P/telekasten_show_current_vault

It seems like the telekasten picker does not know the existing vault so there is no variable around it. It changes the current settings based on the configuration of each vault.

https://github.com/renerocksai/telekasten.nvim/blob/main/lua/telekasten/pickers.lua

However current home value can be used as a proxy

local function currenthome()
  local home = require('telekasten').Cfg.home
  if home == "/path/to/default" then return "default" end
  if home == "/path/to/alternative" then return "alternative" end
  end

and then call the function in the statusline configuration. E.g.: lualine:

require('lualine').setup {
  options = {
    ...
    },
  sections = {
    ...
    lualine_x = { {currenthome}, 'filetype'},
    ...
  }
}
