# import

## Name

*import* - include files or reference snippets from a Corefile.

## Description

The *import* plugin can be used to incude files into the main configuration. Another use it to
reference predefined snippets. Both can help to avoid some duplication.

This is a unique directive in that *import* can appear outside of a server block. In other words, it
can appear at the top of a Corefile where an address would normally be.

## Syntax

~~~
import PATTERN
~~~

*   **PATTERN** is the file, glob pattern (`*`) or snippet to include. Its contents will replace
    this line, as if that file's contents appeared here to begin with.

## Files

You can use *import* to include a file or files. This file's location is relative to the
Corefile's location. It is an error if a specific file cannot be found, but an empty glob pattern is
not an error.

## Snippets

You can define snippets to be reused later in your Corefile by defining a block with a single-token
label surrounded by parentheses:

~~~ corefile
(mysnippet) {
	...
}
~~~

Then you can invoke the snippet with *import*:

~~~
import mysnippet
~~~

## Examples

Import a shared configuration:

~~~
. {
   import config/common.conf
}
~~~

Where `config/common.conf` contains:

~~~
prometheus
errors
log
~~~

This imports files found in the zones directory:

~~~
import ../zones/*
~~~
