Let's Build Snake with Rust
Since 2016, Rust has been voted the “most loved programming language” every year in the Stack Overflow Developer Survey by what appears to be a growing margin, and after checking it out for myself, it’s pretty clear why. Rust offers a plethora of features you’d expect from a modern language and addresses pain points that are present in many others. It competes in the same kind of space occupied by
Rustのclapでcliのコマンドやオプションをenumで取得する
Rust Advent Calendar 2024 19 日目 この記事は Rust Advent Calendar 2024 の 19 日目として書いています。 今日見たら偶然 19 日が空いていたので 9 日目同様にせっかくなら入れるかと思って入れています。 昨日は @sotanengel さんによる 「docs.rs 書くのめんどくさくない？」をできるだけ楽にした話 でした。 概要 Rust に慣れるがてら簡単な cli を書いてみようと思い、コマンドをいい感じに出来るライブラリを簡単にググって見つけたので、備忘録としてコマンドを struct にマッピングする周りを書き残そうと思いました。 いくつかコードが出てきますが、ベースの Cargo.toml はこちらです。 [package] name = "cli-with-clap" version = "0.1.0" edition
"Rules" that terminal programs follow
Recently I’ve been thinking about how everything that happens in the terminal is some combination of: Your operating system’s job Your shell’s job Your terminal emulator’s job The job of whatever program you happen to be running (like top or vim or cat) The first three (your operating system, shell, and terminal emulator) are all kind of known quantities – if you’re using bash in GNOME Terminal on
ParsingLs - Greg's Wiki
The ls(1) command is pretty good at showing you the attributes of a single file (at least in some cases), but when you ask it for a list of files, there's a huge problem: Unix allows almost any character in a filename, including whitespace, newlines, commas, pipe symbols, and pretty much anything else you'd ever try to use as a delimiter except NUL. There are proposals to try and "fix" this within
Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones? | Hacker News
I use relatively few TUI's, and don't know much about them—about what good, convenient UX flows in TUI's can look like. I want to write some in Emacs. Do you have particularly nice examples of TUI's that deserve to be known and imitated? I know there's a lot of abandoned programs from the pre-GUI era that refined TUI's to a high level.(I'm only familiar with a handful of modern ones in Emacs—Magit
Building an interactive shell in Golang
Go is great for building command-line applications. We built one: Dolt, the world's first version-controlled SQL database. We wrote our own command line parser for handling all of Dolt's subcommands and arguments, but maybe we shouldn't have. There are lots of great ones out there that if we might have used instead if we were starting the project today: spf13/cobra has great support for code gener
Difftastic, a structural diff tool that understands syntax | Hacker News
For those who don't already know, this is built on tree-sitter (https://tree-sitter.github.io/tree-sitter/) which does for parsing what LSP does for analysis. That is, it provides a standard interface for turning code into an AST and then making that AST available to clients like editors and diff tools. Instead of a neat tool like this having to support dozens of languages, it can just support tre
