What Hacker News says

10 sources
Not impressed by shell incantations. What would sell such a tool to me is a feature to replace those with new and more intuitive syntax. And a terser one, too. Holding on to how things are done in the shell is not a thing to be proud of. I think a lot of us around here stopped counting the times we got tripped by globbing, forgetting or misplacing one special character in a ${} block, or quoting. Let those monstrosities die already. Please. There's this tool -- https://github.com/ejholmes/walk -- that is pretty good and I liked it but dropped it for the same reasons: it leaves the heavy lifting to you and it depends on your mastery in the black arts. Now obviously I'm not managing huge projects but nowadays https://github.com/casey/just serves me just fine for everything I need.
In Redo: A recursive, general-purpose build system

Show HN: Just, a command runner written in Rust

Just lets you save and run commands from files with a terse, readable syntax similar to Make: build: cc *.c -o main # test everything test-all: build ./test --all # run a specific test test TEST: build ./test --test {{TEST}} It is cross-platform, written in Rust, and actively maintained on GitHub: https://github.com/casey/just/ Just has a bunch of nice features: - Can be invoked from any subdirectory - Arguments can be passed from the command line - Static error checking that catches syntax errors and typos - Excellent error messages with source context - The ability to list recipes from the command line - Recipes can be written in any language - Works on Linux, macOS, and Windows - And much more! Just doesn't replace Make, or any other build system, but it does replace reverse-searching

your command history, telling colleagues the weird flags they need to pass to do the thing, and forgetting how to run old projects.
