Eclipse CDT formatter lines up columns with macros incorrectly?-CodePudding

Background

Using STM32CubeMxIDE 1.8 (Eclipse® 2021-03 and CDTTM version 10.2.0). I've adjusted to a custom formatter with Window >> Preferences >> C/C >> CodeStyle >> Formatter >> Edit, and created my own with some Google, GNU, and personal preference. I want something like this for large functions:

foo(0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000,
    0x00000000, 0x00000000, 0x00000000, 0x00000000);

Issue

Given my poorly formatted code:

#define mainEXAMPLE_32BIT  0x00000000

__myExampleFunctionFoo (  mainEXAMPLE_32BIT, mainEXAMPLE_32BIT,mainEXAMPLE_32BIT,    mainEXAMPLE_32BIT,mainEXAMPLE_32BIT);

If I format by save or pressing CTRL SHIFT F and format the entire page it becomes:

__myExampleFunctionFoo(mainEXAMPLE_32BIT, mainEXAMPLE_32BIT,
                       mainEXAMPLE_32BIT, mainEXAMPLE_32BIT,
                       mainEXAMPLE_32BIT);

Great! This is what I want.

But it only works once. When I save file or press CTRL SHIFT F a second time and I now have:

__myExampleFunctionFoo(mainEXAMPLE_32BIT, mainEXAMPLE_32BIT,
mainEXAMPLE_32BIT,
                       mainEXAMPLE_32BIT,
                       mainEXAMPLE_32BIT);

The second argument moves forward to the same indentation as it's function. This only seems to happen with defines/macros.

I've tried my own, GNU, and other CDT formatters options. I suspect if it's not a bug that it's an issue with expansion of macros or generally some macro option.

Any advice? I suspect the best response I'll get is to install Clang-Format.

CodePudding user response：

I could find nothing on this, no way to see what the built in formatter was doing and why, and did eventually switch to clang-format.

The plug-in for Eclipse is called CppStyle.
