[-refresh within script block does not work]

Thanks for your detail! Now the situation I encounter is clear.

And thanks for your workaround too.

I tried to use function start-gadget { xxx } instead of your idea, however it does not work.

So, set/get-content is the best I think.

[-refresh within script block does not work]

What I am trying to do is in your reference link. []

I use start-demo function mentioned in that blog post to automate demo. Start-demo reads one-liners from text file and invoke them line by line. As written in the post, it invokes command line like following,

Invoke-Expression $(".{" + $_lines[$_i] + "}| out-host")

$_lines holds one-liners read from text file.

When I added 'get-date|out-gauge -refresh 0:0:1' to my demo commands for example, out-gauge shows error I wrote earlier. Out-gauge was invoked as

.{ get-date | out-gauge -refresh 0:0:1 } | out-host

While following invokes out-gauge -refresh without error.

Invoke-Expression $(".{`n" + $_lines[$_i] + "}| out-host")

Actual lines would be

{

get-date | out-gauge -refresh 0:0:1 } | out-host

 

[-refresh within script block does not work]

When I tried this script,

&{get-date | out-gauge -refresh 0:0:1}

An error icon appears on the gauge which says closing "}" is missing.

I guess out-gauge captures commands before pipe so that error would be reasonable.

Any workaround to use refreshing commands within a single line script block?
