因项目汇报，需要统计代码规模。
自然的想法是用Shell来统计各类文件(.php|js|css|html|xml|yaml)的代码规模
> find . -name "*.php" -exec grep -Ev "^$" {} \;|wc -l 75450 > find . -name "*.js" -exec grep -Ev "^$" {} \;|wc -l 36725 > find . -name "*.html" -exec grep -Ev "^$" {} \;|wc -l 17830 > find . -name "*.css" -exec grep -Ev "^$" {} \;|wc -l 4146 > find . -name "*.xml" -exec grep -Ev "^$" {} \;|wc -l 4349 > find . -name "*.yaml" -exec grep -Ev "^$" {} \;|wc -l 0
在sourceforge发现统计代码规模的好工具 cloc.pl。
引用下官方的简介
cloc counts blank lines, comment lines, and physical lines of source code in many
programming languages. Given two versions of a code base, cloc can compute differences
in blank, comment, and source lines. It is written entirely in Perl with no dependencies
outside the standard distribution of Perl v5.6 and higher (code from some external modules
is embedded within cloc) and so is quite portable. cloc is known to run on many flavors of
Linux, Mac OS X, AIX, Solaris, IRIX, z/OS, and Windows. (To run the Perl source version of
cloc on Windows one needs ActiveState Perl 5.6.1 or higher, Cygwin, or MobaXTerm with the
Perl plug-in installed. Alternatively one can use the Windows binary of cloc generated with
perl2exe to run on Windows computers that have neither Perl nor Cygwin.)
接下来介绍下如何使用cloc.pl来统计代码规模：
1).下载脚本
> wget http://nchc.dl.sourceforge.net/project/cloc/cloc/v1.56/cloc-1.56.pl
2).给脚本添加执行权限+x
> chmod +x cloc-1.56.pl
3).对项目源码打开
> tar zcvf itravel2.tar.gz itravel2
4).统计代码规模
> ./cloc-1.56.pl itravel2.tar.gz 595 text files. 594 unique files. 2507 files ignored. http://cloc.sourceforge.net v 1.56 T=4.0 s (148.0 files/s, 35279.8 lines/s) ------------------------------------------- Language files blank comment code ------------------------------------------- PHP 224 4018 9848 62685 Javascript 118 3570 3083 31469 HTML 215 574 2557 14820 XML 19 0 57 4292 CSS 16 160 473 3513 ------------------------------------------- SUM: 592 8322 16018 116779 -------------------------------------------
