例句

Commonly referred to as regexes, regular expressions are a feature of nearly all modern programming languages.

正則表達(dá)式是幾乎所有現(xiàn)代編程語(yǔ)言的共有特性之一，通常被簡(jiǎn)稱為regexes（regex的復(fù)數(shù)，RegularExpression的簡(jiǎn)稱）。

To help you catch runaway backtracking early, always test your regexes with long strings that contain partial matches.

Since JRuby aims to be a compatible implementation of Ruby 1. 8. x (or future versions), it's necessary to support the same Regexes.

However, this proved too complex with long regexes (it was difficult to decide how the group elements related to the regex).

但是，實(shí)踐證明對(duì)于很長(zhǎng)的正則表達(dá)式這樣太復(fù)雜了（很難確定group元素與正則表達(dá)式的關(guān)系）。

Using a concise shorthand, regexes describe the form of data and decompose it.

Regexes in Scala should contain no surprises if you've used them in other programming languages.

如果已經(jīng)在其它編程語(yǔ)言中使用正則表達(dá)式，那么Scala的應(yīng)該不會(huì)讓你感覺到驚訝。

Since the fields have a fixed length, the regexes are simple, taking the form . {5}, which means "any character, repeated five times. "

因?yàn)?/c>字段長(zhǎng)度是固定的，正則表達(dá)式非常簡(jiǎn)單，采用.{5}這樣的形式，其含義是“任意字符，重復(fù)5次”。

Regex可以記住與capture匹配的內(nèi)容。

Think about the kinds of strings that your regexes will nearly but not quite match, and include those in your tests.

針對(duì)你的正則表達(dá)式構(gòu)思一些近似但不能完全匹配的字符串，將他們應(yīng)用在你的測(cè)試中。
