Edit block templates inside the manager with Scriban

2021-08-12 Piranha
Want to edit block templates without rebuilding your project? Let Scriban help you with that. Scriban parses your custom Html and objects and then gives you HTML ready to be used anywhere.

Scriban makes your life easier as a developer when you need to merge texts with data from your objects. By simply adding double curly brackets followed by your objects properties you can specify where in the text your data will be inserted. This comes in handy when generating emails, PDF files and much more.

Also note that Scriban automatically converts your property names into lowercase characters and if you have multiple capital letters they will be separated by underscores. This is due to the fact that Scriban is based on "Liquid templates". In other words the property MyPropertyIsNice will be converted into my_property_is_nice

There is a section in Scribans documentation that covers this issue with a possible solution. You can read more about the issue here:  https://github.com/scriban/scriban/blob/master/doc/runtime.md#member-renamer

This block's HTML is powered by Scriban

By passing a string with your custom html and block object, Scriban can merge these two and return finished Html. This makes it easier when you need a chance to tweak things within the same type of blocks

Install Scriban
//Visual studio
Install-Package Scriban

//Command line

    [Field(Title = "Title")]
    public StringField Title { get; set; }

    [Field(Title = "Content")]
    public HtmlField Content { get; set; }

    public string Html { get; set; }

    public void Init()
            var template = Template.Parse(HtmlTemplate.Value);
