NemCSS

Appearance

Config File Autocomplete ​

Editing nemcss.config.json gets you completion, hover docs, and validation for the config shape itself: property names, types, and required fields. This is separate from the LSP that completes generated classes inside your CSS and markup.

VS Code with the nemcss extension ​

Install the NemCSS extension and you get autocomplete in the config for free. Open any nemcss.config.json and you get completion, hover text, and red squiggles on invalid keys automatically.

Neovim (jsonls) ​

Associate the schema manually. This is a workaround until nemcss is registered in the SchemaStore catalog; once that ships, schemastore.nvim users get it automatically.

lua
require("lspconfig").jsonls.setup({
  settings = {
    json = {
      schemas = {
        {
          fileMatch = { "nemcss.config.json" },
          url = "https://liv7c.github.io/nemcss/schema/nemcss.config.schema.json",
        },
      },
    },
  },
})

Any other editor ​

Add a "$schema" key to your config:

json
{
  "$schema": "https://liv7c.github.io/nemcss/schema/nemcss.config.schema.json",
  ...
}

This is the fallback, not the recommendation. Most editors do it via filename association above, without touching the config file.
