Description

Now we add [] only to variables within a string & only to variables which are not process environment variables (those that don't start with process.env.).

I also added this feature to the CLI.

So this is a good start, but I don't really like the regex.

Your regex did affect variables that either did include a dot or were escaped using a \.

So i extended your Regex to: /(?<!\\)\{\{(?!process\.env\.\w+)(.*\..*)\}\}/g on regexr: https://regexr.com/7ql6d

Small regex dissection:

• (?<!\\) Negative look behind to ignore escaped variables
• (?!process\.env\.\w+) negative look ahead to unmatch process.env.*
• (.*\..*) Match anything that includes a dot

After I saw Martin's reply here: #1410 (reply in thread) I thought maybe we can use the missingHelper here, but apparently the missingHelper does not work with nested properties: handlebars-lang/handlebars.js#1435.

Thanks for improving the regex @Its-treason, I've changed it to yours + added a test case for escaped vars.

Unfortunately, I won't have time anymore to contribute to Bruno (and subsequently follow up on this PR in case of issues), so I won't be able to look into a better solution using Handlebars' features/options. I've allowed edits for maintainers so feel free to take over this PR or close it as you see fit 👍
