Pumptweet 2.1

Description:

pumptweet 2.1

PumpTweet
A Python script that cross posts from a Pump.io server to Twitter.

Overview
If you aren’t familiar with pump.io, take a look
at https://microca.st/. Try it out and see what you think! This script
is for people already using a pump.io service (like microca.st, but
there are many others, and you can run your own).
There are many different kinds of activities. Here, we look for notes,
which are like regular blog entries. We find a note, shorten it, make a
URL to the original, and tweet it. In other words, we’re cross-posting
from pump.io to Twitter.
When you compose a note, you choose the recipients. This script will
cross-post your note if it’s To: Public or CC: Public. Posts
that aren’t sent to Public are ignored. Other pump activities
(comments, likes, etc.) are excluded. It’s not obvious how they would be
of interest on Twitter.
This program is designed to be run as a cron job on a regular basis.

Example
Pump notes can be of any length, but tweets are limited to 140
characters. This program crops notes either (1) at the first line break
or (2) as close as it can to 140 characters while still leaving room for
a link to the original note. Here are some examples.
Example pump #1.
Have a great weekend, everyone!
Example tweet #1. The URL is a link to the original note.
Have a great weekend, everyone! http://ur1.ca/fislx
Example pump #2.
I have a technical question about cooling fans.

My processor on my new machine is an i7. I'm using a SilverStone AR-01 heat sink. The heat sink is...
Example tweet #2. Only the first line of the note is retained.

PyPI Installation
To start with, you need Python. Python 3.4 and 3.5 have been tested and
work. Older versions probably don’t.
It is easiest to install from
PyPI. First, make a
virtualenv. The virtualenv is nice because it means software you
install here won’t interfere with anything else on the system. Also, if
you find something is wrong or you’re otherwise unhappy, you can delete
the pumptweet directory.
$ cd
$ mkdir pumptweet
$ virtualenv pumptweet
$ cd pumptweet
$ source bin/activate
(pumptweet)$ pip install pumptweet
Assuming no errors showed up, you’ve installed pumptweet. The next
step is to configure it.

Source Installation

Browse: https://dperkins.org/git/gitlist/pumptweet.git.
Clone: https://dperkins.org/git/public/pumptweet.git.
GitHub: https://github.com/dper/pumptweet.git.

If you want to make custom modifications, consider a git install.
These instructions are for a Debian system. Other Linux and Unix
distributions should be similar. First, get the source code and put it
in a virtualenv.
$ cd
$ git clone https://github.com/dper/pumptweet
$ virtualenv pumptweet
$ cd pumptweet
$ source bin/activate
The command prompt should now begin with (pumptweet). You may also
need to install some dependencies, including
PyPump and
python-twitter.
(pumptweet)$ pip3 install pypump
(pumptweet)$ pip3 install python-twitter

Configuration
In order to use the script, create a file called PumpTweet.ini that
looks something like this.
[pump]
username =

[twitter]
key =
secret =
token =
token_secret =

[history]
recent =
published =
All of the values in [pump] and [twitter] must be filled in, but
the two entries in [history] can be left blank. If you fail to fill
in the top two sections, you’ll get some kind of error when running the
script. For convenience, a file called PumpTweet.ini.blank is
included. Copy that file or the above text to PumpTweet.ini and fill
in the necessary sections.
Place the PumpTweet.ini filein the base installation directory. For
example, I installed pumptweet into ~/pumptweet earlier in this
document. My configuration file should be located at
~/pumptweet/PumpTweet.ini.

Configuring Pump
The script uses
PyPump
to communicate with pump servers. This assumes you already have a pump
account.
The first thing you need to do is put your username (which looks like an
email address) into the [pump] section of the ini file. Next, run:
$ cd pumptweet
$ source bin/activate
(pumptweet)$ ./pt.py
At this point, you’ll get a hyperlink to your pump server. Paste the
link into your browser to open a page where you can sign in and give the
application the necessary permissions. Paste the verifier back into the
prompt to continue. This is all you need to do for [pump].

Configuring Twitter
To get the client validated with Twitter, use your favorite web browser.
This assumes you already have a Twitter account.

Go to https://apps.twitter.com/ and sign in.
Click Create new app.
You need to give it a name (like pumptweet314), a description
(like A cross-posting script from Pump to Twitter.), and a
website (if you make a fork of pumptweet on GitHub, that would be a
nice URL, but anything is OK). Also check the box agreeing with their
terms and answer the CAPTCHA.
Click on the Settings tab. Change Access to
Read and Write. At the bottom of the screen, click
Update this Twitter application's settings.
Click on the Details tab. Near the bottom of the screen click
Create my access token.
Click on the Keys and Access Tokens tab. This screen should show
you the four values needed in the ini file. Copy and paste them.
That’s all you need to do for [twitter].

Running the script
To run the script, just call it. If you’re missing any dependencies
(like the ones documented above), you’ll find out about it here. If you
installed pumptweet from source, run it as follows.
(pumptweet)$ ./pt.py
If you installed it using pip, run it as follows.
(pumptweet)$ ./bin/pt.py
If everything is working, you should see something like the following.
In this example, there’s one new note and therefore one new tweet which
is posted to Twitter.

Updating history...
If you run the script a second time, it looks to see if there is
anything new since last time it ran. In the below example, it looks at
one post and stops, because that post isn’t any newer than what the
script handled last time around. Nothing is posted to Twitter.

For convenience, there is a bash script, pt.sh that does
virtualenv stuff for you. Call that script from the command line to
make sure it works. If you installed from source, run it as follows.
$ cd /home/me/pumptweet && pt.sh
If you installed using pip, run it as follows.
$ cd /home/me/pumptweet && ./bin/pt.sh

Cron and rate limits
Suppose you have installed the program in /home/me/pumptweet and
have tested it using pt.sh to confirm that all is in working order.
The next thing to do is to make a cron job (using crontab -e) like
the following. The following cron job runs every five minutes.
*/5 * * * * cd /home/me/pumptweet && ./pt.sh > /dev/null
For most users, there is no worry, but if you tend to write many notes
in a short amount of time, cross posting can be somewhat delicate.
Twitter has a rate limit, though I don’t know exactly what it is. This
script posts up to three tweets at a time. If you have written five
notes since the last time you called it, the newest three will become
tweets and the oldest two will be forgotten.
If you find that you write many notes and they’re being skipped, you can
change PumpTweet.py and post more than three at a time. But don’t
raise the value too high, or you might hit the Twitter rate limit, start
looking spammy to your Twitter followers, or both. A better approach
might be a more frequent cron job.

Errors
Identifying errors can be difficult. If the Pump or Twitter servers are
completely offline, you will get an obvious error message, but if
they’re partly offline, you might not. Similarly, if your login is
incorrect, you might see confusing error messages. If you’re not sure
what’s going wrong, you are encouraged to open an issue, contact the
developers, or post a message to the Pump network.

Testing
If you’re trying to modify the script or track down some other error,
you might want to do test runs. In that case, call the script as
follows, updating the directories according to where you installed it.
(pumptweet) $ pt.py --test
For the (very short) command line help documentation, use this command.
(pumptweet) $ pt.py --help

GNU social
GNU social has a Twitter-like API, and you
can use this script, with a few modifications, to cross-post from
Pump.io to GNU social.
[@sazius](https://pump.saz.im/sazius/note/jdTJx2pQRGiEDpB5eDlXEg) has
done so, and here is what he says.

It was quite easy: just add the parameter
base_url='https://your.gnu.social/api' to the call to
twitter.API() in twitter_login in PumpLogin.py. I guess
you could have that as a configurable parameter.
Next problem was to get the OAuth token from GNU Social, I used the
get_access_token.py script, but you have to add
?oauth_callback=oob to the REQUEST_TOKEN_URL, and of course
replace the Twitter API URLs with the one for GNU social.
