systemd-language-server

Language server for systemd unit files. Result of an exercise to learn the language server protocol.

Supported Features

textDocument/completion

Completion for

• unit file directives
• unit file sections

textDocument/hover

For markup in hover windows (i.e. the fancy highlighting), pandoc must be found in $PATH. Otherwise, there will be fallback to plain text.
