delimiter

问题 I have a string and I would like to split that string by delimiter at a certain position. For example, my String is F/P/O and the result I am looking for is: Therefore, I would like to separate the string by the furthest delimiter. Note: some of my strings are F/O also for which my SQL below works fine and returns desired result. The SQL I wrote is as follows: SELECT Substr('F/P/O', 1, Instr('F/P/O', '/') - 1) part1, Substr('F/P/O', Instr('F/P/O', '/') + 1) part2 FROM dual and the result is:

问题 I want to iterate through a list of files without caring about what characters the filenames might contain, so I use a list delimited by null characters. The code will explain things better. # Set IFS to the null character to hopefully change the for..in # delimiter from the space character (sadly does not appear to work). IFS=$'\0' # Get null delimited list of files filelist="`find /some/path -type f -print0`" # Iterate through list of files for file in $filelist ; do # Arbitrary operations

问题 System.out.println( Arrays.deepToString( "abc<def>ghi".split("(?:<)|(?:>)") ) ); This prints [abc, def, ghi] , as if I had split on "<|>" . I want it to print [abc, <def>, ghi] . Is there a way to work some regex magic to accomplish what I want here? Perhaps a simpler example: System.out.println( Arrays.deepToString( "Hello! Oh my!! Good bye!!".split("(?:!+)") ) ); This prints [Hello, Oh my, Good bye] . I want it to print [Hello!, Oh my!!, Good bye!!] . `. 回答1: You need to take a look at zero

问题 In a config file, I have a key to which I wish to assign a URL. The problem is that YAML interprets : and - characters as either creating mappings or lists, so it has a problem with the line url: http://www.example-site.com/ (both because of the colon following http and the hyphen in the middle) Is there an explicit way to escape ':' and '-' ? Or would it work to just put the whole thing in single quotes and call it a day? 回答1: Quotes: "url: http://www.example-site.com/" To clarify, I meant

问题 sc = new Scanner(new File(dataFile)); sc.useDelimiter(",|\r\n"); I don't understand how delimiter works, can someone explain this in layman terms? 回答1: The scanner can also use delimiters other than whitespace. Easy example from Scanner API: String input = "1 fish 2 fish red fish blue fish"; // \\s* means 0 or more repetitions of any whitespace character // fish is the pattern to find Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*"); System.out.println(s.nextInt()); // prints: 1

问题 I am using the following sql: DELIMITER $$ DROP PROCEDURE IF EXISTS `get_auto_increment_settings`$$ CREATE PROCEDURE `get_auto_increment_settings`() BEGIN select @@global.auto_increment_offset as 'offset', @@global.auto_increment_increment as 'increment' ; END $$ DELIMITER ; I stored this in db_auto_increment_settings_procedure.sql and when I am trying to execute this from ant, I am facing the following error: [sql] Executing resource: /mysql/install/db_auto_increment_settings_procedure.sql

问题 I want to split my sentence using whitespace as my delimiter except for escaped whitespaces. Using boost::split and regex, how can I split it? If not possible, how else? Example: std::string sentence = "My dog Fluffy\\ Cake likes to jump"; Result: My dog Fluffy\ Cake likes to jump 回答1: Three implementations: With Boost Spirit With Boost Regex Handwritten parser With Boost Spirit Here's how I'd do this with Boost Spirit. This might seem overkill, but experience teaches me that once you're
