Earthly support

[zedtux]

Earthly is a kind of Makefile to build Dockerfiles so that you declare a file like this:

FROM ruby
WORKDIR /app

deps:
    RUN apt-update \
        apt-install --yes git

    SAVE IMAGE

docker:
    FROM +deps

    RUN git --version

    SAVE IMAGE docker:git

and using the earth command line tool, it will build the final image:

earth +docker

The example I'm giving make no sens but I wanted to keep it very simple.

Have a look at their Basics documentation for better examples.

Using this package in order to highlight a Earthfile is already well working but needs some improvements:

• Obviously, this package should support Earthfile in addition to Dockerfile.
• The targets (deps and docker in my example) should be coloured. I was thinking of a blue color.
• The Earthly specific commands, like SAVE IMAGE, SAVE ARTIFACT and so on needs to be coloured like RUN, COPY and so on.
• The FROM command is not coloured when having spaces in front of it and it should in a Earthfile

Please see here what I have right now:

This is being developed at a separate plugin in the end: https://github.com/earthly/earthly/issues/331. I believe this issue can be closed.
