新版本的Qu

以前寫過一篇qu的介紹blog（見http://m.shnenglu.com/cyt/archive/2005/10/08/579.html）。
現在語言已經出到1.21.03版本。當然，其進步也已經不少。主頁在：http://centrin.net.id/~marc/

1、語言對象豐富了很多。因為不記得以前有多少種了，所以也說不清究竟多了多少。不過現在看內部支持的類型列表，明顯比以前多了。例如Socket、Thread、Weak、Proc等等。

2、支持嵌入HTML，例如：

pragma?html

options?=?[foo:1,?bar:2,?baz:3]

<FORM?ACTION="/foo"?METHOD="POST">

????<SELECT?NAME="choice">

????for?k,?v?in?options

????????<OPTION?VALUE=v>(\k)</OPTION>

????;;

????<INPUT?TYPE="submit"?VALUE="Send">

????</SELECT>

</FORM>?

3、提供了 JIT engine，就是用上次介紹過 GNU Lightning。換句話說，代碼可以翻譯為匯編代碼，可以在x86, SPARC and PowerPC等機器上執行。變成匯編，其性能提高多少可想而知。qu自己也列出了其性能比較：http://centrin.net.id/~marc/performance.html

4、提供一種validators技術，動態類型語言的數據類型靈活多變，所以類型校驗顯得比較重要。例如：

sub?Message?(x)

????return?x?is?String?and?x?and?not?x.isspace???x.capitalize?:?false

;;

sub?hello?(s:?Message)

????println?('Hello?',?s)?#?guess?what?it?prints!

end?sub

Message看起來好像是一個函數的樣子，但它可以用來驗證變量的類型。保證傳入hello函數的參數s，必須要滿足Message(s)返回true。

5、靈活的語法，特別是支持lambda語法。喜歡ruby的估計也會喜歡這個

f?=?sub?(x)?return?x.len?>?3?;;

f?=?lambda?(x)?x.len?>?3

f?=?{|x|?x.len?>?3}

f?=?{|x|?yield?i?for?i?in?x}

反正主頁上列出了很多很多吸引人的Features。不過具體實用性如何，我就不知道了。暫時看不到有什么著名的成功案例。不過語言真的是越來越吸引了。

“4、提供一種validators技術”

語法很明顯是參考了BASIC :)

感覺上就是大雜燴，估計作者是把各種語言自己喜歡的部分都綜合起來。不過反而顯得沒有自己的風格。回復更多評論

java,ruby,php,python,perl,tcl在web開發也比較完善了,如果讓人再學一個Qu，恐怕有點力不從心. 不過也許在特殊應用中能應用. 回復更多評論
