Is there a way to display a Ruby hash as a JS object without quotes for certain values in the hash, essentially as JS code? For instance, consider the following Ruby code:
{ foo: proc { 'someJavascriptFn()' } }.to_json
How can I have the JS output as:
{ foo: someJavascriptFn() }
Is it possible to achieve this without making modifications to proc or hash?
Achieving this is possible, however, the creation of JSON will need to be done manually:
hash = {
foo: proc { 'someJavascriptFn()' },
bar: 42,
baz: "Hello, world!"
}
content = hash.each_with_object([]) do |(k, v), acc|
acc << ("#{k}: " << (Proc === v ? v.() : v.inspect))
end.join(",\n")
#⇒ "foo: someJavascriptFn(),\nbar: 42,\nbaz: \"Hello, world!\""
puts "{#{content}}"
#⇒ {foo: someJavascriptFn(),
# bar: 42,
# baz: "Hello, world!"}
Keep in mind that if your input contains nested structures, you may need to implement a recursive call to handle them.
