# Twitter Follower Count History via Web Archives [![Build Status](https://travis-ci.org/oduwsdl/FollowerCountHistory.svg?branch=development)](https://travis-ci.org/oduwsdl/FollowerCountHistory)
Follower Count History is a Python module that collects Twitter follower count from the web archives using [MemGator](https://github.com/oduwsdl/MemGator) for a given Twitter handle. The module parses the follower count by identifying various CSS Selectors that match the follower count element on the historical Twitter pages for almost every major overhaul their page layout has gone through. The program collects all of the memento data points by default.

Since PyPi version 1.0.14, the FCH package is now platform independent. Pre 1.0.14 versions of FCH on PyPi are only compatible with Linux systems.

## Installation and Usage
### Dependencies
* Python 3
* bs4
* warcio
* requests
* pytest (used for testing purposes)
* pytz (used for testing purposes)
* R* (Optional: to create graph)

### Usage
```shell
$ git clone https://github.com/oduwsdl/FollowerCountHistory.git
$ cd FollowerCountHistory
$ pip install -r requirements.txt
$ ./fch/__main__.py [-h] [--st] [--et] [--freq] [--out]

### Docker

We have published a docker image at [oduwsdl/fch](https://hub.docker.com/r/oduwsdl/fch) with the tag 2.0, which can be used to run this tool as following:

```
$ docker container run --rm -it -v :/app -u $(id -u):$(id -g) oduwsdl/fch:2.0 [options]
```

Example of output being mapped to the current directory

```
$ docker container run --rm -it -v $PWD:/app -u $(id -u):$(id -g) oduwsdl/fch:2.0 --out --st=20200101000000 --et=20200331000000 --freq=2592000 joebiden
```

Example of docker command for generating follower graph

```
$ docker container run --rm -it -v $PWD:/app -u $(id -u):$(id -g) --entrypoint /bin/bash oduwsdl/fch:2.0
I have no name!@736a209b64d6:/app$ ./fch/__main__.py --freq=2592000 joebiden| Rscript twitterFollowerCount.R
```
### Options
```
Follower Count History (fch)

positional arguments:
thandle Enter a Twitter handle/ URL

optional arguments:
-h, --help show this help message and exit
--st Memento start datetime (YYYYMMDDHHMMSS)
--et Memento end datetime (YYYYMMDDHHMMSS)
--freq Sampling frequency of mementos (in seconds)
-f Output file path (Supported Extensions: JSON and CSV)
-v, --version Report the version of fch
```
* --st: Default is set to Twitter birth date (2006-03-21 12:00:00). It accepts the memento datetime in [RFC 8601](https://www.iso.org/iso-8601-date-and-time-format.html) fourteen digit variation.
* --et: Default is set to the current datetime. It accepts the memento datetime in [RFC 8601](https://www.iso.org/iso-8601-date-and-time-format.html) fourteen digit variation.
* --freq: Default is set to download all the mementos
* -f: Accepts JSON and CSV file paths for output. If no value is provided, output is returned to stdout in CSV format.

## Output

The program can generate output in JSON and CSV format. The -f option directs the output of CSV or JSON files to the supplied file path. By default, the module returns the outut in CSV format to the stdout.

* Output as CSV file
```shell
$ fch -f=joebiden.csv joebiden

```
## Fch group script
* To run the 'fchgrp.sh' script, pass a txt or csv file as a parameter
* Output defaults to 'output/' folder
* Can use the same parameters as fch to generate the same results
```shell
$ ./fchgrp.sh user.txt
```
* Setting output to 'newOutput/' for csv files using 'fchgrp.sh'
```shell
$ ./fchgrp.sh user.txt -f=newOutput/
```
## Generate D3 Stub
* GenerateD3Stub is a python script that uses generateGraph_base.js and index.html and csv data generated by fch.

* Usage: GenerateD3Stub functions by passing n number of csv filepaths as parameters. The file generated afterwards 'generatedGraphStub.html' will have the embeddable code for use.
```shell
$ cd html_generator; python generateD3stub.py csv1path csv2path ... csvnpath
```
* By default, the GenerateD3Stub will print the data passed to it in the console, so the user can verify the correct data is being passed.
