Here are some commands that can help you get more information is you have problems when a connection has already been established (e.g. Problems here are generally due to configuration rather than OpenSimulator code issues. This trips people up a lot because of the complex interplay between different server processes in grid mode and between simulator and viewer, with viewers on both the local LAN and over the Internet. This section will be expanded as time goes on. However, there are a few things we say about debugging specific OpenSimulator issues. Unfortunately, due to Mono limitations can only work on the current thread. ![]() Util.PrintCallStack() - This will print the call stack at the time the method is executed before continuing execution.There are also some internal methods that might be useful. Generally these can be uncommented to provide extra useful information, though you may have to resort to adding new log statements. There are also logging statements through the OpenSimulator code, some of which are commented out. If someone knows would be great to get this section filled in. Not sure how to achieve the same result on Windows, if this is possible at all. If you do this, you are advised to restart the process in question after all useful debugging information has been captured. Sending SIGQUIT to Mono may make it unstable. This is sometimes the only way to pin down which parts of the code threads may be deadlocked on. If at all possible, please start Mono with the -debug switch so that line numbers are added to traces (there is no major performance penalty on using this switch). If you are reported this trace for debug purposes, it is essential that it is captured and reported accurately. You can do this either with CTRL \ on the console or by a command such as In Mono, you can get this dump by sending the SIGQUIT unix signal to the Mono process. In this case, a dump of all threads can provide useful information. If the simulator or some aspect of it appears to be frozen, one possibility is that threads are in deadlock for some reason. However, one thing to note is that the debugger must be capable of ignoring the SelfDeleteException - this is currently used by the XEngine script engine to kill scripts aborted via the llDie() LSL command. We won't go through general information about using debuggers here, you can find it elsewhere on the net. In general, OpenSimulator is a difficult system to debug due to its high concurrency, complexity and the lack of good tools for Mono on the Linux/Mac side. 4.2 Problems after connection established.I am open to suggestions, GitHub Issues and Pull Requests or anything else that you may want to contribute.

The Firestorm Preprocessor is a very helpful to me and since LSLint has support for it. There are a lot of upsides to working on your LSL files in VSCode as you always have a backup should you need.

Any contributions or fixes are always welcome as Pull Requests. I am not a professional TypeScript/NodeJS programmer and this is the first thing I have ever written in it. You will need an external extension for LSL Syntax Highlighting or else the extension will not activate!.This will depend on your operating system and instructions for that will be on your favorite search engine. You must add the folder containing LSLint to your path.Visit the LSLint releases page to download it for your system. ![]() ![]() You must download and install the LSLint executable yourself as this extension is just a wrapper for it!.Check it out here Required Extra Installs I have updated the LSLint executable to the current LSL calls as of July 2021. ![]() If you are looking for a way to write LSL scripts from VSCode then this extension should help you a lot! Wrapper for LSLint LSL being a scripting language for the virtual world of Second Life.
