Changes: - Add ParserBuilderError enum with 8 validation error variants - Refactor builder methods to return Result<&mut Self, ParserBuilderError> - Implement comprehensive unit validation (57 valid units including k/m/g/t) - Add cross-validation between builder settings (default_unit vs allow_list) - Detect conflicts (b_byte_count with 'b' unit, '%' with size units) - Update all call sites (sort, du, df, od) to handle new error types - Fix invalid '%' unit in sort's parse_byte_count allow_list Benefits: - Configuration errors detected immediately (not during parsing) - Clear error messages listing invalid/conflicting settings - Maintains backward compatibility through explicit error reporting Files modified: - src/uucore/src/lib/features/parser/parse_size.rs (core implementation) - src/uu/sort/src/sort.rs (error handling + fix invalid '%') - src/uu/du/src/du.rs (error handling) - src/uu/df/src/df.rs (error handling) - src/uu/od/src/od.rs (error handling) --- src/uu/df/src/df.rs | 1 + src/uu/du/src/du.rs | 3 + src/uu/od/src/od.rs | 3 + src/uu/sort/src/sort.rs | 11 +- .../src/lib/features/parser/parse_size.rs | 333 +++++++++++++++++- 5 files changed, 335 insertions(+), 16 deletions(-) diff --git a/src/uu/df/src/df.rs b/src/uu/df/src/df.rs index d7746b9150e..b6a850c378e 100644 --- a/src/uu/df/src/df.rs +++ b/src/uu/df/src/df.rs @@ -167,6 +167,7 @@ impl Options { ), ParseSizeError::ParseFailure(s) => OptionsError::InvalidBlockSize(s), ParseSizeError::PhysicalMem(s) => OptionsError::InvalidBlockSize(s), + ParseSizeError::BuilderConfig(e) => OptionsError::InvalidBlockSize(e.to_string()), })?, header_mode: { if matches.get_flag(OPT_HUMAN_READABLE_BINARY) diff --git a/src/uu/du/src/du.rs b/src/uu/du/src/du.rs index 1b8084e2ebb..0310a5a52b6 100644 --- a/src/uu/du/src/du.rs +++ b/src/uu/du/src/du.rs @@ -1490,6 +1490,9 @@ fn format_error_message(error: &ParseSizeError, s: &str, option: &str) -> String ParseSizeError::SizeTooBig(_) => { translate!("du-error-argument-too-large", "option" => option, "value" => s.quote()) } + ParseSizeError::BuilderConfig(e) => { + format!("invalid configuration for {option}: {e}") + } } } diff --git a/src/uu/od/src/od.rs b/src/uu/od/src/od.rs index e8f9841b162..914a02e20e3 100644 --- a/src/uu/od/src/od.rs +++ b/src/uu/od/src/od.rs @@ -804,5 +804,8 @@ fn format_error_message(error: &ParseSizeError, s: &str, option: &str) -> String ParseSizeError::SizeTooBig(_) => { translate!("od-error-argument-too-large", "option" => option, "value" => s.quote()) } + ParseSizeError::BuilderConfig(e) => { + format!("invalid configuration for {option}: {e}") + } } } diff --git a/src/uu/sort/src/sort.rs b/src/uu/sort/src/sort.rs index 071163c5aee..d2595b9d4b0 100644 --- a/src/uu/sort/src/sort.rs +++ b/src/uu/sort/src/sort.rs @@ -319,10 +319,10 @@ impl GlobalSettings { // GNU sort (8.32) invalid: b, B, 1B, p, e, z, y let size = Parser::default() .with_allow_list(&[ - "b", "k", "K", "m", "M", "g", "G", "t", "T", "P", "E", "Z", "Y", "R", "Q", "%", - ]) - .with_default_unit("K") - .with_b_byte_count(true) + "b", "k", "K", "m", "M", "g", "G", "t", "T", "P", "E", "Z", "Y", "R", "Q", + ])? + .with_default_unit("K")? + .with_b_byte_count(true)? .parse(input.trim())?;
