print-messages

print-messages

Because making console.log easier to read and write is a double edge sword of time saving.

npm install print-messages

pm = require('print-messages');

Besides normal stuff like colored log, warn, success, and error methods, we have 2 more

• node
• promise

---

Node.js usually has callbacks like function(err, result){ ...

user.save(function(er,res){
    // String will be green or red depending on er, res
    pm.node('user.save results...', er, res);
})

---

Promises are becoming popular

var promiser = require('when');
willSucceed = promiser.defer()

pm.promise('promise result is(green or red): ', willSucceed.promise);
willSucceed.resolve("resolve is green");

// or we could have done this
//willSucceed.reject("reject is red");

---

#Examples

####Basic log, warn, success, error

pm.log('log me', 'log me long tim');
pm.warn('warn me', 'warn me long tim');
pm.success('success me', 'success me long tim');
pm.error('error me', 'error me long tim');

Node callbacks

// Node callbacks are usually (err, res)
pm.node('some failing save message', 'That failed', null);
pm.node('some success message', null, {
  results: 'are cool'
});

Promises

promise = require('when');
    
willSucceed = promise.defer();
willFail = promise.defer();
    
pm.promise('This is for a promise', willSucceed.promise);
willSucceed.resolve('That works');

pm.promise('Whereas this is for a promise', willFail.promise);
willFail.reject('That fails');

Patch Notes

v0.3.0

Updated from coffee-script to js.

Added newLine [=true] and blankLine [=true] options to determine if arguments should be on new lines and if each log should be preceeded by a blank line. Both false looks like this:

pm.newLine = false;
pm.blankLine = false;

Added a way to change colors.

pm.colors.error = 'magenta';
pm.colors.success = 'blue';
pm.init()

v0.2.2

Ensured at least 1 printed message will appear, even if first arg is an object

v0.2.0

Added pm.node_cb for user.save(pm.node_cb('My message might be green or red'))

v0.1.0

Added pm.crash and pm.crash_cb for promise.otherwise(pm.crash) or promise.otherwise(pm.crash_cb('with message'))

Added pm.error_cb, pm.success_cb, pm.warn_cb, pm.log_cb for user.save().error(pm.error_cb('it failed)); // logs: 'it failed'.red, errors...
