Announcing org-webring

available as: html | org | pdf | tex | txt

Special appreciation to all contributors: Jamie Beardslee, Amin Bandali, Ivan Sokolov, and Alexandru-Sergiu Marton. Thank you to all those who gave review of the Emacs Lisp used in the project, and Drew DeVault whose openring1 served as a useful template.


Org-webring is an alternative implementation of a feed-based webring, taking inspiration from openring by Drew DeVault. Intended to integrate with Org-based websites and blogs (either directly, or indirectly, as in ox-hugo), it will fetch a given list of web feed files and correctly parse and format the elements to be displayed for sharing.

1 Introduction

There are certain elements from the “old web” that I feel many of us long for, and miss dearly. Personally, it seems as the internet ages we become more disparate and disconnected from each other. Consistently, we are faced with the reality that while the internet has provided us absolutely remarkable advancements, it has also plagued us with isolation.

One element from the web as a whole which I find most fascinating is blogging. Blogs are some of the most adventurous and accessible modes of detailing thoughts and expressions. I love them! A blog can be fictional, personal, political, technical, or whatever you want it to be. With the abundance of different ways to create a blog, it is easier than ever to get started. While I tend to read mostly technical blogs, especially in content areas I am most interested, the plethora of different mediums engaged in blogging are endless.

Blogging, while also a mode of expression, is also a mode of sharing with others. Something that I find particularly rewarding is discovering a particular blog, or blogpost that details something very exciting. I find sharing these entries rather exciting as well, especially to like-minded friends and colleagues.

A blog by Drew DeVault2 had an especially interesting feature, he was sharing recent posts from blogs he was following! Using a piece of software he had written, called openring, he had taken the old and often forgotten concept of a webring and made sharing a generated list of blog entries accessible to his audience!

There are many things that I feel openring does well, and while I have never used it there are friends of mine who have. They have positive things to say about the software and its apparent simplicity. While I am not a fan of the implementation language chosen for the project, I will easily concede that Drew has created something genuine for both himself, and his audience to use.

2 An Org implementation

While Drew’s openring is quite nice, there were a few things about it that I do not prefer. For example you will need the Go language toolchain to be able to utilize this generator. While that may not seem like a burden to some, it was not preferred for myself and others whom I discussed this with.

Having Go as an extra toolchain for a simple website functionality seemed to be a persistent pain for those of us who generated our websites and blogs statically using tools like Org, Haunt, M4, or Hugo (although Hugo, itself, is implemented in Go). One of the primary benefits of implementations in Org or Haunt was the ease of extensibility. You can easily write what is missing and evaluate the dynamic Emacs Lisp or Scheme to provide the functionality, all out-of-the-box!

With this in mind, some friends and I set out to take the idea of openring and reimplement it ourselves, without creating a direct port. Originally this project was called org-blogfeed, but was quickly renamed to org-webring at the suggestion of Amin Bandali. The implementation of org-webring fixes itself around Emacs Lisp (the implementation language of Org), and the Org format itself! Suddenly, we were able to replicate the advantages of having a sharable blog feed from parsed and generated Org files!

The benefits also extended by simply using the platform of Org. Because Org is so broad in its appeal and approach, people using Hugo could take the org-webring implementation and use ox-hugo in order to have the result on their Hugo-based webpages.

Below is a demonstration of org-webring, using my RSS feed as the sole input while demonstrating some of the optional customizable features:

(let ((org-webring-items-total 3) ; default 3.
      (org-webring-items-per-source 3) ; default 1.
      (org-webring-header "Posts from other blogs I follow...")
      (org-webring-display-generation-time t)
      (org-webring-urls '("")))

Reflections on IRC, and Pain with Telegram

Singing Praises, Crying Woes IRC is one of those networking and communication protocols that ages well with the internet. Free software lovers, developers, and casual netizens (especially those born before the millenium) have created the infrastructure for discussing topics we are passionate about. Freenode and OFTC both have systematically helped structure not only project coordination and collaboration, but have created lasting ties between people as free software is an inherently social act. IRC repr…

Sourcehut: Status Update: org-webring

What is new? It has been almost a few weeks since the initial announcement of org-webring, and the response has been great! I have have many great conversations with fellow GNU Emacs citizens about the project, and much to my surprise there have been people persuaded to switch to Org for their website in-part to this neat utility. Obviously the bulk of the benefit will come from the Org-tooling, itself. However, I can not help but feel at least somewhat happy that people have found the project to be an …

This article is an overview of the features of OCaml and the rich type system it uses. The target audience of the article is for people who have familiarity with programming in a statically-typed environment, and understand at least conceptually what a type system is used for. This is not an introduction to functional programming, nor the core syntax/libraries of OCaml.

2.1 Implementation

Visually, openring and org-webring have many similarities. This was done on purpose, as our default stylesheet was taken from the openring implementation on Drew DeVault’s website. It is nice, plain, and easily customizable. There are a few differences, however.

Disregarding the obvious alignment choices (left versus right), we also fold the flex boxes for better visual support on mobile devices, like so:

@media screen and (max-width: 600px) {
    .org-webring .org-webring-articles {
    display: flex;
    flex-direction: column;
@media screen and (max-width: 600px) {
    .org-webring .org-webring-article {
    flex: 1 1 0;
    display: flex;
    flex-direction: column;
    margin: 0 0.5rem;
    margin-bottom: 0.5rem;
    padding: 0.5rem;
    border: 0.1rem black solid;
    border-color: black;

Internally, there are many differences barring org-webring from being considered a port in the legal sense. Our implementation does not derive any programming choices from openring. This comes with some benefits, as well as some work-in-progress decisions to consider for future.

2.1.1 Sanitization

At present, the sanitizer for org-webring is not as strict, nor as elegant as the implementation in Go. In openring, Drew opted to use a Go sanitizer called bluemonday3.

A redux of the Go implementation is as follows4:

policy := bluemonday.StrictPolicy()

summary := runewidth.Truncate(
    policy.Sanitize(raw_summary), *summaryLen, "…")

Where as the redux sanitization in Emacs Lisp is as follows5:

(let ((desc-sanitized
         (insert (org-webring--feed-text-prop item 'description))
         (apply #'concat (dom-strings
                          (libxml-parse-html-region (point-min)
  `(div :class "org-webring-article"
        (p :class "org-webring-article-summary"

The sanitizer in the org-webring implementation is basically taking an apply method, and removing all of the known DOM elements defined in the dom GNU Emacs library6 to return a sanitized string. This implementation method is almost assuredly not as precise as what is offered in bluemonday, however the method is taking the XML elements directly and basically doing the same job.

2.1.2 Modification

There are similarities and differences here. For example, in order to appropriately modify many parts of openring, one must first modify the in.html file. Many of the customizations are trivial, of course but the result could perhaps be cleaner by simply setting those customizations directly in the Emacs Lisp environment. Touching the HTML file directly seems like less of a fool-proof option, in my opinion.

In openring, the articles get generated using the range method, appropriately assigning the number of articles you wish to be displayed to the in.html file, and then producing a result with all of your formatted expectations (header, title, date string, attribution)7:

<section class="webring">
  <h3>Articles from blogs I follow around the net</h3>
  <section class="articles">
    {{range .Articles}}
    <div class="article">
      <h4 class="title">
        <a href="{{.Link}}" target="_blank" rel="noopener">{{.Title}}</a>
      <p class="summary">{{.Summary}}</p>
      <small class="source">
        via <a href="{{.SourceLink}}">{{.SourceTitle}}</a>
      <small class="date">{{.Date | datef "January 2, 2006"}}</small>
  <p class="attribution">
    Generated by
    <a href="">openring</a>

In org-webring, these parameters can be evaluated on-the-fly without recompilation using the defcustom/setq binding methods.

(defcustom org-webring-items-total 3
  "The total number of items that should be in the webring."
  :group 'org-webring
  :type 'integer)

(defcustom org-webring-items-per-source 1
  "How many items should be extracted from each RSS feed."
  :group 'org-webring
  :type 'integer)

(defcustom org-webring-header "Posts from other blogs I follow..."
  "The text of the webring header."
  :group 'org-webring
  :type 'string)

(defcustom org-webring-attribution
  '("org-webring" . "")
  "Association connecting the name of the program used to
generate the webring to its URL to be displayed at the bottom
of the webring."
  :group 'org-webring
  :type '(cons (string :tag "Name")
               (string :tag "URL")))

(defcustom org-webring-urls '()
  "The links for the RSS feeds to be scraped for items."
  :group 'org-webring
  :type '(repeat string))

(defcustom org-webring-description-max-length 512
  "The maximum length of an item's description."
  :group 'org-webring
  :type 'integer)

(defcustom org-webring-timestamp-feed-format "%a, %d %b %Y"
  "The format string for the publish dates of feed items. Uses
the same '%'-sequences as `format-time-string'."
  :group 'org-webring
  :type 'string)

(defcustom org-webring-timestamp-generate-format "%a, %d %b %Y -- %R"
  "The format string for the generation of the webring. Uses
the same '%'-sequences as `format-time-string'."
  :group 'org-webring
  :type 'string)

3 I have the choice, which one should I use?

Perhaps surprisingly to some, I think this is a personal matter. What you choose should be to serve your own best interest as a programmer or somebody who runs a website. When using openring, you must use the Go toolchain. The benefit here is it is quite portable, however Emacs Lisp comes with all Emacs environments and is almost equally as portable. It really comes down to whether you like Org (and Emacs, by extension) or not. You could, of course, use Org and org-webring for just the webring and include the result of the HTML file in any HTML-based result you want, but that takes the fun and integration out of the equation.

In my opinion, you should choose the one you feel has the better toolchain, methods of using it, and will be developed in a direction consistent with your values. Both are free software, so at worst-case you may find yourself trying both! They are both decent pieces of software!

4 Next steps

There are a few things we wish to tackle in the future with org-webring. Currently the software only supports RSS feeds. While I am partial to RSS feeds as I feel the XML format is superior, there will be a felt gap for some users who wish to have support for ATOM. Currently, without official implementation, you can use an ATOM->RSS converter and host the RSS content yourself but that is cumbersome thus warranting a better solution.

  • DONE: Support ATOM feeds.

In the future, we will also want to consider a more strict and distinct sanitizer for XML/ATOM parsing. As it stands, the sanitizer is effective but it is not elegant.

We are also considering making it possible to use Emacs Lisp to generate a CSS stylesheet for inclusion in the website. One of my griefs with openring was that you had to touch the in.html file, and while org-webring does spare you from this task, you are still required to touch the org-webring.css file if you wish to make style modifications.

It may be possible to fetch RSS (and eventually ATOM) feeds asynchronously, but currently the synchronous/asynchronous private functions used in GNU Emacs url-insert-file-contents public function is not truly synchronous nor asynchronous (in the conventional sense). So in order to appropriately apply such a change, we would need to first discuss possibilities with the GNU Emacs maintainers/community, and see about implementing our own way of doing this if needed.

Most projects use the glorious texinfo package to generate and aid in distribution of documentation. Currently, we are relying on our ORG->MD parser-generator to supply the functionality of easily accessible web documentation. Eventually we need to deprecte our current method and drop-in a texinfo replacement.

Lastly, as GNU Emacs is slowly and incrementally switching to default lexical binding, we should check for possible regressions and make pre-empt this by making it a default for the package.

I am sure there are more hidden bugs, though we have taken a lot of effort (as well as trial and error) to work around any which we have noticed.

5 Where to get it

Currently you will have to do a git checkout to acquire org-webring.

$ git clone

There are plans to add this package to GNU Guix, and eventually consider attributing it to ELPA.
