关于coffeescript
安装之前,要先安装一个node.js.
安装coffeescript: npm install -g coffeescript
卸载: npm uninstall -g coffeescript
今日之最新版： 2.7.0
语法像python,用缩进表示层次, 语法上也争取像Python,具有切片,范围,推导式,字符串插值#{变量名}等特点,比js优雅. 注释也是前面加 #.
对中文字串的支持也很完美.
它是翻译成javascript来运行的.翻译之后再解释执行.
直接运行coffee脚本：coffee aaa.coffee
coffee脚本翻译成js文件： coffee -c aaa.coffee
js文件直接执行 node aaa.js
一个有意思的小语言.

#coffee script 会编译到javascript使用.
#采用缩进表达层次,类似Python的精简,切片/范围都好用,可用JS的库,中文支持好,有意思CalcBaseYear=(y) ->b=0if y>0b=4elseb=-57while b>yb=b-60while b+60<=yb=b+60return bYearToTGDZ=(y)->tgArr=["甲","乙","丙","丁","戊","已","庚","辛","壬","癸"]dzArr=["子","丑","寅","卯","辰","巳","午","未","申","酉","戌","亥"]if y==0return ""tmpY=yif tmpY>0tmpY=tmpY-4elsetmpY=tmpY-3while tmpY<0tmpY=tmpY+60ti=tmpY % 10di=tmpY % 12 tg=tgArr[ti]dz=dzArr[di]return "#{tg}#{dz}"TGDZtoYear=(tgdz,baseyear)->if tgdz.length==0return 0tg=tgdz.substr(0,1)dz=tgdz.substr(1,2)strTG="甲乙丙丁戊已庚辛壬癸";strDZ="子丑寅卯辰巳午未申酉戌亥";ti=strTG.indexOf(tg)di=strDZ.indexOf(dz)m=0if ti>=dim=ti-dielsem=12+ti-direturn baseyear+m*5+tiTest=(x)->baseYear=CalcBaseYear(x)tgdz=YearToTGDZ(x)x2=TGDZtoYear(tgdz,baseYear)console.log "年份:#{x}, 干支记年:#{tgdz}, 甲子年:#{baseYear},复算为: #{x2}\n" #会自动换行,亦可不加\n.#console.log CalcBaseYear(-361)

Test(y) for y in years当然,无图无真相,也少不了运行结果展示.
