• How to edit doxygen.config from shell script?

  - by Sayan Ghosh

  Hi, I tried using Apple's shell script to automate doc set creation with every build (and loading that in XCode) - http://developer.apple.com/tools/creatingdocsetswithdoxygen.html but found that it had some bugs. Firstly it's not updating the entries in doxygen.config, perhaps one needs to put the settings in the exact hierarchy as it appears in the native doxygen file (?). My intention is to specify the settings in the following fashion in the shell script, and have a suitable config file generated tailored to my needs. ... echo "DOCSET_FEEDNAME = Some app" $TEMP_DIR/doxygen.config echo "GENERATE_LATEX = NO" $TEMP_DIR/doxygen.config echo "RECURSIVE = YES" $TEMP_DIR/doxygen.config ... Thank you, Sayan

• Unix Sockets in Go

  - by marketer

  I'm trying to make a simple echo client and server that uses Unix sockets. In this example, the server can receive data from the client, but it can't send the data back. If I use tcp connections instead, it works great: Server package main import "net" import "fmt" func echoServer(c net.Conn) { for { buf := make([]byte, 512) nr, err := c.Read(buf) if err != nil { return } data := buf[0:nr] fmt.Printf("Received: %v", string(data)) _, err = c.Write(data) if err != nil { panic("Write: " + err.String()) } } } func main() { l, err := net.Listen("unix", "/tmp/echo.sock") if err != nil { println("listen error", err.String()) return } for { fd, err := l.Accept() if err != nil { println("accept error", err.String()) return } go echoServer(fd) } } Client package main import "net" import "time" func main() { c,err := net.Dial("unix","", "/tmp/echo.sock") if err != nil { panic(err.String()) } for { _,err := c.Write([]byte("hi\n")) if err != nil { println(err.String()) } time.Sleep(1e9) } }

• WCF REST Does Not Contain All of the Relative File Path

  - by Brandon

  I have a RESTful WCF 3.5 endpoint as such: System.Security.User.svc This is supposed to represent the namespace of the User class and is desired behavior by our client. I have another endpoint I created for testing called: Echo.svc I am writing an overridden IHttpModule and in my module, I follow what almost everyone does by doing: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If I make a call to: http://localhost/services/Echo/test My path variable has a value of '~/echo/test' However, when I make a call to: http://localhost/services/System.Security.User/test My path variable has a value of '~/system.security.user' In my 2nd situation, it is stripping off the '/test' on the end of any endpoint that contains multiple periods. This is undesired behavior and the only solution I have found to fixing this is some ugly string manipulation using the property which does contain the complete URL path: string rawPath = HttpContext.Current.Request.RawUrl; This returns '/services/system.security.user/test'. Does anyone know why my first situation does not return the rest of the URL path for endpoints that contain multiple periods in the name?

• Batch file writing to log then ending process

  - by Andrew Service

  I have a batch file that calls a process and in that process I have: IF %ERRORLEVEL% NEQ 0 EXIT /B %ERRORLEVEL% Now I wanted to upgrade this a bit and give some meaningful message to an output log when if the process fails, also I do not want the main batch to continue processing because the next processes are dependent on data from previous calls; I wonder if this would be correct but not sure: CALL Process 1 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInfirstProcess /B %ERRORLEVEL% :ErrorInfirstProcess ECHO Process 1 Failed on %Date% at %Time%. >>C:\Log.txt" CALL Process 2 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInSecondProcess /B %ERRORLEVEL% :ErrorInSecondProcess ECHO Process 2 Failed on %Date% at %Time%. >>C:\Log.txt" I also want to know if I still need the /B or do I need to put an EXIT command after the echo? Thanks A

• PHP exec not working with gcc

  - by teehoo

  I just spent a few hours pulling my hair out over this. I'm trying to get gcc to compile a file from within PHP. $command = "/usr/bin/gcc /var/www/progpad/temp/tNu7rq.c -o /var/www/progpad/temp/tNu7rq.out"; exec($command, $output, $returnVal); echo $returnVal."<br />"; //returns 1 echo json_encode($output); //returns [] I'm running this on my own ubuntu server and both /var/www/progpad/ /var/www/progpad/temp/ have chmod 777 set. If I copy and paste the command string, and paste it into the terminal it works perfectly. Also if I replace the command string with something like $command = "echo test > test.txt"; Then this has no problem creating the text file. What could I possibly be doing wrong here???

• How to properly match the following message id format in a case statement

  - by hsatterwhite

  I'm trying to get this regex pattern working in a case statement to match a particular type of ID, which could be passed to the script. I need to match the exact number of alphanumeric characters with the dashes to differentiate this message id from anything else, which may be passed to this bash script. An example of the message id format: c7c3e910-c9d2-71e1-0999-0aec446b0000 #!/bin/bash until [ -z "$1" ] do case "$1" in "") echo "No value passed" ;; [a-z0-9]\{8\}-[a-z0-9]\{4\}-[a-z0-9]\{4\}-[a-z0-9]\{4\}-[a-z0-9]\{12\}) echo "Found message ID: $1" ;; *) echo "Server $1" ;; esac shift done

• Unix - "xargs" - output "in the middle" (not at the end!)

  - by Petike

  Hello, example use of "xargs" application in Unix can be something like this: ls | xargs echo which is the same as (let's say I have "someFile" and "someDir/" in the working dir): echo someFile someDir so "xargs" take its "input" and place it "at the end" of the next command (here at the end of echo). But sometimes I want xargs to place its input somewhere "in the middle" of next command. For example: find . -type f -name "*.cpp" -print | xargs g++ -o outputFile so if I had in the current directory files "a.cpp" "b.cpp" "c.cpp" the output would be the same as with the command: g++ -o outputFile a.cpp b.cpp c.cpp but I want to have something like this: g++ a.cpp b.cpp c.cpp -o outputFile Is there a way to do it? P.S.: I need it in some cases, because e.g.: i586-mingw32msvc-g++ -o outputFile `pkg-config --cflags --libs gtkmm-2.4` a.cpp b.cpp c.cpp doesn't work but this one works fine: i586-mingw32msvc-g++ a.cpp b.cpp c.cpp -o outputFile `pkg-config --cflags --libs gtkmm-2.4` Thanks.

• Cookie Value not available, why?

  - by Camran

  I have tested this on my development computer, but now I have uploaded everything to the production server and I cant read out the value of the cookie. I think the problem lies in the Serialization and Unserialization. if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; //20 days $ad_arr = unserialize($_COOKIE['watched_ads']); // HERE IS THE PROBLEM $arr_elem = count($ad_arr); if (in_array($ad_id, $ad_arr) == FALSE){ if ($arr_elem>10){ array_shift($ad_arr); } $ad_arr[]=$ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } When I echo this: count($ad_arr) I receive the expected nr, 1 in this case, so there is a value there. But when I echo the value: echo $ad_arr[0]; I get nothing. Completely blank. No text at all. Anybody have a clue? if you need more info about something let me know...

  Say I have this html: <a href="http://example.com">Test</a> I parse it using dom document with this code: $dom = new DomDocument(); @$dom->loadHTML($html); $urls = $dom->getElementsByTagName('a'); And then I run this code: foreach ($urls as $url) { //echo "<br> {$url->getAttribute('href')} , {$url->getAttribute('title')}"; foreach ($url->attributes as $a) { echo "<br>$a->name is $a->value"; } echo "<hr><br>"; } When I do this, I only see 'href' as an attribute of the url, there's no way to get the 'anchor text' (in the above case 'Test'). How can I get the anchor text of the link?

• insert VBS variable within a single-quoted WMI query

• How to run shell script with live feedback from PHP?

  - by Highway of Life

  How would I execute a shell script from PHP while giving constant/live feedback to the browser? I understand from the system function documentation: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. I'm not clear on what they mean by running it as a 'server module'. I attempted to run the script in the cgi-bin, but either I'm doing it wrong, or that's not what they mean. Example PHP code: <?php system('/var/lib/script_test.sh'); Example shell code: #!/bin/bash echo "Start..." for i in {1..10} do echo "$i..." sleep 1 done echo "Done."

• Passing CMD Results to Variable in a Batch File

  - by TripleNad

  I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.
