I created systags per ':help ft-c-omni' suggestion: ctags -R -f ~/.vim/systags /usr/include /usr/local/include and added systags to &tags (set tags+=~/.vim/systags).Now I find that system() does not appear in ~/.vim/systags generated as above. This is Linux, and prototype for system() appears in /usr/include/stdlib.h I realize this is ctags issue not vim issue, but maybe someone knows what's the deal ? This is Linux
I notice the same thing. After reading your mail, I was thinking about how the popup menu can be made to show more information about the item currently being completed. I was also thinking about standard functions that exist in different programming languages (e.g., system() in the case of C). Combining the two, it's about time someone cataloged the standard functions with concise descriptions that will be displayed when the omnicompletion popup menu is employed. For functions, the prototype can be displayed to show what type of parameters the functions will accept, and also the type of their return values. This is not only limited to functions. It can be extended to standard constants and typedefs, with brief descriptions of each shown in the popup. I went ahead and constructed what I call an "omnitags" file of the standard C library, based on the ctags format at http://ctags.sourceforge.net/FORMAT with reference to both these websites: http://www.utas.edu.au/infosys/info/documentation/C/CStdLib.html http://www.phim.unibe.ch/comp_doc/c_manual/C/FUNCTIONS/funcref.htm and the GNU C library header files themselves. So far, most of the functions have been included, among a few constants, from these files: assert.h ctype.h math.h stdio.h stdlib.h string.h time.h I try to stay faithful to a particular description format that's very much like the library source code itself. At the moment, I haven't written down the rules I followed, but I feel it's quite self explanatory upon inspection. The file "c_std_omnitags", included in the attachment, can be activated by something like :set tags+=~/.vim/c_std_omnitags :setf c (then use Ctrl-x + Ctrl-o) A FileType event can be made to add the omnitags file. The file "c_std_omnitags_src" is essentially the same file, except that the tags are sorted according to header files. Work is done on the src file. All tags in the src need to be sorted in alphabetical order before being applied to the 'tags' option. I don't have much experience with omnicompletion and the intricacies of C, so I'd like to ask everyone about this omnitags idea. Would this be useful? Has this sort of thing been implemented before for Vim? If this is useful, perhaps we could form a support group to maintain omnitags files from different languages, and also different variants of the same language. The popup menu could be made to include a (cascaded) description popup to allow for a multiple-line desciptions instead of the current single-line descriptions. Feedbacks appreciated :) -- Gerald
