yash-syntax-0.9.0

[0.9.0] - 2024-06-09

Added

• parser::SyntaxError::RedundantToken variant
• parser::lex::ParseOperatorError struct

Changed

• Implementations of FromStr for syntactic elements like Assign and
  SimpleCommand now fails with SyntaxError::RedundantToken if the input
  string contains a token that is not part of the element.
• Lexer::source_string is no longer generic. The argument type is now
  Range<usize> instead of a generic implementor of
  SliceIndex<[SourceChar], Output = [SourceChar]>.
• Word::parse_tilde_front no longer delimits the tilde expansion at an
  unquoted : character.
• WordLexer::braced_param now returns Err(SyntaxError::EmptyParam) if {
  is not followed by any name characters. Previously, it returned
  Err(SyntaxError::UnclosedParam{…}) if { was followed by a non-name
  character other than }.
• impl std::fmt::Display for SimpleCommand now prints the command words
  after the redirections if there are no assignments and the first word looks
  like a keyword.
• TryFromOperatorError is now a unit struct rather than an empty normal
  struct.

Fixed

• A newline after a bar in a pipeline was not parsed correctly if it appeared as
  a result of alias substitution.
• Alias substitution was not performed as expected for a token that follows a
  result of blank-ending alias substitution if there is a line continuation
  between them.
• Character location indexes were not calculated correctly after an alias
  substitution changed the length of the source code.

yash-semantics-0.2.0

[0.2.0] - 2024-06-09

Added

• Support for the ErrExit shell option in multi-command pipelines

Changed

• External dependency versions
  • yash-env 0.1.0 → 0.2.0
  • yash-syntax 0.8.0 → 0.9.0
• In the expansion::initial module:
  • ValueState was renamed to Vacancy.
  • EmptyError was renamed to VacantError.
  • EmptyError::state was renamed to VacantError::vacancy.
• expansion::ErrorCause::EmptyExpansion was renamed to expansion::ErrorCause::VacantExpansion.
• <expansion::Error as handle::Handle>::handle now returns Divert::Exit
  instead of Divert::Interrupt when the ErrExit shell option is applicable.
• expansion::glob::glob no longer requires search permission for the parent
  directory of the last pathname component in the pattern when the last
  component contains a pattern character.
• <yash_syntax::syntax::FunctionDefinition as command::Command>::execute now
  prints its error message in prettier format.
• command::simple_command::replace_current_process now uses System::shell_path
  to find the shell executable when it needs to fall back to the shell.
• trap::run_trap_if_caught now takes a yash_env::signal::Number argument
  instead of a yash_env::trap::Signal.

Fixed

• A for loop without any words after in now correctly returns an exit status
  of 0 rather than keeping the previous exit status.
• <TextUnit as Expand>::expand now correctly expands an unset parameter with a
  switch to an empty string regardless of the Unset shell option. Previously,
  it would expand to an empty string only if the Unset shell option was on.
• The parameter expansion of an unset variable with a Length modifier now
  correctly expands to 0 rather than an empty string.
• expansion::glob::glob now handles backslash escapes in glob patterns
  correctly.
• trap::run_traps_for_caught_signals, trap::run_trap_if_caught, and
  trap::run_exit_trap now propagate the exit status of the executed trap
  action if it is interrupted by a shell error raising Divert::Interrupt(_).
• trap::run_exit_trap is now called on the exit of a subshell that is running
  a command substitution, an asynchronous and-or list, or a job-controlled
  pipeline.

  3. old_mask: Option<&mut Vec<signal::Number>>,
• system::virtual::SignalEffect::of now takes a signal::Number parameter
  instead of a trap::Signal. This function is now const.
• The type parameter constraint for subshell::Subshell is now
  F: for<'a> FnOnce(&'a mut Env, Option<JobControl>) -> Pin<Box<dyn Future<Output = ()> + 'a>> + 'static.
  The Output type of the returned future has been changed from
  semantics::Result to ().
