Script to insert grep style in all Paragraph styles

Yes, it is. Here's an example:

Main();

function Main() {
var doc = app.activeDocument,
parStyles = doc.allParagraphStyles,
charStyle = doc.characterStyles.item(“Figure numbers”),
parStyle, i, grepStyle;

if (!charStyle.isValid) doc.characterStyles.add({name:”Figure numbers”, fontStyle:”Bold”});

for (i = 1; i < parStyles.length; i++) {
parStyle = parStyles[i];
grepStyle = parStyle.nestedGrepStyles.add();
grepStyle.grepExpression = “d+”;
grepStyle.appliedCharacterStyle = charStyle;
}
}

The script adds a grep style to every paragraph style including styles in groups.

I forgot that the forum removes backslashes — add two backslashes before d+.

grepStyle.grepExpression = “\d+”;

Kasyan – thanks! I'll definitely try this one.

What I posted is just an example of how to do this. I suppose that you want to write the script yourself and will modify the character style and the grep-expression according to your needs.

If you want someone to write a script for you, you have to be more specific: tell us what InDesign version you are on, what character style and grep-expression you want to apply, etc.

Yes, it's easy to make a script to change the font color of text in all the styles. What is the swatch name? Does it already exist in the document, or the script should create it if it doesn't exist yet?

Query 2:

Main();

function Main() {
var doc = app.activeDocument,
parStyles = doc.paragraphStyles,
swatch_1 = doc.swatches.item(“C=60 M=40 Y=0 K=0”),
swatch_2 = doc.swatches.item(“C=15 M=100 Y=100 K=0”),
i, parStyle;

if (swatch_1.isValid && swatch_2.isValid) {
for (i = 0; i < parStyles.length; i++) {
parStyle = parStyles[i];
if (parStyle.fillColor == swatch_1) parStyle.fillColor = swatch_2;
}
}
else {
alert(“A swatch doesn't exist.”);
}
}

Query 1:

I still don't understand what you want to achieve. Scripting grep style is quite straightforward — as in the user interface, you have to set only two parameters: appliedCharacterStyle (the character style applied to the text) and grepExpression (the GREP expression used to apply automatic styling).

Probably, for the first parameter, you might want to use ^\d+ to apply the character style to any number of digits at the beginning of a line. I don't get what you mean by (Figure No : *) — a number followed by colon and some text?

First you have to create and test a grep-expression in InDesign to make sure that it works as expected. Then you can copy and paste it to the script and escape backslashes (double them in script).

Second parameter — character style:

grepStyle.appliedCharacterStyle = doc.characterStyles.item(“Type in your character style here”);

I used the following line in my example just to be on a safe side: if the character style doesn't exist in the document, create it, name it as “Figure numbers” and apply Bold to it. You can remove it if you're sure that the style is always present in the document, otherwise the script would throw an error.

if (!charStyle.isValid) doc.characterStyles.add({name:”Figure numbers”, fontStyle:”Bold”});

Don't use Notepad to save scripts — use ExtendScript Toolkit instead.

Use this grep-expression in the script then:

grepStyle.grepExpression = “Figuresd+.d+”;

which means word 'Figure' followed by a space, one ore more digit, a period and one ore more digit.

I forgot that the forum removes backslashes again.

Here's another attempt:

grepStyle.grepExpression = “Figure\s\d+\.\d+”;

The forum software spoils the code: before the closing parentheses it replaced inch marks with quotes. If you change them back to parentheses, it should work. Here I posted the script to avoid problems with coping and pasting to/from the forum.
