  • Selectively parsing log files using Java

    - by GPX
    I have to parse a big bunch of log files, which are in the following format. SOME SQL STATEMENT/QUERY DB20000I The SQL command completed successfully. SOME OTHER SQL STATEMENT/QUERY DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. EDIT 1: The first 3 lines (including a blank line) indicate an SQL statement executed successfully, while the next three show the statement and the exception it caused. darioo's reply below, suggesting the use of grep instead of Java, works beautifully for a single line SQL statement. EDIT 2: However, the SQL statement/query might not be a single line, necessarily. Sometimes it is a big CREATE PROCEDURE...END PROCEDURE block. Can this problem be overcome using only Unix commands too? Now I need to parse through the entire log file and pick all occurrences of the pair of (SQL statement + error) and write them in a separate file. Please show me how to do this!

  • What should I know about Python to identify comments in different source files?

    - by Can't Tell
    I have a need to identify comments in different kinds of source files in a given directory. ( For example java,XML, JavaScript, bash). I have decided to do this using Python (as an attempt to learn Python). The questions I have are 1) What should I know about python to get this done? ( I have an idea that Regular Expressions will be useful but are there alternatives/other modules that will be useful? Libraries that I can use to get this done?) 2) Is Python a good choice for such a task? Will some other language make this easier to accomplish?

  • Notepad++ replacement

    - by bah
    Hi, I've been using notepad++ for a while now, but i noticed it doesn't have code snippets (i found quicktext plugin, but it doesn't work anymore), so i'd like to switch editor and my requirements would be: Fast startup. Code snippets. Ability to use themes. File tree view (or plugin, which does that). What are you using? Thank you all for suggestions!

  • Gedit adds line at end of page

    - by Sam
    The answer to this must be somewhere but I'm not finding it -- can anyone help me understand why in Gedit, if I have a page of code there is no extra trailing blank line, but then when I do a file comparison for my svn commit it shows an extra line being added at the end of the file? I have a feeling that Gedit is automatically adding an ending line break. But why, I have no idea...

  • Using vim, how do you quickly refresh a web page you're working on?

    - by aLostMonkey
    I've been using VIM for a few weeks now while messing with various web languages and I'm really enjoying it. I find it cumbersome having to tab or click into my browser and refresh the page to see the effect of a code change. It's even more annoying as I'm using Virtual Box and I tend to be working from PDF files on the host system so I have limited window space. Do you gurus have any fancy ways of doing this? I was wondering if it's possible to split the VIM workspace and have links/lynx in a window of its own or something to that effect?

  • Are there any XML Editors with FTP and file-tree browsing combined?

    - by JW
    Are there any (free preferably) XML Editors combined with FTP and file-tree browsing Project wide find+Replace I.e A bit like what Dreamweaver MX is but with fancier XML capabilities /XSLT /XSD Perhaps even DW does this...im still on an older version. I'd like to keep a smooth flow between find-edit-view-upload any ideas? Background: I have converted most of the html files of my legacy site into XML (which match the directory structure of my 'public docs' folder). Part of a step towards turning it into completely dynamic data via MVC /Front Controller Pattern.

  • Detect what is selected (highlighted) or clicked within an element on a page?

    - by Fog Cook
    How would one go about detecting what has been selected on a page in a browser? Example: Click, hold, select 3 words and 1 image on a page, release. Sub-question: How to detect what letter someone clicked on? Without using: A span injector breaking everything up OR a WYSIWYG plugin I'm hoping this isn't just a type of browser interaction you can't detect. There could be many uses, but my goal is a simple 'live' page editor, or at least a way to know what someone is clicking on/selecting aside from just the id of an element.

  • how to do reverse fulltext search in MySQL?

    - by Shore
    By default it's like this: select * from main_table where match(col1,col2) against('search_item'); but what I want to fetch is the reverse, say,I've restored all the search_item(1000 records,for example), and I want to see which of them matches a specified row in main_table. Is that doable?

  • Create comma seperated values in perl

    - by Mike
    Let's say I have a list of elements @list=(1,2,3); #desired output 1,2,3 And I want to print them as comma seperated values. And most importantly, I do not want the last element to have a comma after it. What is the cleanest way to do this in Perl?

  • SQL Server 2005 FREETEXT() Perfomance Issue

    - by Zenon
    I have a query with about 6-7 joined tables and a FREETEXT() predicate on 6 columns of the base table in the where. Now, this query worked fine (in under 2 seconds) for the last year and practically remained unchanged (i tried old versions and the problem persists) So today, all of a sudden, the same query takes around 1-1.5 minutes. After checking the Execution Plan in SQL Server 2005, rebuilding the FULLTEXT Index of that table, reorganising the FULLTEXT index, creating the index from scratch, restarting the SQL Server Service, restarting the whole server I don't know what else to try. I temporarily switched the query to use LIKE instead until i figure this out (which takes about 6 seconds now). When I look at the query in the query performance analyser, when I compare the ´FREETEXT´query with the ´LIKE´ query, the former has 350 times as many reads (4921261 vs. 13943) and 20 times (38937 vs. 1938) the CPU usage of the latter. So it really is the ´FREETEXT´predicate that causes it to be so slow. Has anyone got any ideas on what the reason might be? Or further tests I could do?

  • Forcing a mixed ISO-8859-1 and UTF-8 multi-line string into UTF-8 in Perl

    - by knorv
    Consider the following problem: A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1. I don't know a priori which lines are in which encoding, so heuristics will be needed. I want to turn $junk into pure UTF-8 with proper re-encoding of the ISO-8859-1 lines. Also, in the event of errors in the processing I want to provide a "best effort result" rather than throwing an error. My current attempt looks like this: $junk = &force_utf8($junk); sub force_utf8 { my $input = shift; my $output = ''; foreach my $line (split(/\n/, $input)) { if (utf8::valid($line)) { utf8::decode($line); } $output .= "$line\n"; } return $output; } While this appears to work I'm certain this is not the optimal solution. How would you improve the force_utf8(...) sub?

  • Perl, search array

    - by Mike
    What is the smartest way of searching through an array of strings for a matching string in Perl? One caveat, I would like the search to be case-insensitive so "aAa" would be in ("aaa","bbb")

  • Generate regular expression to match strings from the list A, but not from list B

    - by Vlad
    I have two lists of strings ListA and ListB. I need to generate a regular expression that will match all strings in ListA and will not match any string in ListB. The strings could contain any combination of characters, numbers and punctuation. If a string appears on ListA it is guaranteed that it will not be in the ListB. If a string is not in either of these two lists I don't care what the result of the matching should be. The lists typically contain thousands of strings, and strings are fairly similar to each other. I know the trivial answer to this question, which is just generate a regular expression of the form (Str1)|(Str2)|(Str3) where StrN is the string from ListA. But I am looking for a more efficient way to do this. Ideal solution would be some sort of tool that will take two lists and generate a Java regular expression for this. Update 1: By "efficient", I mean to generate expression that is shorter than trivial solution. The ideal algorithm would generate the shorted possible expression. Here are some examples. ListA = { C10 , C15, C195 } ListB = { Bob, Billy } The ideal expression would be /^C1.+$/ Another example, note the third element of ListB ListA = { C10 , C15, C195 } ListB = { Bob, Billy, C25 } The ideal expression is /^C[^2]{1}.+$/ The last example ListA = { A , D ,E , F , H } ListB = { B , C , G , I } The ideal expression is the same as trivial solution which is /^(A|D|E|F|H)$/ Also, I am not looking for the ideal solution, anything better than trivial would help. I was thinking along the lines of generating the list of trivial solutions, and then try to merge the common substrings while watching that we don't wander into ListB territory. *Update 2: I am not particularly worried about the time it takes to generate the RegEx, anything under 10 minutes on the modern machine is acceptable

  • List of uninteresting words

    - by Hooked
    [Caveat] This is not directly a programing question, but it is something that comes up so often in language processing that I'm sure it's of some use to the community. Does anyone have a good list of uninteresting (English) words that have been tested by more then a casual look? This would include all prepositions, conjunctions, etc... words that may have semantic meaning, but are often frequent in every sentence, regardless of the subject. I've built my own lists from time to time for personal projects but they've been ad-hoc; I continuously add words that I forgotten as they come in.

  • Vim (Windows) - new help files do not work

    - by Jon
    I have downloaded several new plugins which come with a help file. None of them seem to work from within Vim. I have the Windows version of gVim and the install dir contains a folder called: vimfiles vim72 Both folder contain a plugin and doc folder. Where am I supposed to put the plugin? So when I use :help [helpfile], it says it cannot find it, but I can see it in the doc folder.

  • CSS resizable menu and content background images

    - by Hristo
    Hello, I need to have resizable menu and content background images for my site, so both of them get stretched whenever the menu entries are too many, or the contents go outside the borders of the content background. I need vertical stretching. Could you, please, give me a hint (an actual answer would work as well) or a link to a good example? Thank you very much in advance!

  • What's the simplest way to extract the last section of an IP address?

    - by Jon Cage
    I have an IP address which I want to grab the last chunk of as an integer. So from "192.168.1.150" I'd get 150. This is the code I'd concocted (I'm using C++/CLI), but somehow it feels rather clunky: String^ ipString = "192.168.1.150"; int lastDot = ipString->LastIndexOf('.'); int lastSection = int::Parse(ipString->Substring(lastDot, ipString->Length-lastDot)); Is there a simpler way of doing this?
