• How to deal with clients and iterations in Agile team?

  - by Ondrej Slinták

  This thread is a follow up to my previous one. It's in fact 2 questions, so I hope no one minds, as they are dependent on each other. We are starting a new project at work and we consider it as a great opportunity to try Agile techniques in action. We had a brainstorming about ideas we read in several books and articles, and came up with concept that would suit us the best: 2 weeks iteration, followed by call with clients who would choose what stuff they want to have in next iteration. I just have few more questions, which we couldn't figure out ourselves. What to do in the first iteration? What to, generally, do in the first few iterations if we start from the scratch? Just give it a month of development to code core of the application or start with simple wire-frames with limited pre-coded functionality? What usually clients want to see? Shiny stuff that doesn't work or ugly stuff that does work? How to communicate with clients? Our initial thought it to set the process to something like this: Is it a good idea to have a Focal Point on client side or is it better to communicate straight with all the clients to prevent miscommunication? Any thoughts are welcome! Thanks in advance.

• Another rsAccessDenied problem with SSRS

  - by Rich.Carpenter

  I've read through a lot of posts regarding the problem, but none of the proposed solutions have worked for me. I continue to get an error stating, "The permissions granted to user '\Rich' are insufficient for performing this operation. (rsAccessDenied)." If I am logged in as the local administrator account, entering the Reporting Services URL in IE doesn't give me that error, but it takes me to a blank page. I haven't been able to get to a SSRS home page at all. Order of operations: I installed and patched Windows 7 Ultimate 64-bit I installed SQL Server Express 2008 with Advanced Services using the MS web installer. I downloaded and installed SP1 for SQL Server Express 2008. I've tried running IE as administrator, adding local machine to trusted sites, and just about every other suggestion I've found. I even ran the entire installation logged in as the local administrator. Nothing seems to work. Could someone please tell me, considering the above installation process, what I should expect to do after to make this work?

• Text piped to PowerShell.exe isn't recieved when using [Console]::ReadLine()

  - by crtracy

  I'm getting itermittent data loss when calling .NET [Console]::ReadLine() to read piped input to PowerShell.exe: >ping localhost | powershell -NonInteractive -NoProfile -C "do {$line = [Console]::ReadLine(); ('' + (Get-Date -f 'HH:mm :ss') + $line) | Write-Host; } while ($line -ne $null)" 23:56:45time<1ms 23:56:45 23:56:46time<1ms 23:56:46 23:56:47time<1ms 23:56:47 23:56:47 Normally 'ping localhost' from Vista64 looks like this, so there is a lot of data missing from the output above: Pinging WORLNTEC02.bnysecurities.corp.local [::1] from ::1 with 32 bytes of data: Reply from ::1: time<1ms Reply from ::1: time<1ms Reply from ::1: time<1ms Reply from ::1: time<1ms Ping statistics for ::1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms But using the same API from C# recieves all the data sent to the process (excluding some newline differences). Code: namespace ConOutTime { class Program { static void Main (string[] args) { string s; while ((s = Console.ReadLine ()) != null) { if (s.Length > 0) // don't write time for empty lines Console.WriteLine("{0:HH:mm:ss} {1}", DateTime.Now, s); } } } } Output: 00:44:30 Pinging WORLNTEC02.bnysecurities.corp.local [::1] from ::1 with 32 bytes of data: 00:44:30 Reply from ::1: time<1ms 00:44:31 Reply from ::1: time<1ms 00:44:32 Reply from ::1: time<1ms 00:44:33 Reply from ::1: time<1ms 00:44:33 Ping statistics for ::1: 00:44:33 Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), 00:44:33 Approximate round trip times in milli-seconds: 00:44:33 Minimum = 0ms, Maximum = 0ms, Average = 0ms So, if calling the same API from PowerShell instead of C# many parts of StdIn get 'eaten'. Is the PowerShell host reading string from StdIn even though I didn't use 'PowerShell.exe -Command -'?

• Advice on using .Net WorkFlow State Machine. What would you do?

  - by jlafay

  So I've been tasked at work to write windows services to replace some old legacy VB6 WinForms apps currently running as services, consistently repeating tasks day-to-day. To give some general background, they have there own state machines built in to handle decision basing and not utilizing threading. A lot of the senior developers here thought it would be worth a try to look into WorkFlow to replace the state machines rather than write my own business logic and try threading it programmaticly. So it's WF vs. the "Old College Try" I suppose. My concern is that there aren't many books on the topic, and since it was implemented in .Net I've heard very little about it being used. I brought this up at work and another developer mentioned that it's because Biz Talk never really caught on and it was designed for that. So is it broken? Do you think it will be supported long enough to not worry so much? I don't want an ill-functioning process injected into my services, my new babies at work, and then have WF's keel over. Leaving me with having to replace them with my own code in the event of an emergency; which does not seem like much of a grand scenario to me. Any suggestions, recommendations would be super.

• Why are my event listeners firing more than once?

  - by Arms

  In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each. frame 1 - Landing frame 2 - Game The flow of the application is simple: User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1 Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here. I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem. I need to ensure that the event listeners only fire once. Any advice & insight would be greatly appreciated, thanks!

• How to use Grails Spring Security Plugin to require logging in before access an action?

  - by Hoàng Long

  Hi all, I know that I can use annotation or Request mapping to restrict access to an ACTION by some specific ROLES. But now I have a different circumstance. My scenario is: every user of my site can create posts, and they can make their own post public, private, or only share to some other users. I implement sharing post by a database table PERMISSION, which specify if a user have the right to view a post or not. The problem arises here is that when a customer access a post through a direct link, how can I determine he/she have the privilege to view it? There's 3 circumstances: The post is public, so it can be viewed by anyone (include not-login user) The post is private, so only the login-owner can view it The post is sharing, it means only the login-user that is shared and the owner can view it. I want to process like this: If the requested post is public: ok. If the requested post is private/sharing: I want to redirect the customer to the login page; after logging in, the user will be re-direct to the page he wants to see. The problem here is that I can redirect the user to login controller/ auth action, but after that I don't know how to redirect it back. The link to every post is different by post_id, so I can't use SpringSecurityUtils.securityConfig.successHandler.defaultTargetUrl Could anyone know a way to do this?

• Sweave can't see a vector if run from a function ?

  - by PaulHurleyuk

  I have a function that sets a vector to a string, copies a Sweave document with a new name and then runs that Sweave. Inside the Sweave document I want to use the vector I set in the function, but it doesn't seem to see it. (Edit: I changed this function to use tempdir(() as suggested by Dirk) I created a sweave file test_sweave.rnw; % \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{Sweave} \begin{document} \title{Test Sweave Document} \author{gb02413} \maketitle <<>>= ls() Sys.time() print(paste("The chosen study was ",chstud,sep="")) @ \end{document} and I have this function; onOK <- function(){ chstud<-"test" message(paste("Chosen Study is ",chstud,sep="")) newfile<-paste(chstud,"_report",sep="") mypath<-paste(tempdir(),"\\",sep="") setwd(mypath) message(paste("Copying test_sweave.Rnw to ",paste(mypath,newfile,".Rnw",sep=""),sep="")) file.copy("c:\\local\\test_sweave.Rnw", paste(mypath,newfile,".Rnw",sep=""), overwrite=TRUE) Sweave(paste(mypath,newfile,".Rnw",sep="")) require(tools) texi2dvi(file = paste(mypath,newfile,".tex",sep=""), pdf = TRUE) } If I run the code from the function directly, the resulting file has this output for ls(); > ls() [1] "chstud" "mypath" "newfile" "onOK" However If I call onOK() I get this output; > ls() [1] "onOK" and the print(...chstud...)) function generates an error. I suspect this is an environment problem, but I assumed because the call to Sweave occurs within the onOK function, it would be in the same enviroment, and would see all the objects created within the function. How can I get the Sweave process to see the chstud vector ? Thanks Paul.

• Nose2 multiprocess error on Windows7

  - by tt293

  I was looking into nose2 as a way to get around the restrictions of having both xunit output and multiprocessing in nose1.3. However, when always-on is set to False in the [multiprocess] section, I can only get a single process running, while when running with always-on set to True, I get the following error: ---------------------------------------------------------------------- Ran 0 tests in 0.043s OK Traceback (most recent call last): File "C:\dev\testing\Tests\PythonTests\venv\Scripts\nose2-script.py", line 8, in <module> load_entry_point('nose2==0.4.7', 'console_scripts', 'nose2')() File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 284, in discover return main(*args, **kwargs) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 98, in __init__ super(PluggableTestProgram, self).__init__(**kw) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\unittest2-0.5.1- py2.7.egg\unittest2\main.py", line 98, in __init__ self.runTests() File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 260, in runTests self.result = runner.run(self.test) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\runner.py", line 53, in run executor(test, result) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\plugins\mp.py", line 60, in _runmp ready, _, _ = select.select(rdrs, [], [], self.testRunTimeout) select.error: (10038, 'An operation was attempted on something that is not a soc ket') This is running python 2.7.5 (32bit) on Windows 7 in a virtualenv with six-1.1.0, unittest2-0.5.1 and nose2-0.4.7 (I get the same behavior outside of the venv, so I don't think that is the issue here).

• Where should I store shared resources between LocalSystem and regular user with UAC?

  - by rwired

  My application consists of two parts: A Windows Service running under the LocalSystem account and a client process running under the currently logged in regular user. I need to deploy the application across Windows versions from XP up to Win7. The client will retrieve files from the web and collect user data from the user. The service will construct files and data of it's own which the client needs to read. I'm trying to figure out the best place (registry or filesystem, or mix) to store all this. One file the client or service needs to be able to retrieve from the net is an update_patch executable which needs to run whenever an upgrade is available. I need to be sure the initial installer SETUP.EXE, and also the update_patch can figure out this ideal location and set a RegKey to be read later by both client and server telling them the magic location (The SETUP.EXE will run with elevated privileges since it needs to install the service) On my Win7 test system the service %APPDATA% points to: C:\Windows\system32\config\systemprofile\AppData\Roaming and the %APPDATA% of the client points to: C:\Users\(username)\AppData\Roaming Interestingly Google Chrome stores everything (App and Data) in C:\Users\(username)\AppData\Local\Google\Chrome Chrome runs pretty much in exactly the way I want my suite to run (able to silently update itself in the background) What I'm trying to avoid is nasty popups warning the user that the app wants to modify the system, and I want to avoid problems when VirtualStore doesn't exist because the user is running XP/2000/2003 or has UAC turned off. My target audience are non-tech-savvy general Windows users.

• What is the fastest way for reading huge files in Delphi?

  - by dummzeuch

  My program needs to read chunks from a huge binary file with random access. I have got a list of offsets and lengths which may have several thousand entries. The user selects an entry and the program seeks to the offset and reads length bytes. The program internally uses a TMemoryStream to store and process the chunks read from the file. Reading the data is done via a TFileStream like this: FileStream.Position := Offset; MemoryStream.CopyFrom(FileStream, Size); This works fine but unfortunately it becomes increasingly slower as the files get larger. The file size starts at a few megabytes but frequently reaches several tens of gigabytes. The chunks read are around 100 kbytes in size. The file's content is only read by my program. It is the only program accessing the file at the time. Also the files are stored locally so this is not a network issue. I am using Delphi 2007 on a Windows XP box. What can I do to speed up this file access?

• visualising piano performance evaluation

  - by Dolphin

  I need to develop a performance evaluator for piano playing. Based on a midi generated from sheet music, I need to evaluate the midi of the actual playing (midi keyboard). I'm planning to evaluate the playing based on note pitch, duration and loudness. The evaluation is I suppose a comparison of the notes of the sheet music and playing in midi. But I have no idea how I can visualise (i.e. show where the person have gone wrong) this evaluation process. i.e. maybe show both the notation and highlight which note has gone wrong. But how can I show any of this in some graphical form? Or more precisely on a stave (a music score) itself. I have note details (pitch, duration) and score details (key and time signature) stored in a table, and I'm using Java. But I have no clue as in how I can put all this into graphical form. Any insight is most gratefully appreciated. Advance thanks

• Why two subprocesses created by Java behave differently?

  - by Lily

  I use Java Runtime.getRuntime().exec(command) to create a subprocess and print its pid as follows: public static void main(String[] args) { Process p2; try { p2 = Runtime.getRuntime().exec(cmd); Field f2 = p2.getClass().getDeclaredField("pid"); f2.setAccessible(true); System.out.println( f2.get( p2 ) ); } catch (Exception ie) { System.out.println("Yikes, you are not supposed to be here"); } } I tried both C++ executable and Java executable (.jar file). Both executables will continuously print out "Hello World" to stdout. When cmd is the C++ executable, the pid is printed out to console but the subprocess gets killed as soon as main() returns. However, when I call the .jar executable in cmd, the subprocess does not get killed, which is the desired behavior. I don't understand why same Java code, with different executables can behave so differently. How should I modify my code so that I could have persistent subprocesses in Java. Newbie in this field. Any suggestion is welcomed. Lily

• How to: Simulating keystroke inputs in shell to an app running in an embedded target

  - by fzkl

  I am writing an automation script that runs on an embedded linux target. A part of the script involves running an app on the target and obtaining some data from the stdout. Stdout here is the ssh terminal connection I have to the target. However, this data is available on the stdout only if certain keys are pressed and the key press has to be done on the keyboard connected to the embedded target and not on the host system from which I have ssh'd into the target. Is there any way to simulate this? Edit: Elaborating on what I need - I have an OpenGL app that I run on the embedded linux (works like regular linux) target. This displays some graphics on the embedded system's display device. Pressing f on the keyboard connected to the target outputs the fps data onto the ssh terminal from which I control the target. Since I am automating the process of running this OpenGL app and obtaining the fps scores, I can't expect a keyboard to be connected to the target let alone expect a user to input a keystroke on the embedded target keyboard. How do I go about this? Thanks.

• Push TFS 2008 code to remote VSS over VPN?

  - by drovani

  We have a local Team Foundation Server 2008 that we keep our code under version control. However, we also have a paranoid client that has their own Visual Source Safe installation that wants us to keep a running copy of the code on their server as well. As such, I'm hoping there is a way I can just do a nightly push from our TFS repository to their VSS repository. I'm not concerned about keeping each changeset on TFS as a different changeset on the VSS, just a once-nightly push that creates a new changeset on the VSS and uploads the latest changeset from TFS. I guess the first part is if it is even possible for TFS to push an update to VSS. I've noticed that most replies to this question have been something to the tune of "don't do it", but I can't find anything that specifically states that it cannot be done. The second part would then be automating the process by having the TFS server connect to the client's VPN, then push the code changes. I have full control over the TFS server and I can customize the VSS install, if there are settings that need changing, but I'm limited on what I can do about settings on either firewall or server specific settings on the client's VSS server.

• How to inherit the current path when invoking Maven's exec-maven-plugin?

  - by wishihadabettername

  I have an <exec-maven-plugin> which calls an external command (in this case, svnversion). The command is in the path for the current user. However, when a separate shell is spawned by the plugin, the path is not initialized. I don't want to hardcode or define a variable for each external command (there would be too much to maintain, especially that there are both Windows and *nix users). My pom.xml contains the following: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1</version> <executions> <execution> <id>svnversion-exec</id> <phase>process-resources</phase> <goals> <goal>exec</goal> </goals> <configuration> <executable>svnversion</executable> <arguments> <argument><![CDATA[ >version.txt ]]></argument> </arguments> </configuration> </execution> </executions> </plugin> Currently I get the following output: [INFO] [exec:exec {execution: svnversion-exec}] 'svnversion' is not recognized as an internal or external command, operable program or batch file. [ERROR] BUILD ERROR: Result of cmd.exe /X /C "svnversion >version.txt" execution is: '1'. Thank you!

• select failing with C program but not shell

  - by Gary

  So I have a parent and child process, and the parent can read output from the child and send to the input of the child. So far, everything has been working fine with shell scripts, testing commands which input and output data. I just tested with a simple C program and couldn't get it to work. Here's the C program: #include <stdio.h> int main( void ) { char stuff[80]; printf("Enter some stuff:\n"); scanf("%s", stuff); return 0; } The problem with with the C program is that my select fails to read from the child fd and hence the program cannot finish. Here's the bit that does the select.. //wait till child is ready fd_set set; struct timeval timeout; FD_ZERO( &set ); // initialize fd set FD_SET( PARENT_READ, &set ); // add child in to set timeout.tv_sec = 3; timeout.tv_usec = 0; int r = select(FD_SETSIZE, &set, NULL, NULL, &timeout); if( r < 1 ) { // we didn't get any input exit(1); } Does anyone have any idea why this would happen with the C program and not a shell one? Thanks!

• Stack Overflow problem transforming with a custom xslt

  - by Flynn1179

  I've got a system that allows the user the option of providing their own XSLT to apply to some data that's been retrieved, as a means of specifying how that data should be presented. However, if the user includes code in the XSLT equivalent to: <xsl:template match="/"> <xsl:element name="data"> <xsl:apply-templates select="." /> </xsl:element> </xsl:template> this causes .NET to infinitely recurse trying to process it, and produces a stack overflow error. I need to be able to trap this before it crashes the app, as the data that's been retrieved is occasionally quite time-consuming to obtain, and the data is lost when this happens. Is there any way of doing this? I know it's theoretically possible to identify any occurrences of xsl:apply-templates with "." in the select attribute, but this isn't the only way an infinite recursion could happen, I need a way of generically trapping it.

• Silverlight Socket Constantly Returns With Empty Buffer

  - by Benny

  I am using Silverlight to interact with a proxy application that I have developed but, without the proxy sending a message to the Silverlight application, it executes the receive completed handler with an empty buffer ('\0's). Is there something I'm doing wrong? It is causing a major memory leak. this._rawBuffer = new Byte[this.BUFFER_SIZE]; SocketAsyncEventArgs receiveArgs = new SocketAsyncEventArgs(); receiveArgs.SetBuffer(_rawBuffer, 0, _rawBuffer.Length); receiveArgs.Completed += new EventHandler<SocketAsyncEventArgs>(ReceiveComplete); this._client.ReceiveAsync(receiveArgs); if (args.SocketError == SocketError.Success && args.LastOperation == SocketAsyncOperation.Receive) { // Read the current bytes from the stream buffer int bytesRecieved = this._client.ReceiveBufferSize; // If there are bytes to process else the connection is lost if (bytesRecieved > 0) { try { //Find out what we just received string messagePart = UTF8Encoding.UTF8.GetString(_rawBuffer, 0, _rawBuffer.GetLength(0)); //Take out any trailing empty characters from the message messagePart = messagePart.Replace('\0'.ToString(), ""); //Concatenate our current message with any leftovers from previous receipts string fullMessage = _theRest + messagePart; int seperator; //While the index of the seperator (LINE_END defined & initiated as private member) while ((seperator = fullMessage.IndexOf((char)Messages.MessageSeperator.Terminator)) > 0) { //Pull out the first message available (up to the seperator index string message = fullMessage.Substring(0, seperator); //Queue up our new message _messageQueue.Enqueue(message); //Take out our line end character fullMessage = fullMessage.Remove(0, seperator + 1); } //Save whatever was NOT a full message to the private variable used to store the rest _theRest = fullMessage; //Empty the queue of messages if there are any while (this._messageQueue.Count > 0) { ... } } catch (Exception e) { throw e; } // Wait for a new message if (this._isClosing != true) Receive(); } } Thanks in advance.

• getting a "default" concrete class that implements an interface

  - by Roger Joys

  I am implementing a custom (and generic) Json.net serializer and hit a bump in the road that I could use some help on. When the deserializer is mapping to a property that is an interface, how can I best determine what sort of object to construct to deserialize to to place into the interface property. I have the following: [JsonConverter(typeof(MyCustomSerializer<foo>))] class foo { int Int1 { get; set; } IList<string> StringList {get; set; } } My serializer properly serializes this object, and but when it comes back in, and I try to map the json parts to to object, I have a JArray and an interface. I am currently instantiating anything enumerable like List as theList = Activator.CreateInstance(property.PropertyType); This works create to work with in the deserialization process, but when the property is IList, I get runtime complaints (obviously) about not being able to instantiate an interface. So how would I know what type of concrete class to create in a case like this? Thank you

• Delaying LINQ to SQL Select Query Execution

  - by Maxim Z.

  I'm building an ASP.NET MVC site that uses LINQ to SQL. In my search method that has some required and some optional parameters, I want to build a LINQ query while testing for the existence of those optional parameters. Here's what I'm currently thinking: using(var db = new DBDataContext()) { IQueryable<Listing> query = null; //Handle required parameter query = db.Listings.Where(l => l.Lat >= form.bounds.extent1.latitude && l.Lat <= form.bounds.extent2.latitude); //Handle optional parameter if (numStars != null) query = query.Where(l => l.Stars == (int)numStars); //Other parameters... //Execute query (does this happen here?) var result = query.ToList(); //Process query... Will this implementation "bundle" the where clauses and then execute the bundled query? If not, how should I implement this feature? Also, is there anything else that I can improve? Thanks in advance.

• Multi-threaded library calls in ASP.NET page request.

  - by ProfK

  I have an ASP.NET app, very basic, but right now too much code to post if we're lucky and I don't have to. We have a class called ReportGenerator. On a button click, method GenerateReports is called. It makes an async call to InternalGenerateReports using ThreadPool.QueueUserWorkItem and returns, ending the ASP.NET response. It doesn't provide any completion callback or anything. InternalGenerateReports creates and maintains five threads in the threadpool, one report per thread, also using QueueUserWorkItem, by 'creating' five threads, also with and waiting until calls on all of them complete, in a loop. Each thread uses an ASP.NET ReportViewer control to render a report to HTML. That is, for 200 reports, InternalGenerateReports should create 5 threads 40 times. As threads complete, report data is queued, and when all five have completed, report data is flushed to disk. My biggest problems are that after running for just one report, the aspnet process is 'hung', and also that at around 200 reports, the app just hangs. I just simplified this code to run in a single thread, and this works fine. Before we get into details like my code, is there anything obvious in the above scendario that might be wrong?

• How to install previously-archived apps from xcode organizer to my iphone

  - by Ben Clayton

  Hi all. Xcode keeps an archive of all the versions of my apps that I've submitted to the app store in the 'archived applications' section. I assumed using this I could install an old version of an app to my device, in order to reproduce any problems my client may have had with that particular version. However, when I try to do this I get an error: 'this executable was signed with invalid entitlements, the entitlements specified in your applications code signing entitlements do not match those specified in your provisioning profile' The original app was signed using our App Store distribution certificate, and I use the Organizer interface to re-sign it using our Developer profile. select the archived app select the version I want to test click 'share' select 'iphone developer' next to identity save to disk (saves the ipa file) then copy the ipa to the device using the little + button you see next to 'applications' on the screen you get when you select the connected device. Then I get the error, and the app isn't installed. Is there something obvious I'm doing wrong here? Or is there a different process to re-install an archived app to my device? Thanks,

• Spawning vim from a node git hook

  - by Lawrence Jones

  I've got a project purely in coffeescript, with git hooks for deployment also written in cs. I don't really want to break away from the language just to use bash for a quick commit message formatter, but I've got a problem spawning vim from the commit-msg hook. I've seen here that when piping to vim, the stdio is not necessarily set correctly to the tty streams. I get how that could cause a problem, but I don't exactly know how to get vim to load correctly using nodes spawn command. At the moment I have... vim = (require 'child_process').spawn('vim', [file], stdio: 'inherit') vim.on 'exit', (err) -> console.log "Exited! [#{err}]" cb?() ...which works fine to spawn a vim process that can r/w from the parents stdio, but when I use this in the hook things go wrong. Vim states that the stdio is not from terminal, and then once opened typing causes escape characters to pop up all over the place. Backspace for example, will produce ^?. Any help would be appreciated!
