Is it possible to have syntax highlighting in cdb/windbg?

I am experimenting with command line debuggers on windows and I was wondering if there’s a way to have syntax highlighting in either cdb or the windbg console?

Solution

  • since you tagged windbg and have windbg in title this answer is for windbg only

    i presume that you are aware windbg is gui and cdb is console application

    windbg src window supports syntax highlighting and provides some options to change the colors and you can dock it side by side

    cdb does not support color unless you are a magician

    magic recipe for magicians that can run colored cdb

    ( it is mentioned that you can create a tools.ini file
    create two entries col_mode: TRUE , col: srcchar R--
    but there is a caveat that this only works in true console
    I don't know if cmd.exe is true console or false console
    I could never coax it to output in color except for .printf /D with dml )

    Regarding the comment where to put tools.ini one can put tools.ini anywhere one wishes just has to make sure the environment variable INIT points to the directory where one has put it

    in the example below i have tools.ini in the debugee directory or current working Directory denoted with .\ and .\tools.ini and i am setting the ENV VAR init to .\ viz current directory

    here is a screenshot for windbg srcwindow with syntax highlighted src

    followed by a colored cmd.exe dml .printf output

    enter image description here

    as you can see the .symopt+10 has been enabled from tools.ini

    so cdb has parsed and understood the color entires

    but single stepping doesn't get color
