WCEU23 – Day 2

My second day of the main conference part of WordCamp Europe 2023 was hampered slightly by a late start on my part.

Dan, sweating, with an actively-used dancefloor in the background. — I can’t say for certain why I woke up mildly hungover and with sore knees, but I make an educated guess that it might be related to the Pride party I found myself at last night.

Still, I managed to get to all the things I’d earmarked for my attention, including:

Gutenberg collaborative editing experience

I’m sure I can’t be the only person who’s been asked “why can’t the (or ‘shouldn’t the’) WordPress post editor let multiple people edit post at the same time”. Often, people will compare it to e.g. Google Docs.

A man in a blue shirt stands on a large stage. — I can’t begin to speculate how often people must ask this supposedly-trivial question of Dawid Urbański, possibly the world’s expert on this very question.

Dawid summarised the challenging issues in any effort to implement this much-desired feature. Some of them are examples of those unsolved problems that keep rearing their heads in computer science, like the two generals’ problem, but even the solvable problems are difficult: How does one handle asynchronous (non-idempotent) commutative operations? How is the order of disparate actions determined? Which node is the source of truth? If a server is used, where is that server (with a nod to quite how awful the experience of implementing a Websockets server in PHP can be…)? And so on…

Slide showing a timeline in which two participants A and B send an update to one another, but neither can be sure whose update was made first. — Slides showing simplified timelines of parties communicating with one another in ambigous ways

I really appreciated Dawid’s reference to the various bits of academic literature that’s appeared over the last four decades (!) about how these problems might be solved. It’s a strong reminder that these things we take for granted in live-updating multi-user web applications are not trivial and every question you can answer raises more questions.

There’s some great early proof-of-concepts, so we’re “getting there”, and it’s an exciting time. Personally, I love the idea of the benefits this could provide for offline editing (perhaps just because I’m still a huge fan of a well-made PWA!).

The future of work is open

James Giroux’s goal: that we all become more curious about and more invested in our team’s experiences, from a humanistic standpoint. His experience of companies with organic growth of software companies is very, very familiar: you make a thing and give it away, then you need more people, then you’ve somehow got a company and it’s all because you just had an idea once. Sounds like Three Rings!

A man in a white t-shirt and dark jacket stands on a stage in front of a screen; the bottom line of the words on the screen can be seen to read "Work is Open". — Financial success is not team success, as Twitter shows, with their current unsustainable and unhappy developer culture, James reminds us.

James was particularly keen to share with us the results of his Team Experience Index research, and I agree that some of the result are especially exciting, in particularly the willingness of underrepresented groups, especially women, to enagage with the survey: this provides hugely valuable data about the health of teams working in the WordPress space.

A slide showing demographic details: 28% say that they represent a historically underrepresented group, 55% are in North America, 67% provided a gender that was not "male". — The statistician in me immediately wanted to know how the non-response rate to these (optional) questions varied relative to one another (if they’re very different, putting these pie charts alongside one another could be disingenuous!), but I’m tentatively excited by the diversity represented anyway.

“We have this project that we work with and contribute to, that we love,” says James, in an attempt to explain the highly-positive feedback that his survey respondents gave when asked questions about the authenticity of their purpose and satisfaction in their role.

A man on a stage stands in front of a slide listing strengths and opportunities resulting from the survey. — Again, my inner statistician wants to chirp up about the *lack of a control group*. The data from the survey may well help companies working within the WordPress ecosystem to identify things we’re doing well and opportunities for growth, but it’d also be cool to compare these metrics to those in companies *outside* of the WordPress world!

So, what do we do with these findings? How do WordPress-ey companies improve? James recommends that we:

Get better are showing what recognition, celebration, and career growth looks like,
Improve support and training for team leaders to provide them with the tools to succeed and inspire, and
Bridge the gap between leadership and team members with transparent, open dialogue.

Good tips, there.

The Big Photo

A WordCamp tradition is to try to squeeze every willing participant into a photo. Clearly with the size that these events are, nowadays, this requires some wrangling (and, in this case, the photographers standing atop the roof of a nearby building to get everybody into frame).

An enormous crowd shuffles tightly into a courtyard. A trio of blue-shirted photographers stands atop a building opposite them. — Like herding cats, trying to get several hundred people to line up where you want them for a photograph is an exercise in patience.

I’ll have to keep an eye out for the final picture and see if I can find myself in it.

What is new in CSS?

I always find that learning about bleeding edge CSS techniques makes me feel excited and optimistic, perhaps because CSS lends itself so well towards a progressive enhancement approach to development: often, you can start using a new technique today and it’ll only benefit, say, people using a beta version of a particular browser (and perhaps only if they opt-in to the applicable feature flag). But if you’ve designed your site right then the lack of this feature won’t impact anybody else, and eventually the feature will (hopefully) trickle-down into almost everybody’s Web experience.

Anyway, that’s what Fellyph Cintra says too, but he adds that possibly we’ve still not grown out of thinking that browsers take a long time between versions. 5 years passed between the release of Internet Explorer 6 and Internet Explorer 7, for example! But nowadays most browsers are evergreen with releases each month! (Assuming we quietly ignore that Apple don’t sent new versions of Safari to old verisons of MacOS, continuing to exacerbate a problem that we used to see with Internet Explorer on Windows, ahem.)

A man on a stage with his arm out in greeting to the crowd in front of him. — Fellyph told us about how he introduced `<dialog>` to his team and they responded with skepticism that they’d be able to use it within the next 5 years. But in fact it’s already stable in every major browser.

An important new development may come from Baseline, a project to establish a metric of what you can reliably use on the Web today. So a bit like Can I Use, I guess, but taken from the opposite direction: starting from the browsers and listing the features, rather than the other way around.

Anyway, Fellyph went on to share some exciting new ideas that we should be using, like:

object-fit and object-position, which can make the contents of any container “act like” a background
aspect-ratio, which I’m already using and I love, but I enjoyed how Fellyph suggested combining the two to crop images to a fluid container on the client side
scroll-behavior: smooth, which I’ve used before; it’s pretty good
clamp, which I use… but I’m still not sure I fully grok it: I always have to load some documentation with examples when I use it
@container queries, which can apply e.g. (max-width: ...) rules to things other than the viewport, which I’ve not found a need for yet but I can see the value of it
@layers, which grant an additional level of importance in the cascade: for example, you might load a framework into a layer (with @import url(...) layer(framework)) which is defined as a lower-priority than your override layer, meaning you won’t have to start slapping !important all over the shop
@media (400px <= width <= 600px)-style media queries, which are much easier to understand than min-width: if you’re used to thinking in a more-procedural programming language (I assume they work in container queries too!)

Fellyph Cintra stands in front of a large screen showing a slide that introduces himself to his audience: "Front-end Lead at Digitale Methode & Google Developer Expert @fellyph" — …

It’s also worth remembering:

@supports, which is badass and I love and use it already (it was especially useful as display: grid began to roll out and I wanted to start using it but needed to use a fallback method for browsers that didn’t support it yet
:has(), which I’ve long thought is game-changing: styling something based on what it contains is magical; not really suitable for mainstream use yet without Firefox support, though (it’s still behind a feature flag)! Fellyph sold me on the benefit of :not(:has(...)), though!
Nesting, which again doesn’t have Firefox support yet but provides SCSS-like nesting in CSS, which is awesome
Scroll-driven animations, which can e.g. do parallax effects without JavaScript (right now it’s Canary only, mind…), using e.g. animation-timeline: and animation-range: to specify that it’s the scroll position within the document that provides the timeline for the animation

And keeping an eye on upcoming things like text-balanced (which I’m already excited by), popover, selectmenu, view transitions (which I’ve been experimenting with because they’re cool), and scoped style.

Fellyph was at least as inspiring as I’d hoped.

Stop blocking my thread

For my second workshop, I joined Google’s Adam Silverstein to watch him dissect a few participants’ websites performance using Core Web Vitals as a metric. I think I already know the basics of Core Web Vitals, but when it comes to improving my score (especially on work-related sites with unpleasant reliance on heavyweight frameworks like React, in my experience).

A man stands at a podium. — In an early joke, Adam pointed out that you can reduce JavaScript thread blocking by removing JavaScript from your site. A lot of people laughed, but frankly I think it’s a great idea.

We talked a lot about render blocking (thanks to JS and CSS in the <head>), thread blocking (by scripts, especially those reacting to user input), TTFB (relating to actual network and server performance, or at least server-side processing), TBT (the time between FCP and TTI), and the upcoming change to measure INP rather than FID. That’s a lot of acronyms.

The short of it is that there are three pillars to Core Web Vitals: loading (how long until the page renders), interactivity (how long until the page responds to user interaction), and stability (how long it takes for the page to cease layout shifts as a result of post-load scripts and stylesheets). I was pleased that Adam acknowledged the major limitation of lab testing resulting from developers often using superior hardware and Internet connections to typical users, and how if you’re serious about performance metrics you’ll want to collect RUM data.

Adam explaining Render-Blocking CSS. — The fastest way to improve rendering performance is to put fewer obstacles in the way of rendering.

I came away with a few personalised tips, but they’re not much use for your site: I paid attention to the things that’ll be helpful for the sites I look after. But I’ll be taking note of his test pages so I can play with some of the tools he demonstrated later on.

Variations on a theme: 20 years of WordPress

I couldn’t liveblog this because I spent too much of the session applauding. A few highlights from memory:

Phase 2 (of 4) of Gutenberg is basically complete, which is cool. Some back-and-forth about the importance of phase 4 (bringing better multilingual support to WordPress) and how it feels like it’s a long way away.
Lots of plugging for Five for the Future, which I can get behind.
In the same vein as his 2016 statement that WordPress developers should “learn JavaScript deeply”, Matt leant somewhat into the idea that from today they should “watch AI carefully”; I’m not 100% convinced, but it’s not been stopping me from getting involved with a diversity of AI experiments (including some WordPress-related ones) anyway.
Musings about our community being a major part of why WordPress succeeded (and continues to thrive) unlike some other open source projects of its era. I agree that’s a factor, but I suspect that being in the right place at the right time was also important. Perhaps more on that another time.
Announcement of the next WordCamp Europe location.

Here’s looking forward to WordCamp Europe 2024 in Turin!

WCEU23 – Day 1

The first “full” day of WordCamp Europe 2023 (which kicked-off at Contributor Day) was busy and intense, but I loved it.

This post is basically a live-blog of everything I got up to, and it’s mostly for my own benefit/notetaking. If you don’t read it, nobody will blame you.

Seen from behind, a very long queue runs through a conference centre. — Six minutes after workshop registration opened its queue snaked throughout an entire floor of the conference centre.

Here’s what I got up to:

10 things that all WordPress plugin developers should avoid

David Artiss took the courageous step of installing 36 popular plugins onto a fresh WordPress site and was, unsurprisingly, immediately bombarded by a billion banners on his dashboard. Some were merely unhelpful (“don’t forget to add your API key”), others were annoying (“thanks for installing our plugin”), and plenty more were commercial advertisements (“get the premium version”) despite the fact that WordPress.org guidelines recommend against this. It’s no surprise that this kind of “aggressive promotion” is the single biggest annoyance that people reported when David asked around on social media.

Similarly, plugins which attempt to break the standard WordPress look-and-feel by e.g. hoisting themselves to the top of the menu, showing admin popovers, putting settings sections in places other than the settings submenu, and so on are a huge annoyance to everybody. I get sufficiently frustrated by these common antifeatures of plugins I use that I actually maintain a plugin for my own use that “fixes” the ones that aggrivate me the most!

David raised lots of other common gripes with WordPress plugins, too: data validation failures, leaving content behind after uninstallation (and “deactivation surveys”, ugh!), and a failure to account for accessibility.

David’s promised to put his slides online, plus to write articles about everything that came up in his Q&A.

I’m unconvinced that we can rely on plugin developers to independently fix the kinds of problems that come high on David’s list. I wonder if there’s mileage in WordPress Core reimplementing the way that the main navigation menu works such that all items in it can be (easily) re-arranged by users to their own preference? This would undermine the perceived value to plugin developers of “hoisting” their own to the top by allowing users to counteract it, and would provide a valuable feature to allow site admins to streamline their workflow: use WooCommerce but only in a way that’s secondary to your blog? Move “Products” below “Posts”! Etc.

Where did we come from?

Aaron Reimann from ClockworkWP gave us a tour of how WordPress has changed over the course of its 20-year history, starting even slightly before I started using WordPress; my blog (previously powered by some hacky PHP, previouslier powered by some hackier Perl, previousliest written in static HTML) switched to WordPress in 2004, when it hit version 1.2, so it was fun to get the opportunity to see some even older versions illustrated.

A WordPress site, circa 2004, simulated in a virtual machine. — A WordPress site from 2004 would, of course, still be perfectly usable today. How many JS-heavy/API-driven websites of today do you reckon will still function in 20 years time?

It was great to be reminded how far the Core code has come over that time. Early versions of WordPress – as was common among PHP applications at the time! – had very few files and each could reliably be expected to be a stack of SQL, wrapped in a stack of code, wrapped in what’s otherwise a HTML file: no modularity!

A man wearing a flat cap strides across a stage. — Aaron’s passion for this kind of digital archaeology really shows. I dig it.

There were very few surprises for me in this talk, as you might expect for such an “old hand”, but I really enjoyed the nostalgia of exploring WordPress history through his eyes.

I enjoyed putting him on the spot with a “spicy” question at the end of his talk, by asking him if, alongside everything we’ve gained over the years, whether there’s anything we lost along the way. He answered well, pointing out that the somewhat bloated stack of plugins that are commonplace on big sites nowadays and the ease with which admins can just “click and install” more of them. I agree with him, although personally I miss built-in XFN support…

If you’d have told me in advance that hugging a Wapuu would have been a highlight of the day… yeah, that wouldn’t have been a surprise!

Networking And All That

There’s a lot of exhibitors with stands, but I tried to do a circuit or so and pay attention at least to those whose owners I’ve come into contact with in a professional capacity. Many developers who make extensions for WooCommerce, of course, sell those extensions through WooCommerce.com, which means they come into routine direct contact with my code (and it can mean that when their extension’s been initially rejected by our security scanners or linters, it’s me their developers first want to curse!).

A WordCamp Europe Athens 2023 lanyard and name badge for Dan Q, Attendee, onto which a "Woo" sticker has been affixed. — After a while, to spare some of that awkward exchange where somebody tries to sell me their product before I explain that I *already sell their product for them*, I slapped a “Woo” sticker on my lanyard.

It’s been great to connect with people using WordPress to power the Web in a whole variety of different contexts, but it somehow still feels strange to me that WordPress has such a commercial following! Even speaking as somebody who’s made their living at least partially out of WordPress for the last decade plus, it still feels to me like its greatest value comes from its use for personal publishing.

The feel of a WordCamp with its big shiny sponsors is enormously different from, say, the intimacy and individuality of a Homebrew Website Club meeting, and I think that’s something I still need to come to terms with. WordPress’s success story comes from many different causes, but perhaps chief among them is the fact that it’s versatile enough to power the website of a government, multinational, or household-name brand… but also to run the smallest personal indie blog. I struggle to comprehend that, even with my background.

(Side note, Sophie Koonin says that building a personal website is a radical act in 2023, and I absolutely agree.)

A "Woo" booth, staffed with a variety of people, with Dan at the centre. — My division of Automattic had a presence, of course.

I was proud of my colleagues for the “gimmick” they were using to attract people to the Woo stand: you could pick up a “credit card” and use it to make a purchase (of Greek olive oil) using a website, see your order appear on the app at the backend in real-time, and then receive your purchase as a giveaway. The “credit card” doubles as a business card from the stand, the olive oil is a real product from a real, local producer (who really uses WooCommerce to sell online!), and when you provide an email address at the checkout you can opt-in to being contacted by the team afterwards. That’s some good joined-up thinking by my buddies in marketing!

WordPress extended: build unique websites on top of WP

Petya Petkova observed that it’s commonplace to take the easy approach and make a website look like… well, every other website. “Web deja-vu” is a real thing, and it’s fed not only by the ebbs and flows of trends in web design but by the proliferation of indistinct themes that people just install-and-use.

A woman with long hair, wearing a green t-shirt, stands before a screen on a stage. — How can we break free from web deja-vu, asks Petya. It almost makes me sad that her slides had been coalesced into the conference’s slidedeck design rather than being her own… although on second though maybe that just helps enhance the point!

Choice of colours and typography can be used to tell a story, to instil a feeling, to encourage engagement. Scrolling can be used as a metaphor for storytelling (“scrolly-telling”, Petya calls it). Animation flow can be used to direct a user’s attention and drive focus and encourage interaction.

A lot of the technical concepts she demonstrated – parts of a page that scroll at different speeds, typography that shifts or changes, videos used in a subtle way to accentuate other content, etc. – can be implemented in the frontend with WebGL, Three.js and the like. Petya observes that moving this kind of content interactivity into the frontend can produce an illusion of a performance improvement, which is an argument I’ve heard before, but personally I think it’s only valuable if it’s built as a progressive enhancement: otherwise, you’re always at risk that your site won’t look like you’d hope.

I note, for example, that Petya’s agency’s site shows only an “endless spinner” when viewed in my browser (which blocks the code.jQuery CDN by default, unless allowlisted for specific sites). All of the content is there, on the page, if you View Source, but it’s completely invisible if an external JavaScript fails to load. That doesn’t just happen when weirdos like me disable JavaScript in their browsers: it can happen if the browser interacts badly with the script, or if the user’s Internet connection is ropey, or a malware scanner misfires, or if government censorship blocks the CDN, or in any number of other conditions.

So yeah: uniqueness and creativity are great, and I like what she’s proposing, but not the way she goes about it. The first person to ask a question wisely brought up accessibility, and Petya answered well that accessibility technologies can bridge the gap, but I’d counter that it’s preferable to build accessible in the first instance: if you have to use an aria- attribute it’s a good sign that you probably already did something wrong (not always, but it’s certainly a pointer that you ought to take a step back and check!).

Several other good questions and great answers followed: about how to showcase a preliminary design when they design is dependent upon animation and interactivity (which I’ve witnessed before!), on the value of server-side rendering of components, and about how to optimise for smaller screens. Petya clearly knows her stuff in all of these areas and had confident responses.

State of WordPress security – insights from 2022

Oliver Sild is the kind of self-taught hacker, security nerd, and community builder that I love, so I wasn’t going to miss his talk.

A man in a literal black hat stands in the centre of a large theatre stage. — The number of security vulnerability reports in the WordPress ecosystem is up +328%, Oliver opened. But the bugs being reported are increasingly *old*, so we’re not talking about *new issues being created*. And only 0.3% of bugs were in WordPress Core (and were patched before they were exploitable).

It’s good news in general in WordPress Security-land… but CSRF is on the up-and-up (overtaking XSS) in the plugin space. That, and all the broken access control we see in the admin area, are things I’ll be keeping in mind next time I’m arguing with a vendor about the importance of using nonces and security checks in their extension (I have this battle from time to time!).

But an interesting development is the growth of the supply chains in the WordPress plugin ecosystem. Nowadays a plugin might depend upon another plugin which might depend upon a library… and a patch applied to the latter of those might take time to be propagated through the chain, providing attackers with a growing window of opportunity.

Sankey chart showing 1160 submitted bugs being separated into pending, accepted, invalid, and (eventually) patched. 26% of critical bugs in 2022 received no timely patch. — I love a good Sankey chart. Even when it says scary things.

A worrying thought is that while plugin directory administrators will pull and remove plugins that have longstanding unactioned security issues. But that doesn’t help the sites that already have that plugin installed and are still using it! There’s a proposal to allow WordPress to notify admins if a plugin used on a site has been dropped for security reasons, but it was opened 9 years ago and hasn’t seen any real movement, soo…

I like that Oliver plugged for security researchers being acknowledged as equal contributors to developers on your software. But then, I would say that, as somebody who breaks into things once in a while and then tells the affected parties how to fix the problem that allowed me to do so! He also provided a whole wealth of tips for site owners and agencies to try to keep their sites safe, but little that I wasn’t aware of already.

A large audience of a few hundred people, seen from above, facing left. — Still, good to see this talk get as good an audience as it did, given the importance of the topic!

It was about this point in the day, glancing at my schedule and realising that at any given time there were up to four other sessions running simultaneously, that I really got a feel for the scale of this conference. Awesome. Meanwhile, Oliver was fielding the question that I’m sure everybody was thinking: with Gutenberg blocks powered by JavaScript that are often backed by a supply-chain of the usual billion-or-so files you find in your .node_modules directory, isn’t the risk of supply chain attacks increasing?

Spoiler: yes. Did you notice earlier in this post I mentioned that I don’t use Gutenberg on this site yet?

Typographic readability in theme design & development

My first “workshop” was run by Giulia Laco, on the topic of readable content and design.

A title slide encourages designers to sit on the left (to the right of the speaker), developers to the right (on her left), and "no-coders" in the centre. — Designers to the left of me, coders to the right: here I am, stuck in the middle with you.

Giulia began by reminding us how short the attention span of Web readers is, and how important the right typographic choices are in ensuring that people actually read your content. I fully get this – I think that very few people will have the attention span to read this part of this very blog post, for example! – but I loved that she hammered the point home by presenting every slide of her presentation twice (or more), “improving” the typographic choices as she went along: an excellent and memorable quirk.

Our capacity to read and comprehend a text is affected by a combination of common (distance, lighting, environment, concentration, mood, etc.), personal (age, proficiency, motiviation, accessibility requirements, etc.), and typographic (face, style, size, line length and spacing, contrast, width, rhythm etc.) factors. To explore the impact of the typographic factors, the group dived into a pre-prepared Codepen and a shared Figma diagram. (I immediately had a TIL moment over the font-synthesis: CSS property!)

A presentation of the typography playground, in which the font is being changed. — I appreciated that Giulia stressed the importance of a fallback font. Just like the CDN issues I described above while talking about JavaScript dependencies, not specifying a fallback font puts your design at the mercy of the browser’s defaults. We don’t like to think about what happens when websites *partially fail*, but they do, and we should.

Things get interesting at the intersection of readability and accessibility. For example, WCAG accessibility requirements demand that you don’t use images of text (we used to do this a lot back before we could reliably use fonts on the web, and before we could easily have background images on e.g. buttons for navigation). But this accessibility requirement also aids screen readability when accounting for e.g. “retina” screens with virtual pixel ratios.

Slide showing a physical pixel and a "virtual pixel" representing a real pixel of a different size. — Do you remember when a pixel was the size of a pixel? Those days are long gone. True story.

Giulia provided a great explanation of why we may well think in pixels (as developers or digital designers) but we’re unlikely to use them everywhere: I’d internalised this lesson long ago but I appreciated a well-explained justification. The short of it is: screen zoom (that fancy zoom feature you use in your browser all the time, especially on mobile) and text zoom (the one you probably don’t use, or don’t use so much) are different things, and setting a pixel-based font size in the root node wrecks the latter, forcing some people with accessibility needs to use the former, which is likely to result in vertical scrolling. Boo!

I also enjoyed seeing this demo of how the different hyphenation-points in different languages (because of syllable stress) can impact on your wrapping points/line lengths when content is translated. This can affect any website, of course, because any website can be the target of automatic translation.

Plus, Giulia’s thoughts on the value of serifed fonts (even on digital displays) for improving typographic readability of the letters d, b, p and q which are often mirror- or rotationally-symmetric to one another in sans-serif fonts. It’s amazing to have something – in this case, a psychological letter transposition – pointed out that I’ve experienced but never pinned down the reason for, before. Neat!

It was a shame that this workshop took place late in the day, because many of the participants (including me) seemed to have flagging energy levels!

Altogether a great (but intense) day. Boggles my mind that there’s another one like it tomorrow.

WCEU23 – Contributor Day

Among the many perks of working for a company with a history so tightly-intertwined with that of the open-source WordPress project is that license to attend WordCamps – the biggest WordPress conferences – is basically a given.

Dan, wearing an Automattic "Let's make the Web a better place" t-shirt, stands in front of a banner welcoming attendees to WordCamp Europe Athens 2023. — So yeah, right now I’m in Athens for WordCamp Europe 2023.

It’s frankly a wonder that this is, somehow, my first WordCamp. As well as using it¹ and developing atop it², of course, I’ve been contributing to WordPress since 2004 (albeit only in a tiny way, and not at all for most of the last decade!).

A table placeholder labelled "WP-CLI". It and s handful of Coke cans and disposable coffee cups are picked-out in colour on an otherwise monochrome and blurred picture. — If you already know what WP-CLI is… let’s be friends.

Today is Contributor Day, a pre-conference day in which folks new and old get together in person to hack on WordPress and WordPress-adjacent projects. So I met up with Cem, my Level 4 Dragonslayer friend, and we took an ultra-brief induction into WP-CLI³ before diving in to try to help write some code.

Dan takes a selfie from a round table covered in laptops, with people hacking at them. — Contributor Days are about many things, but perhaps their biggest value comes from lowering the barrier to becoming a *new* contributor to an open-source project by sitting you right next to somebody who already knows it well.

So today, as well as meeting some awesome folks, I got to write an overly-verbose justification for a bug report being invalid and implement my first PR for WP-CLI: a bugfix for a strange quirk in output formatting.

Screenshot showing a user running `wp plugin update --all --no-color` but the output putting the word "Success" in green. — The bug I fixed is slightly hard to describe (and even harder to explain why it *matters*), but here’s a summary: when you run a WP-CLI command that first displays a table and then the result, the result is likely to always appear in colour even if you specify `--no-color`.

I hope to be able to continue contributing to WP-CLI. I learned a lot about it today, and while I don’t use it as much as I used to in my multisite-management days, I still really respect its power as a tool.

Footnotes

¹ Even with the monumental stack of custom code woven into DanQ.me, a keen eye will probably spot that it’s WordPress-powered.

² Perhaps my proudest “built on WordPress” moment was my original implementation of OpenID for WordPress, back in 2005, which is completely obsolete now. But I’ve done plenty of other things, both useful (like the multisite installation used by the University of Oxford) and pointless (like making WordPress a CMS for Gemini, Gopher, and Finger) too over the last 20 years.

³ WP-CLI is… it’s like Drush but for WordPress, if that makes sense to you? If not: it’s a multifaceted command-line tool for installing, configuring, maintaining, and managing WordPress installations, and I’ve been in love with it for years.
