I'm interested: do you mainly set braikpoints to freeze your app and inspect values, or do you print values? If so, how do you process a long list of print statements?
Myself, I wrote a small "log" class to wrap the print statement. This way, I get 3 columns in the console window: time of calling (leading zeros), who called and the message. It also allows me to skip tostring() every time I print 
when I was in lua, I had a basic logger that had 4 enum states defining severity you could provide it [warning, info, error, critical] and a group identifier. you could then set a global variable to control what severity gets output and provide a wildcard string to filter based on the group identifiers.
I still have it (minus the wildcard functionality) since I moved to C, but I just use visual studio's debugger which I've really come to like.
Good tips for searching and priority filtering, thanks!
Are you working on a game that requires C performance?
yeah, you can go really far with lua on the system (IME) so I wouldnt be discouraged! I just had a pretty intensive (computationally*) game that didnt quite fit (one ex: https://twitter.com/superfunc/status/1622815423719960576?s=20)

and probably a bunch of other stuff im forgetting, which resulted in me writing my own rendering routines, memory allocation system and collision system 
Looks great! I emailed with your music designer after you tweeted about it great game type too, I bought 2 for PS5.
Looking at season 1, I think we need more action games. I’m working on a platformer, loading lots of converted Blender animations. I just can’t bring the hardware down, no matter how much I load but if you’re doing bitmap calculations, that’s another thing. I love that more and more Lua calls are very convenient and fast, like getting a faded copy of a bitmap or quickly inverting the screen.
We’ll see some very complex games in the coming years. If devs like us keep investing
definitely, would love to see people take the performance baton and push past what I've done, as well as more and more arcade & action games for the system
I use a mix of
On screen overlays is a good one too! I have a menubar that shows many numbers in debug mode, a bit like iStatMenus on Mac.
I'm interested in your mention of tostring(). I don't think I've ever used it?!
My favourite thing to do with print is the built-in tab delimited output, eg. print(a,b,c)
Ah, didn't know print accepted multiple values. So I was always joining all my values into a single string, which requires you to toString() them before you can concat
