Struct Command 

pub struct Command { /* private fields */ }

A control sequence with its greedily-attached argument groups.

Implementations

impl Command

pub fn control_word(&self) -> Option<ControlWord>

The leading CONTROL_WORD token, or None for a control symbol. The grammar bumps the control word as the command’s first token.

pub fn name(&self) -> Option<String>

The control-word name (leading \ stripped), or None for a control symbol.

pub fn control_word_range(&self) -> Option<TextRange>

The range of the leading CONTROL_WORD token (the \foo itself, backslash included), or None for a control symbol. Callers use this to underline just the control word rather than the whole node, which may carry greedily-attached argument groups.

pub fn nth_group(&self, n: usize) -> Option<Group>

The n-th GROUP argument, if present. Filters GROUP only, so OPTIONAL arguments do not shift brace indexing (\cmd[o]{a} → nth_group(0) is {a}).

pub fn groups(&self) -> impl Iterator<Item = Group>

The GROUP argument nodes, in source order.

pub fn optionals(&self) -> impl Iterator<Item = Optional>

The OPTIONAL argument nodes, in source order.

pub fn nth_group_text(&self, n: usize) -> Option<String>

The literal text inside the n-th GROUP argument, braces dropped. Returns None when there is no n-th group or it holds non-token content (a nested command — not a flat literal). See Group::inner_text.

pub fn nth_group_inner(&self, n: usize) -> Option<(TextRange, String)>

The byte range of the content inside the n-th GROUP argument together with that inner text — the location-aware counterpart to Command::nth_group_text. See Group::inner.

pub fn first_group_range(&self) -> TextRange

The byte range of this command spanning its control word through the end of its first {…} group — e.g. \label{key} up to the closing brace of {key}. Deliberately not SyntaxNode::text_range, which the greedy parser may stretch over a second group it attached without knowing arity (\label{a}\n{…}; decision #8). Falls back to the full command range when the first group is absent.
