Unofficial Python wrapper for official Hacker News API.

Installation
============
```python
pip install haxor
```
Usage
=====

### Import and initialization:
```python
from hackernews import HackerNews
hn = HackerNews()
```

### Items
Stories, comments, jobs, Ask HNs and even polls are just items with unique item id.

To query item information by id:
```python
item = hn.get_item(8863)
# >>> item.title
# 'My YC app: Dropbox - Throw away your USB drive'
# >>> item.item_type
# 'story'
# >>> item.kids
# [ 8952, 9224, 8917, ...]
```
Since most results are returned as integer IDs (like item.kids above), these results require further iteration.  Instead of doing this yourself, use the `expand` flag to get object-oriented, detailed item info by id:
```python
item = hn.get_item(8863, expand=True)
# >>> item.kids
# [<hackernews.Item: 9224 - None>, <hackernews.Item: 8952 - None>, ...]
# >>> item.by
# <hackernews.User: dhouston>
```

To query a list of Item IDs:
```python
items = hn.get_items_by_ids([8863, 37236, 2345])
# >>> items
# [<hackernews.Item: 8863 - My YC app: Dropbox - Throw away your USB drive>, <hackernews.Item:
# 37236 - None>, <hackernews.Item: 2345 - The Best Buy Scam.>]
```
Use the `item_type` filter to specifically select 'story', 'comment', 'job', or 'poll' items:
```python
items = hn.get_items_by_ids([8863, 37236, 2345], item_type='story')
# >>> items
# [<hackernews.Item: 8863 - My YC app: Dropbox - Throw away your USB drive>, <hackernews.Item: # 2345 - The Best Buy Scam.>]
```

#### Stories
The HN API allows for real-time querying for New, Top, Best, Ask HN, Show HN, and Jobs stories.

As an example, to get Item objects of current top stories:
```python
top_stories = hn.top_stories()
# >>> top_stories
# [<hackernews.Item: 16924667 - Ethereum Sharding FAQ>, ...]
```

#### Useful Item Queries

To get current largest Item id (most recent story, comment, job, or poll):
```python
max_item = hn.get_max_item()
# >>> max_item
# 16925673
```
Once again, use the `expand` flag to get an object-oriented, detailed Item representation:
```python
max_item = hn.get_max_item(expand=True)
# >>> max_item
# <hackernews.Item: 16925673 - None>
```

To get the x most recent Items:
```python
last_ten = hn.get_last(10)
# >>> last_ten
# [<hackernews.Item: 16925688 - Show HN: Eventbot – Group calendar for Slack teams>, ...]
```

### Users
HN users are also queryable.

To query users by user_id (i.e. username on Hacker News):
```python
user = hn.get_user('pg')
# >>> user.user_id
# 'pg'
# >>> user.karma
# 155040
```
Use the `expand` flag to get an object-oriented, detailed Item representation for User attributes:
```python
user = hn.get_user('dhouston', expand=True)
# >>> user.stories
# [<hackernews.Item: 1481914 - Dropbox is hiring a Web Engineer>, ...]
# >>> user.comments
# [<hackernews.Item: 16660140 - None>, <hackernews.Item: 15692914 - None>, ...]
# >>> user.jobs
# [<hackernews.Item: 3955262 - Dropbox seeking iOS and Android engineers>, ...]
```

To query a list of users:
```python
users = hn.get_users_by_ids(['pg','dhouston'])
# >>> users
# [<hackernews.User: pg>, <hackernews.User: dhouston>]
```

Examples
========

Get top 10 stories:
```python
hn.top_stories(limit=10)

# [<hackernews.Item: 16924667 - Ethereum Sharding FAQ>, <hackernews.Item: 16925499 - PipelineDB # v0.9.9 – One More Release Until PipelineDB Is a PostgreSQL Extension>, ...]
```

Find all the 'jobs' post from Top Stories:
```python
stories = hn.top_stories()
for story in stories:
    if story.item_type == 'job':
        print(story)

# <hackernews.Item: 16925047 - Taplytics (YC W14) is solving hard engineering problems in
# Toronto and hiring>
# ...
# ...
```

Find Python jobs from monthly who is hiring thread:
```python
# Who is hiring - April 2018
# https://news.ycombinator.com/item?id=16735011

who_is_hiring = hn.get_item(16735011, expand=True)

for comment in who_is_hiring.kids:
    if 'python' in comment.text.lower():
        print(comment)

# <hackernews.Item: 16735358 - None>
# <hackernews.Item: 16737152 - None>
# ...
# ...
```
