I rely on uncrustify to format C source files and I would like to update from v0.69 to v0.74 but .. I can't get this config consistent:
Let's consider the following example (which is already formatted the way I want it to be):
#if defined(CONFIG_HAS_A)
#define DEVICE_NAME__A_LIST \
A1_NAME \
A2_NAME \
""
#define DEVICE_NAME__A_COUNT \
A1_COUNT + \
A2_COUNT + \
0
#endif
#if defined(CONFIG_HAS_B)
#define DEVICE_NAME__B_LIST \
B1_NAME \
B2_NAME \
B3_NAME \
""
#define DEVICE_NAME__B_COUNT \
B1_COUNT + \
B2_COUNT + \
B3_COUNT + \
0
#endif
Using the version 0.74 of uncrustify, the above example code gets formatted to this:
#if defined(CONFIG_HAS_A)
#define DEVICE_NAME__A_LIST \
A1_NAME \
A2_NAME \
""
#define DEVICE_NAME__A_COUNT \
A1_COUNT + \
A2_COUNT + \
0
#endif
#if defined(CONFIG_HAS_B)
#define DEVICE_NAME__B_LIST \
B1_NAME \
B2_NAME \
B3_NAME \
""
#define DEVICE_NAME__B_COUNT \
B1_COUNT + \
B2_COUNT + \
B3_COUNT + \
0
#endif
As you can see, the resulting format for the first define (DEVICE_NAME__A_LIST) looks weird and inconsistent compared to the rest of the file ..
What is the right uncrustify config option to avoid this?
NOTE: I found the pp_ignore_define_body option, but it is way too sever as I simply would like the code to be indented one level.
EDIT: I found out that some *_NAME empty macros cause uncrustify to misbehave right after them.
Regarding the few number of files concerned with this issue I wrapped the concerned macros with *INDENT-OFF* and *INDENT-ON*:
/* *INDENT-OFF* */
#define DEVICE_NAME__A_LIST \
A1_NAME \
A2_NAME \
""
/* *INDENT-ON* */
These tags prevent uncrustify from processing the encapsulated content.
