DetachDomain(domain)

Since: 20220624-141144-bd1b7c5d

Attempts to detach the specified domain. Detaching a domain causes it to disconnect and remove its set of windows, tabs and panes from the local GUI. Detaching does not cause those panes to close; if or when you later attach to the domain, they'll still be there.

Not every domain supports detaching, and will log an error to the error log/debug overlay.

local wezterm = require 'wezterm'
local act = wezterm.action

return {
  ssh_domains = {
    {
      name = "devhost",
      remote_address = "devhost.example.com",
    }
  },
  keys = {
    {key="U", mods="CTRL|SHIFT", action=act.AttachDomain("devhost")},
    -- Detaches the domain associated with the current pane
    {key="D", mods="CTRL|SHIFT", action=act.DetachDomain("CurrentPaneDomain")},
    -- Detaches the "devhost" domain
    {key="E", mods="CTRL|SHIFT", action=act.DetachDomain{DomainName="devhost"}},
  },
}
