Go Rust Jsonnet Language Server

This is a jsonnet language server using the go-jsonnet implementation to generate the AST and evaluate jsonnet code

For a small list of example videos head to the Showcase page.

This repository contains 3 components:

Roadmap

• [-] Completion
  • Global completion
  • Index completion
  • Value preview
    • Make the Object preview pretty
  • [-] Complete “everything”
    • Find the remaining cases where completion does not work/tries to complete the wrong node
  • Stdlib
  • [-] Advanced Stdlib completion
    • extVar completion
    • Return values
    • Function parameters from std.map
  • Complete Loops
    • Use std.map for loops
  • All jsonnet imports
    • Properly handle completion if “/” is already in the string
  • self
  • super
    • Fix super not working if it never had an index
  • [-] Keyword completion
    • Only complete if valid
    • Add missing keywords
  • [-] Conditionals
    • Actually evaluate the condition
  • Default parameters
  • Builder pattern
    • Check extremely complex patterns
  • Array access
  • Unused function arguments
• Semantic tokens
• [-] Inlay Hints
  • Function parameters
    • Only update if needed
  • Indices
  • Name after long objects
• Goto definition
  • Goto file from import string
  • Can goto everything we can complete
• Find reference
  • Import strings
  • Can find references for all identifiers we can goto
• Rename
  • Rename imports if file is renamed
  • Rename file if import is renamed
  • Can rename all identifiers we can find the reference of
• Signature Help
• Docsonnet support
  • How to handle the license issues? Docsonnet does not have an open source license
    • Just evaluate it
  • Handle the stdlib the same as docsonnet?
  • Signature help parameters
• [-] AST repair
• Commands
  • Evaluate file
• Missing LSP features
  • Code actions
  • Code Lense?
  • Hover
  • Document highlight
  • Document/Workspace symbols
  • Folding
  • Call hierachie
  • File operation support for automatic refactoring (like renaming imports)
• Improve performance
  • Test rust2go mem
  • More multithreading
• More tests
  • Fix ignored tests
• (Major) Code cleanup
  • Once the prototyping phase is over

Known Issues

• (Go)-Jsonnet bugs
  • If you import foo.libsonnet and there is also a foo.libsonnet in the current working directory, evaluating the snippet will result in a diagnostic error
    • To reproduce cat mydir/bar.jsonnet | jsonnet --jpath mydir -
  • If there is a circular dependency go-jsonnet emits a strange error
• Eval diagnostics are always use the state from disk and not from memory

Jsonnet Quirks

• tailstrict
  • not part of the spec apart from the reserved keyword
  • no documentation at all
  • in foo(myArg()) tailstrict forces myArg to be evaluated before the body, even if it is unused

Neovim

To get autocompletion for the config, it is best to put the config in a json file next to the actual lsp configuration. To do that, just put a grustonnet-ls.lua file in your after/lsp directory with the following content. The config will be loaded from a grustonnet.json file.

local function getJson(filename)
	-- https://neovim.io/doc/user/lua.html#lua-script-location
	local current_file = debug.getinfo(1, "S").source:sub(2)
	local current_dir = vim.fn.fnamemodify(current_file, ":h")

	local file_content = vim.fn.readfile(current_dir .. "/" .. filename)
	return vim.json.decode(table.concat(file_content, "\n"))
end

local grustonnet_settings = getJson("grustonnet.json");
return {
	cmd = { "grustonnet-ls" },
	filetypes = { 'jsonnet', 'libsonnet' },
	root_markers = { 'jsonnetfile.json', '.git' },
	settings = grustonnet_settings,
}

To get a live preview and debugger support you can install my jsonnet-tools plugin

VSCodium

IntelliJ

Just don’t. IntelliJ is probably nice for Java development, but for other languages it just seems rather bad and does not have native support LSP, DAP, or Treesitter.

To get basic support you can use lsp4ij. However, you either need to separately install syntax highlighting or use the slow Treesitter bridge of the language server.

Dev Setup

To get a dev environment just install Nix and run nix develop . To automatically enter the dev-shell install direnv and run direnv allow

Building containers

To ensure reproducibility there is no Dockerfile and all images are built using Nix. Run nix build .#dockerImageFull do build the full image.

To directly load the image into Podman you can use nix run .#dockerImageFull.copyToPodman
