@B-M ,
I was actually cogitating over this for the past day, because I thought a simplified version of your request might be doable in a scripting plugin:
If you are willing to use a script for the PythonScript plugin and run it manually, then this might be enough for you.
23883-highlight-frequent-words.py
PythonScript Instructions
When you run the script, it will analyze the active file’s wordlist, and assign a foreground color to the N most-frequent words from the active file. (It will ignore 1 and 2-letter words, and anything in the list of stopwords. The default stopwords include some linking verbs, conjunctions, articles, and prepositions; there are probably other words that should be in the default list, but it was enough for proof-of-concept.)
You can edit the script to change the “stopwords” by adding words into the string. You can change the palette by editing the list in def createPalette(): , and by doing that, you can change how many words will be colored.
The 2022-Dec-13 source for the script is included in the post. The link above will always take you to my most recent version (in case I make future bugfixes or feature additions).
Script
# encoding=utf-8
"""in response to https://community.notepad-plus-plus.org/topic/23883/
When run, this script will count all the words (except for stopwords),
and assign a color to each word in the list of Top N Colors
Edit the contents of the stopwords variable to change which words are ignored
- the default stopwords are some linking verbs, conjunctions, articles, and prepositions
- words of 1 or two characters are automatically annoyed
Edit the list of appended colors in createPalette() to change the color palette
- you can change the colors to your liking
- you can add or remove colors to change the number of words that will be colored
- the default color list is based on mspaint.exe's palette on my laptop
Based heavily on these:
