问题 A popular text editor has the following "find in files" feature that opens in a dialog box: Look For: __searchtext__ File Filter: *.txt; *.htm Start From: c:/docs/2009 Report: [ ] Filenames [ ]FileCount only Method: [ ] Regex [ ]Plain Text In fact, several popular text editors have this. I would like to do the same thing but using a python or ruby class instead of a text editor. That way, this same kind of brain-dead simple operation can be run from a script on any platform that supports ruby

问题 I have a list: l = [['en', 60, 'command'],['sq', 34, 'komand']] I want to search for komand or sq and get l[1] returned. Can I somehow define my own matching function for list searches? 回答1: An expression like: next(subl for subl in l if 'sq' in subl) will give you exactly the sublist you're searching for (or raise StopIteration if there is no such sublist; if the latter behavior is not what you want, pass next a second argument [[e.g, [] or None , depending on what exactly you want!]] to

问题 I need to do a boolean function which returns true if a word is in the text of a HTML page and false if it's not. I know that it's easy to do analysing all the page tree until finding the word with the lxml library but I find inefficient to iterate through all the html blocks and find if the word is there. Any suggestions for a faster algorithm (I need to do this search so many times)? 回答1: As long as you're not worried about accidentally finding the word in an element attribute or something

问题 I'm creating a used cars website (written in PHP), and I'm stuck on sending advanced search options from form. I have more than 30 of them and I wonder if it's possible, and how, to send them in one variable (for example &options=1,2,3,5,6,10 or some other way..). Also I've heard that this is possible with "bitwise" but I don't have a clue how to do that. Or if someone have a better idea, please let me know. Thanks. 回答1: You can send them in an array. <form method="post"> <input type=

问题 I'm working on an application, an user can search for files or folders either on the local computer or on the network. I am using DirectoryInfo.GetDirecotories(). (a) But I also want to add the functionality that windows 7 uses for searching, I believe that uses indexing. I also saw "Windows Searching Service" on msdn, but I'm not sure which way is best, querying the indexed catalog or using the search service, any suggestions ? (b) I was wondering if any one can give me a small example in C#

问题 I have defined dynamic field in ApacheSolr: I use it to store products features like: color_feature, diameter_feature, material_feature and so on. Number of those fields are not constant becouse products are changing.

问题 Right now, all I know to use is: find / -name string.* that is case sensitive and it won't find files named: 1string.x STRing.x string1.x How can I search so that all the above would be returned in the search to a case-insensitive matching? 回答1: Or you could use find / | grep -i string 回答2: Use the -iname option instead of -name . 回答3: This works as well, if you want to avoid the single quotes: find . -iname \*string\* 回答4: Use -iname in find for case insensitive file name matches. 回答5: If
