There are numerous possible way of categorizing the entities and concepts that
|
|
make up a programming language. Ruby has a fairly large number of reserved
|
|
words. These words significantly describe major elements of the language,
|
|
including flow control constructs like 'for' and 'while', conditional
|
|
execution like 'if' and 'unless', exceptional execution control like 'rescue',
|
|
etc. There are also literals for the basic "types" like String, Regexp, Array
|
|
and Fixnum.
|
|
|
|
Behavorial specifications describe the behavior of concrete entities. Rather
|
|
than using concepts of computation to organize these spec files, we use
|
|
entities of the Ruby language. Consider looking at any syntactic element of a
|
|
Ruby program. With (almost) no ambiguity, one can identify it as a literal,
|
|
reserved word, variable, etc. There is a spec file that corresponds to each
|
|
literal construct and most reserved words, with the exceptions noted below.
|
|
There are also several files that are more difficult to classify: all
|
|
predefined variables, constants, and objects (predefined_spec.rb), the
|
|
precedence of all operators (precedence_spec.rb), the behavior of assignment
|
|
to variables (variables_spec.rb), the behavior of subprocess execution
|
|
(execution_spec.rb), the behavior of the raise method as it impacts the
|
|
execution of a Ruby program (raise_spec.rb), and the block entities like
|
|
'begin', 'do', ' { ... }' (block_spec.rb).
|
|
|
|
Several reserved words and other entities are combined with the primary
|
|
reserved word or entity to which they are related:
|
|
|
|
false, true, nil, self predefined_spec.rb
|
|
in for_spec.rb
|
|
then, elsif if_spec.rb
|
|
when case_spec.rb
|
|
catch throw_spec.rb
