The future of WeasyPrint

[grewn0uille]

Hello!

As you may have noticed, there was some activity on the repo. But no release.
Some "the project is no longer maintained by Kozea". But who?

So today is answer-day!

Like it has sometimes been said, a new organization maintains this project: CourtBouillon.

CourtBouillon is composed of @liZe and myself, @grewn0uille.

You can visit our website by starting with this article, and join us on Twitter, Gitter and OpenCollective :)

Have a nice day!

First of all thank you so much for a great repo.

I noticed you are working on your own pdf writer in pydyf branch to remove Cairo, may I know is there any plans on release? How stable this branch is now?

[grewn0uille]

Hello!

After the releases last week, we prepared a roadmap for the projects.

You can have a look at it on our website :)

Have a nice day!

Hello!

We just published a quick update on where we are on the "get rid of Cairo" part, what has been done and what still needs to be done.

[grewn0uille]

Hello!

We just released WeasyPrint 52.2, one of the last release with Cairo!
We also released pydyf and so the master branch is now working with it.
Cairo version is now on 52.x branch.

You can discover the differences between the two versions on our blog :)

Hello!

We sometimes talk about our OpenCollective page. But we never said why we chose OpenCollective nor why donations help to have better software.
It’s finally done in our last article!

[grewn0uille]

Hello!

Thanks to expert Germany, line-clamp has been implemented in WeasyPrint. You can use this property with the master branch and it has also been backported in the Cairo version.

There is a new release (with Cairo) for this new feature! 🎉

You can read more about this feature in our blog article 😉

[grewn0uille]

Hello!

Thanks to Simonsoft, leader() is now implemented in WeasyPrint (only on the pydyf version aka master). You can read more in our blog article 😀

Also, we released WeasyPrint 52.4 (with Cairo). This release fixes a crash occuring with line-clamp and makes ellipsis nicer with hyphenation.

Hello!

You may know it (or not), this week is the 10 years anniversary of WeasyPrint 🎉
For this occasion, we just released a beta of version 53!

To know more about this beta, you can read our article 😀

That’s the first release without Cairo. Please give it a try and don’t hesitate to report the bugs you found 🐛

[grewn0uille]

Hello again!

We prepared a short survey (CLOSED) to know more about your needs with WeasyPrint.
This survey is open until the end of May.
Your answers will help us to improve WeasyPrint!

Thanks for taking time to answer 😀

I'm so glad that WeasyPrint now supports SVGs in v53. I plan to use the software to create labels with barcodes, and it's just so much more efficient to use an SVG (also reduces file size).

On macOS, I've found v53 to be bug-free so far (using the CLI as I'm interfacing via PHP). The kerning issues appear to be gone, and the output PDF is quite literally perfect in every way.

The only thing I noticed was file size – but this was due to the font being embedded. A tiny label seems to contain the entire font (Inter), resulting in a 1MB file. For the time being, I am using GhostScript to convert the text to outlines, which results a file less than 10% the original size.

As an aside, I also maintain a Laravel package for WeasyPrint and will need to update it to omit the --format argument, as it is no longer included in v53. It would be nice, however, if it would not produce an error when provided…

Great work on this!

According to our tests, the new version of WeasyPrint is usually on par or much better than Cairo for PDF size. Is it possible for you to share your document (both HTML/CSS and generated PDF) with us?

Deprecated options have been re-added with a deprecation warning (see b476f2f), will be available in versions 53.x, and will probably be removed from version 54.0. (Exception: -f png now raises an error.)

You're welcome :)

I'm quite sure the font data is the issue at hand (the font is also loaded as a system font, not from an external source). That said, I can share the HTML+CSS+PDF with you. Would it be possible for me to send it via email? As much as the document doesn't include confidential information, it is company policy to share privately.

Deprecated options have been re-added with a deprecation warning…

That's great! However, I see that other args have been deprecated or changed, so I may as well have the package make decisions based on the actual version when v53 stable is released. Out of interest, do you know when that might be? 🙃

[liZe]

I was wondering what is behind the decision of not implementing such a modern browser feature? I can understand grid and all that new fancy stuff not being there, but flexbox is widely adopted. :)

The main reason is the lack of time and money. Nothing unusual 😄.

Having a good support of Flexbox requires a lot of work, including the 8-year-old #36 bug. As we don’t work (yet?) full time on WeasyPrint, it takes time. CSS is quite easy to use, but quite complex to implement, as you can imagine.

A better Flexbox support is in the roadmap, as explained in the WeasyPrint survey article. So, it may come in the next version, that will be released … when it is ready 😉. When a bug is 8 years old, it means that its complexity requires many weeks or months of hard work to be solved. And solving this bug is just a requirement for a good support of Flexbox and Grid, we need even more work to implement these layouts.

So… Don’t hesitate to help us by opening bug reports and pull requests, or by joining our OpenCollective campaign. We’ll do our best to provide a nice Flexbox support soon.

Thanks a lot for the in-depth answer. I am always curious, what lays behind such decisions, because I know its for sure never "we dont want to do it" :)

I will see what I can do to help out on supporting these nifty handy css properties!
Cheers!

Some "the project is no longer maintained by Kozea". But who?
Like it has sometimes been said, a new organization maintains this project: CourtBouillon.

Many thanks for your explanation, @grewn0uille.

I think it would make sense to move all projects effectively maintained by @CourtBouillon, from @Kozea to them.

Many thaks for your help and your excellent work.

[grewn0uille]

Hi @ousia,

Indeed moving WeasyPrint and all its dependencies in the CourtBouillon org would make more sense.
However, due to some legal stuff, it’s not possible yet. But we’ll do that as soon as we can!

[ousia]

Many thanks for your reply, @grewn0uille (and sorry for the delay in mine).

Hello!

WeasyPrint v63 has been released 🎉

WeasyPrint now supports CSS Color Level 4, page groups (thanks to the financial support of Code & Co.), submit and radio inputs for PDF forms.

You can learn more about this version in our blog post.

For maintainers, a quick note, WeasyPrint now relies on tinyhtml5 instead of html5lib.

[FelixSchwarz]

I'm grateful for to the financial contributors but also of course kudos to the developers. I'll try to get tinyhtml5 into Fedora soon.

Just a quick question: Are there known incompatibilities with v62 and Python 3.13? I think the test suite did pass on in our Fedora builds.

[grewn0uille]

@FelixSchwarz 💜

There are no known incompatibilities between v62 and Python 3.13!
