First solution : port the patch of bug 446591 into XulRunner (so we need to compile and provide our own XulRunner). It will be a huge work.

Second solution: since Gecko 23, it seems there is a new method nsIAppShellService::createWindowlessBrowser(). We should investigate if we could use this method to load our webpages.

Webdriver is a library to support the Selenium protocol. We should include it and support these cli options:

--webdriver or --wd or -w
--webdriver=ip:port
--webdriver-logfile=/path/to/logfile --webdriver-loglevel=[ERROR|WARN|INFO|DEBUG] --webdriver-selenium-grid-hub=url

Hi, some issues while testing slimerjs on centos 6 linux:

1. the page https://github.com/laurentj/slimerjs/blob/master/API_COMPAT.md says that zoomFactor is implemented but i tried it and doesn't seem to work. Scaling doesn't happen. Is the use of zoomFactor different than in PhantomJS?

Im currently using this code to test:

and my script is var page = require('webpage').create(); page.open("http://volandino.com/fonts/fonts.html", function (status) { // page.viewportSize = { width:1920, height:1080 }; page.viewportSize = { width:9600, height:5400 }; page.zoomFactor = 5;
page.render('screenshot2.png') });

2. I launched a screen with this command Xvfb :99 -ac -screen 0 1024x768x16

and then When executing slimerJS it always Hangs, something with the xvfb server maybe, if i do it from php it doesnt work or produce anything, it just hangs, if i execute it from Command line Shell then it generates the PNG image well but it also hangs and i have to stop it with CTRL-C , do you know how to make it work without Hanging and also how to make it work from php ?

it only generates image from command line shell, and it hangs both from command line and from php

finally one more thing, the render of webFonts is perfect on png, very happy, but there is slight color fringing in some letters and also edges of letters are not as smooth as in phantomjs i feel, any opinions about that? Howeves shapes of webfonts come out perfect (unlike in phantomjs) which is so so so important, very happy with that

thank you very much for your help Jav

Freeciv-web uses CasperJS with SlimerJS to provide testing of JavaScript functionality. However, recently the following error message has prevented the CasperJS tests completing correctly:

"Gecko error: it seems /usr/bin/firefox is not compatible with SlimerJS. See Gecko version compatibility."

The error message can be seen in the TravisCI build logs here: https://travis-ci.org/freeciv/freeciv-web This is the script which installs SlimerJS and CasperJS, then runs the test-cases: https://github.com/freeciv/freeciv-web/blob/master/scripts/freeciv-web-travis.sh

TravisCI has Firefox version firefox 31.0esr. It has also been tested with Firefox 38.0.5 on a local Linux distribution.

We use SlimerJS master from github. On 25 April, SlimerJS master version from github worked correctly. However, the current SlimerJS master version does not work, and gives the error message about "Gecko error" given above. Slimerjs-0.10.0pre has the same problem. I have also tested version 0.9.5, but that didn't work.

So which version of Slimerjs, Firefox and CasperJS can I use to get JavaScript testing on TravisCI?

as i described here : http://stackoverflow.com/questions/26386415/phantomjs-and-slimerjs-fail-to-render-some-sites I get no image file after executing render_multi_url.js on some website I don't know the cause. can any one investigate on this . thanks

Most of this has been lifted/augmented from the existing slimer package, special thanks to @graingert for maintaining the slimerjs npm package for so long.

It's not quite perfect yet, but it should be landable in its current form. If it looks good to @graingert and @laurentj I think it would be good to land this and continue to iterate. This will allow many more JS developers to leverage SlimerJS easily in their projects.

Hi, I am working on one project that require to render HTML5 Animation into video file. I was using PhantomJs to directly pipe the object using /dev/stdout to FFmpeg using image2pipe and I can get it worked. The problem with the latest version of PhantomJs is, it doesn't render all the HTML5 Animation elements. Some elements are missing from the video output.

Is it possible to do the same thing with SlimmerJS? I 've tried to google the issue but I got no luck for finding the best answer.

So, it could be something like:

page.render('/dev/stdout', { format: 'png', quality: '90' });

and the complete command when executing via terminal is something like:

xvfb-run ./slimerjs html5.js | ffmpeg -y -c:v png -f image2pipe -r 25 -t 10 -i - -c:v libx264 -vf "crop=640:360:0:0" -pix_fmt yuv420p -movflags +faststart VIDEO.mp4 2>Test/LOG.log

Here's my complete js file that executed by SlimmerJS:

var webPage = require('webpage');
var page = webPage.create();

page.viewportSize = { width: 640, height: 360 };
page.open("URL_TO_HTML5_ANIMATION", function start(status) {
    function waitit(){
        var checkComp = page.evaluate(function(){
            return compready();
        });
        if(!checkComp){
            setTimeout(waitit, 500);
        }else{
            page.evaluate(function(){
                controls(false);
            });

            var duration = page.evaluate(function(){
                return getduration();
            });

            var frames = (duration * 25) / 1000;

            for (var i = 1; i <= frames; i++) {
                page.evaluate(function(){
                    nextframe();
                });
                page.render('/dev/stdout', { format: 'png', quality: '90' });
            };

            slimer.exit();
        }
    }
    waitit();
});

I got empty result with this message comes from FFmpeg:

After using npm to install the latest slimerjs, the binary doesn't seem to be functional.

$ sudo npm -g update slimerjs

/usr/local/bin/slimerjs -> /usr/local/lib/node_modules/slimerjs/bin/slimerjs

> [email protected] install /usr/local/lib/node_modules/slimerjs

Looks like an `npm install -g`; unable to check for already installed version.

hi :) im not sure why this is happening, but if i set a web font to italic and/or bold, if i render it with phantomjs it renders great, if i try to render it with slimerjs, the italic/bold setting is not applied

here is the demo: http://volandino.com/subscriptions/bug-fontitalicbold.php

use buttons below to capture with both phantom and slimer

thing is, in my app i need to apply italic/bold, so im surprised that slimerjs is not capturing the italic/bold setting, any tips?

thank you http://volandino.com/subscriptions/bug-fontitalicbold.php

So please, download SlimerJS 0.10pre, and test it with your Selenium installation. And open new issues if you have some problem, by explaining how to reproduce it. Thank you :)

Anyone successfully interface the experimental SlimerJS 0.10pre with Selenium in Python? I'm really excited about the new webdriver feature. If you can get me up and running and the functionality is there, I'll be happy to contribute more.

I started with this simple Python script:

from selenium import webdriver
+other selenium includes not used in this example

driver = webdriver.PhantomJS(executable_path="./slimerjs", service_args=['--webdriver=127.0.0.1:53598'])
#driver = webdriver.Firefox(executable_path="./slimerjs --webdriver=127.0.0.1:53598")
driver.set_window_size(1280,1024)
driver.get('https://slimerjs.org')
driver.save_screenshot('screenie.png')

With driver = webdriver.PhantomJS(executable_path="./slimerjs", service_args=['--webdriver=127.0.0.1:53598']) Firefox opens and displays 'SlimmerJS' but then errors out giving me:

Traceback (most recent call last):
  File "skinny.py", line 10, in <module>
    driver = webdriver.PhantomJS(executable_path="./slimerjs", service_args=['--webdriver=127.0.0.1:53598'])
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/phantomjs/webdriver.py", line 51, in __init__
    self.service.start()
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/phantomjs/service.py", line 83, in start
    "Can not connect to GhostDriver on port {}".format(self.port))
selenium.common.exceptions.WebDriverException: Message: Can not connect to GhostDriver on port 54658

The listed port it claims to not be able to connect to is different every time and doesn't match the command line port parameter.

With driver = webdriver.Firefox(executable_path="./slimerjs --webdriver=127.0.0.1:53598") Firefox opens, but not headlessly. It functions just as if slimerjs wasn't there.

Any idea how I should configure this simple Selenium script in Python?

I can't seem to open any website when using a SOCKS5 proxy with username:password auth. I know Firefox doesn't support it, but you guys don't mention such limitation on your docs, that I've seen at least.

There are small typos in:

• docs/faq.rst
• docs/manual/addons.rst
• src/modules/addon-sdk/toolkit/loader.js
• src/modules/slimer-sdk/net-log.js
• test/jasmine/jasmine.js

Fixes:

• Should read quotes rather than quots.
• Should read implementation rather than implemenatation.
• Should read functionalities rather than functionnalities.
• Should read extremum rather than extrem.
• Should read combination rather than cominbination.
• Should read channel rather than chanel.

Steps to reproduce the issue

Generating dynamic snapshot with following command: xvfb-run -a /plugins/slimerjs/slimerjs /plugins/slimerjs/createThumbnail.js Test-Image.png 1280px*720px 1500 debug=true Note: Snapshot generation is working fine with Images. It's failing only for video assets.

Actual results:

Dynamic thumbnail generation is not proper for video assets, blank screen/ video player loading Icon is coming in the dynamic screenshot screen Error log: [DEBUG] network: resource #55 response in error (3): 99 - an unknown network-related error was detected (NS_ERROR_UNEXPECTED)

Expected results:

Dynamic snapshot should contains actual video poster Image.

Hi all,

Mozilla has removed support of XUL extensions into Firefox few years ago. It means that many of some internal API of Firefox were no more stable. So they have been changed or deleted, replaced etc... MarkR2 explained well the situation in his comment.

So it became more an more difficult to maintain Slimerjs, and probably impossible to update the Slimerjs code for the latest Firefox. And I don't have time anymore to work on Slimerjs.

Consider Slimerjs as a dead project.

Of course, SlimerJS 1.0 is still working with Firefox 59 (that you can download from here), but, obviously, it won't work very well with web sites that are using latest Web Standards that are not supported by Firefox 59.

Thank you very much to all contributors and users.

versions

• SlimerJS: last
• Firefox: 59
• Operating system: ubuntu

I need each script to connect to a different proxy server in each instance of firefox. How can this be done ?

When I start my script I connect to the proxy that I have configured in ubuntu, how could it be customized?

versions

• SlimerJS: 0.10.0
• Firefox: 67
• Operating system: Windows Server 2016 Datacenter

Steps to reproduce the issue

Launch the Slimer Server from windows cmd line as below:

C:\slimerjs-1.0.0>slimerjs.bat slimer.js

versions

• SlimerJS: 1.0.0
• Firefox: 59.x
• Operating system: Ubuntu 18.04

Steps to reproduce the issue

Heroku CLI provides a method to run one-off containers in detached/non-interactive mode (heroku run:detached). I use this command to wget a remote bash script and execute it. In the script, I have these lines:

#!/usr/bin/env bash

set -x

echo "Starting..."
slimerjs --headless /tmp/script.js
echo "Finishing..."

# now calling webhook to notify other end
curl -v -d 'done=xyz' https://webhook.example.com 

However the process exits with 0 and the lines after slimerjs never work. It's weird that when running in interactive mode (full TTY), the script works as expected.
