Reading the Results
The main (or index) page consists of a table of pairs of files that
have similar code, sorted by the size of the code that is considered
the same in both files. The format of a table entry is
Lines Matched is approximately the number of lines of code that
matched. Each
file is also given a percentage score, which is the
the percentage of the code in one file considered
to match code in the other file. For both measures, higher
numbers mean more code matches.
For each pair of matches there is a page with information on
particular passages that match. The window is divided into
three frames: one for a table of all passages that matched, and
one each for the source code of the two files.
The table of passages has the format
| filename1 (%) | thermometer1 | filename2 (%)
| thermometer2
|
|---|
| - | 88-99 | | 119-131 |
|
where each row gives a range of line numbers from file1 and file2 that are considered to be
the same, along with a "thermometer" (not shown) graphically depicting how much of all the code in the file is
matched by this passage (e.g., a thermometer that is half filled in indicates that this one passage is about half the code in the file). The line range is a hyperlink to the
appropriate passage in the corresponding program. The passage has the
color of the small rectangle at the left-hand edge of the row. Highlighted passages are hyperlinked;
clicking on a passage sets the focus in the other program frame to the matching passage.
