This module contains various string utility routines that are uncommonly used in comparison to the ones in strutils.
Procs
func expandTabs(s: string; tabSize: int = 8): string {....raises: [], tags: [].}
-
Expands tab characters in s, replacing them by spaces.
The amount of inserted spaces for each tab character is the difference between the current column number and the next tab position. Tab positions occur every tabSize characters. The column number starts at 0 and is increased with every single character and inserted space, except for newline, which resets the column number back to 0.
Example:
doAssert expandTabs("\t", 4) == " " doAssert expandTabs("\tfoo\t", 4) == " foo " doAssert expandTabs("a\tb\n\txy\t", 3) == "a b\n xy "
Source Edit func partition(s: string; sep: string; right: bool = false): (string, string, string) {....raises: [], tags: [].}
-
Splits the string at the first (if right is false) or last (if right is true) occurrence of sep into a 3-tuple.
Returns a 3-tuple of strings, (beforeSep, sep, afterSep) or (s, "", "") if sep is not found and right is false or ("", "", s) if sep is not found and right is true.

Example:
doAssert partition("foo:bar:baz", ":") == ("foo", ":", "bar:baz") doAssert partition("foo:bar:baz", ":", right = true) == ("foo:bar", ":", "baz") doAssert partition("foobar", ":") == ("foobar", "", "") doAssert partition("foobar", ":", right = true) == ("", "", "foobar")
Source Edit func rpartition(s: string; sep: string): (string, string, string) {....raises: [], tags: [].}
-
Splits the string at the last occurrence of sep into a 3-tuple.
Returns a 3-tuple of strings, (beforeSep, sep, afterSep) or ("", "", s) if sep is not found. This is the same as partition(s, sep, right = true).

doAssert rpartition("foo:bar:baz", ":") == ("foo:bar", ":", "baz") doAssert rpartition("foobar", ":") == ("", "", "foobar")
