NPrint colour output

[LessNick]

Hello AGAin o/

Is it possible to set color for ouput with NPrint (CLI)?

I search a lot of documentation, forum & google
But the only mention is the colour command.

As I understand it, it is used to select a color for working with bitmap olny.

I try use CLI escrape trick with echo like "*e[", but it looks like this is only used by the echo command itself.

Perhaps there is an option to use ESC sequence like CHR$(27) + codes

But honestly I haven't found anything similar.

If you are using a window you could try with WColour command

Indeed, this is used for writing characters directly to a bitmap.

Yep, typically NPrint will simply directly output whatever characters are in the quotes and no interpretation is done. The escape codes are interpreted by the console, but it's difficult to enter the ASCII characters directly for use by Echo etc., which is why the special sequence is required.

That should actually work, since you're then presenting the escape character directly to the console to interpret. For example:

NPrint Chr$(27), "[1mHello Bold World!"

should print the phrase in bold. It's a little clumsy though, so perhaps having some preset formatting strings might be better if you're going to be doing a lot of formatting?

bold$ = Chr$(27) + "[1m"
italic$ = Chr$(27) + "[3m"
nobold$ = Chr$(27) + "[22m"
highlight$ = Chr$(27) + "[33m"

; Rest of your program here

NPrint bold$, "Bold", italic$, " Bold-Italic", nobold$, highlight$, " Highlighted italic"
End

Thanks a lot! This is exactly what I was looking for.

Thank you very much for the clarification, now it has become a little clearer.

Fun fact though. If you output all this to the console that BlitzBasic itself opens, everything works ok:



But if use the NoCli command and open an own Window, then NPrint show a square(unknown symbol code 27), and then [1m

Yep, that's to be expected. The difference is that the console window is effectively text-based, and it's the console that interprets the escape codes, not the actual window. You can only really interact with it in terms of text. If you open your own window, it's essentially a blank graphics object, not a text window like the console, so it behaves more like a bitmap.
