Hugo Canonical

A canonical URL is the URL of the best representative page from a group of duplicate pages, according to Google. For example, if you have two URLs for the same page (such as example.com?dress=1234 and example.com/dresses/1234), Google chooses one as canonical. Similarly, if you have multiple pages that are nearly identical, Google can group them together (for example, pages that differ only by the sorting or filtering of the contents, such as by price or item color) and choose one as canonical. Google can only index the canonical URL from a set of duplicate pages.

How to add a Table to Hugo

{{ $new := printf "<table class=\"%s\">" $class }} {{ $htmlTable :=
  replace $htmlTable $old $new }} {{ $htmlTable | safeHTML }}
</table>
EOF

Commento - Selfhosting Comment

Selfhosting Comment

some people mentioned that they can’t commment on some blogs. let’s change that, even there is not lot of feedback. i appreciate and read every comment and interaction with you, my readers.

poeple who knows me that i like todo most of the stuff self. so, i’d never buy a “service” for hosting some comments. i’ve got enough infrastructure running so i can host and operate it on my own.

Hugo - Start

GoHugo from Scratch

Take a fresh VM with OpenBSD ;) otherwise, you have to adapt appropriate …

install pkg

Login as User which is part of the “wheel group”. Doas should allow all Users of the Wheel Group to get root.

doas pkg_add hugo-- nginx--

adduser webmaster

create a user “webmaster” and prepare virtual directories

doas adduser webmaster
doas mkdir /var/www/virtual
doas chown webmaster /var/www/virtual/

Update Nginx

we need to modify nginx, prepare a site folder and a basic config for the webserver. do some stuff as root

Hugo Copy Button

I like Websites with the Copy Button for certain Snippets. Why not integrate into the own Blog ?

Folder, Copy JS Stuff

Change to Hugo Root Folder

mkdir -p static/js/

cat << 'EOF' > static/js/copy-code.js
(function() {
  'use strict';

  if(!document.queryCommandSupported('copy')) {
    return;
  }

  function flashCopyMessage(el, msg) {
    el.textContent = msg;
    setTimeout(function() {
      el.textContent = "Copy";
    }, 1000);
  }

  function selectText(node) {
    var selection = window.getSelection();
    var range = document.createRange();
    range.selectNodeContents(node);
    selection.removeAllRanges();
    selection.addRange(range);
    return selection;
  }

  function addCopyButton(containerEl) {
    var copyBtn = document.createElement("button");
    copyBtn.className = "highlight-copy-btn";
    copyBtn.textContent = "Copy";

    var codeEl = containerEl.firstElementChild;
    copyBtn.addEventListener('click', function() {
      try {
        var selection = selectText(codeEl);
        document.execCommand('copy');
        selection.removeAllRanges();

        flashCopyMessage(copyBtn, 'Copied!')
      } catch(e) {
        console && console.log(e);
        flashCopyMessage(copyBtn, 'Failed :\'(')
      }
    });

    containerEl.appendChild(copyBtn);
  }

  // Add copy button to code blocks
  var highlightBlocks = document.getElementsByClassName('highlight');
  Array.prototype.forEach.call(highlightBlocks, addCopyButton);
})();
EOF
