SYNOPSIS

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.
