Using Script to Automate Insertion of Thin Space for Company Name in InDesign

Hi @Océane23259082birw, you could do this as a straight find grep, without a script:

If you need a script, this does pretty much the same thing—using find/change grep. It will target the selected text/textframe(s) or, if nothing selected, the whole document.

function main() {

    var doc = app.activeDocument,
        targets = doc.selection;

    app.findGrepPreferences = NothingEnum.NOTHING;
    app.changeGrepPreferences = NothingEnum.NOTHING;

    app.findGrepPreferences.properties = {
        findWhat: '(?<=\\bN)\\s(?=Name\\b)',
    };

    app.changeGrepPreferences.properties = {
        changeTo: '~%',
        noBreak: true,
    };

    if (0 === targets.length)
        targets = [doc];

    for (var i = targets.length - 1; i >= 0; i--)
        if (undefined != targets[i].changeGrep)
            targets[i].changeGrep();

};
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Apply N Name Spacing');

Edit 2024-10-08: added check to see if selected item was greppable.

You don't need a script or thin space.
Create a character style that only uses the ‘No Break’ attribute.
In the paragraph style used for your text, add a GREP style that applies the ‘No Break’ style to the words ‘N Name’.
You'll never forget these words again.

Depending the actual name of the company, you could “fake” a thin space using a GREP style.
