Subject: Re: Bug: cscope interface should use absolute paths
To: A. S. Budden
Al -
When using cscope, the path as provided to the "cs add" command is
used. If the working directory changes, this is potentially no longer
valid. This causes me a problem as I have a plugin that tries to
pause cscope and restart it (so it can regenerate cscope.out without
access conflicts). It does this by parsing "cs show" to get the file
name(s) and then doing "cs kill" to pause and "cs add" to restart. If
the working directory has changed, "cs add" fails.
IIUC, the solution to this is to provide as an optional argument to the
":cs add" command the path from which cscope.out was generated, e.g. as
follows:
" remember where I keep my sources:
" this means the parent of src/ runtime/ etc.
if 1
let $VIMSRC = '/root/.build/vim/vim-hg/vim'
endif
if has('cscope')
set cst
if has('quickfix')
set csqf=s-,c-,d-,i-,t-,e-
endif
if version < 700
cnoreabbrev csa cs add
cnoreabbrev csf cs find
cnoreabbrev csk cs kill
cnoreabbrev css cs show
cnoreabbrev csh cs help
else
cnoreabbrev <expr> csa ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
add' : 'csa')
cnoreabbrev <expr> csf ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
find' : 'csf')
cnoreabbrev <expr> csk ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
kill' : 'csk')
cnoreabbrev <expr> css ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
show' : 'css')
cnoreabbrev <expr> csh ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
help' : 'csh')
endif
command -bar Cscope cs add $VIMSRC/src/cscope.out $VIMSRC/src
set csverb
endif
The ":if 1" is to avoid an error in a minimal-features Vim compiled with
no expression evaluation.
Best regards,

THEOREM: VI is perfect.
PROOF: VI in roman numerals is 6. The natural numbers < 6 which divide
6 are
1, 2, and 3. 1+2+3 = 6. So 6 is a perfect number. Therefore, VI is
perfect.
