  • RegEx - Match optional groups

    - by Maurizio
    I know RE is not the best way to scrape HTMLs, but this is it... I have some something like: <td> Writing: <a href="creator.php?c=CCh">Carlo Chendi</a> Art: <a href="creator.php?c=LBo">Luciano Bottaro</a> </td> And I need to match the Writing and Art parts. But it is not said they're there and there could be other parts like Ink and Pencils... How do i do this ? I need to use pure Regex, no additional Python libs... Thanks !

  • Nested Groups in Regex

    - by cryptic-star
    I'm constructing a regex that is looking for dates. I would like to return the date found and the sentence it was found in. In the code below, the strings on either side of date_string should check for the conditions of a sentence. For your sake, I've omitted the regex for date_string - sufficed to say, it works for picking out dates. While the inside of date_string isn't important, it is grouped as one entire regex. "((?:[^.|?|!]*)"+date_string+"(?:[^.|?|!]*[.|?|!]\s*))" The problem is that date_string is only matching the last number of any given date, presumably because the regex in front of date_string is matching too far and overrunning the date regex. For example, if I say "Independence Day is July 4.", I will get the sentence and 4, even though it should match 'July 4'. In case you're wondering, my regex inside date_string are ordered in such a way that 'July 4' should match first. Is there any way to do this all in one regex? Or do I need to split it up somehow (i.e. split up all text into sentences, and then check each sentence)?

  • Does Team Foundation support cross-app workitem groups?

    - by drachenstern
    We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?

  • GAE Entity Groups/Transaction

    - by bach
    Hi, Say you have a Client Buying Card object and a product object. When the client chooses the buy opition you create the object and then add a product. It should be transactional but it's not on the same entity group as the product and the card already been persisted, isn't it? Is there any way to overcome this simple scenario safely and easily? here's a code sample: Transaction tx = pm.currentTransaction(); tx.begin(); Product prod = pm.getObjectById(Product.class, "TV"); prod.setReserved(true); pm.makePersistent(prod); Card card = pm.getObjectById(Card.class, "user123"); /// <--- will thorw an exception as card and prod aren't on the same entity group card.setProd(prod); pm.makePersistent(card); try { tx.commit(); break; }

  • jQuery Validation plugin: checkbox groups and error message issues

    - by boomturn
    I've put together a form using the jQuery Validation plugin, and all inputs are fine with working validation and error messages – except for checkboxes. I have two checkbox problems. The first is that the Validation plugin API doesn't seem to handle checkboxes in grouped contexts (I'm using fieldsets for grouping). Found several approaches to the issue here, including reference to a post by Rebecca Murphey for a more general case using a custom method and class. Adapting that to this situation: jQuery.validator.addMethod('required_group', function(val, el) { var fieldParent = $(el).closest('fieldset'); return fieldParent.find('.required_group:checked').length; }); jQuery.validator.addClassRules('required_group', { 'required_group': true }); jQuery.validator.messages.required_group = 'Please check at least one box.'; This sort of works, but produces error messages on every checkbox, and only removes them as each box is clicked. This is not an acceptable situation for the user, who can only get rid of them by clicking false positives. Ideally, I guess what's needed is something to prevent or eliminate extra messages before they are displayed and use errorPlacement to display a single error message in the parent fieldset, that would then be removed with a click on any checkbox. Less ideally, maybe they would all display but an event handler could turn off the full set of redundant messages with a click, which is what this approach offered by tvanfosson appears to do. (Another customized approach here, but I couldn't get it to work.) I guess I should also note this form requires the checkboxes to have different names. My second problem is that one of the fieldsets with checkboxes in the form also contains a nested fieldset of checkboxes under one of the outer checkboxes. So in addition to the first-level one-box-checked requirement, if the particular checkbox containing the second-level checkboxes is checked, then at least one of the second-level boxes must be checked. Not sure about the right approach; I'm guessing what needs to happen (following the above scheme) is that the trigger checkbox would use toggleClass to add/remove 'required_group' class to all the checkboxes in the subfield, which would then (hopefully) behave the same as the parent field: $("#triggerCheckbox").click(function () { $(this).find(":checkbox").toggleClass("required_group"); }); Any suggestions or ideas welcome. I'm well beyond my limited jQuery skills on this one and would be happy to hear that I missed simple, elegant and/or obvious ways to do this!

  • Framework for adding users/groups/permissions functionality to an application (possibly integrating

    - by vfilby
    I am looking to see if there is a good library or framework that I can use to simplify adding user/group/permission management to a .Net application (4.0 VS2010). If the framework can work on it's own or integrate with Active Directory that would be a huge bonus. So far I have found Visual Guard, if you have any experience using Visual Guard to provide user/group/permission functionality I definitely want to hear your feedback on how you liked working with it, pitfalls and benefits

  • Calculating a Sample Covariance Matrix for Groups with plyr

    - by John A. Ramey
    I'm going to use the sample code from http://gettinggeneticsdone.blogspot.com/2009/11/split-apply-and-combine-in-r-using-plyr.html for this example. So, first, let's copy their example data: mydata=data.frame(X1=rnorm(30), X2=rnorm(30,5,2), SNP1=c(rep("AA",10), rep("Aa",10), rep("aa",10)), SNP2=c(rep("BB",10), rep("Bb",10), rep("bb",10))) I am going to ignore SNP2 in this example and just pretend the values in SNP1 denote group membership. So then, I may want some summary statistics about each group in SNP1: "AA", "Aa", "aa". Then if I want to calculate the means for each variable, it makes sense (modifying their code slightly) to use: > ddply(mydata, c("SNP1"), function(df) data.frame(meanX1=mean(df$X1), meanX2=mean(df$X2))) SNP1 meanX1 meanX2 1 aa 0.05178028 4.812302 2 Aa 0.30586206 4.820739 3 AA -0.26862500 4.856006 But what if I want the sample covariance matrix for each group? Ideally, I would like a 3D array, where the I have the covariance matrix for each group, and the third dimension denotes the corresponding group. I tried a modified version of the previous code and got the following results that have convinced me that I'm doing something wrong. > daply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) , , = 1 SNP1 1 2 aa 1.4961210 -0.9496134 Aa 0.8833190 -0.1640711 AA 0.9942357 -0.9955837 , , = 2 SNP1 1 2 aa -0.9496134 2.881515 Aa -0.1640711 2.466105 AA -0.9955837 4.938320 I was thinking that the dim() of the 3rd dimension would be 3, but instead, it is 2. Really this is a sliced up version of the covariance matrix for each group. If we manually compute the sample covariance matrix for aa, we get: [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 Using plyr, the following gives me what I want in list() form: > dlply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) $aa [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 $Aa [,1] [,2] [1,] 0.8833190 -0.1640711 [2,] -0.1640711 2.4661046 $AA [,1] [,2] [1,] 0.9942357 -0.9955837 [2,] -0.9955837 4.9383196 attr(,"split_type") [1] "data.frame" attr(,"split_labels") SNP1 1 aa 2 Aa 3 AA But like I said earlier, I would really like this in a 3D array. Any thoughts on where I went wrong with daply() or suggestions? Of course, I could typecast the list from dlply() to a 3D array, but I'd rather not do this because I will be repeating this process many times in a simulation. As a side note, I found one method (http://www.mail-archive.com/[email protected]/msg86328.html) that provides the sample covariance matrix for each group, but the outputted object is bloated. Thanks in advance.

  • JSF/Seam - call one component method for many radio groups

    - by purecharger
    I've got the following jsf page: <h:form> <ui:repeat value="#{list.categories}" var="cat"> <h:selectOneRadio id="sel1Rad" value="#{list.choose}" layout="pageDirection"> <f:selectItems value="#{list.names}"/> </h:selectOneRadio> </ui:repeat> <h:commandButton id="submit" action="#{list.submit}" value="Submit"/> </h:form> And a component named list. The variable cat is injected to the component, used by the method list.getNames(). What I am trying to have happen is to have list.choose() be called for each radio group. I'm not sure if this is possible with Seam. Going by the booking example distributed with Seam, there is a distinct separate method for each selectOneRadio or selectOneMenu group. Since I have an unknown number of categories, I can't / don't want to define a method for each possible choice. When I submit the form, all my choices are sent in the POST, I just don't know the correct way to tell Seam how to dispatch them to my component. Any help is appreciated!

  • Using Regex groups in bash

    - by AlexeyMK
    Greetings, I've got a directory with a list of pdfs in it: file1.pdf, file2.pdf, morestuff.pdf ... etc. I want to convert these pdfs to pngs, ie file1.png, file2.png, morestuff.png ... etc. The basic command is, convert from to, But I'm having trouble getting convert to rename to the same file name. The obvious 'I wish it worked this way' is convert *.pdf *.png But clearly that doesn't work. My thought process is that I should utilize regular expression grouping here, to say somethink like convert (*).pdf %1.png but that clearly isn't the right syntax. I'm wondering what the correct syntax is, and whether there's a better approach (that doesn't require jumping into perl or python) that I'm ignoring. Thanks!

  • User Management: Managing users in user-defined "groups", database schema and logistics

    - by Kevin Brown
    I'm a noob, development wise and logistically-wise. I'm developing a site that lets people take a test... My client wants the ability for a user with the roll/privledge "admin" (a step below a super-admin) to be allowed to create users and only see/edit the users that they create... The users created in that "category" or group need some information that their superior provides. For example, I log in as a "manager", I have the ability to invite people to take the test, and manage those people. Before adding those people, I will have filled out a short survey about myself... Right now, the users that are invited will be asked some of the same questions as the manager. I'd like to cut down the redundancy by using the information put into the database by the manager and apply it to the invited users. How do I set up my database to work with this criterion? I'm a little confused about how to do this! Let me know if I can add more details... (This is a mysql and php app)

  • Python regular expressions assigning to named groups

    - by None
    When you use variables (is that the correct word?) in python regular expressions like this: "blah (?P\w+)" ("value" would be the variable), how could you make the variable's value be the text after "blah " to the end of the line or to a certain character not paying any attention to the actual content of the variable. For example, this is pseudo-code for what I want: >>> import re >>> p = re.compile("say (?P<value>continue_until_text_after_assignment_is_recognized) endsay") >>> m = p.match("say Hello hi yo endsay") >>> m.group('value') 'Hello hi yo' Note: The title is probably not understandable. That is because I didn't know how to say it. Sorry if I caused any confusion.

  • Manage groups of build configurations in Hudson

    - by Lóránt Pintér
    I'm using Hudson to build my application. I have several branches that come and go. Whenever there's a new branch, I have to set up the following builds for it: a continuous build that runs after every change in SVN a nightly build a nightly site generation (I'm using Maven under the hood) and a weekly integration build for some branches currently this means I need to copy four template configurations and set them up with the branch URL. I don't like this for two reasons: It's redundant, so modifying something is error-prone and takes a lot of time. I need four full checkouts of the product per branch on every build slave, plus four separate private Maven repository, not to mention the built artifacts. This is a lot of space wasted. What I'd like instead is to have one workspace and one configuration for allthese builds. Is this possible with Hudson?

  • ssrs column groups disable multiple columns

    - by DKS
    I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

    Hi there, I have the following requirement I have 3 domains namely: class Product { String productName static constraints = { productName(unique:true,blank:false) } class SubType { String subTypeName static constraints = { subTypeName(unique:true,blank:false) } String toString() { "${subTypeName}" } } class CLType { String TypeName static belongsTo = Car static hasMany = [car:Cars] static constraints = { } String toString() { "${TypeName}" } class CLines implements Serializable { Dealer dealer CLType clType SubType subType Product product static constraints = { dealer(nullable:false,blank:false,unique:['subType','product','clType']) clType(blank:false,nullable:false) subType(nullable:true) product(nullable:true) } } I want to achieve this combination: A user can assign dealer a CLType. But cannot have duplicates. As an example consider this scenario Please let me know what to mention in my unqiue constraint to make this possible? Thanks, Much Appreciated.

  • Separate groups of objects based on their properties

    - by Bevin
    I want to separate an array of my custom object into several arrays, based on the values of their two properties. The struct looks like this: struct MyStruct { public string Person { get; set; } public string Command { get; set; } } Now, if I have an array with a few objects: {Person1, cmd1} {Person1, cmd3} {Person2, cmd3} {Person3, cmd2} {Person2, cmd4} I want to be able to place them into one array for each person, that lists all of the commands for that person: {Person1: cmd1, cmd3} {Person2: cmd3, cmd4} {Person3: cmd2} I hope I've made it clear with my descriptions. I would assume that there is an elegant way to do this with LINQ, but I have no idea where to start.

  • Java replace all capturing groups

    - by Don
    Hi, If I have a regex with a capturing group, e.g. foo(g.*f). If I match this against a string and want to replace the first capturing group in all matches with baz so that foog___f blah foog________f is converted to: foobaz blah foobaz There doesn't appear to be any easy way to do this using the standard libraries, because the Matcher.replaceAll() method will only replace all matches of the entire pattern, am I missing something? Obviously I can just iterate through the matches, store the start and end index of each capturing group, then go back and replace them, but is there an easier way? Thanks, Don

  • Create unique identifier for different row-groups

    - by Max van der Heijden
    I want to number certain combinations of row in a dataframe (which is ordered on ID and on Time) tc <- textConnection(' id time end_yn number abc 10 0 1 abc 11 0 2 abc 12 1 3 abc 13 0 1 def 10 0 1 def 15 1 2 def 16 0 1 def 17 0 2 def 18 1 3 ') test <- read.table(tc, header=TRUE) The goal is to create a new column ("journey_nr") that give a unique number to each row based on the journey it belongs to. Journeys are defined as a sequence of rows per id up until to end_yn == 1, also if end_ynnever becomes 1, the journey should also be numbered (see the expected outcome example). It is only possible to have end_yn == 0 journeys at the end of a collection of rows for an ID (as shown at row 4 for id 3). So either no end_yn == 1 has occured for that ID or that happened before the end_yn == 0-journey (see id == abc in the example). I know how to number using the data.table package, but I do not know which columns to combine in order to get the expected outcome. I've searched the data.table-tag on SO, but could not find a similar problem. Expected outcome: id time end_yn number journey abc 10 0 1 1 abc 11 0 2 1 abc 12 1 3 1 abc 13 0 1 2 def 10 0 1 3 def 15 1 2 3 def 16 0 1 4 def 17 0 2 4 def 18 1 3 4

Assume its random or taken from user input (I put static vals here to keep it simple). Thanks for any help.
