### Language Server configuration
|

## Language Server configuration
|
||||
|
||||
The `language-server` field takes the following keys:
|
||||
Language servers are configured separately in the table `language-server` in the same file as the languages `languages.toml`
|
||||
|
||||
| Key | Description |
|
||||
| --- | ----------- |
|
||||
| `command` | The name of the language server binary to execute. Binaries must be in `$PATH` |
|
||||
| `args` | A list of arguments to pass to the language server binary |
|
||||
| `timeout` | The maximum time a request to the language server may take, in seconds. Defaults to `20` |
|
||||
| `language-id` | The language name to pass to the language server. Some language servers support multiple languages and use this field to determine which one is being served in a buffer |
|
||||
| `environment` | Any environment variables that will be used when starting the language server `{ "KEY1" = "Value1", "KEY2" = "Value2" }` |
|
||||
For example:
|
||||
|
||||
The top-level `config` field is used to configure the LSP initialization options. A `format`
|
||||
sub-table within `config` can be used to pass extra formatting options to
|
||||
[Document Formatting Requests](https://github.com/microsoft/language-server-protocol/blob/gh-pages/_specifications/specification-3-16.md#document-formatting-request--leftwards_arrow_with_hook).
|
||||
```toml
|
||||
[language-server.mylang-lsp]
|
||||
command = "mylang-lsp"
|
||||
args = ["--stdio"]
|
||||
config = { provideFormatter = true }
|
||||
environment = { "ENV1" = "value1", "ENV2" = "value2" }
|
||||
|
||||
[language-server.efm-lsp-prettier]
|
||||
command = "efm-langserver"
|
||||
|
||||
[language-server.efm-lsp-prettier.config]
|
||||
documentFormatting = true
|
||||
languages = { typescript = [ { formatCommand ="prettier --stdin-filepath ${INPUT}", formatStdin = true } ] }
|
||||
```
|
||||
|
||||
These are the available options for a language server.
|
||||
|
||||
| Key | Description |
|
||||
| ---- | ----------- |
|
||||
| `command` | The name or path of the language server binary to execute. Binaries must be in `$PATH` |
|
||||
| `args` | A list of arguments to pass to the language server binary |
|
||||
| `config` | LSP initialization options |
|
||||
| `timeout` | The maximum time a request to the language server may take, in seconds. Defaults to `20` |
|
||||
| `environment` | Any environment variables that will be used when starting the language server `{ "KEY1" = "Value1", "KEY2" = "Value2" }` |
|
||||
|
||||
A `format` sub-table within `config` can be used to pass extra formatting options to
|
||||
[Document Formatting Requests](https://github.com/microsoft/language-server-protocol/blob/gh-pages/_specifications/specification-3-17.md#document-formatting-request--leftwards_arrow_with_hook).
|
||||
For example with typescript:
|
||||
|
||||
```toml
|
||||
[language-server.typescript-language-server]
|
||||
# pass format options according to https://github.com/typescript-language-server/typescript-language-server#workspacedidchangeconfiguration omitting the "[language].format." prefix.
|
||||
config = { format = { "semicolons" = "insert", "insertSpaceBeforeFunctionParenthesis" = true } }
|
||||
```
|
||||
|
||||
### Configuring Language Servers for a language
|
||||
|
||||
The `language-servers` attribute in a language tells helix which language servers are used for this language.
|
||||
|
||||
They have to be defined in the `[language-server]` table as described in the previous section.
|
||||
|
||||
Different languages can use the same language server instance, e.g. `typescript-language-server` is used for javascript, jsx, tsx and typescript by default.
|
||||
|
||||
In case multiple language servers are specified in the `language-servers` attribute of a `language`,
|
||||
it's often useful to only enable/disable certain language-server features for these language servers.
|
||||
|
||||
For example `efm-lsp-prettier` of the previous example is used only with a formatting command `prettier`,
|
||||
so everything else should be handled by the `typescript-language-server` (which is configured by default)
|
||||
The language configuration for typescript could look like this:
|
||||
|
||||
```toml
|
||||
[[language]]
|
||||
name = "typescript"
|
||||
auto-format = true
|
||||
# pass format options according to https://github.com/typescript-language-server/typescript-language-server#workspacedidchangeconfiguration omitting the "[language].format." prefix.
|
||||
config = { format = { "semicolons" = "insert", "insertSpaceBeforeFunctionParenthesis" = true } }
|
||||
language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ]
|
||||
```
|
||||
|
||||
or equivalent:
|
||||
|
||||
```toml
|
||||
[[language]]
|
||||
name = "typescript"
|
||||
language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ]
|
||||
```
|
||||
|
||||
Each requested LSP feature is prioritized in the order of the `language-servers` array.
|
||||
For example the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`).
|
||||
The features `diagnostics`, `code-action`, `completion`, `document-symbols` and `workspace-symbols` are an exception to that rule, as they are working for all language servers at the same time and are merged together, if enabled for the language.
|
||||
If no `except-features` or `only-features` is given all features for the language server are enabled.
|
||||
If a language server itself doesn't support a feature the next language server array entry will be tried (and so on).
|
||||
|
||||
The list of supported features is:
|
||||
|
||||
- `format`
|
||||
- `goto-definition`
|
||||
- `goto-declaration`
|
||||
- `goto-type-definition`
|
||||
- `goto-reference`
|
||||
- `goto-implementation`
|
||||
- `signature-help`
|
||||
- `hover`
|
||||
- `document-highlight`
|
||||
- `completion`
|
||||
- `code-action`
|
||||
- `workspace-command`
|
||||
- `document-symbols`
|
||||
- `workspace-symbols`
|
||||
- `diagnostics`
|
||||
- `rename-symbol`
|
||||
- `inlay-hints`
|
||||
