Struct ParserOptions 

pub struct ParserOptions {
    pub lang: Option<String>,
    pub source_type: Option<String>,
    pub ast_type: Option<String>,
    pub range: Option<bool>,
    pub tokens: Option<bool>,
    pub preserve_parens: Option<bool>,
    pub show_semantic_errors: Option<bool>,
}

Fields

lang: Option<String>

Treat the source text as js, jsx, ts, tsx or dts.

source_type: Option<String>

Treat the source text as script or module code.

ast_type: Option<String>

Return an AST which includes TypeScript-related properties, or excludes them.

'js' is default for JS / JSX files. 'ts' is default for TS / TSX files. The type of the file is determined from lang option, or extension of provided filename.

range: Option<bool>

Controls whether the range property is included on AST nodes. The range property is a [number, number] which indicates the start/end offsets of the node in the file contents.

@default false

tokens: Option<bool>

Controls whether parser should return tokens.

This option is not stable yet, and only available with experimental raw transfer.

@default false

preserve_parens: Option<bool>

Emit ParenthesizedExpression and TSParenthesizedType in AST.

If this option is true, parenthesized expressions are represented by (non-standard) ParenthesizedExpression and TSParenthesizedType nodes that have a single expression property containing the expression inside parentheses.

@default true

show_semantic_errors: Option<bool>

Produce semantic errors with an additional AST pass. Semantic errors depend on symbols and scopes, where the parser does not construct. This adds a small performance overhead.

@default false
