  • How to remove the file extension in a zsh completion?

    - by meeselet
    I want to adjust zsh so that I can tab complete: myprog <tab> using all *.foo files in ~/somedir, but have it so that it displays them without the .foo extension. Is there any way to do this? This is what I have so far: #compdef myprog typeset -A opt_args local context state line local -a mydirs mydirs="(. ~/somedir)" _arguments -s -S \ "*:name:->foos" \ && return 0 case $state in (foos) _files -W ${mydirs} -g '*.foo(:r)' && return 0 ;; esac return 1 However, this displays double the output for every file (that is, each .foo file is listed with and without its extension). Is there any way around this?

  • How to loop an array with strings as indexes in PHP

    - by Axel Lambregts
    I had to make an array with as indexes A-Z (the alphabet). Each index had to have a value 0. So i made this array: $alfabet = array( 'A' => 0, 'B' => 0, 'C' => 0, 'D' => 0, 'E' => 0, 'F' => 0, 'G' => 0, 'H' => 0, 'I' => 0, 'J' => 0, 'K' => 0, 'L' => 0, 'M' => 0, 'N' => 0, 'O' => 0, 'P' => 0, 'Q' => 0, 'R' => 0, 'S' => 0, 'T' => 0, 'U' => 0, 'V' => 0, 'W' => 0, 'X' => 0, 'Y' => 0, 'Z' => 0 ); I also have got text from a file ($text = file_get_contents('tekst15.txt');) I have putted the chars in that file to an array: $textChars = str_split ($text); and sorted it from A-Z: sort($textChars); What i want is that (with a for loop) when he finds an A in the textChars array, the value of the other array with index A, goes up by one (so like: $alfabet[A]++; Can anyone help me with this loop? I have this atm: for($i = 0; $i <= count($textChars); $i++){ while($textChars[$i] == $alfabet[A]){ $alfabet[A]++; } } echo $alfabet[A]; Problem 1: i want to loop the alfabet array to, so now i only check for A but i want to check all indexes. Problem2: this now returns 7 for each alphabet index i try so its totally wrong :) I'm sorry about my english but thanks for your time.

  • How to best deal with photos passed to IFilter?

    - by sharptooth
    I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

  • Sending an array of complex objects in the get string in C# ASP.NET MVC

    - by Mr Snuffle
    Hi, I want to send an array of objects in the get request string. I know this isn't the optimal solution, but I really just want to get this up and running. If I have a class, something like this public class Data { public int a { get; set; } public int b { get; set; } } public class RequestViewData { public IList<Data> MyData { get; set; } } I thought I could bind the MVC route to a web request like this http://localhost:8080/Request?MyData[0].a=1&MyData[0].b=2&MyData[1].a=3&[MyData[1].b=4 But all this does is create an array of two data objects without populating the values 1,2, 3 or 4. Is there a way to bind complex objects arrays?

  • Package to compare LSA, TFIDF, Cosine metrics and Language Models

    - by gouwsmeister
    Hi, I'm looking for a package (any language, really) that I can use on a corpus of 50 documents to perform interdocument similarity testing in various metrics, like tfidf, okapi, language models, lsa, etc. I want as a result a document similarity matrix, i.e. doc1 is x% similar to doc2, etc... This is for research purposes, not for production. I specifically want the doc similarity matrix as I want to correlate this with human ratings. Thank you in advance!

  • Finding the Column Index for a Specific Value

    - by Btibert3
    Hi All, I am having a brain cramp. Below is a toy dataset: df <- data.frame( id = 1:6, v1 = c("a", "a", "c", NA, "g", "h"), v2 = c("z", "y", "a", NA, "a", "g"), stringsAsFactors=F) I have a specific value that I want to find across a set of defined columns and I want to identify the position it is located in. The fields I am searching are characters and the trick is that the value I am looking for might not exist. In addition, null strings are also present in the dataset. Assuming I knew how to do this, the variable position indicates the values I would like returned. > df id v1 v2 position 1 1 a z 1 2 2 a y 1 3 3 c a 2 4 4 <NA> <NA> 99 5 5 g a 2 6 6 h g 99 The general rule is that I want to find the position of value "a", and if it is not located or if v1 is missing, then I want 99 returned. In this instance, I am searching across v1 and v2, but in reality, I have 10 different variables. It is also worth noting that the value I am searching for can only exist once across the 10 variables. What is the best way to generate this recode? Many thanks in advance.

  • Is this a variation of the traveling salesman problem?

    - by Ville Koskinen
    I'm interested in a function of two word lists, which would return an order agnostic edit distance between them. That is, the arguments would be two lists of (let's say space delimited) words and return value would be the minimum sum of the edit (or Levenshtein) distances of the words in the lists. Distance between "cat rat bat" and "rat bat cat" would be 0. Distance between "cat rat bat" and "fat had bad" would be the same as distance between "rat bat cat" and "had fat bad", 4. In the case the number of words in the lists are not the same, the shorter list would be padded with 0-length words. My intuition (which hasn't been nurtured with computer science classes) does not find any other solution than to use brute force: |had|fat|bad| a solution ---+---+---+---+ +---+---+---+ cat| 2 | 1 | 2 | | | 1 | | ---+---+---+---+ +---+---+---+ rat| 2 | 1 | 2 | | 3 | | | ---+---+---+---+ +---+---+---+ bat| 2 | 1 | 1 | | | | 4 | ---+---+---+---+ +---+---+---+ Starting from the first row, pick a column and go to the next rows without ever revisiting a column you have already visited. Do this over and over again until you've tried all combinations. To me this sounds a bit like the traveling salesman problem. Is it, and how would you solve my particular problem?

  • WSSQL query for multiple computers at once

    - by Josh
    I can run normal searches just fine. Windows 7 won't let me add a network share to my local index, but I can query the remote index just fine. The problem is that I can't find a way to query two indexes at once. I was hoping that something like this would work: SELECT System.ItemName FROM compA.SystemIndex, compB.SystemIndex WHERE SCOPE='file://compA/pathA' OR SCOPE='file://compB/pathB' but it doesn't. For simple queries, I can query compA and compB separately and then merge the results myself, but I'm hoping for a better way. Anybody here have some experience with this?

  • Interview question: Check if one string is a rotation of other string.

    - by Webdev
    A friend of mine was asked the following question today at interview for the position of software developer. Given two string s1 and s2 how will you check if s1 is a rotated version of s2 ? Example: if s1 = "stackoverflow"; then the following are some of its rotated versions: "tackoverflows" "ackoverflowst" "overflowstack" where as "stackoverflwo" is not a rotated version. The answer he gave was: Take s2 and find the logest prefix that is a substring of s1, that will give you the point of rotation. Once you find that point, break s2 at that point to get s2a and s2b, then just check if concatenate(s2a,s2b) == s1 It looks like a good solution to me and my friend. But the interviewr though otherwise. He asked for a simpler solution. Please help me by telling how would you do this in Java/C/C++ ? Thanks in advance.

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

  • Storing the HTML output from a local PHP file into a string using file_get_contents

    - by bobo
    There is a header.php file and it contains some php codes that return HTML. I know I can use require, include to echo the results, but what I want to do is to store its processed output string into a variable. In a page, I used: $headerHTML=file_get_contents('header.php'); Then I got the PHP code output rather than the processed HTML output. I know adding http:// would help. But I prefer to keep using relative path, how can I tell the function to treat the php file correctly?

  • Insert string from database into an aspx and have databinding expressions within that text evaluated

    - by Christopher Edwards
    Well, as you can see I want something quick-and-dirty! How can I get a string from a db that has aspx databinding syntax in it and have the databinding expressions evaluated? So I have text such as this stored in the DB:- Hello <%=User.Name %> I haven't seen you since <%=User.LastVisit %> And I want it to be inserted here say:- ... <body> <form id="form1" runat="server"> <div> <asp:FormView ID="FormView1" DataSourceID="DataSource1" runat="server"> <ItemTemplate> <-- insert stuff here! --> ... But with the databinding expressions evaluated. I'd rather not build a full parsing, templating and evaluation engine...

But it is no working. Any ideas?

  • What is the safest way to pass strings around in C?

    - by chucknelson
    I have a program in C using Solaris with VERY ancient compatibility it seems. Many examples, even here on SO, don't work, as well as lots of code I've written on Mac OS X. So when using very strict C, what is the safest way to pass strings? I'm currently using char pointers all over the place, due to what I thought was simplicity. So I have functions that return char*, I'm passing char* to them, etc. I'm already seeing strange behavior, like a char* I passed having its value right when I enter a function, and then the value being mysteriously gone OR corrupted/overwritten after something simple like one printf() or an malloc to some other pointer. I was thinking maybe declaring a local char[] inside each function, using strcpy() immediately, and then eventually returning a pointer where char *returnval = strdup(localchar[]); This seems...sloppy. Can anyone point me in the right direction on a simple requirement?

  • Parsing HTTP - Bytes.length != String.length

    - by hotzen
    Hello, I consume HTTP via nio.SocketChannel, so I get chunks of data as Array[Byte]. I want to put these chunks into a parser and continue parsing after each chunk has been put. HTTP itself seems to use an ISO8859-Charset but the Payload/Body itself may be arbitrarily encoded: If the HTTP Content-Length specifies X bytes, the UTF8-decoded Body may have much less Characters (1 Character may be represented in UTF8 by 2 bytes, etc). So what is a good parsing strategy to honor an explicitly specified Content-Length and/or a Transfer-Encoding: Chunked which specifies a chunk-length to be honored. append each data-chunk to an mutable.ArrayBuffer[Byte], search for CRLF in the bytes, decode everything from 0 until CRLF to String and match with Regular-Expressions like StatusRegex, HeaderRegex, etc? decode each data-chunk with the proper charset (e.g. iso8859, utf8, etc) and add to StringBuilder. With this solution I am not able to honor any Content-Length or Chunk-Size, but.. do I have to care for it? any other solution... ?

  • Insert multiple records from a XML string differing on one parameter in SQL SERVER 2008

    - by Rohit
    Below in a query which inserts records to SimpleDictationProfileMapping table after reading it from a XML string. Now this query inserts a single record in which DictationCaptureProfileID is @dictationCaptureProfileId . Now i want to insert multiple rows in which @dictationCaptureProfileId is different and other 2 values are same. What i want to achieve by this is in case parent changes all child values should also change. INSERT INTO SimpleDictationProfileMapping ( DictationCaptureProfileID, DictationProfileMappingAttributeID, DictationProfileMappingAttributeValue ) SELECT @dictationCaptureProfileId, row.value('@attrId','varchar(max)'), row.value('@value', 'varchar(max)') FROM @simpleDictationCaptureProfileMappings.nodes('/simpleMappingAtribute/attribute') AS d ( row ) ; I want INSERT INTO SimpleDictationProfileMapping ( DictationCaptureProfileID OR (SELECT DictationCaptureProfileID FROM DictationCaptureProfile WHERE SystemDictationCaptureProfileID = @systemDictationCaptureProfileID), DictationProfileMappingAttributeID, DictationProfileMappingAttributeValue ) SELECT @dictationCaptureProfileId , row.value('@attrId','varchar(max)'), row.value('@value', 'varchar(max)') FROM @simpleDictationCaptureProfileMappings.nodes ('/simpleMappingAtribute/attribute') AS d ( row ) ; Please tell how to achieve this.

  • Having an @ inside of a string - PHP

    - by Msencenb
    So I know that you use a backslash to escape most things in php however the @ symbol is an operator that suppresses error messages. I'm trying to put an email string like this inside of an array "[email protected]", however php is throwing an error. How do you escape the @ sign? EDIT: Here is the code example that was throwing the error: $arr = array(3=> "[email protected]",4=> "[email protected]"); However replacing the double quotes with single quotes fixes the error as answered below.... why is that true?

  • Javascript: gradually adding to string in each iteration ?

    - by Kim Jong Woo
    I have a string like this that is split up: var tokens = "first>second>third>last".split(">"); What I would like in each iteration is for it to return Iteration 0: "last" Iteration 1: "third>last" Iteration 2: "second>third>last" Iteration 3: "first>second>third>last" I am thinking of using decrementing index for loop.... but is there a more efficient approach ? for (int w = tokens.length-1; w == 0; w--) { }
