Nickel Language Server
NLS is a language server for the nickel programming language. NLS offer error messages, type hints, and auto-completion right in your favorite LSP-enabled editor.
Server
To be editor independent nls
is made up of two components the server and possible lsp-client configurations that talk to the server directly.
Hence, the server has to be installed separately to the client configuration.
Installation
The easiest way to install nls
is using nix. nls
is installed in the same installation as nickel
:
To enter a shell with nickel
and nls
run
nix shell github:tweag/nickel
Client
VS Code
NLS is currently not available through the vscode marketplace. In the meantime, it can be built using Nix.
Either using the command line (you need to have the jq
command available)
code --install-extension $(nix build ./\#vscodeExtension --no-link --json | jq ".[0].outputs.vsix")
or in two steps, by first building the extension
nix build github:tweag/nickel#vscodeExtension.vsix
then installing it using Extension: Install from VSIX
in the vscode command palette and choosing ./result-vsix/nls-client.vsix
.
Configuration
The VS Code extension offers three configuration options:
"nls.server.path"
: Path to nickel language server"nls.server.trace"
: "Enables performance tracing to the given file""nls.server.debugLog"
: "Logs the communication between VS Code and the language server."
