Use the LSP

Currently a fluwent install is possible for NeoVim and VSCode. However the language server protocol enables swift integration into other editors.

VS Code

Install the semantic web lsp extension (vscode or open-vscode). The extension starts the lsp from WASM and starts the vscode LSP client.

NeoVim

To use the LSP you will always have to install the binary. So do that first:

cargo install --git https://github.com/ajuvercr/semantic-web-lsp --bin lsp-bin

Or locally

git clone https://github.com/ajuvercr/semantic-web-lsp.git
cargo install --path lsp-bin

Configure the LSP in NeoVim.

#  Add a config to lspconfig.configs
local configs = require("lspconfig.configs")

configs.jsonld = {
  default_config = {
    cmd = { 'lsp-bin' },
    filetypes = { 'jsonld', 'turtle', 'sparql' },
    root_dir = require("lspconfig.util").find_git_ancestor,
    single_file_support = true,
    init_options = {},
  }
}

# Start the LSP
local lspconfig = require("lspconfig")

lspconfig.jsonld.setup {
  on_attach = M.on_attach,
  capabilities = M.capabilities,
}
