GoKawiiluutils coreutils 0.11.0 adds compiler-style error diagnostics to command-line tools
The uutils project's coreutils release 0.11.0 introduces caret-style error reporting, similar to Rust's compiler, for commands whose arguments act as mini-languages, such as tr, cut, chmod and sort. When a parse error occurs and stderr is a terminal, the tool now echoes the offending argument, points a caret at the exact problem spot, and often adds a help line explaining correct syntax. The feature was inspired by uutils' own awk implementation, which already used similar diagnostics for parsing awk scripts.
