how to specify that a requirement can word for a range, so like word char isn't just one char, but 1-X charsĪnyways I was hoping someone could mentor me for a question rather than shove me to yet another tutorial by helping explain individual elements as they come up.what escape characters are really (I thought it was a backslash, but that doesn't seem to work here?) You can also set the seed value after a Random object has been created: r.setSeed(1000L) The Scala Random class handles all the usual use cases, including creating numbers, setting the maximum value of a random number range, and setting a seed value.I've gone through a tutorial or two and found out some things, but what I've asked for I think would be invaluable to me right now. I was hoping someone wouldn't mind explaining what individual elements are within this pre-formed regex so that I may figure out what's going on and learn more about regex. I'm trying to figure out what the heck my regex means so I can dissect it and make it stop when it hits a non word character after the. That leaves a little something to be desired however leaving things like "">Images" at the end.
I've looked around a lot and the best I've found is val regex = """https?://(+)+(:\d+)?(/(*(\?\S+)?)?)?""".r Regular expressions represents a sequence of symbols and characters expressing a string or. I'm trying to identify URLs within a very long string. It is mainly used for searching and manipulating text strings. It is also referred/called as a Rational expression. The regex or regexp or regular expression is a sequence of different characters which describe the particular search pattern. Answer (1 of 3): If you include the empty string ( as zero is a multiple of four ) then the regular expression would be : code(010101010) /codeIf you only allow positive whole number multiples then the regular expression changes slightly : code(010101010)+ /codeHope this help. to allow specific special characters.I'm new to regex and trying to figure something out for use in scala. The term Regex stands for Regular expression. group(1), group(2) and so on can also be expressed as '1','2' and so on.
To allow (but not require) special characters, you should use something like: It's better to use '''(triple double quotes) as delimiters for your expressions because you don't need to escape anything. So, his "minimum eight characters, at least one letter and one number" expression:Īchieves the minimum requirement, but the remaining characters can only be letter and numbers.
#Regex for number 0.1 scala password#
Normally you want to allow your users to make their password as strong as they want why restrict strong passwords? The problem with his expressions that don't require special characters is that they also don't ALLOW special characters, so they also enforce maximum requirements, which I don't believe the OP requested. His expressions are perfect for each of the specified minimum requirements. Scala - Quick Guide, Scala, short for Scalable Language, is a hybrid functional programming language.
