Library "logger"

Overview
A dual logging library for developers. Tradingview lacks logging capability. This library provides logging while developing your scripts and is to be used by developers when developing and debugging their scripts.
Using this library would potentially slow down you scripts. Hence, use this for debugging only. Once your code is as you would like it to be, remove the logging code.

◼︎ Usage (Console):
Console = A sleek single cell logging with a limit of 4096 characters. When you dont need a large logging capability.


◼︎ Usage (Logx):
Logx = Multiple columns logging with a limit of 4096 characters each message. When you need to log large number of messages.


◼︎ Fields (with default settings)
  ▶︎ IsConsole         = True  Log will act as Console if true, otherwise it will act as Logx
  
  ▶︎ ShowHeader        = True  (Log only) Will show a header at top or bottom of logx.
  ▶︎ HeaderAtTop        = True  (Log only) Will show the header at the top, or bottom if false, if ShowHeader is true.
  ▶︎ ShowStatusBar       = True  Will show a status bar at the bottom
  ▶︎ StatusBarAtBottom     = True  Will show the status bar at the bottom, or top if false, if ShowHeader is true.

  ▶︎ ShowDateTime       = True  Logx will show column for Date/Time passed with the logged message logged. Console will add Date/Time at the front of logged messages
  ▶︎ ShowLogLevels       = True  Logx will show column for Log levels corresponding to error codes. Console will log levels in the status bar

v3

Demonstration of the library usage via this script =>
libhs.log.DEMO

When you see how it works, then you can look up the library code for functions/methods or just simply call one of the 4 documentation functions listed below.

Changes:
- Better error checking. Should not see anymore errors on usage now. I am using this for my debugging my other code developments and that has helped to thrash out issues from v1 and v2.
- Improvements to async logging
- Addition of individual coloring of cells when logging.
- Ability to revert logged messages (undoing messages)
- New overloaded functions for letting all types of calls to log/alog/page/logX/undo/undoQ/undoX
- Massive improvements to documentation.

Known Issues/Limitation:
- When using this library your script will compile for lot longer and may slow down as well. This should be ok, as long as you debug parts of code and move them to a final working version of the script. This library is just for debugging your code.
- The library itself is reaching the max compiled code limits on my development version.

Next Update:
- I will look to see if I can implement independent queues (logging 6 queues separately, not asynchronously.).
