Problems with Blink.jl

[srgk26]

Hi! Thanks for this great package first of all. But I'm having problems in opening the app.

I'm building a stats plotting GUI app, whose executable also automatically installs required softwares and packages, attempting to use the user's packages for the app instead of bundled libraries and resources from within the app. Partly because I'm having too many problems in identifying and changing the relative paths of all the libraries and dependencies to relative paths. I'm aware you're working on this issue too, I saw your PR. But for now, I'm keeping the app simple.

The problem is, when I click the app icon, it opens the Blink window momentarily and closes, regardless if the libraries and dependencies are bundled within the app. This might be relevant to #JuliaGizmos/Blink.jl#195.

As per the suggestion, I added readline()to the back of the code. It then works when I execute the script by $ exec julia test.jl. It also works when I open the executable from within the test.app/Contents/MacOS folder. But it doesn't work when I click the test.app icon.

Here is the full code and command line commands to build the app:

Command line:

$ exec julia /Users/srgk26/.julia/packages/ApplicationBuilder/cTrYQ/build_app.jl --bundle-identifier "com.srgk26.test" --app-version=0.1 --certificate "Developer ID Application: srgk26, LLC" ~/test.jl  "test" ~/builddir/

test.jl file:

using Blink

Base.@ccallable function julia_main(args::Vector{String})::Cint
    Blink.port[] = get(ENV, "BLINK_PORT", rand(2_000:10_000))

    sleep(2)
    w = Window()
    body!(w, "Hello, world!")
    readline()  ## To keep Julia process active

    return 0
end

Also, if you have some spare time, I also did try to bundle the resources together and change the paths to relative paths like your Blink.jl example. This is the error message:

It raised that it couldn't find Electron. But I do have electron browser installed and is working fine when I run it locally. I also tried to install the Electron app manually and keep the name Electron.app. But it was still raising errors.

This was my command line command:

$ exec julia /Users/srgk26/.julia/packages/ApplicationBuilder/cTrYQ/build_app.jl \
-R /Users/srgk26/.julia/packages/Blink/6QR5U/deps/Julia.app/ \

I would appreciate if you/anyone could help. Thanks!
