Slow performance when showing long logs

[cibersheep]

When viewing long logs TextEdit performances is slow. Two ways of handling this might be:

• using ListView:
  • Pro: we could do a better formatting (colors and other text improvements)
  • Con: we lose the option to select text as we do now
  • trimming the logs:
  • Pro: we could trim the logs to the last X lines. Sometimes we don't need the whole log
  • Pro: we keep the editing feature
  • Con: we might need to keep a track of trimmed logs (?) or add a settings on how long should be the trim

I have found that you can append some text to the element.

So, maybe, you could append the lasts strings of the updated file:

• splitting by "\n" and iterating the updated log text, getting last lines until is equal to the last line of the element?

• Even better: keeping track of the last index of the "splited" text? having a last index of x, you could iterate var text = updatedLogText.split("\n") from text[x] to text[text.length] and then x = text.length again for the next update
