Struct Interpreter 

pub struct Interpreter<'a> { /* private fields */ }

The AWK interpreter runtime

Implementations

impl<'a> Interpreter<'a>

pub fn call_function<W: Write>( &mut self, name: &str, args: &[Expr], location: SourceLocation, output: &mut W, ) -> Result<Value>

Call a function with special handling for builtins that need AST access

impl<'a> Interpreter<'a>

pub fn eval_expr(&mut self, expr: &Expr) -> Result<Value>

Evaluate an expression (for contexts where we don’t have output, like condition checking)

pub fn eval_expr_with_output<W: Write>( &mut self, expr: &Expr, output: &mut W, ) -> Result<Value>

Evaluate an expression with a writer for function calls that produce output

pub fn assign_to_lvalue(&mut self, target: &Expr, value: Value) -> Result<()>

impl<'a> Interpreter<'a>

pub fn execute_block<W: Write>( &mut self, block: &Block, output: &mut W, ) -> Result<StmtResult>

pub fn execute_stmt<W: Write>( &mut self, stmt: &Stmt, output: &mut W, ) -> Result<StmtResult>

impl<'a> Interpreter<'a>

pub fn new(program: &'a Program) -> Self

pub fn set_args(&mut self, args: Vec<String>)

Set command line arguments (ARGC and ARGV)

pub fn set_fs(&mut self, fs: &str)

Set the field separator

pub fn set_posix_mode(&mut self, enabled: bool)

Set POSIX strict mode

pub fn set_traditional_mode(&mut self, enabled: bool)

Set traditional AWK mode (no gawk extensions)

pub fn set_variable(&mut self, name: &str, value: &str)

Set a variable before execution

pub fn set_filename(&mut self, filename: &str)

Set the current filename (FILENAME)

pub fn run<R: BufRead, W: Write>( &mut self, inputs: Vec<R>, output: &mut W, ) -> Result<i32>

Run the AWK program with given input
