move to discussions: live JavaScript test, -nocolour option and other features

enable discussion in project settings

https://github.com/rkd77/elinks/discussions

enable discussions in project settings and move this thread there

todo

this and other css is missing

 .hidden {display: none}

this works unfortunately and don't expect a page reload despite omitting return false

<a href="#" onclick="abc()">

live test

live code test from the internet with my -test branch that enable page view and log all snippets

https://github.com/john-peterson/elinks/commits/test

to be used as

elinks test.html -test 2>log

or

export ELINKS_LOG=log
echo >log; elinks -test test.html

quickjs

https://linux.die.net/man/2/getuid

requires http >=2 and fake agent not JavaScript as the pre processor suggested

links $url -dump
Enable JavaScript and cookies to continue
curl $url -sSI --http1.1|head -1
HTTP/1.1 403 Forbidden
curl $url -sSI --http2|head -1
HTTP/2 403 
curl $url -sSI --http2 -A Gecko|head -1
HTTP/2 200 

~/.config/elinks/elinks.conf
set protocol.http.use_curl = 1
set protocol.http.user_agent = "Gecko"

https://www.flupe.com/code/javascript/02_matrix-swap/matrix_swap.html

works without issues

https://www.flupe.com/code/javascript/10_mapleton-hill/time-slider-widget.html

the anchor links reset the page and this breaks traditional buttons

<body onload="onLoad()">

<a id="up-button" href="#" onclick="timeSliderInstance.onUpButtonClick(); return true;">UP</a> - Add

[js quickjs.c 402 quickjs_eval]:
var timeSliderInstance = null;
    function onLoad() {

      // NOTE: 24 Hours equals 1,440 minutes...

[js quickjs.c 402 quickjs_eval]:
onLoad()...                               
[js quickjs.c 402 quickjs_eval]:
onLoad()...

[js quickjs.c 376 error_reporter]: ReferenceError: 'onLoad' is not defined
    at <eval> ()

https://bakkot.github.io/test262-web-runner/

local doesn't show any file selector. remote doesn't download the test

[js quickjs.c 376 error_reporter]: TypeError: cannot read property 'addEventListener' of undefined
    at <eval> (:757)

https://jsbenchmark.com

redirecting. nothing loads

https://jsbench.me/

no page content is loaded. -test show two quickjs_eval no errors

https://jsbin.com/usidix/1/edit?output

the text doesn't show up anywhere

https://www.w3schools.com/js/tryit.asp?filename=tryjs_intro_inner_html

the click me button is not on the page. parsing errors

[js quickjs.c 376 error_reporter]: TypeError: cannot read property 'document' of undefined
    at submitTryit (:20)
    at <eval> (:1)

mujs

similar results as above. i could not find any difference or improvement

mozjs

doesn't suppress repeat errors like qjs does

broken buttons can be tested repeatedly with repeated error alert

none of the broken pages worked here either

reddit

https://www.reddit.com/r/commandline/comments/ldnzk1/elinks_text_browser_is_back/

error related to new module type script

[12:37:51 js quickjs.c 376 error_reporter]: SyntaxError: unsupported keyword: export                                  at :2

it contains a placeholder for comments but no comments

Something went wrong. Wait a
        moment and try again.

refactor ecmascript -> js

short names are best

src/ecmascript -> src/js
test/ecmascript -> test/js

features

add -nocolor flag

it has no concept of background color the only solution is a -nocolor flag to disable colour codes completely . nice and easy

js engine in --version

print the js engine version not just the name

mouse wheel scrolling stop on input fields

this is plaguing all links derivatives. i need

flag that disable all input fields
a script that remove all input Fields

filter headers and footers

many pages have large headers before the page content

links -dump https://developer.android.com/reference/java/io/BufferedReader|wc
   7934   17223  319774

i need a script that removes the header from supported sites by finding a marker for the main content

termux build
