Local Scoping

About Variables

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

Where can i use this?

You can use this inside of the following scopes

def

method

main

run

How does this work?

The this variable is a json object that can be modified by setting keys on it, as shown below

this.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"
  this.hello = "greetings!"
  log this.hello
  // logs "greetings!"
endef

this.hello = "hello world"

test_cmd

log this.hello
// logs "hello world"
