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: NEW DELETED CHANGED Old File, New File 11 19 4 old.pmccabe/./Makefile pmccabe/./Makefile 214 10 39 old.pmccabe/./cparse.c pmccabe/./cparse.c 463 0 0 NEWFILE pmccabe/./decomment.c 147 4 39 old.pmccabe/./dmain.c pmccabe/./dmain.c 10 0 0 NEWFILE pmccabe/./dmain.h 407 0 0 NEWFILE pmccabe/./getopt.c 48 0 0 NEWFILE pmccabe/./getopt.h 9 18 12 old.pmccabe/./gettoken.c pmccabe/./gettoken.c 18 18 15 old.pmccabe/./io.c pmccabe/./io.c 175 43 20 old.pmccabe/./nmain.c pmccabe/./nmain.c 194 11 22 old.pmccabe/./pmccabe.c pmccabe/./pmccabe.c 42 0 20 old.pmccabe/./pmccabe.h pmccabe/./pmccabe.h 0 1318 0 old.pmccabe/./test/langMode.c DELETED 24 0 0 NEWFILE pmccabe/./test006/Grapher.H 620 0 0 NEWFILE pmccabe/./test006/Handler.H 442 0 0 NEWFILE pmccabe/./test006/NodeArc.H 764 0 0 NEWFILE pmccabe/./w/parser.C 95 0 0 NEWFILE pmccabe/./w/tokens.h 4 0 0 NEWFILE pmccabe/./x.sh 3687 1441 171 TOTAL DIAGNOSTICS
There aren't many at this time. 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. AUTHOR
