#! /bin/bash
#
# This command runs the Uno hot reload server, downloading and
# building it if necessary.
#
# The server requires that you specify an HTTP port on which to
# run, via the --httpPort=<port> argument. Once it's running, you
# can build and run your Uno project (such as Skia GTK) with:
#
# $ dotnet build -property:UnoRemoteControlPort=<port> && dotnet run --no-build
#
# Once it's running, the hot reload functionality should work as normal.
#
# Note: at time of writing, the server requires .NET Core 3.1, even though Uno
# supports up to .NET 5. If you're using the `asdf` SDK manager with the .NET
# Core plugin, you should be able to ensure you're using the correct version
# with:
#
# $ asdf shell dotnet-core 3.1.401 # make sure it's installed
# $ source ~/.asdf/plugins/dotnet-core/set-dotnet-home.bash
# $ uno-hot-reload --httpPort=<port>
#
