The content discusses the implementation of a pipeline operator in Ruby, inspired by similar features in other languages like Elixir. The pipeline operator allows for cleaner code through a series of clearly visible data processing steps. Although there have been numerous proposals to integrate this feature into Ruby, skepticism arises due to the differences in their APIs—specifically, Elixir's methods belonging to modules, while Ruby's methods belong to objects being processed. Despite attempts to create a pipeline operator in Ruby, including a temporary integration that was

The author revisits the topic of optimizing recursive ascent parsing after initially planning to shift focus to generalized parsing. This new post will build on previous discussions by examining optimizations through the lens of automata, specifically the Push-Down Automaton (PDA), which is closely linked to code implementation. The author aims to illustrate these optimizations using diagrams, focusing on a simple arithmetic grammar that distinguishes between multiplication and addition based on their precedence. The post will showcase the full PDA with stack actions to better understand
