Can someone explain the new Markaby syntax to me? I'm using Markaby
as a Rails plugin, fetched from the trunk.
I'm losing my instance variables somehow ( <at> thing is always nil):
class ThingsController < ApplicationController
def index
<at> thing = "Bacon of the chunky variety"
end
end
# app/views/index.mab
h1 { "You should see a thing here:" }
p { <at> thing }
And I get a NoMethodError when trying to get at it with the thing()
method, as mentioned in the README.
I can, however, get to the instance variable like this:
<at> thing = <at> helpers.controller.assigns['thing']
What am I doing wrong?
Geoff
Yeah, this is my fault - sorry for the breakage :)
p { thing } should work just fine now (as of r91).
The idea behind these recent changes is to keep instance variables for Markaby's
own purposes, and force everything else coming in from outside (i.e.
controllers)
to go through method_missing. The code is a bit cleaner as a result.
Any objections to the new style?

Here's my first live Camping app, on the undergroun.d! http://peep.d I often need to come up with a color scheme that is made from an existing color. This little app takes a hex color and shows all the combinations of those colors. An observation and a question: At first it was including dispatch.fcgi into generated urls (http:// peep.d/dispatch.fcgi/colors). I renamed it to dispatch.rb and that helped. However, Camping still adds extra copies of the mount point: http://peep.d/colors/colors/colors/33/55/ff It works, but looks a little odd. I'm using lighttpd with the config from http:// code.whytheluckystiff.net/camping/wiki/TheCampingServerForLighttpd. I only have one route: class Index < R '/', '/colors/(\w\w)/(\w\w)/(\w\w)' The offending link is generated with a splatted array of three strings: R(Index, *color) Does anyone have ideas about what I'm doing wrong? Geoff
Hi Geoff, really nice idea, it will help me too. To answer your question : Look in the <at> root instance variable. It is the path to your application's root. We already had some problems with FastCgi -- -- Cheers, zimbatm http://zimbatm.oree.ch

Do you have any ideas how to approach it? Looking at
Rails' code:
# Called by CacheHelper#cache
def cache_erb_fragment(block, name = {}, options
= nil)
unless perform_caching then block.call; return
end
buffer = eval("_erbout", block.binding)
if cache = read_fragment(name, options)
buffer.concat(cache)
else
pos = buffer.length
block.call
write_fragment(name, buffer[pos..-1],
options)
end
end
It seems like Markaby might have to have a "length"
attribute and/or act like "buffer"? Or would Rails
need to be changed on the eval line?

Hello, I just joined the camping list. I was trolling the archives when I saw this: -- The biggest problem in Camping is authentication. This is a problem I propose to solve by providing an extension. That little bit of code uses the path to allow/disallow urls. That way it is unobstrusive. In the future I would also like to make an OpenID client and server for Camping. -- I was wondering if anyone had gone down the OpenID client/server route? I'm in the process of writing one myself as a demonstration of camping for my local ruby group. I'm in the process of writing the server, and I think I can supply the client as a mixin. If anyone has done work on this front, I'd be interested to combine efforts. I too see many opportunities for tiny little gnat sized apps working together in glorious harmony. And user auth is certainly the first step. Cheers, -Mark
Hi, I just put together a little mixin to provide pseudo-RESTful services in camping apps. Basically, it looks for a hidden _verb field in form posts, and sets the <at> method to the supplied value (e.g. put or delete - which browsers don't support). This lets you define put and delete methods in your controllers. Groovy. Code: http://pastie.caboo.se/22613 Is there any permanent repo of little code snippets/mini-libraries for Camping? Is the wiki the best place? I think a lot of camping code could be re-used via mixins and it would be nice to have a Camping-forge type place to go find existing work. Cheers, -Mark
hey, that's nice perhaps you could write up a page on the wiki ? http://code.whytheluckystiff.net/camping/wiki/LikeRails On 11/14/06, Mark Fredrickson <mark.m.fredrickson@...> wrote: > Hi, > > I just put together a little mixin to provide pseudo-RESTful services > in camping apps.
