# Editors integration
There are several extensions available to integrate `zk` in your favorite editor:
* [`zk.nvim`](https://github.com/megalithic/zk.nvim) for Neovim 0.5+, maintained by [Seth Messer](https://github.com/megalithic)
* [`zk-vscode`](https://github.com/mickael-menu/zk-vscode) for Visual Studio Code
## Language Server Protocol
`zk` ships with a [Language Server](https://microsoft.github.io/language-server-protocol/overviews/lsp/overview/) to provide basic support for any LSP-compatible editor. The currently supported features are:
* Auto-complete Markdown links with `[[` (setup wiki-links in the [note formats configuration](note-format.md))
* Auto-complete [hashtags and colon-separated tags](tags.md).
* Preview the content of a note when hovering a link.
* Navigate in your notes by following internal links.
* Create a new note using the current selection as title.
* Diagnostics for dead links and wiki-links titles.
* [And more to come...](https://github.com/mickael-menu/zk/issues/22)
You can configure some of these features in your notebook's [configuration file](config-lsp.md).
### Editor LSP configurations
To start the Language Server, use the `zk lsp` command. Refer to the following sections for editor-specific examples. [Feel free to share the configuration for your editor](https://github.com/mickael-menu/zk/issues/22).
#### Vim and Neovim
##### Vim and Neovim 0.4
With [`coc.nvim`](https://github.com/neoclide/coc.nvim), run `:CocConfig` and add the following in the settings file:
<details><summary><tt>coc-settings.json</tt></summary>
```jsonc
{
// Important, otherwise link completion containing spaces and other special characters won't work.
"suggest.invalidInsertCharacters": [],
"languageserver": {
"zk": {
"command": "zk",
"args": ["lsp"],
"trace.server": "messages",
"filetypes": ["markdown"]
},
}
}
```
</details>
Here are some additional useful key bindings and custom commands:
<details><summary><tt>~/.config/nvim/init.vim</tt></summary>
```viml
" User command to index the current notebook.
"
" zk.index expects a notebook path as first argument, so we provide the current
" buffer path with expand("%:p").
command! -nargs=0 ZkIndex :call CocAction("runCommand", "zk.index", expand("%:p"))
nnoremap <leader>zi :ZkIndex<CR>
" User command to create and open a new note, to be called like this:
" :ZkNew {"title": "An interesting subject", "dir": "inbox", ...}
"
" Note the concatenation with the "edit" command to open the note right away.
command! -nargs=? ZkNew :exec "edit ".CocAction("runCommand", "zk.new", expand("%:p"), <args>).path
" Create a new note after prompting for its title.
nnoremap <leader>zn :ZkNew {"title": input("Title: ")}<CR>
" Create a new note in the directory journal/daily.
nnoremap <leader>zj :ZkNew {"dir": "journal/daily"}<CR>
```
</details>
##### Neovim 0.5 built-in LSP client
Using [`nvim-lspconfig`](https://github.com/neovim/nvim-lspconfig):
<details><summary><tt>~/.config/nvim/init.lua</tt></summary>
```lua
local lspconfig = require('lspconfig')
local configs = require('lspconfig/configs')
configs.zk = {
default_config = {
cmd = {'zk', 'lsp'},
filetypes = {'markdown'},
root_dir = function()
return vim.loop.cwd()
end,
settings = {}
};
}
lspconfig.zk.setup({ on_attach = function(client, buffer)
-- Add keybindings here, see https://github.com/neovim/nvim-lspconfig#keybindings-and-completion
end })
```
</details>
#### Sublime Text
Install the [Sublime LSP](https://github.com/sublimelsp/LSP) package, then run the **Preferences: LSP Settings** command. Add the following to the settings file:
<details><summary><tt>LSP.sublime-settings</tt></summary>
```jsonc
{
"clients": {
"zk": {
"enabled": true,
"command": ["zk", "lsp"],
"languageId": "markdown",
"scopes": [ "source.markdown" ],
"syntaxes": [ "Packages/MarkdownEditing/Markdown.sublime-syntax" ]
}
}
}
```
</details>
#### Visual Studio Code
Install the [`zk-vscode`](https://marketplace.visualstudio.com/items?itemName=mickael-menu.zk-vscode) extension from the Marketplace.
### Custom commands
Using `zk`'s LSP custom commands, you can call `zk` commands right from your editor. Please refer to your editor's documentation on how to bind keyboard shortcuts to custom LSP commands.
#### `zk.index`
This LSP command calls `zk index` to refresh your notebook's index. It can be useful to make sure that the auto-completion is up-to-date. `zk.index` takes two arguments:
1. A path to a file or directory in the notebook to index.
2. <details><summary>(Optional) A dictionary of additional options (click to expand)</summary>
| Key | Type | Description |
|---------|---------|-----------------------------------|
| `force` | boolean | Reindexes all the notes when true |
</details>
`zk.index` returns a dictionary of indexing statistics.
#### `zk.new`
This LSP command calls `zk new` to create a new note. It can be useful to quickly create a new note with a key binding. `zk.new` takes two arguments:
1. A path to any file or directory in the notebook, to locate it.
2. <details><summary>(Optional) A dictionary of additional options (click to expand)</summary>
| Key | Type | Description |
|------------------------|----------------------|-------------------------------------------------------------------------------------------|
| `title` | string | Title of the new note |
| `content` | string | Initial content of the note |
| `dir` | string | Parent directory, relative to the root of the notebook |
| `group` | string | [Note configuration group](config-group.md) |
| `template` | string | [Custom template used to render the note](template-creation.md) |
| `extra` | dictionary | A dictionary of extra variables to expand in the template |
| `date` | string | A date of creation for the note in natural language, e.g. "tomorrow" |
| `edit` | boolean | When true, the editor will open the newly created note (**not supported by all editors**) |
| `insertLinkAtLocation` | location<sup>1</sup> | A location in another note where a link to the new note will be inserted |
The `location` type is an [LSP Location object](https://microsoft.github.io/language-server-protocol/specification#location), for example:
```json
{
"uri":"file:///Users/mickael/notes/9se3.md",
"range": {
"end":{"line": 5, "character":149},
"start":{"line": 5, "character":137}
}
}
```
</details>
`zk.new` returns a dictionary with the key `path` containing the absolute path to the newly created file.
#### `zk.list`
This LSP command calls `zk list` to search a notebook. It takes two arguments:
1. A path to any file or directory in the notebook, to locate it.

1. As the output of this command might be very verbose and put a heavy load on the LSP client, you need to explicitly set which note fields you want to receive with the `select` option. The following fields are available: `filename`, `filenameStem`, `path`, `absPath`, `title`, `lead`, `body`, `snippets`, `rawContent`, `wordCount`, `tags`, `metadata`, `created`, `modified` and `checksum`.

`zk.list` returns the found notes as a JSON array.
#### `zk.tag.list`

1. A path to any file or directory in the notebook, to locate it.
2. <details><summary>(Optional) A dictionary of additional options (click to expand)</summary>
| Key | Type | Required? | Description |
|--------|--------------|-----------|--------------------------------------------------|
| `sort` | string array | No | Order the tags by the given criteria<sup>1</sup> |
1. The available sort criteria are `name` and `note-count`. You can change the order by appending `-` or `+` to the criterion.
</details>
`zk.tag.list` returns the tags as a JSON array.
