foreign-colors.taq

$ java -jar taq.jar foreign-colors ^german.color_query shade=Wasser

Running query color_query in german scope 
Parameters [foreign-colors, ^german.color_query, shade=Wasser]
color(shade=Wasser, red=0, green=255, blue=255)

Description

foreign-colors.taq demonstrates using a context list to translate a selection value. The context list is named “colors”

$ list<term> colors

There are 2 foreign scopes “german” and “french”, the names reflecting the languages to be translated. The “color_query” query of each scope takes a foreign language color name and returns the red-green-blue color components. Each scope has a “colors” axiom with foreign color values and the terms named in English.

axiom german.colors 
  ( aqua,     black,     blue,   white )
  {"Wasser", "schwarz", "blau", "weiß" }

The “color” select declaration maps the color by name to the color components. The first name in it’s header is “colors”, which being the name of a context list, will cause the select to perform translation according to the current scope.

select color  ( colors, Red, Green, Blue)
