Outputting HTML in a PowerShell notebook 
¶
The magic of the Out-Display cmdlet¶
Displaying rich output¶
If you want to write out a string as HTML, you can use the Out-Display cmdlet:
In [ ]:
'<b style="color:blue">Hello!</b>' | Out-Display
Specifying a MIME type¶
Out-Display also allows you to specify the MIME type which gives you the ability to:
In [ ]:
# Output JavaScript
Out-Display "alert('Hello!');" -MimeType application/javascript
# Output Markdown
Out-Display "**BOLD** _ITALICS_" -MimeType text/markdown
Specifying a custom MIME type¶
If you want to use your own MIME type on one not defined in -MimeType you can use the -CustomMimeType parameter:
In [ ]:
Invoke-WebRequest https://raw.githubusercontent.com/PowerShell/PowerShell/master/assets/avatar_128.svg |
Select-Object -ExpandProperty Content |
Out-Display -CustomMimeType 'image/svg+xml'
