Stop Torturing Your Colleagues with DSLs

The article critiques the use of Domain-Specific Languages (DSLs) in programming, arguing that they often complicate rather than simplify development processes. While DSLs may seem appealing as specialized tools, they typically create significant challenges, including steep learning curves, maintenance difficulties, and communication barriers. The author emphasizes that only a few developers, those who created the DSL, can effectively navigate these languages, leaving others stranded with complex and poorly designed systems. Furthermore, the departure of DSL creators can lead to a loss of crucial knowledge, exacerbating the issues for remaining team members. Instead of creating a new DSL, the author suggests that developers should consider using well-designed libraries, which can provide similar functionality without the associated costs of learning and maintenance. Libraries built on general-purpose languages also benefit from broader community support, making them more accessible and efficient. The article concludes with a call for developers to reconsider the necessity of DSLs and to prioritize practical, straightforward solutions that do not burden their colleagues.

- Domain-Specific Languages (DSLs) often complicate development rather than simplify it.

- Only a few developers can effectively use DSLs, leading to knowledge gaps when creators leave.

- Well-designed libraries can provide similar functionality without the steep learning curve of DSLs.

- Libraries benefit from community support, making them more efficient and accessible.

- Developers should critically assess the need for DSLs before creating them.
