Elixir Regular Expressions made easy. Ported from the JavaScript version VerbalExpressions.
Include the VerbalExpressions module (and alias it, if you want). Then simply check out the Examples and documentation to get started. It's easy :)
Here's a couple of simple examples to give an idea of how VerbalExpressions works:
# Create an example of how to test for correctly formed URLs
alias VerbalExpressions, as: VerEx
tester = VerEx.startOfLine()
|> VerEx.then("http")
|> VerEx.maybe("s")
|> VerEx.then("://")
|> VerEx.maybe("www")
|> VerEx.anythingBut(" ")
|> VerEx.endOfLine()
testMe = "https://www.google.com"
result = tester |> VerEx.match?(testMe)
if result do
IO.puts "Valid URL :)"
else
IO.puts "Invalid URL :("
end# Create a test string
replaceMe = "Replace bird with a duck"
# Create an expression that seeks for word "bird"
expression = VerEx.find "bird"
# Execute the expression like a normal RegExp object
result = expression |> VerEx.replace replaceMe, "duck"
IO.puts result # Outputs "Replace duck with a duck"result = VerEx.find("red") |> VerEx.replace "We have a red house", "blue"
IO.puts result # Outputs "We have a blue house"The original version of VerbalExpressions uses method chaining. This version of
verbal expressions in Elixir does not only support the (nicer) |>-based
chaining, but also has a record-based version for method-chaining support.
Here is the above string replace example using method chaining:
v = VerbalExpressionRecord.new
result = v.find("red").replace("We have a red house", "blue")
IO.puts result # Outputs "We have a blue house"You can find the API documentation on it's own page.

Thank you to @jehna for coming up with the awesome original idea!
