Generic stripping on ranges: strip
Example
import std .uni : lineSep, paraSep;
assert(strip(" hello world ") ==
"hello world");
assert(strip("\n\t\v\rhello world\n\t\v\r") ==
"hello world");
assert(strip("hello world") ==
"hello world");
assert(strip([lineSep] ~ "hello world" ~ [lineSep]) ==
"hello world");
assert(strip([paraSep] ~ "hello world" ~ [paraSep]) ==
"hello world");
Example
assert(strip(" hello world ", "x") ==
" hello world ");
assert(strip(" hello world ", " ") ==
"hello world");
assert(strip(" xyxyhello worldxyxy ", "xy ") ==
"hello world");
writeln(strip("\u2020hello\u2020"w, "\u2020"w)); // "hello"w
writeln(strip("\U00010001hello\U00010001"d, "\U00010001"d)); // "hello"d
writeln(strip(" hello ", "")); // " hello "
Example
writeln(strip("xxhelloyy", "x", "y")); // "hello"
assert(strip(" xyxyhello worldxyxyzz ", "xy ", "xyz ") ==
"hello world");
writeln(strip("\u2020hello\u2028"w, "\u2020"w, "\u2028"w)); // "hello"w
assert(strip("\U00010001hello\U00010002"d, "\U00010001"d, "\U00010002"d) ==
