This lexer is pretty basic. It is inspired from an existing lexer found in Chroma.

The test seems too simple now as it does not contain any comment nor section ([Service], [Unit]…)

👌 limits the list of supported file extension

Only `.service` file extension would be supported for now

Never mind, this test is not the visual one. It does not really matter if the sample file is not complete.

@jljouannic Thanks for this! I'm about to start the release process for v3.23.0. Once that's complete, this will be part of the gem available from RubyGems. Thanks for helping to improve Rouge!

Why not use INI / dosini directly? As per the systemd syntax, it's almost compatible with INI.

Here's my blog post which uses dosini for systemd unit files. As can be seen, it renders perfectly.

(source code plus Wayback Machine in case my blog disappears later)

This is a first basic implementation, which, I agree, gives a pretty similar result as the INI lexer.
However, in the near future I plan to improve this systemd lexer by adding support for systemd specifiers.

Add systemd lexer (rouge-ruby#1568)
3f2a70d 
This commit adds a lexer for systemd unit files. These unit files can
have multiple extensions but this commit only supports the `*.service`
file glob at this stage.
