Add some color to your Capistrano scripts
The beauty of ruby makes it simple to add some colorful syntax highlighting to log messages that are displayed in your capistrano scripts. Here’s a chunk of code I added to my utility.rb file that is included by my capfile that performs the magic.
def colorize(text, color_code)
"#{color_code}#{text}\033[0m"
end
def red(text); colorize(text, "\033[31m"); end
def boldred(text); colorize(text, "\033[1;31m"); end
def green(text); colorize(text, "\033[32m"); end
def boldgreen(text); colorize(text, "\033[1;32m"); end
def yellow(text); colorize(text, "\033[33m"); end
def boldyellow(text); colorize(text, "\033[1;33m"); end
def blue(text); colorize(text, "\033[34m"); end
def boldblue(text); colorize(text, "\033[1;34m"); end
def purple(text); colorize(text, "\033[35m"); end
def boldpurple(text); colorize(text, "\033[1;35m"); end
def cyan(text); colorize(text, "\033[36m"); end
def boldcyan(text); colorize(text, "\033[1;36m"); end
def white(text); colorize(text, "\033[37m"); end
def boldwhite(text); colorize(text, "\033[1;37m"); end
def inform(text); green(text); end
def highlight(text); boldgreen(text); end
def warning(text); yellow(text); end
def alert(text); red(text); end
def section(text); "\n\n#{"*" * 50}\n#{text}\n#{"*" * 50}";
Now by utilizing the wrapper methods like this:
task :testconfig do
logoutputDir = Logging.initialize("#{$deployDir}/logs", $envNameName, $envNameNum)
Logging.info inform("*" * 75)
Logging.info inform(" Starting... ")
Logging.info " Env: " + highlight('development')
Logging.info " Date: " + highlight(Time.now.to_s)
Logging.info " User: " + highlight('jsmith')
Logging.info " Logs Dir: " + highlight('/tmp/projectX/log')
Logging.info inform("*" * 75)
Logging.info inform(".. informational message ...")
Logging.info warning(".. warning message ...")
Logging.info alert(".. alert message ...")
Logging.info highlight(".. highlighted message ..")
Logging.info inform("*" * 75)
Logging.info inform(" Done! ")
Logging.info " Date: " + highlight(Time.now.to_s)
Logging.info " Dist: " + highlight('/tmp/projectX/dist')
Logging.info inform("*" * 75)
end
You'll get pretty output like this:
