Local Scoping

About Variables

In osl all variables are global scope and to use locally scoped variables you must use the keyword local

Where can I use local?

You can local scope inside of any function context

How does local work?

The local keyword creates a key on an json object that's unique to the current context/scope that's accessible using the this keyword

local key = "1234"

log this
// returns {"key":"1234"}

this has a different value depending on the scope of when you access it

Example script

def "test_cmd" (
  local hello = "greetings!"
  log hello
  // logs "greetings!"
)

local hello = "hello world"

test_cmd

log hello
// logs "hello world"

If a local variable and a global variable exist with the same name, it will access the local variable first.
