## hiveengine
[hiveengine](https://github.com/holgern/hiveengine) is a python library for working with [hive-engine.com](https://hive-engine.com/) tokens and NFTs.
I released version 0.2.1 which can be installed by
```
pip install hiveengine
```
hiveengine is using [beem](https://github.com/holgern/beem) for broadcasting transfers and custom_json to the HIVE blockchain. hiveengine is only working when using HIVE nodes. You can check the currently set nodes with
```
beem config
```
Hive nodes can be set with
```
beem updatenodes --hive
```
## Changelog
### 0.2.1
* Fix nft_id list in nftbuy, nftcancel, nftchangeprice and nftsell
### 0.2.0
* add NFT support has been added (collection, nft, nftmarket, nfts)
* add NFT related commands to cli (collection, nftbuy, nftcancel, nftchangeprice, nftlist, nftopen, nftparams, nftsell, nftsellbook, nfttrades)
## NFT support has been added to the command line tool
NFT support has been added to hiveengine in version 0.2.0. The following NFT related commands have been added.
### collection
```
Usage: hiveengine collection [OPTIONS] ACCOUNT [SYMBOL]...
Return NFT collection for an account
```
For example:
```
hiveengine collection holger80 CITY
```
which returns
```
NFT: CITY
+-------+---------------+---------------------------------------------------------------------+
| _id | lockedTokens | properties |
+-------+---------------+---------------------------------------------------------------------+
| 12659 | {'SIM': '20'} | {'name': 'Basic Home', 'population': 4, 'income': 1, 'type': '1st'} |
+-------+---------------+---------------------------------------------------------------------+
```
### nftbuy
```
Usage: hiveengine nftbuy [OPTIONS] SYMBOL [NFT_IDS]...
Buy nfts from the market
Options:
-a, --account TEXT Buy with this account (defaults to
"default_account")
-m, --market_account TEXT Market account which will receive the fee
(defaults to "nftmarket")
-y, --yes Answer yes to all questions
```
The market account can be set to any account except the seller. The market account will receive the fees, when the token was successfully bought.
hiveengine default value for the market account is @nftmarket, which was created by me. I will decide later what to do with received token. When I figure it out to which buyer to received tokens are connected, @nftmarket would share 50% of the received fees with the buyer (the received fees are excluded from token transfer history).
Setting the market account can be used to send the fee to an alt account:
```
hiveengine nftbuy -a holger80 -m my_alt STAR 100
```
In this case, holger80 will receive the NFT 100 and my_alt will receive the fee share in tokens.
### nftcancel
```
Usage: hiveengine nftcancel [OPTIONS] SYMBOL [NFT_IDS]...
Cancel a nft sell order
Options:
-a, --account TEXT Buy with this account (defaults to "default_account")
-y, --yes Answer yes to all questions
```
This command can be used to cancel an open order:
```
hiveengine nftcancel -a holger80 STAR 7147
```
which asks me to proceed:
```
Canceling selling of following nfts:
+-------+-----------------+----------------------------------------------------------------+
| nftId | previousAccount | properties |
+-------+-----------------+----------------------------------------------------------------+
| 7147 | holger80 | {'type': 'FanBoost1', 'class': 'fanboost', 'stats': '1,0,0,0'} |
+-------+-----------------+----------------------------------------------------------------+
continue [y/n]?
```
### nftchangeprice
```
Usage: hiveengine nftchangeprice [OPTIONS] SYMBOL [NFT_IDS]... NEWPRICE
Changes a price of an open sell order
Options:
-a, --account TEXT Buy with this account (defaults to "default_account")
-y, --yes Answer yes to all questions
```
The following command changes the price of my order to 1160 STARBITS:
```
hiveengine nftchangeprice -a holger80 STAR 7147 1160
```
### nftlist
```
hiveengine nftlist
```
returns all existing NFTs:
```

```
This command returns the currently open orders for each NFT type.
```
hiveengine nftopen -g name -v "Basic Home" CITY
```
would return the open orders for one specific NFT type:
```

+-------------+---------------------------------------+-------+
| SIM | {'name': 'Basic Home', 'type': ''} | 0 |

when not set)
-f, --fee INTEGER Market fee 500 -> 5% (defaults is 500)
-y, --yes Answer yes to all questions
```
This command creates a new sell order:
```
hiveengine nftsell -a holger80 STAR 7147 1150 STARBITS
```
and I can then check if it has worked by:
```
hiveengine nftsellbook -g type -v FanBoost1 -l 5 STAR
```
### nftsellbook

It is possible to limit the returned open sell orders by a specific property:
```
hiveengine nftsellbook -g name -v "Basic Home" -s SIM -l 10 CITY
```
will return the 10 cheapest offers for Basic Home NFTs which are sold by SIM tokens:
```
+--------+------------+------------+---------+-------------+--------+-----------+
| nftId | account | name | price | priceSymbol | fee | est. HIVE |
+--------+------------+------------+---------+-------------+--------+-----------+
| 191946 | lestrange | Basic Home | 329.000 | SIM | 2.50 % | 1.704 |
| 191944 | lestrange | Basic Home | 329.000 | SIM | 2.50 % | 1.704 |
| 191941 | lestrange | Basic Home | 329.000 | SIM | 2.50 % | 1.704 |

| 191902 | lestrange | Basic Home | 329.000 | SIM | 2.50 % | 1.704 |

+--------+------------+------------+---------+-------------+--------+-----------+
```
I added the estimated HIVE token price to each order. The result table is sorted by the estimated HIVE price. This allows to check which offer has currently the best price. The HIVE price is calculated by using the last token price which is returned by the API.
### nfttrades
```
Usage: hiveengine nfttrades [OPTIONS] [SYMBOL]
Returns the trades history
Options:
-a, --account TEXT Buy with this account (defaults to "default_account")
```
This shows the last trades for a NFT symbol.
