Get working on Windows about reanimate HOT 19 CLOSED

Actually, it seems that I was a bit hasty in my last try. It turns out that if you wait a bit longer and ignore the errors, the Playground works just fine, including the live code update. There's still lots of errors though; it would be nice to get rid of them. There's also still the problem of the unix dependency which prevents Windows compilation; is there any reason why that cannot be removed?

Well, I've done a bit of digging, and it looks like most of the 'errors' above were just normal messages which I misinterpreted as errors. (Suggestion: rephrase these messages to make this more obvious so other people don't make that same mistake.) However, there are some genuine problems on Windows:

• Unused unix dependency prevents Windows compilation. Fix: remove dependency, since it doesn't appear to be doing anything.
• Browser isn't opening on Windows. Fix: use the open-browser package, or add "start" (the Windows command) to Reanimate.Driver.openBrowser.
• Weird errors with DeleteFile and runInteractiveProcess (see above for exact error messages). Fix: I'm really not sure, actually. I think it's a problem with a dependency (possibly fsnotify), not with reanimate itself.

Since #2 has been merged the HEAD of reanimate now compiles and works on Windows. However, the weird file errors are still there, so I won't close this issue just yet.

Do you know why the errors happen? Is it something we can test for?

from reanimate.

For me, it happens when I reload the browser window but not when changes are detected via fsnotify. No idea why this is so, though.

Hi @bradrn. I've fixed a few race conditions in the driver and now everything works smoothly for me on Windows. If it also works for you then I'd like to close this issue.

Hi @lemmih, thanks so much for fixing this! Unfortunately I don’t have enough time just right now to test it, but in a few hours when I get home I will definitely try it out.

from reanimate.

Sigh, I spoke too early. I still see the same errors.

from reanimate.

Ok, now I've fixed the last issues (I think). Everything works as well on Windows as it does on Linux for me. Code reloads, refreshing the browser, latex output, etc.

Sounds good @lemmih! I finally have enough time to test this (it’s compiling as I write), so will inform you if it works for me.

Out of curiosity, in which commits did you fix the issue?

Reusing the same temporary directory for compilations messed things up for some reason. Using a separate directory for each compilation fixed the errors for me.

from reanimate.

That’s odd. Do you have any idea why reusing the same directory would have caused those issues?

from reanimate.

Nope, it wasn't a problem on Linux or Mac. And it's particularly weird that GHC would create an empty binary but not give any error message or error return value.

I’ve just tried the latest version and can confirm that the DeleteFile and runInteractiveProcess errors are gone! However, I still get terminateProcess: permission denied (Permission denied) errors, even when I run as administrator.

from reanimate.

That last error is harmless. I think it happens because it tries to terminate a process which has already been terminated.

That last error is harmless.

I know, but it’s not too good an impression if you’re trying out this library for the first time…

It’s possible. I think it happens when I close a tab, but I will have to investigate more before saying anything definitively.

from reanimate.

Well, I can’t reproduce that error again. I still have no idea what caused it.

from reanimate.

Everything looks to be solved. Closing issue.

from reanimate.

That’s fine @lemmih.
