compare files of different length

[joh-klein]

I really like this package! Thanks for your hard work!

What I wish it could do: when one file is longer (has more lines) than the other, that it doesn't stop but append all the missing lines to the output (either as being new (+) or old (-) )

You can use compared event to detect end of file, see parameters here: https://github.com/niiknow/text-file-diff/blob/master/src/index.ts#L104

End of file property, ref: https://github.com/niiknow/text-file-diff/blob/master/src/index.ts#L15

const lfd = new TextFileDiff({
  skipHeader: argv.skipHeader
});

lfd.on('compared', (line1, line2, cmpar, lineReader1, lineReader2) => {
  if (lineReader1.eof > -1 || lineReader2.eof > -1) {
      // do something such as exit program, etc...
  }
});

The plus (+) and minus (-) events also receive lineReader1 and lineReader2 as 2nd and 3rd parameter so you can also detect end of file within those events, ref: https://github.com/niiknow/text-file-diff/blob/master/src/index.ts#L111

@noogen am kinda in the same boat, can u plz elaborate how to actually use that ?

for example, lets say the first-stream lines count is 40, while the second stream lines count is 50, how do u get the diff ?

@ctf0 I don't understand, it already doing that. Have you tried it? Elaborate more on what are you really expect it to do?

Even better, look at the unit tests. Fork, upload your 2 files, write unit tests and elaborate on what you're expecting it to do. Do the real Test Driven Development (TDD) approach.
