trait Filters extends AnyRef

A collection of useful string filters. They are particularly intended to be filters for pretty-printer output so that the output can be tailored for a restricted setting in which it will be put. E.g., a program might be pretty-printed to show in a GUI window of a particular size, or lines indented greater than a certain amount might be omitted to show an overview.

  11. def indentOf(s: String): Int

    Return the indentation of a line, i.e., the number of spaces that appear before the first non-space character.

  12. def indentedEllipsis(n: Int, s: String): String

    A replacement function that when given an integer n returns the string "..." preceded by n spaces.

    A replacement function that when given an integer n returns the string "..." preceded by n spaces. The string argument s is ignored.

  14. def keepMaxChars(n: Int)(s: String): String

    A filter that limits the string s to at most n characters.

  15. def keepMaxIndent(n: Int, s: String, mkrepl: (Int, String) ⇒ String = indentedEllipsis): String

    A filter that replaces runs of lines that have an indentation level of at least n spaces.

    A filter that replaces runs of lines that have an indentation level of at least n spaces. A run of replaced lines will be replaced by the result of a call mkrepl (n, l) where l is the first line of the run. By default, mkrepl is indentedEllipsis.

  16. def keepMaxLines(n: Int)(s: String): String

    A filter that limits the string s to at most n completed lines.

    A filter that limits the string s to at most n completed lines. The final end of line is included.

  17. def keepMaxWords(n: Int)(s: String): String

    A filter that limits the string s to at most n words.

    A filter that limits the string s to at most n words. A word is one or more consecutive non-whitespace characters. The whitespace after the last word (if any) is not included.
