Live demo not working

[wtjones]

Doesn’t finish loading. iOS 11

I dont think its limited to iOS safari - it doesn't load for me on Firefox (62), macOS, either.

indeed. on OSX in chrome shows this:

developper window shows:

Clicking on "Live demo in WebGL" gives a 404 error now.

[timotheecour]

not anymore, maybe the recent fix to CI (that now passes) fixed the 404 error; the issue still remains though ;

/cc @yglukhov could you rename the issue titile with "Live demo not working" ? how could one run the demo not minified for debugging? the minimified js isn't very helpful:

To run the demo without the minifier, edit nakefile.nim and change disableClosureCompiler to true. But currently there's at least https://github.com/nim-lang/Nim/issues/9643 and https://github.com/nim-lang/Nim/issues/9644 which are the reasons. Maybe there's more...

[timotheecour]

hmm wondering whether --nilseqs:on vs --nilseqs:off would make these work ; if that's the case then at least we've narrowed down the problem happy to try if you tell me how to run the live web demo locally (I could also search for how to do that...)

[yglukhov]

hmm wondering whether

It will not work with --nilseqs:on because nimx code relies on the new non-nil-seqs semantics (

happy to try if you tell me how

To add nim flags, add the following to the nakefile:

beforeBuild = proc(b: Builder) =
    b.disableClosureCompiler = true
    b.additionalNimFlags.add "--nilseqs:on"

[timotheecour]

@yglukhov a root cause https://github.com/nim-lang/Nim/issues/9643 was just fixed, curious whether it helps for this issue

[yglukhov]

It works now with latest versions of everything.
