This means that each - * line can be run in a separate task, and the only limiting factor is that all - * local bound variables are encodable. - * - * This is accomplished by feeding in generated input to rustc for execution in - * the JIT compiler. Currently input actually gets fed in three times to get - * information about the program. - * - * - Pass #1 - * In this pass, the input is simply thrown at the parser and the input comes - * back. This validates the structure of the program, and at this stage the - * global items (fns, structs, impls, traits, etc.) are filtered from the - * input into the "global namespace". These declarations shadow all previous - * declarations of an item by the same name. - * - * - Pass #2 - * After items have been stripped, the remaining input is passed to rustc - * along with all local variables declared (initialized to nothing). This pass - * runs up to typechecking. From this, we can learn about the types of each - * bound variable, what variables are bound, and also ensure that all the - * types are encodable (the input can actually be run). - * - * - Pass #3 - * Finally, a program is generated to deserialize the local variable state, - * run the code input, and then reserialize all bindings back into a local - * hash map. This code is then run in the JIT engine provided by the rust - * compiler. - * - * - Pass #4 - * Once this code runs, the input has fully been run and the hash map of local - * variables from TLS is read back into the local store of variables. This is - * then used later to pass back along to the parent rusti task and then begin - * waiting for input again. - * - * - Pass #5 - * When running rusti code, it's important to consume ownership of the LLVM - * jit contextual information to prevent code from being deallocated too soon - * (before drop glue runs, see #7732). For this reason, the jit context is - * consumed and also passed along to the parent task. The parent task then - * keeps around all contexts while rusti is running. This must be done because - * tasks could in theory be spawned off and running in the background (still - * using the code). - * - * Encoding/decoding is done with EBML, and there is simply a map of ~str -> - * ~[u8] maintaining the values of each local binding (by name). - */ - -#[link(name = "rusti", - vers = "0.9-pre", - uuid = "7fb5bf52-7d45-4fee-8325-5ad3311149fc", - url = "https://github.com/mozilla/rust/tree/master/src/rusti")]; - -#[license = "MIT/ASL2"]; -#[crate_type = "lib"]; - -#[feature(globs)]; - -extern mod extra; -extern mod rustc; -extern mod syntax; - -use std::{libc, io, os, task}; -use std::cell::Cell; -use extra::rl::CompletionCb; -use extra::rl; - -use rustc::driver::{driver, session}; -use rustc::back::link::jit; -use syntax::{ast, codemap, diagnostic}; -use syntax::ast_util::*; -use syntax::diagnostic::Emitter; -use syntax::parse::token; -use syntax::print::pprust; - -use program::Program; -use utils::*; - -mod program; -pub mod utils; - -/** - * A structure shared across REPL instances for storing history - * such as statements and view items.
