Splits lines distributed along a horizontal axis. This preprocessor is most useful for typewriter-style documents that use whitespaces for formatting.

Parameters

Note: For additional parameters available for this method, see Global parameters for methods. The following table shows parameters most relevant to or specific to this method.

key	value	description
type (required)	`splitLines`	splits lines distributed along a horizontal axis.
minSpaces (required)	number	The number of consecutive whitespace characters (` `) at or above which to split lines.
separator	string	Modifies the Min Spaces parameter to split on the specified character, for example "-", instead of the default whitespace character. For example, if you specify `"-"` for this parameter and `2` for the Min Spaces parameter, then Sensible splits lines when it finds `--`.

Examples

The following example shows solving undersplit lines in a "typewritten" style document. The Split Lines preprocessor preserves columns and rows in this document.

PROBLEM

Without the Split Lines preprocessor, Sensible merges the lines too aggressively:
