Breve 1.1.8
Cliff Wells
Here's a summary of changes I intend to have in place by then:
1) New documentation (almost done).
2) Tag multiplication or variation thereof (done but needs to be decided
whether to make it a method or an operator).
3) Tag.walk method (done but needs more testing).
4) Deprecate conditional tags (when, switch/case). (done).
5) UTF-8 conversion for all plain strings (almost done).
I think that about covers it. New features are being documented here
until the release:

Also, this method is a first step down the road to having full DOM
manipulation, so I'm curious if anyone is interested in such features
(i.e. the ability to create a load a Breve template, then traverse the
DOM, find elements and modify them, delete elements, create new ones,
etc, prior to flattening).
For example (untested, obviously):
from breve.flatten import flatten
from breve.tags.html import tags
globals( ).update ( tags )
logged_in = False
username = None
template = html [
body [
div ( id='login-form', style='display:none;' ),
div ( id='content' )
]
]
def fill_login ( tag, is_tag ):
if tag.attrs.get ( 'id', None ) == 'login-form':
if logged_in:
tag.children.append (
form ( action = '/login' ) [
'username', input ( type = 'text', name = 'username' ),
'password', input ( type = 'password', name = 'password' ),
input ( type = 'submit', value = 'submit' )
]
)
else:
tag.children.append (
span ( id = 'hello-user' ) [ 'Hello %s' % username ]
)
tag.attrs.style = "display: ''"
return False
template.walk ( fill_login, tags_only = True )
print flatten ( template )

Oops. Lots of errors. Well, now it's tested and works =)

<html>
<body>
<div style="display: ''" id="login-form">
<form action="/login">
username<input type="text" name="username"></input>
password<input type="password" name="password"></input>
<input type="submit" value="submit"></input>
</form>
</div>
<div id="content"></div>
</body>
</html>
I'm still unsure of how useful this would be in real life, but I assume
it would be useful to someone, and the cost to everyone else is nil.

This sounds very useful to me. As you stated, the cost to people who
don't want to use it is nil, and there is certainly potential for
people who do want this kind of stuff, so yes, please, let's have it!
