GREP question

[JonathanArias]

Hey guys,

question. i have a really big layout that has lots of "P" values. see screenshots below. How do i tell indesign to apply italics to all of the "P" it find before a "<" or ">" or "="?

Thanks

Jonathan

Well, you could start with this, and see how it works for you. Tested as a paragraph style option.

\bP(?=[<>=])

[DBLjan]

P(<|>|=)(\d+\.\d+|\d+)

This one only finds

P=1.234

P<1.234
P>1.234

P=1

P<1

P>1

[JonathanArias]

this apply italic to the entire thing. i just want to apply italic to the "P"

[JonathanArias]

did not worked

It does for me. Are you sure there is nothing unexpected between that P and the next character? And that you actually have applied this style to that paragraph?

[JonathanArias]

i don't know what i am doing wrong.

[Jongware]

Create a new text frame. Fill it with placeholder text. Type "P<0.01" somewhere inside. Then add this GREP style using the Paragraph panel menu to its containing paragraph only. That should work, right?

There could be an invisibly-thin or other code character in your original text. Typing it a-fresh will make sure the GREP Style works as intended.

Thank You, Jongware!

@Jonathan:

and if your test will pass it possibly indeed means the 'unexpected characters' in your text.

Then you can try to catch and eliminate them using this grep:

Find:

\bP.([<>=])

Change to:

P$1

Or just include that character in the initial code...

[JonathanArias]

did a an empty text frame, applied the style. nothing. see below.

[winterm · Accepted solution]

Ah, for initial code to work your P must be uppercase - true, not with All Caps applied...

That's must be the case.

So, try to add case-insensitive ON/OFF:

(?i)\bP(?=[<>=])(?-i)

[JonathanArias]

still does not work:

[JonathanArias]

this one worked!!

would it help to share the file? i might be making a mistake with setting up the styles? if it works for you guys than it must be something i am doing wrong in the styles.
