Examples

Testing if we have a valid URL

# Create an example of how to test for correctly formed URLs
verbex = Verbex()
tester = (verbex.
            start_of_line().
            find('http').
            maybe('s').
            find('://').
            maybe('www.').
            anything_but(' ').
            end_of_line()
)

# Create an example URL
test_url = "https://www.google.com"

# Test if the URL is valid
if re.match(test_url.regex,test_url):
    print("Valid URL")

# Print the generated regex
print(tester) # => ^(http)(s)?(\:\/\/)(www\.)?([^\ ]*)$

Replacing strings

# Create a test string
replace_me = "Replace bird with a duck"

# Create an expression that looks for the word "bird"
expression = Verbex().find('bird')

# Compile and use the regular expression using re
import re
regexp = expression.compile()
result_re = regexp.sub('duck', replace_me)
print(result_re)
