baseLanguage.sugar

Language sugar for JetBrains MPS.

Inspired by Ruby & Python goodies.

Features

Simplistic string format

string message = "My name is %s, I am %d years old" % "Isaac Newton", 18;
assert message equals "My name is Isaac Newton, I am 18 years old";

Inline 'if'

int t = 0; 
t = 5 if t > 0; 
assert t == 0;

Inline 'unless' - inverted if

int t = 0; 
t = 5 unless t == 0; 
assert t == 0;

Usage

Goto Settings->Global Libraries, create "baseLanguage.sugar" library, pointing to a directory with baseLanguage.sugar.jar and baseLanguage.sugar-src.jar. MPS is somewhat clunky when it comes to libraries, so restart might be needed.

Add "baseLanguage.sugar" to your list of used languages.

To convert existing statement into "unless/if" statement place your cursor AFTER ending semicolon and start typing respective keyword.
