# Installation Guide

1. Get the code

git clone https://github.com/nickkadutskyi/jb.nvim

Downloads the entire project code from GitHub to your computer.

cd jb.nvim

Moves into the project folder you just downloaded.

2. Gradle (Java/Kotlin)

Medium Recommended

Prerequisites

Git Needed to download the project code from GitHub.
JDK (Java) Required to build and run Java/Kotlin projects.
Gradle If the repo includes gradlew (Gradle Wrapper), you don't need to install Gradle separately.

⚠️ This is a large repository, so this method may point to an internal sub-package rather than the actual core product. Check the full README as well.

cd tools/intellij-palette-exporter

This project's files live in a subfolder, so move into it first.

./gradlew build

Builds the project using Gradle.

✅ A BUILD SUCCESSFUL message means it worked. The output is created under build/.

## Installation

Install the theme with your preferred package manager, such as
[folke/lazy.nvim](https://github.com/folke/lazy.nvim):

```lua
return {
    "nickkadutskyi/jb.nvim",
    lazy = false,
    priority = 1000,
    opts = {},
    config = function()
        -- require("jb").setup({transparent = true})
        vim.cmd("colorscheme jb")
    end,
}
```
### Plugin Notes

#### hrsh7th/nvim-cmp

If you use `custom` view for entries (opts>view>entries>name) cmp creates
a custom window instead of native built-in popup. To improve the view you
can link highlight groups like this:

```lua
window = {
    completion = cmp.config.window.bordered({
        winhighlight = "Normal:Pmenu,FloatBorder:DialogFloatBorder,CursorLine:PmenuSel,Search:None",
    }),
    documentation = cmp.config.window.bordered({
        winhighlight = "Normal:Pmenu,FloatBorder:DialogFloatBorder,CursorLine:PmenuSel,Search:None",
    }),
},
```
You can have any config just make sure `Normal:Pmenu` and
`CursorLine:PmenuSel` is present in `winhighlight`.

### Usage

```lua
vim.cmd("colorscheme jb")
```

```vim
colorscheme jb
```

Change light/dark theme:

```lua
vim.o.background = "light"
```

```vim
set background=light
```

## Configuration

> [!IMPORTANT]
> Set the configuration **BEFORE** loading the color scheme `colorscheme jb`.

<details>
  <summary>Default Options</summary>

```lua
---@class jb.Config
M.defaults = {
    -- Disable bold or italic for all highlights
    disable_hl_args = {
        bold = false,
        italic = false,
    },
    -- Control snacks.nvim related styles
    snacks = {
        explorer = {
            -- Enable folke/snacks.nvim styling for explorer
            enabled = true,
        },
    },
    telescope = {
        -- Enable telescope.nvim styling
        enabled = true,
    },
    -- Type: jb.DisabledPlugin[]
    -- Disable plugin highlight sets by plugin id, e.g. "nvim-telescope/telescope.nvim"
    disabled_plugins = {},
    -- Enable this to remove background from Normal and NormalNC
    transparent = false,
    -- Enable colorblind-friendly palette (light mode only)
    -- Replaces green/purple/teal tokens with blue and near-black alternatives
    colorblind = false,
    integrations = {
        -- Match Ghostty's background to the statusbar while Neovim is open
        ghostty = false,
    },
}
```

## Overriding Colors & Highlight Groups

n/a

## Extras

Extra color configs for [Kitty](https://sw.kovidgoyal.net/kitty/conf.html),
[Alacritty](https://github.com/alacritty/alacritty),
[Ghostty](https://ghostty.org/) can be found in [extras](extras/).
To use them, refer to their respective documentation.

Set `integrations.ghostty = true` before loading the colorscheme to temporarily
match Ghostty's background to the JB statusbar. Ghostty's configured background
is restored when Neovim exits.

> [!NOTE]
> This integration sets a fixed Ghostty background using OSC 11. While the
> override is active, Ghostty cannot notify Neovim of background changes when
> the system switches between light and dark appearances. To keep
> `vim.o.background` synchronized with the system theme, use
> [f-person/auto-dark-mode.nvim](https://github.com/f-person/auto-dark-mode.nvim)
> together with this integration.

## Development

IntelliJ color snapshots come from the private plugin in
[tools/intellij-palette-exporter](tools/intellij-palette-exporter). That generated
file is stored in `lua/jb/intellij-palette.json`; Neovim highlight mappings are
stored separately in `lua/jb/highlights.json`.

When changing either palette file, regenerate the compiled palette used at runtime:

```sh
nvim --headless -u NONE --noplugin \
  +'set runtimepath^=/absolute/path/to/jb.nvim' \
  +'lua dofile("/absolute/path/to/jb.nvim/scripts/generate_palette_compiled.lua")' \
  +qa
```
