Abstract: Systems and methods for code caching are provided. A first indication of primary source code awaiting execution is received. A resource cache is checked for cached data corresponding to the primary source code. Upon a cache miss in the resource cache, a first executable code compiled from the primary source code is obtained. A secondary source code referenced in the primary source code is selected. A second executable code compiled from the selected secondary source code is obtained. The first executable code and the second executable code are serialized into serialized code. The serialized code is stored as cached data in the resource cache.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for the rapid presentations of versions. In one aspect, a method includes receiving a document that includes multiple versions of source code of a computer program, each version comprising lines, each distinct line represented once in the document and identifying every version in which the line appears. The method includes presenting a user interface that enables a user to select one of the versions. The method includes receiving a selection of a first version of the source code. The method includes extracting the content of the first version from the document based solely on the content in the document and without receiving additional information from the server system. The method also includes displaying the distinct lines that identify the first version and not displaying the distinct lines that do not identify the first version.
