Tip: #945 - Run Vim command on current C/C++/Java function

It is often useful to restrict the range of commands like s or g to the function one is editing currently. For C/C++ and java
- cmap ;tf ?^{??(?,/^}/
maps the keystrokes ;tf (_t_his _f_unction) to the range of the function in which the cursor is currently located. It works by searching backwards for a { occurring in the first column, and then for a ( to find the start of the function. A } in the first column ends the function body.
For example, you want to change the name of a function argument in the current function from i to ii:
int foo(int i,
int j)
{
// ...
i++;
return i;
}
Type <esc>:;tf followed by the subsitution command s/\<i\>/ii/g. The command line now reads:
- ?^{??($,/^}/s/\<i\>/ii/g
Press <cr> to execute and observe the change:
int foo(int ii,
int j)
{
// ...
ii++;
return ii;
}
The range can be used with other commands too.
This tip assumes that:
- your source code is indented, so that curly braces on the first column always open or close a function body
- a function name is followed by a (. This is true in c, mostly true in c++ and java, and true to a limited extend in perl.
This tip does not work for constructor definitions in c++ and java, since they can contain many parentheses:
Foo(int bar, int baz):
mBar(bar),
mBaz(baz)
{}
Comments
I don't know a lot of people that actually put braces on the FIRST column in Java... except for the class.
