chomp

If str ends with delimiter, then str is returned without delimiter on its end. If it str does not end with delimiter, then it is returned unchanged.

If no delimiter is given, then one trailing '\r', '\n', "\r\n", '\f', '\v', std.uni.lineSep, std.uni.paraSep, or std.uni.nelSep is removed from the end of str. If str does not end with any of those characters, then it is returned unchanged.

Examples

import std.uni : lineSep, paraSep, nelSep;
import std.utf : decode;
assert(chomp(" hello world  \n\r") == " hello world  \n");
assert(chomp(" hello world  \r\n") == " hello world  ");
assert(chomp(" hello world  \f") == " hello world  ");
assert(chomp(" hello world  \v") == " hello world  ");
assert(chomp(" hello world  \n\n") == " hello world  \n");
assert(chomp(" hello world  \n\n ") == " hello world  \n\n ");
assert(chomp(" hello world  \n\n" ~ [lineSep]) == " hello world  \n\n");
assert(chomp(" hello world  \n\n" ~ [paraSep]) == " hello world  \n\n");
assert(chomp(" hello world  \n\n" ~ [ nelSep]) == " hello world  \n\n");
assert(chomp(" hello world ") == " hello world ");
assert(chomp(" hello world") == " hello world");
assert(chomp("") == "");

assert(chomp(" hello world", "orld") == " hello w");
assert(chomp(" hello world", " he") == " hello world");
assert(chomp("", "hello") == "");

// Don't decode pointlessly
assert(chomp("hello\xFE", "\r") == "hello\xFE");
