Colors not shown when open code files
-
Hi, I just installed Windows 11 and wanted to install Notepad++ as I use it primarily for code editing (Stata, R, and related). My new Notepad++ installation is not showing colors as were shown before (e.g. with “commenting” I use “*”, which used to turn to green in comparison with other code chunks. How can I restore this old setting? Thanks!

“Stata” isn’t in the Language menu (and never has been), but “R” is, so Notepad++ doesn’t handle Stata by default.
For R, if you open a file that has the extension
.ror.sor.splus, it will apply syntax highlighting. And my quick search claims that R comments are#: Notepad++ highlights# ...as green with the default styler:
As I said, Notepad++ has never made Stata highlighting available. You may have previously used a User Defined Language for Stata.
While Notepad++ doesn’t make Stata available, the underlying Lexilla lexer which Notepad++ uses does have Stata, at least in Notepad++ versions 8.4 and newer. And we discussed in a recent topic that if you are willing to install and use the PythonScript plugin, you can activate one of the “hidden” lexers – that discussion showed how using SAS, but the procedure for Stata should be the same:
You would grab the script that I linked in this post in that discussion, follow the instructions in the How to run a script in PythonScript plugin FAQ for instructions on installing and running the script. Then you would have to edit that script to refer to the STATA constants and keywords rather than the SAS list.
Even better, @Ekopalypse might confirm whether with the addition of NPPM_CREATELEXER in v8.4.3 , it might be easier to implement than the script I showed before.

This script “enable-stata-lexer.py” is an edited version of the script linked earlier, customized for Stata. It probably doesn’t have every keyword (I am not a Stata user, so just hacked together from a few web searches)
The Stata lexer has two keyword lists, so you can only have two individual colors that you specify in the script. It labels them as “words” and as “types”, so I assumed the “words” were meant as keywords, and the “types” as the data types.

Yes, with the newly introduced NPPM_CREATELEXER message we can get rid of the function determining definitions.
So something like this works now.# -*- coding: utf-8 -*- ''' Makes the builtin SAS lexer available for NPP.
