Is your feature request related to a problem? Please describe.
Not specifically.

Describe the solution you'd like
.NET 5 support, and the ability to reference Nuget packages from script files. I also think this is one way to handle themes (just package it up as a Nuget package).

Describe alternatives you've considered

Additional context

I'm mostly just creating this issue to track. I'll try and find some time to take a crack at some point.

Firstly, huge thanks for sharing your software in the public domain - incredibly generous.

Unfortunately I was unable to get this working on a Windows PC or a Mac. I suspect this may be due to it not being able to find the correct F# version, but I'm too new to coding to know whether this is actually the case.

Here are the errors I get with a 'build':

C:\Projects\FornaxTrial

   at Fornax.main$cont@57(String[] argv, ArgumentParser`1 parser, Unit unitVar)
   at Fornax.main(String[] argv)

The error is essentially the same for a 'watch'.

As I say, this may well be me misunderstanding where F# should be installed (in which case I apologise for recording this as an issue with Fornax!), however I can successfully run F# code on both computers and can use FSI successfully from the command line.

On the Windows PC, I have the following folders on this PC which suggest F# is installed:

C:\Program Files (x86)\Microsoft SDKs\F#\4.1
C:\Program Files (x86)\Microsoft SDKs\F#\10.1

Under both of these there is a 'Framework\v4.0' folder, the contents appear to be the same in each.

When starting FSI on the PC I get:

Microsoft (R) F# Interactive version 4.1

I have various dotnet framework version installed (including 4.6.2 and 4.7) and plenty of dotnet core versions - please let me know if you need any further info in this respect.

Should basically be the same as either

• FSAC: https://github.com/fsharp/FsAutoComplete/blob/main/.github/workflows/release.yml
  • manual trigger
    or
• KeepAChangelog : https://github.com/ionide/KeepAChangelog/blob/main/.github/workflows/publish.yml
  • automatic on tag

Describe the bug
Installing fornax as a local tool on a CI server and trying to build a site throws an error "Couldn't find or load config".

To Reproduce

1. Create a fornax site (e.g. using fornax new)
2. Add a dotnet-tools.json with instructions to install fornax locally
3. Add a config file for your chosen CI platform which runs dotnet tool restore and dotnet fornax build
4. Push your site to a git repo and build using the CI service of your choice (e.g. TravisCI, Netlify, Azure Pipelines, etc.)
5. Watch the build fail and observe the printed error Couldn't find or load config.

Expected behaviour
The site should build.

Build Output
Below is the output from TravisCI. The same problem occurs on Azure Pipelines as well as Netlify.

The command "dotnet fornax build" exited with 1.

Notice that the working directory contains a config.fsx.

Additional Thoughts
Fornax works as expected locally with the globally installed dotnet tool, as well as with the locally installed dotnet tool. It seems that on these CI servers, the directory which dotnet fornax build is being run from is not the same as the directory which is being passed into the build process (i.e. this path from Directory.GetCurrentDirectory()).

Is your feature request related to a problem? Please describe.
I am currently working on a fornax project to build gh-pages as docs for other repositories. The default gh-pages link is created somewhat like the following

https://{user_name}.github.io/{repo_name}/

After which the fornax structure is appended. This leads to the problem, that relative links, which work fine in dev (exmaple: /content/content.md) will not resolve to the correct page in gh-pages (/{repo_name}/content/content.md).

Describe the solution you'd like
Maybe give fornax watch not only an option to user an alternative port, but also to adjust the dev url.

Describe the bug
Hey i am currently working on a PR to fix #104 but i can't build fornax following the steps in the README.md:

Seems to be an issue with the build.fsx, but i have no idea how to adress this.

Pretty sure i encountered it already in other projects which i then upgraded to use a build.fsproj to circumvent this.

The instructions to create a sample website fail during the invocation of fornax watch. I tried fornax build as well, with the same result.

It took me awhile to actually find the right commands. I feel like they should be front and center. What do you think?

Is your feature request related to a problem? Please describe.
Hello I am writing a class library for my markdig extensions, markdown parsing and core generator components. Everything is in this project and i noticed some strange behavior I don't really understand.

The hot reload triggers and markdown parsing happens and everything gets added to SiteContents on the loader level, but when i check the number of values of that specific type i see, that everytime i trigger the hot reload it just adds the new version to the existing values. And because i use Seq.find to find the correct html for my generator it returns the first fitting value, which is the old and not updated one.

So my question is: How does this happen? Can i somehow avoid this behavior?

Describe the solution you'd like
It works exactly the same way it works without using a library.

Describe alternatives you've considered
I started using Seq.findBack to always return the newest addition, but this will lead to problems if i hot reload to often as the values will not get dumped this way.
I could also initiate a new SiteContext in my loader, some very superficial testing showed that this could work, but there might be issues i am not aware of.

• Generator

Describe the bug

The installed version of MSBuild.StructuredLogger is incompatible with .NET SDK version 5.0.300 (and probably later); package restore fails with the error message:

NotSupportedException: Unsupported log file format. Latest supported version is 9, the log file has version 13.

1. Update your SDK to 5.0.300 (or newer):

$ dotnet --list-sdks

Describe the bug
When the path of a folder containing a fornax site contains multiple dots (.), the watch command will not trigger recompilation via any generator triggers. I encountered this in a repository with a name like this: RepoName.github.io

To Reproduce
Steps to reproduce the behaviour:

• create a folder called reproFornax.github.io
• initialize fornax (run dotnet new tool-manifest, dotnet tool install fornax, dotnet fornax new)
• run dotnet fornax watch
• change some text in a post markdown

Expected behaviour
content is recompiled and refreshed in the client due to the watch command.

Actual behavior
No recompilation is triggered. This can be circumvented by removing one of the dots in the folder name.

Environment (please complete the following information):

• OS: Win 10 Version 10.0.19042 Build 19042
• Ionide version: 5.3.2
• VSCode version: VSCode Insiders February 2021 (version 1.54)
• dotnet SDK version: 5.0.103

Just reinstalled .NET SDKs on a new machine. When I try to install Fornax as a global tool. I get the following:

nathaniel@nelknet-linux:~$ Fornax
It was not possible to find any compatible framework version
The specified framework 'Microsoft.NETCore.App', version '2.2.0' was not found.
  - The following frameworks were found:
      3.0.1 at [/usr/share/dotnet/shared/Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The .NET Core frameworks can be found at:
  - https://aka.ms/dotnet-download
nathaniel@nelknet-linux:~$ dotnet tool list -g
Package Id      Version      Commands
-------------------------------------
fornax          0.2.0        Fornax  
nathaniel@nelknet-linux:~$ 

Two things:

1. It doesn't work
2. The command requires Fornax to be capitalized.

Is this something that can be fixed with a new release of the global tool?

The current global.json is locked at 5.0.102.

This release is critically flawed on some Linux hosts, where recent versions of nss or ca-certificates can cause package verification to fail during dotnet restore.

After the recommended upgrade to 5.0.202, the build workflow is broken:

$ dotnet tool restore
Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
  * You intended to execute a .NET program:
      The application 'tool' does not exist.
  * You intended to execute a .NET SDK command:
      A compatible installed .NET SDK for global.json version [5.0.102] from [/home/rob/dev/git/Fornax/global.json] was not found.
      Install the [5.0.102] .NET SDK or update [/home/rob/dev/git/Fornax/global.json] with an installed .NET SDK:
        3.1.407 [/usr/share/dotnet/sdk]
        5.0.202 [/usr/share/dotnet/sdk]

I can resolve this locally by editing global.json to choose the highest installed feature band:

Right now Fornax looks at the layout property in the md file to find the corresponding fsx file in the templates folder. I think that for consistency, we should either rename that property to template, or rename the templates directory to layouts.

Describe the bug

First off, sorry if this isn't the correct place for this. I have a strong feeling it's more PICNIC than an actual bug, but perhaps shedding a bit of light on this might be valuable for anyone in the same position. I also tried casting my hook into the Slack, but didn't get any bites.

I've restructured the basic example a little and was just toying with Fornax generally, but I'm finding that whatever I put in to my SiteContents within my loaders is not then available in my generators. I'm not sure if I'm missing something super basic, but I was hoping I could get a little bit of guidance. If it's something that perhaps needs clearing up in the docs for clueless people like me, I'm happy to help with that.

I've tried a number of dfferent types, and I've also been able to confirm that the record goes in to the DI container (as I can get it back out within the loader), but once I come to the generator stage, I can't seem to retrieve them. I know it's something obvious I'm missing...

I've created a dump of the repo I was working on here here.

To Reproduce
Steps to reproduce the behaviour:

1. Clone the example
2. fornax watch
3. Observe the exception that the Site record couldn't be pulled from the DI container, despite being added in the globalloader.fsx

Environment (please complete the following information):

• OS: macOS Mojave
• Ionide version:
• VSCode version: 1.50.0
• dotnet SDK version:
• mono / .Net Framework version: 5.0 RC1

It would be a must if the error were reported in red making it easier to spot.

When you have a block of text it is not always easy to sport / focus on the error section.

Moved from https://gitlab.com/Krzysztof-Cieslak/Fornax/issues/6

In order to deploy Fable.Powerpack doc site I needed to cheat on the links generated by Fornax.

// Toggle this lines when testing locally
// let host = "/"
let host = "http://fable.io/fable-powerpack/"

let defaultPage (siteModel : SiteModel) pageTitle (posts: Post list) content =
    let postsTabs =
        posts
        |> List.map (fun p ->
            li [ Id ("tab-" + p.title.ToLower()) ]
               [ a [ Href (host + (p.link.Substring(1))) ] [ !!p.title ] ]

     //...
)

I would like to make the generated links by Fornax relative and not absolute. I think the changes needed are located here

Hi,

I'd like to ask if Fornax has some functionality akin to Hugo's shortcode system (https://gohugo.io/content-management/shortcodes/)?

These are snippets placed inside Markdown to call a custom function that outputs HTML. This way you can add anything to your Markdown sections and e.g. turn a normal image into an adaptive image using srset and different image sizes.

Cheers,

Stefan

should I split this issue?

Describe the bug
Fornax can't support files with non url safe characters. If a mark down file in the posts directory contains a space in the file name, it will break the default template.

To Reproduce
Add a file named 'post with spaces.md' to the post directory
Test the template, it will fail to load.

Expected behaviour
The template should load

Environment (please complete the following information):

• OS: Windows 10
• Fornex version: build from latest master
• dotnet SDK version: 3.1.101

Additional context
The url encoding seems to come from this method:

    let relative toPath fromPath =
        let toUri = Uri(toPath)
        let fromUri = Uri(fromPath)
        toUri.MakeRelativeUri(fromUri).OriginalString

Building the site will fail with this error:

An unexpected error happend: System.IO.FileNotFoundException: Could not find file 'C:\code\Fornax\src\Fornax.Template\posts\post%20with%20spaces.md'.

We could fix this by calling System.Web.HttpUtility.UrlDecode, but that results in the following error:

   at Fornax.guardedGenerate@168(String cwd, Unit unitVar0) in C:\code\Fornax\src\Fornax\Fornax.fs:line 170

Again, we could fix this by calling System.Web.HttpUtility.UrlDecode, but means the generated Url for the page is incorrect because it has not been correctly url encoded. This is harder to do, as we need to encode the file and directory names but the directory separator characters.

Describe the bug

Right now when loading a generator/loader Fornax transform the name of the file using textInfo.ToTitleCase meaning that if the user write postLoader.fsx it will be transformed into Postloader for the open instruction.

From what I see, when using #load "postLoader.fsx" the name of the module generated by the F# compiler is PostLoader meaning that it only capitalise the name of the file.

Can we change

let internal getOpen (path : string) =
    let filename = Path.GetFileNameWithoutExtension path
    let textInfo = (CultureInfo("en-US", false)).TextInfo
    textInfo.ToTitleCase filename

to

let internal getOpen (path : string) =
    let filename = Path.GetFileNameWithoutExtension path
    let textInfo = (CultureInfo("en-US", false)).TextInfo
    string (textInfo.ToUpper filename[0]) + filename[1..]

// or this one as I am not sure if the CultureInfo is required
let internal getOpen (path : string) =
    let filename = Path.GetFileNameWithoutExtension path
    (string filename[0]).ToUpperInvariant() + filename[1..]

Doing this change would allow the user have better naming for its files.

This generator always add an error into the context.

let generate (ctx: SiteContents) (_projectRoot: string) (page: string) =

        let error =
            {
                Path = page
                Message = $"Post %s{page} not found in the context"
                Phase = Generating
            }

        ctx.AddError error

        Layout.generationErrorPage ctx

The only log we get back is:

BAD FILE: posts/first.md

I think it would make sense to also log the message so the user understand the reason of the error.

Is your feature request related to a problem? Please describe.
I would like to be able to extend fornax functionality with my owns scripts that are sort of meta generators, so I can do stuff like fornax newpost posts/hello and have the script make a the file filled with a basic front matter or fornax check to verify that configured generator and loader scripts actually have the appropriate functions without having Fornax build files halfway.

Describe the solution you'd like
Config is extended to have a ScriptConfig list (ScriptConfig contains a command and script filename) .

The actual script would need to have a function with signature run (projectRoot : string ) (config : Config) (args : string list ??) (result : Result<string, ScriptError> )

So say we have a ScriptConfig {command="newpost"; script="newpost.script"} and run fornax newpost posts/hello Fornax would evaluate the script (located in the scripts directory) passing along the appropriate arguments.

Describe alternatives you've considered
Running dotnet fsi check.fsx but using this would a be lot more work for the script to be aware of Fornax stuff.

Additional context
Got the idea while looking through #67 and thought that having Fornax as an extensible engine would be nice.

The port 8080 is used by a lot of other dev servers and this can lead to port conflicts.
It would be handy to have a port argument to manually specify the desired port for the dev server.

Knagis/CommonMark.NET#121
Maybe replace it with https://github.com/lunet-io/markdig ?

Background

I'd like to convert fornax to a dotnet cli tool because I think that the target audience would be happy to consume it this way (it also appears to be more practical to deploy it using the dotnet/nuget infrastructure). To do this there are a couple of steps I'd need to tackle:

• Update proj format (no dotnet standard and netcore with the old proj format 🙁)
• Use netstandard conform dependencies (FsYaml still forces full framework on the project)
• Update build tooling to leverage dotnet sdk (not strictly necessary but if we're already touching stuff it would be an obvious target)
• Switch to netcore (this would make sense in the mentioned scenario - it is debatable though)

Does this sound like a good idea - would you wish to see the project go in another direction?

WIP

I created a pull request which implements the needed changes to use the new project formats. I'd open other issues to address the other topics in a more focused manner. The PR is #7.

Describe the bug
Fornax is generating output for a generator with no generate function.

To Reproduce
Steps to reproduce the behaviour:

1. fornax new
2. Delete everything in contact.fsx
3. fornax build
4. See contact.html generated with content in it.

Expected behaviour
An error occurs, like say "Fornax couldn't detect a generator in this file" or something to that effect.

Environment (please complete the following information):

• OS: Windows 10 / Ubuntu 20.4
• Ionide version: 5.5.5
• VSCode version: 1.56.1
• dotnet SDK version: 5.0.203

Is your feature request related to a problem? Please describe.
In Hugo archetypes are templates for .md files that will be created in the posts directory. They make it easy not new post, for example helping to structure the url consistently.

Describe the solution you'd like
Command line something like:

fornax newpost "Some thing very interesting" 

template would be kept in "archetypes"

I would be will to implement this, but wanted discuss the solution before starting.

Describe the bug

Changing a Markdown file in watch mode makes the generators/post.fsx script throw an unhandled KeyNotFoundException.

The reason seems to be that an empty instance of SiteContents is being passed to the script.
Strangely, the first generation cycle runs to completion without a problem.

To Reproduce

1. Clone the source tree
2. Add a debug message showing the value of the SiteContents argument before Seq.find gets called in generators/post.fsx, e.g.:

let generate' (ctx : SiteContents) (page: string) =
    let allPosts =
        ctx.TryGetValues<Postloader.Post> ()
        |> Option.defaultValue Seq.empty

    eprintfn "%O has %d posts" ctx (Seq.length allPosts)

    let post =
        allPosts
        |> Seq.find (fun n -> n.file = page)

3. Build the demo project:

    dotnet tool restore
    dotnet fake build -t TestTemplate
   

4. The initial build finishes with output like this:

Starting target 'TestTemplate'

5. With watch mode running, edit a Markdown file, e.g.:

echo -e "\n\n### More\n" >> src/Fornax.Template/posts/post.md

6. Notice that the SiteContents argument now contains no post data, crashing the build:

Is your feature request related to a problem? Please describe.
I would like to host Fornax in an Azure Function and have it re-generate new content when requested, but I would want this to be fast and only generate the new content.

Describe the solution you'd like
Support incremental content generation.

Describe alternatives you've considered
Accept what exists or use Gatsby, which does support incremental builds.

Additional context
I assumed this might already exist for watch but didn’t see it listed.

Describe the bug
Changes to posts .md files are not reflected in _public/posts HTML files when running fornax watch. fornax build does update the HTML.

To Reproduce
Steps to reproduce the behaviour:

1. fornax new
2. fornax watch
3. Open post.md, change title to Cat, save file
4. Open post.html and see that the title is still Some nice post title

Expected behaviour
Title in post.html changes to Cat and is shown on page served by Suave.

It's could be interesting to add config file to Fornax. I propose to use Toml over yaml because I got a lot of exception when using FsYaml (still trying to understand the reasons). Also, Toml seems better for this kind of usage.

Example of config file:

Exclude = [
  "node_modules/",
  "packages/"
]

[Style]
type = "sass" # Could by less, css
entry = "main.sass"
output = "bundle.css"

Exclude

Array of path to ignore during Fornax build.

Why ?

Useful when people want to include CSS frameworks (via npm for example).

Current behavior

Read all the folders and build all the files fornax understand (less, sass, etc.)

Compatibility

If the option is not set, we keep the current behavior of Fornax.

Style

• Type: Type of the preprocessor to use
  • sass
  • less
  • css # Should probably not exist see "Compatibility" section
• Entry: Name of the entry file
• Output: Name of the output file

Why ?

In general, when using a preprocessor we have a bunch of files and only one entry point referencing the others. This setting allow this behavior and will improve the build time by fornax. Indeed, fornax will call the preprocessor only for the entry file and not all the files (who are useless).

Current behavior

Call the preprocessor depending on the file extension, and build each of the file found.
Take more time than needed, because it's process files that should be processed.

Compatibility

If the option is not set, we keep the current behavior of Fornax.

When people use css we could forgive to use this settings, as no processor is call. And let the current Fornax behavior.

The config file is optional, and if it does not exist then we keep the current behavior of fornax. Like so, we avoid breaking changes.

I can try to implement this features if you are ok with them.

Rationale

#3 states the need to generate RSS feeds for Fornax sites. I can think about also adding atom feeds, sitemaps and other files that basically have a custom format and need information from the site model as well as the available posts.

Maintaining all these different generators within the main project could induce a lot of friction. Having the possibility to ad-hoc generate files based on the specific site configuration (as well as needs of the site creator) seems to be a good idea.

Implementation

I built a working version with #34. It works the same way the HTML version of posts are generated only that it would execute at the end of the site generation process and produce a single file per generator.

I specified the folder in which generators live as _generators in the root directory. A custom generator only has to be called cenerate and be of the type CustomGenerator<'a> where 'a is the SiteModel.

The simplest possible custom generator could look like this

#load "../siteModel.fsx"

open SiteModel

let generate : CustomGenerator<SiteModel> =
    fun siteModel posts ->
        "Hello world", "/path/hello.txt"

The type CustomGenerator<'a> boils down to these types in the Fornax model

type FileContent = string
type VirtualFilePath = string
type CustomGeneratorResult = FileContent * VirtualFilePath

type CustomGenerator<'a> = 'a -> Post list -> CustomGeneratorResult

This would mean you only have to produce some string content (in any way you wish) and provide a path (like /feed/feed.xml) and you're good.

What do you all think about this? Would be glad to have your feedback on this to make this work 😊

Folowing log shows that there are errors, biut fornax ended with 0 code. Most CI servers will continue to deploy errored build and it can be bad

To Reproduce
Steps to reproduce the behaviour:

1. Clone the Fornax repo
2. Apply the change described in #82
3. Build the repo (dotnet tool restore, dotnet fake build, dotnet fake build -t Test)
4. Create a new fornax project (fornax new)
5. Attempt to build the project (fornax build)

Expected behaviour
Fornax builds the site.

Hello, i am trying to use lit web-components in fornax and one problem i have is, that i cannot use custom html tags in fornax.

So i would really like to have a custom option in this discriminate union type.

Describe the solution you'd like

type HtmlElement =
        private
        | Custom of tagName: string * props: HtmlProperties list * children: HtmlElement list

// ...
and helper level tag =
    match tag with
    | Custom (name, props, children) -> format name props children level

module Html =
        let custom (tagName:string) (props : HtmlProperties list) (children: HtmlElement list) = HtmlElement.Custom(tagName, props,children)

Describe alternatives you've considered
I could propably use some js to replace an placeholder element with my custom html tag element, but thats seems not like a clean solution to me.

Additional context
What i want my Html to look like in the end:

Is your feature request related to a problem? Please describe.
Currently only MultipleId Generators are to be able to specify their output path while other generators have no idea where Fornax will actually put their output because the mapper is defined outside their scope.

Describe the solution you'd like
Add a new GeneratorOutput : GeneratorSpecified (or replace Custom with it) that allows use of generators with signature SiteContents -> string -> string -> string * string . Similar logic to MultipleFiles but with just one file.

Describe alternatives you've considered
Using MultipleFiles but with only one element.

Additional context
This issue came about when I wanted to add a bit of localization and discovered that I couldn't just add a file like say posts/post.md with a front matter containing lang : en and then have the generator output a file en/posts/post.html.
Sure I could just define a Custom mapper to do that but that's just duplicating loader logic into the config.

Describe the bug

A post folder path that contains a space character (or non-ascii char) will cause an error of System.Collections.Generic.KeyNotFoundException

To Reproduce
Steps to reproduce the behaviour:

1. Run fornax new
2. create a markdown file with path of "posts/subdir/a sub folder with space/post3 with space and 你好.md" :

├─ posts/
│  └─ subdir/
│      └─ a sub folder with space/
|               └─ post3 with space and 你好.md

3. Run fornax watch. Now we get an error :

An unexpected error happend: System.IO.DirectoryNotFoundException: Could not find a part of the path 'F:\Playground\Fornax\posts\subdir\a%20sub%20folder%20with%20space\post3%20with%20space%20and%20%E4%BD%A0%E5%A5%BD.md'.

Environment (please complete the following information):

• OS: win10-x64, 10.0.19042
• Ionide version: v5.7.3
• VSCode version: 1.61.0
• dotnet SDK version: 5.0.102
• mono / .Net Framework version: -

Additional context

the relative function calculates the relative path by using the MakeRelativeUri method:

    let relative toPath fromPath =
        let toUri = Uri(toPath)
        let fromUri = Uri(fromPath)
        toUri.MakeRelativeUri(fromUri).OriginalString

However, when a directory path contains an space char, the result will not be decoded, and then causes an Exception of :

An unexpected error happend: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. System.Collections.Generic.KeyNotFoundException

Actually, this exception also occurs when having any directory that uses non-ascii encodings. For example, if we have a post with path of posts/subdir/中文 目录-带空格和非URL字符/post 带空格3.md, the relative funtion will return:

posts/subdir/%E4%B8%AD%E6%96%87%20%E7%9B%AE%E5%BD%95-%E5%B8%A6%E7%A9%BA%E6%A0%BC%E5%92%8C%E9%9D%9EURL%E5%AD%97%E7%AC%A6/post%20%E5%B8%A6%E7%A9%BA%E6%A0%BC3.md

And the above path will be passed to the generate function as a file path. However, the encoded url is not the original path.

A quick fix is to use the Path.GetRelativePath as below :

    let relative toPath fromPath =
        Path.GetRelativePath(toPath, fromPath).Replace("\\","/")

I've installed sass, but this message still provided and styles are not generated.

One thing that made Jekyll (and then Hugo) so popular was that you could just get a theme from a website, and there are lot of themes available: https://themes.gohugo.io/

I select a theme meant for a blog, I get out-of-the-box:

• Rss and sitemap generators
• Google analytics component
• Disqus component
• Sidebar menu component
• SEO-optimised site (e.g. meta-header-tags, social media share tags, etc.)

The reason people sharing these is, that the static site (/blog) is not core business (/subject of the main interest for the user). For example, Google Analytics script is same for everyone and if Google changes the script version, then who actually wants to maintain that by themselves...

What is the goal of Fornax, will it be an alternative for HUGO?
How does it help users to share these kind of higher-abstraction components like themes?

Describe the bug
Running dotnet fornax watch generated files as expected, but exited immediately after generation without further input.

To Reproduce
Steps to reproduce the behaviour:

1. Run the commands specified here: https://github.com/ionide/ionide.github.io/blob/dev/README.md
2. Wait for file generation to complete
3. The command exits

Expected behaviour
The watch command should still be running after generation for inspection of the generated site.

While #46 added functionality for loader errors (which is nice but undocumented) I don't see a way to report errors from the generators.

Currently if a generator operates over invalid page data it is not able to express this in a nice way. For example if a post.md file is missing title in the top matter this is the result:

An unexpected error happend: Exception has been thrown by the target of an invocation.
... more useless logging which tells you nothing

My first thought was to catch the invocation exception and indicate which page is failing during the generation phase.

That results in this:

The expression for /Users/joergbeekmann/Documents/Fornax/FornaxDemo/generators/post.fsx either couldn't be compiled or experianced a runtime
[11:34:23] '/Users/joergbeekmann/Documents/Fornax/FornaxDemo/_public/posts/post2.html' generation failed

Better, at least you know which page it is. But there is no way for the generator to indicate what is wrong with the markdown on the page. In this case a missing title.

I propose the load/generate phases be changed to collect editing level errors and surface them in the console. See PR #46 for a proof of concept.

It would be great to have a link to Install Sass page in ReadMe and not only in error logs (that is good).

It would be nice if instructions to build the project could be easily found in the README; I don't know if they're visible elsewhere.

Describe the bug
#r "nuget:Fornax" will download the package to the .nuget cache but the dll can't be found. This means in the F# 5.0 world it will not be possible to write loaders, etc with just nuget refs.

To Reproduce
Open the below as a .fsx file in Ionide on a system with .NET 5.0 installed. Note SiteContents is not not visible to compiler. Uncomment the direct reference and it becomes visible. I believe this is because the Fornax.Core.dll is in a non-standard location.

#r "nuget: Fornax"
//#r "/Users/joergbeekmann/.nuget/packages/fornax/0.13.1/tools/netcoreapp3.1/any/Fornax.Core.dll"

let x: SiteContents option = None

Expected behaviour
SiteContents should be resolved like it is if the direct reference is in place.
