Uutils coreutils adds compiler-style error diagnostics in version 0.11.0
Terminal parse errors will highlight specific culprit characters alongside explanatory syntax help.
The short version
- Starting with version 0.11.0, uutils coreutils echoes command arguments and points carets at parse errors when stderr is attached to a terminal.[Hacker News]
- Shared parsers, including the suite's SIZE argument handler, now provide standardized diagnostic reports across multiple utilities.[Hacker News]
- Non-terminal outputs automatically revert to single-line messages, while terminal sessions respecting NO_COLOR display plain-text reports.[Hacker News]
- Developers plan to extend the shared diagnostic rendering crate to other projects such as findutils and sed.[Hacker News]
Key facts
- Starting in version 0.11.0, uutils coreutils generates compiler-style diagnostic reports with carets and syntax help when stderr is connected to a terminal.[Hacker News]
- The diagnostic concept was inspired by uutils awk and implemented using the ariadne library.[Hacker News]
- Commands sharing the suite's SIZE parser will provide uniform diagnostic reports.[Hacker News]
- When stderr is redirected away from a terminal, errors default to a traditional single line, while NO_COLOR settings render plain-text diagnostics without escape codes.[Hacker News]
- The diagnostic engine resides in uucore::diagnostics, with ongoing efforts to integrate it into findutils and sed.[Hacker News]
