Struct shelp::Repl

pub struct Repl<L: LangInterface = DefaultLangInterface> { /* fields omitted */ }

Repl interacts with the terminal to provide easy interactive shells.

Configuration:

• leader What to print as the prompt:

  > <some-code>
  ^^- leader
  

• continued_leader If the command is more than one line long, what to print on subsequent lines

  > <some-code>
  . <some-code>
  

• path Path to a file to use as persistent history. If given, on construction, the history will be populated from the contents of this file, and will automatically write it to the file on being dropped. In case a path is not specified, the history is lost when Repl is dropped.

• capacity The maximum amount of commands stored in the history. Default capacity is 64. If there are already 64 commands in the history, the oldest one will be forgotten.

Implementations

impl<L: LangInterface> Repl<L>

pub fn iter(self, color: Color) -> ReplIter<L>

Shorthand to get iterator from self

impl Repl<DefaultLangInterface>

pub fn newd(
    leader: &'static str,
    continued_leader: &'static str,
    path: Option<PathBuf>
) -> Self

Create a Repl with default language interface.

pub fn with_capacityd(
    leader: &'static str,
    continued_leader: &'static str,
    capacity: usize,
    path: Option<PathBuf>
) -> Self

Create a Repl with default language interface, and specified history capacity.

impl<L: LangInterface> Repl<L>

pub fn new(
    leader: &'static str,
    continued_leader: &'static str,
    path: Option<PathBuf>
) -> Self

Create a Repl with specified language interface.

pub fn with_capacity(
    leader: &'static str,
    continued_leader: &'static str,
    capacity: usize,
    path: Option<PathBuf>
) -> Self

Create a Repl with specified language interface, and specified history capacity.

pub fn next(&mut self, colour: Color) -> Result<String>

The main function, gives the next command

Trait Implementations

impl<L: LangInterface> Drop for Repl<L>

pub fn drop(&mut self)

Executes the destructor for this type.
