memesql5

This is prototype Python/Postgres implementation of Memelang v4. This Python script receives Memelang queries, converts them to SQL, executes them on a Postgres database, then returns results as a Memelang string.

File	Purpose
app.py	Command-line interfaces
conf.py	Postgres database configuration
db.py	Postgres database helper functions
parse.py	Encode / decode Memelang strings into meme-token lists
readme.md	Project overview (this file)
setup.py	Python package settings

Installation

Example Python Usage

import memesql

# Convert a Memelang string to a meme token list
memes = memesql.decode('student=JohnAdams =')

# Convert a meme token list to an SQL query
sqlstr, params = memesql.select(memes)

# Return result Memelang string from database for a Memelang query
result_meme_str = memesql.dbget('student=JohnAdams =')
