  • How could I make geometry advanced operations on bezier paths?

    - by yizzreel
    I have a library that draws regular bezier path figures (complex paths formed of a lot of bezier points), using midpoint approximation. I can draw them without problem, but I need to add support for advanced geometry operations: Nearest point of a curve, intersection, figure contains point, and more importantly, path combinations: difference, intersection, exclusive-or, union, ... Is there any good source to get all this? Thanks

  • Need Flex Regex Validation Expression for password that allows for only alphanumeric values and requ

    - by BlueDude
    Hi I'm trying to setup a RegexpValidator that only accepts a string of alphanumeric characters between 6-30 characters long and requires one number. I'm new to Regular Expressions and everything I've tried seems to keep returning an invalid ValidationRsultEvent. Here's a chunk of code: <mx:RegExpValidator id="regexValidator" source="{passwordInput}" property="text" triggerEvent="" valid="onPasswordValidate(event)" invalid="onPasswordValidate(event)" /> private function validateRegister():void { regexValidator.expression = "^(?=.*(\d|\W)).{6,30}$"; regexValidator.validate(); }

    - by aliocee
    I have sentences as shown in the below examples: $sen1 = "The quick brown fox jump KEYWORD over123 the3 lazy dog, fox is quick"; $sen2 = "The quick brown fox jump123 KEYWORD over the lazy dog, fox is quick"; i want to use the keyword 'KEYWORD' as my search string to extract the alphanumeric words before and after the search string using Perl regular expression. sample output: over123 jump123 NB: The word 'the3' is left out because i'm only searching for alphanumeric words exactly before or after the 'KEYWORD'.

  • Efficiency questions

    - by rayman
    Hi, I have to manage XML documents and Strings in my app. In terms of efficiency and memory usage, will a collection like ArrayList be much more expensive than String[]? Also, I could store the content as a regular String or XML. Is working with XML also more expensive? (When I say expensive, I am referring to the use of system resources.) If there are differences, are they significant? Thanks, Ray.

  • Need to add underscore to my regex

    - by TaMeR
    I suck at regular expression and just can't seem to figure this out. '/^[A-Za-z0-9](?:.[A-Za-z0-9]+)*$/' As it's right now it allows dots anytime after the first char and I like to add _ so that it allows both. Thanks

  • bash: assign grep regex results to array

    - by Ryan
    Hello everyone, I am trying to assign a regular expression result to an array inside of a bash script but I am unsure whether that's possible, or if I'm doing it entirely wrong. The below is what I want to happen, however I know my syntax is incorrect: indexes[4]=$(echo b5f1e7bfc2439c621353d1ce0629fb8b | grep -o '[a-f0-9]\{8\}') such that: index[1]=b5f1e7bf index[2]=c2439c62 index[3]=1353d1ce index[4]=0629fb8b Any links, or advice, would be wonderful :)

  • How to handle an array of pointers in Objective-C

    - by DougW
    I figured out the answer to this question, but I couldn't find the solution on here, so posting it for posterity. So, in Objective-C, how do you create an object out of a pointer in order to store it in objective-c collections (NSArray, NSDictionary, NSSet, etc) without reverting to regular C?

  • tabexpansion doesn't fall through if overridden

    - by guillermooo
    The tabexpansion function only works partially when I override it like so: function tabexpansion { param($line, $lastWord) if ($line -eq "hey ") { "you", "Joe" } } The custom completions work as expected, but now I only get the default autocomplete behavior for cmdlet names, not parameters. So New-TAB works fine, but New-Alias -TAB doesn't. How do I get the regular completions too after overriding tabexpansion?

  • Python: Recursively access dict via attributes as well as index access?

    - by Luke Stanley
    I'd like to be able to do something like this: from dotDict import dotdictify life = {'bigBang': {'stars': {'planets': [] } } } dotdictify(life) #this would be the regular way: life['bigBang']['stars']['planets'] = {'earth': {'singleCellLife': {} }} #But how can we make this work? life.bigBang.stars.planets.earth = {'singleCellLife': {} } #Also creating new child objects if none exist, using the following syntax life.bigBang.stars.planets.earth.multiCellLife = {'reptiles':{},'mammals':{}} My motivations are to improve the succinctness of the code, and if possible use similar syntax to Javascript for accessing JSON objects for efficient cross platform development.(I also use Py2JS and similar.)

  • How to synchronize HTML5 local/webStorage and server-side storage?

    - by thSoft
    I'm currently seeking solutions for transparently and automatically synchronizing and replicating across the client-side HTML5 localStorage or web storage and (maybe multiple) server-side storage(s) (the only requirement here that it should be simple and affordable to install on a regular hosting service). So do you have any experience with such libraries/technologies that offer data storage which automate the client-server storage synchronization and allow data to be available either offline or online or both? I think this is a fairly common scenario of web applications supporting offline mode...
