Developer's productivity plugin for Smalltalk/X IDE.


SmallSense is a set of tools that speed up development and make Smalltalk programming even more fun. Features:

  • Code-completion -- a fast code completion system for Smalltalk using both static and runtime type inference.
  • Syntax-driven editing -- a nice little feature that helps you with editing and formatting the code, all syntax- and formater-preferences aware!
  • Instant static analysis -- to detect & fix common errors and code smells as you type

There are many more features already on the TODO list :-) Besides, SmallSense provides (limited) support for Java anf Groovy as well (to be used together with STX:LIBJAVA)


Stock Smalltalk/X (aka official version)

Following instructruction are for stock Smalltalk/X 6.2.5 as downloaded from [eXept].

1. Remove old SmallSense: remove directory /stx/goodies/smallsense. Smalltalk/X may come with it's own version/fork of SmallSense.

2. Check out SmallSense:

hg clone stx/goodies/smallsense

3. Compile it (optional):


make -C /stx/goodies/smallsense -f Makefile.init

On Windows:

cd stx\goodies\smallsense && bmake

4. Load it: to load it into an IDE, evaluate:

Smalltalk loadPackage:'stx:goodies/smallsense'

You may want to add the above to your startup script (`$HOME/.smalltalk/p_$USER.rc) so SmallSense will be loaded automatically when you start Smalltalk/X. You may also want to turn on method swizzling there.

Smalltalk/X jv-branch

There's no need to install SmallSense into Smalltalk/X jv-branch as it is loaded automatically when you start Smalltalk/X.


After installing and loading SmallSense, you may want to configure it. To do so, open system settings and go to ToolsSmallSense.
