const regex = /^(?:remind me ).*? (to|that|about|its|it's)? ?(.*)$/gm;
// Alternative syntax using RegExp constructor
// const regex = new RegExp('^(?:remind me ).*? (to|that|about|its|it\'s)? ?(.*)$', 'gm')
const str = `remind me in 24 hours test
remind me in 24 hours to test
remind me to test
E.g. These strings would work with your current pattern
two spaces after 'remind me' where the group fits in:
^(?:remind me ).*? (to....
^ ^
remind me to test
remind me blabla to test
one or three or more, no:
remind me to test
remind me to test
remind me bla bla to test
`;
// Reset `lastIndex` if this regex is defined globally
// regex.lastIndex = 0;
let m;
while ((m = regex.exec(str)) !== null) {
// This is necessary to avoid infinite loops with zero-width matches
if (m.index === regex.lastIndex) {
regex.lastIndex++;
}
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
});
}
