I've written a number of these at my previous companies, which all get loaded by default when any developer was debugging (basically wrapping gdb in a 'make gdb' style call). That works for internal development at a company where everyone is using the same flow, but that's nearly impossible in the real world as every one has a different setup.
I'm assuming numerous companies have written a Linked List GDB Printer (such as https://github.com/chrisc11/debug-tips/blob/master/gdb/pytho...) or a script that prints useful information from the global variables particular to the RTOS running. These are all great, but they are a pain to install.
Is there really no better way to share these across the Internet other than "Copy / Paste this text into your .gdbinit"? I'm thinking it would be possible and relatively painless to share these scripts through PyPi, require them, and load them like a normal package, but I haven't seen this approach taken.
