search for: ref_id

Here is my weird problem. Two models like following: Lexeme id:int name:string Structure id:int ref_id:string meta_id:int Lexeme can have many structure records through foreign key ''ref_id'' in the structures table. And these structure records belonging to one lexeme differs between each other using meta_id. And if Lexeme has structures, then there must be a top_struct whose struct...

...ther purposes. Changes were: * Changed the syntax for compatibility with a future extension mechanism. The first character in the curly braces must be a colon, optionally followed by a space: {: ref .class #id} The old syntax was `{ref .class #id}`. For ALDs, the new syntax is: {:ref_id: key=val .class #id } instead of: {ref_id}: key=val .class #id Converters that don't use this syntax may just ignore everything which is in curly braces and starts with ":". For regexp-based interpreters, this is the regular expression to get rid of this stu...
