""""""""""""" 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 macro use '^$': this is so
" that searches over '#include " 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.
"

nmap s :cs find s =expand("")
nmap g :cs find g =expand("")

nmap t :cs find t =expand("")
nmap e :cs find e =expand("")
nmap f :cs find f =expand("")
nmap i :cs find i ^=expand("")$
nmap d :cs find d =expand("")


" Using 'CTRL-spacebar' (intepreted as CTRL-@ by vim) then a search type
" makes the vim window split horizontally, with search result displayed in
" the new window.
"
" (Note: earlier versions of vim may not have the :scs command, but it
" can be simulated roughly via:
" nmap s :cs find s =expand("")

nmap s :scs find s =expand("")

nmap t :scs find t =expand("")
nmap e :scs find e =expand("")
nmap f :scs find f =expand("")
nmap i :scs find i ^=expand("")$
nmap d :scs find d =expand("")


" Hitting CTRL-space *twice* before the search type does a vertical
" split instead of a horizontal one (vim 6 and up only)
"
" (Note: you may wish to put a 'set splitright' in your .vimrc
" if you prefer the new window on the right instead of the left

nmap s :vert scs find s =expand("")
nmap g :vert scs find g =expand("")

""""""""""""" 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
"
" Or, you can keep timeouts, by uncommenting the timeoutlen line below,
" with your own personal favorite value (in milliseconds):
"
"set timeoutlen=4000
"
" Either way, since mapping timeout settings by default also set the
" timeouts for multicharacter 'keys codes' (like ), 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 ).
"
"set ttimeout
"
" personally, I find a tenth of a second to work well for key code
" timeouts. If you experience problems and have a slow terminal or network
" connection, set it higher. If you don't set ttimeoutlen, the value for
" timeoutlent (default: 1000 = 1 second, which is sluggish) is used.
"
"set ttimeoutlen=100
