Hi guys
we have a position for a PhD. If you are interested we can talk at ESUG 2012 or
by Skype.

Context: Dynamically-typed languages cannot take advantage of static type
information. In this context we would like to study
the benefit of the introduction of static types *annotations* on library design
and general robustness.
The benefits can be at the level of the robustness (bug identification), but
also tools (IDE) and support for assembly generation/c
in case of JIT.
The PhD grant is financed in the context of the Safe Python project therefore
the Ph.D. will have to work in contact
do we with the project partners and help in the context of some deliverables.
The following tasks have to be done:
- RPython is not formally defined. One of the first task will be to
define the formal semantic of RPython.
One approach is to write a RPython interpreter based on an operational
semantics and to compare the output
with the RPython interpreter. We will certainly use PLT redex which is
a domain-specific language to specify
and debug operational semantics.
- We may use the abstract syntax tree of PyLint and use the Frama-C
infrastructure. We will also consider to
build a Python parser based on petitParser.
- Define of some default metrics may also be necessary for the
SafePython project. Their definition should
be trivial on ASTs.
- Analysis of the benefits of static typing for RPython. One idea is to
study the existing python libraries
and analyze the "distance" to the RPython subset.
- Exploring type checking in presence of inconsistent type annotations.
- Since we are developing Pharo and that static type annotation are
important to
support C or assembly generation, we would like to apply the same
technique to Pharo:
- define a syntax to support type annotation (reuse the one
developed by Pleaid team member)
- perform some analysis of existing library.
