For those of you who don't have Notepad++ yet... should download it right now..
Notepad++ Download
All right, first of all extract the rar file to your Desktop or your any other desired destination.
The rar file contains to xml files, named "MTWII - Script" & "TW_MEDII_SC".
What you have to do now is to copy the "TW_MEDII_SC" into your notepad++ APIs folder. Have a look at the picture below for the exact destination.
So next step is to import the remaining file "MTWII - Script" into your notepad++.
That is how we do it.
Open notepad++, go to languages -> user defined languages and click the import button.
Now navigate to the path of the "MTWII - Script" file and press "open".
If everything goes well, the language should now be displayed as shown in the picture below.
After you have closed and reopened notepad++ go again to languages and tadada! a new script language is now available.
Notes:
Here are two additional notes on adding the language to notepad++.
1. Change the design to "Blackboard" for a more effective contrast.
2. Be sure that you have auto-completion enabled! Settings -> Preferences -> Auto-Completion -> Enable auto-completion.
Otherwise it won't work properly.
