Hence it will dump all kinds of debug information, warnings, errors as well as encountered script errors. The RPT is also used by the game's engine log other type of problems (low level engine issues, or content problems for example). Scripts running on a client use the Arma X.RPT file.Scripts running on a server use the Arma XServer.RPT file which has varying location depending upon the type of server being run.Read RPT files for more information (make sure -noLogs startup parameter is not active - otherwise the log will empty).To learn about the location in your script use preprocessFileLineNumbers to preprocessFile.Be sure to use -showScriptErrors startup parameter to display the error on-screen when it happens.Aside from your script not having the desired result/effect (if any), an error message can tell you about the problem. To solve an issue, you must first to became aware that of it. This information can also be found in the RPT log. you get the error on a variable being nil somewhere, but the actual error is that you mistyped it where you set it initially). There are instances where actual error reason might be something completely different than announced (eg. You usually get hinted by the game, where some error happened, and what it was. So if you notice an issue, address it as your script will stop.ĭebugging is usually as complicated as writing the actual code itself. See further Debugging Tools page section for download links.Īn error in SQF will purely and simply halt the current script, leading to unpredictable behavior.Įrror are not to happen as it may reduce performance as well as break a mission/feature. Syntax highlight will help you find typos in commands and in your scripts.Īn Integrated Development Environment (short IDE) is a development environment software that provides among other things code analysis, code completion and syntax highlight to help you write better, more error free code. Syntax errors are a frequent occurrence when developing scripts. Various links about code and how to write it: Please check the name and try again.« Debugging is the process of finding and resolving defects or problems within a computer program that prevent correct operation of computer software or a system. » – Wikipedia ( source) In case of failure, you will see the following logs inside testlog.txt. Minimum = 82ms, Maximum = 160ms, Average = 117ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: Using ErrorLevel to detect errors and log themĮrrorlevel returns 0 if the command executes successfully and 1 if it fails.ĭuring execution, you can see errors as well as logs: Looking at the above file the developer can fix the program and execute again. More help is available by typing NET HELPMSG 3506. The file testerrors.txt will display the error messages as shown below: Let us log the message and see what we get.Įxecute the following command in your command line:Ĭ:\>test.bat > testlog.txt 2> testerrors.txt Here is an example, consider the following test.bat file: Another easy way out is to log those messages in another file and view it step by step to understand what went wrong. It might get hard to debug the error just looking at a bunch of echo displayed on the command prompt. Logging the error messages to another file In the example below, the batch script is paused as the input value is mandatory and not provided. When the script is paused, the developer can fix the issue and restart the processing. offĪnother way is to pause the batch execution when there is an error. For example, if the input given is a negative number, less than 2, etc. Similarly, the echo command can be used in place when you think that the error can happen. The echo command is used to display the result and also if the input is not given. Here is a simple example that displays even numbers based on the input given. It will display the message in the command prompt and help you debug where things have gone wrong. Using echo commandĪ very simple debug option is to make use of echo command in your batch script wherever possible. Debugging a batch script becomes important when you are working on a big complex batch script.įollowing are the ways in which you can debug the batch file.
