Unit File Support for systemd

Introduction

This plugin adds support for systemd unit files to IntelliJ.

Features

• Syntax highlighting for unit files.
• Auto-completion for:
  • Option names in a section
  • Boolean options
  • Octal options
  • Some other common options (e.g., KillMode=, Type=, Restart=)
  • Unit names in dependencies (e.g., WantedBy=, Requires)
• Inspections
  • Invalid value for argument.
  • Shell syntax detected in Exec___= call.
  • Unknown option in section (ignoring those starting with X-)
  • Missing required key
• Annotations
  • When the section name is invalid or used in the wrong file type
  • Whitespace after a line continuation \ character.
  • When a key has been deprecated.
• Built-in documentation for options or section name (available when hitting CTRL+Q or F1 on Mac)
• Templates for several unit types

Usage

To create a file simply right-click on a folder and New > File, and enter a file name ending any of:

• .automount
• .device
• .mount
• .path
• .service
• .slice
• .socket
• .swap
• .target
• .timer

The file should then be associated with this plugin and the above features should work.

NOTE: .scope units are not configured via unit configuration files and so we don't support them.

Installation

This plugin is avaliable to install at the JetBrains Plugin Repository.

Development Notes

Commit Format

This has adopted Conventional Commits format for commit messages, in theory anyway. The main effect is that certain tags will be excluded from the automatic changelog.

System Requirements

Java 17

Manual Installation

Simply clone the repository, and run

./gradlew buildPlugin 

Then in IntelliJ navigate to

Plugins > Install Plugins From Disk > build/distributions/systemdUnitFilePlugin-X.X-SNAPSHOT.zip

Problems

Weird Fonts In Linux

When starting the development IDE if the fonts are poor add the following ENVIRONMENT VARIABLE to the run configuration

_JAVA_OPTIONS=-Dawt.useSystemAAFontSettings\=lcd -Dsun.java2d.renderer\=sun.java2d.marlin.MarlinRenderingEngine

Note: If you are using the Gradle runIde task it must be passed as an environment variable and not a VM option, because it gets executed in a different VM.

SLF4J Errors when running tests

If you see errors related to duplicate SLF4J class bindings available switch the JRE in use from the Default which references IntelliJ, to a native one.
