This isn't just another CPU temperature printer. I created this while designing my status bar, out of frustration for the traditional approach approach of either filtering programs that don't output exactly what you want, or catting /sys files with long file paths you're inevitably going to assign to variables, and whose output is probably to require math.
Doing this once is no big deal, but if you're trying to mix and match, experiment with different layouts, and you're using shell functions & aliases, grepping all sorts of programs with regular expressions that may or may not break one day, or god forbid you want median temperatures, or want to calculate your own average (package temp isn't the same)? Yeah.. That's when the "there's got to be a better way" cogs start turning.
No more sensors | rg "^Pack[^\+]+([^ ]+)" -o -r '$1' shenanigans.
Sequentially evaluated formatting expressions as command line arguments.. Let me explain. Coretempf is used by providing a sequence of one of three types of arguments: a control flag, a segment, or a parameterized segment. These are then evaluated sequentially as they are being parsed, rather than first parsed and then evaluated in no particular order. Think of it like inputting code into a REPL (read, eval, print, loop), except each expression is an argument rather than a line. The output is the resulting string that each argument played a role in constructing. This makes sequence very important, especially for control flags, since unlike options, it matters whether or not you --turn-something-on before you --output-something, and likewise, --turn-it-off after --outputting-something-else
In essence, Coretempf is a string builder.
In the future, I might rename this project, as CPU core temperatures aren't the only thing suffering from the problem I aimed to solve. A unified way to flexibly format all sorts of performance and hardware statistics is an intriguing idea; imagine 100% (80% realistically) of the data on your status bar coming from one optimized binary, built in Rust. It would be insanely portable.
