How to change tab display width?

[RolandMarchand]

By default, tabs in Helix are two characters wide, I wish to set them to 8 characters wide globally for every language and every mode.

I tried to add this to config.toml and languages.toml, but it has no effect:

indent = { tab-width = 8, unit = "\t" }

Note that I am not asking about using tabs over spaces or vice versa. I only want to change the displayed size of tabs.

Does anyone know?

first, tab width is per-language (there'll soon be a way to import language configs). so you want to use that key ("indent") under the appropriate table of your language(s)

For Hare

[[language]]
name = "hare"
indent = {tab-width=8, unit="\t"}

see the docs for me details
