Good Morning!
Does anyone have any good recommendations for HTML to PDF utility for running on Debian (Trixie)?
This one: https://wkhtmltopdf.org/, is no longer active.
That's what I would have suggested. Didn't know it had become inactive:confused:
And... morning! The forecast is warming us of "snowmageddon" - 7-12" on Sunday. But at least we should be some way north of the ice storms...đŹ
@dharrigan - Is this to run headless and programatically or for your desktop / workstation setup?
headless, within a container, for generating PDFs from Hiccup (to HTML)
I'm currently using wkhtmltopdf, but looking around for similar supported tech
OK, I will go back and look at my notes, but to be transparent I have not had to solve this problem for a while, so I am going to assume that I am behind the curve. I am curious to see if anyone else who is more current comes up with interesting solutions / tech and even if not I am curious to see what you end up on, as this is something that comes around again and again in my life... đ
I have nothing more current than wkhtmltopdf to offer... I had a little Google sess; have you seen this:
https://apitemplate.io/blog/html-to-pdf-on-linux-best-commands-and-tools/
ignore the cloud service that they are selling, and just focus on the using Chromium in headless mode on the command line..?
I think that this is what I would do, FWIW, but clearly YMMV
There may be mileage in using Weasyprint, possibly via a Clojure / Python bridge...? if you don't want to use Python (could relate)
Thanks, will have a looksee đ
Morning All đ´ó §ó ˘ó łó Łó ´ó ż
In case anyone here is not in the #events channel...
As another experiment I'm trying out, I'm deploying customised JREs, built from running jdeps and jlink over the generated uberjars.
Oh, and another thing I'm doing atm is writing "modern" java, with all those vars, streaming and records đ
to try writing a little internal stress tester for websockets đ
@dharrigan Is your employer a Java shop then? Or is this "just for fun"?
Just for fun. I wanted to challenge myself to write modern java, given that it's been years since I wrote any java
Modern Java isn't bad. It's a huge improvement over legacy Java.
Totally agree, it's actually quite terse!
I used to code in Kotlin before Clojure, so it was interesting to see how Java has moved on
Ah, I quite like Kotlin but never did much more than learning the basics... and write this: https://github.com/seancorfield/boot-kotlinc
Hahaha... last update 2017-11-28... over eight years ago!
đ
I wrote this too: https://github.com/dharrigan/cotlin
haven't visited it in 5 years, no idea if it still works or not
(probably safe on the clojure side, not so sure about the kotlin side)
Yup:

Hello Clojure World! 25.0.1
Hello Kotlin World! 25.0.1
Good Boy Biscuit
Woof Woof!
HOW MUCH IS THAT DOGGY IN THE WINDOW?
nil(I added a println of java.version since initially it failed to build with JDK 26 EA)
w00t đ
We can check again in another 5 years đ
