Eli 4.8.0 released

Eli 4.8.0 is now available at http://eli-project.sourceforge.net/.
This release allows a user to combine Eli-generated tree computations
with scanner/parser modules created by other tools such as ANTLR, Flex,
or Bison. See http://eli-project.sourceforge.net/elionline/news4.8_toc.html
for details.


Many tools are available for creating processors that scan and parse
text. These tools differ among themselves in strategy and power. All
support mechanisms to build trees on the basis of the relationships
implicit in the input text. Once the tree is built, however, most
systems provide no further aid. The user is responsible for writing
code in C or Java to process and transform the tree.


Eli 4.8.0 has the ability to combine the scanner/parser resulting from
almost any one of these tools with tree computations generated from a
declarative specification. The user can describe the intent of the
tree computations without the need to develop the necessary Visitor
algorithm or data management. Computations can be added to or deleted
from the specification and the code re-generated, simplifying
maintenance. Standard libraries can be used for common tasks such as
name analysis, type analysis, and tree transformation.
