bun.sh as runtime

[yagarea]

Hello, is there way to use bun.sh as runtime ?

Thanks for support

See #116

You can probably define an ExternalRuntime that call bun run https://github.com/rails/execjs/blob/master/lib/execjs/runtimes.rb#L21-L26

Thanks for suggestion. I tried this:

require 'execjs'
require "execjs/external_runtime"

PATH_TO_JS = File.join(__dir__, "/katex.min.js")
BUN = ExternalRuntime.new(
      name:        "Bun",
      command:     ["bun run"],
      #runner_path: ExecJS.root + "/support/node_runner.js",
      encoding:    'UTF-8'
)
KATEX = BUN.compile(open(PATH_TO_JS).read)

But I get

project.rb:10:in `<top (required)>': uninitialized constant ExternalRuntime (NameError)

Am I accessing the ExternalRuntime class right ?

ExecJS::ExternalRuntime.new

Thank you! You did great job.

Is there a way to force my program to select bun as runtime even I have nodejs and bun installed at the same time ?
