New Post: TemplateManager.Render(...)

jgauffin — Fri, 28 Nov 2008 20:24:16 GMT

The easiest way is to inherit HttpServer and override the ErrorPage method.

I'll create an event for this later.

Hi Simon,
The TemplateManager doesn't actually read the files from the paths you specify directly but uses the path you insert and retrieves the files from each added ITemplateLoader (of which we've implemented two, the FileTemplateLoader and the ResourceTemplateLoader).
These loaders must be manually added to the TemplateManager upon creation:

new TemplateManager(new FileTemplateLoader(), new ResourceTemplateLoader)

Next up is to bind the resources you want available for rendering to the ResourceTemplateLoader (this have to be done manually since you might have resources you dont want available and moreover resources in strange namespaces supposed to be bound to other addresses). The binding is done to an url (since this is a webserver) and looks like this:

Assembly theAssemblyTheResourcesAreIn = Assembly.GetExecutingAssembly();
myResourceTemplateLoader.LoadTemplates("/toMyUrl/", theAssemblyTheResourcesAreIn, "The.Namespace.The.Resources.Are.in")

This will load all the resources in the specified namespace to the path "toMyUrl\\" and any resource in a child namespace to "toMyUrl\\subNamespace\\".

It might seem odd that we add the resources to url's and then you have to retrieve them using paths but we've made it as such since this will in most cases be used together with the ie ViewController in which case it is a bit more logical in the application to add resources to urls instead of paths (since the controllers work with urls).

Finally your example should then look like such:

ResourceTemplateLoader resources = new ResourceTemplateLoader();
resources.LoadTemplates("/views/logon/", Assembly.GetExecutingAssembly(), "YourProject.Views.Logon");
resources.LoadTemplates("/views/layouts/", Assembly.GetExecutingAssembly(), "YourProject.Views.Layouts");
TemplateManager manager = new TemplateManager(resources);

TemplateArguments arguments = new TemplateArguments(arguments);
string page = manager.Render("Views\\Logon\\Main.x", arguments);
arguments.Clear();
arguments.Add("text", pageTemplate);
return manager.Render("Views\\Layouts\\Application.x", arguments);

If you are using some kind of special format, don't forget to add a generator for it (since our default generator for haml wouldn't render any file ending with an .x).

Hope this cleared things up a bit for you, feel free to come again with any further questions.

Hi,

First of all, thanks a lot for that project. I think that can be really usefull and it look good!

I got a question about the Render method of the TemplateManager : it take 2 arguments, filename and arguments. How i can specifie the filename if the resource is embedded resource ?

There is the sample you put in the Tutorial5, it always crash on the second line and raize a FileNotFoundException :

TemplateArguments arguments = new TemplateArguments(args);
string pageTemplate = m_TemplateMng.Render("Views\\Logon\\Main.x", arguments);
arguments.Clear();
arguments.Add("text", pageTemplate);
return m_TemplateMng.Render("Views\\Layouts\\Application.x", arguments);

Thanks a lot !

Simon

Almund — Thu, 27 Nov 2008 12:14:34 GMT

Changed so that the IHttpClientContext.Respond takes an extra contentType parameter allowing HttpServer to send errors in text/plain (so that any code in the response doesn't screw up the html)

Updated the HttpServer so that the user can add custom redirect rules (previously without apparent reason the Add was restricted to RedirectRule, now it takes an IRule)

I havent found a limit anywhere in the RFC. If you do find one, please let me know.

Yes you can. I'll increase it to 4096 in the trunk tomorrow (monday).

It's just a protection against invalid headers.

New Post: .Net Framework versions

TheOtherMarcus — Mon, 03 Nov 2008 14:41:36 GMT

When I build with 2005 and have .Net Framework 3.5 installed, a file System.Core.dll is generated together with the output. As long as this file is distributed with the application, it works. The file is not needed if 3.5 is installed on the target machine.

If I build with 2005 and have only .Net Framework 2.0 installed, no System.Core.dll is generated.

When I run the application on a computer without System.Core.dll or .Net Framework 3.5, the web server generates no output on requests, but it seems to work in all other aspects.

I have no time to investigate the cause of this behavior at the moment.

New Post: .Net Framework versions

jgauffin — Wed, 29 Oct 2008 09:03:49 GMT

Then it should be compiled with 2.0. I'm no expert on the net framework (and having different versions installed).
We have both 2.0 and 3.5 on our developer machines (and both vstudio 2005 and 2008). On our production server we have only 2.0 installed, and it works fine.

Do you have any logs to see excactly where it stops?

I build in 2005. Which Framework version is used then?

New Post: .Net Framework versions

jgauffin — Wed, 29 Oct 2008 07:05:58 GMT

As far as I know, there is no way in Visual Studio 2005 to select .Net 3.5 as target platform. And we still develop the webserver in Vstudio 2005.

Do you compile the webserver in 2005 or 2008? If in 2008, check "Target framework" under "Application" properties.

New Post: .Net Framework versions

TheOtherMarcus — Tue, 28 Oct 2008 20:32:40 GMT

My web server does not return any data when I run it with .Net Framework v2. It works fine with .Net Framework v3.5. Is this a known issue?

Can someone explain to me how I know which version of the Framework is used when building and running applications when multiple versions of the Framework is installed. Does it matter that I build with Visual Studio 2005 on a machine with v1.1, v2, v3 and v3.5 installed, and then try to run it on a machine with v1.1 and v2 installed? I get no warnings or errors.

Renamed the input parameters to TemplateManager.RenderPartial to something a bit more understandable. Fixed so that the PartialNode passes the arguments to RenderPartial in the right order (making new arguments override old as should be).

Commented Issue: request.Uri not always correct

TheOtherMarcus — Fri, 24 Oct 2008 07:30:52 GMT

A request for uri "http://localhost:11111/123" will set request.Uri to "http://localhost/", which seems to be wrong.

A request for uri "http://localhost:11111/test/123" will set request.Uri to "http://localhost:11111/test/123", which I think is correct.

About keeping the server running:
I now wait on a semaphore in Main().

using System.Threading;

private static Semaphore terminate;

terminate = new Semaphore(0, 1);
Program p = new Program(port);
terminate.WaitOne();

In Program, I can do the following to exit the application:

terminate.Release(1);
