Unlike these prepackaged generators, you remain in
control, and so can ?¬?x the problem??”on your timetable rather than when it happens to
suit the vendor. DSM generators also solve the problems of the ???sausage factory???
generators, which churn out multiple similar blocks of boilerplate code to be hand
edited. Unlike those, a DSM generator can later be changed and all code regenerated:
the equivalent of changing your recipe and having all sausages already delivered to
shops update automatically!
For most developers, one of the hardest tasks in Domain-Speci?¬?c Modeling is to
not build the generator. Why would we want to avoid building the generator: surely
that is a vital part of aDSMsolution? Absolutely??”and it is also one dear to the heart of
developers, being close to the code they are used to writing. Thanks to the

overenthusiastic hyping of 1980s and 1990s CASE tools with their ?¬?xed modeling
languages and ???one size ?¬?ts all??? generators, the generator is also the area that many
developers are most skeptical about.
These two factors lead many to want to jump in and build a generator right near the
start, often hand in hand with developing the modeling language.
