Logger Library For Pinescript (Logging and Debugging)Library "LoggerLib"
This is a logging library for Pinescript. It is aimed to help developers testing and debugging scripts with a simple to use logger function.
Pinescript lacks a native logging implementation. This library would be helpful to mitigate this insufficiency.
This library uses table to print outputs into its view. It is simple, customizable and robust.
You can start using it's .log() method just like any other logging method in other languages.
//////////////////
USAGE
//////////////////
-- Recommended: Please Read The Documentation From Source Code Below. It Is Much More Readable There And Will Be Updated Along With Newer Versions. --
Importing the Library
---------------------
import paragjyoti2012/LoggerLib/ as Logger
.init() : Initializes the library and returns the logger pointer. (Later will be used as a function parameter)
.initTable: Initializes the Table View for the Logger and returns the table id. (Later will be used as a function parameter)
parameters:
logger: The logger pointer got from .init()
max_rows_count: Number of Rows to display in the Logger Table (default is 10)
offset: The offset value for the rows (Used for scrolling the view)
position: Position of the Table View
Values could be:
left
right
top-right
(default is left)
size: Font Size of content
Values could be:
small
normal
large
(default is small)
hide_date: Whether to hide the Date/Time column in the Logger (default is false)
returns: Table
example usage of .initTable()
import paragjyoti2012/LoggerLib/1 as Logger
var logger=Logger.init()
var logTable=Logger.initTable(logger, max_rows_count=20, offset=0, position="top-right")
-------------------
LOGGING
-------------------
.log() : Logging Method
params: (string message, |string| logger, table table_id, string type="message")
logger: pass the logger pointer from .init()
table_id: pass the table pointer from .initTable()
message: The message to log
type: Type of the log message
Values could be:
message
warning
error
info
success
(default is message)
returns: void
///////////////////////////////////////
Full Boilerplate For Using In Indicator

rsi=ta.rsi(close,14)
|macd,signal,hist|=ta.macd(close,12,26,9)
if(ta.crossunder(close,34000))
Logger.log("Dropped Below 34000",logger,logTable,"warning")
if(ta.crossunder(close,35000))
Logger.log("Dropped Below 35000",logger,logTable)
if(ta.crossover(close,38000))
Logger.log("Crossed 38000",logger,logTable,"info")
if(ta.crossunder(rsi,20))
Logger.log("RSI Below 20",logger,logTable,"error")
if(ta.crossover(macd,signal))
Logger.log("Macd Crossed Over Signal",logger,logTable)
if(ta.crossover(rsi,80))
Logger.log("RSI Above 80",logger,logTable,"success")
////////////////////////////
// For Scrolling the Table View
////////////////////////////
There is a subtle way of achieving nice scrolling behaviour for the Table view. Open the input properties panel for the table/indicator. Focus on the input field for "Offset", once it's focused, you could use your mouse scroll wheel to increment/decrement the offset values; It will smoothly scroll the Logger Table Rows as well.

globalCurrently in PineScript you cannot modify global variables in functions because of scope limitations.
One way to work around that is to use arrays.
This Library simplifies the use of arrays as global variables to make your code look cleaner.
If you're coming from other programming languages, I'm sure you will come across this issue in your PineScript journey at some point.
------------------------------------
The code below will throw an error that says: Cannot modify global variable 'price' in function.
var price = 0.0
function() =>
price := 5.5
------------------------------------
To work around that you can do:
var price = array.new_float(1, 0.0)
function() =>
array.set(price, 0, 5.5)
But that code does not spark joy.
------------------------------------
So I bring to you the global library:
import marspumpkin/global/1
var price = global.init(0.0)
function() =>
global.set(price, 5.5)
Debug_Window_LibraryLibrary "Debug_Window_Library"
Provides a framework for logging debug information to a window on the chart.

txt : - this is the text to be appended to the window
maxLines : - this is the size of the window in lines.
Returns: nothing
The example above shows the close value for the last 10 bars.
Here's the code.
//@version=5
indicator("Debug Library test Script", overlay=true)
import sp2432/Debug_Window_Library/1 as dbg
// add some text to the debug window
dbg .consoleWrite( str .tostring(close), 10)

Parameters:
msg : message to be logged on console
Returns: nothing
tickFormat() Create a string template to restrict stop-loss, take-profit level precision to ticks.

benchLibrary "bench"
A simple banchmark library to analyse script performance and bottlenecks.
Very useful if you are developing an overly complex application in Pine Script, or trying to optimise a library / function / algorithm...
Supports artificial looping benchmarks (of fast functions)
Supports integrated linear benchmarks (of expensive scripts)
One important thing to note is that the Pine Script compiler will completely ignore any calculations that do not eventually produce chart output. Therefore, if you are performing an artificial benchmark you will need to use the bench.reference(value) function to ensure the calculations are executed.
Please check the examples towards the bottom of the script.
Quick Reference

debuggerDEBUGGER is a library to help print debug messages to a console.
This library provides an easy-to-use interface to print your debugging messages to a console in the chart. Special attention has been given to printing series and arrays easily.
A debugger is a valuable tool when working on scripts and getting into trouble. Unfortunately, TradingView does not provide an interactive debugger, and does not provide a console to use the oldest trick in the debugging book: print statements. This library provides you with the latter tool, print statements.
As a bonus, the library also provides a way to show labels in the chart next to the pricing action.
For more information and examples of usage, check the description in the header comments.
logLibrary "log"
A Library to log and display messages in a table, with different colours.
The log consists of 3 columns:
Bar Index / Message / Log
Credits
QuantNomad - for his idea on logging messages as Error/Warnings and displaying the color based on the type of the message
setHeader(_t, _location, _header1, _header2, _header3, _halign, _valign, _size) Sets the header for the table to be used for displaying the logs.
Parameters:
_t : table, table to be used for printing
_location : string, Location of the table.
_header1 : string, the name to put into the Index Queue Header. Default is 'Bar #'
_header2 : string, the name to put into the Message Queue Header. Default is 'Message'
_header3 : string, the name to put into the Log Queue Header. Default is 'Log'
_halign : string, the horizontal alignment of header. Options - Left/Right/Center
_valign : string, the vertical alignment of header. Options - Top/Bottom/Center
_size : string, the size of text of header. Options - Tiny/Small/Normal/Large/Huge/Auto
Returns: Void
initHeader(_location, _rows, _header1, _header2, _header3, _halign, _valign, _size, _frameBorder, _cellBorder) Creates the table for logging.
3 columns will be displayed.
Bar Index Q / Message Q / Log Q
Parameters:
_location : string, Location of the table.
_rows : int, table size, excluding the header. Default value is 40.
_header1 : string, the name to put into the Index Queue Header. Default is 'Bar #'
_header2 : string, the name to put into the Message Queue Header. Default is 'Message'
_header3 : string, the name to put into the Log Queue Header. Default is 'Log'
_halign : string, the horizontal alignment of header. Options - Left/Right/Center
_valign : string, the vertical alignment of header. Options - Top/Bottom/Center
_size : string, the size of text of header. Options - Tiny/Small/Normal/Large/Huge/Auto
_frameBorder : int, table Frame BorderWidth. Default value is 1.
_cellBorder : int, table Cell Borders Width, Default value is 2.
Returns: table
init(_rows) Initiate array variables for logging.
Parameters:
_rows : int, table size, excluding the header. Default value is 40.
Returns: tuple, arrays - > error code Q, bar_index Q, Message Q, Log Q
log(_ec, _idx, _1, _2, _m1, _m2, _code, _prefix, _suffix) logs a message to logging queue.
Parameters:
_ec : int , Error/Codes (1-7) for colouring.
Default Colour Code is 1 - Gray, 2 - Orange, 3 - Red, 4 - Blue, 5 - Green, 6 - Cream, 7 - Offwhite
_idx : int , bar index Q. The index of current bar is logged automatically
you can add before and after this index value, whatever you choose to, via the _prefix and _suffix variables.
_1 : string , Message Q.
_2 : string , Log Q
_m1 : string, message needed to be logged to Message Q
_m2 : string, detailed log needed to be logged to Log Q
_code : int, Error/Code to be assigned. Default code is 1.
_prefix : string, prefix to Bar State Q message
_suffix : string, suffix to Bar State Q message
Order of logging would be Bar Index Q / Message Q / Log Q
Returns: void
resize(_ec, _idx, _1, _2, _rows) Resizes the all messaging queues.
a resize will delete the existing table, so a new header/table has to be initiated after the resize.

logLibrary "log"
Logging library for easily displaying debug, info, warn, error and critical messages.
No real need to explain why you might want to use this library! I'm sure you've all experienced the frustration of trying to understand the data state of your scripts... so, enjoy! More on it's way...
(Don't forget to check the helpers in the script and the useful tips below)
Some Useful Tips
By default the log console persists between bars (for history) and bars and ticks (for realtime).
Sometimes it is useful to clear the log after each candle or tick (assuming we are using the above helpers):
```
log_print(clear = true) // starts afresh on every bar and tick (excludes historical bars but good realtime tick analysis)
log_print(clear = barstate.isnew) // clears the log at the start of each bar (again, excludes historical but good realtime candle analysis)
```
It is also useful to be able to selectively understand the state of data at specific points or times within a script:
```
if log.once()
debug('useful variable', my_var) // this log only gets written once, upon first execution of this statement
if log.only(5)
debug3(a, b, c) // these variables are only logged the first five times this statement is executed
log_print(clear = false) // clear must be false and you should not write other logs on every bar, or the above will be lost
```
Final tip. If you want to view ONLY log entries of a particular level, then negate the constant:
```
log_print(level = -LOG_DEBUG)
```

assertLibrary "assert"
Production ready assertions and auto-reporting for unit testing pine scripts.
This library was born from the need to maintain production level stability and catch regressions / bugs early and fast. I hope this help you trust your pine scripts too. More libraries and tools on their way... please follow for more.
Please see the script for helpers to copy into your own scripts as well as examples at the bottom of the library unit testing itself.

Simple debug functionSimple method I used to debug problem in my script.
For loop generates 5 numbers from the given depth. At present, depth is 9
Rules for generating the combinations are as follows:
First number is always 1
Two even numbers should not be adjacent to each other and two odd numbers should not be adjacent to each other
Numbers should be ordered in incremental order.
Print all possible combinations
While the logic above is just a random one. Debug method can be reused for any program.
