Monorail and Brail: how to access siteRoot in a common script?

[Gabriel Schenker]

I try to write a common script in brail and want to access the
siteRoot parameter.
But the compiler tells me, that it is not found...

my definition of the script is

def statusImage(status, title):
return "<img src='${siteRoot}/images/status_${status}.png' alt='$
{title}' title='${title}' />"
end

the exception is:

Exception Details: Castle.MonoRail.Framework.MonoRailException:
CommonScripts\statusImage.brail(1,1): BCE0005:
Boo.Lang.Compiler.CompilerError: Unknown identifier: 'siteRoot'.

You can't, unfortunately.
Common Scripts are just plain boo files, no brail magic.
You can access that from the HttpContext, I assume.

[Gabriel Schenker]

ok, I try this one (copied from Castle C# code...)

import System.Web
 
def applicationPath():
  path = HttpContext.Current.Request.ApplicationPath
  if "/".Equals(path):
    path = string.Empty;
  end
  return path
end

// some more code here...

but I get the following error now:


Exception Details: Castle.MonoRail.Framework.MonoRailException: CommonScripts\statusImage.brail(1,1): BCE0005: Boo.Lang.Compiler.CompilerError: Unknown identifier: 'HttpContext'.

interestingly I have no problems with other namespaces and/or classes of the .NET framework, e.g. System.Threading.Thread

what am I missing?

[Ayende Rahien]

import System.Web from System.Web

[Gabriel Schenker]

that was quick! thanks. It works now.
But just a question: when do I have to add the "from" to the import statement and when not
Is e.g. the mscorlib.dll automatically recognized and all others not?

[Ken Egozi]

I believe it's a matter of references.

by default the boo compiler references mscorlib for every compilation, while System.Web.dll is optional.
Same as in csc and vbc

that makes sense.

[Ayende Rahien]

More than that, if the namespace cannot be found the boo compiler will look for an assembly with the same name.

So:

import foo.bar.baz

Will look for assemblies named:

foo.bar.baz

foo.bar

foo

Before giving up.

The problem is that mscorlib already contains System.Web

[Ken Egozi]

what about:
booc.exe input.boo /eagerimport

eagerimport => always try to load references (from the current directory) even if the namespace already exists

[Ayende Rahien]

Um,

You are aware that I am not actually a member of the Boo, I am just a lowly user.

[Ken Egozi]

I know.
I also know an actual proposal should be pointed to the boo community, not to Castle.
