The not found message used to instruct users on how to install the OmniSharp completer was using an underscore while the argument to the install script uses a hyphen. The message now uses the correct naming format.
Vim is not thread-safe so posting a message to Vim from a non-GUI thread causes
a crash *sometimes*. I was aware of this problem before, but didn't catch this
instance of it in code review.
Fixes#479.
We could just remove the "dup: 1" part in the completion dict, but that would
leave the duplicate removal up to Vim which would be slow. Also, we might not
end up returning the correct number of results then.
For instance (`|` represents the cursor):
1. Buffer state: `foo.|bar`
2. A completion candidate of `zoobar` is shown and the user selects it.
3. Buffer state: `foo.zoobar|bar` instead of `foo.zoo|bar` which is what the
user wanted.
This commit resolves that issue.
It could be argued that the user actually wants the final buffer state to be
`foo.zoobar|` (the cursor at the end), but that would be much more difficult
to implement and is probably not worth doing.
Fixes#374.
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.
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.
Fixes#307. Error is thrown when g:ycm_min_num_of_chars_for_completion
option is set to 0 user tries to delete an identifier which starts at
the beginning of the line.
This is for filename completion in the case of C-family include completion. The
path was being assembled incorrectly so os.isdir() was getting the wrong path
and then could not see was it a directory.
A few Completer methods that should have been forwarded to general completers
were not. This broke the identifier completer picking up the current identifier
right after it's typed in.
The issue was that AsyncCandidateRequestReady in the ultisnips completer would
always return false if there were no snippets for the current filetype, leading
to an infinite loop in CompletionsForQuery.
Fixes#270.
This was done by introducing a new ThreadedCompleter class that descends from
Completer. Both JediCompleter and FilenameCompleter descend from
ThreadedCompleter.
This implements the filename completer and introduces integration with
UltiSnips. The user will now see snippets in the completion menu. After
selecting a snippet, the user should invoke the UltiSnips trigger key
(which should be changed from the default of TAB) to trigger the snippet
expansion.
Fixes#77, Fixes#36
Now the user has the option of writing custom logic before ycm_core.so is
loaded. This can be used to dynamically change the location of where ycm_core.so
is loaded by prepending paths to sys.path.
Very, very few people will need this feature, but I'm one of them so there.
This first version only uses the Jedi completion engine after a ".", similar to
how the ClangCompleter works. It is also entirely synchronous and blocks for
quite a while the first time it is called.
- There was a bug in not calling int() on the result of the first call to the
omnifunc.
- We need to be more resilient to badly written omnifuncs and check that the
result of the second call is a list or a dict with a list, as the vim docs say
the omnifunc should return on the second call.
One of the two fixes probably fixes#198 but since I can't repro the error, I
can't be sure.
The base class completer Inner chose the first filetype available and
would use the triggers for it.
The triggers are now chosen considering the first for the current buffer
that is supported by the current completer. If there is no intersection,
it fallsback to considering the first filetype for the buffer.
GetFiletypeCompleter would always return a omnicompleter for the first
filetype in case there was no native completer, and the lookup would
stop.
This changes that behaviour to get all possible completers and tries to
find a native one among them. If no native completer is found, it
returns the omnicompleter for the first filetypes, as it used to.
clang_completer would check if the raw value of '&ft' was one of
supported filetypes for the completer.
Vim allows for multiple filetypes with a '.' separator. A file with
ft=qt.cpp, for example, would not be supported by clang_completer even
though it was a cpp file.
This patch changes that behaviour.
This provides a framework for completer-writers to create
completer-specific commands. I have in mind to use this for the clang
completer to force reloading of a flags module via `:YcmCompleter reload`.
To prevent the execution of malicious code the new default is
to ask the user before a `.ycm_extra_conf.py` file is loaded.
This can be disabled using the option `g:ycm_confirm_extra_conf`.
This commit introduces a helper class `FlagsModules` that keeps track of
and caches the currently loaded modules. To introduce further criteria
for a module look at `FlagsModules.ShouldLoad`.
Also `:YcmDebugInfo` now lists the file that was used to determine
the current set of flags.
`Flags.ModuleForFile` could be used in a user-facing command that
opens the `.ycm_extra_conf.py` corresponding to the current file.
A second command could then force a reloding of this module via
`Flags.ReloadModule`.
Currently, when VIM opens a source file, YCM always defaults to
'g:global_ycm_extra_conf_file' if it exists.
This commit changes YCM's behaviour so that it first tries to find the config
file in the source file's folder (or any of its parents folder), before
falling back to 'g:global_ycm_extra_conf_file'.
Now there's a nice user-configurable setting for when YCM should trigger
semantic completion. This is very useful for the new omni_completer that uses
data coming from Vim's omnicomplete system.
Vim allows setting the filetype string to something like "cpp.c", which means
that the file is both cpp and c (nonsense, but allowed). We need to support such
filetype strings.
We now use the compilation working directory for a file that is specified in the
CompilationDatabase. We don't actually change the working directory of the
process, even temporarily (that would be annoying to users); we munge the flags
coming from the database so that all the relative paths in them are resolved to
absolute ones.
We have to have these beneath the folder where ycm_core.so is placed so that we
get fast completions. If these files are not here, then clang fails to
precompile a file preamble and completions are slow.
This was intended to show the full clang output for a given diagnostic,
including notes. But it appears that libclang does not provide this
functionality...
If the user had code like "foo.bar" and then entered insert mode after the 'r'
in "bar", YCM would cause vim to hang.
The problem happened because a sorting task was created that would try to sort
on the latest clang result but none would be created because a clang task was
not created in this occasion. clang_data_ready_ would remain false and would
never be set to true, thus causing an infinite loop in SortingThreadMain since
the thread would forever wait on the mutex.
This was rectified with better handling of the clang results cache. Now the
cache is a full class and it also stores the line & column number of the
location for which the results were computed. Better logic is in place for the
cache invalidation.
The problem was caused by a race condition of all things. ClangCompleter would
set possibly_completions_ready when starting the first parse pass for the file
and then would try to extract diagnostics for the file before the diagnostics
were done. Technically this was not a problem because only an empty diagnostics
vector would be returned, but this triggered Syntastic because hey, we have some
diagnostics to show (even though we don't).
And then Syntastic would try to close the location list window during startup
when this operation is not available. Technically it's Syntastic's fault, but a
more principled way to check for done diagnostics is to return and use a future
for file parsing operations and this solution also works around the Syntastic
issue.
This change should fix the random hangs and segfaults when using the clang
completer. Also, assertion errors printed to the console on vim exit should go
away too, same thing with segfaults on vim exit. These "on exit" errors were
caused by not cleanly shutting down the background threads; both the identifier
completer and the clang one now join the threads on destruction. This results in
a clean shutdown.
The new clang completer architecture now uses only one clang thread (again)
instead of a completion and parsing thread. Since the parsing task needs to wait
on the completion task if it was started first (and vice-versa) there's no point
to using two threads. The desired "simplicity" of using two threads for these
two tasks actually created needless complexity (and bugs). Sigh. Such is life.
A TranslationUnit abstraction was also created and this in turn also reduces the
complexity of the clang completer.
The clang completer now also has some (very) basic tests.
The completion text in the menu is different. We used to just show the func name
in the "main" part of the completion menu, now we show the full signature
without the return type (which is shown on the right)
This should help catch cases where the user jumps to an identifier and then
edits it in place; we want to add that new ident to the db ASAP because the user
may want to have it completed soon.
Still, we're not perfect. If the user just deletes chars with 'x' or 'd' in Vim
and therefore never even enters insert mode we are obviously not going to pick
up that identifier until the next full file sweep.
Clang searches for these files and if it doesn't find them, completion is twice
as slow (or slower) than otherwise.
See this issue report for more details:

We limit the number of candidates returned to Vim to 20 and also make sure that
we are not returning any duplicate candidates. This provides a noticeable
improvement in latency.
This makes the whole plugin much faster since we now don't need to serialize and
deserialize the return values from python funcs before we can use them in Vim.
Oh God I've been waiting for something like this for so long... using this also
forces us to demand vim 7.3.584 or higher.
First off, we don't block the GUI thread anymore for ClangCompleter (that was
always temporary). Secondly, now ClangCompleter will cache the data coming from
clang so that query-based filtering of members is fast.
This change was also the root cause of the crash bug I spent two days tracking
down. The problem was that the new bool member was not added to the custom copy
ctor... since we don't really need a custom copy ctor for Result, we're going
with the compiler-provided one.
This removes the need for a special overload for AddCandidatesToDatabase. Also,
the GetFuture function now provides a more sensible API with the list being
returned instead of accepted as an out parameter.
