Textile with ERB

B

Bill Atkins

I'm trying to use Textile and ERB together for a website I'm
developing. Basically, a sample file looks like:

---

<%= produce_some_output "param" %>

Here's some *Textile* text.


---

I want the ERB code to be evaluated and I also want the Textile markup
translated into HTML. How can I do this? Right now I'm doing:

s = File.read "myfile.rhtml"
result = RedCloth.new(ERB.new(s).result).to_html

The problem is that the produce_some_output function prints out the
opening <html>, <body>, and <head> tags. RedCloth surrounds this with
<p> tags and thus prevents the page from rendering properly. I tried
running ERB after RedCloth, but RedCloth converted the quotes in the
ERB code to HTML entities.

How can I make this work?

This is really the problem, right? Who wrote the produce_some_output
method? There doesn't appear to be an inherent problem with
comingling erb and RedCloth. You would have the same problem if you
replaced the call to produce_some_output with embedded <html>, <body>,
and <head> tags. Maybe I'm misunderstanding.

If you can't change the produce_some_output method to have it stop
returning the unwanted HTML tags, then you could hack the HTML tags
out with gsub, or (more accurate--more of a pain) use something like
the ruby htmltools library to properly parse the output and return
only the sub-nodes you want. Yuck. :)

Gosh. The problem was indeed in the produce_some_output method. :) Thanks.

I need to start thinking about problems more thoroughly before posting
them here.

I spoke too soon. I'm still having the problem. Even if i replace
the method call with <%= "<html>\n\ntext" %> it gets wrapped in <p>'s.
I was trying to avoid the gsub solution, but that's looking like my
best bet right now. Hmm.

OK, my solution (for anyone who's interested) was to put all textile
code between <textile>...</textile> blocks and then just transform the
text between the <textile> delimiters.

Oh, not to worry. I've long ago discovered that the fastest way to find
a simple bug is to hit the 'send' button.
