Notepad++ syntax highlighting for Dockerfiles (Dark version)

Store userDefineLang_DockerfileDark.xml at %AppData%\Roaming\Notepad++\userDefineLangs\userDefineLang_DockerfileDark.xml and select Language > Dockerfile in Notepad++.

This color theme is specifically compatible with VS2015-Dark-Npp Theme.

Automatically apply style

Since Dockerfile has no extension, the style is not automatically applied.

A workaround is to use the Plugin PythonScript.

Once installed, select Plugins > Python script > Configuration and change Initialisation from LAZY to ATSTARTUP.

Create a new script: Plugins > Python script > New Script, copy the code below and save as Dockerfile.py:

def callback_BUFFERACTIVATED(args):
    if 'Dockerfile' in notepad.getBufferFilename(args['bufferID']):
        notepad.runMenuCommand('Language', 'Dockerfile')

notepad.clearCallbacks([NOTIFICATION.BUFFERACTIVATED ])
notepad.callback(callback_BUFFERACTIVATED, [NOTIFICATION.BUFFERACTIVATED ])

Once you switch tabs, the style will be automatically applied to all tabs with the name Dockerfile. Currently, this does however not work on file open - if you find a solution, please add a comment.
