Problem with %_FG and %_BG

[dcantor]

I'm trying to save the current colors, change them temporarily, and change them back, using something like this:

set savecolors=%_fg on %_bg
color  (something else)
(do some stuff)
color %savecolors

This always produces white on black.

Here's a test:

C:\Tv\TV_DATA\Groton> ver

TCC  12.11.69   Windows XP [Version 5.1.2600]

C:\Tv\TV_DATA\Groton> color bri white on green

C:\Tv\TV_DATA\Groton> echo %_fg on %_bg
Whi on Bla

My workaround for now is that I can restore to standard colors, rather than what was current at the time I save them, with

set savecolors=%@format[02,%@eval[%@option[StdColors]=h]]

but what I really want is a way to save and restore the current colors.

As I understand it, those two variables report the colors at the cursor position. In most cases, they will be white on black -- unless you have filled the screen buffer with something else via e.g. CLS BRI WHI ON GRE.

A variable or variables reporting the color TCC will use for stdout might be useful; but I don't think that's what _FG and _BG do.

Ah, I see.

Rex, would you consider a way to read out the current values of the foreground and background colors as set by COLOR?
