d2pricecheck

A utility to analyze posted prices for items in Diablo 2.

Prerequisites

1. Install Go.
2. Install git (optional if you want to use git clone to get the repo).

How to Use

1. Download / clone the repo. If using git:

$ git clone git@github.com:MahlerFive/d2pricecheck.git

2. Prepare an input file.

Copy a bunch of text from a channel where people are posting items for trade. For example, in the Project Diablo 2 discord channel #sc-trade-💰.

Now, paste the text into input.txt in the d2pricecheck folder.

3. Run the price analyzer.

$ cd [path to d2pricecheck folder]
$ go run cmd/priceanalyzer/main.go --in input.txt --out output.txt

If you don't provide the --in or --out flags, it will use input.txt and output.txt by default. Make sure the path to the files is relative to the d2pricecheck folder.

4. Search the output file.

Open output.txt or whatever file you specified as the --out parameter. Search the file for the item you want to price check.

For example, if you search for Guardian Angel you might see something like:

Guardian Angel  um:1    mal:2

This means there was one person pricing Guardian Angel at um rune, and two people pricing it as a mal rune.

Limitations

There are a lot of limitations on the text parsing right now.

• Only works for unique and set items
• Item name and price must be on the same line
• Name must exactly match the full name
• Item must be first, and the price must be at the end
• Only rune prices considered
• Will not work in some cases when there are other letters other than the item name and the rune name. Letters between the item name and rune are ignored, and some common words/phrases are ignored like [O], [N], rune, and obo.

Examples that work

Tal Rasha's Lidless Eye, IST

Tal Rasha's Lidless Eye=IST

Lidless Wall [+1] =pul

[O] Lidless Wall [+1] =pul

Lidless Wall +2 Skills, IST

Examples that won't work

Tal weapon, IST

Tal Rasha's Lidless Eye, IST/GUL (this will actually parse, but it will price it at GUL and ignore IST)

Eth Lidless Wall [+1] =pul ("Eth" isn't handle when it's before the item name)

Future

This is just a hobby project so I may or may not get to these.

• Improve text parsing to remove most of the existing limitations
• Sorted rune price output
• Output examples of each price (this should help you see how different modifiers affect the price)
• Support more item types (eg. Socket item bases, common magic items like 15/40 jewels or 3/20 javs)
• Automate input by scraping Discord with a bot
• Provide a web interface and/or Discord bot for searching

Note that the intention of this project is just to help with easily checking prices so you know what to prices to post trades for, what to offer for trades, and have an idea of what items are worth keeping/muling. Even if a site is built, it's not intended to be a trading platform. This is both to limit scope and because I'm building this with the intention of supporting the Project Diablo 2 community, where external trading sites are prohibited.

Code Contributions

At the moment, I'm not accepting code contributions since this is a very early version and the code is in major flux. As things settle I will open it up.
