Meme Generator

This is the second project in Udacity's Intermediate Python Nanodegree program.

This project will create a meme by overlaying a quote with an author's name at a random position over an image.

The user can customize the output by providing an image, a quote, and an author's name. If any of these are omitted, one will be randomly provided.

Project Setup

Clone the project repository.

git clone https://github.com/johnshea/nd303_project_02_meme_generator.git

Change into the project directory.

cd nd303_project_02_meme_generator

Create a virtual environment.

python3 -m venv env

Activate the virtual environment.

source env/bin/activate

Change into the src directory.

cd src

Install the required project dependencies.

pip install -r requirements.txt

Create the required output directories.

mkdir static
mkdir tmp

Follow the steps below for running this as a command line application or as a Flask application.

NOTE: When finished, to exit the virtual environment run:

deactivate

To Run The Project From The Command Line

From the command line, run:

python3 meme.py

Additional runtime configuration options:

usage: meme.py [-h] [-p PATH] [-b BODY] [-a AUTHOR]

Create a meme

optional arguments:
  -h, --help            show this help message and exit
  -p PATH, --path PATH  path to an image file
  -b BODY, --body BODY  quote body to add to the image
  -a AUTHOR, --author AUTHOR
                        quote author to add to the image

To Run The Project As A Flask Application

From the command line, run:

$ export FLASK_APP=app.py
$ flask run --host 0.0.0.0 --port 3000

Open your browser. Open http://localhost:3000/ NOTE - Generated memes will be saved in directory static.

Modules

Module MemeGenerator

class MemeEngine

Dependencies: PIL, random, os

A class to generate a meme.

Method make_meme will generate a meme from optionally provided arguments. This method will return the path of the generated meme.

Example:

>>> from MemeGenerator import MemeEngine
>>> meme = MemeEngine('./output')
>>> meme.make_meme('./_data/photos/dog/xander_3.jpg', 'Go big or go home!', 'Slugger', width=250)
'./output/8943911.png'
>>> 

Module QuoteEngine

class IngestorInterface

Dependencies: abc, QuoteModel, typing

An abstract base class upon which concrete ingestor classes are realized.

An ingestor class is a concrete subclass which will parse file types based on their file extension.

Concrete classes must implement:

• abstract method parse. This method parses the provided file and returns a list of QuoteModel objects.
• override class variable allowed_extensions which is a list of file extensions types which is can parse. Example: allowed_extensions = ['txt']

class Ingestor

Dependencies: IngestorInterface, TextIngestor, DocxIngestor, CSVIngestor, PDFIngestor, QuoteModel, typing

A general class that is capable of ingesting multiple file types by delegating to individual ingestor classes.

A call to method parse will returns a list of QuoteModel objects.

Example:

>>> from QuoteEngine import Ingestor
>>> print(Ingestor.parse('./_data/DogQuotes/DogQuotesTXT.txt'))
[<QuoteModel author='Bork' body='To bork or not to bork'>, <QuoteModel author='Stinky' body='He who smelt it...'>]
>>> 

class CSVIngestor

Dependencies: IngestorInterface, QuoteModel, typing, pandas

A concrete class to ingest a csv file.

A call to method parse will return a list of QuoteModel objects.

File Format:

body,author
Line 1,Author 1
Line 2,Author 2

Example:

>>> from QuoteEngine import CSVIngestor
>>> print(CSVIngestor.parse('./_data/DogQuotes/DogQuotesCSV.csv'))
[<QuoteModel author='Skittle' body='Chase the mailman'>, <QuoteModel author='Mr. Paws' body='When in doubt, go shoe-shopping'>]
>>> 

class DocxIngestor

Dependencies: IngestorInterface, QuoteModel, typing, docx

A concrete class to ingest a docx file.

A call to method parse will return a list of QuoteModel objects.

File format:

"Line 1" - Author 1
"Line 2" - Author 2

Example:

>>> from QuoteEngine import DocxIngestor
>>> quotes = DocxIngestor.parse('./_data/DogQuotes/DogQuotesDOCX.docx')
>>> print(quotes)
[<QuoteModel author='Rex' body='Bark like no one’s listening'>, <QuoteModel author='Chewy' body='RAWRGWAWGGR'>, <QuoteModel author='Peanut' body='Life is like peanut butter: crunchy'>, <QuoteModel author='Tiny' body='Channel your inner husky'>]
>>> 

class PDFIngestor

Dependencies: IngestorInterface, QuoteModel, typing, subprocess, random, tempfile, os

A concrete class to ingest a pdf file.

A call to method parse will return a list of QuoteModel objects.

File format:

"Line 1" - Author 1
"Line 2" - Author 2

Example:

>>> from QuoteEngine import PDFIngestor
>>> quotes = PDFIngestor.parse('./_data/DogQuotes/DogQuotesPDF.pdf')
>>> print(quotes)
[<QuoteModel author='Fluffles' body='Treat yo self'>, <QuoteModel author='Forrest Pup' body='Life is like a box of treats'>, <QuoteModel author='Bark Twain' body='It's the size of the fight in the dog'>]
>>>

class TextIngestor

Dependencies: IngestorInterface, QuoteModel, typing

A concrete class to ingest a txt file.

A call to method parse will return a list of QuoteModel objects.

File format:

"Line 1" - Author 1
"Line 2" - Author 2

Example:

>>> from QuoteEngine import TextIngestor
>>> print(TextIngestor.parse('./_data/DogQuotes/DogQuotesTXT.txt'))
[<QuoteModel author='Bork' body='To bork or not to bork'>, <QuoteModel author='Stinky' body='He who smelt it...'>]
>>>

class QuoteModel

Dependencies: None

A data class to hold a quote which contains a quote body and quote author.

Example:

>>> from QuoteEngine import QuoteModel
>>> quote = QuoteModel("Body of Quote", "Author name")
>>> print(quote)
<QuoteModel author='Author name' body='Body of Quote'>
>>>
