• Syntax highlighting in MS Word document

  - by ArunSaha

  I want to insert some C/C++ source code into a Microsoft Word document. I have no problem in copying the code from source file and pasting into Word. I can do fixed-width. But, in Word, I see the code in black-and-white format; I loose the syntax highlighting as I get in the source code editor (for me, gvim). So, my question is, is there any way to do syntax highlighting of C/C++ source code in MS Word?

• Searching for a semantic syntax highlighter in Javascript

  - by Boldewyn

  OK, I know, there are literally dozens of already available syntax highlighters out there. But I want one specifically, that implements line numbers through <ol/> lists. And that reduces the number of possible candidates to one, Lighter.js. Unfortunately, that is MooTools based, and since I decided some time ago to use jQuery, I don't want to embed yet another library just for syntax highlighting. The SyntaxHighlighter does something similar, but uses tables for the line numbering, and I don't want to hack it, if there is an already available tool, too.

• java equivalent of ruby's ||= syntax

  - by brad

  I'm brand new to java, coming from a ruby world. One thing I love about ruby is the very terse syntax such as ||=. I realize of course that a compiled language is different, but I'm wondering if Java has anything similar. In particular, what I do all the time in ruby is something like: someVar ||= SomeClass.new I think this is incredibly terse, yet powerful, but thus far the only method I can think of to achieve the same thing is a very verbose: if(someVar == null){ someVar = new SomeClass() } Just trying to improve my Java-fu and syntax is certainly one area that I'm no pro.

• Xcode: code loses syntax coloring

  - by ColorMeFamous

  I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work. Is this a known issue with Xcode? For something so annoying to me, I'm not finding the plentiful discussions of it on SO and elsewhere I'd expect. And is there any command to force global syntax recoloring?

• Parsing WordPress XML, slash:comments syntax?

  - by user313653

  This is really just a syntax question. I have a PHP script that parses my WordPress feed and returns the latest posts. I also want my script to parse the # of comments, but the WordPress feed XML object for number of comments has a colon in it (slash:comments). It causes the following error: Parse error: syntax error, unexpected ':' in ... on line ... I have tried each of the following without luck: $xml->slash:comments $comments = 'slash:comments' $xml->$comments $xml->slash.':'.comments $xml->{slash:comments} $xml->{'slash:comments'} How do I parse an object with a colon?

• mysql query - syntax error - cannot find out why

  - by Phil Jackson

  Hi all, im taring my hair out over this one. A query is throwing an error: 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 'FROM, SUBJECT, DATE, READ, MAIL ) VALUES ( 'EJackson', 'dfdf', '1270974101', 'fa' at line 1 I printed out the query to see what could be the problem: INSERT INTO db.tablename ( FROM, SUBJECT, DATE, READ, MAIL ) VALUES ( 'EJackson', 'dfdf', '1270974299', 'false', 'dfdsfdsfd' ) and finaly the structure consists of: CREATE TABLE db.tablename ( `ID` int(12) NOT NULL auto_increment, `FROM` varchar(255) NOT NULL, `SUBJECT` varchar(255) NOT NULL, `DATE` varchar(255) NOT NULL, `READ` varchar(255) NOT NULL, `MAIL` varchar(255) NOT NULL, PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; I cant find anything wrong. Any Help would be much appreciated. ( db.tablename is a replacement for the actual tablename )

• Using colon syntax and variables in Sass

  - by corroded

  I am still using the old colon syntax (I prefer it more than the bracket syntax) and this particular code: a.button-link +box($main-color) +border-radius(5px) :background :color $main-color :color #fff :padding 5px generates a warning like so: DEPRECATION WARNING: On line 12, character 3 of '/Users/eumir/rails_apps/dxconnect/app/ stylesheets/partials/utilities/_link-styles.sass' Setting properties with = has been deprecated and will be removed in version 3.2. Use "background: $main-color" instead. I tried that but my background color still doesn't show up. Any help on this please? Thanks!

  New to SQL. I'm looking to create a IT asset database. Here is one of the tables created with php: mysql_query("CREATE TABLE software( id VARCHAR(30), PRIMARY KEY(id), software VARCHAR(30), key VARCHAR(30))") or die(mysql_error()); echo "Software Table Created.</br />"; This is the output from the browser when I run the script: 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 'VARCHAR(30))' at line 5 I am running a standard LAMP stack on Ubuntu Server 10.04.

• typedef declaration syntax

  - by mt_serg

  Some days ago I looked at boost sources and found interesting typedef. There is a code from "boost\detail\none_t.hpp": namespace boost { namespace detail { struct none_helper{}; typedef int none_helper::*none_t ; } // namespace detail } // namespace boost I didn't see syntax like that earlier and can't explain the sense of that. This typedef introduces name "none_t" as pointer to int in boost::detail namespace. What the syntax is? And what difference between "typedef int none_helper::*none_t" and for example "typedef int *none_t" ?

• Real world examples of tree structures

  - by Arec Barrwin

  I'm looking for some examples of tree structures that are used in commercial/free software projects, modern or old. I can see examples on wikipedia, but I am looking for more concrete examples and how they're used. For example primary keys in databases are (from what I've read) stored in BST structure or a variation of the BST (feel free to correct me on this) My question isn't limited Binary Search Trees (BSTs), it can include any variation such as red-black, AVL and so on.

• Simpler array declaration syntax in c++

  - by AareP

  In the spirit of Go-language, where simpler syntax is considered pretty important, here's a proposal for simpler array declaration in c++: int value; int_1 list; int_2 table; int_3 cube; RECT rect; RECT_1 rects; Using typedefs this can expand to: int value; vector<int> list; vector<int> table; vector<int> cube; RECT rect; vector<RECT> rects; Would you use it, or is there such a thing as too simple syntax?

• syntax to express mathematical formula concisely in your language of choice

  - by aaa

  hello. I am developing functional domain specific embedded language within C++ to translate formulas into working code as concisely and accurately as possible. Right now my language looks something like this: // implies two nested loops j=0:N, i=0,j (range(i) < j < N)[T(i,j) = (T(i,j) - T(j,i))/e(i+j)]; // implies summation over above expression sum(range(i) < j < N))[(T(i,j) - T(j,i))/e(i+j)]; I am looking for possible syntax improvements/extensions or just different ideas about expressing mathematical formulas as clearly and precisely as possible. Can you give me some syntax examples relating to my question which can be accomplished in your language of choice which consider useful. In particular, if you have some ideas about how to translate the above code segments, I would be happy to hear them Thank you

• Vim syntax/compile-time error highlighting

  - by Tim Nordenfur

  Is there a Vim script that periodically tries to compile/interpret the code that I'm working on, and highlights syntax errors? I'd like it to point out that something is wrong between these lines: int a = 42 cout << a << endl; Such a thing would save me loads of time. I'm primarily searching for a Perl-syntax checker, but I'd also be interested in similar plugins for other languages. Update: Another error I'd like it to point out: int a == 42; cout << a << endl;

• PHP MySQL Syntax Error 'You have an error in your SQL syntax'

  - by Alec

  I cannot figure out the issue with my code here. I am trying to take info from the table, then subtract 1 second from Current_Time which looks like '2:00'. The problem is, I get: "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 'Current_Time) VALUES('22')' at line 1" I don't even understand where it gets 22 from. Thanks, I really appreciate it. if (isset($_GET['id']) && isset($_GET['time'])) { mysql_select_db("aleckaza_pennyauction", $connection); $query = "SELECT Current_Time FROM Live_Auctions WHERE ID='1'"; $results = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($results)) { $newTime = $row['Current_Time'] - 1; $query = "INSERT INTO Live_Auctions(Current_Time) VALUES('".$newTime."')"; $results = mysql_query($query) or die(mysql_error()); } }

• python - selenium script syntax error

  - by William Hawkes

  Okay, I used selenium to test some automation, which I got to work. I did an export of the script for python. When I tried to run the python script it generated, it gave me a "SyntaxError: invalid syntax" error message. Here's the python script in question: from selenium import selenium import unittest, time, re class WakeupCall(unittest.TestCase): def setUp(self): self.verificationErrors = [] self.selenium = selenium("localhost", 4444, "*chrome", "http://the.web.site") self.selenium.start() def test_wakeup_call(self): sel = self.selenium sel.open("/index.php#deposit") sel.wait_for_page_to_load("30000") sel.click("link=History") sel.wait_for_page_to_load("30000") try: self.failUnless(sel.is_text_present("key phrase number 1.")) except AssertionError, e: self.verificationErrors.append(str(e)) The last line is what generated the "SyntaxError: invalid syntax" error message. A "^" was under the comma. The rest of the script goes as follows: def tearDown(self): self.selenium.stop() self.assertEqual([], self.verificationErrors) if name == "main": unittest.main()

• Conditional Drag and Drop Operations in Flex/AS3 Tree

  - by user163757

  Good day everyone. I am currently working with a hierarchical tree structure in AS3/Flex, and want to enable drag and drop capabilities under certain conditions: Only parent/top level nodes can be moved Parent/top level nodes must remain at this level; they can not be moved to child nodes of other parent nodes Using the dragEnter event of the tree, I am able to handle condition 1 easily. private function onDragEnter(event:DragEvent):void { // only parent nodes (map layers) are moveable event.preventDefault(); if(toc.selectedItem.hasOwnProperty("layer")) DragManager.acceptDragDrop(event.target as UIComponent); else DragManager.showFeedback(DragManager.NONE); } Handling the second condition is proving to be a bit more difficult. I am pretty sure the dragOver event is the place for logic. I have been experimenting with calculateDropIndex, but that always gives me the index of the parent node, which doesn't help check if the potential drop location is acceptable or not. Below is some pseudo code of what I am looking to accomplish. private function onDragOver(e:DragEvent):void { // if potential drop location has parents // dont allow drop // else // allow drop } Can anyone provide advice how to implement this?

• Java Binary Tree. Priting InOrder traversal

  I am having some problems printing an inOrder traversal of my binary tree. Even after inserting many items into the tree it's only printing 3 items. public class BinaryTree { private TreeNode root; private int size; public BinaryTree(){ this.size = 0; } public boolean insert(TreeNode node){ if( root == null) root = node; else{ TreeNode parent = null; TreeNode current = root; while( current != null){ if( node.getData().getValue().compareTo(current.getData().getValue()) <0){ parent = current; current = current.getLeft(); } else if( node.getData().getValue().compareTo(current.getData().getValue()) >0){ parent = current; current = current.getRight(); } else return false; if(node.getData().getValue().compareTo(parent.getData().getValue()) < 0) parent.setLeft(node); else parent.setRight(node); } } size++; return true; } /** * */ public void inOrder(){ inOrder(root); } private void inOrder(TreeNode root){ if( root.getLeft() !=null) this.inOrder(root.getLeft()); System.out.println(root.getData().getValue()); if( root.getRight() != null) this.inOrder(root.getRight()); } }

• Logic for family tree program

  - by david robers

  Hi All, I am creating a family tree program in Java, or at least trying to. I have developed several classes: Person - getters and setter for name gender age etc FamilyMember - extends Person getters and setters for setting arents and children Family - which consists of multiple family members and methods for adding removing members FamilyTree which is the main class for setting relationships. I have two main problems: 1) I need to set the relationships between people. Currently I am doing: FamilyMember A, FamilyMember B B.setMother(A); A.setChild(B); The example above is for setting a mother child relationship. This seems very clunky. Its getting very long winded to implement all relationships. Any ideas on how to implement multiple relationships in a less prodcedural way? 2) I have to be able to display the family tree. How can I do this? Are there any custom classes out there to make life easier? Thanks for your time...

• Creating subtree from tree which is represented in xml - python

  - by Jay

  Hi I have an XML (in the form of tree), I require to create sub-tree out of it. For ex: <a> <b> <c>Hello</c> <d> <e>Hi</e> </a> Subtree would be <root> <a> <b> <c>Hello</c> </b> </a> <a> <d> <e>Hi</e> </d> </a> </root> What is the best XML library in python to do it? Any algorithm that already does this would also be helpful. Note: the XML doc won't be that big, it will easily fit in memory.

• How to exclude rows where matching join is in an SQL tree

  - by Greg K

  Sorry for the poor title, I couldn't think how to concisely describe this problem. I have a set of items that should have a 1-to-1 relationship with an attribute. I have a query to return those rows where the data is wrong and this relationship has been broken (1-to-many). I'm gathering these rows to fix them and restore this 1-to-1 relationship. This is a theoretical simplification of my actual problem but I'll post example table schema here as it was requested. item table: +------------+------------+-----------+ | item_id | name | attr_id | +------------+------------+-----------+ | 1 | BMW 320d | 20 | | 1 | BMW 320d | 21 | | 2 | BMW 335i | 23 | | 2 | BMW 335i | 34 | +------------+------------+-----------+ attribute table: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | | 23 | AC | 24 | | 24 | Climate control | 0 | .... | 34 | Leather seats | 0 | +---------+-----------------+------------+ A simple query to return items with more than one attribute. SELECT item_id, COUNT(DISTINCT(attr_id)) AS attributes FROM item GROUP BY item_id HAVING attributes > 1 This gets me a result set like so: +-----------+------------+ | item_id | attributes | +-----------+------------+ | 1 | 2 | | 2 | 2 | | 3 | 2 | -- etc. -- However, there's an exception. The attribute table can hold a tree structure, via parent links in the table. For certain rows, parent_id can hold the ID of another attribute. There's only one level to this tree. Example: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | .... I do not want to retrieve items in my original query where, for a pair of associated attributes, they related like attributes 20 & 21. I do want to retrieve items where: the attributes have no parent for two or more attributes they are not related (e.g. attributes 23 & 34) Example result desired, just the item ID: +------------+ | item_id | +------------+ | 2 | +------------+ How can I join against attributes from items and exclude these rows? Do I use a temporary table or can I achieve this from a single query? Thanks.

• Getting tree construction with ANTLR

With the input 1+2, I want to have a tree ^('+' ^(INT 1) ^(INT 2)). Or similar. grammar T; options { output=AST; language=Python; ASTLabelType=CommonTree; } start : e - e ; e : t ep - ??? ; ep : | '+' t ep - ??? ; t : f tp - ??? ; tp : | '*' f tp - ??? ; f : INT | '(' e ')' - e ; INT : '0'..'9'+ ; WS: (' '|'\n'|'\r')+ {$channel=HIDDEN;} ;

• What do I do with a Concrete Syntax Tree?

  - by Cap

  I'm using pyPEG to create a parse tree for a simple grammar. The tree is represented using lists and tuples. Here's an example: [('command', [('directives', [('directive', [('name', 'retrieve')]), ('directive', [('name', 'commit')])]), ('filename', [('name', 'f30502')])])] My question is what do I do with it at this point? I know a lot depends on what I am trying to do, but I haven't been able to find much about consuming/using parse trees, only creating them. Does anyone have any pointers to references I might use? Thanks for your help.

• How do I get Dreamweaver to deploy syntax highlighting for full script CFC's?

  - by Mel

  Is there a way to get Dreamweaver CS4 to use syntax highlighting when writing full script CFCs? If the document type is .cfc and they syntax is fullscript, there is no syntax highlighting; the code will be in black text... For example, the following block of code will appear without syntax highlighting: component extends="whatever" output="false" { public void foo() { } } While the tag equivalent would be highlighted normally: <cfcomponent extends="whatever" output="false"> <cffunction name="foo" returnType="void" access="public"> </cffunction> </cfcomponent>
