Text-to-Redis

Author: Ignacio Lago @ignlg
Version: 1.2

A handy tool to convert a batch of Redis commands for mass insert/exec.

It converts an input text with Redis commands to an output text in Redis
Protocol.

Example input:

  ; This is a comment
  SADD key1 value2 value3
  SADD key2 value4 value5
  ; Another comment

The output can be pipelined to the redis-cli:
cat redis-commands.txt | coffee text-to-redis.coffee | redis-cli --pipe

Or saved to a file:
cat redis-commands.txt | coffee text-to-redis.coffee > redis-mass-insert.redis

Redis Protocol: http://redis.io/topics/protocol
Redis Mass Insert: http://redis.io/topics/mass-insert

CHANGELOG:
  1.2: - Better support for comments
