RSM can perform a source code metrics differential analysis between
two
dated baselines. The -w"create ..." mode creates a file which contains each file and its LOC
metrics by the date of the -w processing. This mode creates a file by a name in the
form of rmMMDDCCYY.dat where MM is the month, DD the day, CC the century and YY is the
year.
Work files may be generated using source code change differentials. This is accomplished by using the -wd mode when creating the work files. This mode characterizes each source code file and store this information in a directory with the work file. All reports are changed to a differential mode expressing code change versus the default RSM reports showing net size metrics change of the baseline.
When this mode completes, the work file is copied to a file called workfile.dat. You may also use the -wx option to extract baseline differentials between
two work files.
Work file extraction reports the baseline differential expressing code change if the -wd mode is used with the -w"create ..." and -w"x ..." options.
-wb
Show on the report the numeric factors used to calculate the productivity
metrics.
-w"create c:\baseline directory"
Creates the work files named workfile.dat and a date formatted file named
rm11222001.dat for the date 11-22-2001. The baseline root directory must be stated so that RSM can relate all files to this baseline. This is an absolute path, not a relative path, to the top directory of your code tree.
-wD
Deterministic mode for differentials showing the format
of the code differential file when using -w"create ...".
-wd
Perform individual file differentials for lines of code
metrics. The normal baseline metrics comparison mode
shows a file is modified when a net change in LOC size is
made to the size of the file in LOC. This switch identifies
lines in a file that have changed from one source file to
another. This mode create a differential file for each
source file whereby being time and space intensive. A
modified file will show lines that have been added, delete
and modified. Each differential file name is shown using
the -wv option. This option is used with -w"create ..." and -w"x ...".
-we
This parameter causes RSM to not process equal files
between the old and new baselines.
-w"File dat usernamedfile.dat"
This option allows the user to specify the name of the generated work
file. The date formated file is replaced by the user specifed file.
i.e. rsm -w"create c:\project" -w"File dat c:\project\mywork.dat" -r"h,cpp,java c:\project"
-w"File cfg user_work_config.dat"
This option allows the user to specify a configuration file for the baseline
metrics differential report. This report is controlled by the file rsm_workdiff.cfg
or a user specified file. The following link will take you to a typical
baseline metrics differential file user_work_config.cfg.
i.e. rsm -w"File cfg c:\project\user_work_config.cfg" -w"x rm07022002.dat,
rm08232002.dat"
-wm
This parameter causes RSM to not process modified files
between the old and new baselines.
-wn
This parameter causes RSM to not process new files between
the old and new baselines.
-wp
Report the productivity of the programmers based on the metrics
differential between baselines and the time differential between the two
files work .dat files.
-wr
This parameter causes RSM to not process removed files
between the old and new baselines.
-ws
Show code differential details for each file showing line
number, removed or modified, and line type.
-wv
Verbose mode for metrics differential file names when using -wd and -wc.
-w"x older_workfile.dat, newer_workfile.dat"
Work Analysis Extraction from Work Analysis Files. This mode extracts
the work analysis differential between two work analysis files. These
work analysis files must be based on the same code tree. The reported
metrics will show LOC information based upon the time differential between
these two files.
i.e. rsm -w"x <ancestor file>, <current file>"
rsm -H -O"diff.htm" -w"x baseline1.dat, baseline2.dat"
rsm -A -O"diff.csv" -w"x rm11101997.dat, rm11141997.dat"
