Enso Compiler and Interpreter
Truffle Nodes creation convention
All Truffle nodes that are expected to be created as part of ASTs
should implement a public, static build
method for creating an instance.
If the node is DSL generated, the build
method should delegate to the
autogenerated create
method, so that nodes are always created with build
.
Such a convention allows us to easily switch node back and forth between
manual and DSL generated implementations, without the need to change its
clients.
The only exception are nodes that are never expected to be a part of an AST
– e.g. root nodes of builtin functions, for which an asFunction
method
should be implemented instead.
This convention should be implemented for every node throughout this codebase – if you see one not obeying it – please fix it.
