UPDATE TWO:
All my concerns and doubts in this post seem to be solved!
Original, not modified, versions of NP++ come with style for JavaScript/“operator” set to black/bold. Surprisingly that makes all braces/brackets bold by default! One has to remove that original bold setting to have that match check shown with black/bold.
It seems there is no way to set a full even background color for a language, except when it is embedded. JS (embedded) can be set, PHP too, actualy PHP is always embedded between <?php ?> tags, even if there is nothing else outside the tags. Contents of a JS file isn;t embedded when you check it by itself.
I had the wrong impresion code of a JS file was shown in a light blue tint for the background, actually it has a white background (I would like to see it as it is when embedded, though!).
Finally
3. If one makes a new installation in a fresh folder and copy config.xml from another installation, this config.xml carries a line like
<GUIConfig name=“stylerTheme” path=“C:\ …\np++previous\stylers.xml” />
and previous stylers.xml continue to be used in the fresh new installation.
So now everything is working basically well for me, I 'm happy, and very thankful to Meta Chu for the quick start.
But I’ll be back. We need a better way to use sessions than having several installations ( or having to save/load sessions files all the time ).
Thank you for the attention.
