EVE CREST access tool

Project description

# Prest

## Summary

Prest is a Python library for accessing EVE Online's CREST API.

## Installation

From [pip](

pip install eveprest

## Use

### Initialization

from prest import Prest

prest = Prest()

### Attributes and calls

* Calling
* on `prest.Prest`: reload the base URI data
* `prest()` -> the same `prest.Prest`
* on `prest.APIElement`: navigate to a new page
* `` -> `prest.APIElement`
* Getting attribute by text or item by index
* from `prest.Prest`: return a data subset or navigate to a new page
* `` -> `str`, `int`, `float`, `prest.APIElement` of data subset, `prest.APIElement` to new page
* from `prest.APIElement`: return a data subset
* `` -> `str`, `int`, `float`, `prest.APIElement`

To reduce typing, `prest.Prset.__getattr__` combines the functionality of `prest.APIElement.__getattr__` and `prest.APIElement.__call__` so that calls can be made like `` instead of `prest().foo`.

If you wanted to access the X position of the Kimoto constellation, the call would be:


From the [base url]( "constellations" is a root-level dictionary item with a "href" item, which can be called to navigate to [that page](

From there, the `.items` attribute dives into the `items` dictionary key and then a `find` method is used to get an element from the list of dictionaries (you could loop through the items yourself, but `find` is for convenience). This dictionary has a "href" element, so call the attribute to navigate [there](

Now on the final page, access the "position" key and finally its "x" key, which is `-134996400468185440`.

### Examples

1. Market types -> page count


2. "Jump Through a Wormhole" opportunity description

prest.opportunities.tasks().items.find(name='Jump Through a Wormhole').description

3. Jita 4-4 moon name


### Using the cache

When you make a call to ``, the root CREST URI data stored locally will be checked for an expired cache timer (the root URI's data is loaded when instantiating a new `prest.Prest` object, you don't need to do it manually). If it's expired, the root URI will be gotten anew and cached. This is similar for `` - if all of `foo`, `bar`, and `baz` were dictionaries with `'href'` keys that pointed to new pages, each would use the cache to retrieve the page, only making a new request to CREST if the local copy of the page is either non-existent or expired.

However, when getting attributes from a page, like ``, neither `bar` or `baz` on the page will be using the cache. Thus, in order to make the same call multiple times over a period of time and using the cache, either make the full `` call again, or save the last-called element as a local variable and call that:

foo =


# later:

### Authentication

Accessing the authenticated parts of CREST is done through authenticating Prest:

from prest import *

prest = Prest(client_id='', client_secret='', client_callback='')
auth = prest.authenticate(code)

In the code above, `get_authorize_url` returns a URL to redirect a web app client to so they can log into EVE's SSO. Once they've redirected back to your web application, pass the code in the returning URL from EVE to the `authenticate` call and assign the resulting `prest.AuthPrest` object.

This `prest.AuthPrest` object works the same as the unathenticated `prest.Prest` object: use attributes and calls to navigate and load CREST data, respectively.

Example of accessing a character's location:
