Hi,
In r.univar_main.c, there are a number of string assignments similar to this:
param.percentile->description =
_(“Percentile to calculate (requires extended statistics flag)”);
I am not familiar with the ‘_’ syntax as it is being used here before the opening ‘(’.
The Eclipse editor complains about syntax.
Anyone know what is happening here?
Regards,
Rob Parsons

These are the gettext macros used for the indication of strings (user
messages) to be translated.

I suppose that the Eclipse editor needs to be configured properly for
that (no idea how since I am not familiar with it). Perhaps others
know here?
In any case, the macro need to remain.

Is this relevant to python (scripts) as well?

Yes, e.g.
[neteler@oboe r.unpack]$ grep message *
r.unpack.py: grass.message(_('Raster map <{name}>
unpacked'.format(name=map_name)))

Some examples on _() and n_() use are in locale/README file.

Telling Eclipse that the C dialect is c99 (-std=c99) solved the problem. The macro is now recognized.

Excellent. Please consider to update the page

in order to help others with the hint(s) which easily get lost in the
email archive.

Ok.
I am getting smarter.
Forget what I said about using the -std=c99 option to get Eclipse to recognize the _() macro. The syntax error being reported by the Eclipse editor (CDT parser) is caused be the definition of PACKAGE on the gcc command line.
-DPACKAGE="“grassmods”"
Eclipse invokes the GRASS ‘make default’ tool and builds the system or module with no problem. The Eclipse parser/indexer builds its database of symbols and cross-references by scanning all the C/C++ source code, Python scripts and make output.
It learns that the value of PACKAGE is the string:
"“grassmods”"
This value is OK when building the system or module because the build is performed within a MSYS shell.
The Eclipse editor and CDT parser likes this value:
“grassmods”
I am not suggesting any kind of change. The _() macro works. I can successfully compile and from within Eclipse. The ‘syntax error’ is more of a nuisance than anything else. Maybe I can figure out how to tell Eclipse to ignore this syntax.
Eclipse 4.5 Mars for GRASS development on Windows 7 is working very well. I can browse, build, run, debug GRASS C/C+ modules and Python scripts.
I will document this on the wiki.
