clawbang
A command line interface meant to bridge the gap between Rust and shell scripting. Intended for use with HEREDOCs and shebangs:
$ clawbang <<EOF
fn main() {
println!("hello world!")
}
EOF
Or as a binary executable file:
#!/usr/bin/env clawbang
fn main() {
println!("hello world!")
}
performance
Clawbang takes the file input, hashes it, and then looks for a cached compiled copy. If no copy is present, Clawbang compiles your code and caches it by that hash for later lookup.
If your program failed to compile, those error messages are cached as well.
