Below is a simple script for a grid of random symbols. It's a slow running script, so I've limited the number of symbols to 1000. Remove the limit by deleting line 2. Randomly distributed spacing may be achieved with a more complex script. (200 * 200 mm artboard.) var limit;
limit = Math.sqrt(1000);
var size = 12; // font (cell) size
var doc = app.activeDocument;
var num_x = doc.width / size;
var num_y = doc.height / size;
if (limit && num_x > limit) num_x = limit;
if (limit && num_y > limit) num_y = limit;
var x = size;
for (var i = 0; i < num_x - 1; i++) {
var y = - size;
for (var j = 0; j < num_y - 1; j++) {
var min = 32;
var max = 127;
var n = Math.floor(Math.random() * (max - min + 1)) + min;
var text = doc.textFrames.pointText( [x, y] );
text.contents = String.fromCharCode(n);
text.textRange.textFont = textFonts["TimesNewRomanPSMT"];
text.textRange.size = size;
text.textRange.justification = Justification.CENTER;
text.rotate(-90);
y = y - size;
}
x = x + size;
}

My thinking was similar to @m1b , except I wasted my time doing the math long hand. As far as I can tell, the math is correct, any desired result depending on the tolerance (line 1). var tolerance = 1; // points
var doc = app.activeDocument;
var pathItems = doc.selection;
for (var i = 0; i < pathItems.length; i++) {
main(pathItems[i])
}
function main(pathItem) {
var points = pathItem.pathPoints;
var P0 = points[0].anchor;
var P1 = points[0].rightDirection;
var P2 = points[1].leftDirection;
var P3 = points[1].anchor;
// handles, i.e. distances between (1) P0 and P1 and (2) P2 and P3
var handle1 = Math.sqrt(
(P0[0] - P1[0]) * (P0[0] - P1[0]) + (P0[1] - P1[1]) * (P0[1] - P1[1])
);
var handle2 = Math.sqrt(
(P2[0] - P3[0]) * (P2[0] - P3[0]) + (P2[1] - P3[1]) * (P2[1] - P3[1])
);
// theta / 2 is angle between handle and line between anchors
var opposite1 = P1[1] - P0[1];
var adjacent1 = P1[0] - P0[0];
var angle1 = Math.atan2(opposite1, adjacent1);
var opposite2 = P3[1] - P0[1];
var adjacent2 = P3[0] - P0[0];
var angle2 = Math.atan2(opposite2, adjacent2);
var theta = (angle1 - angle2) * 2;
if (opposite2 < 0) {
theta = theta * -1;
}
// radii, if arc were circular
var alpha = 4 / 3 * Math.tan(theta / 4);
var R = handle1 / alpha;
// midpoint of curve
var M = [
(P0[0] + 3 * P1[0] + 3 * P2[0] + P3[0]) / 8,
(P0[1] + 3 * P1[1] + 3 * P2[1] + P3[1]) / 8
];
// midpoint of line between anchors
var Q = [(P0[0] + P3[0]) / 2, (P0[1] + P3[1]) / 2];
// centre of circle

var dy2 = adjacent * Math.cos(angle2);
var O = [Q[0] + dx2, Q[1] - dy2];
// distances between M and O

(M[0] - O[0]) * (M[0] - O[0]) + (M[1] - O[1]) * (M[1] - O[1])

The approximation in the link is only for a "unit right" circular arc, that is to say, an arc with a radius of 1 and an angle of 90°, or a quarter circle. I presume you are dealing with arcs of unknown angles and radii, which is not as straightforward.

I can't replicate the problem, possibly because I don't have Arabic enabled. Assuming it's a bug, you could just re-size. var size = layers[0].textFrames[0].textRange.size;
layers[0].textFrames[0].contents = "عنب كرز";
layers[0].textFrames[0].textRange.size = size;

Copy and paste the code to a .jsx file. (You can create a .txt file and change the extension to .jsx.) Then, while your document is open in Illustrator, go to File > Scripts > Other Script (Ctrl+F12). Find the file you just created and open it; this will run the code.

This should output a list of words at line breaks (but not paragraph breaks). A text frame should be selected. var output = "";
var paragraphs = app.selection[0].paragraphs;
for (var i = 0; i < paragraphs.length; i++) {
var lines = paragraphs[i].lines;
for (var j = 0; j < lines.length - 1; j++) {
var index = lines[j].words.length - 1;
output += lines[j].words[index].contents + "\n";
}
}
alert(output);

The script was not written with invisible and locked layers in mind. Can you share a test AI file (through a file sharing site)?

I presume you want each layer saved as different PDFs and not all layers saved as the same PDFs but with different names. The script may be slow running, so test before running on a heavy document. function main() {
var folder1 = Folder.selectDialog();
var doc1 = app.activeDocument;
for (var i = 0; i < doc1.layers.length; i++) {
app.selection = null;
var layer1 = doc1.layers[i];
layer1.hasSelectedArtwork = true;
var selection = doc1.selection;
var doc2 = app.documents.add();
for (var j = 0; j < selection.length; j++) {
selection[j].duplicate(doc2, ElementPlacement.PLACEATEND);
}
var PDF1 = new PDFSaveOptions();
var name1 = layer1.name;
var file1 = new File(folder1 + "/" + name1);
doc2.saveAs(file1, PDF1);
doc2.close(SaveOptions.DONOTSAVECHANGES);
}
}
main();

Regarding the first point, this is what your original script gives me. If this is what you want, and you are not getting, I would focus on debugging this. One possibility is that the script doesn't handle items >1 group deep. Could you show the hierarchy of the items in an expanded layers panel?

I'm a fan of Deke McClelland. He wrote one of the first, if not the first, book on Illustrator in 1988. He has three courses: fundamentals, advanced and mastery. If you like and finish the first, you can move onto the other two. https://www.linkedin.com/learning/illustrator-one-on-one-fundamentals https://www.linkedin.com/learning/illustrator-one-on-one-advanced https://www.linkedin.com/learning/illustrator-one-on-one-mastery

The selected Pantone/Focoltone are SpotColors that have different properties to the colors your script is accessing. The properties you are accessing are (an RGB example): swatch.color.red swatch.color.green swatch.color.blue swatch.color.typename (RGBColor) For SpotColors, you want: swatch.color.spot.color.red swatch.color.spot.color.green swatch.color.spot.color.blue swatch.color.spot.color.typename (RGBColor) swatch.color.typename (SpotColor) Add a conditional to check if a color.typename is SpotColor and, if it is, go down the above route. BTW, there's no JSON.stringify in Extendscript. How are you reading the output?

The question is unclear to me. Are you asking how to distinguish between variables from the included file and variables from the main file? If so, the answer is: not possible. Both sets of variables are added as properties to the same global object.

The error implies that the script is either not saved in the right format or not being run in the right way. The script should be saved with a .jsx extension. Copy the script to a plain text file and save with a .jsx extension. I do not use a Mac, but I understand that Apple's TextEdit, by default, will save as rich text; this is not what you want; you want plain text. The script should be run from illustrator, by going through File > Scripts.

Variables used in a function should be declared either before the function call or within the function. To compare colors, the components of the colors should be compared. replaceWord(/511/gim, "410");
function replaceWord(strFind, strReplace) {
var doc = app.activeDocument;
var col = new RGBColor();
col.red = 255;
col.green = 0;
col.blue = 0;
var frame, words, word;
for (var i = 0; i < doc.textFrames.length; i++) {
frame = doc.textFrames[i].textRange;
words = frame.words;
for (var j = 0; j < words.length; j++) {
word = words[j];
if (word.fillColor.red != col.red ||
word.fillColor.green != col.green ||
word.fillColor.blue != col.blue) {
new_string = word.contents.replace(strFind, strReplace)
if (new_string != word.contents) {
word.contents = new_string;
word.fillColor = col;
}
}
}

It's a bug. A gradient's origin, length and angle cannot be overwritten. Here's an elaborate workaround courtesy of CarlosCanto. This doubles a gradient's length (of a selected item) in the right direction: var fillcolor = app.selection[0].fillColor;
app.selection[0].filled = false;
app.selection[0].fillColor = fillcolor;
app.selection[0].fillOverprint = app.selection[0].fillOverprint;
var f = app.getScaleMatrix(200, 100); // double x
app.selection[0].transform(
f, false, false, true, false, 0, Transformation.LEFT);

I presume it's a bug. It appears that re-assigning a pathItem's height throws an "unknown scripting error" once it's a 0. This can replicated by the following: var rect = app.activeDocument.pathItems.rectangle(0, 0, 60, 60);
app.redraw();
alert("rect.height = " + rect.height);
rect.height = 0
app.redraw();
alert("rect.height = " + rect.height);

rect.height = 60;
