## 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.
* If you want to keep launching LunarVim with the `nvim` command, add an alias entry to your shell's config file: `alias nvim=lvim`. To temporarily revert to the default `nvim` prefix it with a backslash `\nvim`.
### 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 `` 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', ''},
{']d', ''},
}
-- if you just want to augment the existing ones then use the utility function
require("lv-utils").add_keymap_insert_mode({ silent = true }, {
{ "", ":w" },
{ "", "" }
})
-- you can also use the native vim way directly
vim.api.nvim_set_keymap("i", "", "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
-- you can set a custom on_attach function that will be used for all the language servers
-- See
-- O.lsp.on_attach_callback = function(client, bufnr)
-- local function buf_set_option(...)
-- vim.api.nvim_buf_set_option(bufnr, ...)
-- end
-- --Enable completion triggered by
-- buf_set_option("omnifunc", "v:lua.vim.lsp.omnifunc")
-- end
-- 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 = { "echo 'first custom command'", "Description for a" },
-- b = { "echo 'second custom command'", "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 /tmp
lvim --headless +'lua require("lv-utils").generate_settings()' +qa && sort -o lv-settings.lua{,}
```
and then inspect `/tmp/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/lvim && 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
