sloc

sloc is a simple tool to count SLOC (source lines of code)

sloc

Create stats of your source code:

• lines of code
• lines with comments
• lines with block comments
• lines with single-line comments
• lines mixed up with source and comments
• empty lines
• physical lines

Supported outputs

sloc provides a set of output formatters:

• CSV
• JSON
• Commandline table

Install

To use sloc as an application install it globally:

sudo npm install -g sloc

If you're going to use it as a Node.js module within your project:

npm install --save sloc

Browser

You can also use sloc within your browser application.

Link sloc.js in your HTML file:

<script src="lib/sloc.js"></script>

sloc is also available via bower:

bower install sloc

Note: You need to compile the coffee-script files yourself. If you want to use a precompiled bower package, you can run

bower install sloc-bower

Usage

CLI

sloc [option] <file>|<directory>

Options:

-h, --help                  output usage information
-V, --version               output the version number
-e, --exclude <regex>       regular expression to exclude files and folders
-f, --format <format>       format output: json, csv, cli-table
    --format-option [value] add formatter option
-k, --keys <keys>           report only numbers of the given keys
-d, --details               report stats of each analzed file
-a, --alias <custom ext>=<standard ext> alias custom ext to act like standard ext (eg. php5=php,less=css)

e.g.:

$ sloc src/

               Empty :  245
 
Number of files read :  10

or

$ sloc --details \
       --format cli-table \
       --keys total,source,comment \
       --exclude i18n*.\.coffee \
       --format-option no-head src/

Node.js

Or use it in your own node module

var fs    = require('fs');
var sloc  = require('sloc');
 
fs.readFile("mySourceFile.coffee", "utf8", function(err, code){
 
  if(err){ console.error(err); }
  else{
    var stats = sloc(code,"coffee");
    for(i in sloc.keys){
      var k = sloc.keys[i];
      console.log(k + " : " + stats[k]);
    }
  }
});

Browser

var sourceCode = "foo();\n /* bar */\n baz();";
 
var stats = window.sloc(sourceCode,"javascript");

Contribute an new formatter

1. Fork this repo

2. add the new formatter into src/formatters/ that exports a method with three arguments:

   1. results (object)
   2. global options (object)
   3. formatter specific options (array)

3. add the formatter in src/cli.coffee

4. open a pull request

Grunt

If you'd like to use sloc within your grunt process you can use grunt-sloc.

Install it:

npm install grunt-sloc --save-dev

and use it:

grunt.loadNpmTasks('grunt-sloc');

For more details navigate to the project site.

Gulp

sloc is also available for gulp.

Install gulp-sloc:

npm install --save-dev gulp-sloc

and use it:

var sloc = require('gulp-sloc');
 
gulp.task('sloc', function(){
  gulp.src(['scripts/*.js']).pipe(sloc());
});

Atom

You can use atom-sloc to display stats of the current file in the statusbar.

And there is another great atom package called line-count that gives you a more detailed report showing line counts broken down by file, directory, and file type for all files in the project.
