  • Postfix and right-associative operators in LR(0) parsers

    - by Ian
    Is it possible to construct an LR(0) parser that could parse a language with both prefix and postfix operators? For example, if I had a grammar with the + (addition) and ! (factorial) operators with the usual precedence then 1+3! should be 1 + 3! = 1 + 6 = 7, but surely if the parser were LR(0) then when it had 1+3 on the stack it would reduce rather than shift? Also, do right associative operators pose a problem? For example, 2^3^4 should be 2^(3^4) but again, when the parser have 2^3 on the stack how would it know to reduce or shift? If this isn't possible is there still a way to use an LR(0) parser, possibly by converting the input into Polish or Reverse Polish notation or adding brackets in the appropriate places? Would this be done before, during or after the lexing stage?

    hey, is it possible to add spacing between the cells? <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>test</title> <style> #wrap { display: table-row; /* there is no also cellspacing in CSS afaik :( */ } #wrap div { display: table-cell; /* margin: 40px; doesn't work for table-cell :( */ /* border: 30px solid transparent; works but it's as good as adding padding */ /* border: 30px solid white; works but the page background is invisible */ /* decoration: */ background-color: green; padding: 20px; } </style> </head> <body> <!-- don't touch the markup --> <div id="wrap"> <div>text1</div> <div>text2</div> </div> </body> </html>

  • PHP - complete url parser help

    - by Mark
    I have been trying to find an effective url parser, php's own does not include subdomain or extension. On php.net a number of users had contributed and made this: function parseUrl($url) { $r = "^(?:(?P<scheme>\w+)://)?"; $r .= "(?:(?P<login>\w+):(?P<pass>\w+)@)?"; $r .= "(?P<host>(?:(?P<subdomain>[-\w\.]+)\.)?" . "(?P<domain>[-\w]+\.(?P<extension>\w+)))"; $r .= "(?::(?P<port>\d+))?"; $r .= "(?P<path>[\w/]*/(?P<file>\w+(?:\.\w+)?)?)?"; $r .= "(?:\?(?P<arg>[\w=&]+))?"; $r .= "(?:#(?P<anchor>\w+))?"; $r = "!$r!"; // Delimiters preg_match ( $r, $url, $out ); return $out; } Unfortunately it fails on paths with a '-' and I can't for the life of me workout how to amend it to accept '-' in the path name. Thanks

  • XPathDocument behavior with DOCTYPE declaration

    - by gliderkite
    I use XPathDocument to parse an XML file, but if there's a doctype declaration, when I initializes a new instance of the XPathDocument class passing the path of the file, that contains the XML data, to its constructor, my application tries to connect to internet (probably to verify the correctness of the XML data) and remains blocked for a long period of time. This does not occur if I delete the doctype declaration from the XML file. XmlDocument.Load method has the same behavior. How can I fix this problem? Thanks.

  • Get the subdomain from a URL

    - by jb
    Getting the subdomain from a URL sounds easy at first. http://www.domain.example Scan for the first period then return whatever came after the "http://" ... Then you remember http://super.duper.domain.example Oh. So then you think, okay, find the last period, go back a word and get everything before! Then you remember http://super.duper.domain.co.uk And you're back to square one. Anyone have any great ideas besides storing a list of all TLDs? John

  • What's the easiest way to parse a string in C?

    - by Luca Matteis
    I have to parse this string in C: XFR 3 NS 207.46.106.118:1863 0 207.46.104.20:1863\r\n And be able to get the 207.46.106.118 part and 1863 part (the first ip address). I know I could go char by char and eventually find my way through it, but what's the easiest way to get this information, given that the IP address in the string could change to a different format (with less digits)?

  • How can I parse_url in PHP when there is a URL in a string variable?

    - by Eric O
    I am admittedly a PHP newbie, so I need some help. I am creating a self-designed affiliate program for my site and have the option for an affiliate to add a SubID to their link for tracking. Without having control over what is entered, I have been testing different scenarios and found a bug when a full URL is entered (i.e. "http://example.com"). In my PHP I can grab the variable from the string no problem. My problem comes from when I get the referring URL and parse it (since I need to parse the referring URL to get the host mane for other uses). Code below: $refURL = getenv("HTTP_REFERER"); $parseRefURL = parse_url($refURL); WORKS when incoming link is (for example): http://example.com/?ref=REFERRER'S-ID&sid=www.test.com ERROR when incoming link is (notice the addition of "http://" after "sid="): http://example.com/?ref=REFERRER'S-ID&sid=http://www.test.com Here is the warning message: Warning: parse_url(/?ref=REFERRER'S-ID&sid=http://www.test.com) [function.parse-url]: Unable to parse url in /home4/'directory'/public_html/hosterdoodle/header.php on line 28 Any ideas on how to keep the parse-url function from being thrown off when someone may decide to place a URL in a variable? (I actually tested this problem down to the point that it will throw the error with as little as ":/" in the variable)

  • Java, How to Instance HttpCookie from a String, any convenient ways?

    - by user435657
    Hi all, I have got a cookie string from HTTP response header like the following line: name=value; path=/; domain=.g.cn; expire=... I can parse the above line to key-value pairs, and, also it's easy to set the name and value to HttpCookie instance as this pair comes the first. But how to set the other pairs since I don't know which set-method corresponds to the name of the next name-value pair. Traverse all possible keys a cookie may contian and call the matched set-method, like below snippet? if (key.equalsIgnoreCase("path")) cookie.setPath(value); else if (key.equalsIgnoreCase("domain")) cookie.setDomain(value); That's foolish, any convenient ways? Thanks in advance.

  • what is the most elegant way in ruby to remove a parameter from url?

    - by dimus
    I would like to take out a parameter from url by it's name without knowing if it is the first, middle or last parameter and reassemble url again. I guess it is not that hard to write something on my own using CGI or URI, but I imagine such functionality exists already. Any suggestions? in: http://example.com/path?param1=one&param2=2&param3=something3 out: http://example.com/path?param2=2&param3=something3

  • In Jeditable, how do I make it so that when I click the div to edit, the text box content has initial value that is processed?

    - by TIMEX
    When the user clicks on the div, jeditable will make a text box. However, I want the initial text to be done with function stripTags(), instead of what's on the page. The reason is that I'm using some URL techniques to turn plain text links into URLs. When the user clicks on the div, jeditable is turning them into <a href=>..</a> Is there a "beforeSubmit" option in jeditable? http://www.appelsiini.net/projects/jeditable

  • Jquery UI dialog does not disappear

    - by iamrohitbanga
    I am using jquery-ui tabs and dialog functionality. Each tab has a button on the page which opens a dialog. This works for one of the tabs. However if I go the second tab, the button does not work there. When I come back to the first tab, the dialog does show up but the problem is I notice as I make switches back and forth to the first tab, it keeps on inserting new div's while the old div's have display:none set on them. I am doing this using JSP. This is how the reusable jsp looks like: <script> $(function() { var formData = null; $.ajax({ url : "addFormGenerator.html", success : function(data) { formData = data; $("#addFormDialog").html(data); $("#addFormDialog").dialog({ autoOpen : false, height : 300, width : 350, modal : true, buttons : { "Add" : function() { $(this).dialog("close"); }, Cancel : function() { $(this).dialog("close"); } }, close : function() { } }); } }); $("#addButton").button().click(function() { $("#addFormDialog").html(formData); $("#addFormDialog").dialog("open"); }); }); </script> <button id="addButton">Click here to Add New</button> <div id="addFormDialog" title="Add New"></div> This jsp fragment is included in other jsp pages as well. I was assuming as I switch between tabs the old button will be garbage collected. Can you help me understand the problem and fix it?

  • Intelligent search and generation of Java code, preferrably using Python?

    - by Ipsquiggle
    Basically, I do lots of one-off code generation, large-scale refactorings, etc. etc. in Java. My tool language of choice is Python, but I'll take whatever solutions you can offer. Here is a simplified illustration of what I would like, in a pseudocode Generating an implementation for an interface search within my project: for each Interface as iName: write class(name=iName+"Impl", implements=iName) search within the body of iName: for each Method as mName: write method(name=mName, body="// TODO implement this...") Basically, the tool I'm searching for would allow me to: parse files according to their Java structure ("search for interfaces") search for words contextualized by language elements and types ("variables of type SomeClass", "doStuff() method calls on SomeClass instances") to run searches with structural context ("within the body of the current result") easily replace or generate code (with helpers to generate, as above, or functions for replacing, "rename the interface to Foo", "insert the line Blah.Blah()", etc.) The point is, I don't want to spend a lot of time writing these things, as they are usually throwaway. But sometimes I need something just a little smarter than what grep offers. It wouldn't be too hard to write up a simplistic version of this, but if I'm going to use something like this at all, I'd expect it to be robust. Any suggestions of a tool/library that will help me accomplish this?

  • Javascript doesn't change document?

    - by egbokul
    Take a look at this example code, which doesn't work: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript"> <!-- function moveMe() { document.getElementById('moveme').top = 200; document.getElementById('moveme').style.backgroundcolor = 'green'; document.getElementById('writeme').innerHtml = 'abc'; alert('called!'); } // --> </script> <style type="text/css"> .moveable { position: absolute; top: 30px; left: 200px; width: 100px; height: 100px; background-color: yellow; } #writeme { background-color: red; color: white; } </style> </head> <body> <div id="moveme" class="moveable" onClick="moveMe()"> <p id="writeme">Hello!</p> </div> </body> </html> When I click on the text the alert is displayed, but nothing is changed in the document. The paragraph text is not overwritten, the div is not moved... tested it in FF and IE, also checked the DOM via Firebug: strange thing is that the new values are written to the nodes, but they are displayed in bold, and the old values are still there. WTF? I guess I'm missing something fundamental here.

  • How to generate random strings that match a given regexp?

    - by Pies
    Duplicate: Random string that matches a regexp No, it isn't. I'm looking for an easy and universal method, one that I could actually implement. That's far more difficult than randomly generating passwords. I want to create an application that takes a regular expression, and shows 10 randomly generated strings that match that expression. It's supposed to help people better understand their regexps, and to decide i.e. if they're secure enough for validation purposes. Does anyone know of an easy way to do that? One obvious solution would be to write (or steal) a regexp parser, but that seems really over my head. I repeat, I'm looking for an easy and universal way to do that. Edit: Brute force approach is out of the question. Assuming the random strings would just be [a-z0-9]{10} and 1 million iterations per second, it would take 65 years to iterate trough the space of all 10-char strings.

  • How to find multiple words on the same line in Notepad++

    - by Mike
    I have a 4MB log file from the Windows XP firewall which I'm trying to find lines that have both DROP and an IP and a port number. My regex-fu is weak and I'm assuming this is the reason I'm struggling. The words "DROP", "10.1.1.1" (for example) and "8801" need to be found on the same line and may be spread across the line and separated by one or more other words. Any help (or suggestions of another method to do this) are much appreciated.

  • Tools for Automated Source Code Editing

    - by Steve
    I'm working on a research project to automatically modify code to include advanced mathematical concepts (like adding random effects into a loop or encapsulating an existing function with a new function that adds in a more advanced physical model). My question to the community is: are there are any good tools for manipulating source code directly? I want to do things like Swap out functions Add variable declarations wherever they are required Determine if a function is multiplied by anything Determine what functions are called on a line of code See what parameters are passed to a function and replace them with alternatives Introduce new function calls on certain lines of code Wherever possible just leaving the rest of the code untouched and write out the results I never want to actually compile the code I only want to understand what symbols are used, replace and add in a syntactically correct way, and be able to declare variables at the right position. I've been using a minimal flex/bison approach with some success but I do not feel the it is robust. I hate to take on writing a full language parser just to add some new info to the end of a line or the top of a function. It seems like this is almost what is going to be required but it also seems like there should be some tools out there to do these types of manipulations already. The code to be changed is in a variety of languages, but I'm particularly interested in FORTRAN. Any thoughts?

  • Find XmlNode where attribute value is contained in string

    - by bflemi3
    I have an xml file... <?xml version="1.0" encoding="UTF-8"?> <items defaultNode="1"> <default contentPlaceholderName="pageContent" template="" genericContentItemName="" /> <item urlSearchPattern="connections-learning" contentPlaceholderName="pageContent" template="Connections Learning Content Page" genericContentItemName="" /> <item urlSearchPattern="online-high-school" contentPlaceholderName="pageContent" template="" genericContentItemName="" /> </items> I am trying to find the first node where the urlSearchPattern attribute is contained in the string urlSearchPattern. Where I'm having trouble is finding the nodes where the attribute is contained in the string value instead of the string value be contained in the attribute. Here's my attempt so far. This will find the firstOrDefault node where the string value is contained in the attribute (I need the opposite)... string urlSearchPattern = Request.QueryString["aspxerrorpath"]; MissingPageSettingsXmlDocument missingPageSettingsXmlDocument = new MissingPageSettingsXmlDocument(); XmlNode missingPageItem = missingPageSettingsXmlDocument.SelectNodes(ITEM_XML_PATH).Cast<XmlNode>().Where(item => item.Attributes["urlSearchPattern"].ToString().ToLower().Contains(urlSearchPattern)).FirstOrDefault();

  • Regex to match a Java method signature

    - by nitesh
    I am having this particular requirement where a method has to be identified by different regular expressions for different components. For example, there need to be a regex for return parameter, one for method name, one for argument type and one for argument name. I was able to come up with an expression till this step as follows - ([^,]+) ([^,]+)\((([^,]+) ([^,]+))\) It works well for a method signature like - ReturnType foo(Arg parameter) The regular expression identifies ReturnType, foo, Arg and parameter separately. Now the problem is that a method can have no/one/multiple arguments separated by commas. I am not able to get a repeating expression for this. Help will be appreciated.
