How Domain Experts Use an Embedded DSL
summary
An embedded DSL called Mimi targets climate-economics models and the paper reports a contextual inquiry with 9 participants; designers use Julia features like custom types and macros and integrate with the package system. Findings show the embedding causes unexpected pain: formatters break macro parsing, help lookups confuse users, and novices struggle when host and DSL blur. Users overwhelmingly turn to eDSL-specific forums and reuse provided code templates, which drives adoption and shapes API evolution.
