超实用:Mac OS X下各种文件编码的转换方法

贫困的富七代 134

前言:

现时你们对“苹果电脑怎么写java代码的文件夹名称”大致比较看重,我们都想要知道一些“苹果电脑怎么写java代码的文件夹名称”的相关知识。那么小编也在网上收集了一些关于“苹果电脑怎么写java代码的文件夹名称””的相关知识,希望我们能喜欢,同学们快快来了解一下吧!

何曾几时本猫还在windows下编码的时候,那时ruby的源代码的编码格式都是gbk啊!导致N多中文显示为乱码。后来无奈写了个转换代码从gbk编码转为utf-8格式的小工具:

#!/usr/bin/ruby#tool 4 gbk encoding to utf8  src_path = $*[0]unless src_path	puts "usage #{$0[2..-1]} gbk_file"	exit 1end dir_name,base_name = File.split(src_path)dst_path = dir_name << '/u8_' << base_namef_src = File.open(src_path,"r:gbk")f_dst = File.open(dst_path,"w:utf-8") f_src.each_with_index do |line,i|	line.encode!("utf-8")	if(i < 2)		#line.gsub!(/gbk/,"utf-8") if(line =~ /^#[ ]*coding*/)		line.gsub!(/gbk/,"utf-8") if(line =~ /^*coding*/)	end	f_dst.puts lineend f_src.closef_dst.close`chmod +x #{dst_path}`

虽说ruby足够小巧,但也是要十几行代码才能搞定啊,而且这只能转换一种格式.

大救星iconv

再后来,我发现mac系统下竟然自带iconv这个好东东啊:

ICONV(1) Linux Programmer's Manual ICONV(1)NAME iconv - character set conversionSYNOPSIS iconv [OPTION...] [-f encoding] [-t encoding] [inputfile ...] iconv -lDESCRIPTION The iconv program converts text from one encoding to another encoding. More precisely, it converts from the encoding given for the -f option to the encoding given for the -t option. Either of these encodings defaults to the encoding of the current locale. All the inputfiles are read and converted in turn; if no inputfile is given, the standard input is used. The converted text is printed to standard output. The encodings permitted are system dependent. For the libiconv imple- mentation, they are listed in the iconv_open(3) manual page.

我们来试一下,创建一个utf-8格式的文本:

路人甲:最近又多学了德语,现在懂中文,英语和德语啊

猫猫:靠,我早精通十几门语言了

路人甲:擦,我才不信

猫猫:汇编语言,C语言,C++语言,C#语言,ruby语言,javascript语言...

路人甲:...

用iconv转换为gbk格式(或者反向转换也可以):

apple@kissAir: ruby_src$iconv -f UTF-8 -t GBK ex_u8.txt > ex_gbk.txt

apple@kissAir: ruby_src$cat ex_gbk.txt

èè?????????羫ͨʮ??????????

·?˼ף??????ҲŲ???

èè?????????,C????,C++???ԣ?C#????,ruby????,javascript????...

·?˼?:...apple@kissAir: ruby_src$

虽说是乱码,但的确是货真价实的gbk格式啊!

最后来看一下iconv到底支持多少种编码格式,貌似是超多的哦:

结尾的话

最后说点题外话,夸一下UNIX系统的整体性和统一性,这种统一性带来学习成本的急剧下降,而且让人很有成就感。比如我在ruby中知道正则表达式最后加i表示忽略大小写,我有次用grep查找的时候发觉也要忽略大小写查找,你猜猜我用神马选项:grep -i xxx,就是这么统一,这么和谐。windows下可以吗?哦,对了windows下人家不玩console,人家都玩窗口...
