Inline
CLion provides the following inline refactorings:
- Inline Constant. This refactoring is opposite to the Extract Constant refactoring.
- Inline Define. This refactoring is opposite to the Extract Define refactoring.
- Inline Typedef. This refactoring is opposite to the Extract Typedef refactoring.
- Inline Parameter. This refactoring is opposite to the Extract Parameter refactoring.
- Inline Function. This refactoring is opposite to the Extract function refactoring.
Inline Function Refactoring Examples
| Before | After |
|---|
| //This function will be inlined
int fdiff(int x, int y, int factor);
int main(){
int x = 10;
int y = 9;
int z = fdiff(x, y, 2);
return 0;
}
int fdiff(int x, int y, int factor) {
return (x-y) * factor;
}
| int main(){
int x = 10;
int y = 9;
int z = (x - y) * 2;
return 0;
}
|
| Before | After |
|---|
| int main (int argc, const char * argv[]) {
@autoreleasepool {
float result;
//The third parameter will be inlined
result = mulfunc(10, 20, 2);
}
return 0;
}
float mulfunc(int x, int y, int factor) {
return x * y * factor;
}
| int main (int argc, const char * argv[]) {
@autoreleasepool {
float result;
result = mulfunc(10, 20);
}
return 0;
}
float mulfunc(int x, int y) {
return x * y * 2;
}

Perform inline refactoring
- Place the caret in the editor at the desired symbol to be inlined.
- Do one of the following:
- On the main menu or on the context menu, choose .
- Press Ctrl+Alt+N.
- In the Inline dialog box that corresponds to the selected symbol, confirm the inline refactoring or view the selected symbol usages in Find Refactoring Preview.
