Annoying error message: ValueError: File is less than 5 lines long; not compiling.

Annoying error message: ValueError: File is less than 5 lines long; not compiling.
In YouCompleteMe\third_party\ycmd\ycmd\completers\cpp\clang_completer.py
I found: MIN_LINES_IN_FILE_TO_PARSE = 5
Why not change it to zero?

[vheon]

Can you find a C/C++ source code with less than 5 lines worth compiling for completion? Plus ss much as it could be annoying you get that only on new files and not for that long since I presume you're going to write something in that file.

Why not change it to zero?

Why take an empty file, and ask the compiler: "Can you compile this file and give me the available completion at row 0, col 0?"

[Valloric]

@strrchr The reason for the restriction is that there were problems with libclang and compiling files with no lines of code in it. This error prevents more confusing errors coming from the compiler.

The raised ValueError interrupts me when I switch buffers.
I just want YouCompleteMe keep silent when I switch buffers.
How to make it silent?

I think you can try to change line 259 of clang_completer.py
from raise ValueError( FILE_TOO_SHORT_MESSAGE ) to return
as a workaround solution

I think at least it shoud be a warning instead of error.
it is OK that YCM won't compile files less than five lines,
but it is not necessary to let users know that.

+1

The part I dislike about this is when creating an empty file with :e foo.cpp for example. This message adds one or two clicks for one to be able to start editing the new file.

We used to not inform the users that completion doesn't work when fewer than 5 lines are in the file, and then we had a HUGE number of users complaining that YCM doesn't work for them because they'd install it and try it out on a file with fewer than 5 lines in it.

It seems a pattern that such messages can mostly increase over time. Hence it's worth analyzing to put such pattern behind a gate, an option for the ones already experienced with the plugin. This is the most fair behavior I think.

The message is quite annoying, so +1 for option for disabling this behaviour

[Eddy0402]

I think you can provide a option to disable this warning, and prompt how to use the option in the warning message.
