Regular expressions for Python built-in types

bool_pattern = ".*"
int_pattern = r"[+-]?(?:[0-9]|[0-9][0-9_]*[0-9])"
float_numeric_pattern = r"[+-]?(?:[0-9]\.?|[0-9][0-9_]*[0-9]\.?|(?:[0-9]|[0-9][0-9_]*[0-9])?\.(?:[0-9]|[0-9][0-9_]*[0-9]))(?:[eE][+-](?:[0-9]|[0-9][0-9_]*[0-9]))?"
float_pattern = r"[+-]?(?:(?:[0-9]\.?|[0-9][0-9_]*[0-9]\.?|(?:[0-9]|[0-9][0-9_]*[0-9])?\.(?:[0-9]|[0-9][0-9_]*[0-9]))(?:[eE][+-](?:[0-9]|[0-9][0-9_]*[0-9]))?|[iI][nN][fF](?:[iI][nN][iI][tT][yY])?|[nN][aA][nN])"

Expanded

Useful when using python -c 'python_script' as part of a larger task/shell script.

These one-liners will exit with exit code 1 if "no" is chosen.

Reprompt for invalid inputs

paper-versions.json

JSON containing links to the all known PaperMC versions.

Note

This JSON is being updated manually. If you want to always have the most actual paper-versions.json, check out this generator: qing762/paper-version-links (dynamic JSON)

Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

Debug with GDB on macOS 11

The big reason to do this is that LLDB has no ability to "follow-fork-mode child", in other words, a multi-process target that doesn't have a single-process mode (or, a bug that only manifests when in multi-process mode) is going to be difficult or impossible to debug, especially if you have to run the target over and over in order to make the bug manifest. If you have a repeatable bug, no big deal, break on the fork from the parent process and attach to the child in a second lldb instance. Otherwise, read on.

Install GDB

Don't make the mistake of thinking you can just brew install gdb. Currently this is version 10.2 and it's mostly broken, with at least two annoying bugs as of April 29th 2021, but the big one is https://sourceware.org/bugzilla/show_bug.cgi?id=24069
