#2Love reading your posts Tristan, a question about the choice of Rust. Was it specifically based on the previous experience you and your groupmates drew on or were these languages assigned to students? Was there any point in time where you and your team were trying to optimize your compiler?

#3I wonder how Racket would compare. I’ve written some DSLs at an old job for Racket and found the libraries for language design almost unreasonably powerful (and maybe unreasonably complicated as well). The dynamic typing would also help in reducing the amount of code.

#4I'm sad that no one wrote it in the subset of Java that it was going to compile.

We got to choose. Everyone on our team had some experience in Rust and OCaml, the two of us more experienced in Rust were pretty indifferent between OCaml and Rust, and our third teammate wanted to use the project to learn more Rust so that's what we went with.

Yah I figure it would be like Python but better if you were allowed to use the language design libraries. However the course specifically forbids standard library components that are designed for implementing languages so that you have to write the parser and things yourself.

#7I really wish when counting code that people would use one of the more modern code counters, or at least use cloc. Tokei, loc, scc, polyglot, loccount or gocloc give a much better idea over wc because they account for comments and blank lines and in the case of scc and tokei strings.
I had a similar experience in university. Class had to implement a modified Turing machine. We could use whatever language we wanted. On person did it in C++ and it was several hundred lines. Another in Java which was slightly smaller. I implemented mine in Python and it was small enough to print on a single piece of paper. I think it was something like 30 lines or so. I exploited break statements to make it terse but readable. It did mean I was marked down a bit for them but it was by far the shortest program in the class.

A few groups did give me output from a modern line counter, often Tokei or loc. I mention in the post that the ratios between source lines, word count lines and bytes were pretty similar across all projects. If people want to get a sense of how that compares to their intuitions in source lines they can use the ratio from our Rust project to convert.
I ended up using raw lines for comparison because for relative measurement it didn't matter for the above reason, and I knew everyone had the same `wc` and I could get them to send me the output of the `wc {glob}` version that lists lines and bytes of all files so that I could drill down into which parts were different.

#9I haven't made it through the whole thing yet, but I do want to register a vote in favor of using Lines Of Code count as a rough measure of program complexity. I think it's a perfectly valid things to do, provided that it isn't used as an evaluation metric and nobody is gaming it, and everyone is a reasonably good programmer, not doing crazy things like trying to stuff a massive algorithm onto one line to be clever, or copy-pasting the same code in 20 places because they don't understand functions and classes.

They probably wouldn't have been able to finish the project in time.
