I intend to write up my findings, but haven’t gotten around to it yet. I do have slides for a talk for this project though: https://speakerdeck.com/ddfreyne/simulating-a-cpu-with-ruby
(I’m mostly speaking out of my experience with VisualWorks, a commercial Smalltalk implementation, but other implementations are similar.)
I would greatly recommend everyone to give Smalltalk a try. The IDEs are pretty ugly and cumbersome, but don’t let that put you off. Get a feeling of the minimalism of the programming language and the pure form of object orientation. Dig through the code of the standard library — it’s quite easy — and check out the implementations of TrueClass, FalseClass, BlockClosure etc.
Unfortunately, many parts of the Smalltalk IDEs are horribly outdated and make Smalltalk a very poor choice of environment to use for production code.
Smalltalk lives in its own little world, and the tools that you’d normally use during day-to-day development are integrated in the IDE, and there is virtually no possibility of using external tools. The text editors are pretty bad, and you can’t use vim or emacs or Sublime Text. The Smalltalk VCSes are particularly horrible. For version control, you need to use systems such as Monticello or Store, both of which make me cringe just thinking about them again.
I also feel that Smalltalk coders get locked in into their environment. Many Smalltalkers that I have met are quite unfamiliar with what is happening in the outside world. Most of them have never heard of git, for example (and quite a few did not know what Subversion was). When an interesting technology enters the Smalltalk world, people seem to rush to reimplement it in Smalltalk (yes, there is STON — Smalltalk Object Notation).
These were the main reasons why I quit my Smalltalk job. A sad decision, but one that was unavoidable in the long run.
Smalltalk is a nice language and has IDEs with some very nice features that I would love to see in other environments, but it is also severely lagging behind in many other areas. I would like the Smalltalk community to be more aware of what is happening outside and build bridges. Without that mindset, I feel Smalltalk will simply fade out completely.
Source: I used to be a professional Smalltalker for almost three years.
The reason for writing the article, however, is because I have seen the same mindless behaviour with other people as well.
If you say that you never randomly modify code in order to make it work (according to the tests), then that is great, and that is how every developer should work. However, my experience is that people who lack discipline (or face a looming deadline) tend to not take their time to properly reason about code and instead rely on the test suite to tell them whether code is right or not.
More importantly, I have also seen this happen in professional environments. A very large test suite is very useful, but it is absolutely not a catch-all safety net.
