i’m doing some meta stuff and trying to figure out how to stick some  
erb html into a proc where i can then feed it to one of many helpers.

if i do something like this:

lamb = lambda do |x|  
 **\<%= x %\>**   
end

i get a syntax error because obviously the block isn’t actual code… i  
want to be able to do something like \<%= html\_helper(“something”,  
&lamb) %\>

any ideas?

thanks!

Stuart

because you’re in a ruby file, not an erb file you don’t need to be  
this complicated:

lamb = lambda do |x|  
" **#{ x }**"  
end

It’s a bit more fiddly if you want to call helpers - (one technique is  
to have a magic helper object which includes the various rails helpers  
so that you can then do magic\_helper.number\_to\_currency … and things  
like that)

nevermind… i’m an idiot… it works you just have to end the %\>  
before the erb block… duh
