Opening this as a point of discussion For the vscode extension, I'd like to download/update to the latest released version (with a user prompt). For this, I need to know the currently installed version. Having a CLI --version allows me to query that It also provides a central configuration entrypoint for current and future options

If you think this is a good idea, I can then set up CI to create releases on tags and publish executables (with goreleaser) and the release process can be configured to pass the correct ldflags

It's not published or anything, and it has to be passed explicitely to vscode as cmd line option But it works, so I figured I'd push it as an initial version upon which we can build

Executing the downloaded binary from the release page crashes.

$ cd $(mktemp -d)
$ curl -O https://github.com/jdbaldry/jsonnet-language-server/releases/download/v0.3.0/jsonnet-language-server

$ chmod +x jsonnet-language-server 
$ ./jsonnet-language-server 
./jsonnet-language-server: 1: Syntax error: redirection unexpected

Whereas the go install works as expected:

$ go install github.com/jdbaldry/[email protected]
go: downloading github.com/jdbaldry/jsonnet-language-server v0.3.0
go: downloading github.com/hexops/gotextdiff v1.0.3
$ $HOME/go/bin/jsonnet-language-server 
2021/11/24 22:27:58 Starting the language server
2021/11/24 22:27:58 Using the following jpaths: []
^C

I'm guessing it works in Emacs, but with the typo, definitions were completely broken for vscode All good now!

Otherwise, vscode will jump to the end of the file every time the user saves

Uses https://github.com/hexops/gotextdiff/ which in turn just copies the code used by the golang LSP: https://github.com/golang/tools/tree/master/internal/lsp/diff

Closes #15

Adds (and improves) the language configuration from https://github.com/liamdawson/vscode-jsonnet-language (which took it from https://github.com/heptio/vscode-jsonnet) This makes this vscode plugin fully support the jsonnet language without any dependencies

I want to make this releasable in vscode ASAP so I can start testing iteratively (in real cases, not a development instance). With formatting and the navigation it currently has, it's already much better than the alternatives

Next steps:

1. Make the vscode extension download the latest language server release automatically
2. Release the jsonnet language server in a Github Actions upon tagging
3. Release and publish the vscode plugin in a Github Actions upon tagging

Most editors have their own implementation that shells out to jsonnet or tanka but that requires separate configuration of the JSONNET_PATH. It would be nice for the language server to do this, perhaps as a code action?
