GREP Search “Selection” or “Story” ExtendScript ?

[neal derekl34934377]

When looking for Searching via “Selection” or “Story” through GREP using a script — it expands into this convoluted rabbit hole, when you would imagine it would be much simpler .

The short and sweet script, below, works but affects the entire document. I attempted placing “selection” in various places, and tried creating variables to point to various iterations of app.pageItem.selection , app.selection , etc . To no avail.

I commented out the last line I attempted.

As always any help is very much appreciated.

Thank you.

//reset GREP preferences
app.findGrepPreferences=app.changeGrepPreferences=null;
//app.findChangeGrepOptions = app.pageItem.selection
app.findGrepPreferences.findWhat="\r";
app.changeGrepPreferences.changeTo=",\s";
app.activeDocument.changeGrep();
app.findGrepPreferences=app.changeGrepPreferences=null;

Looking for the javascript syntax that affects Find/Change > GREP > Search > Stories (and/or selection)

Just try to use app.selection[0].changeGrep();

"\r" instead  "\\r" "\s" instead "\\s"

… About catching an "active story", e.g. placing the cursor inside it, "app.selection[0].parentStory"

But inverse. In JavaScript, use two
to escape.

\r will find nothing with javascript.

And, using app.activeDocument he's pointing the changeGrep to perform the

changes in entire document.

Absolutely right, Michel. But it will only work for a very select subset of meta-characters that actually mean the same thing in GREP as in JavaScript strings!

Always remember that the JavaScript string translation comes first. What's left after that will be fed into GREP. (A third layer, added by Adobe, translates InDesign's special character codes and functions, all starting with a tilde ~.)

It works because '\r' translates inside the string itself into a literal paragraph return and '\t' to a tab – and you actually can "insert" these characters literally into the GREP dialog as well. (It takes a script...)

BUT! Not all backslash escaped meta-characters behave like that. The codes \d, \s, \w and a long list of others do not translate into a single character or code, and so the backslash is stripped and just the plain letter gets inserted. \b is another one: it inserts a backspace code ("0x08") but within InDesign, that code searches for a Shift-Tab, so it will still do something entirely else than expected.

Bottom line: unless you know from heart all "regular" escaped codes (and what they search for) and all special ones (meta-codes), do yourself a favour and always use double backslashes.

(One of the more addicting features of Python: raw strings. In there no character is parsed, and so it's perfect for constructing regexes out of ordinary strings.)

I definitely stop to try to help. I already stopped in Facebook groups.

Now, I'll stop here too. I must be very stupid. It'll be better for me just

watch, read and learn.

You guys are definitely clever than me. Almost all polite and didactics,

other........

Not at all, Luis Felipe. Just more experienced. Don't give up!

Hi Theunis,

I obviously systematically use the "double backslahes".

I was simply expressing reservations about a peremptory statement!

See you soon and thanks for the explanations [always appreciated!]!

Best,

Michel

You know what at one point I did try just that — instead I just realized I used parenthesis instead of brackets *face palm* .

app.selection(0).changeGrep();  <--- WRONG

Egg on my face — still super noobish with all this.

Thanks — really appreciate it.

Final code below, with a loop that I took from another code I had — which I should have tried to begin with.

//reset GREP preferences
app.findGrepPreferences=app.changeGrepPreferences=null;
app.findGrepPreferences.findWhat="\r";
app.changeGrepPreferences.changeTo=",";
var sel = app.selection; 
    for(var n=0;n<sel.length;n++) 
    { 
        sel.changeGrep(); 
    }; 
//reset GREP preferences
app.findGrepPreferences=app.changeGrepPreferences=null;

What do you mean by: "app.selection"?
