## Install In One Command!

Make sure you have the newest version of Neovim (0.5).

``` bash
bash <(curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/master/utils/installer/install.sh)
```

### Installing
The following command installs LunarVim.  Change `LVBRANCH` to the branch you'd like to install.  `master` for the stable branch and `rolling` for the latest changes.
``` bash
LVBRANCH=rolling bash <(curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/rolling/utils/installer/install.sh)
```

### BREAKING CHANGE on the rolling branch
* The latest changes to LunarVim require you to [remove it completely](https://github.com/ChristianChiarulli/LunarVim/wiki/Uninstalling-LunarVim) before upgrading
* Going forward LunarVim will no longer reside in the nvim configuration folder.  LunarVim has been moved to `~/.local/share/lunarvim`.  
* To launch Lunarvim use the new `lvim` command.  `nvim` will only launch standard neovim.  
* Your personal configuration file (`lv-config.lua`) can now be found in `~/.config/lvim`.  You can initialize this folder as a git repository to track changes to your configuration files.

### Fixing installation problems
If your installation is stuck on `Ok to remove? [y/N]`, it means there are some leftovers, \
you can run the script with `--overwrite` but be warned this will remove the following folders:
- `~/.cache/nvim`
- `~/.config/nvim`                        #Removed only on Master Branch
- `~/.local/share/nvim/site/pack/packer`  #Removed only on Master Branch
- `~/.local/share/lunarvim`               #Removed only on Rolling Branch
- `~/.config/lvim`                        #Removed only on Rolling Branch
```bash
curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/rolling/utils/installer/install.sh | LVBRANCH=rolling bash -s -- --overwrite
```
then run nvim and wait for treesitter to finish the installation


## Installing LSP for your language

Just enter `:LspInstall` followed by `<TAB>` to see your options

**NOTE** I recommend installing `lua` for autocomplete in `lv-config.lua`

For the julia language server look [here](https://github.com/ChristianChiarulli/LunarVim/wiki/Enabling-a-language-server#julia-support)

## Configuration file

To activate other plugins and language features use the `lv-config.lua` file provided in the `nvim` folder (`~/.config/nvim/lv-config.lua`) in the master branch or (`~/.config/lvim/lv-config.lua`) on rolling

Example:

```lua
-- O is the global options object

-- THESE ARE EXAMPLE CONFIGS FEEL FREE TO CHANGE TO WHATEVER YOU WANT
-- general
-- O.format_on_save = false -- to disbale formatting on save
-- O.lint_on_save = false -- to disable formatting on save
O.completion.autocomplete = true
O.default_options.relativenumber = true
O.colorscheme = 'spacegray'
O.default_options.timeoutlen = 100

-- keymappings 
O.keys.leader_key = "space"
-- overwrite the key-mappings provided by LunarVim for any mode, or leave it empty to keep them
O.keys.normal_mode = {
    -- Page down/up
  {'[d', '<PageUp>'},
  {']d', '<PageDown>'},
}
-- if you just want to augment the existing ones then use the utility function
require("lv-utils").add_keymap_insert_mode({ silent = true }, {
  { "<C-s>", ":w<cr>" },
  { "<C-c>", "<ESC>" }
})

-- you can also use the native vim way directly
vim.api.nvim_set_keymap("i", "<C-Space>", "compe#complete()", { noremap = true, silent = true, expr = true })

-- After changing plugin config it is recommended to run :PackerCompile
O.plugin.dashboard.active = true
O.plugin.terminal.active = true
O.plugin.zen.active = true

-- if you don't want all the parsers change this to a table of the ones you want
O.treesitter.ensure_installed = "all"
O.treesitter.ignore_install = {"haskell"}
O.treesitter.highlight.enabled = true

-- lua
O.lang.lua.autoformat = false
O.lang.lua.formatter = 'lua-format'

-- javascript
O.lang.tsserver.formatter = 'prettier'
O.lang.tsserver.linter = nil
O.lang.tsserver.autoformat = true

-- python
O.lang.python.diagnostics.virtual_text = true
O.lang.python.analysis.use_library_code_types = true
-- to change default formatter from yapf to black
-- O.lang.python.formatter.exe = "black"
-- O.lang.python.formatter.args = {"-"}
-- To change enabled linters
-- https://github.com/mfussenegger/nvim-lint#available-linters
-- O.lang.python.linters = { "flake8", "pylint", "mypy", ... }

-- go
-- to change default formatter from gofmt to goimports
-- O.lang.formatter.go.exe = "goimports"

-- Additional Plugins
-- O.user_plugins = {
--   {"folke/tokyonight.nvim"},
--   {
--     "ray-x/lsp_signature.nvim",
--     config = function()
--       require"lsp_signature".on_attach()
--     end,
--     event = "InsertEnter"
--   },
-- }

-- }

-- Autocommands (https://neovim.io/doc/user/autocmd.html)
-- O.user_autocommands = {{ "BufWinEnter", "*", "echo \"hi again\""}}

-- Additional Leader bindings for WhichKey
-- O.user_which_key = {
--   A = {
--     name = "+Custom Leader Keys",
--     a = { "<cmd>echo 'first custom command'<cr>", "Description for a" },
--     b = { "<cmd>echo 'second custom command'<cr>", "Description for b" },
--   },
-- }

-- To link your init.vim (until you find Lua replacements)
-- vim.cmd('source ' .. CONFIG_PATH .. '/lua/lv-user/init.vim')
```

In case you want to see all the settings inside LunarVim, run the following:

```bash
cd ~/.config/nvim
lvim --headless +'lua require("lv-utils").generate_settings()' +qa && sort -o lv-settings.lua{,}
```
and then inspect `~/.config/nvim/lv-settings.lua` file

## Updating LunarVim

In order to update you should be aware of three things `Plugins`, `LunarVim` and `Neovim`

To update plugins:

```
:PackerUpdate
```

To update LunarVim:

```bash
# Master Branch
cd ~/.config/nvim && git pull
:PackerSync  

# Rolling Branch
cd ~/.local/share/lunarvim && git pull
:PackerSync
```

To update Neovim use your package manager or [compile from source](https://github.com/ChristianChiarulli/LunarVim/wiki/Installation#get-the-latest-version-of-neovim)

## Project Goals

1. Provide basic functionalities required from an IDE
    - LSP
    - Formatting/Linting
    - Debugging
    - Treesitter
    - Colorschemes
2. Be as fast and lean as possible 
    - Lazy loading
    - Not a single extra plugin
    - User configurable lang/feature enable/disable
3. Provide a [simple and easy](https://github.com/LunarVim/LunarVimCommunity) way for users to share their own configuration or use others. 
4. Hot reload of configurations
    - Hot install of lsp/treesitter/formatter required upon openning a filetype for the first time
5. Provide a stable & maintainable error free configuration layer over neovim 
    - With the help of the community behind it
    - Github workflow testing
    - Freezing plugin versions
6. Provide detailed documentation
    - Video series on how to configure LunarVim as an IDE for each lang
7. Valhalla
