By toggling the g:ycm_seed_identifiers_with_syntax option, the user can now tell
YCM to seed the identifier database with the language's keywords.
This is off by default because it can be noisy. Since the identifier completer
collects identifiers from buffers as the user visits them, the keywords that the
user cares about will already be in the database, regardless of the state of the
new option. So the only keywords added will be the ones the user is not using.
Meh. But people want it so there.
Fixes#142.
Everything that needs access to filetype_map_ has been split into a new class
called IdentifierDatabase. This class is thread-safe. Previously, multiple
threads could access filetype_map_ at the same time, some reading things from
it, others writing to it. WTF was I doing? My best guess is that I introduced
this vile stupidity when I added the second thread to IdentifierCompleter;
previously it was impossible for multiple threads to stomp on filetype_map_
because only one thread ever accessed it. I changed that some time ago and
forgot to protect filetype_map_.
Idiot.
Depending on the user, the PrepareClangFlags rewrite of a few commits ago could
break users with an extra "clang: 'linker' input not used" (or similar) error
message because the compiler executable string was not removed from flags
upstream if the user prepended some flags to the output of PrepareClangFlags
before returning it to the caller of FlagsForFile.
Since the rewrite was supposed to be backwards compatible, this needs
to be handled.
It was possible to get a traceback if results[ 'flags' ] was a StringVec; the
code would try to perform results[ 'flags' ] += self.special_clang_flags and
this would then fail because the clang flags would be a Python list.
ycm_extra_conf.py files used to import clang_helpers and then use the
PrepareClangFlags function; this is now unnecessary since the logic from that
function has been moved to flags.py. The old PrepareClangFlags function is still
there (it just returns the flags it gets) for the sake of backwards
compatibility with old ycm_extra_conf.py files.
Knowing those two things (that you need to run latest Eclipse Juno) and you need to create a new project from vim would have saved me a lot of time when trying to make it all work.
I think it's worth adding this information to the README.
