Struct ucglib::build::FileBuilder

pub struct FileBuilder<'a, Stdout, Stderr> where
    Stdout: Write + Clone,
    Stderr: Write + Clone,  {
    pub environment: Rc<RefCell<Environment<Stdout, Stderr>>>,
    pub last: Option<Rc<Val>>,
    pub out: Option<Rc<Val>>,
    // some fields omitted
}

Builder handles building ucg code for a single file.

Fields

environment: Rc<RefCell<Environment<Stdout, Stderr>>>

last: Option<Rc<Val>>

out: Option<Rc<Val>>

Implementations

impl<'a, Stdout, Stderr> FileBuilder<'a, Stdout, Stderr> where
    Stdout: Write + Clone,
    Stderr: Write + Clone, 

pub fn new<P: Into<PathBuf>>(
    working_dir: P,
    import_paths: &'a Vec<PathBuf>,
    stdout: Stdout,
    stderr: Stderr
) -> Self

Constructs a new Builder.

pub fn clone_builder(&self) -> Self

pub fn set_strict(&mut self, strict: bool)

pub fn build<P: Into<PathBuf>>(&mut self, file: P) -> Result<(), Box<dyn Error>>

Builds a ucg file at the named path.

pub fn enable_validate_mode(&mut self)

Puts the builder in validation mode.

Among other things this means that assertions will be evaluated and their results will be saved in a report for later output.

pub fn eval_stmts(
    &mut self,
    ast: Vec<Statement>,
    path: Option<PathBuf>
) -> Result<(), Box<dyn Error>>

Builds a list of parsed UCG Statements.

pub fn repl(
    &mut self,
    editor: Editor<()>,
    config_home: PathBuf
) -> Result<(), Box<dyn Error>>

pub fn eval_input(
    &mut self,
    input: OffsetStrIter<'_>,
    path: Option<PathBuf>
) -> Result<Rc<Val>, Box<dyn Error>>

pub fn eval_string(&mut self, input: &str) -> Result<Rc<Val>, Box<dyn Error>>

Evaluate an input string as UCG.

pub fn eval_expr(&mut self, expr: Expression) -> Result<Rc<Val>, Box<dyn Error>>

pub fn get_out_by_name(&self, name: &str) -> Option<Rc<Val>>

pub fn assert_results(&self) -> bool

pub fn assert_summary(&self) -> String
