The module has been renamed from sveltecheck to svelte-check. See the Migration Guide for details.

Installation

Using lazy.nvim

1. Ensure lazy.nvim is set up in your Neovim configuration.
2. Add the plugin to your plugin list:

-- lazy.nvim plugin configuration
require('lazy').setup({
    {
        'nvim-svelte/nvim-svelte-check',
        config = function()
            require('svelte-check').setup({
                command = "pnpm run check", -- Default command for pnpm
            })
        end,
    },
})

or

return {
  {
    "nvim-svelte/nvim-svelte-check",
    config = function()
      require("svelte-check").setup({
        command = "pnpm run check", -- Default command for pnpm
      })
    end,
  },
}

Using packer.nvim

1. Ensure packer.nvim is set up in your Neovim configuration.
2. Add the plugin to your plugin list:

-- packer.nvim plugin configuration
return require('packer').startup(function(use)
    use {
        'nvim-svelte/nvim-svelte-check',
        config = function()
            require('svelte-check').setup({
                command = "pnpm run check", -- Default command for pnpm
            })
        end
    }

    -- Add other plugins as needed
end)

Usage

After installation, run the svelte-check command in Neovim:

:SvelteCheck

This command will start the svelte-check process, display a spinner, and populate the quickfix list with any errors or warnings found. A summary of the check will be printed upon completion.

Customization

Customize the plugin by passing configuration options to the setup function:

• command (string): The command to run svelte-check (default: "pnpm run check").
• spinner_frames (table): Frames for the spinner animation (default: { "⣾", "⣽", "⣻", "⢿", "⡿", "⣟", "⣯", "⣷" })
• debug_mode (boolean): Enable debug logging for troubleshooting (default: false)

Example Customization

require('svelte-check').setup({
    command = "npm run svelte-check", -- Custom command for npm, defaults to pnpm
    spinner_frames = { "⣾", "⣽", "⣻", "⢿", "⡿", "⣟", "⣯", "⣷" }, -- spinner frames
    debug_mode = false, -- will print debug messages if true (default is false)
})

Troubleshooting

If the plugin isn't correctly detecting errors or warnings:

1. Try enabling debug mode to see detailed logging:

   require('svelte-check').setup({
       command = "npm run check",
       debug_mode = true
   })

2. Verify that your project's svelte-check command works correctly in the terminal

3. Make sure the command in your config matches the exact script name in package.json

4. Check if your project uses a custom output format for svelte-check that might not be compatible with the plugin
