Clientside Rule Processing

Clientside application used for event processing.

Features

• rock solid and fast (thanks to Rust)
• compiled to WASM, efficient and portable format
• flexible parsing with pest parser

Installation & usage

Prerequisites:

• Rust
• wasm-pack (or just cargo install wasm-pack)

Building:

1. Open project directory in terminal
2. Navigate to /browser module
3. Execute build command `wasm-pack build --target web`
4. Enjoy results from `/pkg` directory

Testing:

1. Open project directory in terminal
2. Execute command `cargo test`

Usage:

The main file you will interact with is located in /pkg directory and is named browser.js. It exports one function process_event as documented in the API section. It processes an event created by user, updates and returns their context (game state) along with a result (reward). The function is asynchronous, so expect a Promise.

Sample usage from HTML file can be seen in /browser/index.html

API

Origin:

browser.js

Function:

name: process_event

type: async (Promise)

argument: dictionary

sample argument format:

{
   "event":{
      "parts":{
         "player":{
            "NumberBased":1
         },
         "on":{
            "DateBased":"2024-10-27"
         },
         "at":{
            "TimeBased":"10:30:00"
         },
         "result":{
            "NumberBased":100
         }
         // other fields
      }
   },
   "game_state":"",
   "simple_rules_str":"simple_rule: player 1 on 2020.01.01..2026.01.01 at 8:30..23:30 achieving 100 repeat +",
   "compound_rules_str":"",
   "rule_results_str":"simple_rule -> msg nicely_done_simple_rule"
}

returns:

dictionary if succeeded, undefined otherwise

sample success:

{
   "game_state":"...",
   "results":[
      [
         "Message",
         [
            "nicely_done_simple_rule"
         ]
      ]
   ]
}
