• Publishing toolchain

  - by Marcelo de Moraes Serpa

  Hello all, I have a book project which I'd like to start sooner than later. This would follow an agile-like publishing workflow, i.e: publish early and often. It is meant to be self-publsihed by me and I'm not really looking to paper-publish it, even though we never know. If I weren't a geek, I'd probably have already started writting in Word or any other WYSIWYG tool and just export to PDF. However, we know it is not the best solution, and emacs rules my text-editing life, so, the output format should be as simple as possible and be text-based. I've thought about the following options: 1) Use orgmode and export to PDF; 2) Use markdown mode and export to PDF; 3) Use something similar to what the guys @ Pragmatic Progammers do: A XML + XSLT + LaTeX. More complex, but much more control over the style. Any other ideas / references ? I want to start writting as soon as possible. In fact, I already have a draft in an org-formatted file. However, I do want to have and use the full power of LaTex later on to format it the way I want and make it look fabulous :) Thanks in advance, Marcelo.

• Can't ssh to ec2 permission denied (publickey)

  - by Chris Barnes

  I have existing instances running and I can connect to them fine.

• LINQ self referencing query

  - by Chris

  I have the following SQL query: select p1.[id], p1.[useraccountid], p1.[subject], p1.[message], p1.[views], p1.[parentid], case when p2.[created] is null then p1.[created] else p2.[created] end as LastUpdate from forumposts p1 left join ( select parentid, max(created) as [created] from forumposts group by parentid ) p2 on p2.parentid = p1.id where p1.[parentid] is null order by LastUpdate desc Using the following class: public class ForumPost : PersistedObject { public int Views { get; set; } public string Message { get; set; } public string Subject { get; set; } public ForumPost Parent { get; set; } public UserAccount UserAccount { get; set; } public IList<ForumPost> Replies { get; set; } } How would I replicate such a query in LINQ? I've tried several variations, but I seem unable to get the correct join syntax. Is this simply a case of a query that is too complicated for LINQ? Can it be done using nested queries some how? The purpose of the query is to find the most recently updated posts i.e. replying to a post would bump it to the top of the list. Replies are defined by the ParentID column, which is self-referencing.

• What is the recommended coding style for PowerShell?

  - by stej

  Is there any recommended coding style how to write PowerShell scripts? It's not about how to structure the code (how many functions, if to use module, ...). It's about 'how to write the code so that it is readable'. In programming languages there are some recommended coding styles (what to indent, how to indent - spaces/tabs, where to make new line, where to put braces,...), but I haven't seen any suggestion for PowerShell. What I'm interested particularly in: How to write parameters function New-XYZItem ( [string] $ItemName , [scriptblock] $definition ) { ... (I see that it's more like 'V1' syntax) or function New-PSClass { param([string] $ClassName ,[scriptblock] $definition )... or (why to add empty attribute?) function New-PSClass { param([Parameter()][string] $ClassName ,[Parameter()][scriptblock] $definition )... or (other formatting I saw maybe in Jaykul's code) function New-PSClass { param( [Parameter()] [string] $ClassName , [Parameter()] [scriptblock] $definition )... or ..? How to write complex pipeline Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc or (name of cmdlet on new line) Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc | and what if there are -begin -process -end params? how to make it the most readable? Get-SomeData -param1 abc -param2 xyz | % -begin { init } -process { Process-somehow2 ... } -end { Process-somehow3 ... } | % -begin { } .... or Get-SomeData -param1 abc -param2 xyz | % ` -begin { init } ` -process { Process-somehow2 ... } ` -end { Process-somehow3 ... } | % -begin { } .... the indentitation is important here and what element is put on new line as well. I have covered only questions that come on my mind very frequently. There are some others, but I'd like to keep this SO question 'short'. Any other suggestions are welcome.

• zend_form display group inside foreach

  - by Mike

  I want to create a display group generated from foreach() clause output. I can't seem to get the syntax correct. Here's the business logic: for each category row find the associated fees output the category description as a label and the fees as radio buttons then create a display group with the fees as the group elements and the category description as the legend. I then have a style sheet format the elements on the page. and here's the code: foreach ($categoryData as $categoryRow) { $fees[$i] = new Zend_Form_Element_Radio("fees[$i]"); $fees[$i]->setDescription(strval($categoryRow['description'])); foreach ($feeData as $feeRow) { if ($feeRow['categories_idCategory'] == $categoryRow['idCategory']){ $fees[$i] ->addMultiOption($feeRow['idFees'] . '-' . $feeRow['categories_idCategory'], $feeRow['amount'] . '-' . $feeRow['name']); } } $fees[$i]->setRequired(TRUE); $this->addElements(array($fees[$i])); $this->addDisplayGroup($feeRow['name'], 'feeGroup',array('legend' => strval($feeRow['description']))); $i++; } I tried placing the addDisplayGroup() code within the foreach(), but I get the error: Message: No valid elements specified for display group So, my guess is that I'm making some kind of novice mistake that you experts will spot right away. I appreciate your time and attention to this matter.

• Asp.net mvc 2 .net 4.0 error when View model type is Tuple with more than 4 items

  - by Bojan

  When I create strongly typed View in Asp.net mvc 2, .net 4.0 with model type Tuple I get error when Tuple have more than 4 items example 1: type of view is Tuple<string, string, string, string> (4-tuple) and everything works fine view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/WebUI.Master" Inherits="System.Web.Mvc.ViewPage<Tuple<string, string, string, string>>" %> controller: var tuple = Tuple.Create("a", "b", "c", "d"); return View(tuple); example 2: type of view is Tuple<string, string, string, string, string> (5-tuple) and I have this error: Compiler Error Message: CS1003: Syntax error, '>' expected view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/WebUI.Master" Inherits="System.Web.Mvc.ViewPage<Tuple<string, string, string, string, string>>" %> controller: var tuple = Tuple.Create("a", "b", "c", "d", "e"); return View(tuple); example 3 if my view model is of type dynamic I can use both 4-tuple and 5-tuple and there is no error on page view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/WebUI.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> controller: dynamic model = new ExpandoObject(); model.tuple = Tuple.Create("a", "b", "c", "d"); return View(model); or view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/WebUI.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> controller: dynamic model = new ExpandoObject(); model.tuple = Tuple.Create("a", "b", "c", "d", "e"); return View(model); Even if I have something like Tuple<string, Tuple<string, string, string>, string> 3-tuple and one of the items is also a tuple and sum of items in all tuples is more than 4 I get the same error, Tuple<string, Tuple<string, string>, string> works fine

• Nested Routes and Parameters for Rails URLs (Best Practice)

  - by viatropos

  Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

• jQuery Validation Plugin: Validating Checkboxes with Different Names

  - by Michael

  I have a set of 4 checkboxes, all with different names, and require that at least 1 is checked. I know there are a few posts on here already trying to answer this question. The solution that seems to be most logical to me is the answer posted on Question 1734840, but I can't seem to get it working! What's wrong with my code? Or any other new coding ideas to get this working? I have set the class on all of them to 'require-one'. My jQuery code is $(document).ready(function(){ $("#itemForm").validate({ highlight: function(element, errorClass, validClass) { $(element).addClass(errorClass).removeClass(validClass); $(element.form).find("label[for=" + element.name + "]") .addClass("radioerror"); }, unhighlight: function(element, errorClass, validClass) { $(element).removeClass(errorClass).addClass(validClass); $(element.form).find("label[for=" + element.name + "]") .removeClass("radioerror"); }, rules: { 'require-one': { required : { depends: function(element) { var allBoxes = $('.require-one'); if (allBoxes.filter(':checked').length == 0) { if (allBoxes.eq(element).length != 0) { return true; } } return false; } } } , }, errorPlacement: function(error, element) { if ( element.is("#other_descrip") ) error.appendTo("#othererror" ); if ( element.is("#itemlist") ) error.appendTo("#itemerror" ); } }); });

• dumping the source code for an anonymous function

  - by intuited

  I'm working with a lot of anonymous functions, ie functions declared as part of a dictionary, aka "methods". It's getting pretty painful to debug, because I can't tell what function the errors are happening in. Vim's backtraces look like this: Error detected while processing function NamedFunction..2111..2105: line 1: E730: using List as a String This trace shows that the error occurred in the third level down the stack, on the first line of anonymous function #2105. IE NamedFunction called anonymous function #2111, which called anonymous function #2105. NamedFunction is one declared through the normal function NamedFunction() ... endfunction syntax; the others were declared using code like function dict.func() ... endfunction. So obviously I'd like to find out which function has number 2105. Assuming that it's still in scope, it's possible to find out what Dictionary entry references it by dumping all of the dictionary variables that might contain that reference. This is sort of awkward and it's difficult to be systematic about it, though I guess I could code up a function to search through all of the loaded dictionaries for a reference to that function, watching out for circular references. Although to be really thorough, it would have to search not only script-local and global dictionaries, but buffer-local dictionaries as well; is there a way to access another buffer's local variables? Anyway I'm wondering if it's possible to dump the source code for the anonymous function instead. This would be a lot easier and probably more reliable.

• Shift-reduce: when to stop reducing?

  - by Joey Adams

  I'm trying to learn about shift-reduce parsing. Suppose we have the following grammar, using recursive rules that enforce order of operations, inspired by the ANSI C Yacc grammar: S: A; P : NUMBER | '(' S ')' ; M : P | M '*' P | M '/' P ; A : M | A '+' M | A '-' M ; And we want to parse 1+2 using shift-reduce parsing. First, the 1 is shifted as a NUMBER. My question is, is it then reduced to P, then M, then A, then finally S? How does it know where to stop? Suppose it does reduce all the way to S, then shifts '+'. We'd now have a stack containing: S '+' If we shift '2', the reductions might be: S '+' NUMBER S '+' P S '+' M S '+' A S '+' S Now, on either side of the last line, S could be P, M, A, or NUMBER, and it would still be valid in the sense that any combination would be a correct representation of the text. How does the parser "know" to make it A '+' M So that it can reduce the whole expression to A, then S? In other words, how does it know to stop reducing before shifting the next token? Is this a key difficulty in LR parser generation?

• Using an existing IQueryable to create a new dynamic IQueryable

  - by dnoxs

  I have a query as follows: var query = from x in context.Employees where (x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2 order by x.Surname select x; The above is the original query and returns let's say 1000 employee entities. I would now like to use the first query to deconstruct it and recreate a new query that would look like this: var query = from x in context.Employees where ((x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2) && (x,i) i % 10 == 0 order by x.Surname select x.Surname; This query would return 100 surnames. The syntax is probably incorrect, but what I need to do is attach an additional where clause and modify the select to a single field. I've been looking into the ExpressionVisitor but I'm not entirely sure how to create a new query based on an existing query. Any guidance would be appreciated. Thanks you.

• WCF for a shared data access

  - by Audrius

  Hi all, I have a little experience with WCF and would like to get your opinion/suggestion on how the following problem can be solved: A web service needs to be accessible from multiple clients simultaneously and service needs to return a result from a shared data set. The concrete project I'm working on has to store a list of IP addresses/ranges. This list will be queried by a bunch of web servers for a validation purposes and we speak of a couple of thousand or more queries per minute. My initial draft approach was to use Windows service as a WCF host with service contract implementing class that is decorated with ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple) that has a list object and a custom locking for accessing it. So basically I have a WCF service singleton with a list = shared data - multiple clients. What I do not like about it is that data and communication layers are merged into one and performance wise this doesn't feel "right". What I really really (- want is Windows service running an instance of IP list holding container class object, a second service running WCF service contract implementation and a way the latter querying the former in a nice way with a minimal blocking. Using another WCF channel would not really take me far away from the initial draft implementation or would it? What approach would you take? Project is still in a very early stage so complete design re-do is not out of question. All ideas are appreciated. Thanks! UPDATE: The data set will be changed dynamically. Web service will have a separate method to add IP or IP range and on top of that there will be a scheduled task that will trigger data cleanup every 10-15 minutes according to some rules. UPDATE 2: a separate benchmark project will be kicked up that should use MSSQL as a data backend (instead on in-memory list).

• Symfony / Doctrine - How to filter form field by property in related model

  - by Dan

  I have a UserForm class which has a select list populated from a related model (specified by a foreign relationship in the yml) like so: $this->setWidget('report_id', new sfWidgetFormDoctrineChoice(array('model' => $this->getRelatedModelName('Report')))); I'd like to filter the Report objects that come from this relation by one of the Report fields, "active" such that only Reports with active=1 appear in the form. I have a method, ReportTable::GetActiveReports() that performs the appropriate query and returns the filtered reports. So one option is to populate the Widget with the results of that function. Any tips on the syntax to do that? It seems to me the cleaner way is to use the UserFormFilter class to filter the reports by active=1 there. Unfortunately I couldn't find any documentation on how to use form filters (or really what they are), so maybe this is not the right solution. Is a Form Filter the appropriate tool for this job? It seems I should use the Doctrine_Record_Filter_Standard class as defined here: http://www.doctrine-project.org/api/orm/1.2/doctrine/doctrine_record_filter_standard.html But it's not clear to me the appropriate usage. Any guidance would be helpful. Thanks! Dan

• Settings variable values in a Moq Callback() call

  - by Adam Driscoll

  I think I may be a bit confused on the syntax of the Moq Callback methods. When I try to do something like this: IFilter filter = new Filter(); List<IFoo> objects = new List<IFoo> { new Foo(), new Foo() }; IQueryable myFilteredFoos = null; mockObject.Setup(m => m.GetByFilter(It.IsAny<IFilter>())).Callback( (IFilter filter) => myFilteredFoos = filter.FilterCollection(objects)).Returns(myFilteredFoos.Cast<IFooBar>()); This throws a exception because myFilteredFoos is null during the Cast<IFooBar>() call. Is this not working as I expect? I would think FilterCollection would be called and then myFilteredFoos would be non-null and allow for the cast. FilterCollection is not capable of returning a null which draws me to the conclusion it is not being called. Also, when I declare myFilteredFoos like this: Queryable myFilteredFoos; The Return call complains that myFilteredFoos may be used before it is initialized.

• Trying to grab just absolute links from a webpage using BeautifulSoup

  - by Kevin

  I am reading the contents of a webpage using BeautifulSoup. What I want is to just grab the <a href> that start with http://. I know in beautifulsoup you can search by the attributes. I guess I am just having a syntax issue. I would imagine it would go something like. page = urllib2.urlopen("http://www.linkpages.com") soup = BeautifulSoup(page) for link in soup.findAll('a'): if link['href'].startswith('http://'): print links But that returns: Traceback (most recent call last): File "<stdin>", line 2, in <module> File "C:\Python26\lib\BeautifulSoup.py", line 598, in __getitem__ return self._getAttrMap()[key] KeyError: 'href' Any ideas? Thanks in advance. EDIT This isn't for any site in particular. The script gets the url from the user. So internal link targets would be an issue, that's also why I only want the <'a'> from the pages. If I turn it towards www.reddit.com, it parses the beginning links and it gets to this: <a href="http://www.reddit.com/top/">top</a> <a href="http://www.reddit.com/saved/">saved</a> Traceback (most recent call last): File "<stdin>", line 2, in <module> File "C:\Python26\lib\BeautifulSoup.py", line 598, in __getitem__ return self._getAttrMap()[key] KeyError: 'href'

• Help with redirection for .com, .net and .org domains.

  - by user198553

  Hi all! I need help with some rules in ISAPI_Rewrite in my installation. I'm going to be very honest about my needs. I need to do this configuration in the next few hours, and don't have time right now understand everything about rewrites, regular expressions and such. I really think you can help me, if I had more reputation I would even set up a bounty... :( In fact, I believe that what I need is simple: I have a .com domain. The main url of my website is going to be http:// www.mainurl.com/. I have two other domains: mainurl.net and mainurl.org. What I need (in isapi-rewrite 2, the config made with httpd.ini file in root file) is: everytime someone writes mainurl.net in browser it becomes http:// www.mainurl.com/ 301 redirect. If it's written without www becomes http:// www.mainurl.com/. If someone writes mainurl.net/about it becomes http:// www.mainurl.com/about/. Redirect always the .com, the www part and the final slash /. Thanks in advance you all!

• Using Essential Use Cases to design a UI-centric Application

  - by Bruno Brant

  Hello all, I'm begging a new project (oh, how I love the fresh taste of a new project!) and we are just starting to design it. In short: The application is a UI that will enable users to model an execution flow (a Visio like drag & drop interface). So our greatest concern is usability and features that will help the users model fast and clearly the execution flow. Our established methodology makes extensive use of Use Cases in order to create a harmonious view of the application between the programmers and users. This is a business concern, really: I'd prefer to use an Agile Method with User Stories rather than User Cases, but we need to define a clear scope to sell the product to our clients. However, Use Cases have a number of flaws, most of which are related to the fact that they include technical details, like UI, etc, as can be seem here. But, since we can't use User Stories and a fully interactive design, I've decided that we compromise: I will be using Essential Use Cases in order to hide those details. Now I have another problem: it's essential (no pun intended) to have a clear description of UI interaction, so, how should I document it? In other words, how do I specify a application through the use of Essential Use Cases where the UI interaction is vital to it? I can see some alternatives: Abandon the use of Use Cases since they don't correctly represent the problem Do not include interface descriptions in the use case, but create another documentation (Story Boards) and link then to the Essential Use Cases Include UI interaction description to the Essential Use Cases, since they are part of the business rules in the perspective of the users and the application itself

• Help Converting T-SQL Query to LINQ Query

  - by campbelt

  I am new to LINQ, and so am struggle over some queries that I'm sure are pretty simple. In any case, I have been hiting my head against this for a while, but I'm stumped. Can anyone here help me convert this T-SQL query into a LINQ query? Once I see how it is done, I'm sure I'll have some question about the syntax: SELECT BlogTitle FROM Blogs b JOIN BlogComments bc ON b.BlogID = bc.BlogID WHERE b.Deleted = 0 AND b.Draft = 0 AND b.[Default] = 0 AND bc.Deleted = 0 GROUP BY BlogTitle ORDER BY MAX([bc].[Timestamp]) DESC Just to show that I have tried to solve this on my own, here is what I've come up with so far, though it doesn't compile, let alone work ... var iqueryable = from blog in db.Blogs join blogComment in db.BlogComments on blog.BlogID equals blogComment.BlogID where blog.Deleted == false && blog.Draft == false && blog.Default == false && blogComment.Deleted == false group blogComment by blog.BlogID into blogGroup orderby blogGroup.Max(blogComment => blogComment.Timestamp) select blogGroup;

• Database structure - is mySQL the right choice?

  - by Industrial

  Hi everyone, We are currently planning the database structure of a quite complex e-commerce web app that has flexibility as it's main cornerstone. Our app features a large amount of data (products) and we have run into a slight headache trying to keep performance high without compromizing normalization rules in the database, or leaving our highly beloved flexibility concept behind when integrating product options (also widely known as product attributes or parameters). Based on various references and sources available, we have made up lists on pros and cons of all major and well known database patterns to solve this. After comparing these, we have come up with two final alternatives: EAV (Entity-attribute-value model) : Pros: Database is used for all sorting. Cons: All related queries will include a number of joins between multiple tables in order to complete the collection of data. SLOB (Serialized LOB, also known as Facade?) : Pros: Very flexible. Keeping the number of necessary joins low compared to a EAV design pattern. Easy to update/add/remove data from each product. Cons: All sorting will be done by the application instead of the database. Will use lots of performance (memory?) when big datasets is processed by a large number of users. Our main questions: Which pattern/structure would you use, or maybe even a different solution? Is there better databases besides mySQL available nowadays to accomplish what we want? Thanks a lot!

• T-SQL Right Joins to ALL Entries inc Selected Column

  - by Pace

  Hi Experts, I have the following Query which produces the output below; SELECT TBLUSERS.USERID, TBLUSERS.ADusername, TBLACCESSLEVELS.ACCESSLEVELID, TBLACCESSLEVELS.AccessLevelName FROM TBLACCESSLEVELS INNER JOIN TBLACCESSRIGHTS ON TBLACCESSLEVELS.ACCESSLEVELID = TBLACCESSRIGHTS.ACCESSLEVELID INNER JOIN TBLUSERS ON TBLACCESSRIGHTS.USERID = TBLUSERS.USERID The output is this; 29 administrator 1 AllUsers 29 administrator 2 JobQueue 29 administrator 3 Telephone Directory Admin 29 administrator 4 Jobqueueadmin 29 administrator 5 UserAdmin 29 administrator 6 Product System 27 alan 1 AllUsers 97 andy 1 AllUsers 26 barry 1 AllUsers 26 barry 2 JobQueue 26 barry 3 Telephone Directory Admin 26 barry 4 Jobqueueadmin 26 barry 5 UserAdmin 26 barry 6 Product System 26 barry 7 Newseditor 26 barry 8 GreetingBoard What I would like to do is modify the query so I get all Access Levels regardless of weather there is an entry for that user. What I would also like to do is some sort of exist case so that I get output like the following; 29 administrator 1 AllUsers True 29 administrator 2 JobQueue True 29 administrator 3 Telephone Directory Admin True 29 administrator 4 Jobqueueadmin True 29 administrator 5 UserAdmin True 29 administrator 6 Product System True 29 administrator 7 Newseditor False 29 administrator 8 GreetingBoard False 27 alan 1 AllUsers True 27 alan 2 JobQueue False 27 alan 3 Telephone Directory Admin False 27 alan 4 Jobqueueadmin False 27 alan 5 UserAdmin False 27 alan 6 Product System False 27 alan 7 Newseditor False 27 alan 8 GreetingBoard False 97 andy 1 AllUsers True 97 andy 2 JobQueue False 97 andy 3 Telephone Directory Admin False 97 andy 4 Jobqueueadmin False 97 andy 5 UserAdmin False 97 andy 6 Product System False 97 andy 7 Newseditor False 97 andy 8 GreetingBoard False 26 Barry 1 AllUsers True 26 Barry 2 JobQueue True 26 Barry 3 Telephone Directory Admin True 26 Barry 4 Jobqueueadmin True 26 Barry 5 UserAdmin True 26 Barry 6 Product System True 26 Barry 7 Newseditor True 26 Barry 8 GreetingBoard True ......................................... So the rules are ALWAYS show ALL Entries for ACCESSLEVELS and where EXISTS in ACCESSRIGHTS produce a true / false to show this. I hope this makes sense and hopefully you dont need the table definitions as everything I need to work with is in the original Query. I just need a way of manipulating it slightly and getting the join in the right place. Thank you. Pace

• Advice moving from Eclipse to xCode

  - by Gloin the Dark

  To xCode xPerts: I have been doing Java in Eclipse for about 9 years now and I have really gotten used to the power of the refactoring tools. There are a few operations I do all the time. I am looking for equivalents in xCode since it has better support for objective-c than eclipse. (I'm not at my Mac as I write this. So some of this is from memory. I am still very new to xCode.) 1 "rename". It seems that the xCode equivalent for variables is "edit all in scope". Does this work for files/classes/methods too? 2 "extract local variable" select an expression it creates a local var initialized to that expression. It even creates a usable name for the variable. 3 "extract method" select some code and it will create a method with that code and appropriate parameters/return value. 4 "inline" (variable or method) opposite of extract, inlines all or just the selected occurrence of the selected var or method. 5 "find next" occurrence of selected text. In eclipse I can select some text and hit ctrl-k to go to the next occurrence of that in the file. likewise shift-ctrl-k finds backwards. IIRC the xCode "find next" ignores the selection and only uses what is in the find box. 6 "change method signature" This would be very useful with ocjective-c's named parameter messaging syntax. This is great for adding parameters to a method. 7 "pull-up/push-down" for moving methods up or down the class hierarchy. 8 "move" for moving elements around to other classes etc. Those are the ones that I use all of the time. I have estimated that these tools cut my coding time in half. Are any of these supported in xCode? Thanks in advance for any advice.

• Gallio MbUnit and Team City problem

  - by Bernard Larouche

  I asked a question this morning about an integration problem between Gallio and Team City. I changed the msbuild file to use the proper syntax with the latest Gallio build script API. Thank you for that Jeff Brown but now when I tried to build the application on Team City I get the following error : An unexpected error occurred during execution of the Gallio task.[16:19:49]: [Project "CoderForTraders.msbuild.teamcity.patch.tcprojx" (RebuildSolution;RunTests target(s)):] C:\TeamCity\buildAgent\work\fa1d38b0af329d65\CoderForTraders.msbuild(9, 9): FilterParseException: Colon expected Here's line 9 : <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)"> and here is the whole file : <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <!-- This is needed by MSBuild to locate the Gallio task --> <UsingTask AssemblyFile="C:\Gallio\bin\Gallio.MSBuildTasks.dll" TaskName="Gallio" /> <!-- Specify the test files and assemblies --> <ItemGroup> <TestFile Include="C:\_CBL\CBL\CoderForTraders\Source\trunk\UnitTest\DomainModel.Tests\bin\Debug\CBL.CoderForTraders.DomainModel.Tests.dll" /> </ItemGroup> <Target Name="RunTests"> <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)"> <!-- This tells MSBuild to store the output value of the task's ExitCode property into the project's ExitCode property --> <Output TaskParameter="ExitCode" PropertyName="ExitCode"/> </Gallio> <Error Text="Tests execution failed" Condition="'$(ExitCode)' != 0" /> </Target> <Target Name="RebuildSolution"> <Message Text="Starting to Build"/> <MSBuild Projects="CoderForTraders.sln" Properties="Configuration=Debug" Targets="Rebuild" /> </Target> </Project> Do you have an idea about the possible problem ?
