5 " This file contains some boilerplate settings for vim's cscope interface,
6 " plus some keyboard mappings that I've found useful.

14 " your ~/.vimrc file (or cut and paste it into your .vimrc).
17 " These key maps use multiple keystrokes (2 or 3 keys). If you find that vim
18 " keeps timing you out before you can complete them, try changing your timeout
19 " settings, as explained below.

27 " This tests to see if vim was configured with the '--enable-cscope' option
28 " when it was compiled. If it wasn't, time to recompile vim...
31 """"""""""""" Standard cscope/vim boilerplate
33 " use both cscope and ctag for 'ctrl-]', ':ta', and 'vim -t'
36 " check cscope for definition of a symbol before checking ctags: set to 1
37 " if you want the reverse search order.
40 " add any cscope database in current directory

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

135 """"""""""""" key map timeouts
137 " By default Vim will only wait 1 second for each keystroke in a mapping.
138 " You may find that too short with the above typemaps. If so, you should
139 " either turn off mapping timeouts via 'notimeout'.
143 " Or, you can keep timeouts, by uncommenting the timeoutlen line below,
144 " with your own personal favorite value (in milliseconds):
148 " Either way, since mapping timeout settings by default also set the
149 " timeouts for multicharacter 'keys codes' (like <F1>), you should also
150 " set ttimeout and ttimeoutlen: otherwise, you will experience strange
151 " delays as vim waits for a keystroke after you hit ESC (it will be
152 " waiting to see if the ESC is actually part of a key code like <F1>).
156 " personally, I find a tenth of a second to work well for key code
157 " timeouts. If you experience problems and have a slow terminal or network
158 " connection, set it higher. If you don't set ttimeoutlen, the value for
159 " timeoutlent (default: 1000 = 1 second, which is sluggish) is used.
