split-stream-lines-preserve-eol-pmb

Split a stream into lines that include their line terminator if they had one.

API

This module exports one function:

makeLineSplitter(opt)

Returns a duplex stream that splits the input by lines.

opt is an optional options object that supports these keys:

• sep: RegExp for what you consider a line terminator. Default: /(\n)/
• nEolGroups: The number of match groups in sep. Default: 1
• discardRemainder: Boolean, whether to silently discard the last line if it was not properly terminated. Default: false

These experimental options are planned but do not work reliably yet:

• throughOpt: Options to pass through to through2. Default: empty object.
• obj: A shortcut for enabling objectMode in throughOpt. Boolean. Default: false
• combine: A function that merges the line with the match group(s) of its terminator. It will be called with one argument, a flat array of all these parts. Can also be false to pass on said array, auto-enabling the obj option. Defaults to a function that can concat either buffers and strings.

Known issues

• Needs more/better tests and docs.
