Reddit Processing Utils

Wrapper for Reddit API including batch processing and events/broker services

Goals

• Create scalable services that can listen on multiple subreddits and gather data concurrently
• Also allow fast batch processing of multiple threads, gathering data as needed
• Setup broker interface to connect with and allow multiple topics to be processed

Install Instructions

1. Get:

go get -u github.com/dillonmabry/reddit-processing-utils/...

2. Create localbot.agent file with your corresponding Reddit credentials:

user_agent: "Reddit-Comments-Utils:<version> (by /u/<user>)"
client_id: "<client_id>"
client_secret: "<client_secret>"
username: "<username>"
password: "<password>"

Run Instructions

Event Listener (Requires RabbitMQ/PostGres setup)

Modify/run .bat files as needed with default settings OR Run manually:

Event listener

export GRAW_BOT_AGENT=localbot.agent && go run src/events/exec/main.go --subreddits <subreddits comma separated> --search <search text inside post body> --queue <queue to publish per amqp>

Consumer

go run src/consumer/exec/main.go --queue <queue to consume per amqp>

Can set environment variables as needed:

• GRAW_BOT_AGENT: location of your graw config
• AMQP_DEFAULT_BROKER: your broker url amqp://:@localhost:5672
• AMQP_DEFAULT_EXCHANGE: amqp exchange
• POSTGRES_CONN: Postgres connection info

Batch

To export multiple subreddit threads based on a regex "form style" search into multiple .csv files:

export GRAW_BOT_AGENT=localbot.agent && go run src/batch/exec/main.go csv --subreddit OMSA --threads a73ni1,8m2anv --headers "Application Date,Decision Date,Education,Test Scores,Experience,Recommendations,Comments"

To export multiple subreddit threads based on a regex "form style" search into a single .csv format: (Notice the -m merge flag)

export GRAW_BOT_AGENT=localbot.agent && go run src/batch/exec/main.go csv --subreddit OMSA --threads a73ni1,8m2anv --headers "Application Date,Decision Date,Education,Test Scores,Experience,Recommendations,Comments" -m

To export multiple subreddit threads into a single .txt format:

export GRAW_BOT_AGENT=localbot.agent && go run src/batch/exec/main.go txt --subreddit OMSA --threads a73ni1,8m2anv

Regex "Form Style" Search

To use the regex search, a Reddit thread must have replies that can be searched/filtered. For example, the following "form" would work:

Application Date: 02/16/2019

Status: Won!

Comments: Hey!

Replace the HEADER: sections with the headers you need

Tests

Docker Compose

To use docker compose:

1. Create your localbot.agent file inside of src/events/exec/
2. Run:

docker-compose build
docker-compose up

The services for rabbitmq, postgres, consumer, and producer builds should initialize

Obviously you should update your credentials using secrets and not use "admin:admin" for everything
