Need help with a GREP expression

seems should easy, i've lost hours of life already. suggestions appreciated.

 

the type examples:

 

best bets weekend: this line of type, follows colon , ends in period, question mark or exclamation mark. more 1 sentance. details, page 21

 

 

this example, not precede colon. more 1 sentence, ends in period, question mark or exclamation mark. details, page 21

 

 

i need grep expression will:

 

-- when type begins colon precede (first example), apply "bold" character style type up-to-and-including colon. i'm defining colon precede type leading instance of colon, followed space --- occurs before sentence-ending punctuation (., ?, !).

-- not apply character style if there not colon precede (second example).

-- apply same "bold" character style last sentance in paragraph -- if sentence not end punctuation. bold-face page reference.

-- preferable incorporate functionality 1 paragraph style.

 

thanks help.

working memory (jus' browsing on ipad can't readily test it):

 

1. add grep style this:

 

^[^.?!]+:

 

and have apply bold character style.

 

2. add grep style:

 

(?<=[.!?] )[^!?.]+$

 

and have apply bold well.

 

> preferable incorporate functionality 1 paragraph style.

 

you can have many different grep styles want in each paragraph style. (although computer fan may start whining after fifth or so.)
