Rust helper scripts (deprecated)

rustx

• rustx: Inspired by runhaskell, this script compiles a rust file and runs it immediately. (This can be launched from a source file via #!/usr/bin/env rustx, too.)
• rustt: This script compiles a rust file's tests and runs them.
• _rustx: This is a dummy Rust program...

At the moment, this git repo doesn't seem to work quite right with rustpkg, but I'll sort that out soon enough!

rustx's Issues

Fix syntax for test code

For example this code doesn't compile with rustt or with manual options to rustc:

//#!/usr/bin/env rustx

fn main () {
   io::println("Hello!");
}

#[test]
fn test () {
   assert 2 + 2 == 4;
}

In action:

$ rustt _rustx.rs
_rustx.rs:1:0: 1:0 error: unresolved modulename: std
_rustx.rs:1 
            ^
_rustx.rs:1:0: 1:0 error: unresolved modulename: std
_rustx.rs:1 
            ^
error: aborting due to previous errors

This is very uncool.

New temp files created on every run

Each time rustx executes, it creates a new temp file which is never removed.

Shebangs

How can we modify rustx to work in shebangs like Perl, Python, Ruby, Lua, etc.?

hello.rs:

#!/usr/bin/env rustx

use std;

fn main() {
    log "Hello World!";
}

expected output:

$ chmod a+x hello.rs
$ ./hello.rs
Hello World!

actual output:

$ chmod a+x hello.rs
$ ./hello.rs
Usage: rustx rust-source-file.rs
