Dear Stack Exchange Community,

I see other solutions for this but I'm struggling with the regex I need to adapt them to my situation.

I have software-generated files that have lib object member properties with names that I need to replace. I need to use sed to find whatever name of the property, and replace it with the base file name.

Starting with a .js file named bobby.js that contains:

// stage content:

(lib.Scenario2IntroFigure0 = function(mode,startPosition,loop) {

    stuff

}

Ending with the same bobby.js file but it now has:

// stage content:

(lib.bobby = function(mode,startPosition,loop) {

    stuff

}

NOTE: Scenario2IntroFigure0 is different for every file, unfortunately.

Pseudocode describing what I think I should do:

A. Isolate the old name by looking for whatever is between this pattern::

// stage content:

(lib.

B. And this ending pattern:

= function(mode,startPosition,loop) {

C. Get the file base name itself with:

FILENAME=$(basename $1 '.js')

D. Replace old name with file base name and overwrite the file like:

sed -i "s/Scenario2IntroFigure0/$DA_FILE/g" $1

BUT where "Scenario2IntroFigure0" is whatever sed found between those two patterns.

Replace $file with your $1:

file="bobby.js"

filename=$(basename "$file" '.js')

sed -i 's/((lib.).*( = function(mode,startPosition,loop) {)/1'"$filename"'2/' "$file"
