標(biāo)題: 對(duì)java代碼注釋的刪除 [打印本頁]

標(biāo)題: 對(duì)java代碼注釋的刪除
代碼注釋刪除，請(qǐng)高手幫忙

例如：ceshi.java

/**
* [email={@.en]{@.en[/email] Feature is father class of all the feature implementations, every feature
* hide, destroy.} [email={@.ja]{@.ja[/email] }
*
* [email={@.en]{@.en[/email] Feature is father class of all the feature implementations, every feature
* hide, destroy.} [email={@.ja]{@.ja[/email] skdjflsjdflkdjslfsjdkjflskdjfksjdlfjsldkjflksjdlkjflkjsldjflksjdsdf
* sdfdsfsdfsdfsdfsd }
*
* [email=*{@.ja]{@.ja[/email] jslkdjflkdsjlkfjldskjfkjdslfkjlsdkjflkdsjlkfjdslkjflkdsjlfkjsdlkfjslkdjflksjdlkfjsldkjfdf
* sdfsdfdsfsdfsdfsddfsdfsfdsdfsdfsdddddddddddddddddddddddddddddddddddddddd
* sdfdsfsf  }
*
* [email={@.en]{@.en[/email] Feature is father }
*
        public void hide(Hashtable paraTable) {
                currentFM.hideFeature(this, paraTable);
        }
}

規(guī)則為：1. 刪除掉 [email={@.ja]{@.ja[/email] 與 緊鄰下一個(gè) } 和 之間的內(nèi)容，包括這之間的描述。
          2. 刪除掉 [email={@.en]{@.en[/email] 與 緊鄰下一個(gè) } ，保留這之間的英文內(nèi)容。

希望得到的運(yùn)行結(jié)果為：

/**
* Feature is father class of all the feature implementations, every feature
* hide, destroy.
*
* [email={@Feature]Feature[/email] is father class of all the feature implementations, every feature
* hide, destroy.
*
* [email={@Feature]Feature[/email] is father
*
        public void hide(Hashtable paraTable) {
                currentFM.hideFeature(this, paraTable);
        }
}


先行謝過拉：）

帶 地址符號(hào) '@' 問題就出錯(cuò)了

不好意思啊，我不是編寫java的，自己寫了點(diǎn)代碼，呵呵

比預(yù)想的只多了一行，就像{ja jdskjfkds} 如果跨行的話，只保留一行。對(duì)吧？
下面是執(zhí)行的結(jié)果，非常感謝

不知道你的代碼格式規(guī)范不？
如果你能保證所有的只有一個(gè)*號(hào)的注釋行都頂在行首的話：


  2. perl -e '
  3. > while(<>){
  4. > $text .= $_;
  5. > }
  6. > $text =~ s/\{ja.*?\}//gs;
  7. > $text =~ s/\{en(.*?)\}/$1/gs;
  8. > $text =~ s/(\*\s*\n)+/$1/gs;
  9. > print $text;'
復(fù)制代碼
作者: lululau    時(shí)間: 2009-06-18 22:11
阿，不好意思，一般來說，對(duì)于正常的Java代碼，我的這個(gè)假設(shè)根本不成立阿
作者: lululau    時(shí)間: 2009-06-18 22:13

  2. perl -e '
  3. > while(<>){
  4. > $text .= $_;
  5. > }
  6. > $text =~ s/\{ja.*?\}//gs;
  7. > $text =~ s/\{en(.*?)\}/$1/gs;
  8. > $text =~ s/([ \t]*\*\s*\n)+/$1/gs;

回復(fù)的有點(diǎn)晚了，剛洗了個(gè)澡，把自己機(jī)器上的linux 虛擬調(diào)通，呵呵。
下面是我測(cè)試的結(jié)果：

正是期望的結(jié)果吧，感激阿
下來一定要好好學(xué)正則表達(dá)式了，我只會(huì)一般的操作。

老大，能否解釋一下這幾個(gè)命令
:a
N
/*\//!ba

N我知道是允許跨行的模式匹配

先謝謝
