Colorful console log, with line number via v8 callSite.

• colourful style
• fast get line number with callsite
• show date
• replace default console

npm install cclog

if true show colors in log, default tty.isatty()

only show log with the setting level or above. avariable params: 'debug', 'info', 'warn', 'error', 'none'

return a new logger object. cclog is also a logger object;

options.filename the path of log file, default null.

options.stdout the stream use for stdout.

options.stderr the stream use for stderr.

stdout fmt see util.format

stderr fmt see util.format

stdout inspect obj

stderr if obj is Error instance then log the stack, else inspect it.

db.get('foo', cclog.intercept('callback foo', handle));

alias

db.get('foo', function(err, data) {
  if(err) {
    cclog.error('callback foo', err);
  } else {
    cclog.info('callback foo', err, data);
  }
  handle && handle(err, data);
}

deprecated use cclog.intercept() instead. stderr generate a function to handle error.

fs.mkdir('/foo', function(err) {
  if(err) cclog.error(err);
});

use cclog.ifError to get a closure, NOTE always use cclog.

// WRONG
var ifError = cclog.ifError;
fs.mkdir('/foo', ifError);

// right
fs.mkdir('/foo', cclog.ifError);

replace console functions with cclog, console.log(msg) will work like cclog.log(msg)

restore original console functions, but keep the function that doesn't present in original console.
