The program representation contained in Slim Binary files consists of a compact description of the symbol table and a syntax-oriented encoding of the abstract syntax tree that is based on a technique called Semantic Dictionary Encoding (SDE).
Instead, the dictionary table of a program is rebuild automatically during decoding of the abstract syntax tree on the consumer-side.
Figure 8 (a) contains the abstract syntax tree and the corresponding symbol table for the same sample source program that was shown in Figure 6 (a), and Figure 8 (b) shows the sequence of indices resulting from applying the SDE.
The dictionary table generated for our sample program can then be used for encoding the abstract syntax tree. For that purpose, the nodes of the abstract syntax tree are traversed in pre-order, and as each node is processed, the index of its corresponding node class is written out.
During decoding of an abstract syntax tree that has been encoded by a dynamic SDE, the same adaptive construction of the dictionary table must be performed.
Basically, such an extension might be based on the construction of an unified abstract syntax tree and a more general type system.
The Slim Binaries format, as well as SafeTSA, implements a program encoding which is based on the abstract syntax tree and hence close to the high-level source language.
Our compression scheme is based on adaptive methods such as LZW[10], but has been tailored towards encoding abstract syntax trees rather than character streams.
Finally, our prototype recognizer and plan library simplify many of our constraint checking predicates by assuming the abstract syntax tree is in a canonical form, with for and while loops replaced with a generic LOOP construct, all decisions replaced with ifs, variables moved to the right side of communicative operations and constants to the left, and so on.
The particular representations of the program source range from closely coupled to the source code (such as abstract syntax trees annotated with data and control flow information [6] to abstractions of the source code (such as flow graphs that combine data and control flow information [15, 16]).
We introduce a data structure, production trees, that are more compact than either abstract syntax trees or parse trees.
