For earlier discussion, see rust-lang/rust#14223
This issue was labelled with: A-libs in the Rust repository
Sample program:
extern crate getopts; use getopts::{optopt,optflagopt,getopts}; use std::os; fn main() { let args = os::args(); let opts = [optopt( "o", "output", "set output file name", "NAME"), optflagopt("a", "attrib", "set attribute", "KEY=VALUE")]; let matches = match getopts(args.tail(), opts) { Ok(m) => { m } Err(f) => { fail!(f.to_err_msg()) } }; let output = matches.opt_str("o"); let keyval = matches.opt_str("a"); println!("output: {}", output); println!("attrib: {}", keyval); }
Here is a transcript illustrating some interesting invocations
% rustc /tmp/g.rs % ./g --output=hm output: Some(hm) attrib: None % ./g --attrib output: None attrib: None % ./g --attrib hi output: None attrib: Some(hi) % ./g --attrib hi=world output: None attrib: Some(hi=world) % ./g -a=hi=world output: None attrib: Some(=hi=world) % ./g -a hi=world output: None attrib: Some(hi=world) % ./g --attrib=hi=world output: None attrib: Some(hi) %
I think that --attrib hi=world and --attrib=hi=world should be treated as equivalent inputs.
--attrib hi=world
--attrib=hi=world
From skimming getopts, this should be relatively easy to fix by replacing the call to split('=') with splitn('=', 1).
split('=')
splitn('=', 1)
The text was updated successfully, but these errors were encountered:
handle '=' in arguments more nicely

Now "--arg=A=B" and "--arg A=B" are equivalent. Fixes rust-lang#14.
