NAME¶
codechanges - computes the amount of code changes between two code trees or
single files
SYNOPSIS¶
codechanges [-n] old-directory new-directory
codechanges [-n] old-file new-file
DESCRIPTION¶
codechanges recursively compares the two named directories (or files)
calculating new/deleted/changed lines, not including comments or blank lines,
in files which appear to be source files (C, C++, shell, and Makefiles). To
include comments and blank lines, use the
-n option.
APPLICATIONS¶
codechanges is purpose designed to measure the amount of code change
between milestones in a project's life. The following output is from two
stages, plus some artificial test cases, in the
pmccabe code stream:

BUGS¶
codechanges thinks it knows what source files are interesting and the
user may not agree with its choices. It's a script and should be easy to
modify. Ultimately this should probably be configurable.
codechanges uses a program called
decomment which guesses how to
de-comment a file based on its file name and it's not always perfect.
