Overview

This class is responsible for checking the ARGV to see if the user wants to launch another fastlane tool or fastlane itself

Class Method Details

.available_lanes ⇒ Object

Returns an array of symbols for the available lanes for the Fastfile This doesn’t actually use the Fastfile parser, but only the available lanes. This way it’s much faster, which is very important in this case, since it will be executed every time one of the tools is launched Use this only if performance is :key:

def available_lanes
  fastfile_path = FastlaneCore::FastlaneFolder.fastfile_path
  return [] if fastfile_path.nil?
  output = `cat #{fastfile_path.shellescape} | grep \"^\s*lane \:\" | awk -F ':' '{print $2}' | awk -F ' ' '{print $1}'`
  return output.strip.split(" ").collect(&:to_sym)
end

.load_dot_env ⇒ Object

Since loading dotenv should respect additional environments passed using –env, we must extrat the arguments out of ARGV and process them before calling into commander. This is required since the ENV must be configured before running any other commands in order to correclty respect variables like FASTLANE_HIDE_CHANGELOG and FASTLANE_DISABLE_COLORS

.process_emojis(tool_name) ⇒ Object

Since fastlane also supports the rocket and biceps emoji as executable we need to map those to the appropriate tools
