astral.nvim

astral.nvim is a Neovim plugin for colorscheme persistence.

This very simple plugin allows Neovim to remember the last used colorscheme and restore it when Neovim opens.

Features

• Remembers the last used colorscheme and restores it when Neovim opens.
• Allows setting fallback themes if the saved colorscheme is not available.

Installation

Using lazy.nvim, add the plugin to your configuration:

require("lazy").setup({
    {
        "rootiest/astral.nvim",
        version = "*", -- Pin to GitHub releases
    },
})

Configuration

You can configure the astral plugin by passing a table of options to require("astral").setup().

Default Values

The default values for astral configuration are:

local config = {
    fallback_themes = { -- Default fallback themes
        "catppuccin",
        "tokyonight",
        "default"
    },
}

Example Configuration

To set the options for astral, use the following lazy.nvim configuration:

require("lazy").setup({
    {
        "astral/astral.nvim",
        version = "*", -- Pin to GitHub releases
        opts = {
            fallback_themes = { -- Customize fallback themes
                "catppuccin",
                "tokyonight",
                "default"
            },
        }
    },
})

Commands

• :Astral reset: Reset the colorscheme management.
• :Astral restore: Restore the last used colorscheme.

Autocommands

• ColorScheme: Store the new name when the colorscheme changes.

Troubleshooting

If you encounter issues with astral.nvim, here are some common problems and solutions:

1. Colorscheme not restoring on startup:

   • Ensure restore_colors is set to true in the configuration.
   • Check if vim.g.COLORTHEME is set and holds the correct colorscheme name.

2. Fallback themes not applied:

   • Verify that the fallback_themes array in the configuration contains valid colorscheme names.
   • Ensure that the fallback themes are installed and available in Neovim.

3. Unknown Astral command error:

   • Ensure you are using valid commands. The available commands are:
     • :Astral reset
     • :Astral restore

4. Colorscheme changes not saved:

   • Ensure there are no errors in the autocommand that triggers on the ColorScheme event.
   • Check if vim.g.COLORTHEME is being updated correctly when you change the colorscheme.
