Package Exports
- yalm
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (yalm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

options
You can set desired loglevel...
log.setLevel('debug'); // default: 'info'. possible values: 4, 'debug', 3, 'info', 2, 'warn', 1, 'error', 0, 'silent'... and you can disable printing of timestamps, severity and colors
log.setTimestamp(false);
log.setSeverity(false);
log.setColor(false);aliases
made for humans...
log('...'); // is an alias of log.info('...');
log.warning('...'); // is an alias of log.warn('...');
log.err('...'); // is an alias of log.error('...');change styling
if you want another timestamp format overwrite the log.ts function...
log.ts = function () {
// seconds since epoch
return '' + Math.floor((new Date()).getTime() / 1000);
};... if you want to change the severity strings overwrite log.map properties
log.map.debug = 'DEBUG:';
log.map.info = 'INFO:';
log.map.warn = 'WARNING:';
log.map.error = 'ERROR:';license
