regex v0.1.28 : compilation error about regex HOT 6 CLOSED

Which project? It looks like it's enabling the pattern feature, which doesn't work on beta because it is unstable.

This is a personal project which you can find on github : https://github.com/gbersac/computorv1-42

Am I suppose to use nightly ? What if I want to stay with beta ?

You can't use beta and enable unstable features: https://github.com/gbersac/computorv1-42/blob/master/src/main.rs#L1-L3 If you want to use unstable features, you must use the nightly.

One of the unstable features you're using is regex_macros, which only works on the nightly. It also enables the pattern feature, which is why you're getting this error. (pattern only works on nightly too.)

If you want to work on beta, you'll need to remove all uses of #![feature(...)] and change your dependencies to just regex (no regex_macros).

You may find this useful :-) https://github.com/docopt/docopt.rs/blob/master/src/lib.rs#L231-L233

Just note that that won't give you compile time errors, obviously.

Nor a nice performance boost!
