An experimental status line display has now been hooked up to the "newquery$" word which is compiled from library during yoda launch.
The status line may look like this:

yoda version 0.5.7 flags:fIs base:10 depth:3 rdepth:0 files:17 unresolved:0 bits:63 6 20 -5

The possibly more obscure item on statusline are described in the following rundown of its components:

• yoda version 0.5.7
  • evident, supposedly
• flags:fIs
  • enable/disable state of forwardsrefs, instant resolving and shell.
  • Capitals represent enabled, lowercase letters indicate disabled.
  • change state of forward references with with +f -f
  • change state of instant resolving with with +i -i
  • change state of shell with with +s -s
• base:10
  • evident
• depth:3
  • count of items on stack
• rdepth:0
  • count of items on return stack
• files:17
  • count of included files
  • see by executing files
• unresolved:0
  • unresolved words count
  • see by executing .unresolved or words
• bits:63
  • width of an integer in bits.
  • Set in yoda.conf
• 6 20 -5
  • A stack dump of the top max 9 items.
  • Respects base, so status line may become too long for a single line with binary numbers or lots of large numbers with different radix.
