Hi @Pavankumar07s ,

Yeah, feel free to send a PR, no need to ask for permission :) One thing to keep in mind would be to introduce a --no-color option, and potentially also check if you are running on a TTY or not, and disable color automatically!

Hi @jviotti,

Just wanted to share a quick update on my progress:

1.Codebase Review: I've thoroughly reviewed the existing codebase.
2.Terminal Detection: I've implemented a mechanism to detect if the program is running in a terminal using #include <unistd.h>.
3.Colored Output: I've successfully implemented colored output for messages.
4.User Preference: I've added an option for users to toggle colored output on or off.
It would be great help to guide me for some further steps .
I am attaching some pic have a look.Going to more parts of code.Thankyou.

Hi @Pavankumar07s , great progress! I recommend trying to break down the work into as many small PRs as possible, so they are easier to review and polish. One potential way would be to:

• Create a first PR that introduce the <unistd.h> approach on a helper in utils.h/utils.cc and maybe just uses it to color code "JSON Schema CLI vX.Y.Z" on the help page. Something super simple and without letting users control it yet
• Once we have that merged, you can add support for the --no-color switch, and take of documenting it everywhere, etc
• Once that is merged, you can send a PR for each command that you want to augment with colouring
