|

" -- vim 5: Stick this file somewhere and 'source cscope.vim' it from
|
|
" your ~/.vimrc file (or cut and paste it into your .vimrc).
|
|
"
|
|
" NOTE:
|
|
" These key maps use multiple keystrokes (2 or 3 keys). If you find that vim

""""""""""""" My cscope/vim key mappings
|
|
"
|
|
" The following maps all invoke one of the following cscope search types:
|
|
"
|
|
" 's' symbol: find all references to the token under cursor
|
|
" 'g' global: find global definition(s) of the token under cursor
|
|
" 'c' calls: find all calls to the function name under cursor
|
|
" 't' text: find all instances of the text under cursor
|
|
" 'e' egrep: egrep search for the word under cursor
|
|
" 'f' file: open the filename under cursor
|
|
" 'i' includes: find files that include the filename under cursor
|
|
" 'd' called: find functions that function under cursor calls
|
|
"
|
|
" Below are three sets of the maps: one set that just jumps to your
|
|
" search result, one that splits the existing vim window horizontally and
|
|
" diplays your search result in the new window, and one that does the same
|
|
" thing, but does a vertical split instead (vim 6 only).
|
|
"
|
|
" I've used CTRL-\ and CTRL-@ as the starting keys for these maps, as it's
|
|
" unlikely that you need their default mappings (CTRL-\'s default use is
|
|
" as part of CTRL-\ CTRL-N typemap, which basically just does the same
|
|
" thing as hitting 'escape': CTRL-@ doesn't seem to have any default use).
|
|
" If you don't like using 'CTRL-@' or CTRL-\, , you can change some or all
|
|
" of these maps to use other keys. One likely candidate is 'CTRL-_'
|
|
" (which also maps to CTRL-/, which is easier to type). By default it is
|
|
" used to switch between Hebrew and English keyboard mode.
|
|
"
|
|
" All of the maps involving the <cfile> macro use '^<cfile>$': this is so
|
|
" that searches over '#include <time.h>" return only references to
|
|
" 'time.h', and not 'sys/time.h', etc. (by default cscope will return all
|
|
" files that contain 'time.h' as part of their name).
|
|
|
|
|
|
" To do the first type of search, hit 'CTRL-\', followed by one of the
|
|
" cscope search types above (s,g,c,t,e,f,i,d). The result of your cscope
|
|
" search will be displayed in the current window. You can use CTRL-T to
|
|
" go back to where you were before the search.

""""""""""""" key map timeouts
|
|
"
|
|
" By default Vim will only wait 1 second for each keystroke in a mapping.
|
|
" You may find that too short with the above typemaps. If so, you should
|
|
" either turn off mapping timeouts via 'notimeout'.
|
|
"
|
|
"set notimeout

|
"

|

" Either way, since mapping timeout settings by default also set the
|
|
" timeouts for multicharacter 'keys codes' (like <F1>), you should also
|
|
" set ttimeout and ttimeoutlen: otherwise, you will experience strange
|
|
" delays as vim waits for a keystroke after you hit ESC (it will be

" waiting to see if the ESC is actually part of a key code like <F1>).

"

|
" personally, I find a tenth of a second to work well for key code

" connection, set it higher. If you don't set ttimeoutlen, the value for
