FetchCode: Utilities to fetch code from purls, URLs and version control repos.

FetchCode is a library to reliably fetch code via HTTP, FTP and version control systems. It can work using plain HTTP and FTP URLs, as well as Package URLs and version control (VCS) URLs as used in Python pip and as specified in SPDX Package Download Location

Homepage and support: https://github.com/nexB/fetchcode

Why FetchCode?

It is surprisingly difficult to have a simple API to consistently fetch code from package repositories, version control repositories and APIs: each site and each package manager has its own unique and peculiar ways. FetchCode goal is to abstract all these details and make it easy to fetch things reliably.

Development installation

Clone the repo:

git clone https://github.com/nexB/fetchcode

Then install all the requirements using:

configure --dev

Running tests

To run test suite use:

pytest -vvs

Usage

Fetch a code archive and get a fetchcode.fetch.Response object back:

>>> from fetchcode import fetch
>>> f = fetch('https://github.com/nexB/fetchcode/archive/ab65b2e645c889887227ea49eb3332d885fd0a54.zip')
>>> f.location
'/tmp/tmp_cm02xsg'
>>> f.content_type
'application/zip'
>>> f.url
'https://github.com/nexB/fetchcode/archive/ab65b2e645c889887227ea49eb3332d885fd0a54.zip'

Fetch some package metadata and get a fetchcode.packagedcode_models.Package object back:

>>> from fetchcode import package
>>> list(package.info('pkg:rubygems/files'))
[Package(type='rubygems', namespace=None, name='files', version=None)]
