Please take a look at my code for a customized PS prompt below.
I'd like to figure out how to eliminate #2 and only display $pwd
when only whitespace is entered as a command.



And also, this is my first "real" PS code, so comments regarding
technique or even style would be appreciated.

All lines below indented two spaces so wrap can be detected:
Function prompt {
# PS prompt displays $pwd only when either of any of these is true
# #1 current command is just whitespace
# #2 last command is exactly the same as current command
# #3 no commands have yet been entered
# When $pwd is displayed, it displays on a line above the effective PS prompt
#
$h = h
$p = ""
if ($h -eq $null)
{$p = 'PS ' + "$pwd" + "`n"}
else
{
if ( $h[$h.length-1].CommandLine -eq $globalrompt_last_command )
{$p = 'PS ' + "$pwd" + "`n"}
}
$p + 'PS> '
if ($h -eq $null)
{$globalrompt_last_command = ""}
else
{$globalrompt_last_command = $h[$h.length-1].CommandLine}
}

What if you try comparing IDs instead of CommandLines?

Thanks! That substitution makes it work like I wanted it to.
Now, if I want to see the current directory, I just hit the Enter key.
Otherwise, the PS prompt stays minimal.

Function prompt {
# PS prompt displays $pwd only when either
# 1) current command is just whitespace
# 2) no commands have yet been entered
# When $pwd is displayed, it displays on a line above the effective PS prompt
#
$h = Get-History
$p = ""
if ($h -eq $null)
{$p = 'PS ' + "$pwd" + "`n"}
else
{
if ( $h[$h.length-1].Id -eq $globalrompt_last_command_Id )
{$p = 'PS ' + "$pwd" + "`n"}
}
$p + 'PS> '
if ($h -eq $null)
{$globalrompt_last_Id = ""}
else
{$globalrompt_last_command_Id = $h[$h.length-1].Id}
}

By the way, a handy shortcut: you can write $h[-1] instead of
$h[$h.length-1]

Thanks! I've now coded it that way.

I'm also finding that I need to do
$h = (Get-History)
to create an array in the case where there is only one command in the session
history.

And now I find I have to use

$h = @(Get-History)

instead to make sure $h is an array.

Sure! It has evolved some more:

function prompt {
# PS prompt displays $pwd only when last command is cd or Set-Location.
# When $pwd is displayed, it displays on a line above the prompt.
# The host window title always displays $pwd.
#
$host.ui.rawui.WindowTitle = "PS $pwd"
$p = 'PS ' + (([string] $pwd).split('\'))[0] + '> '
if (@(Get-History).count -eq 0) {return $p}
$s = ((Get-History -count 1|Select-Object -expandproperty
commandline).split(' '))[0]
switch ($s) {
'cd' {return "PS $pwd`n" + $p}
'Set-Location' {return "PS $pwd`n" + $p}
default {return $p}
}
}
