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。
- 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
...
