Pylon is a compact foundation library for writing portable Eiffel software. It provides the classic data structures (lists, stacks, queue, sets and various tables) with associated access objects like iterators. Other useful clusters provided include: date and time, a simple portable serialisation facility, along with a few other utilities for number formatting and string parsing.
SNiFF+ for Eiffel is a 'fuzzy parser' which extends the SNiFF+ development environment for use with the object-oriented language Eiffel. You get syntax highlight in the editor, a class browser, cross reference browsing, and much more. It works independent of your Eiffel compiler and can even cope with source files with syntax errors.
xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
