fixes warnings with Xcode 14.3 as in previous commit
+ allocate +1 in Log_output buffer - snprintf(MULL, 0...) returns number
of bytes without terminating '\0'. std::string storage isn't guaranteed
to be NULL-terminated (std::string("").at(0) throws an exception). The
buffer is somewhere preallocated 256 which prevents problem but it's
better not to rely upon it.
+ comment out some unused function in LDGM that also triggered the
warning but looked a bit suspicious so it was not clear how to fix
- moved macros to utils/macros.h (not config_common.h that is not going
to be included) and include in config_common.h the macros.h file
instead (later it should be removed)
- avoid dependency of color_out.o on host.o if build outside UG (easiest
for now)
- compile tools with '-g' (obviously for better debuggability)
In Windows, if output is not MSYS, check if output is a terminal and do
not relay on setWinTermAnsiColors() returning true.
+ check for MSYS terminal first (avoids attempt to set ansi color on
MSYS terminal)
refers to #256
Previously colored output using the inline TERM_* macros from color_out.h was
done only using the color_printf() function. Since there are now places
where they are used with log_msg(), we need to prune ansi codes here
too.
Use inline ANSI escape sequences instead of modifiers.
This allows more convenient formatting without the need to use multiple
calls (possibly interleaving).
ANSI escape sequences are nowadays supported also in Windows terminals
(PS, cmd).
