昨天在VBS吧看到一個(gè)精華帖《VBS代碼格式化工具》，是用C++寫的，區(qū)區(qū)VBS代碼格式化，就不要?jiǎng)贑++大駕了吧，用VBS實(shí)現(xiàn)VBS代碼格式化工具不是更自然么？

網(wǎng)上的VBS代碼大部分都沒有縮進(jìn)，新手不知道要縮進(jìn)，高手縮進(jìn)了被某些個(gè)垃圾網(wǎng)站采集以后也就沒有了縮進(jìn)，還有以一些博客貼吧也會(huì)把縮進(jìn)給吃掉。除了縮進(jìn)之外，由于學(xué)VBS的大部分都是學(xué)批處理出身，代碼風(fēng)格還是跟寫批處理一樣難看。其實(shí)一般情況下用VbsEdit 5.2.4.0自帶的代碼格式化功能就行了，沒有必要重復(fù)造輪子。只不過(guò)VbsEdit 5.2.4.0在格式化帶有冒號(hào)的代碼時(shí)不是很理想，加上我已經(jīng)很久沒有寫過(guò)像樣的VBS腳本了，所以還是決定造一下輪子。

2011年12月27日更新：在線VBScript代碼格式化工具VbsBeautifier

因?yàn)榇a比較長(zhǎng)，所以貼在文章的最后，下面是VBS代碼格式化工具的效果演示：

格式化前的VBS代碼：

代碼如下:

ON ERROR RESUME NEXT:Set fso = CreateObject("Scripting.FileSystemObject"):X=0:T=true:WhiLe T

Input=Inputbox("Filename Lowercase Batch Convertor"&vbcrlf&vbcrlf& _

"Please input the destination folder name. e.g. C:\Webmaster"&vbcrlf&vbcrlf& _

"Note: Do NOT add '\' in the end of folder name!","FLowercase Convertor","C:\")

iF Input="" then:Msgbox"Folder name is empty!",48,"Error!":T=true:else T=false:end If:wend

Msgbox"All files names of "&Input&" will be converted to lowercase now...",64,"Note"

fold(Input):Msgbox"Done! Total "&X&" file(s) were converted to lowercase.",64,"Done"

sub fold(Path):SET f=fso.GetFolder(Path):Set rf = fso.GetFolder(Path).files:Set fc = f.SubFolders

foR EACh fff in rf:lcf1=LCase(fso.GetAbsolutePathName(fff))

fso.MoveFile fff, lcf1:X=X + 1:next:for EacH f1 in fc:fold(f1)

Set file=fso.GetFolder(f1).files:fOR EACh ff iN file:lcf=LCase(fso.GetAbsolutePathName(ff))

fso.MoveFile ff,lcf:NEXT:NEXT:END sub

格式化后的VBS代碼：

?1234567891011121314151617181920212223242526272829303132333435 On Error Resume NextSet fso = CreateObject("Scripting.FileSystemObject") X = 0 T = TrueWhile T Input = InputBox("Filename Lowercase Batch Convertor" & vbCrLf & vbCrLf & _ "Please input the destination folder name. e.g. C:\Webmaster" & vbCrLf & vbCrLf & _ "Note: Do NOT add '\' in the end of folder name!","FLowercase Convertor","C:\") If Input = "" Then MsgBox"Folder name is empty!",48,"Error!" T = True Else T = False End IfWEnd MsgBox"All files names of " & Input & " will be converted to lowercase now...",64,"Note"fold(Input) MsgBox"Done!
