Using Python dependencies in Sparrow plugins

Latest version of Sparrow has brought a new feature for those who would like to write sparrow plugins using Python language.

Now you can declare a Python/Pip dependencies with the help of requirements.txt file:

$ cat requirements.txt
http==0.02 

Let’s create a simple plugin to make http requests using hackhttp python library.

$ cat story.py
import hackhttp
from outthentic import *

url = config()['url']
hh = hackhttp.hackhttp()

code, head, html, redirect_url, log = hh.http(url)

print code

$ touch story.check

$ cat sparrow.json
{
    "name" : "python-sparrow-plugin",
    "description": "test sparrow plugin for python",
    "version" : "0.0.4",
    "url" : "https://github.com/melezhik/python-sparrow-plugin"
}

Now let’s upload the plugin to SparrowHub and give it a run:

$ sparrow plg upload
sparrow.json file validated ...
plugin python-sparrow-plugin version 0.000004 upload OK

$ sparrow plg install python-sparrow-plugin

upgrading public@python-sparrow-plugin from version 0.0.3 to version 0.000004 ...

And finally if you prefer to get things done by Perl6/Sparrowdo use this piece of code as starting point:

$ cat sparrowfile

my $url = 'http://example.com';
task-run "http get $url", 'python-sparrow-plugin', %( url => $url );
