Custom tags via AddMvc? about fluid

[sebastienros]

You can change the default template type which is FluidTemplate.

FluidTemplate.Factory.RegisterTag<QuoteTag>("quote");

I am adding it to the documentation

[sebastienros]

using Fluid.MvcViewEngine; and not using FluidViewTemplate

@sebastienros Thank you for the suggestion!

Would the above go in Startup.cs, or somewhere else?

I tried this:

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
        TemplateContext.GlobalMemberAccessStrategy.Register<Person>();
        TemplateContext.GlobalFilters.AddFilter("slug", SlugifyFilter.Slugify);
        FluidTemplate.Factory.RegisterTag<SvgTag>("svg");
    }
}

But I still see a syntax error in the view:

Exception: Syntax error, expected: if, endif, elsif, else, unless, endunless, case, endcase, when, for, endfor, continue, break, comment, endcomment, raw, endraw, cycle, assign, capture, endcapture, increment, decrement, include, layout, renderbody, section, endsection, rendersection at line:0, col:3

Try in the static constructor of the Startup class, to be sure it's run before anything.

[sebastienros]

If that still doesn't work I assume I will need to change the way we register the view engine to provide a custom template type, which will be one of yours like in the documentation.

Just tried this:

public class Startup
{
    static Startup()
    {
        FluidTemplate.Factory.RegisterTag<SvgTag>("svg");
    }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
        TemplateContext.GlobalMemberAccessStrategy.Register<Person>();
        TemplateContext.GlobalFilters.AddFilter("slug", SlugifyFilter.Slugify);
        // FluidTemplate.Factory.RegisterTag<SvgTag>("svg");
    }
}

Same result (no compilation errors, but same error in the view).

[sebastienros]

Got it working, you actually need to change FluidViewTemplate:

        static Startup()
        {
            FluidViewTemplate.Factory.RegisterTag<MyTag>("mytag");
        }

@sebastienros I feel like I still might be missing something. When I change FluidTemplate to FluidViewTemplate, I see compilation errors like this:

Startup.cs(7,7): error CS0246: The type or namespace name 'FluidViewTemplate' could not be found (are you missing a using directive or an assembly reference?)

Here is a larger look at my Startup.cs file, so you can see what directives I'm using as well:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using ClientName.Models;
using Fluid;
using FluidViewTemplate;
using FluidMvcViewEngine;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using ClientName.Liquid.Filters;
using ClientName.Liquid.Tags;

namespace ClientName
{
    public class Startup
    {
        static Startup()
        {
            FluidViewTemplate.Factory.RegisterTag<SvgTag>("svg");
        }

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
            TemplateContext.GlobalMemberAccessStrategy.Register<Person>();
            TemplateContext.GlobalFilters.AddFilter("slug", SlugifyFilter.Slugify);
            // FluidTemplate.Factory.RegisterTag<SvgTag>("svg");
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });


            services.AddMvc().AddFluid().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

Maybe you are missing a using statement. Look at the sample that does that in the repo.

[sebastienros]

Apparently you typed using statement by hand, hoping you'd be lucky ... you were not. Try to use Intellisense for that ;)

Ha, in this case I wasn't the one who created the Startup.cs! But you're right, using Fluid.MvcViewEngine appears to have been missed, and restoring it fixes the problem.

Thanks for your help!
