This update will dust some cobwebs off of rivescript-go and bring some nice modernized features that the JavaScript version (especially) had going for it already.
This will provide version 0.4.0 for rivescript-go.

v0.4.0 - Aug 15, 2023
This update will modernize the Go port of RiveScript bringing some of the
newer features that were available on the JavaScript or Python ports.
The ?Keyword Command
This update adds support for the newer ?Keyword command in RiveScript.
This command works around a Unicode matching bug that affected the
Go, JavaScript and Python ports of RiveScript. For example:
// You wanted this trigger to match if "你好" appears anywhere
// in a user's message, but it wasn't working before.
+ [*] 你好 [*]
- 你好!
// Now: use the ?Keyword command in place of +Trigger
? 你好
- 你好!
The optional wildcard [*] syntax didn't work when paired with Unicode
symbols because the regular expression that [*] is turned into (which
involves "word boundary" or \b characters) only worked with ASCII latin
characters. The ?Keyword command works around this by translating into a
+Trigger that tries every combination of literal word, wildcard on either
or both sides, and optional wildcard, to ensure that your keyword trigger
will indeed match your keyword anywhere in the user's message.
CaseSensitive User Message Support
By default RiveScript would always lowercase the user's message as it
comes in. If this is undesirable and you'd like to preserve their actual
capitalization (when it gets captured by wildcards and comes out in their
<star> tags), provide the new CaseSensitive boolean to your RiveScript
constructor:
The built-in rivescript command line program adds a -case parameter
to enable this option for testing:
rivescript -case /path/to/brain
JavaScript Object Macros
The official JavaScript object macro support library has a couple of
exciting new updates.
Firstly, the JavaScript engine has been replaced from
github.com/robertkrimen/otto with
github.com/dop251/goja which should
provide a better quality of life for writing JavaScript functions for
your bot. Goja supports many of the modern ES6+ features including the
let and const keyword and arrow functions.
Additionally, the Goja runtime will be exposed at the .VM accessor
for the JavaScriptHandler class, so you can directly play with it and
set global variables or Go functions that can be called from your
JavaScript macros in your bot, allowing for much greater extensibility.
Other Changes
Add shellword parsing for <call> tags: you can pass "quoted strings"
in which will go in as one 'word' in the args array, instead of the
arguments being literally split by space characters. This brings the
Go port of RiveScript in line with the JavaScript port which has been
doing this for a while.
Fix the rsts_test.go to properly load from the RSTS (RiveScript Test
Suite) git submodule.
