It is basically just a simple webdriver http client wrapped in some roc types.
(you need a running webdriver server - at least for now)
There is still a lot to implement (like rendering pdfs, and making screenshots from the browser, but first I need to find / write a base64 decoder)
Although, for me it is already fun to use :)
Keep in mind that this package is importing the basic-cli platform - which should not be possible and will be blocked by the compiler in the future.
Why? - I need to make Http calls to the webdriver...
So this package works right now, but will problably stop at some point.
The goal is to wait for the module params feature - then I will release a stable version of r2e.
Here is the repo: https://github.com/adomurad/r2e
And here is the documentation and tutorials: https://adomurad.github.io/r2e-docs/
this are just temporary docs - due to using the basic-cli platform I was not able to use roc docs
Here is an example on how to use the repl on roc-lang.org :
test2 = test "use roc repl" \browser ->
# go to roc-lang.org
browser |> Browser.navigateTo! "http://roc-lang.org"
# find repl input
replInput = browser |> Browser.findElement! (Css "#source-input")
# send keys to repl
replInput |> Element.sendKeys! "0.1+0.2{enter}"
# find repl output element
outputEl = browser |> Browser.findElement! (Css ".output")
# get output text
outputText = outputEl |> Element.getText!
# assert text - fail - it is actually 0.3 !!!
outputText |> Assert.shouldBe "0.3000000001 : Frac *"
