What is the opposite of comment (in the jargon of programming)?

In programming, commenting: To disable a section of source code by converting it into a comment. If you do not want to run this line of code, just comment it out!

What is the opposite of comment it out? Is it disable comment or just don't comment it out?

For example:
In my daily routine as a programmer, customers always say they want some features, and then after some time they don't need them any more. So I just comment on that part of the code I add! But after some time they want that feature again, so what if I want to say I disable that comment?

Uncomment is the usual opposite of comment in programming contexts. It is commonly used in computing circles although it hasn't made it into dictionaries (I did not find it in Merriam-Webster, Collins, Macmillan, or OED online).

It is defined in Wiktionary as "1. (programming, transitive) To convert (text that has been commented out) back into source code so that it will no longer be ignored by the compiler or interpreter." ("Uncomment", Wiktionary, as of Nov 22, 2022.)

YourDictionary has a similar entry.

You can also find it used in many programming manuals and other documentation, e.g. from IBM: "You can use the Comment/Uncomment feature of the Rules Editor to comment or uncomment manually entered lines of code or commentary."
