## Supported LSP capabilities

| LSP Features                                                                                                                                           | Behavior                                                                                                                 |
| ------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------ |
| [textDocument/definition](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_definition)         | Go to the first definition found in the `.bib` files.                                                                    |

## Configuration

Create a configuration file `.bibli.toml` at the root of your note directory. Here is a sample configuration. For the complete list of configurations, refer to the [documentation](/docs/configurations.md) and the [default config](/docs/default-config.toml).

```toml

[backends] # Specifying backends for bibtex libraries
# Backends can be of any names, e.g.,
[backends.mylib]
backend_type = "bibfile" # Available backends: "bibfile", "zotero_api"
bibfiles = ["references.bib"]

[backends.my_lab_lib]
backend_type = "zotero_api"
library_id = "5123456" # Your library ID
library_type = "user" # "user"" or "group"
api_key = "XXXXXXXXXXXXXXXXXXXXXXXX"

[cite] # How to cite bibtex entires, e.g., "[@john2024paper]"
trigger = "@"

[view] # How to display your document externally
viewer = "browser" # Available viewer: `zotero`, `zotero_bbt` and `browser`

[hover.doc_format] # How to display hover documentation
show_fields = ["abstract", "year", "booktitle", "url"]
format = "table" # Available formats: "table"  and "list" (markdown)

[completion.doc_format] # How to display hover documentation
show_fields = ["abstract", "year", "booktitle"]
format = "list"

```

### Backends

Currently, Bibli supports `bibfile` and `zotero_api` backends.

- `bibfile` backend loads the library from a local bibtex file.
- `zotero_api` backend connects directly to your Zotero web library, removing the need for maintaining separated bibfiles. It cache the results in a bibfile named `.{backend name}_{library type}_{library id}.bib`. Run the command LSP `library.reload_all` to refetch the online content.
  - [More on setting up citation keys for online libraries](/docs/custom-cite-keys.md)

### Viewers

We support openning the `url` in browser, or openning PDF attachment (for zotero-based backends). TODO: support custom PDF viewer. The current viewers are:

- `browser`: opens the `url` field in the bibtx entry in your default browser
- `zotero_bbt` shows the document in Zotero's PDF viewer (require [better bibtex](https://retorque.re/zotero-better-bibtex/) to be installed and Zotero to be running)
- `zotero` shows the entry in Zotero.

### Neovim configuration

Automatic configuration through [lspconfig](<>) has yet to be supported. To enable bibli-ls, put the following code in your Neovim config.

```lua
local lspconfig = require("lspconfig")
local configs = require("lspconfig.configs")

if not configs.bibli_ls then
  configs.bibli_ls = {
    default_config = {
      cmd = { "bibli_ls" },
      filetypes = { "markdown" },
      root_dir = lspconfig.util.root_pattern(".bibli.toml"),
      -- Optional: visit the URL of the citation with LSP DocumentImplementation
      on_attach = function(client, bufnr)
        vim.keymap.set({ "n" }, "<cr>", function()
          vim.lsp.buf.implementation()
        end)
      end,
    },
  }
end

lspconfig.bibli_ls.setup({})
```

### Helix configuration

To enable bibli-ls, put the following code in your Helix config (`.config/helix/languages.toml`):

```toml
  [language-server.bibli-ls]
  command = "bibli_ls"
  required-root-patterns = [".bibli.toml"]

  [[language]]
  name = "markdown"
  language-servers = ["bibli-ls"]  # Add other md lsps like zk, marksman, ...
  roots = [".bibli.toml"]
```

## Installation

Install the latest release of `bibli-ls` through `pip`:

```bash
pip install bibli-ls

# Alternatively, on Arch:
pipx install bibli-ls
```

## Using Nix

### Installation via Flakes

In your `flake.nix`:

```nix
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    bibli-ls = {
      url = "github:kha-dinh/bibli-ls";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  # ...
  outputs =
    {
      self,
      bibli-ls,
      nixpkgs,
      ...
    }@inputs:
    let
      pkgs-flake = {
        bibli-ls = bibli-ls.packages.${system}.default;
      };

      customOverlays = [
        (final: prev: {
          flake = pkgs-flake;
        })
      ];
    in
      nixosConfigurations = {
        yourMachine = nixpkgs.lib.nixosSystem {
          inherit system;
          modules = [
            { nixpkgs.overlays = customOverlays; }
            # ...
          ];
        };
      };
}
```

Then you can use it in your configuration:

```nix
{
  environment.systemPackages = [ pkgs.flake.bibli-ls ];
}
```

### Home Manager Configuration

Add bibli-ls to your home-manager configuration:

```nix
{ config, pkgs, ... }:
{
  home.packages = [ pkgs.flake.bibli-ls ];

  home.file."Sync/Notes/zk/permanent/.bibli.toml".text = ''
    [backends]
    [backends.library]
    backend_type = "bibfile"
    bibfiles = ["${config.home.homeDirectory}/Sync/Bibliography/library.bib"]
  '';
}
```

## Building from source

From the root directory:

```bash
pip install . # --force-reinstall if needed
# Or for Arch
pipx install . # --force-reinstall if needed
# And Nix
nix build # The built package will be available in `./result`. You can also use `nix run`
```
