System-wide highlighting rules?

[aybe]

So, I did the following:

Then, for the scheme to always apply, one must do the following:

• save the .hexproj project
• always open a file within this project

Was wondering if there could be system-wide highlighting rules so that one doesn't have to do this every time?

Thanks!

Why did you decide to use highlighting rules to set the colors? If you want to define a way to color many files using one set of rules then a pattern seems more appropriate.

to have many files colored the same way they would have to be in the same project and they cannot have rules of their own that conflicts with the main one.Otherwise you would need to re-create the rules because the rules cannot be imported and/or exported.

I did this because, as I understand, patterns need structured data, i.e. the logic of a real file format.

Or maybe I didn't understand how patterns really work...

Formats are what the pattern language was designed to help describe. That's not to say that every pattern one can write has to be a real format. For example u8 a =0; is a valid pattern file. Highlighting rules are not easy to share among input files but patterns are. One possible pattern follows.

import std.mem;

u32 colorCount = 13;

str Colors[colorCount] = {"A02020", "A08020", "A0A020", "80A020",
                                        "20A020", "20A080", "2080A0", "20A0A0",
                                        "2020A0", "8020A0", "A020A0", "A040A0", "A080A0"};

struct Color {
    u8 value;
}[[color(Colors[value/20])]];

Color color[while(!std::mem::eof())]@0;

Very interesting to see how you abused the system, thanks! 😅

I realize that dividing by 20 is just an approximation to your choice of values for each color and the fact that you define 12 colors while i define 13. I wasn't looking to match your code exactly, just a proof of concept to show that it is easier to implement the rules in pattern language than using the highlighting rules. If you don't want to populate the pattern data window make the Color struct hidden.

Yes, it's OK, I'll just keep digging using your approach, thanks!

I would also like this feature.

The first clearly shows the structure of the file I am looking at. The second shows the value of the hex bytes. I would like the benefits of both:
