nested

Source: [This] is some text with [some [blocks that are nested [in a [variety] of ways]]] Resultant text: [This] is some text with I don't think you can do a regex for this, from looking at the threads at stack overflow . Is there a simple way to to do this -> or must one reach for pyparsing (or other parsing library)? Taking the OP's example as normative (any block including further nested blocks must be removed), what about...: import itertools x = '''[This] is some text with [some [blocks that are nested [in a [variety] of ways]]] and some [which are not], and [any [with nesting] must go]

I have the following construct in my code: f :: Maybe A -> X f a = case a of Nothing -> x (Just b) -> case b of Nothing -> y (Just c) -> case c of Nothing -> z (Just d) -> d I'm not seeing an obvious way to simplify this instead of using nested maybe functions, which wouldn't make the whole thing look much better. Are there any clever - but still understandable - tricks that would help make this construct more "elegant"? UPDATED 2 Monad Either is for you import Data.Maybe (maybe) maybeE :: e -> Maybe a -> Either e a maybeE e = maybe (Left e) Right f :: Maybe (Maybe (Maybe d)) -> Either e d f a

With nested resource routes in Rails 3, such as the following: resources :magazines do resources :ads end helpers such as magazine_ad_path are defined, to which I have to pass both a magazine and the ad, which is inconvenient if I just have a reference to the ad: magazine_ad_path(@ad.magazine, @ad) Is there a nice way to set up an ad_path helper that takes the @ad and returns the appropriate address including the magazine ID? (This would also then allow the use of link_to @ad , redirect_to @ad , etc., which automatically call the ad_path helper corresponding to the model class.) Shallow

I have a Jar file named " OuterJar.jar " that contains another jar named " InnerJar.jar " this InnerJar contains 2 files named " Test1.class " & " Test2.class ".Now i want to extract these two files. I have tried some piece of code but it doesn't work. class NestedJarExtractFactory{ public void nestedJarExtractor(String path){ JarFile jarFile = new JarFile(path); Enumeration entries = jarFile.entries(); while (entries.hasMoreElements()) { JarEntry _entryName = (JarEntry) entries.nextElement(); if(temp_FileName.endsWith(".jar")){ JarInputStream innerJarFileInputStream=new JarInputStream(jarFile

I have a 3 level nested master pages and a content page. parent1 is the top parent, parent2 is parent of parent3 and parent3 is the parent of the content page. I get an error ' Cannot find ContentPlaceHolder xxx... ' where xxx is a ContentPlaceholder. It resides in parent2 and content page is trying to fill it. Can content pages only use their direct parent ContentPlaceHolders or can they also use any of the higher master pages? There is one way to do this but there is a slight problem with it under certain circumstances if you are relying on any default content from a placeholder. In your

I have a structure that roughly looks like this: List<ProductLine> -> ID Name ... List<LineOfBusiness> -> ID Name ... List<Watchlist> -> ID Name ReportCount A Watchlist can exist under multiple LoBs but the ReportCount will only be for the count of reports that exist under that LoB for that WatchList. I need them in the structure this way because the count of how many reports exist within a LoB for a given Watchlist is important elsewhere. What I need to do is get a list of the distinct WatchLists (grouped based on ID) and have the ReportCount be the SUM of that watchlist's ReportCount across

I have this code: var string = { nameString : "nameValue", nameString2 : "nameValue2", nameString3 : "nameValue3", datathing : 0, }; var data = { data : 1, dataNum2 : 2, dataNum3 : 3, dataNum4 : 4, }; var thing = { datathing1 : 10, datathing2 : 20, datathing3 : 30, datathing4 : 40, }; var object = { object1 : string, data1 : data, thing1 : thing, }; Why do neither of these means to access the data work: alert("testReference= " + object['object1']['string']['nameString']); alert("testReference= " + object.object1.string.nameString); I cannot understand it, even though similar examples found
