[Feature Request] Add --verbose option

Hi @carloscuesta!

I love gitmoji and gitmoji-cli. Thank you for making it happen.

I have my own pre-commit hook that makes changes to files and messages the user in the process, so that there’s a record and some awareness of what’s changed.

I’ll admit the way I do it is a bit hacky; I know R far better than I know bash, so I have the pre-commit hook call R to run a script. But it gets the job done, and it also messages the user about it.

That is to say, when I use a simple git commit it messages the user. But when I use gitmoji-cli -c, there is no messaging.

I think maybe the messaging ends up in stderr. For example, I tested what would happen if I had my pre-commit hook always exit with non-zero status. I learned via that test that at least the hook was working… but I also saw my R messaging come through in stderr. But when I changed it to exit successfully, alas, I lost my messaging.

Is there a way to get that back? As I suggested in the title, maybe a --verbose or -v option?

From a quick look into it, execa support to disable the output buffer, to stream the process, tested in a quick POC, adding thoses options seems to do the trick (redirecting the stdout stream to the current process, might need a more careful approach with stdin):

I will probably create a execa wrapper with the correct options for usage within gitmoji-cli when we want to display stdout (hook and commit modes)

[Jeremie-Chauvel]

basically:

const { stdout } = await execa(
      'git',
      ['commit', ...isSigned, '-m', title, '-m', answers.message],
      { buffer: false, stdio: [process.stdin, process.stdout, process.stderr] }
    )
