lambdasoup VS pyppeteer

OCaml’s Lambda Soup (https://aantron.github.io/lambdasoup/) is a amazing library/, especially for those that prefer functional programming

It's used for sorting "widgets" (page processing steps) according to dependency lists that users can specify in the config (like `after = ["foo", "bar"]`).

Other than that, one thing I really like about OCaml is that the compiler team and most library maintainers are considerate towards downstream users with respect to compatibility.

The Lua interpreter [3] that soupault uses for its plugin API is a revived 20 year old research project. It only needed minor modifications to build with recent compiler versions.

The normal Puppeteer package is JavaScript, but I do see that there's a Python port called pyppeteer. I can't vouch for it specifically, but I imagine it's similarly easy to use as the JS version.

If you're talking about CSS I reckon you want to click/input things on a website inside your browser. In this case you would use a web driver which can automate a web browser like Chrome or Firefox. Something like Helium, Selenium or pyppeteer.

In my own experience puppeteer is much better/capable than selenium but the problem is that puppeteer requires nodejs. its python-wrapper https://github.com/pyppeteer/pyppeteer was not as good as selenium when you like to use python.

Pyppetteer is feature complete and worth noting: https://github.com/pyppeteer/pyppeteer

For complex pages I usually use Puppeteer (from Google). A Python port is here: https://github.com/pyppeteer/pyppeteer but that's not widely used as the official JavaScript Version.

using headless browser or browser automation frameworks, such as * selenium or pyppeteer.

If JavaScript is involved then things get ugly quickly. The best approach usually is a headless browser. There are several options, pyppeteer is the one I currently use.
