• Subversion Copy Hook on Windows

  - by GeoSQL

  Hi I am working on a web based project in my free time. I have SVN set up on my machine (running XP). What I would like to do is have a copy of my repository copied to the htdocs folder (Dev machine) post-commit via a hook. That way I can test my changes in a browser. I know that I can write up a .bat file, but I'm not sure what the syntax would be. I can do a basic DOS Copy command, but I saw one example that provided a username and password to SVN at copy time. Do I need to do this? Can someone point me in the right direction as far a syntax for the .bat file? Or maybe even suggest a better method. Thanks

• How to keep statefull web clients in sync, when multiple clients are looking at the same data?

  - by Hilbrand

  In a RIA web client, created with GWT, the state is maintained in the web client, while the server is (almost) stateless (this is the preferred technique to keep the site scalable). However, if multiple users looking at the same data in their browser and one user changes something, which is send to the server and stored in the database, the other users still have the old data in their browser state. For example a tree is shown and one of the users adds/removes an item from the tree. Since there can be a lot of state in the client, what is the best technique to keep the state in the clients in sync? Are there any java frameworks that take care of this?

• Error when creating database in MySQL using Netbeans 6.8

  - by nix

  I am trying to create a database using MySQL statements in NetBeans 6.8. However, I keep getting Error code 1064. I don't know what the problem is really since the same statements work in NetBeans 6.0. Here is the error: Error code 1064, SQL state 42000: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '; /*!40000 ALTER TABLE students ENABLE KEYS */; -- -- Definition of table `w' at line 1016 Line 46, column 1

• C++ a map to a 2 dimensional vector

  - by user1701545

  I want to create a C++ map where key is, say, int and value is a 2-D vector of double: map myMap; suppose I filled it and now I would like to update the second vector mapped by each key (for example divide each element by 2). How would I access that vector iteratively? The "itr-second[0]" syntax in the statement below is obviously wrong. What would be the right syntax for that action? for(std::map<in, vector<vector<double> > > itr = myMap.begin(); itr != myMap.end();++itr) { for(int i = 0;i < itr->second[0].size();++i) { itr->second[0][i] /= 2; } } thanks, rubi

• how to handle JavaScript objects with colons in key names?

  - by Ethan

  There is a syntax error in the following code: <!DOCTYPE html> <html> <body> Hello World! <script type="text/javascript"> var obj = {'a:b': '1'}; alert(obj.a:b); // syntax error </script> </body> </html> So how to handle JavaScript objects with colons in key names? I have to do this because I need to handle a feed in jsonp format from a remote server which I do not have control over, and there are colons in the key names of the returned jsonp (because the jsonp is converted from XML with namespaces in tags).

• An array of structures in C...

  - by 00010000

  For the life of me I can't figure out the proper syntax for creating an array of structures in C. I tried this: struct foo { int x; int y; } foo[][] = { { { 1, 2 }, { 4, 5 }, { -1, -1 } }, { { 55, 44 } { 100, 200 }, } }; So for example foo[1][0].x == 100, foo[0][1].y == 5, etc. But GCC spits out a lot of errors. If anyone could provide the proper syntax that'd be great. EDIT: Okay, I tried this: struct foo { const char *x; int y; }; struct foo bar[2][] = { { { "A", 1 }, { "B", 2 }, { NULL, -1 }, }, { { "AA", 11 }, { "BB", 22 }, { NULL, -1 }, }, { { "ZZ", 11 }, { "YY", 22 }, { NULL, -1 }, }, { { "XX", 11 }, { "UU", 22 }, { NULL, -1 }, }, }; But GCC gives me "elements of array bar have incomplete type" and "excess elements in array initializer".

• Best practices to keep up a diverging branch of code

  - by JS_is_bad

  I'm in a situation where some minor patches I've submitted to an open-source project were ignored or explicitly not accepted. I consider them useful, but more important is that I need the functionality they implement. I don't want to push my ideas and suggestions anymore to the main contributors, because I don't want to turn this into an ego issue. I've decided that my best bet would be just to use what I wrote for my own purposes. I don't want to fork the whole source code tree because I like how things are generally working, I'm just not happy with details. But I do realize that the project will evolve and I would like to use the new features that will eventually appear. I understand that I'll have to merge all new things into my own source tree. Are there any best practices for this scenario?

• Using ANTLR with Left-Recursive Rules

  - by CNevin561

  Basically Ive written a Parse for a language with just basic arithmetic operators ( +, -, * / ) etc, but for the minus and plus cases, the Abstract Syntax Tree which is generated has parsed them as right associative when they need to be left associative. Having a googled for a solution, i found a tutorial that suggests rewriting the rule from: Expression ::= Expression <operator> Term | Term as Expression ::= Term <operator> Expression*. However in my head this seems to generate the tree the wrong way round. Any pointers on a way to resolve this issue?

• Can't figure out what's wrong with my php/sql statement

  - by Olegious

  So this is probably a dumb beginner question, but I've been looking at it and can't figure it out. A bit of background: just practicing making a web app, a form on page 1 takes in some values from the user, posts them to the next page which contains the code to connect to the DB and populate the relevant tables. I establish the DB connection successfully, here's the code that contains the query: $conn->query("SET NAMES 'utf9'"); $query_str = "INSERT INTO 'qa'.'users' ('id', 'user_name','password' ,'email' ,'dob' ,'sx') VALUES (NULL, $username, $password, $email, $dob, $sx);"; $result = @$conn->query($query_str); Here's the error that is returned:Insert query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''qa'.'users' ('id', 'user_name' ,'password' ,'email' ,'dob' ,'s' at line 1 Thanks in advance!

• Bash, Concatenating 2 strings to reference a 3rd variable

  - by Im Fine

  I have a bash script I am having some issues with concatenating 2 variables to call a 3rd. Here is a simplification of the script, but the syntax is eluding me after reading the docs. server_list_all="server1 server2 server3"; var1 = "server"; var2 = "all"; echo $(($var1_list_$var2)); This is about as close as I get to the right answer, it acknowledges the string and tosses an error on tokenization. syntax error in expression (error token is "server1 server2 server3.... Not really seeing anything in the docs for this, but it should be doable. EDIT: Cleaned up a bit

• how to get all the menu items below a certain parent in drupal?

  - by sprugman

  I really only need the mlid and title text for the first level below a certain menu item. Here's what I'm doing at the moment. (It works, but I suspect there may be a more drupal-y way.): /** * Get all the children menu items below 'Style Guide' and put them in this format: * $menu_items[mlid] = 'menu-title' * @return array */ function mymod_get_menu_items() { $tree = menu_tree_all_data('primary-links'); $branches = $tree['49952 Parent Item 579']['below']; // had to dig for that ugly key $menu_items = array(); foreach ($branches as $menu_item) { $menu_items[$menu_item['link']['mlid']] = $menu_item['link']['title']; } return $menu_items; } Is there?

• How do I sync two local file structures.

  - by James

  Hi, I have two large source trees. One of them has some out of date image files. I would like to automatically update all the old image files (png, jpg, gif) in one source tree with the up to date image files in the other source tree. I am using Windows 7 but I have Cygwin installed. I have tried using rsync so far but with no success. I was hoping I could do something like: rsync -r *.png newSourceTree oldSourceTree Any help would be much appreciated.

• How to crosscheck two tables and insert relevant data into a new table in MYSQL?

• How can I disallow all HTML using markdown (PHP and JS)?

  - by peterjwest

  I'm using the PHP markdown library: http://michelf.com/projects/php-markdown/ and the Javascript markdown library: http://attacklab.net/showdown/ I want to disallow all HTML, both the versions of markdown seem to allow it indiscriminately. My first attempt was simply to escape all html entities before feeding into markdown. However this also escapes the <hyperlink> and <email> syntax, which is very useful. I'd like to escape all HTML (not remove) but preserve all markdown syntax.

• MySql. What is there error on this insert+select+where statement?

  - by acidzombie24

  What is wrong with this statement? It works with sqlite and MS sql (last time i tested it) I would like a select unless there is no match with name or email. Then i would like to insert. I have it as one statement because its easy to keep concurrent safe as one statement. (its not that complex of a statement). INSERT INTO `user_data` ( `last_login_ip`, `login_date`, ...) SELECT @0, @14 WHERE not exists (SELECT * FROM `user_data` WHERE `name` = @15 OR `unconfirmed_email` = @16 LIMIT 1); Exception You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE not exists (SELECT * FROM `user_data` WHERE `name` = 'thename' OR `unconfirmed' at line 31

• Reorganising git commits into different branches

  - by user1425706

  I am trying to reorganise my git tree so that it is structured a bit better. Basically at the moment I have a single master branch with a couple of small feature branches that split from it. I want to go back and reorder it so that the only commits in the main branch are the ones corresponding to new version numbers and then have all the in between commits reside in a separate develop branch from which the feature branches split from too. Basically I'm looking for a tool that will let me completely manually reorganise the tree. I thought maybe that interactive rebasing was what I was looking for but trying to do so in sourcetree makes it seem like it is not the right tool. Can anyone give me some advice on how best to proceed. Below is a diagram of my current structure: featureA x-x-x / \ master A-x-x-x-x-B-x-x-x-C D Desired structure: feature x-x-x / | develop x-x-x-x-x-x-x - / | | | master A - B - C - D

• Correcting an UPDATE statement (and making it more secure!)

  - by Jess

  I'm trying to a single value in my DB...When I run it through the console, it works correctly (as I'm replacing the variables with numbers and text).. However, My query is not running correctly. It's just prompting a syntax error Here is what I have: "UPDATE books SET readstatus='".$readstatus."' WHERE book_id=".$book_id; This won't work, I also tried doing something like this as I'm told this makes it a bit more secure? : "UPDATE books SET readstatus='{$readstatus}', WHERE read_id='{read_id}'"; This does not prompt any errors, but no change is happeneing to the value in the DB, I'm guessing the syntax is incorrect.
