Programming Distributed Systems with YAMI4
10.2.1 General Conventions
The YAMI4 Definition Language contains the following syntax elements:
- Keywords, which by convention are typed in
lowercase.
- Identifiers, which by convention are typed in
Camel_Case with underscores separating individual words. The reason for this convention is to facilitate later mappings to particular programming languages, which have different conventions. Some identifiers, like String, refer to standard YAMI4 types, while others, like Say_Hello are provided by user.
- Special characters.
- Comments, which start from double minus
-- and continue till the end of line.
An important constraint is that user-provided identifiers should not conflict with keywords or reserved identifiers in the target programming language. For example, Friend might look like a perfectly valid identifier for a record or field, but in C++ it will conflict with the keyword friend if the selected conversion is to lowercase. The same identifier might be valid in Ada or Java. The user should take such issues into account when choosing names for his program entities.
