Configuration

To override global configuration parameters, create a config.toml file located in your config directory:

• Linux and Mac: ~/.config/helix/config.toml
• Windows: %AppData%\helix\config.toml

💡 You can easily open the config file by typing :config-open within Helix normal mode.

Example config:

theme = "onedark"

[editor]
line-number = "relative"
mouse = false

[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"

[editor.file-picker]
hidden = false

You can use a custom configuration file by specifying it with the -c or --config command line argument, for example hx -c path/to/custom-config.toml. Additionally, you can reload the configuration file by sending the USR1 signal to the Helix process on Unix operating systems, such as by using the command pkill -USR1 hx.

Finally, you can have a config.toml local to a project by putting it under a .helix directory in your repository. Its settings will be merged with the configuration directory config.toml and the built-in configuration.
