Simple colored output helper for ruby scripts.
# ~/some_ruby_script.rb
require 'fiedl/log'
log.head "Awesome script"
log.section "Checking dependencies"
log.info "Checking if all dependencies are met."
log.success "Ok"
log.section "Checking deprecations"
log.warning "This does not work much longer ..."
log.section "Checking other stuff"
log.error "This script does nothing, yet."
raise "This script does nothing, yet, sorry!"
This gem defines log
unless log
is already defined. But, of course, you may manually instantiate it:
# ~/some_ruby_script.rb
require 'fiedl/log'
$log = Fiedl::Log::Log.new
# ~/some_ruby_script.rb
require 'fiedl/log'
log.filter_out("my_secret_password")
This will filter out any occurance of "my_secret_password" and replace it by "[...]" in the output.
Print a shell command, execute it and display the result:
# ~/some_ruby_script.rb
require 'fiedl/log'
shell "whoami"
The shell
command returns both the output of the stdin and the stderr.
To prevent the shell
command from printing anything, use verbose: false
:
user = shell "whoami", verbose: false
# ~/some_ruby_script.rb
require 'fiedl/log'
foo = "bar"
log.variable foo, "foo"
options = {
foo: 'bar'
}
log.configuration options
Ensure that a certain file is present before continuing: If the file is missing, the error is logged and the script is stopped.
# ~/some_ruby_script.rb
require 'fiedl/log'
log.ensure_file "$HOME/.zshrc"
Add this line to your application's Gemfile:
gem 'fiedl-log'
And then execute:
$ bundle
Or install it yourself as:
$ gem install fiedl-log
