Using the basepath filter to re-write URLs in Webby?

Question

Basepath Filter Rewriting?

I'm trying to use the basepath filter in webby to rewrite all of the URLs in my project.

The documentation on the basepath filter for Webby is a little bit "light" concerning this, and there just simply isn't enough of it that I can understand how to use it.

If I find the solution to this, however I plan to contribute some documentation to the project.

I also understand that in order for this to work, I'm supposed to have all of my paths for the URLs it rewrites to start with "/".

I've tried applying the filter like so, to my default.txt template...

---
extension: html
filter:    erb
       basepath
---

** - Top of layouts/default.txt**

Then I run the command:

leeand00@someHost: webby rebuild BASE='http://www.yahoo.com/bob/'

** - Running the command from the root directory of the project**

but all I get is an error...

** Invoke rebuild (first_time)
** Invoke configure_basepath (first_time)
** Execute configure_basepath
** Execute rebuild
webby aborted!

Answer 1

Try changing your filters section so that it uses valid webby syntax. It should look like this:

---
extension: html
filter:
  - erb
  - basepath
---

Answer 2

I confirm that the answer is correct. I would like to explain why, it is because the meta-data of the pages is in yaml ( http://en.wikipedia.org/wiki/YAML#Lists )
