Sidef provides full access to its parser, which allows to inspect all declarations, including variables, classes and methods.

<lang ruby>var program = <<'EOT'

func foo { }

func bar { }

foo(); foo(); foo()

bar(); bar();

EOT

var parser = Parser.new # initialize a new parser

parser.parse_script( code => program ) # parse the code

var data = Perl.to_sidef(parser{:vars}{:main}).flatten

data.sort_by { |v| -v{:count} }.first(10).each { |entry|

if (entry{:type} == :func) {

say ("Function `#{entry{:name}}` (declared at line",

" #{entry{:line}}) is used #{entry{:count}} times")

}

}</lang>

{{out}}

<pre>

Function `foo` (declared at line 1) is used 3 times

Function `bar` (declared at line 2) is used 2 times
