how to get the file extension in pike

Question

I'm working on a program in pike and looking for a method like the endswith() in python- a method that gives me the extension of a given file. Can someone help me with that? thank you

Answer 1

Python's endswith() is something like Pike's has_suffix(string s, string suffix):

has_suffix("index.html", ".html");

Reference: http://pike.lysator.liu.se/generated/manual/modref/ex/predef_3A_3A/has_suffix.html

Answer 2

extract the end of the string, and compare it with the desired extension:

"hello.html"[<4..] == ".html"

(<4 counts from the end of the string/array)

Answer 3

If you want to see what the extension of a file is, just find the last dot and get the substring after it, e.g. (str/".")[-1]

If you just want to check if the file is of a certain extension, using has_suffix() is a good way, e.g. has_suffix(str, ".html")
