Helm-projectile-ag broken on Windows?

[angrybacon]

Expected behavior

Should update the list of matches for "foo" in my Helm buffer as I progressively type foo.

Actual behavior

Both helm-ag and projectile-ag work as intended however.

Steps to reproduce the problem

(require 'package)
(package-initialize)

Open a project file.

M-x helm-projectile-ag foo

Backtraces if necessary (M-x toggle-debug-on-error)

No error.

Ag had jumped to from v0.29.1.1641 to v2.1.0.1. Went back and helm-projectile-ag now works again
Let me know what more information I can provide to help.

choco uninstall ag
choco install ag --version 0.29.1.1641

helm-projectile-ag just makes use of helm-ag.

Can you check whether helm-ag w/ the newer ag works for you? I'd expect not. If not, you can open an issue there.

[angrybacon]

@xiongtx Like I said, both helm-ag and projectile-ag work as intended.

I cannot reproduce on a Windows 8 machine w/ ag 2.1.0.

Can you upgrade to latest helm-projectile and try again?

[angrybacon]

choco uninstall ag
choco install ag

ag --version

Could this be a Windows 10 specific problem?

I don't have Windows 10, so if someone else (@bbatsov?) can reproduce, that'd be great.

@angrybacon If you've Windows 8, can you confirm that this works on Windows 8?

[angrybacon]

@xiongtx Unfortunately, I don't have access to Windows 8 easily.

[rgoulter]

Found this issue through Google.
I'm also using Windows 10.

helm-ag works.
(running M-x helm-ag will prompt for pattern, and helm's buffer will update when updating the pattern)

(currently the latest commit on master)

angrybacon's workaround of "install an older version of ag" worked for me.
