# Config Files

## Boot options

One use of a config file is to set boot flags to execute without having to state them when launching the program.

- This is set under the `[flags]` section.
- These options are generally the same as the long names as other flags (ex: `case_sensitive = true`).
- Note that if a flag and an option conflict, the flag has higher precedence (ex: if the `-c` and `temperature_type = kelvin` both exist, the Celsius temperature type is ultimately chosen).
- For temperature type, use `temperature_type = "kelvin|k|celsius|c|fahrenheit|f"`.
- For default widgets, use `default_widget = "cpu_default|memory_default|disk_default|temperature_default|network_default|process_default"`.

## Colours

Another use is to set colours, under the `[colors]`. The following labels are customizable with strings that are hex colours, RGB colours, or specific named colours.

Supported named colours are one of the following: `Reset, Black, Red, Green, Yellow, Blue, Magenta, Cyan, Gray, DarkGray, LightRed, LightGreen, LightYellow, LightBlue, LightMagenta, LightCyan, White`

| TX                              | The colour tx will use                         | `tx_color="#111111"`                                   |
| Widget title colour             | The colour of the label each widget has        | `widget_title_color="#ffffff"`                         |

Note some colours may not be compatible with the terminal you are using. For example, macOS's default Terminal does not play nice with many colours.

## Default config locations

bottom will check specific locations by default for a config file.

- For Unix-based systems: `$HOME/.config/bottom/bottom.toml`.
- For Windows: `{FOLDERID_RoamingAppData}\bottom\bottom.toml` (for example, `C:\Users\Clement\AppData\Roaming\bottom\bottom.toml`).
