Original Pull Request: https://github.com/microsoft/terminal/pull/14991

State: closed
Merged: Yes

#14745 contains two regressions related to console alias handling:

  • When ProcessAliases expands the backup buffer into (an) aliased
    command(s) it changes the _bytesRead field of COOKED_READ_DATA,
    requiring us to re-read it and reconstruct the input string-view.
  • Multiline aliases are read line-by-line whereas #14745 didn't treat
    them any different from regular single-line inputs.

Validation Steps Performed

In cmd.exe run

doskey test=echo foo$Techo bar$Techo baz
test

The output should look exactly like this:

C:\>doskey test=echo foo$Techo bar$Techo baz

C:\>test
foo

C:\>bar

C:\>baz
