Make text lower case inside of curly braces in VIM

I have a number of email templates for use inside mailchimp that are currently using standard merge tags, ala *|SUBJECT|*. I want to convert these templates for Handlebars usage.

I can easily use %sno/*|/{{ and %sno/|*\}} to swap the tag delimiters, but this leaves me with all-caps names, like {{SUBJECT}}. Is there a good command for forcing lowercase inside of double curly braces in VIM so I don't have to hunt down and change every single variable?

Quicker problem description:

I have a lot of situations like this in an email template:

<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>*|SUBJECT|*</title>

I instead want this:

<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>{{subject}}</title>

What are the VIM commands I need to get there?

Solution

  • How about doing all that in one go?

    :%s/\*|\(.\{-}\)|\*/{{\L\1\E}}/g
