PlutoSliderServer on Windows

[VivaldoMendes]

Hi,
I am trying to use PlutoSliderServer for the first time. I created a Julia environment that I called plutoserver, then I did add PlutoSliderServer. Apparently, the installation went smoothly. I tried the first example on the website, and I got the message:

julia> path_to_notebook = download("https://raw.githubusercontent.com/fonsp/Pluto.jl/v0.17.2/sample/Interactivity.jl")
"C:\\Users\\UTILIZ~1\\AppData\\Local\\Temp\\jl_49sv0d6TwR"

julia> PlutoSliderServer.run_notebook("C:\\Users\\UTILIZ~1\\AppData\\Local\\Temp\\jl_49sv0d6TwR")
ERROR: AssertionError: PlutoSliderServer does not work on Windows yet!

Is the error message correct, or am I doing something wrong?
Thanks

Hey @VivaldoMendes !

Unfortunately we still don't support Windows :( But we are definitely interested in a PR if you are interested in contributing! The problem is with path separators for static URLs: the URL localhost:2345/a/b/c.html is mapped to the local file a/b/c.html. On Windows, this should map to a\b\c.html, and we don't have code to handle this yet.

For an implementation, be sure to use URIs.jl and joinpath, not just string replacements.

Hi @fonsp, thanks for replying.

I have tested PlutoSliderServer on Linux (Ubuntu) as well. However, I kept doing something stupid. As far as I can understand, in Linux, the plutosliderserver seems to run OK and create the server, but then it spits out the following error:

error: Uncaught PermissionDenied: Permission denied (os error 13) about ["/tmp/systemd-private-ef8b2c2d7f1f40388db3325afb12e1dc-systemd-timesyncd.service-sNRh7g"]
    const watcher = Deno.watchFs("/tmp");
                         ^

    at Object.watchFs (deno:runtime/js/40_fs_events.js:64:12)
    at file:///home/violeta/$deno$eval.js:1:26

I would be more than glad to help, but I wonder if I can be of much help. I know some cases where PlutoSliderServer works very well, e.g., @jbrea 's course here.

If the sliderserver does not have write access to "/tmp" you could set the environment variable TEMP to some path it has write access to.

@VivaldoMendes thanks for the report! Can you create a new issue and post your complete terminal log? Also post the output of:

# see permissions of the `/tmp` folder
ls -lha / | grep tmp
# try creating a temp file
touch /tmp/asdf.txt

Hi @fonsp and @jbrea
I did as you suggested and I had no problem to create the text file in the TEMP folder. The permissions are here:

violeta@violeta-QOSMIO-X70-B:~$ ls -lha / | grep tmp
drwxrwxrwt  19 root root  20K Mar 31 16:36 tmp
violeta@violeta-QOSMIO-X70-B:~$ touch /tmp/asdf.txt

Still not sure what is preventing the server to be reached.

Thanks

I would love to take on Windows support, but could @fonsp point me to a starting point of where the URL <-> file path work is done? I started looking over the source code and couldn't find a starting point.

[fonsp]

Sorry for the late reply! You can search for all uses of relpath, relpath, dirname and / in PlutoSliderServer, that should find most cases where conversion is needed. You just need to replace(s, '/' -> '\\') and vice versa wherever needed.

Make a fork, start editing, and keep running the PlutoSliderServer tests until you found all issues 👍

@mrufsvold Are you currently working on this? I'm also keen to get this working, as I can't get github.com/JuliaPluto/website running on windows if PlutoSliderServer doesn't work on windows.

[mrufsvold]

Thanks for checking with me! No, I'm not on the work project that needed this, so it slipped off my radar. Take it away!

PlutoSliderServer 1.4.0 (currently being released) comes with experimental windows support! Try it out and let me know how it goes!
