Do not insert parentheses when completing function #412
Description
Observed behavior
I'm using ccls+LanguageClient as a source for completion items for deoplete for C files in Neovim. Say that we have this C file:
If I start typing foo, the completion menu presents me with the options foo_noarg, which is a function that takes no arguments, and foo_witharg, a function that takes one argument.
The "newText" completion string of foo_noarg is "foo_noarg()", with both parentheses inserted
The "newText" completion string of foo_witharg is "foo_witharg(", with only the left parenthesis inserted
Preferred behavior
Though I understand the rationale for this design choice, I would like to be given the option of not automatically inserting parentheses.
The first reason is that parentheses are not needed when assigning to a function pointer, e.g.:
typedef void (* fp)();
fp foo = foo_noarg;The second reason is that I use a Vim plugin that, when pressing ), brings the cursor to the next closing parenthesis in the buffer, rather than inserting a parenthesis. This requires that all opening parentheses have a matching closing parenthesis, which, in the case of foo_witharg(, is not true.
The first reason is more generic, the second more personal, but I think it would be great to at least give the user the option to choose whether to auto-insert parentheses or not.
