  • Safest way to change variable names in a project

    - by kamziro
    So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

  • Accessing variable from ARGV

    - by snaken
    I'm writing a cPanel postwwwact script, if you're not familiar with the script its run after a new account is created. it relies on the user account variable being passed to the script which i then use for various things (creating databases etc). However, I can't seem to find the right way to access the variable i want. I'm not that good with shell scripts so i'd appreciate some advice. I had read somewhere that the value i wanted would be included in $ARGV{'user'} but this simply gives "root" as opposed to the value i need. I've tried looping through all the arguments (list of arguments here) like this: #!/bin/sh for var do touch /root/testvars/$var done and the value i want is in there, i'm just not sure how to accurately target it. There's info here on doing this with PHP or Perl but i have to do this as a shell script. EDIT Ideally i would like to be able to call the variable by something other than $1 or $2 etc as this would create issues if an argument is added or removed Any ideas?

  • Javascript redeclared global variable overrides old value

    - by Yousuf Haider
    I ran into an interesting issue the other day and was wondering if someone could shed light on why this is happening. Here is what I am doing (for the purposes of this example I have dumbed down the example somewhat): I am creating a globally scoped variable using the square bracket notation and assigning it a value. Later I declare a var with the same name as the one I just created above. Note I am not assigning a value. Since this is a redeclaration of the same variable the old value should not be overriden as described here: http://www.w3schools.com/js/js_variables.asp //create global variable with square bracket notation window['y'] = 'old'; //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows New instead of Old The problem is that the old value actually does get overriden and in the above eg. the alert shows 'new' instead of 'old'. Why ? I guess another way to state my question is how is the above code different in terms of semantics from the code below: //create global variable var y = 'old'; //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows Old

  • Uiimport does not save variable to base workspace

    - by Tim
    I tried using uiimport to load a file to the base workspace.....It worked first time....but after trying again after a while...I wasnt seeing the variable in the base work space. I used the default variable name which is given by 'uiimport". This was the command I used: uiimport(filename) And two variables where created by default..."data" and "textdata"(which is the header)....but now when i run it is no longer saved in the base workspace I do not want to assign a variable to the uiimport like so... K = uiimport(filename) assignin(base,'green',K) I do not want to do that because My dataset has a text header and the data itself, and doing this would assign both "textdata" and "data" to "green" variable How would I be able to get the dimensions of ONLY the "data" in green and how would I pass only "data"(which is in the green variable in the workspace.."rmbr"...the green variable holds both "data" and "textdata") to another function. I was able to do all this when the uiimport automatically saved the variables in the base workspace....but somehow now it doesn't. I would appreciate any help or tips on this matter

  • jquery - check length of input field?

    - by KnockKnockWhosThere
    The code below is intended to enable the submit button once the user clicks in the textarea field. It works, but I'm trying to also make it so that it's only enabled if there's at least one character in the field. I tried wrapping it in: if($(this).val().length > 1) { } But, that didn't seem to work... Any ideas? $("#fbss").focus(function(){ $(this).select(); if($(this).val()=="Default text") { $(this).val(""); $("input[id=fbss-submit]").removeClass(); $("input[id=fbss-submit]").attr('disabled',false); $("input[id= fbss-submit]").attr('class','.enableSubmit'); if($('.charsRemaining')) { $('.charsRemaining').remove(); $("textarea[id=fbss]").maxlength({ maxCharacters: 190, status: true, statusClass: 'charsRemaining', statusText: 'characters left', notificationClass: 'notification', showAlert: false, alertText: 'You have exceeded the maximum amount of characters', slider: false }); } });

  • variable in variable in batch and delayed expansion

    - by rezna
    Hi, I'm trying to use variable in variable in conjunction with delayed expansion but still no luck. SETLOCAL EnableDelayedExpansion SET ERROR_COMMAND=exit /B ^!ERRORLEVEL^! This is my last try. I want to setup an ERROR_COMMAND to be called when one of the steps in batch file crashes. The command is supposed to be: IF ERRORLEVEL 1 !ERROR_COMMAND! or IF ERRORLEVEL 1 %ERROR_COMMAND% The thing is, I'm not able to find out, how to SET properly the ERROR_COMMAND variable, so that ERRORLEVEL is not evaluated at the time of assignment, but at the time of evaluating the variable Of course I can copy&paste the code all over the batch file, but using the variable just seems a bit prettier... Anyone? Thanks, Milan

  • Xcode & passing command line arguments

    - by Brisco
    I just started working with C & Xcode and I've run into a little difficulty. All I want to do is read a file from the command line and see the output in the terminal. I think my problem lies with the path to the file that I want to read in. I'm using a Mac and the file is on my desktop, so the path should be Users/myName/Desktop/words.txt. Is this correct? This is my code: #import <Foundation/Foundation.h> int main (int argc, const char* argv[]){ if(argc == 1){ NSLog(@" you must pass at least one arguement"); return 1; } NSLog(@"russ"); FILE* wordFile = fopen(argv[1] , "r"); char word[100]; while (fgets(word,100,wordFile)) { NSLog(@" %s is %d chars long", word,strlen(word)); } fclose(wordFile); return 0; }//main

  • GCC, functions, and pointer arguments, warning behaviour

    - by James Morris
    I've recently updated to a testing distribution, which is now using GCC 4.4.3. Now I've set everything up, I've returned to coding and have built my project and I get one of these horrible messages: *** glibc detected *** ./boxyseq: free(): invalid pointer: 0x0000000001d873e8 *** I absolutely know what is wrong here, but was rather confused as to when I saw my C code where I call a function which frees a dynamically allocated data structure - I had passed it an incompatible pointer type - a pointer to a completely different data structure. warning: passing argument 1 of 'data_A_free' from incompatible pointer type note: expected 'struct data_A *' but argument is of type 'struct data_B *' I'm confused because I'm sure this would have been an error before and compilation would never have completed. Is this not just going to make life more difficult for C programmers? Can I change it back to an error without making a whole bunch of other warnings errors too? Or am I loosing the plot and it's always been a warning?

  • Invoke Java via Batch File with Filepath Arguments

    - by EricIdyll
    Hi there, I'm having an issue getting files loaded into an app called GCS, by dragging them onto the executable. GCS can be invoked on Windows with a bat file, which goes like this: @echo off start javaw -Xmx256M -jar "GURPS Character Sheet.app/Contents/Resources/Java/GCS.jar" %* If I hard code a filepath in place of the batch argument wildcard (with quotes), it works. If I run the debugger with a filepath argument it works. If I echo %, it gives me the correct filename with quotes around it. If I add quotes around % it still breaks. I have a disconnect here between DOS and Java, and I'm at a loss. Does anyone recognize this problem? Thanks in advance.

  • How to get the original variable name of variable passed to a function

    - by Acorn
    Is it possible to get the original variable name of a variable passed to a function? E.g. foobar = "foo" def func(var): print var.origname So that: func(foobar) Returns: >>foobar EDIT: All I was trying to do was make a function like: def log(soup): f = open(varname+'.html', 'w') print >>f, soup.prettify() f.close() .. and have the function generate the filename from the name of the variable passed to it. I suppose if it's not possible I'll just have to pass the variable and the variable's name as a string each time.

  • Small Python optional arguments question

    - by ooboo
    I have two functions: def f(a,b,c=g(b)): blabla def g(n): blabla c is an optional argument in function f. If the user does not specify its value, the program should compute g(b) and that would be the value of c. But the code does not compile - it says name 'b' is not defined. How to fix that? Someone suggested: def g(b): blabla def f(a,b,c=None): if c is None: c = g(b) blabla But this doesn't work, because maybe the user intended c to be None and then c will have another value.

  • Passing arguments to a C program

    - by Radhika
    Hi All, I was writing a C program where I use 6 variables a,b,c,d,e,f a,b,c are constant values which I should pass as an argument(command line) d,e,f are going to be size of arrays(which are a part of a structure) typedef struct { blah blah } ex; ex ex0[d]; I am very confused about how to pass all these as argument. Right now I have hard coded these values,which apparently I should not be doing.

  • Automatically open files given as command line arguments in Python

    - by mk
    I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

  • Use concat and maintain length of variable

    - by user1682055
    I'm trying to use concat on some variables. These variables have been declared as chars: declare v_order_date char(10); declare v_quantity char(11); declare v_plant char(100); I have a cursor where I am setting these as some outputs. To call the results, I am setting v_msg as set v_msg := concat( v_msg, '\n', v_order_date, v_quantity, v_plant); However, the result I am getting when I select v_msg is: 2012-01-222501008 Creeping Buttercup but I want to maintain the length of the declared variables in my select that looks like this 2012-01-22 250 1008 Creeping Buttercup Are there any suggestions? Thank you.

  • Parsing String into multiple variable length String (C#)

    - by Nassign
    I am currently trying to convert a VB6 program into C#. There was extensive use of string splitting into structure. For example, Dim Sample AS String Sample = "John Doe New York Test Comment" Public Type Struct1 Name As String * 15 Address As String * 10 Comment As String * 20 End Type Dim dataStruct As Struct1 Set dataStruct = Sample When the dataStruct is set, it will automatically split value into the 3 structure member. Is there a special function to do this in C#. The only way I know how to do this is thru Attributes/Annotation describing the length and start position of string. Any other suggestion?

  • Passing arguments to UILabel [ 2 ] *

    - by DesperateLearner
    I'm trying to call a method of the below (Scroll animation class) type from a viewcontroller class. -(void)CreateLabel:(CGRect )frame andLabel:(UILabel *[NUM_LABELS])label andview:(UIView *)view; I got some errors when I tried passing the argument. Any suggestion on how to call this? This is how I called that method ScrollAnimation *newAnimation = [[ScrollAnimation alloc] init]; [newAnimation CreateLabel:CGRectMake(0, 50, 300,30) andLabel:animateLabel[NUM_LABELS] andview:self.view]; I have the error /Volumes/Red Drive/CarTransition/CarTransition/ViewController.m:120:66: Implicit conversion of an Objective-C pointer to 'UILabel **' is disallowed with ARC /Volumes/Red Drive/CarTransition/CarTransition/ViewController.m:120:66: Incompatible pointer types sending 'UILabel *__strong' to parameter of type 'UILabel **'

  • drupal views block arguments

    - by slimcady
    I currently have a view (Drupal 6 using Views2) that properly aggregates a custom content type (videos) and filters them for a page display. When I create a block display, it previews the results in live preview just great, but when i go to the page expecting to see the block it doesn't appear. I'm fairly certain the argument I'm attempting to pass it fails because when I select "Display all results" for "Action to take if argument does not validate:" the block shows up on the page just fine. Any advice definitely appreciated.

  • Using xsl:variable in a xsl:foreach select statment

    - by Nefariousity
    I'm trying to iterate through an xml document using xsl:foreach but I need the select=" " to be dynamic so I'm using a variable as the source. Here's what I've tried: ... <xsl:template name="SetDataPath"> <xsl:param name="Type" /> <xsl:variable name="Path_1">/Rating/Path1/*</xsl:variable> <xsl:variable name="Path_2">/Rating/Path2/*</xsl:variable> <xsl:if test="$Type='1'"> <xsl:value-of select="$Path_1"/> </xsl:if> <xsl:if test="$Type='2'"> <xsl:value-of select="$Path_2"/> </xsl:if> <xsl:template> ... <!-- Set Data Path according to Type --> <xsl:variable name="DataPath"> <xsl:call-template name="SetDataPath"> <xsl:with-param name="Type" select="/Rating/Type" /> </xsl:call-template> </xsl:variable> ... <xsl:for-each select="$DataPath"> ... The foreach threw an error stating: "XslTransformException - To use a result tree fragment in a path expression, first convert it to a node-set using the msxsl:node-set() function." When I use the msxsl:node-set() function though, my results are blank. I'm aware that I'm setting $DataPath to a string, but shouldn't the node-set() function be creating a node set from it? Am I missing something? When I don't use a variable: <xsl:for-each select="/Rating/Path1/*"> I get the proper results. Here's the XML data file I'm using: <Rating> <Type>1</Type> <Path1> <sarah> <dob>1-3-86</dob> <user>Sarah</user> </sarah> <joe> <dob>11-12-85</dob> <user>Joe</user> </joe> </Path1> <Path2> <jeff> <dob>11-3-84</dob> <user>Jeff</user> </jeff> <shawn> <dob>3-5-81</dob> <user>Shawn</user> </shawn> </Path2> </Rating> My question is simple, how do you run a foreach on 2 different paths?

  • Sending / Forwarding variable arguments in ObjectiveC

    I know this is possible in other programming languages. Suppose we have the following arrangement: - (void) myMethod:(NSString*)variables, ... { // Handle business here. } - (void) anotherMethod:(NSString*)variables, ... { // We want to pass these variable arguments for handling [self myMethod:variables, ...]; // Do not pass GO } // Start the party: [self anotherMethod:@"arg1", @"arg2", @"arg3", @"arg4", nil]; What's the trick to get this working in ObjC?
