Pagedown: Add support for Edge with Chromium in find_chrome

[cderv]

As discussed with @RLesur, New Edge browser is [officially out and it is based on Chromium now, offering the Chrome Devtools Protocol - same one as in Chrome or Chromium headless.

Here are some ressources on this new version:

• Edge Devtools on Chromium
• Edge Devtools Protocol same as Chrome Devtools protocol
• puppeteer can be used

I tested that it works with crrri, our R 📦 for interfacing with chrome devtools protocol in browser.

Then I tested with pagedown::chrome_print and it works perfectly find just by changing the binary

Sys.setenv(PAGEDOWN_CHROME = "C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe")
pagedown::chrome_print("https://pagedown.rbind.io/", output = "pagedown.pdf")

First good news: pagedown::chrome_print works find with new Edge ! 🎉

For all those who can't have access to chrome or chromium on their computer, but have Edge in the newer version, it could be nice to support Edge browser in find_chrome or at least mention in the doc it works with Edge Chromium.

The logic could be:

• Find chrome on windows
• If not found find Edge and check the version to see if it supports chromium

🤷‍♂ Or there could be a pagedown::edge_print with a find_edge ? 😉 😄

Hi @cderv,

We can also add the Brave browser to the list of browser we can support, it's also based on Chromium.
Thanks

Thanks @dickoa .
Did you try to print a pdf using chrome_print with this browser ? Does it work out of the box ?

[dickoa]

I tried this command on Linux and it worked perfectly

Sys.setenv(PAGEDOWN_CHROME = "/usr/bin/brave")
pagedown::chrome_print("https://pagedown.rbind.io/", output = "pagedown.pdf")

I just hope that it didn't use my Chromium install I also have on my machine.

Is someone interested in sending a PR?

[cderv]
