      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the

          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one

          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

# lsp-setup.nvim

A simple wrapper for [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) and [mason-lspconfig](https://github.com/mason-org/mason-lspconfig.nvim) (optional) to easily setup LSP servers.

## Requirements

- Neovim >= 0.11
- nvim-lspconfig >= 2.0.0
- mason.nvim & mason-lspconfig.nvim (optional)

## Installation

### [lazy.nvim](https://github.com/folke/lazy.nvim)

```
{
  'junnplus/lsp-setup.nvim',
  dependencies = {
    'neovim/nvim-lspconfig',
    'mason-org/mason.nvim', -- optional
    'mason-org/mason-lspconfig.nvim', -- optional
  },
  ---@type LspSetup.Options
  opts = {
    servers = {
      pylsp = {},
      clangd = {}
    }
  }
}
```

## Usage

```lua
require('lsp-setup').setup({
  servers = {
    pylsp = {},
    clangd = {}
  }
})
```

You can replace `pylsp` with the LSP server name you need, see [available LSPs](https://github.com/neovim/nvim-lspconfig/blob/master/doc/configs.md).

Also support installing custom versions of LSP servers (requires mason and mason-lspconfig), for example:

```lua
require('lsp-setup').setup({
  servers = {
    ['rust_analyzer@nightly'] = {}
  }
})
```

LSP servers returns a table will automatically setup server process using lspconfig. You can also pass a nil function to setup the server manually, see [Integrations/rust-tools.nvim](#rust-toolsnvim).

require('lsp-setup').setup({
