Invalid Expression in Line 31

[yths]

Something is wrong with this line:
let s:ackprg_version = eval(matchstr(system(g:ackprg . " --version"), '[0-9.]+'))

When I start vim it tells me, that in line 31 (the one above) is an invalid expression.

I have the same error on my system

I'm still seeing this issue even after 08a3494

[bitboxer]

It's fixed for me.

@azakus which version of ack and vim are you using? and did you change your g:ackprg?

[dfreedm]

ack 2.12, vim 7.4 patches 1-135

I have not set g:ackprg

[kassio]

@azakus sorry didn't ask it in first time, but which OS are you using and how is set your wildignore?

[dfreedm]

OS: Arch x86_64
wildignore = *.o, *~

Adding: let g:ack_wildignore = 0 to my .vimrc did make the error go away but I'm not sure what that does.

[kassio]

I'm starting to think that was not a good idea try to respect wildignore with the plugin:

1. It is not a simple parse the plugin has to do, and it impedes to use ag as search tool.
2. You can set the ignore settings on your ~/.ackrc

I'll remove this feature for now, and we can try use it in future.
