Creating a design that verifies every initial letter is capitalized

Looking for an Angular pattern that specifically checks if the first letter of each word is capitalized. To achieve this, I have implemented the following pattern:

pattern ="^([A-Z][a-z]*((\\s[A-Za-z])?[a-z]*)*)$"

1- This pattern only works for the first letter of each word.

2- In cases where there are multiple failures, the focus is on checking the first letter of the strings.

Answer №1

One possible solution is to implement the following regular expression pattern:

^(\b[A-Z]\w*\s*)+$

Answer №2

Check out this regular expression pattern for matching uppercase words with hyphens:

/([A-Z][\w-]*(\s+[A-Z][\w-]*)+)/

You can find more information at this Stack Overflow post

Answer №3

It seems that your current pattern is only effective for the first letter of the first word, since it requires an uppercase A-Z at the beginning. However, as you pointed out, the repeated group starting with \s[A-Za-z] can also match lowercase letters.

Keep in mind that \s includes newlines as well. To exclude them, consider using a character class like [ \t] to match spaces or tabs instead.

To ensure consistency, try matching both the start and the repeated group with capitalized letters (A-Z). For word matches, consider using \w to represent word characters.

^[A-Z]\w*(?:[\t ]+[A-Z]\w*)*$

See regex demo here.
