It would be nice to be able to specify fg/bg colors at the tty level, so that echoed characters can be colorized. Then your shell can arrange that shell command input is one fg/bg color, and other input taken by commands run from the shell is another color. For example, like this: stty color-echo=#ffdddd/#000022 color-out=#ddffdd color-err=/#220000 stty color-fd3=/#222255 stty color-out= or stty color-type=cmd:#ffdddd/#000000 stty color-echo=cmd echo foo stty color-echo=#eeeeee echo bar stty color-echo=cmd echo baz Names of things that can be colorized might include: echo out err fd0 fd1 fd2 ... I think named colors should be supported, with at least these builtin names: echo-default in-default out-default This stty color-type=echo-default: tells the tty driver that echo-default does no colorizing. I used #xxxxxx notation as a placeholder. Probably in actual use, the user would supply a terminal escape sequence. Typeahead is tricky: stty color-typeahead=#ff6666/004444 This would cause typeahead to be echoed in the desired color, and then when appropriate, typeahead characters could change color, such as when they are consumed or when they are hanging there with a pending cooked read. >Release-Note: >Audit-Trail: >Unformatted:
