When writing a PowerShell script or function, things like indentations, white space and case make a big difference in how easy it is to read and understand your code. Sometimes it can be helpful to have a word or sentence in all upper case so that it stands out. Here is a simple set of commands you can insert into your PowerShell ISE profile to convert selected text to all upper or lower case.<\/p>\n
The concept is incredibly easy. I trust you know that a string object has method called ToUpper().<\/p>\n
[cc lang=\"Powershell\"]
\nPS C:\\> $s=\"abcdefg\"
\nPS C:\\> $s.toUpper()
\nABCDEFG
\n[\/cc]<\/p>\n
The method doesn't change the value of $s, merely returns an uppercase version. There is also a corresponding ToLower() method. In the ISE, we can use the object model to reference any selected text using<\/p>\n
[cc lang=\"Powershell\"]
\n$psise.CurrentFile.Editor.SelectedText
\n[\/cc]<\/p>\n
This will be a string object which means we can call the ToUpper() and toLower() methods.<\/p>\n
[cc lang=\"PowerShell\"]
\n$psise.CurrentFile.Editor.SelectedText.toUpper()
\n[\/cc]<\/p>\n
But what do we do with the result? We can insert it back into the file using the ISE object model.<\/p>\n
[cc lang=\"PowerShell\"]
\n$psise.currentfile.editor.insertText($psise.CurrentFile.Editor.SelectedText.toUpper())
\n[\/cc]<\/p>\n
Knowing this, I added two lines to my ISE profile script to append a couple of items to the AddOns menu.<\/p>\n
[cc lang=\"PowerShell\"]
\n$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add(\"Convert to uppercase\",
\n{$psise.currentfile.editor.insertText($psise.CurrentFile.Editor.SelectedText.toUpper())},\"CTRL+ALT+U\") | Out-Null
\n$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add(\"Convert to lowercase\",
\n{$psise.currentfile.editor.insertText($psise.CurrentFile.Editor.SelectedText.toLower())},\"CTRL+ALT+L\") | Out-Null
\n[\/cc]<\/p>\n
In the ISE you can run psedit $profile to edit. On my menu I now have two additional options, \"Convert to uppercase\" and \"Convert to lowercase\" with the corresponding keyboard shortcuts. If you don't want any shortcuts use $Null.<\/p>\n
