Universal generator of computer code, in particular for translating computer languages

摘要

The generator of a computer code on the basis of an input specification source, that is a file (4), comprises at least the following parts: a front end (FE) unit which creates an intermediate file (6) by grammatical and syntactic analysis of the specification file wherein the intermediate file comprises a syntactic tree describing the data of the specification file so that each datum extracted from the specification file by the front end unit is associated with a node of the syntactic tree; an instructions file, that is a template (3), defining the programming rules associated with each node as a function of the code to generate, that is an output specification source (7); and a back end (BE), that is a coding unit, generating the output code (7) by reading the intermediate file and the syntactic tree. The back end (BE) unit reads a grammar file (5) describing the grammar of the language of the specification file (4). The front end (FE) unit decomposes the specification file (4) into logic elements which form the nodes of the syntactic tree according to a functional branching conformed to the specification file, and the logic elements are the data extracted from the specification file. The instructions file (3) comprises the programming pulse of the output code (7) associated with each logic element of a node, and the manner of applying a rule is associated with each node. The logic elements associated with nodes are interfaces, variables, constants, operations, and logic or mathematical functions. The output code (7) is a computer language. The front end (FE) unit is in communication with the specification file (4) of an input language, that is of a language to be translated into another language, and also with the grammar file (5). The grammatical analysis is effected in a standard manner. The intermediate file is, for example, written in ASCII code. The back end (BE) unit delivers the output specification file (7) comprising the translation of the input language into an output language such as C or ADA. The instructions file (3) is a function of the output code and is written by use of a language such as the templates description language (TDL).
