Abstract

Various technologies related to code remediation are presented. Code to be remediated can be annotated with language-independent annotations. From the annotations, remediated code in a particular language can be generated. A wide variety of change types can be supported. Automatic or custom remediation can be achieved. Custom remediation can provide a user with control over the remediation process via helpful user interfaces. Considerable efficiency improvements can be realized without surrendering control of the remediation process.

(a) receiving source code to be remediated in light of a regulation set affecting logic of the source code, wherein the source code is of a programming language;
(b) generating a plurality of language-independent annotations for the source code to be remediated, wherein the language-independent annotations are of a format having a grammar that forms an executable language and wherein the executable language comprises at least one change function and one or more parameters for the change function, wherein the annotations comprise:
an indication of a token representing a constant or a variable name appearing in the source code;
parameters comprising an indication of a change type associated with the token, an indication of a statement type associated with the token, and an indication of an impact location associated with the token;
and
an indication of a new value associated with the token;
(c) based on the language-independent annotations, outputting a language-independent analysis tree comprising breaking down the annotations into a set of patterns and sequentially arranging the patterns for translation, wherein the analysis tree comprises nodes specifying the indication of the token and the parameters;
and
(d) generating a remediated version of the source code, wherein generating the remediated version comprises translating the annotations, wherein the translating comprises consuming the parameters of the analysis tree, and applying the parameters from the annotations to the change function indicated in the annotations, wherein the change function generates source code comprising the new value associated with the token complying with the regulation set in the programming language of the source code and outputting lines of remediated source code in the programming language of the source code according to the plurality of language-independent annotations, wherein the remediated version complies with the regulation set.
