|Session Title|| Template Specialization
When programmers elect to use your templates, they are generally buying into the big picture of the architecture, or they’d use someone else’s template. However, it is unnecessary and counterproductive for them to be locked into every small decision driving that architecture.
Modelling tools and template designers have the option of disallowing customization, allowing full template replacement or allowing template specialization. Template replacement is an expensive option for changes that could be as small as changing scope in a single scope declaration. The real cost is in that it blocks incorporation of future template improvements.
Monolithic templates also hinder architectural evolution and require branching template sets into independent groups. This may be a significant factor in the slow adoption of the architecture provider/template user process model.
This talk focuses on understanding options to monolithic templates. For the template user, you’ll understand what hooks and other techniques to look for and demand. For the template designer, you’ll learn how to minimize the pain of customization. The techniques presented will include:
This talk presents the speaker’s recent work and research. If you’re working on modellers or generation systems, you’ll leave this talk understanding how to provide more downstream flexibility. If you’re a template developer, you’ll leave knowing which of these strategies might already by supported by your template language. If you’re a template user, you’ll leave understanding how to take advantage of the hooks available to you.
