Here's our take.

Handwritten Lexers

Nice Pick

Developers should learn handwritten lexers when building compilers, interpreters, or parsers for custom languages, as they provide better performance and flexibility than generated lexers in scenarios with intricate syntax or performance-critical applications

Pros

• They are particularly useful for embedded systems, domain-specific languages, or when integrating with existing codebases where automated tools might not suffice
• Related to: parsing, compiler-design

Cons

• Specific tradeoffs depend on your use case

Parser Generators

Developers should learn and use parser generators when building applications that require parsing structured text, such as programming language compilers, interpreters, domain-specific languages (DSLs), configuration file readers, or data format validators (e

Pros

• Related to: context-free-grammar, lexical-analysis

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Handwritten Lexers is a concept while Parser Generators is a tool. We picked Handwritten Lexers based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Handwritten Lexers wins

Based on overall popularity. Handwritten Lexers is more widely used, but Parser Generators excels in its own space.
