1 简介

SLOC（Source Lines of Code)，是一套用于统计项目中用到的多种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。

1. Ada (.ada, .ads, .adb)
2. Assembly (.s, .S, .asm)
3. awk (.awk)
4. Bourne shell and variants (.sh)
5. C (.c)
6. C++ (.C, .cpp, .cxx, .cc)
7. C shell (.csh)
8. COBOL (.cob, .cbl) as of version 2.10
9. C# (.cs) as of version 2.11
10. Expect (.exp)
11. Fortran (.f)
12. Haskell (.hs) as of version 2.11
13. Java (.java)
14. lex/flex (.l)
15. LISP/Scheme (.el, .scm, .lsp, .jl)
16. Makefile (makefile) - not normally shown.
17. Modula-3 (.m3, .i3) as of version 2.07
18. Objective-C (.m)
19. Pascal (.p, .pas)
20. Perl (.pl, .pm, .perl)
21. php (.php, .php[3456], .inc) as of version 2.05
22. Python (.py)
23. Ruby (.rb) as of version 2.09
24. sed (.sed)
25. SQL (.sql) - not normally shown.
26. TCL (.tcl, .tk, .itk)
27. 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
...
SLOC    Directory       SLOC-by-Language (Sorted)
1929666 tensorflow      cpp=1313054,python=571706,java=15935,ansic=10758,
                        pascal=8380,sh=8343,objc=1172,cs=168,perl=150

1016    top_dir         python=1008,sh=8
130     tools           sh=130


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).
