yash-env-0.2.1

[0.2.1] - 2024-07-12

Added

• Env::is_interactive
• impl yash_system::alias::Glossary for Env
• input::Echo
  • This is a decorator of Input that implements the behavior of the verbose shell option.
• input::FdReader is now marked #[must_use].
• variable::VariableSet::get_scalar
  • This is a convenience method that returns a scalar variable as a Cow<str>.
• Variable name constants in the variable module:
  CDPATH, ENV, HOME, IFS, LINENO, OLDPWD, OPTARG, OPTIND,
  PATH, PPID, PS1, PS2, PS4, PWD
• Variable initial value constants in the variable module:
  IFS_INITIAL_VALUE, OPTIND_INITIAL_VALUE, PS1_INITIAL_VALUE_NON_ROOT,
  PS1_INITIAL_VALUE_ROOT, PS2_INITIAL_VALUE, PS4_INITIAL_VALUE
• impl System for &SharedSystem and impl trap::SignalSystem for &SharedSystem
  • This allows SharedSystem to be used as a system behind a non-mutable reference.

Changed

• External dependency versions:
  • Rust 1.70.0 → 1.77.0
  • yash-syntax 0.9.0 → 0.10.0
• Internal dependency versions:
  • annotate-snippets 0.10.0 → 0.11.4
• All inherent methods of SharedSystem now take &self instead of &mut self:
  • SharedSystem::read_async
  • SharedSystem::write_all
  • SharedSystem::print_error

Deprecated

• input::FdReader::set_echo in favor of input::Echo

Fixed

• stack::Stack::loop_count no longer counts loops below a Frame::Trap(_) frame.
• Possible undefined behavior in RealSystem::times
