blocks|key|65533|text|正如其他人所提到的，没有一个是“盒子里的”。然而，当我们说“我们可以在集成开发环境中使用正则表达式吗？”时，我们需要小心，因为两个不同的人可能对which+regexp+they+want+to+see+supported有两种截然不同的想法。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|65534|因此，虽然有一种形式的regexp支持“内置”可能很好，但你必须意识到，当人们开始交换regexp食谱(与其他不使用Delphi的人交换)时，这将导致问题，并且无法弄清楚为什么一个人的有效regexp在Delphi中不是有效的regexp。|65535|那么它将是"regexp在Delphi中被破坏了“或者”为什么我们不能既支持XYZ的regexp又支持ABC的风格呢？“|65536|所以现在我想说的是，如果你能为Delphi找到一个支持这种风格的组件/库，那么选择哪个regexp适合你在某种程度上是一种优势。:)|65537|The+regular-expressions.info+site+also+has+a+page+specifically+about+Delphi+support+for+regexp。|65538|entityMap|0|LINK|mutability|MUTABLE|url|http://www.regular-expressions.info/refflavors.html|1|http://www.regular-expressions.info/delphi.html^0|20|13|0|0|0|0|0|0|2M|1|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]]|C|$]]|$1|D|3|E|5|6|7|Z|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|10|8|@]|9|@]|C|$]]|$1|H|3|I|5|6|7|11|8|@]|9|@]|C|$]]|$1|J|3|K|5|6|7|12|8|@]|9|@$A|13|B|14|1|15]]|C|$]]|$1|L|3|-4|5|6|7|16|8|@]|9|@]|C|$]]]|M|$N|$5|O|P|Q|C|$R|S]]|T|$5|O|P|Q|C|$R|U]]]]

There is not one "in the box", as mentioned by others. However, we need to be careful when we say "can we have regexp in the IDE/VCL", because two different people asking for this may have two very different ideas as to <a href="http://www.regular-expressions.info/refflavors.html" rel="nofollow noreferrer">which regexp they want to see supported</a>.

So whilst it might nice to have a form of regexp support "built-in" you have to be aware that this will lead to problems when people start exchanging regexp recipes (with other people not using Delphi) and can't figure out why one person's valid regexp is not a valid regexp in Delphi.

So then it will be "regexp is broken in Delphi" or "why can't we have XYZ regexp support as well as the ABC flavour support?"

So at the moment I'd say having the choice as to which regexp is right for you is in some ways an advantage, assuming you can find a component/library for Delphi which supports that flavour. :)

<a href="http://www.regular-expressions.info/delphi.html" rel="nofollow noreferrer">The regular-expressions.info site also has a page specifically about Delphi support for regexp</a>.

RegEx is another thing you don't have in Delphi. Perhaps you try the <a href="http://www.regular-expressions.info/delphi.html" rel="nofollow noreferrer">PCRE-based Components for Delphi </a> (didn't test it myself).

I used TRegExp (mentioned by <a href="https://stackoverflow.com/users/160320/sdu">sdu</a>) a few years ago but now the <a href="http://regexpstudio.com/TRegExpr/TRegExpr.html" rel="nofollow noreferrer">link</a> seems to be dead. Curious...

blocks|key|1600330|text|如果你打算使用绝地代码库(JCL)，你仍然需要安装PCRE代码库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1600331|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If you are going to use Jedi Code Library(JCL), you will still need to to install a PCRE library.

Is there a library in the VCL for regular expressions?

If not can you recommend a good third party library.

Does Delphi VCL provide a regular expression library?
