How do I efficiently reject Strings in an array if they (regex) match Strings in a second array in Ruby? -

-

I have two strings of strings, for example sentences and words if a word is found in a sentence eg Sentence = ~ / # {word} / I want to reject the sentence from the sentence array. It's easy to do this with double loop, but I'm thinking that there is a more efficient way to do this, perhaps with logical operators?

You can add all the words in a reggae, "|" character. 

  Sentence = ~ / word1 / word2 /

You can convert word array into an appropriate regex with array.join Are ("|").

If words are likely to include regex metacharacters, then include each word in non-capturing brackets. 

  Sentence = ~ / (?: Word 1). (?: Word2). .... /

Using one of the Rijx should be more efficient than looping through the array of words, since the regex will be compiled into a single state statement.

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
