mass renaming of java variables

Question

I have a class with about 50 fields. They are named roughly like this:

config__write_better_code

I want them to look like this instead and not have to rename them all manually:

Config$WriteBetterCode

I'm using eclipse, but anything that can rename the code is welcome.

"$" is reserved: "The $ character should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems." — Hot Licks, Feb 12 '13 at 21:21
Use the Refactor->Rename feature in eclipse for each variable. — DwB, Feb 12 '13 at 21:23
Just use alt+shift+r 50 times. Shouldn't take too long. (that is the shortcut to rename variables in Eclipse, it will also modify wherever it is used). — Simon Verhoeven, Feb 12 '13 at 21:24
I was thinking of using regexes, but they can't save the character and make it uppercase. I need some character that doesn't get used normally in variableNames and so I just took the dollar sign, my pc won't explode now will it? — Diemex, Feb 12 '13 at 21:39

click on the variable name.

1:press [alt] + [shift] + [R]

2:enter the new name.

3:press [enter] to confirm.

-->all instances of this variable will be renamed.

Thx, but I know how to refactor. I was thinking more of a regex based way, because all variables are named by the same pattern. – Diemex Feb 12 '13 at 21:45

The AnyEdit Eclipse plugin might help you (in combination with the rename feature of eclipse):

Convert Camel <-> Underscores

Auto-convert variable names from/to "camel" notation, like thisIsMyFieldName <-> this_is_my_field_name

Just checked, and 1) It only renames one line, not all variable usages 2) It only renames 1 variable, and only if selected – Andrey Oct 20 '16 at 08:37
