Hello, Ladies and Gentlemen, I am back in the game and want to ask some questions regarding debugging support: What are your current pain points with debugging support? Is anyone using VS Code with CodeLLDB for debugging, or do you prefer some other IDEs for Crystal? I am trying to plan my time …

I pretty much use Emacs exclusively for an IDE, and would prefer to use GDB from the command line for a debugger instead of LLDB. But tbh, 95% of the time I just use puts and pp. The biggest issue I run into while debugging is build times vs a binary that’s actually performant enough to use.

Debug: I debug in GDB directly (Linux). I also tried WinDBG on Windows to debug a segfault, and it just worked. I heard that the integration with the vscode debugger doesn’t work (but maybe you need a plugin). That being said the GDB command line is very powerful but the DX ain’t intuitive (must le…

I used to use vi on the remote shells, but for the last twenty years, I have rarely used it. I use Midnight Commander most of the time, and mcedit is my main editor. When I started working on Crystal debugging support, I used a lot of logging. It generated nearly a gigabyte of logs and was nearly …

I use macOS, so gdb does not work there (it hangs OS badly, so you will have to reboot :frowning: ), so lldb works like a charm. lldb supplied with macOS does not have Python scripting enabled by default, so you must build your version with enabled Python support. After that, my scripts started sh…

Is there a tutorial somewhere about setting up lldb with those scripts? I have been somewhat frustrated by the debugging experience (as in: I can’t debug much)

Ok, I debug with pp, but if normal debugging would be possible it would be great. I tried to use CodeLLDB on Windows: thread ‘main’ panicked at ‘called Result::unwrap() on an Err value: “Could not load "c:\\Users\\\username\\.vscode\\extensions\\vadimcn.vscode-lldb-1.10.0\\lldb\\bin\\liblldb.dll" …

BTW, i followed this post, and tested on a lucky project recently. it works on my arch linux with lldb/llvm 18.1.18, crystal 1.13.2, codelldb plugin version 1.10.0 on code 1.93.1 Following is screenshot. [image] .vscode/launch.json { "version": "0.2.0", "configurations": [ { …

I will try to find some time to play with Crystal::Tracing, so it can be quite interesting.

I didn’t have a chance to check it on Windows as I stopped using it about ten years ago, so I am mostly a Mac guy these days. I hope that someone was able to reproduce it. If not, then I will try то find my old license with Windows 11 and install it on VM.
