JSON_DIRECT_OOB tokencontrol for json that is too large for being a token
optional 5th param to jsonopen, timeout in seconds for this call (applied 1st to connection, then to transfer) so total max is double

^jsoncopy no longers fails if what you pass is not a json structure, it merely returns what you passed

version 6.85 10-8-2016

If (^function()) fails if function returns false (as well as previously returning 0 or failing
@4 = ^jsongather(jsonstructure) - now allowed in addition to ^jsongather(@4 jsonstructure)
source= command line parameter will start up using that file as input

version 6.62 7-24-2016

WARNING- USER TOPIC FILE FORMAT CHANGED, old ones will self destruct and clear to empty 1 :restart can take a 1st argument of "erase" which means system should erase topic file of current user (changing systems) and it can take up to 4 replacement command line parameters 2. ^jsonlabel(label) 3. ^jsonundecodeString(field) 4. $cs_externaltag ^setoriginal, ^setcanon, ^settag, ^setrole

version 6.61 7-17-2016

^savesentence(label) and ^restoresentence(label) will save and restore an entire sentence preparation, so you can jump back and forth between sentences in pattern matching w/o real cost.

version 6.5a 5-18-2016

ChatScript now enforces a rule that a function variable name should not be the name of an existing function (hides the function). This may cause your builds to break until you rename your variables in question.
:trace full -- when set, disables NOTRACE() so everything is traced using all flags :trace ignorenotrace just turns on the flag, leaving your other bits intact :trace none turns off all bits and any ignorenotrace flag
PRIVATE_CODE now requires PrivateInit() and PrivateRestart() and PrivateShutdown() functions and file privatetestingtable.cpp for any :test overrides, a command line paramemter private= passes its value thru to PrivateInit
ResponseRuleID(-1) does all to date

version 6.5 -- 5-7-2016 WARNING- change of directory structure in TOPIC

TOPIC now gets subdirectories for each of the build layers. While it will work with content in the old format (all at top level) or the new format (subdivided into BUILD0 and BUILD1 subdirectories, it will only :build into the new format. If you have deployment scripts, make sure when they perform builds that CS can create these subdirectories.
when using pattern- u: ($$test?) which would see if word was found in sentence, if it is a quoted string "buy me" it will be able to find that sequence as matching.
^jsonarraydelete([INDEX,VALUE] array index) to remove element and renumber later ones down
while !not in pattern checks that not doesnt appear later in the sentence, !!not checks that it is not the next word
:trace RULEFLOW will just show the rules as it does their outputs. It is a terse flow of control view.

version 6.4 4/30/2016

^importfacts may have null as its set value. It wont store the facts created in a factset.
^conceptlist takes optional 3rd arg, prefix to filter by

^CSSHUTDOWN added for system going down behaviors

version 6.3a 4/16/2016

jsonarrayinsert allows a leading flag UNIQUE, in which case it does not add to array if already there.
^notrace(... ) turns off regular tracing for the given stream. Explicit function and topic traces are not blocked, just normal :trace xxdx
$cs_jsontimeout sets json wait delay (300 second default)
save/restore local variables allow you to avoid naming collisions -- see advanced manual outputmacros: e.g. outputmacro: ^myfunc(^arg1) ($$tmp $$tmp1) code the values of $$tmp and $$tmp1 are saved and restored across the call, so the macro may safely write on them.
^return(...) see advanced manual outputmacros:

version 6.3 4/10/2016

~twitter_name detected as concept for @xxx names and ~hashtag_label detected as concept
$cs_beforereset and $cs_afterreset if, assigned to functions, will execute them before and after a :reset. This is your chance to pass some information across to the newly reinited user. I store data in _match variables before and retrieve them after.
Outputmacros can be declared as executable javascript code. New manual in Esoterica for that.

version 6.2g 3/27/2016

fixed slowdown introduced into the engine a few versions ago.

version 6.2f 3/25/2016

^jsonparse now accepts a flag argument of SAFE, which means you can use it against data the extends beyond the minimal, meaning if you memorize OOB data after [, you dont have to care to find the closing ], which will be hard since JSON itself has ] in it. Eg u: ( [ _* ) $$jsonfacts ^jsonparse(safe _0)
support for spanish spellchecking

version 6.2e 3/20/2016

version 6.2d 3/14/2016

^substitute 1st arg can now be "insensitive", meaning character search and case insensivive. Or you can provide a string like "word insensitive" to pass 2 arguments.
%originalSentence will give you the raw user input for the current sentence (after tokenization)
^original(_0) will give you the original text of the user that this match derives from (see docs for more details)

version 6.2c 3/5/2016

You no longer have to backslash [ in an active string. You can do ^"[$count]" with impunity. That means that using [] [] notation to designate a choice of text is no longer effective inside an active string"
^Next(loop) will skip the rest of code in a loop and begin the next interation (NO MATTER how far up the call chain the loop actually is)
CS can now be run old-style (all executables at top level) or within BINARIES
%host gives you the name of the currently running host.
^pos(verb be present/past XXX) optional 4th arg to verb form, names pronoun or noun used, so better handles irregular verbs
$cs_language, if set to spanish, alters spellchecking for spanish

version 6.2b 2/24/2016

Moved executables and DLLS to folder BINARIES. You must now run CS from there rather than top level. CS changes current working directory up 1 level after starting. Revise Cron jobs and shortcuts to the exe appropriately.

version 6.2a 2/20/2016

^norejoinder() makes this rule unable to set its rejoinder.
CS now allows multiple forms of uppercase words, e.g., ID and Id
Recently a major security hole in glibc, open source c library was announced and patched. CS uses glibc. This build uses the new version. If you are running older versions of CS, there is some security risk and you are advised to upgrade to this executable linux version, or apply sudo yum update to glibc (or equivalent commands) and then rebuild your existing sources.
optional 3rd argument to ^jsonpath(xx yy safe) tells it to return ugly data with doublequotes around it. Things with embedded json data or whitespace need to be passed into jsonformat using safe data.

version 6.2 2/14/2016

documented existing assignment abilities: @3 = @2 @3 -= @2 @3 += @2 @3 = $$factid @3 += $$factid @3 -= $$factid
new command line parameter timer=15000x10 to control how long a volley can last before being abandoned by time. 1st number is millisecond limit, 2nd is a checking frequency (reducing load of getting the time frequently)
%maxmatchvariables and %maxfactsets given the highest legal number for those respective things
UNLIKELY INCOMPATIBLE CHANGE: previously if you used match variables inside a nested pattern component, e.g., u: ( _this ( my _*1 ) ) it would be discarded on return to the top level. THEREFORE except in unusual cases, you would not have nested match requests. NOW... they are not discarded. If the above matches, _0 and _1 are both defined. Same for u: (this _(my _{often} dog)) which sets 3 match variables

version 6.1d 2/7/2016

new command line parameter debug= allows you to execute a :debug command on bootup and then exit. eg. "debug=:trim USERS 4"
IF tests can now be made of a std rule pattern (including memorization etc) using form if (pattern ....) {} which means you can match input and even memorize during the if test

version 6.1c 2/2/2016

^sequence added, similar to refine, except instead of only executing one rule, executes all matching rules.
Added :common word1 word2 to tell you the concepts they both particpate in, closest first.
$bot has been renamed $cs_bot and $login has been renamed $cs_login with script errors if you use the older names.
added internal ~timewords as an enumerated concept as well.

version 6.1b 1/25/2016

variables owned by the bot can be defined (always resident unchanged accessable to all users) - see Advanced Variables in advanced manual
$cs_trace enables and tracks traces by user
right hand side of a comparison in a pattern may now be a double-quoted string, looks at the inside of the quotes

version 6.1a 1/21/2016

version 6.1 1/17/2016

concept from ontology concepts: ~daynumber renamed to ~dayindex so as not to collide with engine concept.
~common7 redacted
^load(name) to dynamically load a layer of topics (analogous to layers 0 and 1 that load on startup)

version 6.01a 1-9-2016

DICT/BASIC has a small dictionary of words thru grade 6, suitable for use on mobile devices seeking to minimize CS memory use. See end of Finalizing a bot: Mobile size issues

version 6.01 1-7-2016

easier to follow output tracing
jsonopen now supports PUT as a type (with arguments just like POST)
^length now accepts the name of a json object or array, and returns the number of elements it has
^match can take a rule tag instead of a pattern, using the pattern of that rule.

version 6.0 1-02-2016

easier to understand pattern tracing
^print accepts more flags (RESPONSE_ ) controlling output
%timenumbers for a complete second minute hour dayinweek dateinmonth month year data

version 5.93 12-31-2015

New manual "ChatScript Common Beginner Mistakes"
time.tbl file removed from worlddata, its 2 concepts merged into ontology concepts, whose order of data has changed concept: ~month_names (Apr April Aug August Dec December Feb February Jan January Jul July Jun June Mar March May may Nov November Oct October Sep Sept September ) concept: ~month_names_index DUPLICATE (3 3 7 7 11 11 1 1 0 0 6 6 5 5 2 2 4 4 10 10 9 9 8 8 8 ) concept: ~daysinmonth DUPLICATE (30 30 31 31 31 31 28 28 31 31 31 31 30 30 31 31 30 30 30 30 31 31 30 30 30) # 0-based concept: ~month_proper_names DUPLICATE (April April August August Decemeber December February February January January July July June June March March May May November November October October September September September )
:trace none now also turns off all topic and macro tracing
$cs_utcoffset now accepts time notation as well, like -02:30 to adjust 2.5 hours before utc.

the json argument "unique" has been deprecated. it is no longer needed.
PRIVATE_CODE define supports you appending code to functionexecute.cpp w/o changing engine source. See new manual INSTALLING AND UPDATING CHATSCRIPT

version 5.9 12-14-2015

renamed ~verbs to ~verblist, ~prepositions to ~prepositionlist, ~adverbs to ~adverblist and ~adjectives to ~adjectivelist - these lists are not from the pos-tagger and should not be used in scripts. They are aggregation data about what is in the corresponding files in ONTOLOGY.
:show newline forces newlines to remain in the log file for respond: and start: lines.
renamed ^jsonprint to ^jsontree so you can remember it vs ^jsonwrite 4 ^jsonformat( textstring) takes a json string and writes it so that all keys have double quotes around them. So you can build a json string from a CS format string w/o having to have (and escape) quotes around the field names
new system variable %http_response returns most recent response code from libcurl (for ^jsonopen)
optional 1st argument to ^jsonopen, ^jsonparse, ^jsoncreate, ^jsonobjectinsert, ^jsonarrayinsert is word "permanent" to tell the facts to not be transient and "unique" to make the facts unique across volleys.

^jsonparse and ^jsonopen take optional 1st argument "UNIQUE" allowing array and object naming to be unique based on volleyCount
$cs_looplimit, if defined, will replace the default 1000 value limit on how many iterations of a loop the system will stop at to protect against runaway loops
Findtext will now substitute _ to space in source and target before matching, to provide matching either notation.
^canon(word canonical) is analogous to :canon word canonical, and only works during :build. Used for table control over setting canonicals.
^jsondelete(factset jsonfact) will delete the fact and all facts referred to by it and if the fact is an array fact, will renumber all later array value facts down 1.

OUTPUT_NOSTORE renamed OUTPUT_RETURNVALUE_ONLY

version 5.72 10/11/2015

new ^print flags: OUTPUT_RAW - does not try to interpret " or [ or { or ( OUTPUT_NOSTORE - does NOT save the answer, but instead just returns it.
^JSONWRITE(id) given json facts referred to by the root "id", creates the corresponding JSON string sans any line feeds
new manual ChatScript Engine Manual (in esoterica)
Harry (in topic keywordless) now can illustrate Json calls by calling wikipedia for an extract if you say: "what is a root"
documented that \ can escape an entire token in patterns, not just a character. hence ( \test=5 ) means the entire token test=5 and not a comparison of test with 5
No longer providing 32bit LINUX # version executables. You need to build them yourself. Or tell me you want it. if there is enough demand, I will continue them.

version 5.7 9/27/2015

^define takes a second argument of "all" or a third argument of "all" to display all meanings or of a particular sort.
user flags on facts extended to 8 from 4 and JSON_xxx fact flags named as well. FACTS manual advanced section now documents a bunch of fact flags.
:trace JSON added
JSONOPEN & JSONPRINT & JSONPARSE & JSONPATH provide support for internet JSON access

version 5.61B 9/16/2015

^cs_topic_enter(^topic ^mode) and ^cs_topic_exit(^topic ^result) allow you to intercept calls to do a topic.

version 5.6 8/28/2015

changed LIVEDATA path to be the unchanged path for initsystem embedded CS users.

version 5.54 8/24/2015

new tokencontrol value UNTOUCHED_INPUT. if set to exactly that, the system will tokenize based on spaces only. 2 :tracedfunctions List all user defined macros currently being traced
:tracedtopics List all topics currently being traced

version 5.53a 8/6/2015

^respond now takes multiple arguments to try in order (similar to the new ^gambit)

version 5.53

in debugging manual documented all the individual :trace options

version 5.52

filesxxx.txt files hunt order now includes RAWDATA folder.
Gambit now takes a series of things to try in order (up to 15) with FAIL as a final legal choice. WARNING: Back at the beginning of CS 5.xxx ^gambit(PENDING) changed meaning to no longer include the current topic. But this can be "recreated" by doing ^GAMBIT(~ PENDING) ^gambit(~ PENDING ~mygeneral) will do current topic, if no gambit then PENDING topics, if no gambit then ~mygeneral topic.
new command line parameter authorize=" ... " to supplement authorizations system for debug commands 4 new command line parameter nodebug disables user issued debug commands
documented existing command line parameters build0= and build1= which do command line builds

version 5.51

speech input/ouput in WEBINTERFACE (for chrome/safari)
GetRule(x y) takes 0 as y, meaning the top level rule above us. 3: :verify takes optional 1st param a variable indicating what tokencontrol value to use.

version 5.5

new script marker - describe: $myvar "used to store data" _10 "tracks pos tag" takes a $var or an _var or an @set or a ^macro or ~topic and a text string and saves that as documentation. See :list
:list {$ ^ ~ _ @} will list documented items (and undocumented variables). See Finalizing a bot 3: ^sort now takes optional first argument alpha or alphabetic meaning sort by name instead of value. Also takes instead "age" meaning put oldest facts first.
loop (@2) now uses count of set as loop control. Previously you could also use @2 to represent a count in patterns and IF tests.
:prepare now takes optional first argument, a user variable to set the tokencontrol to.
You can now control what tracing is done within a topic. :trace ~topicname takes the current trace flags, uses them for that topic, and sets trace to 0. Therefore: :trace basic match ~topicname all will set ~topicname to do those 2 kinds of traces and turn off regular trace, then turn on regular trace for everything else
:trace input adds current input to the trace 7: removed the comment in a concept definition (use describe: instead).
concept definitions can now be annotated with ONLY_NOUNS or ONLY_VERBS or ONLY_ADJECTIVES or ONLY_ADVERBS. This requires that only the corresponding interpretation of words can match, both in this set and in ALL concepts recursively referred to by this set. It is similar to marking a concept with NOUN but doesn't actually change any existing property bits, merely requires them if the pos tagger can determine. ONLY_NONE added to a concept blocks any propogate thru it

version 5.4 (extra stable)

serious bugs with << and %tense fixed
optional first flag to createfacts STRIP_QUOTES to remove quotes from arguments
userbugs table in postgres user client to record CS detected bugs

^DELETE can now kill an individual fact
^conceptlist now requires a first argument of TOPIC CONCEPT or BOTH
^incontext(label or topic.label) fails if the given label has not generated output within the 4 previous volleys. Succeeds if label has.

prefixing username on startup with * in client or stand-alone mode, allows user to speak first.

version 4.6

the stand alone system recognizes 3 oob messages: alarm=xxx callback=xxx loopback=xxx If alarm is set, an incoming [alarm] will be sent to CS after the xxx milliseconds have been completed after completion of any current volley.

If a callback is set, an incoming [callback] will be sent to CS after xxx milliseconds, unless the user starts typing first, in which case the callback is cancelled

If a loopback is set, an incoming [loopback] will be sent to CS xxx milliseconds after the most recent output, unless the user starts typing first, in which case it resets and tries again after the next volley

version 4.5

if the filesxxx file is not found at the top level of CS, it will also look at the containing folder. THerefore you can put your own rawdata and filesxxx build files in there, put the CS folder in there, and update CS by merely replacing the CS folder entirely. If you have your own livedata, it can be in that outer folder and a command line parameter tells CS to use it instead of the default folder.
system= and english= can be used to redirect accessing those folders within LIVEDATA. This means you can make your own copy of livedata (eg above cs) and then redirect CS to that to have your substitutions, but redirect these 2 folders to stay within chatscript for updating.
