Ruby on Rails has created considerable buzz within the industry. However, for a huge variety of our clients this represents an inexplicable challenge bereason Ruby and Rails don’t necessarily integrate well through their significant existing investments in Java code/frameworks and also they require brand-new skill sets and training for their existing staff.

You are watching: Groovy on grails vs ruby on rails

Groovy and Grails have arised as rivals to Ruby and also Rails that tightly embrace the Java language and also platcreate. For example, while Grails duplicates many kind of ideas from Rails, it does so by leveraging existing frameworks such as Spring and also Hibernate to attain this.

It’s worth noting that from a deployment perspective, both Ruby on Rails (more especially JRuby on Rails) and Groovy/Grails deserve to be deployed as WAR documents in a JDK 1.4 container. So neither strategy requires radical alters to the underlying deployment and also operations setting. But it’s in the breakthrough area wbelow these framefunctions differ.

This article is an effort to discover the capabilities of both languperiods and frameworks and compare and also comparison their ideologies to difficulties. And while bias is inevitable, I’ll at leastern attempt to separate the factual information from my very own biased conclusions.

NOTE: Further Rails and Grails rivals outside the scope of this record include:

Ruby vs Groovy

RubyandGroovyare both dynamic langueras. The primary emphasis of this section is to compare the language level and typical library functions and also capabilities. However, some referrals to the added language specific framefunctions will certainly be unavoidable since they are periodically the ideal demonstrations of the capabilities of each language.

One point that I will save out of this section are certain comparisons between the Rails and also Grails framefunctions, considering that I will devote another entire section to that comparikid later.

Ruby Overview

Rubywas developed in 1993 and is a reflective, dynamic, object-oriented programming language. It combines syntaxation motivated by Perl via Smalltalk-favor object-oriented functions, and also additionally shares some attributes with Python, Lisp, Dylan, and CLU. Ruby is a single-pass construed language. Its official implementation is complimentary software composed in C.

Ruby currently lacks full assistance for Unicode, though it has partial support for UTF-8.

Groovy Overview

Groovywas produced in 2003 and is a dynamic language that was the first, and also currently only, JSR apverified language (JSR-241) other than Java for the JVM. Though to be fair, various other langueras choose Ruby autumn under the umbrella ofJSR-223Scripting for the Java Platdevelop, and also numerous other languperiods can compile to bytecode and run on the JVM.

Groovy has attributes found in Python, Ruby, and Smalltalk, but offers syntaxation similar to the Java programming language. Groovy’s similarities to Java and reliance on the JDK collection it acomponent from these other dynamic languperiods and also permit it to accomplish a level of integration through Java that has yet to be got to in other languages.

no assistance for continuationsno support for generators (I’d prefer to study this further–it appears you can kludge it, however can’t truly assistance it without continuations)Groovy uses a different syntax than Java forforloops. Thus, many valid Java code that would otherwise also be valid Groovy code ends up with compilation errors and also need to either reprimary Java or be ported to Groovy’s syntax.Groovy has the quirk of being able to optionally use parenthesis for approach calls through parameters, however requiring them for techniques via no parameters (unless you usage the hack of naming the technique getMethod to trick Groovy right into reasoning it’s a property). (This quirk is actually an outcome of Groovy’s tight embracing of the existing JavaBean’s standard.)

Stack traces

Stack traces are lengthy and illegible. The reason for this is that making a dynamic contact in Groovy adds an average of somewright here in between 6 and 12 calls to the stack. So what could be a reasonable 20 line stack map in “normal” Java ends up as a 200+ line stack map in Groovy. And what’s worse, you most likely don’t treatment around the majority of the stack (it would certainly be nice if tright here was a straightforward method to filter out that crud or at leastern hide it). Here’s an example from a tiny script I created to contact a web company (which btw is as easy as this in Groovy):
