You are writing simple budgeting softare. A Budget consists of a total limit, represented as a positive integer, and a dictionary of category limits, represented as a map from strings to integers. For example:
{
"total_limit": 50,
"category_limits": {
"food": 10,
"rent": 11,
"candles": 49
}
Macro hygiene is the concept of macros that work in all contexts; they don't affect and aren't affected by anything around them. Ideally all macros would be fully hygienic, but there are lots of pitfalls and traps that make it all too easy to accidentally write unhygienic macros. This guide attempts to provide a comprehensive resource for writing the most hygienic macros.
First, a little aside on the details of Rust's module system, and specifically paths; it is
| #!/usr/bin/awk -f | |
| # This program is a copy of guff, a plot device. https://github.com/silentbicycle/guff | |
| # My copy here is written in awk instead of C, has no compelling benefit. | |
| # Public domain. @thingskatedid | |
| # Run as awk -v x=xyz ... or env variables for stuff? | |
| # Assumptions: the data is evenly spaced along the x-axis | |
| # TODO: moving average |

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct
Monads and delimited control are very closely related, so it isn’t too hard to understand them in terms of one another. From a monadic point of view, the big idea is that if you have the computation m >>= f, then f is m’s continuation. It’s the function that is called with m’s result to continue execution after m returns.
If you have a long chain of binds, the continuation is just the composition of all of them. So, for example, if you have
m >>= f >>= g >>= hthen the continuation of m is f >=> g >=> h. Likewise, the continuation of m >>= f is g >=> h.
