Remove everything except characters between '<' & '>,' in Vim — extract email addresses from Gmail “To” field

问题

I have a comma-delimited list of email addresses with each actual address prepended by the contact's name (from Gmail). Here's an example:

Fred Flintstone <fred@flintstone.org>, Wilma Flintstone <wilma@flintstone.org>, Barney Rubble <barney@rubble.org>, Bamm-Bamm Rubble <bammbamm@rubble.org>,

converts to:

fred@flintstone.org, wilma@flintstone.org, barney@rubble.org, bammbamm@rubble.org,

Background info: I am trying to paste the list of contacts into a webex invite, which can only accept email addresses.

Remove everything except regex match in Vim is related, but all the email addresses are on one line in this case.

回答1:

Have you tried?

:s/.\{-}\%(\(,\s*\)\|<\(.\{-}\)>\)/\1\2/g

The following will also work:

:s/.*/\=join(map(split(submatch(0), ','), "matchstr(v:val, '<\\zs.*\\ze>')"), ', ')

回答2:

with awk

    echo "Fred Flintstone <fred@flintstone.org>, Wilma Flintstone <wilma@flintstone.org>, Barney Rubble <barney@rubble.org>, Bamm-Bamm Rubble <bammbamm@rubble.org>
"|awk -F'<|>' '{for (i=1;i<=NF;i++)printf (i%2==0)?$i",":""}'

or in VIM

:%s/,/\r/g
:%s/.*<\(.*\)>/\1/g

回答3:

Could you not put it into Excel, then split the data on the comma and then and then do a find and replace to get rid of the angel bracket

Unless you are using some code to do it this would be the easiest unless you have 100,000's of thousand addresses
