Abstract

An object oriented program editor operative on a text source in a language having syntax properties having a lexical analyzer, a parser, a codeblock generator and a graphical user interface. The lexical analyzer identifies language tokens in the text source. The parser which is coupled to the lexical analyzer associates syntax properties with the tokens. The codeblock generator which is coupled to the parser, groups tokens into a tree of codeblocks. The graphical user interface receives and implements user modifications of the codeblocks in a manner consistent with the programming language. A system for generating source code in a program language with respect to an object model having a plurality of classes and relations among such classes having a class selection interface, an action selection interface and a source code generator. The class selection interface is used for user selection of a chosen class. The action selection interface is used for user selection of (i) an entity associated with the model, the entity being one of a class and an instance of a class, on which to perform an action and (ii) user selection of an action to be performed on the entity wherein the action to be performed is selectable from a set of possible actions, the set being determined by the entity selected. The source code generator is used for generating source code in the program language to cause the action to be performed on the entity, and associating such code with the chosen class.
