Conditional compare using C #define

[mschmelz]

I write embedded C Source for a handful of variants of a device.
The code parts that vary for each variant are activated using #define,
eg.
#define DEVICE_VARIANT1
...
#ifdef DEVICE_VARIANT1
... do something
#endif

Beyond Compare does an awesome tagging of differences in C-Source.
Is there a way maybe to only list differences within valid #defines ?
(e.g. marking all else as non-source differences)

Hello,

Not directly, no. The File Format is for a specific format, which defines entire grammars. We don't have a method to limit to specific sections of an entire file.

If you select a section, select to Copy it, and then select a second section, and right-click Compare to Clipboard, this can compare just two sections of text in a new tab.
