[--] directories
DESCRIPTION
sloccount counts the physical source lines of code (SLOC) contained in descendants of the specified set
of directories. It automatically determines which files are source code files, and it automatically
determines the computer language used in each file. By default it summarizes the SLOC results and
presents various estimates (such as effort and cost to develop), but its output can be controlled by
various options.
If you give sloccount a list of two or more directories, the counts will be broken up according to that
list. There is one important limitation: the basenames of the directories given as parameters must be
different, because those names are used to group summary information. Thus, you can't run "sloccount
/usr/src/hello /usr/local/src/hello". This limitation only applies to parameters of sloccount -
subdirectories descended from the top directories can have the same basename.
If you give sloccount only a single directory, sloccount tries to automatically find a reasonable
breakdown for purposes of reporting (so it'll produce a useful report). In this case, if the directory
has at least two subdirectories, then those subdirectories will be used as the breakdown. If the single
directory contains files as well as directories (or if you give sloccount some files as parameters),
those files will be assigned to the directory "top_dir" so you can tell them apart from other contents.
Finally, if there's a subdirectory named "src", then that subdirectory is again broken down, with all the
further subdirectories prefixed with "src_". Thus, if directory "X" has a subdirectory "src", which
contains subdirectory "modules", sloccount will report a separate count for "src_modules".
sloccount normally considers all descendants of these directories, though unless told otherwise it
ignores symbolic links.
sloccount is the usual front-end of the package of tools named "SLOCCount". Note that the name of the
entire package has capital letters, while the name of this front-end program does not.
sloccount will normally report estimates of schedule time, effort, and cost, and for single projects it
also estimates the average number of active developers. These are merely estimates, not etched in stone;
you can modify the parameters used to improve the estimates.
OPTIONS
--version Report the version number of SLOCCount and immediately exit. This option can't be usefully
combined with any other option.
--cached Do not recalculate; instead, use cached results from a previous execution. Without the
--cached or --append option, sloccount automatically removes the data directory and recreates
it.
--append Do not remove previous calculations from the data directory; instead, add the analysis to the
current contents of the data directory.
--datadir directory
Store or use cached data in the given data directory; default value is "~/.slocdata".
--follow Follow symbolic links.
--duplicates
Count all duplicates. Normally, if files have equal content (as determined using MD5 hash
values), only one is counted.
--crossdups Count duplicates if they occur in different portions of the breakdown. Thus, if the top
directory contains many different projects, and you want the duplicates in different projects
to count in each project, choose this option.
--autogen Count source code files that appear to be automatically generated. Normally these are
excluded.
--multiproject
The different directories represent different projects; otherwise, it's assumed that all of
the source code belongs to a single project. This doesn't change the total number of files
or SLOC values, but it does affect the effort and schedule estimates. Given this option,
effort is computed separately for each project (and then summed), and the schedule is the
estimated schedule of the largest project.
--filecount Display counts of files instead of SLOC.
--wide Display in the "wide" (tab-separated) format.
--details Display details, that is, results for every source code file.
--effort F E
Change the factor and exponent for the effort model. Effort (in person-months) is computed
as F*(SLOC/1000)^E.
--schedule F E
Change the factor and exponent for the schedule model. Schedule (in months) is computed as
F*(effort)^E.
--personcost cost
Change the average annual salary to cost.
--overhead overhead
Change the overhead value to overhead. Estimated cost is computed as effort * personcost *
overhead.
--addlang language
Add a language not considered by default to be a ``language'' to be reported. Currently the
only legal values for language are "makefile", "sql", and "html". These files are not
normally included in the SLOC counts, although their SLOCs are internally calculated and they
are shown in the file counts. If you want to include more than one such language, do it by
passing --addlang more than once, e.g., --addlang makefile --addlang sql.
--addlangall
Add all languages not normally included in final reports.
NOTES
As with many other programs using Unix-like options, directories whose names begin with a dash (``-'')
can be misinterpreted as options. If the directories to be analyzed might begin with a dash, use the
double-dash (``- -'') to indicate the end of the option list before listing the directories.
BUGS
Filenames with embedded newlines (in the directories or their descendants) won't be handled correctly;
they will be interpreted as separate filenames where the newlines are inserted. An attacker could
prevent sloccount from working by creating filenames of the form /normal/directory ... NEWLINE/dev/zero.
Such filenames are exceedingly rare in source code because they're a pain to work with using other tools,
too. Future versions of sloccount may internally use NUL-separated filenames (like GNU find's -print0
command) to fix this.
There are many more languages not yet handled by SLOCCount.
SLOCCount only reports physical source lines of code. It would be very useful if it could also report
logical lines of code, and perhaps other common metrics such as McCabe's complexity measures and
complexity density (complexity/SLOC for each function or procedure).
