Papyrus - A rust REPL and script running tool.
This project is no longer maintained.
For a similar REPL tool with a refreshing way to interact with data, checkout the
papyrus=> 2+2 papyrus [out0]: 4
Papyrus creates a Rust REPL in your terminal. Code can be typed in, line by line with feedback on the evaluation, or code can be injected via stdin handles. Each code snippet is evaluated on an expression based system, so terminating with a semi-colon requires more input.
[lib] papyrus=> 2+2 papyrus [out0]: 4 [lib] papyrus=> println!("Hello, world!"); [lib] papyrus.> out0 * out0 Hello, world! papyrus [out1]: 16 [lib] papyrus=> :help help -- prints the help messages cancel | c -- returns to the root class exit -- sends the exit signal to end the interactive loop Classes: edit -- Edit previous input mod -- Handle modules Actions: mut -- Begin a mutable block of code [lib] papyrus=> :exit [lib] papyrus=> Thanks for using papyrus!
Papyrus can be installed from
crates.io or building from source on github.
The default installation feature set requires a
nightly toolchain, but
stable can be used with
fewer features enabled.
To install with all features:
rustup toolchain add nightly cargo +nightly install papyrus
To install on stable without racer completion:
cargo +stable install papyrus --no-default-features --features="format,runnable"
Papyrus has features sets:
- format: format code snippets using
- racer-completion: enable code completion using
racer. Requires a nightly compiler
- runnable: papyrus can be run, without needing to manually handle repl states and output
All features are enabled by default.
Papyrus leverages installed binaries of both
rustc. This requirement may lift in the
future but for now, any user wanting to use Papyrus will need an installation of Rust.
