Unable to compile

[sirideain]

I get these errors whenever I try to compile any version after 0.11.0. I tried with Rust 1.1.0, 1.2.0, and 1.3.0.

After some more trial and error, I was able to get it to compile if I removed the default-features line below.

[dependencies.clap]
version = "*"
default-features = false
features = [ "suggestions" ] # Color can't be used with Windows as it throws odd characters in there

[kbknapp]

Thanks for taking the time to file this! I'll start looking into it!

I'll post back here with anything I find.

[kbknapp]

Also, I forgot to ask, which version of Rust are you using? (rustc -V should spit it out).

[sirideain]

I tried it with three versions of Rust.

rustc 1.1.0 (35ceea399 2015-06-19)
rustc 1.2.0-beta.2 (c8bab9d06 2015-07-09)
rustc 1.3.0-nightly (e4e93196e 2015-07-14)

[kbknapp]

Ok, good to know, thanks! :)

I may also just disable colorized output on windows, because if it just spits out crazy characters no reason to make windows devs have to manually exclude the dep.

[sirideain]

Here is what the output looks like on Windows.

←[1;31merror:←[0m The argument '←[33m-a←[0m' isn't valid

[kbknapp]

Yep, I was able to reproduce this error, as well as the wonky colorized output. This should be an easy fix, and I should have a working 1.1.3 up for you soon ;)

[kbknapp]

Once #164 passes Travis I'll merge into master and publish v1.1.3 on crates.io

Also note with that PR, you no longer need to specify

default-features = false
features = ["suggestions"]

It will still compile ansi_term but it won't use it. Now if you want to keep your dep list short, or just don't want to compile ansi_term you can still turn off the "color" feature like before ;)

[kbknapp]

This issue has been fixed with v1.1.3 on crates.io or master here. @classicboss302 please let me know if you have any further issues! And thanks again for taking to time to report this and assist! 👍
