🔗 How Erlang's parser tools saved my DSMR library

Have you ever been buried under a maze of regex and string operations? Robin van der Vleuten shares how he faced this dilemma while working on a DSMR library for smart meter data. Initially relying on chaotic regex patterns, van der Vleuten struggled with parsing errors and maintenance challenges. The breakthrough came when he discovered Erlang's leex and yecc.

These tools allowed him to define clear patterns and grammar rules, transforming the parsing process into a more declarative approach. By separating concerns, enhancing error reporting, and improving performance, these parser tools not only streamlined his library but also reminded him of the value of established solutions in programming.

The library is now open source and effectively handles various DSMR versions and smart meter types, embodying the lesson that sometimes older tools are the best fit for complex tasks.
