borrow_visualizer_prototype

No longer maintained

This is a prototype, and one that will only be used temporarily. The long term plan is to integrate the ideas learned here into https://github.com/rust-lang-nursery/rls

Dependencies:

• https://github.com/Nashenas88/rust/tree/borrow_visualizer
• rustup (optional but makes things easier. Also, there are no instructions for doing this without rustup ;)

To run, perform the following actions:

• First compile https://github.com/Nashenas88/rust/tree/borrow_visualizer with python2.7 x.py build --stage 2
• Wait a long time (~1 and a half hours on my machine the first run)
• Use rustup to create a new toolchain with rustup toolchain link bv-rust <path-to-rust-src>/build/<host>/stage2 where host might be something like x86_64_apple_darwin
• Make sure you replace the above params in "<>" with the values for your system
• In the folder for this repo then type rustup override set bv-rust (you can choose another name besides bv-rust if you like, just make sure it matches the steps above)
• Run cargo build
• Run with target/debug/borrow_bounds line data/lifetime8.rs 13 12 data/lifetime8.rs --sysroot=$(rustc --print sysroot)

The current output should look like this:

[{"kind":"mut", "start":"212", "end":"218"},{"kind":"imm", "start":"233", "end":"239"}]

Type target/debug/borrow_bound help to see usage instructions.
