Associate File Extensions With Specific Languages in Notepad++
[ 29 July 2009 ]
Marked under time savers, windows.

If you use Notepad++ often, you may notice that it recognizes the type of file you open and provides nice synatx style for the language of the file. For example, it knows .js is a JavaScript file and .css is a CSS file. Each file type has its own unique style settings. There are a lot of these predefined file types, but what if Notepad++ doens’t support a file type you open often? If you want to make a custom file type use the same style of another type, just use the Style Configurator to define your own extensions.

Add Custom User Extensions

In Notepad++ navigate to Settings > Style Configurator…

Choose a language on the left side that you want your own extension to match (i.e. if I want .config files to style like XML then I’d choose XML). In the User ext. field near the bottom, enter in your custom user extension without the dot in front of it (e.g. config for *.config files). Now restart Notepad++ and it will map that new extension to the style you’ve chosen.
