Make fastlane less verbose

Question

Is there a way to configure (may be using the Fastfile, for example) or execute Fastlane in a less verbose way?

It currently prints a lot of information that generally blinds developers of warnings and also errors. The main problem is that it takes some time scrolling and searching for the yellow/red text among a lot of useless messages until you have a clue of what happened.

The default setup prints everything and surprisingly there is even a --verbose mode for the CLI, but I could not find anything that do the opposite, like for example a --quiet mode.

EDIT:

Bellow are some examples of output I would like to be able to suppress. Taking into account that I use a Fastfile from a git repo, gym, match, cocoapods, get_version_number, increment_version_number and several other actions

• Installed Provisioning Profile table
• All git clone and related from remote Fastfile download
• get_version_number and increment_version_number detailed outputs
• legacy build system info message
• All detailed outputs like match's "Cloning remote git repo..", "Successfully decrypted certificates repo", etc
• gym, match, fastlane and all other summaries printed
• All release notes from more up-to-date versions for match, gym and fastlane itself

Answer 1

Did you check the fastlane documentation at https://docs.fastlane.tools/actions/? For some of them there are parameters to surpress output, for gym:

gym(
  ...
  silent: true,
  suppress_xcode_output: true,
  ...
)

Answer 2

What are some examples of what you want to hide from the output? If you're talking about the xcodebuild output, it's being piped over to xcpretty, which does the rendering of the source files.
