Dear all,

At tomorrow's SEN1 meeting, Tijs will talk about his latest research
project:

On the Origins of Strings
(joint work with Paul Klint)

Rascal is a programming language suitable for writing meta-programs
that transform source code to other/new/modified/more source code. In
many use cases the input is a string and the output is a string. We
present initial musings about how to relate fragments of the output
string to either the input string(s), or the meta-program itself. One
envisioned application is relating compiler errors in generated code
to the string templates that were used in a code generator. Although
the (general) origin-tracking problem has been amply studied (also at
CWI), we conjecture that restricting our domain to strings will allow
us to achieve better results. Open questions include: how to preserve
origins across string operations and how to implement string origins
efficiently.


We start at 10am in room L016. See you there!

Cheers,
Bas
