Wireshark · Wireshark-dev: Re: [Wireshark-dev] Capture filter syntax check - why no check before starting a session?

[Jaap Keuter <jaap.keuter@xxxxxxxxx>]

Hi,

I've been toying with the idea of adding a precompile option button to  
the capture dialog. When pressing that a popup would show you the BPF  
code (like tcpdump -d) and a result of processing the capture filter.

Maybe you can file an enhancement bug?

Thanks,
Jaap
