Basically, whitespace will be stripped + down to readable levels, unless the xml:space attribute is used to + indicate otherwise. + - Fixed bug in PatternMgr where the character '1' was mistaken identified + as punctuation to be stripped, instead of the intended '!'. + +version 0.8.4: + - Fixed bug in AimlParser creation, if the aiml module was not in the same + directory as the script that imported it. + - Improved Unicode support (again) (thanks to Daniel Kottow for his help). + - 2nd pass at documentation. All functions now have useful, properly-formatted + docstrings. + +version 0.8.3: + - Reworked the way AimlParser objects are created, to allow support for + XML namespaces in a future version. + - First pass at Unicode-proofing the whole system, so that multi-lingual + AIML files can be processed. + - Added support for "index" attribute in "star", "thatstar" and "topicstar" + elements (thanks to Robert D. Cotey for the patch!). Also added type-check + to ensure that the value of the "index" attribute is an integer. + +version 0.8.2: + - Added protection against infinite AIML recursion. + - Removed the deprecated Kernel.getBotName and Kernel.setBotName functions. + - Added workaround for Unicode input crash. Feeding the Kernel Unicode + input no longer crashes the interpreter, but some internal input-formatting + operations must be skipped, which could cause some nonsensical replies + (like you're not already used to nonsensical replies, though...) + +version 0.8.1: + - "system" elements now attempt to intelligently convert between UNIX-style + and Windows-style pathnames as appropriate. For cross-platform compatibility, + all AIML files should use UNIX-style paths inside their "system" elements. + - Fixed crashes under Windows9X when a "system" element is executed when + w9xpopen.exe is unavailable. + - Re-piped most errors and warnings to go to stderr instead of stdout. + - Fixed bug that would cause the the bot to stop responding to any input in a session + if the "that" or "topic" strings were 100% whitespace (but still not empty). + - Fixed bug that would cause multi-line "that" strings to become corrupted. For + example, "Hello there.\nNice to meet you" would become "HELLO THERENICE TO MEET + YOU" when queried for that-matching. + +version 0.8: + - Removed support for non-standard "mode" attribute in "system" elements. + It just wasn't worth breaking the AIML standard for. + - Reworked persistent session support (I warned you!). The old method involving + Kernel.persistentSessions() has been removed. Instead, there is a new + Kernel.getSessionData() method which gives the bot author access to the session + data. You can store this data however you wish. Session data can be restored + later by repeated calls to Kernel.setPredicate(). + - Improved AIML parser error handling; instead of aborting the entire file, a + parse error now only ignores the current category and forges ahead. To check for + parse errors, check the return value of AimlParser.getNumErrors() after parsing. + +version 0.7: + - Further improved AIML parsing; missing or invalid XML attributes are now + detected at parse-time. There's also a first stab at support for Forward + Compatibility Mode: if the "version" attribute of an AIML tag is not 1.0.1, + the parser is much more forgiving of unknown or missing XML tags and attributes. + - Added "support" for the 'gossip' tag. The specific behavior of this tag is + totally undefined; currently, the PyAIML implementation treats it as a big + no-op. Its contents are ignored, and it returns the empty string (but at least + it isn't flagged as a syntax error!) + - Oops; I've implemented 'person' as 'person2' and vice versa this whole time! + Swapped them back; they should each behave correctly now. + - A bit of code cleanup, with an emphasis on using proper XML/AIML terminology + whenever possible. + - Fixed some exception-masking in the 'condition' element processor, which could + prevent AIML parse errors from being reported. + - Added full support for the "bot" tag (previously only the 'bot name="name"' + form was supported). Bot predicates are set using the Kernel.setBotPredicate() + function. Note that Kernel.getBotName() and Kernel.setBotName() have been + deprecated, and will disappear in a future release. + +version 0.6.1: + - Fixed undefined variable exception that was thrown whenever there was no + match for the user's input. + - Fixed an infinite recursion bug caused by processing two or more nested + 'srai' or 'sr' elements. + +version 0.6 + - Completely rewrote the LearnHandler class (which handles all AIML parsing) + to be much less forgiving of incorrect AIML. Currently, any AIML errors + outside of "template" elements should be caught and reported at load-time. + AIML errors inside templates are still not detected until run-time. + - Added support for atomic 'person' and 'person2' tags (they implicitly use + 'star' as their contents if none are provided). + - Oops; Kernel.respond() was DEFINITELY not thread-safe. Now it is, provided + you're using Python's standard 'threading' module. If not, you'll have to + provide your own mutual-exclusion system to ensure that only one thread + is calling Kernel.respond() at a time. + - Recursive tags ('srai' and 'sr') no longer add their intermediate results + to the input and output history. + - EXPERIMENTAL FEATURE: persistent sessions. If enabled using + Kernel.persistentSessions(True), session data will be written to disk + after every response. This lets session data be preserved when the + Kernel is destroyed, at the expense of a small performance hit (all + that extra disk I/O). The semantics of this feature may change in future + releases! + - Added support for the "id" tag (it returns the session ID). + - Added support for the "topic", "topicstar" and "thatstar" tags. + - Commented up the test.py file. + - Added a summary to the end of the Kernel.py self-test (since there are now + too many tests to fit on screen). + - Added support for multi-sentence input. The user's input is split into + individual sentences, each of which is treated as a completely separate + piece of input. I'm *pretty* sure this is the Right Way(tm). + +version 0.5 + - The filename inside Learn tags can now contain wildcards. Besides + simplifying the loading of multiple files, this allows the possibility + of loading AIML files that may not exist without crashing the + interpreter. + - Attempting to set the value of a predicate in a nonexistent session + now automatically creates the session, instead of silently doing nothing. + - "set" tags now output the new value of the variable, as well as assigning + it. + +version 0.4.1 + - Unknown AIML tags are handled in a more forgiving fashion. If an + unknown tag is encountered, instead of ignoring its contents entirely, + the contents are processed and returned unaltered. + - Added support for "bot name='name'" tags, both in patterns and in + templates. This also fixes a nasty infinite loop crash when a user + says Hello to a bot. + +version 0.4 + - Added support for "star" and "sr" tags. + - Considered adding support for the "secure" tag, but decided against it. + see SUPPORTED_TAGS.txt for more information. + +version 0.3 + - Cleaned up AIML processing code to remove some unnecessary + special-cases in the interpretation algorithm. + - Added support for "input" and "that" tags. + +version 0.2 + - 50% speedup in Kernel.loadBrain() and Kernel.saveBrain(). + - The optional 'learnFiles' and 'commands' arguments to + Kernel.bootstrap() can now be either strings or lists. This + allows multiple files/commands to be loaded during + initialization. + - Added support for "person" and "person2" tags. + - Added general word-substitution functionality. This opens up + the potential for localizing PyAIML into non-English languages. + See DefaultSubs.py for more info. + +version 0.1: + - Initial release.
