2.3.0

Page navigation bar made customizable. To take advantage of this feature in existing projects following files need to be updated:

Build.ps1: A -NavTemplate parameter needs to be added to the invokation of ConvertTo-NavigationItem. A -NavTemplate and a -HeadingLevels parameter needs to be added to the invokation ofConvertTo-PageHeadingNavigation. For example:

# Set-up the content mapping rules for replacing the templace placeholders
$SCRIPT:contentMap = @{
      # Add additional mappings here...
      '{{footer}}' =  $config.Footer # Footer text from configuration
      '{{nav}}'    = {
  	    param($fragment) # the html fragment created from a markdown file
  	    $navcfg = $config.navigation_bar # navigation bar configuration
  	    # Create the navigation items configured in 'Build.json'
  	    $config.site_navigation | ConvertTo-NavigationItem -RelativePath $fragment.RelativePath `
  	                                                        -NavTemplate $navcfg.templates
  	    # Create navigation items to headings on the local page.
  	    # This requires the `autoidentifiers` extension to be enabled.
  	    ConvertTo-PageHeadingNavigation $fragment.HTMLFragment -NavTemplate $navcfg.templates `
  	                                                            -HeadingLevels $navcfg.capture_page_headings
      }
}

Build.json: a navigation bar configuration section needs to be added:

...
"navigation_bar": {
    "capture_page_headings": "123456",
    "templates": {
        "navitem": "<button class='navitem'><a href='{{navurl}}'>{{navtext}}</a></button>",
        "navlabel": "<div class='navitem'>{{navtext}}</div>",
        "navseparator": "<hr class='navitem'/>",
        "navheading": "<span class='navitem{{level}}'>{{navtext}}</span>"
    }
},
...

2.0.0

The version of Markdig included in this release introduces an incompatiblity with projects which use the mathematics extension and were created with versions of this module older than 2.0.0 (i.e. 1.* or 0.*).

To address this incompaibility the KaTex configuration in all deployed html templates (md_template.html) need to be updated like so:

<script>
    // <![CDATA[
    window.onload = function() {
        var tex = document.getElementsByClassName("math");
        Array.prototype.forEach.call(tex, function(el) {
            katex.render(el.textContent, el, {
                                                displayMode: (el.nodeName == "DIV"),
                                                macros: {
                                                            "\\(": "",
                                                            "\\)": "",
                                                            "\\[": "",
                                                            "\\]": ""
                                                        }
                                            })
        });
    };
    // ]]>
