Structural code comparison is an approach that allows you to compare sources. Where code compare tool detects the closely similar lines that to provide better comparison result. For this such tools cannot determine similarity between two lines if there is a little change in the both lines.

You will not need third party software to compare and merge versions.Ĭomparing lines content using Online Code CompareĪny normal comparison tool uses algorithm based on search for strictly equal strings. The editor allows you to change any of the two panes. The file comparison window has two open files in the two aforementioned panes.
When the three ways comparison takes place in regular way, the left pane is compared to the middle one and then the middle one is compared to the right pane to finally produce the output.

Researchers have built clone detectors that do something like this, but the combinatorics make this very expensive to execute, and the research prototypes scaled poorly.Code compare is an Online tool that designed to find and compare the code diff that are located in the different lines with Inline or Side by Side results. I don't know of tools that will actually find "equivalent" code (reversed conditionals), etc. These latter tend to give better answers, because unlike the token detectors, they can use the language structure of the computer source code as a guide. Token based detectors do this for edits which replace just variable names or constants.Ībstract-syntax tree (AST) based detectors do this for edits involving larger chunks, such as expressions, statements, insertions, deletions, et. If you want to see the details of the copying for copy-past-edit code, you need a clone detector that finds "parameterized" clones. What these won't do is find code that is copy-paste-edited they will find boilerplate copy-paste-unchanged code likely wrapped around the copy-past-edited stuff. To decide grossly if there is lot of copying, you only need to match source lines, and there are a variety of exact source-line clone detectors out there. You can do this by running a clone detection tool. What you really want to do is see if there is code cloned (copied) across the two projects (both projects consisting of possibly large sets of files).
