line-stream

split/binary-split but lines contain byte offset in the source stream and gives access to last line fragment

• this module leaves the delimiter on the resulting buffer.
• all values are cast to buffers and emitted as buffers.
• this module is just as fast as binary-split.

var linestream = require('line-stream');
var s = linestream();

s.on('data',function(line){
  console.log('line of data ',line+'');
  console.log('i come from ',line.start,'byte offset in the file')
})

fs.createReadStream(somefile).pipe(s);

api

var linestream = require('line-stream');

• transform stream (through2)

linestream(delimiter) || linestream({delimiter:os.EOL,start:0})

• returns transform stream.
• options
  • delimiter, defaults to os.EOL but can be anything
  • start, defaults to 0. this is an offset applied to the start property of each line's "line.start" property. just helpful.

stream

• properties
  • stream.fragment, at any time this property contains the fragment of the last incomplete line or an empty buffer.
• events, in addition to standard stream events this module also emits
  • fragment, emits before end if there is a line fragment in the fragment property.
