fine as long as you use don't call builders one from another.

Having said that, it's nice to hear somebody uses it, or plays with with for whatever purposes, even if educational.

Ah, I see.
Thanks for the hint considering the subtle bug.

Would it be good to document that "behaviour" with a test and if it is not fix-able, maybe put it in a "Gotchas" section in the readme? That way you're keep it very transparent for your users and maybe somebody decides to give it a shot fixing it.

Thoughts?
