Usage

Command line usage

If you have a .flo configuration file (See .flo configuration file), in your current working directory and/or your home directory, flo will parse your configuration file(s) and generate CLI commands for you. To list out the possible commands, use

flo help

You can also see the usage and options for specific commands:

flo help <command>

Ruby script usage

Flo has been built with the intention of being easy to use within ruby scripts. Flo::Runner is responsible for parsing your custom configuration and invoking the commands. See the following example:

require 'flo'

runner = Flo::Runner.new

# Load your custom command configurations (see .flo file section for more details)
runner.load_config_file(File.join(__dir__,'.flo'))

# Run the something:useful command defined in the .flo file
response = runner.execute('something:useful', id: '123')

.flo configuration file

Flo makes very few assumptions about what you want to use it for, or how you want to use it. In order for you to use it for anything useful, you will need to provide it some configuration. This is accomplished by loading one or more .flo configuration files. See Ruby script usage for an example of how to load the file. The .flo file is evaluated in ruby in a cleanroom environment (see the cleanroom gem for more information), so you can require any gems or modules needed to accomplish the functionality you are looking for. There are two required sections:

• configuration
• command registration

Configuration

Before you can do anything useful in your .flo file, you have to declare providers. You can do so using a config block, for example:

config do |cfg|
  cfg.provider :developer, {configuration_option: 'value' }
end

Command registration

You can register any number of commands. Commands are namespaced to make it easier to group together similar commands. Within a command declaration you declare a set of tasks that will be executed in order when the command is invoked. Here is an overly simple example for starting a feature branch that only uses a single provider. In typical usage you would likely utilize multiple providers within a single command.

# Registers a command for starting a feature - feature:start.  This command has
# one required argument: 'feature_name'.  Note that in order for this to work,
# you will need to declare the git_flo provider in the config section.
register_command('feature:start') do |feature_name: nil|

  # During command execution, perform the :check_out_or_create_branch method on
  # the git_flo provider, passing in the :from and :name arguments
  perform :git_flo, :check_out_or_create_branch, { from: 'master', name: feature_name }
end
