“apps.gnome.org” is Online!

Our Apps for GNOME website is now available at apps.gnome.org! It features the best applications in the GNOME ecosystem. Let’s quickly get into the most exciting aspects of Apps for GNOME.

    • Focus on participation. The app pages are designed with a focus on getting users involved in the development of the application. Whether it is feedback, translation, or financial support of the project. Apps for GNOME offers a lot of ways to get involved in app development.
    • Internationalization. This website is the first source that provides translated information about apps in the GNOME ecosystem. This is another small step towards lowering the barrier for getting into using and contributing to GNOME.
    • Up-to-date information. Apps for GNOME almost exclusively relies on existing metadata that, for example, are used in Software or on Flathub. Therefore it does not require extra work for app maintainers to keep information up-to-date. Better yet, Apps for GNOME is an additional incentive for maintainers and translators to optimize and translate that information.
    • Featuring apps that don’t fit on Flathub.  It’s not technically feasible to distribute apps like Software, Files, or Terminal on Flathub. Apps for GNOME gives those apps the web presence they are missing out on Flathub.

We certainly hope to extend those aspects in the future as this announcement only concludes a rapid development cycle of fewer than eight weeks from the first idea until today. We are looking forward to your feedback, and ideas, and contributions to this project!

If you are interested in some background information you can check out my previous blog posts. Let’s conclude with an attempt to catch up with acknowledgments: Kind thanks to Bilal and Felix for providing an AppStream library and libflatpak bindings for rust. Thanks also to all the translators that make such internationalized project possible in the first place. Last but not least, a huge shoutout to Andrea and the rest of the infrastructure team for the prompt support in realizing this project and keeping GNOME online. You folks are the best :)

Get set: Apps for GNOME on its mark

A week ago I proposed an “Apps for GNOME” website. After quite some positive feedback and some more tweaks, we are pretty close to launching the first version. If you are not happy with how your app looks on the page or you want to help with optimizing “Apps for GNOME” here are a few things that you can do. If you have any further questions, ideas, or just want to complain about the writing style of this post feel free to ping me anywhere you can find me or to just drop me an issue.

Available for translation

Almost all strings in Apps for GNOME are translatable now. You can check the apps-for-gnome module translation status over at Damned Lies. Be aware, that all app-specific strings will not appear in the apps-for-gnome module! Most apps have their own module in Damned Lies where you will find the respective strings that are used on the Apps for GNOME page. If you want to work on the translation of those app details, you have to consult the respective app module. Also note, that some apps do not use the GNOME translation infrastructure.

Make it short and crisp

The text that gets below the app name is called “summary” in the metadata. The upcoming version of Software expects this to be a snappy description of your app. And so does Apps for GNOME. The guidelines for metadata are not finalized but if you want your app to look good we currently recommend the following: Keep it short – 35 characters or less. Pique people’s curiosity. Use imperative if possible (e.g. “Browse the web” instead of “A web browser”). And finally, avoid technical details and environment designations like “for GNOME.”

Finding your color balance

Like Software I’m trying to extract a neat color scheme for your app from the app icon. While even a broken clock is right twice a day that still leaves us with a lot of apps where the silly algorithm gives us an ugly color scheme or one that looks bad with the app icon on top of it. However, you are the person that can decide your app’s fate … and color scheme. You just have to add, at least two, colors to your metadata.xml like that:

  <value key="GnomeSoftware::key-colors">[(124, 53, 77), (99, 16, 0)]</value>

The interpretation of Software might be different, but Apps for GNOME uses the first value as primary (background) color and one of the other entries as secondary (text) color. You can find those two colors as CSS variables on the app page if you want to try out your new colors with your browser’s inspector first.

By the way, if you are happy with the colors for your app, you don’t have to add this key to your metadata.

Update: The previous explanation of key-colors conflicted with the way Software uses them. Please use the instructions on the Software Wiki instead!

Want to show your face?

The “Get to know us” section uses data from your GitLab account. See below for more details. If you are a maintainer and want to show some information about you in this section, maybe it’s time to update your GitLab profile and upload a nice photo of yours.

Speaking of photos: While this might contradict the appstream docs, please do include the window shadows in your screenshots.

Maintainers are dope

DOAP files are quite neat for multiple reasons. They make your App show up with the defined name in Builder. Inside the GNOME GitLab group, they even manage repository access for maintainers. And in Apps for GNOME they determine who shows up in the “Get to know us” section. GNOME Core apps should be all set since a .doap-file is mandatory for them. GNOME Circle maintainers however should pay attention now!

If you don’t have a .doap-file in your repository, you should really consider creating one right now. Otherwise, the “Get to know us” section won’t appear on your app’s page. And adding a .doap-file it’s quite simple too! You just have to ensure that the file name equals the project’s GitLab (and in the future possibly GitHub) path. For example, if your app lives in World/my-app you need a my-app.doap file in your git repo’s root. You can probably just copy a random existing .doap-file to get started. But, watch out one more time!

The traditional .doap-files in GNOME use a “gnomeid” to identify maintainers. This mysterious token is mostly reserved for GNOME Foundation members and it also involves some trickery to link it to GitLab accounts. Therefore, we decided that outside of the GNOME GitLab group we will use a different method to link maintainers to GitLab accounts. And this method looks like this:

    <foaf:accountServiceHomepage rdf:resource="https://gitlab.gnome.org"/>

This format is a bit involved for defining two keys but, I think you will get the hang of it and hey, it uses an existing standard! All hail the two-thousands and its dream of the semantic web! You can have a look at this real-world example if you are still confused.

Where even is your repository?

Actually, our page generator is starting from a list of app ids. There is no certain way to know what your app’s repository is. We have to guess. And the safest way to ensure that we find your repository is to add a proper URL for your bug tracker to the metadata. This would look something like this:

<url type="bugtracker">https://gitlab.gnome.org/World/decoder/-/issues</url>

That’s it for today …

There are so many aspects to Apps for GNOME that we cannot possibly aim for having every detail perfected for the launch. But I am already quite happy with the current state. Stay tuned for more updates though and let me know if you want to get involved.

An “Apps for GNOME” website

TL;DR: Something like an “Apps for GNOME” website might exist pretty soon. This changes nothing about existing pages. You can have a look at the current state of the website. Feedback and contributions are more than welcome.

Currently, most apps in the GNOME ecosystem are represented by a wiki page or README at our GitLab instance. All the information in these wiki pages has to be updated manually in parallel to the other sources like the AppStream MetaInfo file, the screenshots, or the DOAP file. I was no longer motivated to do this work manually for my app and started looking for alternative solutions. I quickly wrote a small script that generates an app page. After showing the generated page around, several people proposed to provide such app pages in a centralized fashion for GNOME.

What app pages could provide

Having a standardized page for apps could provide a bunch of useful information to users and contributors. My main focus is less about technical information but more about how to get engaged, how to fill an issue or how to get in touch with the community around an app. Introducing the people that are involved in the app’s development could help to build up an emotional connection to the app and in the end maybe incentivize users to contribute their time or money to the project.

In contrast to the Flathub pages, a GNOME specific apps website could not only emphasize slightly different aspects of an app. Rather, a separate website would also allow us to provide a GNOME specific curated list of apps. This would make it easier for people to search for apps that are suitable for their desktops.

Apart from that, there are a bunch of apps that will not be available via Flathub for technical reasons (e.g. Settings, Terminal, Files) in the foreseeable future. If we could integrate them in these app pages as well they might profit from more visibility as a project.

One last thing that this project could maybe rectify is that neither our wiki nor the Flathub pages currently provide translated app information. In practice, this means, if you are searching the web for a GNOME app you probably only have a chance of reaching a somewhat “official” landing page for an app if you searching in English. As Shaun McCance has recently outlined in his GUADEC talk about documentation, online search is something that we should cover if possible. Notably, translations for AppStream MetaInfo are available in GNOME Software. However, currently, the data is hardly accessible anywhere else.

A sled dog makes an attempt

As it turns out, I’m not the first person with the idea to automatically generate pages for apps in GNOME. However, as far as I know, nobody has tried it yet. But so far, it does not look like an impossible feat. Meet “codename malamute.”

Detail page for the Fragments app. A colored header with app description and an "get engaged" section below.

Malamute starts by collecting a list of all the core and GNOME Circle apps from their official lists. Next, it uses the pre-build metainfo file from Flathub to obtain the metadata, including translations, for every app. Those data are, for example, supplemented by the maintainers’ GitLab profile information. This data is fed into tera, a Jinja2-like template engine. Within less than one minute run time – and by passing over the rust compile time – we end up with about 150 MB of static page data.

What’s next

I already received some early feedback on the project. A small number of real-world tests seem to suggest that the page in it’s current form could already be of use for GNOME users. For example by making them aware of the number of useful apps that suddenly appeared as part of GNOME Circle.

The purpose of this post is mainly to reach out for broader feedback. I don’t have any conflicts with existing infrastructure on my radar, but please let me know if I am overlooking something. Maintainers can still decide to keep their app wiki pages or to role individual pages in parallel to this project. They can be (and mostly already are) linked from the apps detail page.

A topic I personally feel very uncertain about is reusing personal data from GitLab or GitHub user profiles. In theory, all those data are public, but they are presented in a different context on app pages. It might even be legally required for people to opt-in to this feature. It would be much appreciated if someone could help me with this question.

There are a ton of technical details that still need to be implemented. The design team already indicated that they might have some words to say about my attempts at designing those pages ? Another issue is the quality of metadata. I think we should by no means underestimate the quality of the data that already exist! But, this is likely an area that – combined with a shiny new design for Software in GNOME 41 – might gain some new traction.

If you want to give feedback or get involved you can use the issue tracker, hit me up on Rocket.Chat or Matrix or ping me on Twitter. Big thanks to everyone who helped with this project so far, especially Alexandre, Tobias, Zander, and of course everyone I forgot to list here!

PS: To avoid further questions about the codename, the official name will probably change to something more generic in the future.
