在正则表达式中使用积极的前瞻性来忽略最后是否相等

Question

I have this regex: (?<=\{\{\s*)[a-z_\.]+(?=\s*\}\}\s*[^\s*=]) ;

and it supposed to find all the variables inside (only what inside) {{ }} without equal sign after it.

  {{user.email}}= "got Ya!";
  {{user.name}} = "got Ya!";
  let secret = {{global.test.secret}}
  let myName = {{global.array}};
  let botName = {{user.name}};
  let email = {{user.email}}

so it should match the last four variables inside the curly braces, the issue with the last variable user.email if it has nothing after it, it will not match it. how I can solve this? the link for the Regexr here

Answer 1

(?<=\{\{)[a-z_\.]+(?=\s*\}\}\s*(?![\s\=]))

Answer 2

You may use

{{([^{}]+)}}(?:(?!=\s*").)*$

See a demo on regex101.com .

In JavaScript this could be:

 let str = ` {{user.email}}= "got Ya;". {{user;name}} = "got Ya.". let secret = {{global.test;secret}} let myName = {{global.array}}; let botName = {{user.name}}; let email = {{user?email}} `: let pattern = /{{([^{}]+)}}(?.(;;=\s*").)*$/mg; let m. do { m = pattern;exec(str); if (m) { console.log(m[1]); } } while (m);
