This plugin aims to deliver a feature-rich, high quality, high performance IDE experience for Jsonnet. It is designed to work in large repositories with deeply nested imports.
- Syntax Highliting and Basic Editing features
- Snippets
- Custom linting code that is able to deal with large codebases
- The analysis code is optimized for real-time linting, and can return in <5ms when the normal linter could take minutes.
- Formatting
- Delta text update support for efficient editing
- Designed to remain performant in large repos with many files open
- Automatic detection of
bazel-binfor generated files - Type and Value Deduction
- Supports imported files
- Able to follow variables, function return values, and array/object indexing
- Autocomplete
- Stdlib support with documentation and typed signatures
- Scoped variable completion
- Dotted autocomplete
- Template object field completion
- Import path completion for files
- Go to Definition
- Can follow definitions in other files, including json files
- Hover Information
- Function Signature Help
- AST Recovery
- The LSP is able recover common syntax issues while typing (like a missing semicolon) for a smoother experience
These are features I consider pretty important that are still missing:
- More type deduction logic and analysis
- More IDE options (options for linting, jpath, etc)
- First class multi-dimension jsonnet support
- To develop the LSP, change the
jsonnet.lsp.binaryPathsetting to therunlsp.shscript in the root. Reloading the LSP in vscode (shift+cmd+p -> jsonnet: reload language server) will rebuild the server. - To develop the client, open
editor/codein vscode, and hit F5 to open a debug build of the client. Generally developing the LSP does not need a debug version of the client.
- Github actions are setup to publish to OpenVSX automatically when a release is created
- The LSP binaries are bundled into the
.vsixextension, to help reduce bugs from version skew and simplify installation.
