i want to make the filename+spaces=211 characters
but the problem is that if the file name characters = 30
i would need 181 spaces
while if file name characters = 80
i would need 131 spaces
i have tried advanced renamer
tags options + spaces .
<Name>
..
and even this script in the scripts section
var maxLength = 25;
var name = item.name;
var date = app.parseTags("<Year Modified><Month Modified><Day Modified>");
var numSpaces = maxLength - name.length - date.length;
var spaces = "";
for (i = 0; i < numSpaces; i++) spaces += " ";
return name + spaces + date;
but it give me this error
name is not defined in the line 3
the script that works using advanced Renamer
var maxLength = 222;
var name = item.name;
var date = app.parseTags("<Year Modified><Month Modified><Day Modified>");
var numSpaces = maxLength - name.length - date.length;
var spaces = "";
for (i = 0; i < numSpaces; i++) spaces += " ";
return name + spaces + date;

You could use String#padEnd(), to add whitespaces to the end of your filename strings so that the resulting string has a minimum length a specified by you.
Consider the snippet below until where fileNameA.padEnd(211) returns a new string with the same leading characters as fileNameA, but with whitespaces padding the remainder of the string such that the string has length 211:
const fileNameA = 'your file name';
const fileNameB = 'some other big file name';
const paddedFileNameA = fileNameA.padEnd(211);
const paddedFileNameB = fileNameB.padEnd(211);
console.log(`
paddedFileNameA:
"${paddedFileNameA}"
length of paddedFileNameA: ${paddedFileNameA.length}
`)
console.log(`
paddedFileNameB:
"${paddedFileNameB}"
length of paddedFileNameB: ${paddedFileNameB.length}
`)
Update
I'm not familiar with the scripting feature set in Advanced Renamer, however you might find this works for you:
/*
Set length to 211
*/
var maxLength = 211;
var name = item ? item.name : '';
var date = app.parseTags("<Year Modified><Month Modified><Day Modified>");
/*
Ensure variables are not undefined or null
*/
if(!name) {
name = '';
}
if(!date) {
date = '';
}
/*
Construct result string
*/
var result = name;
for (i = 0; i < (maxLength - (name.length + date.length)); i++) {
result += ' ';
}
result += date;
return result;
Problem: I'm using qzTray to print a receipt, earlier i was using html format but the print quality was not good. so i shifted to JavaScript and wrote bunch of functions to print the receipt, i am using this function to print 42 character on each line, i have a string of 105 characters, the string will be printed in 3 lines. I've written some code but its not working entirely, can anyone give me a hint how to do this ?
first line is printed fine but from second line and onward the substr looks like its not working, i don't know why.
Thanks is advance.
window.const_alignLeft = '\x1B\x61\x30';
window.const_newLine = '\x0A';
function getItemRowFull(itemTitle, itemPrice = null) {
var totalColsPerPage = 42;
var leftCols = 35;
var marginSpace = totalColsPerPage === 48 ? '' : ' ';
if(itemTitle.length > leftCols) {
leftCols = (!itemPrice) ? totalColsPerPage : leftCols;
let itemTitleLength = itemTitle.length;
let receipt = '';
let startFrom = 0;
let remainingCharacters = itemTitle.length;
while (startFrom < itemTitleLength) {
receipt += const_alignLeft + marginSpace + itemTitle.substr(startFrom, startFrom + leftCols);
receipt += const_newLine;
remainingCharacters = (remainingCharacters + itemTitleLength) - (itemTitleLength + leftCols);
startFrom = (startFrom + leftCols);
}
return receipt;
}
}

In a Google Sheet, I have 3 raw data worksheets within one google spreadsheet ('Category1'),('Category2'),('Category3'). These worksheets are constantly updated by people in my business but unfortunately the data isn't in a normailised form to be able to run efficient queries.
I would like to create a script that automatically generates a normailised Output ('Category1 Output'),('Category2 Output'),('Category3 Output') of this raw information that automatically updates itself when someone makes a change in the raw tabs.
In the google sheet below, I have provided an example of what one Category needs to look like. 'Category1' worksheet is the raw that is constantly updated by everyone. 'Category1Output' is the final output worksheet that automatically updates itself when an edit is made in the 'Category1' worksheet.
Google Sheet Link
The Questioner has three sheets in a defined columnar layout - essentially several rows per data set and several columns (one for each time period). These sheets are not being replaced, but a summarised version was sought where filtering could be used to focus effectively on relevant data. Thus, each sheet to be translated from columnar format to row-wise format.
The process itself is straightforward. The source data comprised 64 products # 8 data rows per product. The output records were #1,350.
The questioner's code was hung up on the conversion of data to the output format. The use of 8 rows of data per product is important, and the code includes a check that the quotient the total number of rows of data divided by eight is an integer. In addition, the names of the Source sheet and the Output sheet are called by name (getSheetByName) so that the code can be easily applied to any named Input Sheet and any named Output sheet. The only proviso is that both sheets must exists beforehand.
Initial resolution of the questioner's code hiccup was successful and using the methodology of getDataRange and getValues before the loop greatly improved performance. There are two loops; one with a vertical orientation, moving through the rows of data; and the second with a horizontal orientation moving through the time-related columns. However performance was initially very inefficient and the code was timing out before completion.
I modified the code to build a single 2D array and save it to the Output sheet just once at the end of the loops. This had a dramatic effect on performance. Total time to complete dropped from several minutes to less than 5 seconds.

UPDATE
The second element of the Questioner's code deals with updating data to an "Output Sheet" as changes are made to "Category" sheets. The questioner's code for the update was OK, but was missing the translation of the source range on the Category Sheet to establishing the target range on the Output sheet.
The solution involves a rubric based on mathematical number sequence. In this case, the mathematical sequence is the row numbers for products on the source sheet; each product occupies 8 rows, and the first row is #10, so the sequence is 10,18,26,34....
onEdit returns the range of the changed cell and getRow and getColumn can be used to establish the co-ordinates of the changed cell. The challenge is, knowing the actual row number that was changed, to establish what number in the sequence of rows (and hence the product name) that the actual row number represents. It is also extremely unlikely (eight to one) that the changed row will coincide with the first row for a product number.
So it is necessary to apply the algorithm for mathematical sequences - twice. The formula to determine the nth number in a sequence of numbers is An = A1 + (D x(n-1)), where A1 is number for the first row (in our case, 10), D= the difference between each number in the sequence (in our case, 8), and n= the number in the sequence (in our case, the changed row number).
The first pass is to establish the position number in the sequence of numbers(product groups) represented by the actual changed row. It is very likely that the outcome is not an integer, i.e. it does not coincide with the first row for a Product group. So, the result is rounded down to the nearest integer, and the algorithm is processed a second time.
However this time we know the position of the sequence number, and we solve to find the value of the number. In this case, the formula is ((An-A1)/D)+1. This will return the row number in the Source sheet corresponding to the first row for the relevant Product group. We use this to identify what type of field was changed (Category, Display, etc).
The column number indicates the week number. Week 1 starts in Column F, so get column enables us to establish whether the change took place in a week column (or whether it was to left of Column F). If to the left, then "not my problem", if in F or higher, then it needs to be noted.
Lastly, we do a getRangeValue for the Target sheet and look for a match of the week number in Column A AND the truncated Product name in column B. This provides the co-ordinates to setValue for the new value tracked from OnEdit.

// Update relevant Outputsheets on changes in Category sheets

I'm trying to get compound assignment working inside a loop in Javascript but it's throwing NaN at me and I don't know why as I'm still fairly new to Javascript. I am essentially trying to translate this into a jQuery-Validation custom method: https://github.com/pfwd/NHSNumber-Validation/blob/master/PHP/NHSValidation.class.php
Here's what I have so far
// Taken from https://github.com/pfwd/NHSNumber-Validation
var multipliers = {1:10, 2:9, 3:8, 4:7, 5:6, 6:5, 7:4, 8:3, 9:2};
var currentSum, currentNumber, currentMultiplier = 0;
//Get submitted NHS Number and remove whitespace
var givenNumber = value.replace(/\s+/g, '');
// Get length
var numberLength = givenNumber.length;
console.debug(givenNumber);
console.debug(numberLength);
// Number must be 10 digits in length
if (numberLength !== 10) {
return false;
}
// Check number
var checkNumber = value.substring(9);
console.debug(checkNumber);
// Loop over each number in the string and calculate the current sum
for (var i = 0; i <= 8; i++) {
var minus = i-1;
var plus = i+1;
currentNumber = value.charAt(i);
currentMultiplier = multipliers[plus];
currentSum += (currentNumber * currentMultiplier);
console.debug("i is " + i + " & current Num: " + currentNumber + " plus current multi: " + currentMultiplier + " plus " + currentSum);
}
var remainder = currentSum % 11;
var total = 11 - remainder;
console.debug(currentSum);
I don't know if the minus and plus vars are necessary but they're something I tried while trying to fix the NaN issue. A typical console debug line looks like this:
i is 0 & current Num: 1 plus current multi: 10 plus NaN
I've also tried this with the same NaN result:
currentSum = currentSum + (currentNumber * currentMultiplier);
var currentSum, currentNumber, currentMultiplier = 0;
is incorrect, and only initalizes currentMultiplier.
It should be
var currentSum, currentNumber, currentMultiplier;
currentSum = currentNumber = currentMultiplier = 0;
