require
Type
command
Summary
Executes the given script in the context of the global environment.
Syntax
require <script>
Description
Executes the given script in the context of the global environment, but only if it has not previously been included or required.
This is the same as the include command in operation, except it makes it easy to implement 'include-once' files and is designed primarily for library scripts.
Scripts are parsed in full before being executed, with any handler and variable definitions being added to the home stack environment before any commands placed at global scope are executed. These are ordered by encounter in the file. As require is a command, the parse-before-execute effect only extends as far as the end of the current file.
include and require are distinct in the sense that if you require a file and then include, the second include executes the file.
