Snapshot of parser-visible zsh option state.

The fields here intentionally cover options that can change syntax, tokenization, or word interpretation. They are not a full zsh runtime option table. Use ZshOptionState::zsh_default for native zsh parsing, then apply setopt, unsetopt, or emulate effects when a caller has already discovered them.

Fields

sh_word_split: OptionValue

Whether unquoted parameter expansion is treated as eligible for shell-style word splitting.

glob_subst: OptionValue

Whether parameter expansion results are treated as glob patterns.

rc_expand_param: OptionValue

Whether array parameters can participate in brace-like expansion.

glob: OptionValue

Whether ordinary filename generation is enabled.

nomatch: OptionValue

Whether unmatched filename-generation patterns are treated as errors.

null_glob: OptionValue

Whether unmatched filename-generation patterns can expand to nothing.

csh_null_glob: OptionValue

Whether csh-style null glob handling is enabled.

extended_glob: OptionValue

Whether zsh extended glob operators are enabled.

ksh_glob: OptionValue

Whether ksh-style glob operators are enabled.

sh_glob: OptionValue

Whether sh-compatible glob parsing is enabled.

bare_glob_qual: OptionValue

Whether unparenthesized zsh glob qualifiers are enabled.

glob_dots: OptionValue

Whether glob patterns match dotfiles without an explicit dot.

equals: OptionValue

Whether leading = words are eligible for command-path expansion.

magic_equal_subst: OptionValue

Whether assignment-like words can apply = expansion after the first equals sign.

sh_file_expansion: OptionValue

Whether file expansion follows sh-compatible ordering.

glob_assign: OptionValue

Whether assignment values can be parsed as glob assignments.

ignore_braces: OptionValue

Whether brace characters should be treated literally instead of as zsh brace syntax.

ignore_close_braces: OptionValue

Whether unmatched closing braces should be treated literally.

brace_ccl: OptionValue

Whether character-class brace expansion syntax is enabled.

ksh_arrays: OptionValue

Whether array indexing follows ksh-style zero-based behavior.

ksh_zero_subscript: OptionValue

Whether subscript zero is accepted with ksh-style array semantics.

short_loops: OptionValue

Whether zsh short loop forms are accepted.

short_repeat: OptionValue

Whether zsh short repeat forms are accepted.

rc_quotes: OptionValue

Whether doubled single quotes are decoded inside single-quoted strings.

interactive_comments: OptionValue

Whether # starts comments in interactive-style zsh parsing contexts.

c_bases: OptionValue

Whether C-style numeric base prefixes are accepted in arithmetic text.

octal_zeroes: OptionValue

Whether leading zeroes are interpreted as octal arithmetic literals.

Implementations

impl ZshOptionState

pub const fn zsh_default() -> Self

Default zsh option state used for native zsh parsing.

This is the parser’s baseline before source-level commands such as emulate, setopt, and unsetopt are considered.

pub fn for_emulate(mode: ZshEmulationMode) -> Self

Return the option state implied by emulate <mode>.

This models the subset of emulation effects that the parser currently needs. Callers can further refine the returned state with ZshOptionState::apply_setopt and ZshOptionState::apply_unsetopt.

pub fn apply_setopt(&mut self, name: &str) -> bool

Apply a zsh setopt-style option name to this snapshot.

Names are matched with zsh-style aliases, underscores, and no_ prefixes where supported by this parser. Returns true when the option name was recognized and this snapshot was updated.

pub fn apply_unsetopt(&mut self, name: &str) -> bool

Apply a zsh unsetopt-style option name to this snapshot.

Names are matched with zsh-style aliases, underscores, and no_ prefixes where supported by this parser. Returns true when the option name was recognized and this snapshot was updated.

pub fn merge(&self, other: &Self) -> Self

Merge two option snapshots field by field.

Each field preserves a definite value only when both inputs agree. This is useful for conservative joins across control-flow paths.

Trait Implementations

impl Clone for ZshOptionState

fn clone(&self) -> ZshOptionState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ZshOptionState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ZshOptionState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ZshOptionState

fn eq(&self, other: &ZshOptionState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
