Align Whitespace

Align C/C++ declaration, assignment, parameter, call, and macro blocks around the active cursor line.

Examples:

int a;
float b;

becomes:

int   a;
float b;

MyStruct foobar = {1, 2, 3};
YourStruct bax = {};
HisStruct baz = {5};

becomes:

MyStruct   foobar = {1, 2, 3};
YourStruct bax    = {};
HisStruct  baz    = {5};

int lerp(
    int a,
    int b,
    float r,
);

becomes:

int lerp(
    int   a,
    int   b,
    float r,
);

int x = lerp(1, 2, 0.5f);
float xx = lerp(11, 22, 1);

becomes:

int   x  = lerp(1,  2,  0.5f);
float xx = lerp(11, 22, 1   );

#define FOO(X) \
    X(a, 1, 2) \
    X(aa, 11, 22) \
    X(aaa, 111, 222)

becomes:

#define FOO(X)      \
    X(a,   1,   2)  \
    X(aa,  11,  22) \
    X(aaa, 111, 222)

Command

• Align Whitespace: C/C++ Block

Default keybinding

• F1 for *.cpp, *.cc, *.cxx, *.h, *.hpp

Notes

• The alignment logic is implemented in python/align_cpp_block.py.
• The extension shim in extension.js only registers the VS Code command and invokes Python.
• The default Python command is python3. You can change it with the alignWhitespace.pythonCommand setting.
