In addition, D2D offers functionality for using older revisions. This might be useful for testing whether an error also occurs for older code versions. The old revisions are referred to by the commit-ID (also termed SHA or sha-hash value). These commit-IDs are hexadecimal strings. They occur on github in long and short versions. Click on "commit" for selecting a specific commit version and selecting the corresponding ID.

Downloading of the old version. The paths have to be set to the download folder by hand.

Evaluating a specific command using an old version. This function can be used to compare the outcome of several versions. Download and setting of paths are done automatically.

revision_path = arGetOldRevision(sha)

addpath([revision_path,filesep,'d2d-',sha,filesep,'arFramework3'])

which arInit % check whether the path is set properly
