ColorThis

Tell the program I just want you to print the color.

Quick start

Prerequisites

the compile depends is

cmake make gcc

no runtime depends

Installation

  1. Download ColorThis use git clone [email protected]:Sasasu/ColorThis.git
  2. Compile
cmake -DCMAKE_INSTALL_PREFIX=/usr .
make
sudo make install

Usage

type ColorThis in your terminal, you will get like this

$ ColorThis
Usage: ColorThis <option> [application]
where options are
        -stdin:   make stdin is a tty
        -stdout:  make stdout is a tty
        -stderr:  make stderr is a tty
        -hook:    hook libc's isatty function
                  NOTE: may not work well
where application like
                  ls / </dev/null 2>/dev/null

this command shows full function

$ ColorThis -stdin -stdout -stderr $SOME_FRIENDLLY_GO_APP $COMMAND 2> colorfull_err_log.log < input_from_terminal.txt | tee colorfull_log.log

How it works

if -hook is enabled, ColorThis will inject self to LD_PRELOAD and patch isatty function in libc.

but if the application call syscall directly or is fully static link this method will not work.

if -hook is not enabled, ColorThis will creat at most 3 ptys, catch all signs, creat a new session, fork and exec the new executable file.

ColorThis act like a terminal, exec the new executable file then attach some new tty to this session, these tty forward anything to the real tty.
