multiply yatl.helpers

[Lucas]

hello one and all,

I used to be able to TD('...')*3 within TR() and it would create 3 new instances of TD and insert it into the TR(), for instance.  it was a very elegant way of writing the code.  now I have to *[TD('...') for x in range(3)] to achieve the same result.  can we put that original TD('...')*3 functionality back into the yatl.helpers?

and is it possible to add BR = TAG['br/'] or so into yatl.helpers also?  I use BR constantly.

thank you in advance.  lucas

You almost can, you just need an extra set of []:

>>> str(TR(*[TD()]*3))
'<tr><td></td><td></td><td></td></tr>'

Is this acceptable?

I would prefer not to add more helpers to yatl to avoid a proliferation. Specifically the use of BR is not something I want to encourage since it is better handled with DIV display property and border-bottom.

As you can you can define [[ BR = TAG['br/']  ]] in your layout and it will be available everywhere.

yes, that multiplying by the list syntax is ok.  

and I have the [[BR=TAG['br/'] ]] in my layout.html and common.py because it is just easier than playing with css every minute of the day.  

there is so much rewriting from web2py that is practically like learning a new language.  I know it is faster because it is stripped down, but a lot is different.  sorry for complaining, I just have about 14 years of solid web2py code that is really quite good and functional.

Well. The templates and the dal are the same. That's all I can promise.

But definitively interested in ideas about how to make it better. Perhaps we need a more sophisticated scaffolding app.
