  • Git: Merge in only one commit

    - by Ivan
    Usually, I work with branches in Git, but I don't like to see hundreds of branches in my working tree (Git history). I'm wondering if there is a method in Git to "join" all commits in a branch in only one commit (ideally with a clear commit message). Something like this: git checkout -b branch <some work> git commit -a -m "commit 1" <some work> git commit -a -m "commit 2" <some work> git commit -a -m "commit 3" git checkout master git SUPER-JOIN branch -m "super commit" After this, only "super commit" will exist in the git log.

  • Recommendations with hierarchical data on non-relational databases?

    - by Luki
    I'm developing an web application that uses a non-relational database as a backend (django-nonrel + AppEngine). I need to store some hierarchical data (projects/subproject_1/subproject_N/tasks), and I'm wondering which pattern should I use. For now I thought of: Adjacency List (store the item's parent id) Nested sets (store left and right values for the item) In my case, the depth of nesting for a normal user will not exceed 4-5 levels. Also, on the UI, I would like to have a pagination for the items on the first level, to avoid to load too many items at the first page load. From what I understand so far, nested sets are great when the hierarchy is used more for displaying. Adjacency lists are great when editing on the tree is done often. In my case I guess I need the displaying more than the editing (when using nested sets, even if the display would work great, the above pagination could complicate things on editing). Do you have any thoughts and advice, based on your experience with the non-relational databases?

  • basic json > struct question

    - by danwoods
    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

  • jQuery: How to hide all HTML elements which have a value greater than a certain value for a given ta

    - by Ankur
    I display elements in a hierarchy, clicking one displays the next set of elements in the hirearchy. Each element has a tag called "level" which has some value which is 1-.... (whatever the number of levels is for that branch of the tree). When an element is clicked I want the next elements to be displayed, but if an element is clicked and it's subelements have already been displayed I want to hide all subelements. More formally: when an element with level = x is clicked if no elements with level x are displayed then display all elements such that level = x+1 but if some elements with level x are displayed then hide all elements where level x How would I create a jQuery selector that captures this.

  • Loading xml with Jquery - why doesn't this work

    - by es11
    I have regular javascript code and am trying to utilize JQuery just to load and parse an xml file. I have the following: function loadXml() { $(function() { $.ajax({ type: "GET", url: "my_file.xml", dataType: "xml", success: parseXml }); }); } function parseXml() { alert("Parsing..."); } When calling loadXml I cannot get the callback success function to execute. I am running this all locally and my_file.xml resides in the same directory as this javascript. Any ideas?

  • Customizing Log4j to filter PatternLayout

    - by JavaScriptDude
    Greetings, I have just starting migrating to WLS 10.x and have noticed that the thread name [%t] for WL is quite verbose and more informative than I need for my deployment needs. Ultimately, I only care about the thread ID but WL gives me this:    [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' ~ Does anybody know if there is a way in log4j to write a custom filter that will allow me to override PatternLayout so I can parse the WLS Thread Name to just output the thread ID which in this case above is 0. I'd rather extend then customize as it makes upgrading libraries so much easier. Thanks :) - JsD

  • How to access a website's url programmatically from within the page

    - by Jeff
    For work, I am working on a site that has a feature that lets users make custom instances of the site depending on who they want to show it to. So if they want to show their potential employer a little bit about themselves, they can send them a custom url, that has a uid on the end of it that tells the database what to show and what not to when the site is loaded up. Now, I need to be able to take the value that is on the end of the url, this unique uid that corresponds with their preferences in the db, accessable on run time. Meaning that when someone types in this custom url, I need to be able to show the name of the person whose portfolio is being viewed BEFORE password authentication takes place... If I could get the URL, I suppose I could parse through it to find the necessary UID...but how do I get the url? Maybe I am just missing something here, but if anyone has any thoughts or ideas, it would be appreciated!! Thanks

  • Choosing the right and learning assembler for compiler-writing

    - by X A
    I'm writing a compiler and I have gone through all the steps (tokenizing, parsing, syntax tree structures, etc.) that they show you in all the compiler books. (Please don't comment with the link to the "Resources for writing a compiler" question!). I have chosen to use NASM together with alink as my backend. Now my problem is: I just can't find any good resources for learning NASM and assembly in general. The wikibook (german) on x86 assembly is horrible. They don't even explain the code they write there, I currently can't even get simple things like adding 1 to 2 and outputting the result working. Where can I learn NASM x86 assembly?

  • Help with python list-comprehension

    - by leChuck
    A simplified version of my problem: I have a list comprehension that i use to set bitflags on a two dimensional list so: s = FLAG1 | FLAG2 | FLAG3 [[c.set_state(s) for c in row] for row in self.__map] All set_state does is: self.state |= f This works fine but I have to have this function "set_state" in every cell in __map. Every cell in __map has a .state so what I'm trying to do is something like: [[c.state |= s for c in row] for row in self.map] or map(lambda c: c.state |= s, [c for c in row for row in self.__map]) Except that neither works (Syntax error). Perhaps I'm barking up the wrong tree with map/lamda but I would like to get rid on set_state. And perhaps know why assignment does not work in the list-comprehension

  • Modular HTML in Adobe AIR? Is It Possible?

    - by Greg Bulmash
    When I write HTML with a PHP backend, I usually have a single header file and a single footer file with some PHP variables in them. The base skeleton for every page calls the header, contains the body content, and then calls the footer. That way, if I want to make changes to the header sitewide, I change one file. I'm working on developing the UI in my first Adobe AIR app and I'm wondering if there's some way to include such files in an HTML based page template there. Obviously, with the file read/write abilities in AIR, I can write a Javascript routine to pull data from a header file, parse it, and inject it into a placeholder. It just seems like such a kludge. I'm thinking there's gotta be some simple way to import a block of HTML into a page without an iFrame or complex post-processor. Something like a PHP include statement or perhaps the old Server Side Includes. Any methods you guys can recommend?

  • Java BufferedReader behavior in CSV vs TXT file

    - by Gabriel
    If i try to read a CSV file called csv_file.csv. The problem is that when i read lines with BufferedReader.readLine() it skips the first line with months. But when i rename the file to csv_file.txt it reads it allright and it's not skipping the first line. Is there an undocumented "feature" of BufferedReader that i'm not aware? Example of file: Months, SEP2010, OCT2010, NOV2010 col1, col2, col3, col4, col5 aaa,,sdf,"12,456",bla bla bla, xsaffadfafda and so on, and so on, "10,00", xxx, xxx The code: FileInputStream stream = new FileInputStream(UploadSupport.TEMPORARY_FILES_PATH+fileName); BufferedReader br = new BufferedReader(new InputStreamReader(stream, "UTF-8")); String line = br.readLine(); String months[] = line.split(","); while ((line=br.readLine())!=null) { /*parse other lines*/ }

  • How can a string timestamp with hours 0 to 24 be parsed

    - by user897052
    I am trying to parse a string timestamp of format "yyyyMMddHHmmss" with DateTime.ParseExact(). The catch is I must allow for an hour value of "24" (i.e. hours can be from 0 to 24; Note: I can't control the input values.) and, of course, that results in an exception. Are there any settings/properties I can set instead of manually parsing/using regex's? If not, any efficient parsing ideas? ex. DateTime.ParseExact("20120911240000", "yyyyMMddHHmmss", System.Globalization.CultureInfo.InvariantCulture); hour 24 means hour 0 of next day (so day + 1, hour = 0)

  • Asynchronous database update in Django?

    - by Mark
    I have a big form on my site. When the users fill it out and submit it, most of the data just gets dumped to the database, and then they get redirected to a new page. However, I'd also like to use the data to query another site, and then parse the results. That might take a bit longer. It's not essential that the user sees these results right away, so I was wondering if it's possible to asynchronously call a function that will handle this, and then return an HttpResponse from my view like usual without making them wait? If so... how? Any particular libraries I should look at?

  • DOM class injection in PHP

    - by Adam Kiss
    idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?

  • Parsing HTML "Visually"

    - by Midhat
    OKay I am at loss how to name this question. I have some HTML files, probably written by lord Lucifier himself, that I need to parse. It consists of many segments like this, among other html tags <p>HeadingNumber</p> <p style="text-indent:number;margin-top:neg_num ">Heading Text</p> <p>Body</p> Notice that the heading number and text are in seperate p tags, aligned in a horizontal line by css. the css may be whatever Lucifier fancies, a mixture of indents, paddings, margins and positions. However that line is a single object in my business model and should be kept as such. So How do I detect whether two p elements are visually in a single line and process them accordingly. I believe the HTML files are well formed if it helps.

  • VB6 Parser/Lexer/Scripter

    - by rlb.usa
    I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them. I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before. My question is: Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?

    I've a large number of models (120+) and I would like to let users of my application export all of the data from them in XML format. I looked at django-piston, but I would like to do this with minimum code. Basically I'd like to have something like this: GET /export/applabel/ModelName/ Would stream all instances of ModelName in applabel together with it's tree of related objects . I'd like to do this without writing code for each model. What would be the best way to do this?

  • Use 'let' in 'if' expression

    - by demas
    I need a function that works like this: foo :: Integer -> Integer -> [Integer] foo a b = do let result = [] let Coord x y = boo a b if x > 0 let result = result ++ [3] if y > 0 let result = result ++ [5] if x < a let result = result ++ [7] if y < b let result = result ++ [9] result I can not use the guards because the result can have more then one element. But as I see I can not use 'let' in the 'if' expression: all_possible_combinations.hs:41:14: parse error on input `let' How can I check multiple expressions and add new elements in the list? I search not only imperative solution, but the functional one.

  • Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

    - by Ori Osherov
    Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

  • Can I pass events like key strokes to another control in Silverlight?

    - by herzmeister der welten
    Can I pass events like key strokes to another control in Silverlight? Imagine I'm in a custom control that contains a Textbox and a Treeview. I'm listening to a Key event for the TextBox. When the user pushes the Arrow Up or Arrow Down key, I want the Treeview to behave as if it's itself who received that event, i.e. it should move the current selection up or down. The user shouldn't lose focus on the TextBox though so that they can continue typing. Is this possible? I don't want to set the selection manually on the Treeview because it has no easy MoveSelectionUp() or MoveSelectionDown() method, so I would have to duplicate that functionality which is not so trivial especially when the tree is databound and loads nodes on demand.

  • What's the deal with char.GetNumericValue?

    - by mgroves
    I was working on Project Euler 40, and was a bit bothered that there was no int.Parse(char). Not a big deal, but I did some asking around and someone suggested char.GetNumericValue. GetNumericValue seems like a very odd method to me: Takes in a char as a parameter and returns...a double? Returns -1.0 if the char is not '0' through '9' So what's the reasoning behind this method, and what purpose does returning a double serve? I even fired up Reflector and looked at InternalGetNumericValue, but it's just like watching Lost: every answer just leads to another question.
