Mastering the IDE: Rename
The IDE simplifies a lot of typical actions. For instance, suppose you want
to rename a declaration. Inventing a good name for a val or a function is
difficult, so it's often an iterative process. You may create and use a
function, but then think up a better name for it.
Find and Replace
may lead to unexpected results, because the name might
appear in different contexts, for instance inside strings or comments. In the
code example you may see the answer as a name of val, which is a part of the
string literal as well. If we're talking about renaming functions, it's even
more complicated, because the function might be used in many files, and doing
rename properly in many places by hand is a complicated task.
IDE allows to rename a declaration automatically.
Put the caret on the val name and press
&shortcut:RenameElement;.
Alternatively, you may choose Refactor
from the application menu, then choose Rename.
Rename the val name to result without renaming "answer" in the string
literal.
