module Thor::Util
def camel_case(str)
String
==== Returns
String
==== Parameters
Receives a string and convert it to camel case. camel_case returns CamelCase.
def camel_case(str) return str if str !~ /_/ && str =~ /[A-Z]+.*/ str.split('_').map { |i| i.capitalize }.join end
def escape_globs(path)
String
==== Returns
String
==== Parameters
Thor::Util.escape_globs('[apps]') # => '\[apps\]'
==== Examples
The glob characters are `* ? { } [ ]`.
Returns a string that has had any glob characters escaped.
def escape_globs(path) path.to_s.gsub(/[*?{}\[\]]/, '\\\\\\&') end
def find_by_namespace(namespace)
namespace
==== Parameters
Receives a namespace and search for it in the Thor::Base subclasses.
def find_by_namespace(namespace) namespace = "default#{namespace}" if namespace.empty? || namespace =~ /^:/ Thor::Base.subclasses.detect { |klass| klass.namespace == namespace } end
def find_class_and_command_by_namespace(namespace, fallback = true)
namespace
==== Parameters
Thor::Util.namespace_to_thor_class("foo:bar:baz") #=> Foo::Bar, "baz"
Thor::Util.namespace_to_thor_class("baz:foo") #=> Baz::Foo, nil
Thor::Util.namespace_to_thor_class("foo:bar") #=> Foo::Bar, nil # will invoke default command
end
class Baz::Foo < Thor::Group
end
end
def baz
class Foo::Bar < Thor

again. If found, returns the highest entry as the class name.
if it's not found, removes the highest entry and searches for the class
from it. It first searches for a class using the all the given namespace,
Receives a namespace and tries to retrieve a Thor or Thor::Group class
def find_class_and_command_by_namespace(namespace, fallback = true) if namespace.include?(':') # look for a namespaced command pieces = namespace.split(':') command = pieces.pop klass = Thor::Util.find_by_namespace(pieces.join(':')) end unless klass # look for a Thor::Group with the right name klass, command = Thor::Util.find_by_namespace(namespace), nil end if !klass && fallback # try a command in the default namespace command = namespace klass = Thor::Util.find_by_namespace('') end [klass, command] end
def globs_for(path)
Where to look for Thor files.
def globs_for(path) path = escape_globs(path) ["#{path}/Thorfile", "#{path}/*.thor", "#{path}/tasks/*.thor", "#{path}/lib/tasks/*.thor"] end
def load_thorfile(path, content = nil, debug = false)
inside the sandbox to avoid namespacing conflicts.
Receives a path and load the thor file in the path. The file is evaluated
def load_thorfile(path, content = nil, debug = false) content ||= File.binread(path) begin Thor::Sandbox.class_eval(content, path) rescue StandardError => e $stderr.puts("WARNING: unable to load thorfile #{path.inspect}: #{e.message}") if debug $stderr.puts(*e.backtrace) else $stderr.puts(e.backtrace.first) end end end
def namespace_from_thor_class(constant)
String:: If we receive Foo::Bar::Baz it returns "foo:bar:baz"
==== Returns
constant
def namespace_from_thor_class(constant) constant = constant.to_s.gsub(/^Thor::Sandbox::/, '') constant = snake_case(constant).squeeze(':') constant end
def namespaces_in_content(contents, file = __FILE__)
Array[Object]
==== Returns
contents
==== Parameters
namespaces defined in the sandbox.
Given the contents, evaluate it inside the sandbox and returns the

def snake_case(str)
String
==== Returns
String
==== Parameters
Receives a string and convert it to snake case. SnakeCase returns snake_case.
def snake_case(str) return str.downcase if str =~ /^[A-Z_]+$/ str.gsub(/\B[A-Z]/, '_\&').squeeze('_') =~ /_*(.*)/ $+.downcase end
def thor_classes_in(klass)
Returns the thor classes declared inside the given class.

def thor_root
Returns the root where thor files are located, depending on the OS.
def thor_root File.join(user_home, '.thor').gsub(/\\/, '/') end
def thor_root_glob
If we don't #gsub the \ character, Dir.glob will fail.
C:\Documents and Settings\james\.thor
like this:
Returns the files in the thor root. On Windows thor_root will be something
def thor_root_glob files = Dir["#{escape_globs(thor_root)}/*"] files.map! do |file| File.directory?(file) ? File.join(file, 'main.thor') : file end end
