Agena

Agena is an easy-to-learn procedural programming language suited to be used in scientific, educational, linguistic, and many other applications, including scripting.

• The new function `tables.include` inserts values into a table of (sub)tables. If necessary, it creates a subtable before insertion.
• The new function `hashes.lua` returns the hash of a string internally used by Agena.
• The following `hashes` functions no longer need a second argument, i.e. the number of slots, to make them comparable: Instead when given only a string or number, they return its actual hash: `djb`, `djb2`, `fnv`, `jen`, `oaat`, `pl`, `raw`, `sax`, `sdbm`, `sth`, `mix64`, `mix64to32`.
• Improved general error messages. The new `environ.kernel/errmlinebreak` setting allows to change the maximum number of characters to be displayed per line in syntax error messages.
• The new function `debug.funcname` returns the name of the function from which it has been called. It is a wrapper for "debug.getinfo(n, "n").name". The function may be useful to create more flexible error messages.
• `tables.dimension` did not work correctly if given a structure as the initialisor. This has been fixed.
• In `strings.ljustify` and `strings.rjustify`, the filler can now also be a number.
• `mprint`, `checkoptions` now detect whether they have been passed too many arguments.
• Added new API functions agn_rawgetfield, agn_rawinsert, agn_rawinsertfrom. See manual for their features.
• This release has been Valgrind-checked on x86 Linux and Mac OS X to ensure there are no memory leaks.
