< p > Most configuration files offer an < code class = "language-plaintext highlighter-rouge" > includes< / code > directive that allows users to break up large configuration files into smaller and organized parts. For example, consider a system with many menus/screens. Instead of a single < code class = "language-plaintext highlighter-rouge" > menu.hjson< / code > , the SysOp may break this into < code class = "language-plaintext highlighter-rouge" > message-base.hjson< / code > , < code class = "language-plaintext highlighter-rouge" > file-base.hjson< / code > , etc.< / p >
< p > The < code class = "language-plaintext highlighter-rouge" > includes< / code > directive may be used the top-level scope of a configuration file:< / p >

< h3 id = "environment-variables" > Environment Variables< / h3 >
< p > Especially in a container environment such as < a href = "/enigma-bbs/installation/docker.html" > Docker< / a > , environment variable access in configuration files can become very handy. ENiGMA½ provides a flexible way to access variables using the < code class = "language-plaintext highlighter-rouge" > @environment< / code > directive. The most basic form of < code class = "language-plaintext highlighter-rouge" > @environment:VAR_NAME< / code > produces a string value. Additionally a < code class = "language-plaintext highlighter-rouge" > :type< / code > suffix can be supplied to coerece the value to a particular type. Variables pointing to a comma separated list can be turned to arrays using an additional < code class = "language-plaintext highlighter-rouge" > :array< / code > suffix.< / p >
< p > Below is a table of the various forms:< / p >
