A system includes a source code repository which stores source code entries, which include instructions in a programming language for performing computing tasks. A style repository stores a style profile. Each style profile includes predefined style features associated with formatting characteristics of the stored source code entries. A source code analyzer receives a source code which includes instructions in the programming language for performing a computing task. Style features of the source code are determined. The style features include characteristics of a format of the source code. The source code analyzer determines whether the style features correspond to predefined style features indicated by a style profile. If this is the case, the source code is stored in the source code repository. If this is not the case, storage of the source code is prevented.
