This is a little thing I put together to let you write mdbooks where you can test the output of CLI code examples with trycmd.

I've provided an example .trycmd, mdbook chapter page, and the mdbook plugin. Please note that the example .trycmd has a bunch of odd stuff in it; I'm using this for a jj tutorial, and you need to do certain things to ensure reproducibility there.

I'm not making this into a github repo yet because there's a few caveats and i want you to understand them before you give it a go:

this, like trycmd generally, executes whatever you tell it to in a tempdir. Don't try to colorize the output of rm -rf / --no-preserve-root and then get mad at me.
my code is bad. i put it together last night and this morning. no error handling, debug lines still in there, i didn't even run rustfmt or clippy.
unlike {#include in rustdoc, the syntax highlighting can add lines, so the lines don't correspond to the .trycmd directly. It'll take some trial and error to get them right.

so, why is oil's price negative?

(note: I am a software developer who has an interest in finance. This is my understanding. I am not a professional.)

first, what does that even mean? so, the "price of oil" is the price of "WTI Crude", which is a specific kind of oil. There are multiple kinds of oil with multiple prices.

Why is it negative? to understand this, we also have to understand why WTI is the price of oil: that is, it's the kind of oil that underpins the New York Mercantile Exchange's oil futures contracts. The NYMEX is kind of like the stock market, but for commodities, aka stuff.

In no particular order:
