Manipulating text in tab names

[j-xella]

There is :TabRename command which allows setting tab name.

What if I want to revert back to the default behaviour for the tab, showing current file? Is there a way to do this? I tried calling TabRename without arguments, but it is not allowed.

And what if I want to display both, tab name and current file name? Is that possible?

I am new to tabby, using preset tab_only

I think clearing tab name is a missing feature, I want to add it in the next version.

Yes, it's possible:

1. set name_fallback to empty
2. add current window's name to tab label.

Follow the example in Readme, you can set tabline as this:

require('tabby.tabline').set(function(line)
  return {
    {
      { '  ', hl = theme.head },
      line.sep('', theme.head, theme.fill),
    },
    line.tabs().foreach(function(tab)
      local hl = tab.is_current() and theme.current_tab or theme.tab
      return {
        line.sep('', hl, theme.fill),
        tab.is_current() and '' or '',
        tab.name(),
        tab.current_win().buf_name(),
        tab.current_win().name()
        tab.close_btn(''),
        line.sep('', hl, theme.fill),
        hl = hl,
        margin = ' ',
      }
    end),
    line.spacer(),
    line.wins_in_tab(line.api.get_current_tab()).foreach(function(win)
      return {
        line.sep('', theme.win, theme.fill),
        win.is_current() and '' or '',
        win.buf_name(),
        line.sep('', theme.win, theme.fill),
        hl = theme.win,
        margin = ' ',
      }
    end),
    {
      line.sep('', theme.tail, theme.fill),
      { '  ', hl = theme.tail },
    },
    hl = theme.fill,
  }
end, {
  tab_name = {
    name_fallback = function()
      return ''
    end,
  },
})
