# Configuration
|
||||
|
||||
To override global configuration parameters create a `config.toml` file located in your config directory (i.e `~/.config/helix/config.toml`).
|
||||
|
||||
## LSP
|
||||
|
||||
To disable language server progress report from being displayed in the status bar add this option to your `config.toml`:
|
||||
```toml
|
||||
lsp-progress = false
|
||||
```
|
||||
|
||||
## Theme
|
||||
|
||||
Use a custom theme by placing a theme.toml in your config directory (i.e ~/.config/helix/theme.toml). The default theme.toml can be found [here](https://github.com/helix-editor/helix/blob/master/theme.toml), and user submitted themes [here](https://github.com/helix-editor/helix/blob/master/contrib/themes).
|
||||
|
||||
Styles in theme.toml are specified of in the form:
|
||||
|
||||
```toml
|
||||
key = { fg = "#ffffff", bg = "#000000", modifiers = ["bold", "italic"] }
|
||||
```
|
||||
|
||||
where `name` represents what you want to style, `fg` specifies the foreground color, `bg` the background color, and `modifiers` is a list of style modifiers. `bg` and `modifiers` can be omitted to defer to the defaults.
|
||||
|
||||
To specify only the foreground color:
|
||||
|
||||
```toml
|
||||
key = "#ffffff"
|
||||
```
|
||||
|
||||
if the key contains a dot `'.'`, it must be quoted to prevent it being parsed as a [dotted key](https://toml.io/en/v1.0.0#keys).
|
||||
|
||||
```toml
|
||||
"key.key" = "#ffffff"
|
||||
```
|
||||
|
||||
Possible modifiers:
|
||||

|

|

| `ui.selection` | For selections in the editing area |
|

| `warning` | LSP warning |
|
||||
| `error` | LSP error |
|

| `info` | LSP info |
|
||||
| `hint` | LSP hint |
|
||||
|
||||
These keys match [tree-sitter scopes](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#theme). We half-follow the common scopes from [macromates language grammars](https://macromates.com/manual/en/language_grammars) with some differences.
|
||||
|
||||
For a given highlight produced, styling will be determined based on the longest matching theme key. So it's enough to provide function to highlight `function.macro` and `function.builtin` as well, but you can use more specific scopes to highlight specific cases differently.

# Themes
|
||||
|
||||
First you'll need to place selected themes in your `themes` directory (i.e `~/.config/helix/themes`), the directory might have to be created beforehand.
|
||||
|
||||
To use a custom theme add `theme = <name>` to your [`config.toml`](./configuration.md) or override it during runtime using `:theme <name>`.
|
||||
|
||||
The default theme.toml can be found [here](https://github.com/helix-editor/helix/blob/master/theme.toml), and user submitted themes [here](https://github.com/helix-editor/helix/blob/master/contrib/themes).
|
||||
|
||||
## Creating a theme
|
||||
|
||||
First create a file with the name of your theme as file name (i.e `mytheme.toml`) and place it in your `themes` directory (i.e `~/.config/helix/themes`).
|
||||
|
||||
Each line in the theme file is specified as below:
|
||||
|
||||
```toml
|
||||
key = { fg = "#ffffff", bg = "#000000", modifiers = ["bold", "italic"] }
|
||||
```
|
||||
|
||||
where `key` represents what you want to style, `fg` specifies the foreground color, `bg` the background color, and `modifiers` is a list of style modifiers. `bg` and `modifiers` can be omitted to defer to the defaults.
|
||||
|
||||
To specify only the foreground color:
|
||||
|
||||
```toml
|
||||
key = "#ffffff"
|
||||
```
|
||||
|
||||
if the key contains a dot `'.'`, it must be quoted to prevent it being parsed as a [dotted key](https://toml.io/en/v1.0.0#keys).
|
||||
|
||||
```toml
|
||||
"key.key" = "#ffffff"
|
||||
```
