Troubleshooting

Missing Syntax Highlighting

1. Ensure nvim-treesitter is installed:

   :TSInstallInfo

   Confirm fe is listed under "Parsers installed."

2. Check queries:

   :lua print(vim.inspect(vim.api.nvim_get_runtime_file("queries/fe/*.scm", true)))

   Ensure fe queries are loaded.

---

Missing LSP Features

1. Ensure fe-language-server is installed and available in your PATH.

2. Check the LSP client:

   :LspInfo

   Confirm the Fe LSP client is listed and attached.

Reinstall the Plugin

Delete the runtime directories to force reinstallation:

rm -rf ~/.local/share/nvim/tree-sitter-fe
rm -rf ~/.local/share/nvim/nvim-fe-runtime

Restart Neovim and the plugin will reinitialize.
