代码统计开源工具 SLOCCount

1 简介

SLOC（Source Lines of Code)，是一套用于统计项目中用到的各类源代码总行数的工具。此外，SLOC 还会估算出开发该项目所需的工作量、所需人员和时间等项目成本（基于 COCOMO 模型）。目前 SLOC 支持的语言多达 27 种。

• Ada (.ada, .ads, .adb)
• Assembly (.s, .S, .asm)
• awk (.awk)
• Bourne shell and variants (.sh)
• C (.c)
• C++ (.C, .cpp, .cxx, .cc)
• C shell (.csh)
• COBOL (.cob, .cbl) as of version 2.10
• C# (.cs) as of version 2.11
• Expect (.exp)
• Fortran (.f)
• Haskell (.hs) as of version 2.11
• Java (.java)
• lex/flex (.l)
• LISP/Scheme (.el, .scm, .lsp, .jl)
• Makefile (makefile) - not normally shown
• Modula-3 (.m3, .i3) as of version 2.07
• Objective-C (.m)
• Pascal (.p, .pas)
• Perl (.pl, .pm, .perl)
• PHP (.php, .php[3456], .inc) as of version 2.05
• Python (.py)
• Ruby (.rb) as of version 2.09
• sed (.sed)
• SQL (.sql) - not normally shown
• TCL (.tcl, .tk, .itk)
  -Yacc/Bison (.y)

2 安装

• 源码安装： tar.gz
• RPM 包安装： rpm 包
  sudo rpm -ivh sloccount-2.26-1.i386.rpm
• Debian:
  sudo apt-get install sloccount

3 用法

语法：sloccount directory_name

示例（以 tensorflow 源码为例）

$ sloccount tensorflow-master
...

Totals grouped by language (dominant language first):
cpp:        1385668 (69.06%)
python:      575513 (28.68%)
java:         15935 (0.79%)
ansic:        10758 (0.54%)
sh:            8577 (0.43%)
pascal:        8380 (0.42%)
objc:          1172 (0.06%)
cs:             168 (0.01%)
perl:           150 (0.01%)
lisp:            37 (0.00%)




Total Physical Source Lines of Code (SLOC)                = 2,006,358
Development Effort Estimate, Person-Years (Person-Months) = 586.89 (7,042.71)
 (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 6.04 (72.46)
 (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 97.20
Total Estimated Cost to Develop                           = $ 79,281,247
 (average salary = $56,286/year, overhead = 2.40).
