    hi,

    I am trying to run an instance of IBEX locally to use in a computer in the lab with no internet access. It works fine for regular ibex experiments, but since the penncontroller requires access to an online server to load images and audio (when calling “PennController.AddHost”) I am not sure how to get it to do this locally. How can i get it to check a local folder on the computer instead of an online server?
    thanks a lot for the help (and for penncontroller in general, its awesome 🙂 )

    Hi Camilo,

    Are you running you IBEX instance on Mac OS? If so, you can place your image and audio files in /Library/WebServer/Documents/ (or ~/Sites/) and then access it at, e.g. http://localhost/myImage.png. So this should work:

    PennController.AddHost("http://localhost/");
    PennController(
        newImage("my image", "myImage.png")
            .print()
        ,
        newButton("continue", "Continue")
            .print()
            .wait()
    )

    Alternatively you can edit the file server.py in your experiment’s www folder and, below these two lines:

    if fname.endswith(".wav") or fname.endswith(".mp3") or fname.endswith("m4a"):
        continue

    add

    if fname.endswith(".png") or fname.endswith(".jpg") or fname.endswith(".bmp"):
        continue

    And further down, replace this line:
    start_response('200 OK', [('Content-Type', 'audio/mpeg'), ('Content-Length', stats.st_size)])
    with

    if qs_hash['resource'][0].endswith(".wav")  or qs_hash['resource'][0].endswith(".mp3") or qs_hash['resource'][0].endswith(".m4a"):
        start_response('200 OK', [('Content-Type', 'audio/mpeg'), ('Content-Length', stats.st_size)])
    elif qs_hash['resource'][0].endswith(".png") or qs_hash['resource'][0].endswith(".jpg") or qs_hash['resource'][0].endswith(".bmp"):
        start_response('200 OK', [('Content-Type', 'image/*'), ('Content-Length', stats.st_size)])

    Then you can place your image and audio files (though no OGG file) in chunk_includes and do this:

    PennController(
        newImage("my image", "http://localhost:3000/server.py?resource=myImage.png")
            .print()
        ,
        newButton("continue", "Continue")
            .print()
            .wait()
    )

    Hi Jeremy,

    wow, thanks so much for the detailed response! Unfortunately neither of these solutions worked for me. The first one (for mac) keeps spitting out this error in the terminal running the server.py:

    127.0.0.1 - - [26/Mar/2019 16:35:10] "GET /picture.jpg HTTP/1.1" 404 -

    I don’t know what it means, but it seems to not be able to connect to the local server (I saved all the pictures to /Library/WebServer/Documents/)

    The experiment runs fine otherwise and goes through all items, it just doesnt show any of the pictures.

    The second solution, working on a windows, seems to be even trickier, since the experiment doesn’t run at all, it gets stuck trying to load the images. the output of server.py shows a lot of stuff that I (again) have no idea what it means:

    I really have no idea how to make this work, any help would be immensly appreciated!

    Hi Camilo,

    1. Have you tried placing your images in ~/Sites/ as well?

    2. The errors could be due to hidden files in chunk_includes. On Mac, Finder automatically generates .DS_Store in some folders, which usually causes Ibex to crash. I usually solve the problem in the Terminal, I move to the chunk_includes folder and I type rm .DS_Store.

    This is an archive of the experiment I successfully ran on my Mac, if you want to try it yourself (and/or copy the server.py file in case you have doubts on the edits I describe in my previous message):

    Basically what is needed is are a webserver, that serves static files (jpg, mp3, etc), to be installed locally on your machine. There are many way to do that. Using Python httpserver is a portable and quick way, which is possible on any OS with python installed. For windows there is an instruction here: https://stackoverflow.com/a/5128451. See also other answers.

    That approach may seem dirty (but it should work!). More elegantly, Ibex server seems to use SimpleHttpserver already, so it is possible to configure it to serves static files from a folder in ibex folder structure (e.g., using relative path). This however requires some programming skill.
