lazarus-bazmon-server

A Bazaar search tool for the Lazarus EQ Emulator server.

Motivation

The EQ Bazaar interface does not work on Lazarus, so people use the excellent hosted Magelo web site (https://www.lazaruseq.com/Magelo/index.php?page=bazaar) for the Lazarus server.

We are now able to query the Bazaar in game.

How it works

This is achieved by running two scripts:

Front end: A normal Lua script (found here) that is run by MQ's /lua run <script> functionality. It presents the UI and writes its data to a standard .ini file just like any other plugin. It reads query result data from a separate CSV file populated by the backend server.
Back end: A standard Go program (this repo) that watches for changes in the Lua .ini file and uses that to essentially proxy queries to the Lazarus Magelo Bazaar search page. It writes query results to a CSV file that can be in turn read by the Lua script to show those search results in game.

Usage

Set up the front end

Setting up and using the the front end Lua script can be found in its repository.

Set up the backend (this)

Download the prebuilt binary from Github (here) or clone the repo and run it via the command line:
```
cd C:\YourReposPath\
git clone [email protected]:ZehenForever/lazarus-bazmon-server.git
```
Run the main program with a CLI flag that tells it where the MQ/E3 conf directory is located. This must match how you installed your Lua script. The defaults should work out of the box.
```
go run main.go -config '/c/E3NextAndMQNext/config'
```
And optionally with more verbose output, if desired:
```
go run main.go -config '/c/E3NextAndMQNext/config' -logLevel debug
```

When it first starts up, it should provide some output depending on your log level:

2024-03-18T12:44:13-06:00 INF Starting Bazaar Query Server
2024-03-18T12:44:13-06:00 DBG Using log level: debug

2024-03-18T12:44:13-06:00 INF Using results file: C:/E3NextAndMQNext/config/BazResults.csv

And then when the Lua script is run on the client and you click the "Search" button in the UI, that will write to the BazMonitor.ini file, and this script will see that change on the file system, read that search request, and query the Lazarus Magelo Bazaar web app, and then write its results to the BazResults.csv file.
