04:13 🔗 DFJustin has joined #jsmess
04:16 🔗 SketchCow People have suggested I use Chrome headless. That will mostly stop the hellish console messages exploding out of firefox as I see them
04:17 🔗 SketchCow And I can always use the old trick I was using of ingesting the colors along one edge to determine where the screen is
04:18 🔗 SketchCow But otherwise the same.
04:18 🔗 SketchCow So we'll see if hitsthings sees something
04:21 🔗 bai nah, you can grab a png or jpg directly from the canvas
04:21 🔗 bai you don't need all that phantomjs mumbo jumbo at all
04:21 🔗 bai just canvas.toDataURI('image/png')
04:23 🔗 SketchCow Need help understanding.
04:24 🔗 SketchCow Like, right now I do an Imagemagick
04:24 🔗 SketchCow How do I yell that at Firefox
04:27 🔗 bai well, this would be for chrome headless. so what I do for my screenshotter is, I load a special screenshotter.html in my headless chrome, and that runs whatever normal stuff, in this case it would create the emulator and add canvas to the document, etc
04:28 🔗 bai then at any point, like on timers or whatever like you have it now, you can call var imgbase64 = canvas.toDataURL('image/png');
04:29 🔗 bai then the next question is what you do with the base64 image, from there you can either make the browser download it as a file, or you can send it directly to an API
04:30 🔗 SketchCow This sounds.... involved
04:31 🔗 bai sure. so's wht you're doing now :D
04:31 🔗 SketchCow You got me into the restaurant with "simple" and then here we are cooking the souffle ourselves
04:31 🔗 SketchCow It's all horrible
04:32 🔗 bai basically, extracting the image data is the easy part. it's the pipeline around that that's hard
04:32 🔗 SketchCow I can run post-processing on a bunch of grabbed images
04:32 🔗 bai you have a pipeline for one method but this is a bit different
04:32 🔗 SketchCow We're all going to die, aren't we
04:32 🔗 SketchCow you, me, a pile of malformed screenshots
04:32 🔗 bai oh, definitely
04:33 🔗 SketchCow It all comes down to who eats other first
04:33 🔗 * SketchCow gets fork
04:34 🔗 bai I mean I can basically give you a function that you could call which would dump a screenshot into the browser's download directory
04:34 🔗 bai and from there you could do whatever kind of things
04:35 🔗 SketchCow Well, let's at least ask why I couldn't make chromium-browser headless
04:36 🔗 bai not sure I understand the question
04:36 🔗 bai you can
04:37 🔗 SketchCow I tried chromium-browser --headless
04:37 🔗 SketchCow Was there other magic
04:37 🔗 bai well, it's a relatively new feature so I'm not quite clear on exactly which version you need to be running to use it
04:38 🔗 bai but I think from there, I think yes, either there's a little bit of magic needed to script it if you want to do a bunch of phantomjs-style puppeteering, or you can just fire it at a page which does what you want as a regular old javascript script
04:44 🔗 SketchCow chromium-browser --headless --remote-debugging-port=9222 https://chromium.org
04:44 🔗 SketchCow [18796:18796:0312/044314:ERROR:browser_main_loop.cc(261)] Gtk: cannot open display:
05:49 🔗 SketchCow Meanwhile: I am going through a pile of 1,000 floppy images to add them to a collection
05:52 🔗 SketchCow Oh, speaking of "Jason wastes time on insane scripts"
05:53 🔗 SketchCow I did prelim work on a terrible idea that I'll do anyway
06:07 🔗 Vito` I can spend a little time right now on trying phantomjs 2.5 if you'd like
07:03 🔗 Vito` looks like the macos beta is broken
07:03 🔗 Vito` I'll try on Windows in a bit
08:05 🔗 bai everything is broken forever
08:31 🔗 Vito` okay uh
08:31 🔗 Vito` I think phantomjs still sucks
08:31 🔗 Vito` I'm injecting ES5 and ES6 shims and it's still barfing on that React thing
08:32 🔗 Vito` best bet is to file a bug with the phantomjs folks
09:05 🔗 Vito` https://gist.github.com/vitorio/52cf78c6b28423994434d728ac0eb4f9
09:05 🔗 Vito` that's the modified pacman.js I was using, it still doesn't work
09:05 🔗 Vito` best bet is to file a bug with the phantomjs folks
11:22 🔗 SketchCow Oh PhantomJS, why do you suck
13:49 🔗 SketchCow WebAssembly now supported in Chrome
13:54 🔗 SketchCow What kind of machine do we want as the "official" machine for Emularity?
14:13 🔗 SketchCow I'm starting to really gear towards the idea of we just get an AWS instance and use that.
14:14 🔗 SketchCow Document it up, write scripts to maintain it, etc.
14:14 🔗 SketchCow Share credentials
15:51 🔗 db48x I think loading pages from archive.org to screenshot is making things too complicated
15:51 🔗 db48x just load the emularity scripts, and then run this:
15:51 🔗 db48x var emulator = new IALoader(document.querySelector("#canvas"),
15:51 🔗 db48x "Pitfall_Activision_1982");
15:51 🔗 db48x emulator.start({ waitAfterDownloading: false });
15:52 🔗 db48x where, of course, you put in any item name you want instead of Pitfall
15:53 🔗 db48x then you grab the image out of the canvas and save it to a file, as usual
19:34 🔗 Vito` hm
19:34 🔗 Vito` IA scripts do support embeds right
19:34 🔗 Vito` maybe that
19:34 🔗 Vito` let me try it real quick
19:48 🔗 bai well this works http://assets.metacade.com/emulators/win311-wasm.html
19:48 🔗 bai loads nice and quickly in chrome and ff
19:49 🔗 bai like damn near instantly, once the data's loaded
19:51 🔗 Vito` the IA embeds still include react and jquery and stuff
19:51 🔗 Vito` so they are still broken
19:55 🔗 bai runs noticably faster on mobile. too bad it isn't emulating touch events properly
19:55 🔗 bai if I could use netscape 1.0 on my phone I would be so happy
20:18 🔗 webmirc has joined #jsmess
20:20 🔗 webmirc has quit IRC (Client Quit)
20:31 🔗 Vito` db48x: I'm getting "failed to download IA item metadata"
20:32 🔗 Vito` ah
20:32 🔗 Vito` okay so db48x's idea might work maybe
20:33 🔗 Vito` but it'd require having those pages served up by an actual http server
20:33 🔗 Vito` phantomjs's local-to-remote parameters aren't enough
21:02 🔗 Vito` nor is specifying a base href
21:03 🔗 Vito` it redirects to IA properly then, but the screenshots say it failed to configure emulator
21:03 🔗 bai maybe you need to point it to the cors address directly if it's not running on ia's servers?
21:04 🔗 Vito` the emularity loader seems to be doing that for me
21:05 🔗 Vito` but I can't really tell
21:06 🔗 bai if you see any requests in the network tab for cors_get.php then we're cool
21:18 🔗 Vito` yeah
21:21 🔗 Vito` even loading the IA loader example page from a localhost server doesn't work
21:23 🔗 Vito` works fine in a browser
21:24 🔗 Vito` 2017-03-12T16:20:14 [DEBUG] Network - Redirecting to "http://ia801906.us.archive.org/cors_get.php?path=%2F7%2Fitems%2Femularity_engine_v1%2Fa2600.json"
21:24 🔗 Vito` that's where phantomjs stops
21:24 🔗 Vito` in a browser it loads a bin and a cfg after that
21:27 🔗 bai hmm, localhost server as in a real webserver you mean, right? as opposed to just loading from files?
21:27 🔗 bai there are extra security restrictions when loading from files
21:28 🔗 Vito` yeah I turned those off and set a base href to archive.org
21:28 🔗 Vito` but it doesn't matter, it's the same behavior as with a localhost webserver
21:29 🔗 Vito` it stops/breaks on that json file
21:31 🔗 Vito` hm
21:32 🔗 Vito` different URLs break differently
21:32 🔗 Vito` the Oregon trail is saying access denied
21:32 🔗 Vito` service unavailable
21:32 🔗 bai yeah, what response does it get for the json, and are there any errors abing not being able to access its content?
21:32 🔗 Vito` another msdos app is saying remote host closed the connection
21:33 🔗 Vito` is IA blocking phantom?
21:33 🔗 Vito` 2017-03-12T16:33:45 [DEBUG] Network - Resource request error: QNetworkReply::NetworkError(ServiceUnavailableError) ( "Error transferring http://cors.archive.org/cors/msdos_Oregon_Trail_Deluxe_The_1992 - server replied: Service Unavailable" ) URL: "http://cors.archive.org/cors/msdos_Oregon_Trail_Deluxe_The_1992"
21:34 🔗 Vito` 2017-03-12T16:29:41 [DEBUG] Network - Resource request error: QNetworkReply::NetworkError(RemoteHostClosedError) ( "Connection closed" ) URL: "http://ia801502.us.archive.org/cors_get.php?path=%2F7%2Fitems%2Fmsdos_shareware_fb_PCM350"
21:37 🔗 Vito` oh hm
21:37 🔗 Vito` both of those seem to be broken in the emularity loader in a browser also
21:38 🔗 Vito` looks like there might be multiple points of failure here
21:38 🔗 Vito` db48x: if you can provide HTML that provides a simple, working embed for all types of IA resources, I can try again
21:39 🔗 Vito` but right now it looks like either emularity or IA are breaking
21:39 🔗 Vito` not only phantomjs
21:40 🔗 bai hmm. do those games work if you load them up directly on IA?
21:41 🔗 bai maybe IA is having server issues, it happened to me the other night when I was trying to prep slides the night before my talk
21:49 🔗 Vito` yeah both load up fine directly from IA
