My ZSH Theme

agnoster.zsh-theme

A ZSH theme optimized for people who use:

  • Solarized
  • Git
  • Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

For Mac users, I highly recommend iTerm 2 + Solarized Dark

One-line detailed logging for Rails 3 (ActiveSupport::Notifications) and later
# Outputs this at warn log level:
# 1.2.3.4 GET /path 200 OK BlahController#action HTML 938.2 (DB 11.8, View 719.7) {params} {optional params from flash[:log]}
#
# Save as config/initializers/oneline_detailed_logging.rb. Consider
# decreasing the log level from "info" to "warn" (in production.rb) so
# the one-line log message replaces the standard request logs.
# override process_action to add 2 things to the payload:
# - remote IP
